Gynecologic Oncology. doi:10.1016/j.ygyno.2022.12.017More infoThe Lifestyle Intervention for oVarian cancer Enhanced Survival (LIVES) is a national study of a combined diet and physical activity intervention for stage II-IV ovarian cancer survival, an under-represented cancer in lifestyle behavioral intervention research. Here, we present the data on recruitment, retention, and baseline demographic, clinical and lifestyle behavior characteristics of the LIVES study participants.The LIVES study (NRG Oncology/GOG 0225) is a Phase III diet plus physical activity intervention trial testing the hypothesis that ovarian cancer survivors in the lifestyle intervention will demonstrate better progression-free survival than those in the control condition. Study interventions were delivered via centralized telephone-based health coaching. Baseline descriptive statistics were computed for demographic, clinical, and lifestyle behavior characteristics.The LIVES study exceeded its recruitment goals, enrolling 1205 ovarian cancer survivors from 195 NRG/NCORP-affiliated oncology practices across 49 states from 2012 to 2018. The mean age of enrollees was 59.6 years; the majority (69.4%) with stage III disease; 89% White, 5.5% Hispanic; 64% overweight/obese. Baseline self-reported diet showed a mean daily intake of 6.6 servings of fruit and vegetables, 62.7 fat grams, and 21.7 g of fiber. Physical activity averaged 13.0 MET-hours/week of moderate to vigorous physical activity; 50.9 h/week of sedentary time. Retention rates exceeded 88%.The LIVES study demonstrates efficiency in recruiting and retaining ovarian cancer survivors in a 24-month study of diet and physical activity intervention with a primary endpoint of progression free survival that will be reported.ClinicalTrials.govNCT00719303.

Association between urinary phthalate biomarker concentrations and adiposity among postmenopausal women. Environmental research, 222, 115356.More infoObesity is a leading risk factor for chronic diseases, potentially related to excess abdominal adiposity. Phthalates are environmental chemicals that have been suggested to act as obesogens, driving obesity risk. For the associations between phthalates and adiposity, prior studies have focused primarily on body mass index. We hypothesize that more refined measures of adiposity and fat distribution may provide greater insights into these associations given the role of central adiposity in chronic disease risk.

Circulating vitamin D and breast cancer risk: an international pooling project of 17 cohorts. European journal of epidemiology, 38(1), 11-29.More infoLaboratory and animal research support a protective role for vitamin D in breast carcinogenesis, but epidemiologic studies have been inconclusive. To examine comprehensively the relationship of circulating 25-hydroxyvitamin D [25(OH)D] to subsequent breast cancer incidence, we harmonized and pooled participant-level data from 10 U.S. and 7 European prospective cohorts. Included were 10,484 invasive breast cancer cases and 12,953 matched controls. Median age (interdecile range) was 57 (42-68) years at blood collection and 63 (49-75) years at breast cancer diagnosis. Prediagnostic circulating 25(OH)D was either newly measured using a widely accepted immunoassay and laboratory or, if previously measured by the cohort, calibrated to this assay to permit using a common metric. Study-specific relative risks (RRs) for season-standardized 25(OH)D concentrations were estimated by conditional logistic regression and combined by random-effects models. Circulating 25(OH)D increased from a median of 22.6 nmol/L in consortium-wide decile 1 to 93.2 nmol/L in decile 10. Breast cancer risk in each decile was not statistically significantly different from risk in decile 5 in models adjusted for breast cancer risk factors, and no trend was apparent (P-trend = 0.64). Compared to women with sufficient 25(OH)D based on Institute of Medicine guidelines (50-

The Breast Cancer Weight Loss trial (Alliance A011401): A description and evidence for the lifestyle intervention. Obesity (Silver Spring, Md.), 30(1), 28-38.More infoThe Breast Cancer Weight Loss (BWEL) trial is a randomized controlled trial designed to determine whether weight loss after a breast cancer diagnosis can reduce the risk of cancer recurrence in women with overweight or obesity. The BWEL trial will compare the efficacy of a telephone-based weight-loss intervention plus health education materials versus health education materials alone on invasive disease-free survival in 3,181 women with stage II or III breast cancer and BMI > 27 kg/m . This report provides a detailed description of the goals and methods of the lifestyle intervention and the evidence supporting the intervention used in the BWEL trial. The intervention's primary goal for participants is to achieve and maintain a weight loss ≥ 10% of baseline weight through increased physical activity and caloric restriction. The evidence supporting the diet, physical activity, and behavioral components of this telephone-based weight-loss intervention, as well as strategies to promote participant engagement and retention, is described. The intervention is provided through 42 sessions delivered by trained health coaches over a 2-year period. If the BWEL lifestyle intervention is successful in improving cancer outcomes, then weight loss will be incorporated into the care of thousands of breast cancer patients.

Nonalcoholic Fatty Liver Disease and Associated Risk Factors in a Community-Based Sample of Mexican-Origin Adults. Hepatology communications, 6(6), 1322-1335.More infoThe incidence of nonalcoholic fatty liver disease (NAFLD) is highest among Mexican-origin (MO) adults. Few studies have estimated the prevalence of NAFLD in this subpopulation, particularly by sex and age. We assessed the prevalence of NAFLD in a community sample of MO adults residing in a border region of southern Arizona and determined risk factors associated with NAFLD. A total of 307 MO adults (n = 194 women; n = 113 men) with overweight or obesity completed an in-person study visit, including vibration-controlled transient elastography (FibroScan) for the assessment of NAFLD status. A continuous attenuation parameter score of ≥288 dB/m (≥5% hepatic steatosis) indicated NAFLD status. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for NAFLD. We identified 155 participants (50%) with NAFLD, including 52% of women and 48% of men; there were no sex differences in steatosis (men, 287.8 dB/m; women, 288.4 dB/m). Sex, age, patatin-like phospholipase domain containing 3 (PNPLA3) risk allele carrier status, comorbidities, and cultural and behavioral variables were not associated with NAFLD status. There was some evidence for effect modification of body mass index (BMI) by sex (P = 0.08). The estimated OR for an increase in BMI of 5 kg/m was 3.36 (95% CI, 1.90, 5.91) for men and 1.92 (95% CI, 1.40, 2.64) for women. In post hoc analyses treating steatosis as a continuous variable in a linear regression, significant effect modification was found for BMI by sex (P = 0.03), age (P = 0.05), and PNPLA3 risk allele carrier status (P = 0.02). Conclusion: Lifestyle interventions to reduce body weight, with consideration of age and genetic risk status, are needed to stem the higher rates of NAFLD observed for MO populations.

(2022). Taking action to advance the study of race and ethnicity: the Women's Health Initiative (WHI). Women's midlife health, 8(1), 1.More info"Race" and "ethnicity" are socially constructed terms, not based on biology - in contrast to biologic ancestry and genetic admixture - and are flexible, contested, and unstable concepts, often driven by power. Although individuals may self-identify with a given race and ethnic group, as multidimensional beings exposed to differential life influencing factors that contribute to disease risk, additional social determinants of health (SDOH) should be explored to understand the relationship of race or ethnicity to health. Potential health effects of structural racism, defined as "the structures, policies, practices, and norms resulting in differential access to goods, services, and opportunities of society by "race," have been largely ignored in medical research. The Women's Health Initiative (WHI) was expected to enroll a racially and ethnically diverse cohort of older women at 40 U.S. clinical centers between 1993 and 1998; yet, key information on the racial and ethnic make-up of the WHI cohort of 161,808 women was limited until a 2020-2021 Task Force was charged by the WHI Steering Committee to better characterize the WHI cohort and develop recommendations for WHI investigators who want to include "race" and/or "ethnicity" in papers and presentations. As the lessons learned are of relevance to most cohorts, the essence of the WHI Race and Ethnicity Language and Data Interpretation Guide is presented in this paper. Recommendations from the WHI Race and Ethnicity Language and Data Interpretation Guide include: Studies should be designed to include all populations and researchers should actively, purposefully and with cultural-relevance, commit to recruiting a diverse sample; Researchers should collect robust data on race, ethnicity and SDOH variables that may intersect with participant identities, such as immigration status, country of origin, acculturation, current residence and neighborhood, religion; Authors should use appropriate terminology, based on a participant's self-identified "race" and "ethnicity", and provide clear rationale, including a conceptual framework, for including race and ethnicity in the analytic plan; Researchers should employ appropriate analytical methods, including mixed-methods, to study the relationship of these sociocultural variables to health; Authors should address how representative study participants are of the population to which results might apply, such as by age, race and ethnicity.

(2022). The impact of social rhythm and sleep disruptions on waist circumference after job loss: A prospective 18-month study. Obesity (Silver Spring, Md.), 30(10), 2023-2033.More infoThis study prospectively examined change in waist circumference (WC) as a function of daily social rhythms and sleep in the aftermath of involuntary job loss. It was hypothesized that disrupted social rhythms and fragmented/short sleep after job loss would independently predict gains in WC over 18 months and that resiliency to WC gain would be conferred by the converse.

Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 30(6), 4781-4788.More infoCaregivers of cancer patients find it challenging to perform their roles and to meet the demands of caregiving. Spirituality has been investigated as a potential coping strategy employed by caregivers, yet spirituality and related practices vary among cultural groups. In this study, we investigated the relationship between spirituality and health-related quality of life (HRQOL) and evaluated mediation effects of loneliness on this relationship. The sample was 234 lower socioeconomic status (SES) Hispanic caregivers of breast cancer survivors using existing data from the Support for Latinas with Breast Cancer and Their Intimate and Family Partners study, funded by the American Cancer Society (Badger, PI). A cross-sectional analysis was conducted at baseline, using self-reported spirituality, loneliness, and HRQOL data collected from 2012 to 2017. The exposures and outcomes were assessed using the Spiritual Well-Being Scale, the Social Isolation-Short Form 8a PROMIS Item Bank v2.0 scale, and the Global Health Scale PROMIS v.1.0/1.1 scale. Descriptive and mediation analyses using the Preacher and Hayes' approach were conducted to estimate the direct effect of spirituality on HRQOL and the indirect effect of spirituality through mediation of loneliness in relation to HRQOL. A positive association between spirituality and HRQOL was found, whereas loneliness was inversely associated with HRQOL (b = - .18, SE = .03, p

Inquiry : a journal of medical care organization, provision and financing, 59, 469580221093183.More infoLay health workers (LHWs) have been effective in delivering health promotion to underserved, vulnerable populations. Hair stylists are well positioned to serve as LHWs in addressing health disparities among Black women in the U.S. The purpose of this qualitative study was to explore the extent to which hair stylists influence their Black female clients and clients' preferences for their stylist's role in salon-based health promotion programming. Eight virtual platform focus groups were conducted with Black women (n = 39) who receive hair care services from a licensed hair stylist across the U.S. Most participants had a college degree (89.8%), health insurance (92.3%), a primary care provider (89.7%), and the majority had at least one chronic disease (56.4%). Participants reported higher potential for influence related to level of trust in the stylists and for stylists they find relatable and credible. Trust, relatability, and credibility were further determined by racial and gender congruence. Client interviewees felt stylists should model healthy behaviors and reported they may not be receptive to stylist-delivered health promotion out of the context of a hair-health connection. In this sample of well-educated clients, there was an expressed preference for stylists to provide referral to healthcare professionals or solicit experts for health topics out of the scope of haircare rather than guide the health promotion efforts themselves. Findings from this study can inform future development of acceptable salon-based, stylist-led health promotion programs that partner stylists with health experts to deliver health promotion.

American Cancer Society nutrition and physical activity guideline for cancer survivors. CA: a cancer journal for clinicians, 72(3), 230-262.More infoThe overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.

The interviews explored the impact of cancer on lifestyle and treatment-related symptoms, perception of lifestyle as an influence on health after cancer, and intervention content and delivery preferences. Interviews were analyzed using a deductive thematic approach grounded in the Quality of Cancer Survivorship Care Framework..Key survivor themes included perception of Mexican diet as unhealthy, need for reliable diet-related information, perceived benefits of physical activity after cancer treatment, family support for healthy lifestyles (physical and emotional), presence of cancer-related symptoms interfering with lifestyle, and financial barriers to living a healthy lifestyle. Among caregivers, key themes included effects of the cancer caregiving experience on caregivers' lifestyle and cancer-preventive behaviors and gratification in providing support to the survivors..The interviews revealed key considerations to the adaptation, development, and implementation of a theory-informed, evidence-based, culturally relevant lifestyle program to support lifestyle behavior change among Mexican-origin Hispanic survivors of cancer living in border communities. Our qualitative findings highlight specific strategies that can be implemented in health promotion programming aimed at encouraging cancer protective behaviors to reduce the burden of cancer and comorbidities in Mexican-origin survivors of cancer living in border communities.

Prostate Cancer and Prostatic Diseases, 1-7. doi:10.1038/s41391-021-00346-zMore infoBACKGROUND Androgen deprivation therapy (ADT) for prostate cancer is associated with adverse effects, such as obesity and metabolic syndrome, which increase cardiovascular risk, the most common cause of non-cancer mortality in men diagnosed with prostate cancer. The Comprehensive Lifestyle Improvement Program for Prostate Cancer (CLIPP) was created to determine the feasibility of conducing a comprehensive lifestyle modification intervention in men on ADT for prostate cancer and determine its early efficacy in reducing obesity and metabolic syndrome. METHODS A single-arm, open-label clinical trial was conducted by recruiting 31 men diagnosed with prostate cancer and exposed to ADT within the last 5 years. A multicomponent lifestyle modification program was delivered weekly for 16 weeks by a trained health coach. This was followed by 8 weeks of passive follow-up resulting in a total trial duration of 24 weeks. Feasibility was determined by calculating study recruitment, retention, and adherence rates. Weight and components of metabolic syndrome (waist circumference, triglycerides (TG), high-density lipoprotein (HDL), serum glucose, and blood pressure (BP)) were measured at baseline, 12, and 24 weeks. RESULTS Recruitment, retention, and adherence rates were 47.1%, 90.3%, and 100%, respectively. Statistically significant improvements were noted between baseline and end of study measurements for weight (206.3 vs. 191.3 lbs, p < 0.001), waist (41.3 vs. 38.8 inches, p < 0.001), systolic BP (144.1 vs. 133.4 mm of Hg, p = 0.014), diastolic BP (83.3 vs. 76.2 mm of Hg, p = 0.0056), TG (146.0 vs. 113.8 mg/dl, p = 0.022), HDL (51.1 vs. 55.0 mg/dl, p = 0.012), and serum glucose (114.0 vs. 103.2 mg/dl, p = 0.013). CONCLUSION CLIPP demonstrates feasibility and early efficacy of a multicomponent lifestyle modification intervention toward addressing obesity as well as components of metabolic syndrome in men on ADT for prostate cancer. This study provides strong preliminary data to develop future clinical trials in this population.

Interventions for Loneliness Among Adult Cancer Survivors: A Systematic Review and Meta-Analysis. Journal of psychosocial oncology, 1-45.More infoLoneliness is common after cancer, contributing to poor outcomes. Interventions to modify loneliness are needed. This systematic review describes the current literature regarding loneliness interventions in cancer survivors. Databases including: Ovid/MEDLINE; The Cochrane Central Register of Controlled Trials (CENTRAL); Elsevier/Embase; Clarivate/Web of Science (Core Collection), EBSCO/PsycINFO, EBSCO/CINAHL were used to perform a systematic review of literature using PRISMA guidelines. Second, risk of bias, meta-analysis and a narrative synthesis approach was completed to synthesize findings from multiple studies. Six thousand five hundred three studies were initially evaluated; eight studies met inclusion criteria. Findings indicate a paucity of interventions, generally of lower quality. Interventions were feasible and acceptable; those interventions with cultural modifications were more likely to demonstrate effectiveness. There are limited interventions addressing loneliness in cancer survivors. Development and testing of culturally-relevant programs are warranted. Current studies suggest the psychosocial symptom of loneliness is modifiable among adult cancer survivors. Few interventions have been tested and shown to be effectiveness in cancer survivors in the U.S. and none have been tailored for older adult survivors, by patient gender/sex and few for specific race/ethnic groups. Results from this systematic review: a narrative synthesis and meta-analysis can inform future interventions targeting loneliness in this growing, yet vulnerable, adult cancer survivor population.

Assessing Interactions between and Dietary Intake on Liver Steatosis in Mexican-Origin Adults. International journal of environmental research and public health, 18(13).More infoMexican-origin (MO) adults have among the highest rates of nonalcoholic fatty liver disease (NAFLD) placing them at increased risk of liver cancer. Evidence suggests that a single nucleotide polymorphism (SNP) in the gene, rs738409, increases the risk and progression of NAFLD and may modify the relationship between certain dietary factors and liver steatosis. The purpose of this study was to identify whether interactions exist between specific dietary factors and rs738409 genotype status among MO adults in relation to levels of liver steatosis. We analyzed cross-sectional data from a sample of 288 MO adults. Participants completed at least two 24-h dietary recalls. Multiple linear regression was performed assuming an additive genetic model to test the main effects of several dietary variables on levels of hepatic steatosis, adjusting for covariates. To test for effect modification, the product of the genotype and the dietary variable was included as a covariate in the model. No significant association between dietary intake and level of hepatic steatosis was observed, nor any significant gene-diet interactions. Our findings suggest that dietary intake may have the same magnitude of protective or deleterious effect even among MO adults with high genetic risk for NAFLD and NAFLD progression.

Awareness, Knowledge, and Misperceptions Related to Nonalcoholic Fatty Liver Disease in a Community Sample of Mexican-Origin Women: A Mixed Methods Study. Frontiers in public health, 9, 626428.More infoMexican-origin women suffer disproportionate rates of nonalcoholic fatty liver disease (NAFLD) and research on how to tailor NAFLD treatment interventions for this population is lacking. The purpose of this study was to assess awareness, knowledge, perceptions, and information sources related to NAFLD in a community-based sample of Mexican-origin women. This study employed a convergent parallel mixed-methods approach and consisted of a brief questionnaire ( = 194) and interviews ( = 26) among Mexican-origin women recruited from community-based settings including health fairs, churches, and community events. Participants were eligible if they identified as Mexican-origin, had a BMI ≥ 25 kg/m, were 18-64 years of age, had the ability to speak, read, and write in English and/or Spanish, and provided informed consent. A purposeful sampling approach was used to recruit a subset of women ( = 26) with confirmed liver steatosis indicative of NAFLD (controlled attenuation parameter ≥280 dB/m) who completed the questionnaire. The twenty-six participants then completed one on one, in-depth semi-structured interviews to ascertain their knowledge and understanding of NAFLD. Qualitative findings revealed low awareness of risk factors for liver disease, NAFLD specifically. Knowledge of liver disease tended to center around cirrhosis, a condition many participants reported was prevalent in their families. Quantitative and qualitative findings both found information sources for NAFLD and liver disease to be predominantly friends, family, and media. Interviews revealed a misperception related to NAFLD risk that liver disease was only caused by high alcohol intake. Low levels of NAFLD awareness and knowledge warrant the need for greater efforts to educate the general population, perhaps by integrating NAFLD education into existing type 2 diabetes educational campaigns and prevention interventions. Additionally, further elicitation research conducted in Mexican-origin adults is needed to elucidate key factors within behavioral-theory constructs that can be targeted in future interventions tailored to this unique population.

The American journal of clinical nutrition, 113(5), 1083-1092.More infoThe dietary modification (DM) clinical trial, within the Women's Health Initiative (WHI), studied a low-fat dietary pattern intervention that included guidance to increase vegetables, fruit, and grains. This study was motivated in part from uncertainty about the reliability of observational studies examining the association between dietary fat and chronic disease risk by using self-reported dietary data. In addition to this large trial, which had breast and colorectal cancer as its primary outcomes, a substantial biomarker research effort was initiated midway in the WHI program to contribute to nutritional epidemiology research more broadly. Here we review and update findings from the DM trial and from the WHI nutritional biomarker studies and examine implications for future nutritional epidemiology research. The WHI included the randomized controlled DM trial (n = 48,835) and a prospective cohort observational (OS) study (n = 93,676), both among postmenopausal US women, aged 50-79 y when enrolled during 1993-1998. Also reviewed is a nutrition and physical activity assessment study in a subset of 450 OS participants (2007-2009) and a related controlled feeding study among 153 WHI participants (2010-2014). Long-term follow-up in the DM trial provides evidence for intervention-related reductions in breast cancer mortality, diabetes requiring insulin, and coronary artery disease in the subset of normotensive healthy women, without observed adverse effects or changes in all-cause mortality. Studies of intake biomarkers, and of biomarker-calibrated intake, suggest important associations of total energy intake and macronutrient dietary composition with the risk for major chronic diseases among postmenopausal women. Collectively these studies argue for a nutrition epidemiology research agenda that includes major efforts in nutritional biomarker development, and in the application of biomarkers combined with self-reported dietary data in disease association analyses. We expect such efforts to yield novel disease association findings and to inform disease prevention approaches for potential testing in dietary intervention trials. This trial was registered at clinicaltrials.gov as NCT00000611.

They also completed the Beck Depression Inventory II (BDI-II) and participated in standardized waist circumference measurements (cm)..A significant interaction emerged between SRM and BDI-II demonstrating that less consistent social rhythms were associated with larger waist circumference at lower levels of depressive symptoms. Additional exploratory analyses demonstrated a positive association between the number of daily activities performed alone and waist circumference when controlling for symptoms of depression..These findings are the first to demonstrate a relationship between social rhythm stability and abdominal adiposity in adults who have recently, involuntarily lost their jobs. Results highlight the moderating role of depressive symptoms on daily routine in studies of metabolic health. Future prospective analysis is necessary to examine causal pathways.

A Low-Glucose Eating Pattern Improves Biomarkers of Postmenopausal Breast Cancer Risk: An Exploratory Secondary Analysis of a Randomized Feasibility Trial. Nutrients, 13(12).More infoPostmenopausal breast cancer is the most common obesity-related cancer death among women in the U.S. Insulin resistance, which worsens in the setting of obesity, is associated with higher breast cancer incidence and mortality. Maladaptive eating patterns driving insulin resistance represent a key modifiable risk factor for breast cancer. Emerging evidence suggests that time-restricted feeding paradigms (TRF) improve cancer-related metabolic risk factors; however, more flexible approaches could be more feasible and effective. In this exploratory, secondary analysis, we identified participants following a low-glucose eating pattern (LGEP), defined as consuming energy when glucose levels are at or below average fasting levels, as an alternative to TRF. Results show that following an LGEP regimen for at least 40% of reported eating events improves insulin resistance (HOMA-IR) and other cancer-related serum biomarkers. The magnitude of serum biomarkers changes observed here has previously been shown to favorably modulate benign breast tissue in women with overweight and obesity who are at risk for postmenopausal breast cancer. By comparison, the observed effects of LGEP were similar to results from previously published TRF studies in similar populations. These preliminary findings support further testing of LGEP as an alternative to TRF and a postmenopausal breast cancer prevention strategy. However, results should be interpreted with caution, given the exploratory nature of analyses.

Cardiometabolic risk factors and survival after cancer in the Women's Health Initiative.. Cancer, 127(4), 598-608. doi:10.1002/cncr.33295More infoCardiometabolic abnormalities are a leading cause of death among women, including women with cancer..This study examined the association between prediagnosis cardiovascular health and total and cause-specific mortality among 12,076 postmenopausal women who developed local- or regional-stage invasive cancer in the Women's Health Initiative (WHI). Cardiovascular risk factors included waist circumference, hypertension, high cholesterol, and type 2 diabetes. Obesity-related cancers included breast cancer, colorectal cancer, endometrial cancer, kidney cancer, pancreatic cancer, ovarian cancer, stomach cancer, liver cancer, and non-Hodgkin lymphoma. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for important predictors of survival..After a median follow-up of 10.0 years from the date of the cancer diagnosis, there were 3607 total deaths, with 1546 (43%) due to cancer. Most participants (62.9%) had 1 or 2 cardiometabolic risk factors, and 8.1% had 3 or 4. In adjusted models, women with 3 to 4 risk factors (vs none) had a higher risk of all-cause mortality (HR, 1.99; 95% CI, 1.73-2.30), death due to cardiovascular disease (CVD) (HR, 4.01; 95% CI, 2.88-5.57), cancer-specific mortality (HR, 1.37; 95% CI, 1.1-1.72), and other-cause mortality (HR, 2.14; 95% CI, 1.70-2.69). A higher waist circumference was associated with greater all-cause mortality (HR, 1.17; 95% CI, 1.06-1.30) and cancer-specific mortality (HR, 1.22; 95% CI, 1.04-1.42)..Among postmenopausal women diagnosed with cancer in the WHI, cardiometabolic risk factors before the cancer diagnosis were associated with greater all-cause, CVD, cancer-specific, and other-cause mortality. These results raise hypotheses regarding potential clinical intervention strategies targeting cardiometabolic abnormalities that require future prospective studies for confirmation..This study uses information from the Women's Health Initiative (WHI) to find out whether cardiac risk factors are related to a greater risk of dying among older women with cancer. The WHI is the largest study of medical problems faced by older women in this country. The results show that women who have 3 or 4 risk factors are more likely to die of any cause, heart disease, or cancer in comparison with women with no risk factors. It is concluded that interventions to help to lower the burden of cardiac risk factors can have an important impact on survivorship among women with cancer.

Relationship Between Individual Health Beliefs and Fruit and Vegetable Intake and Physical Activity Among Cancer Survivors: Results from the Health Information National Trends Survey. Journal of adolescent and young adult oncology.More infoThe aim of this study was to describe diet and physical activity (PA) behaviors and health beliefs among cancer survivors and identify potential differences between adolescent and young adult (AYA) and adult/older cancer survivors. Cancer survivors ( = 1864) participating in the Health Information National Trends Survey (HINTS) provided responses regarding diet and PA and selected health beliefs related to general health and cancer (self-efficacy, attitudinal belief, normative belief, risk belief, intention, and self-regulation). Health belief associations with diet and PA were assessed using adjusted logistic regression models, and multiple linear regression was used for a computed Modified American Cancer Society Adherence score (0-10, higher score indicates higher adherence to recommendations); age at diagnosis was evaluated as a potential effect modifier. Health behaviors between AYA and adult/older were not significantly different; a greater percent of AYA met fruit and resistance PA recommendations. Higher health self-efficacy was associated with meeting aerobic PA recommendations (odds ratio [OR]: 1.71; confidence interval [95% CI]: 1.13-2.60; = 0.01). Higher intention was inversely related to meeting vegetable recommendation (OR: 0.58; 95% CI: 0.35-0.97; = 0.04). Self-regulation was associated with higher odds of meeting each recommendation.

A Telephone-Based Tobacco Cessation Program in the State of Qatar: Protocol of a Feasibility Study.. International journal of environmental research and public health, 18(9). doi:10.3390/ijerph18094750More infoIn Qatar, tobacco is the leading preventable cause of death and disease. Telephone-based interventions for smoking are cost-effective and scalable interventions that are effective in promoting smoking behavior change. While many countries have implemented these services within their tobacco control programs, there is a distinct dearth of a telephone-based smoking cessation intervention that is adapted and tailored to meet the needs of people who smoke in Qatar. This study presents the protocol of a primary health care center integrated smoking quitline program in Qatar. Participants will be recruited from seven smoking clinics (recruitment sites). Trained clinic staff will provide brief advice on quitting followed by a referral to the quitline. Eligible participants (male smokers over 18 years of age) will complete baseline questionnaires and receive five weekly proactive counseling calls, an end-of-treatment assessment (approx. 1 week after Session 5), and 1- and 3-month follow-up assessments. The main aim of this study is to assess the feasibility and acceptability, which include the recruitment and retention rate, compliance to pharmacotherapy, and participant satisfaction. This is the first study to integrate an evidence-based smoking cessation intervention delivered via telephone within the healthcare system in Qatar. If effective, results can inform the development of a large-scale telephone-based program that widely reaches users of tobacco in Qatar as well as in the Middle East.

Journal of Cancer Survivorship, 15(3), 461-469. doi:10.1007/s11764-020-00940-5More infoCancer survivors (CS) with ostomies may face challenges in sustaining physical activity (PA) levels and maintaining healthy diets. This analysis describes lifestyle behaviors and their relationships with health-related quality of life (HRQOL) in CS with ostomies. This is a cross-sectional, secondary analysis of a multisite randomized self-management education trial for CS with ostomies. The baseline self-reported measures were queried on aerobic PA and diet using the City of Hope Quality of Life Ostomy measure, and the Self-Efficacy to Perform Self-Management Behaviors questionnaire (SE). PA was compared against the American Cancer Society PA guidelines for CS. Relationships between PA and HRQOL were evaluated using multiple linear regression, stratified by BMI. Among 200 responders, fewer than 20% met or exceeded the PA guideline for cancer survivors; overall, confidence in the ability to perform gentle or aerobic PA was moderate (6/10 on the SE). Overall HRQOL (p = 0.038), psychological well-being (p = 0.017), and physical strength (p = 0.025) were associated with increased PA. Almost half (48.7%) of CS reported a special diet. CS with urostomies were less likely to report diet adjustments after their ostomy surgeries (OR: 0.16, 95% CI [0.08–0.38]) than CS with fecal ostomies. Better HRQOL is associated with PA guideline achievement among CS with ostomies. Additionally, diet adjustments were reported more frequently in CS with fecal ostomies. Our findings bear clinical relevance for designing ostomy self-management and lifestyle recommendations for CS with ostomies. The evaluation of lifestyle behaviors may be an especially important focus for CS with ostomies.

Sleep, 43(Supplement_1), A398-A399. doi:10.1093/sleep/zsaa056.1045More infoAbstract Introduction Obesity is a major public health concern disproportionately affecting people of lower socioeconomic status. Involuntary job loss is a predictor of economic hardship and unemployment has been associated with poor sleep quality. Little is known about daily sleep and energy intake in this high-risk population. We hypothesized that disrupted, short sleep would be associated with increased energy intake among individuals who experienced involuntary job loss within the last 90 days. Methods Complete baseline data were analyzed from the ongoing Assessing Daily Activity Patterns through occupational Transitions (ADAPT) study. Over the same two-week period, participants (n = 191; 117 female; 63 Hispanic) were instructed to complete 14 days of daily sleep diaries and up to three 24-hour dietary recalls, conducted by trained interviewers using the Nutrition Data System for Research. The primary sleep variable was a composite score summarizing standardized number of awakenings and reversed-scored total sleep time; higher scores represented worse sleep. Energy intake was estimated as average 24 hour reported kcals/day. Linear regression was employed with age, gender, and body mass index as covariates. Results Higher sleep composite scores were associated with higher self-reported intake in kilocalories (kcal), B = 84.83, SE = 38.01, t = 2.23, p < .05. Wake time after sleep onset, sleep onset latency, and sleep efficiency were not associated with energy intake. Interestingly, higher subjective sleep quality was associated with consumption of more average daily kcals. Conclusion In a sample population of adults experiencing stress and economic hardship related to job loss, sleep continuity and quantity were associated with higher energy intake. With further prospective support, these findings suggest that public health interventions for obesity may benefit from behavioral sleep intervention components targeting both sleep fragmentation and sleep restriction.

Sleep, 43(Supplement_1), A397-A398. doi:10.1093/sleep/zsaa056.1043More infoAbstract Introduction Involuntary job loss is an acute stressor that disrupts daily time structure and activity and exacerbates economic hardship and psychological distress. Studies show that unemployment is associated with negative obesity-related health outcomes, such as metabolic syndrome. However, very little is known about daily routine, depression, and obesity in individuals who have recently experienced involuntary job loss. We hypothesized that individuals with less consistent daily routines, or unstable social rhythms, after job-loss would have more abdominal adiposity than individuals with more consistent social rhythms. We also hypothesized that this relationship would vary as a function of depressive symptoms. Methods Cross-sectional baseline data (n = 186) from the ongoing ADAPT study (Assessing Daily Activity Patterns through occupational Transitions) were analyzed using linear regression techniques. Participants were predominantly female (62%) with a mean age of 41.12 years (SD = 10.16 years); 31% were Hispanic or Latino. Over two weeks, participants completed the daily Social Rhythm Metric-17 (SRM), Beck Depression Inventory II (BDI), and waist circumference (adiposity) measurements (cm). Results A significant BDI x SRM interaction was detected in the prediction of waist circumference, B = .36, SE = .18, p < .05, 95% CI [.002, .709], R2 = .07). The SRM was inversely associated with waist circumference, B = -5.57, SE = 2.25, p < .05, 95% CI [-9.98, -1.13], only at lower levels of BDI (-1 SD below the mean). Results from the Johnson-Neyman technique identified that the conditional effect of SRM on waist circumference was statistically significant at a BDI raw score of 8.33 (0-13 points is minimal depression) with ~45% of cases within this region. Conclusion A less consistent daily routine was associated with a larger waist circumference among individuals with minimal depressive symptoms. These findings are the first to demonstrate a relationship between social rhythm stability and abdominal adiposity in adults at high risk for central obesity. Results highlight the moderating role of depression in obesity prevention. Future prospective analysis is necessary to examine causal pathways. Support #1R01HL117995-01A1

Nutrition reviews.More infoDairy products have been a key component of dietary guidance in the United States for more than 100 years. In light of major advances in the understanding of dietary intake and metabolism, the aim of this review was to examine whether dairy should remain a single commodity in federal guidance. Considerations include recognizing that a substantial proportion of the world's adult population (65%-70%) exhibits lactase nonpersistence, a reduced ability to metabolize lactose to glucose and galactose. Shifts in the US population, including a greater proportion of African Americans and Asians, are of key importance because several studies have shown a markedly higher prevalence of lactase nonpersistence and, consequently, a lower dairy intake among these groups. While cow's milk alternatives are available, families who use them will pay up to an additional $1400 per year compared with those who are able to consume dairy products. Dietary guidance also contains downstream effects for government assistance, such as the US Department of Agriculture's National School Lunch Program and School Breakfast Program. For reasons like these, Canada has recently removed dairy as a separate food group in national dietary guidance. The results of the present review suggest that consideration of this modification when developing population-level guidelines in the United States is warranted.

Interventions to increase uptake of Human Papillomavirus (HPV) vaccination in minority populations: A systematic review. Preventive medicine reports, 19, 101163.More infoMinority youth represent a unique population for public health interventions given the social, economic, and cultural barriers they often face in accessing health services. Interventions to increase uptake of Human Papillomavirus (HPV) vaccination in minority youth have the potential to reduce disparities in HPV infection and HPV-related cancers. This systematic review assesses the effectiveness of interventions to increase HPV vaccine uptake, measured as vaccine series initiation and series completion, among adolescents and young adults, aged 9-26 years old, identifying as a racial and ethnic minority or sexual and gender minority (SGM) group in high-income countries. Of the 3013 citations produced by a systematic search of three electronic databases (PubMed, Embase, and Web of Science) in November 2018, nine studies involving 9749 participants were selected for inclusion. All studies were conducted in the United States and were published from 2015 to 2018. Interventions utilized education, vaccine appointment reminders, and negotiated interviewing to increase vaccination. Participants were Black or African American (44.4%), Asian (33.3%), Hispanic or Latinx (22.2%), American Indian or Alaska Native (11.1%), and SGM (22.2%). Studies enrolled parent-child dyads (33.3%), parents alone (11.1%), and youth alone (55.6%). Vaccine series initiation ranged from 11.1% to 84% and series completion ranged from 5.6% to 74.2% post-intervention. Educational and appointment reminder interventions may improve HPV vaccine series initiation and completion in minority youth in the U.S. Given the lack of high quality, adequately powered studies, further research is warranted to identify effective strategies for improving HPV vaccine uptake for minority populations.

The Lifestyle Intervention for oVarian cancer Enhanced Survival study is testing whether 1205 women randomized to a diet and physical activity intervention for 24-months will have longer progression-free survival versus attention control. Here we determine the frequency and predictors of late versus early and mid chronotypes in disease-free ovarian cancer survivors. Methods 894 ovarian cancer survivors with baseline measures were included in analyses. Chronotypes were determined using self-reported time to bed (early- < 9 pm; mid- ≥ 9 pm - ≤12 am; late- >12 am) captured through the Pittsburgh Sleep Quality Index. Demographic, diet and physical activity data were captured with validated questionnaires and BMI measured in clinic. Descriptive statistics and logistic regression, adjusted for smoking status and race, were performed. Results 12.4% of women were late chronotype with significant differences between chronotypes observed for race, smoking history, sleep duration, and physical activity (p < 0.05). Late chronotype reported fewer hours of sleep per night (6.54 ± 1.51hrs) compared to mid (7.10± 1.31hrs) and early (7.74 ± 1.30hrs) chronotype. Blacks had higher odds of being late chronotype, OR 4.28 (95% CI 2.16-8.46). Late chronotype were more likely to report a history of smoking and lower recreational activity and had a higher mean BMI of 29.1± 6.0 kg/m2 compared to mid and early chronotype 27.8± 6.2 kg/m2 and 27.4± 5.4kg/m2, respectively. No significant differences were observed for sleep or diet quality, age, education or employment status. Conclusion Results of this analysis are consistent with other community-based population studies with regard to chronotype and race. Ovarian cancer is aggressive and late chronotype are more likely to have other risk factors that elevate risk of recurrence (obesity, tobacco use and inactivity. Six-month data are being analyzed by treatment arm and will provide important insights as to the role of sleep phase and lifestyle behaviors in this vulnerable population.

American Cancer Society guideline for diet and physical activity for cancer prevention. CA: a cancer journal for clinicians, 70(4), 245-271.More infoThe American Cancer Society (ACS) publishes the Diet and Physical Activity Guideline to serve as a foundation for its communication, policy, and community strategies and, ultimately, to affect dietary and physical activity patterns among Americans. This guideline is developed by a national panel of experts in cancer research, prevention, epidemiology, public health, and policy, and reflects the most current scientific evidence related to dietary and activity patterns and cancer risk. The ACS guideline focuses on recommendations for individual choices regarding diet and physical activity patterns, but those choices occur within a community context that either facilitates or creates barriers to healthy behaviors. Therefore, this committee presents recommendations for community action to accompany the 4 recommendations for individual choices to reduce cancer risk. These recommendations for community action recognize that a supportive social and physical environment is indispensable if individuals at all levels of society are to have genuine opportunities to choose healthy behaviors. This 2020 ACS guideline is consistent with guidelines from the American Heart Association and the American Diabetes Association for the prevention of coronary heart disease and diabetes as well as for general health promotion, as defined by the 2015 to 2020 Dietary Guidelines for Americans and the 2018 Physical Activity Guidelines for Americans.

Dietary Interventions for Adult Survivors of Adolescent and Young Adult Cancers: A Systematic Review and Narrative Synthesis. Journal of adolescent and young adult oncology.More infoAdolescent and young adult (AYA) cancer survivors, here defined as individuals diagnosed with cancer between 15 and 39 years of age, are at high risk for adverse late-term metabolic effects of treatment through adulthood. Diet is a modifiable lifestyle behavior that may improve metabolic health outcomes in AYA cancer survivors. However, the details of dietary interventions for this unique population remain largely undescribed. In this systematic review, we aim to synthesize the results of dietary interventions for adult AYA cancer survivors. Seven databases and clinical trial registries were searched in March 2019 for interventions targeting dietary behaviors in AYA cancer survivors (PROPSERO systematic review number: CRD42019126376). Descriptive statistics and a narrative synthesis were completed to detail intervention participants and components. After full text review of 233 studies, four studies met all inclusion criteria. All studies were heterogeneous for participant age, cancer type, and duration, and were designed for feasibility and preliminary efficacy. Included studies followed different dietary guidance; however, each resulted in a significant change on a primary outcome of either dietary quality or body composition. Three of the four studies included a theoretical framework, where self-efficacy was a central construct. Counseling, in person, telephone, or electronic, provided behavioral support. Results of this systematic review suggest high potential to change dietary behaviors in AYA, but interventions remain limited. AYA cancer survivors demonstrate unique physiological and psychosocial needs, and future interventions designed to address this care gap should be targeted for this population with consideration of social support, delivery mode, and individual tailoring.

Journal of the National Cancer Institute, 112(9), 929-937. doi:10.1093/jnci/djz226More infoExcess body weight is an established cause of postmenopausal breast cancer, but it is unknown if weight loss reduces risk..Associations between weight change and risk of breast cancer were examined among women aged 50 years and older in the Pooling Project of Prospective Studies of Diet and Cancer. In 10 cohorts, weight assessed on three surveys was used to examine weight change patterns over approximately 10 years (interval 1 median = 5.2 years; interval 2 median = 4.0 years). Sustained weight loss was defined as no less than 2 kg lost in interval 1 that was not regained in interval 2. Among 180 885 women, 6930 invasive breast cancers were identified during follow-up..Compared with women with stable weight (±2 kg), women with sustained weight loss had a lower risk of breast cancer. This risk reduction was linear and specific to women not using postmenopausal hormones (>2-4.5 kg lost: hazard ratio [HR] = 0.82, 95% confidence interval [CI] = 0.70 to 0.96; >4.5-

International journal of cancer, 146(9), 2394-2405. doi:10.1002/ijc.32555More infoCell-mediated immune suppression may play an important role in lung carcinogenesis. We investigated the associations for circulating levels of tryptophan, kynurenine, kynurenine:tryptophan ratio (KTR), quinolinic acid (QA) and neopterin as markers of immune regulation and inflammation with lung cancer risk in 5,364 smoking-matched case-control pairs from 20 prospective cohorts included in the international Lung Cancer Cohort Consortium. All biomarkers were quantified by mass spectrometry-based methods in serum/plasma samples collected on average 6 years before lung cancer diagnosis. Odds ratios (ORs) and 95% confidence intervals (CIs) for lung cancer associated with individual biomarkers were calculated using conditional logistic regression with adjustment for circulating cotinine. Compared to the lowest quintile, the highest quintiles of kynurenine, KTR, QA and neopterin were associated with a 20-30% higher risk, and tryptophan with a 15% lower risk of lung cancer (all ptrend < 0.05). The strongest associations were seen for current smokers, where the adjusted ORs (95% CIs) of lung cancer for the highest quintile of KTR, QA and neopterin were 1.42 (1.15-1.75), 1.42 (1.14-1.76) and 1.45 (1.13-1.86), respectively. A stronger association was also seen for KTR and QA with risk of lung squamous cell carcinoma followed by adenocarcinoma, and for lung cancer diagnosed within the first 2 years after blood draw. This study demonstrated that components of the tryptophan-kynurenine pathway with immunomodulatory effects are associated with risk of lung cancer overall, especially for current smokers. Further research is needed to evaluate the role of these biomarkers in lung carcinogenesis and progression.

Comprehensive Lifestyle Improvement Program for Prostate Cancer (CLIPP): Protocol for a Feasibility and Exploratory Efficacy Study in Men on Androgen Deprivation Therapy. JMIR research protocols, 8(2), e12579.More infoAndrogen deprivation therapy (ADT) for prostate cancer is associated with adverse cardiometabolic effects such as reduced libido, hot flashes, metabolic syndrome, diabetes, myocardial infarction, and stroke. This reduces quality of life and potentially increases mortality. Several large clinical trials have demonstrated improvements in cardiometabolic risk with comprehensive multimodality lifestyle modification. However, there is a lack of data for such interventions in men on ADT for prostate cancer, and existing studies have used non-standardized interventions or lacked data on metabolic risk factors.

Does Season of Reported Dietary Intake Influence Diet Quality? Analysis From the Women's Health Initiative. American journal of epidemiology, 188(7), 1304-1310.More infoWe evaluated the role of seasonality in self-reported diet quality among postmenopausal women participating in the Women's Health Initiative (WHI). A total of 156,911 women completed a food frequency questionnaire (FFQ) at enrollment (1993-1998). FFQ responses reflected intake over the prior 3-month period, and seasons were defined as spring (March-May), summer (June-August), fall (September-November), and winter (December-February). FFQ data were used to calculate the Alternate Healthy Eating Index (AHEI), a measure of diet quality that has a score range of 2.5-87.5, with higher scores representing better diet quality. In multivariable linear regression models using winter as the reference season, AHEI scores were higher in spring, summer, and fall (all P values < 0.05); although significant, the variance was minimal (mean AHEI score: winter, 41.7 (standard deviation, 11.3); summer, 42.2 (standard deviation, 11.3)). Applying these findings to hypothesis-driven association analysis of diet quality and its relationship with chronic disease risk (cardiovascular disease) showed that controlling for season had no effect on the estimated hazard ratios. Although significant differences in diet quality across seasons can be detected in this population of US postmenopausal women, these differences are not substantial enough to warrant consideration in association studies of diet quality.

On average, women under-reported their weight by about 2 lb (0·91 kg). The discrepancies varied by age, race/ethnicity, education and BMI. Compared with normal-weight women, underweight women over-reported their weight by 3·86 lb (1·75 kg) and obese women under-reported their weight by 4·18 lb (1·90 kg) on average. The higher the degree of excess weight, the greater the under-reporting of weight. Adjusting self-reported weight for an individual's age, race/ethnicity and education yielded an identical average weight to that measured..Correlations between self-reported and measured weights in the WHI are high. Discrepancies varied by different sociodemographic characteristics, especially an individual's BMI. Correction of self-reported weight for individual characteristics could improve the accuracy of assessment of obesity status in postmenopausal women.

Ninety-three percent of participants completed the intervention, and 71% participated in active follow-up through 30 September 2015 (median 17.3 years). We measured time to development of treated diabetes and progression from oral antihyperglycemic agents to insulin. Serum glucose and insulin were measured in a subsample of women (N = 2,324) at baseline and years 1, 3, and 6..During the trial, intervention group women had lower rates of initiation of insulin therapy (hazard ratio [HR] 0.74 [95% CI 0.59, 0.94]; P = 0.01). Moreover, women with baseline waist circumference ≥88 cm (P interaction = 0.01) and worse metabolic syndrome scores (P interaction = 0.02) had the greatest reduction in risk of initiating insulin therapy. The decreased risk from the intervention was present during the cumulative follow-up (HR 0.88 [95% CI 0.78, 0.99]; P = 0.04).

Associations between ACE-Inhibitors, Angiotensin Receptor Blockers, and Lean Body Mass in Community Dwelling Older Women. Journal of aging research, 2018, 8491092.More infoStudies suggest that ACE-inhibitors (ACE-I) and angiotensin receptor blockers (ARBs) may preserve skeletal muscle with aging. We evaluated longitudinal differences in lean body mass (LBM) among women diagnosed with hypertension and classified as ACE-I/ARB users and nonusers among Women's Health Initiative participants that received dual energy X-ray absorptiometry scans to estimate body composition (=10,635) at baseline and at years 3 and 6 of follow-up. Of those, 2642 were treated for hypertension at baseline. Multivariate linear regression models, adjusted for relevant demographics, behaviors, and medications, assessed ACE-I/ARB use/nonuse and LBM associations at baseline, as well as change in LBM over 3 and 6 years. Although BMI did not differ by ACE-I/ARB use, LBM (%) was significantly higher in ACE-I/ARB users versus nonusers at baseline (52.2% versus 51.3%, resp., =0.001). There was no association between ACE-I/ARB usage and change in LBM over time. Reasons for higher LBM with ACE-I/ARB use cross sectionally, but not longitundinally, are unclear and may reflect a threshold effect of these medications on LBM that is attenuated over time. Nevertheless, ACE-I/ARB use does not appear to negatively impact LBM in the long term.

Weight management and physical activity throughout the cancer care continuum. CA: a cancer journal for clinicians, 68(1), 64-89.More infoMounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, "Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum." Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight-management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.

Lifestyle Modifications and Policy Implications for Primary and Secondary Cancer Prevention: Diet, Exercise, Sun Safety, and Alcohol Reduction. American Society of Clinical Oncology educational book. American Society of Clinical Oncology. Annual Meeting, 88-100.More infoImproved cancer treatments and cancer detection methods are not likely to completely eradicate the burden of cancer. Primary prevention of cancer is a logical strategy to use to control cancer while also seeking novel treatments and earlier detection. Lifestyle modification strategies to improve primary prevention and risk reduction for the development of cancer include choosing a healthy diet with an emphasis on plant sources, maintaining a healthy weight throughout life, being physically active, regularly using sunscreen and wearing protective clothing, limiting sun exposure during the hours of 10 AM to 2 PM, avoiding indoor tanning, and reducing or eliminating alcohol use. In addition to continued use of ongoing education of the public, health care providers, and cancer support communities, other policy and public health efforts should be pursued as well. Examples of supported and successful policy approaches are included in this article, including efforts to limit indoor tanning and improve community-wide interventions to reduce ultraviolet radiation exposure as well as to formally support various alcohol policy strategies including increasing alcohol taxes, reducing alcohol outlet density, improving clinical screening for alcohol use disorders, and limiting youth exposure to alcohol marketing and advertising. These prevention strategies are expected to have the largest impact on the development of melanoma as well as breast, colorectal, head and neck, liver, and esophageal cancers. The impact of these strategies as secondary prevention is less well understood. Areas of additional needed research and implementation are also highlighted. Future areas of needed research are the effects of these modifications after the diagnosis of cancer (as secondary prevention).

Associations of Biomarker-Calibrated Intake of Total Sugars With the Risk of Type 2 Diabetes and Cardiovascular Disease in the Women's Health Initiative Observational Study. American journal of epidemiology, 187(10), 2126-2135.More infoThe inconsistent findings from epidemiologic studies relating total sugars (TS) consumption to cardiovascular disease (CVD) or type 2 diabetes (T2D) risk may be partly due to measurement error in self-reported intake. Using regression calibration equations developed based on the predictive biomarker for TS and recovery biomarker for energy, we examined the association of TS with T2D and CVD risk, before and after dietary calibration, in 82,254 postmenopausal women participating in the Women's Health Initiative Observational Study. After up to 16 years of follow-up (1993-2010), 6,621 T2D and 5,802 CVD incident cases were identified. The hazard ratio for T2D per 20% increase in calibrated TS was 0.94 (95% confidence interval (CI): 0.77, 1.15) in multivariable energy substitution, and 1.00 (95% CI: 0.85, 1.18) in energy partition models. Multivariable hazard ratios for total CVD were 0.97 (95% CI: 0.87, 1.09) from energy substitution, and 0.91 (95% CI: 0.80, 1.04) from energy partition models. Uncalibrated TS generated a statistically significant inverse association with T2D and total CVD risk in multivariable energy substitution and energy partition models. The lack of conclusive findings from our calibrated analyses may be due to the low explanatory power of the calibration equations for TS, which could have led to incomplete deattenuation of the risk estimates.

Body mass index-stratified models were generated to investigate body mass index as a potential modifying factor..DED was associated with higher body mass index (28.9±6.0 vs 26.3±4.9) and waist circumference (89.3±14.2 vs 82.4±12.4 cm) for DED quintiles 5 vs 1, respectively. DED was associated with a 10% increased risk of any obesity-related cancer (subhazard ratioQ5 vs Q1: 1.1, 95% CI 1.03 to 1.2; P=0.004). This increased risk appeared limited to women who were normal weight at enrollment..Higher DED may be a contributing factor for obesity-related cancers, especially among normal-weight postmenopausal women and, as such, could serve as a modifiable behavior for dietary interventions to reduce obesity-associated cancer risk.

However, it is unclear if there are differences in the association between the number of RFs for HF and the risk of development of HF and death within racial/ethnic groups..In the WHI (Women's Health Initiative; 1993-2010), African-American (n=11 996), white (n=18 479), and Hispanic (n=5096) women with 1, 2, or 3+ baseline RFs were compared with women with 0 RF within their respective racial/ethnic groups to assess risk of developing HF or all-cause mortality before and after HF, using survival analyses. After adjusting for age, socioeconomic status, and hormone therapy, the subdistribution hazard ratio (95% confidence interval) of developing HF increased as number of RFs increased (P

Excess body weight has been linked to both an increased risk of developing breast cancer and poor prognosis in women diagnosed with early stage disease. A recent meta-analysis of 82 studies demonstrated that risk of breast cancer mortality was increased by 35% in women who were obese at the time of breast cancer diagnosis compared to women who were of normal weight. The Breast cancer Weight Loss (BWEL) study will evaluate the effect of weight loss after breast cancer diagnosis on risk of cancer recurrence. Methods: BWEL is a Phase III randomized trial evaluating the impact of a telephone-based weight loss intervention vs control on invasive disease-free survival (iDFS) in 3136 overweight and obese women with Stage II-III breast cancer.

Impaired functional vitamin B6 status is associated with increased risk of lung cancer.. International journal of cancer, 142(12), 2425-2434. doi:10.1002/ijc.31215More infoCirculating vitamin B6 levels have been found to be inversely associated with lung cancer. Most studies have focused on the B6 form pyridoxal 5'-phosphate (PLP), a direct biomarker influenced by inflammation and other factors. Using a functional B6 marker allows further investigation of the potential role of vitamin B6 status in the pathogenesis of lung cancer. We prospectively evaluated the association of the functional marker of vitamin B6 status, the 3-hydroxykynurenine:xanthurenic acid (HK:XA) ratio, with risk of lung cancer in a nested case-control study consisting of 5,364 matched case-control pairs from the Lung Cancer Cohort Consortium (LC3). We used conditional logistic regression to evaluate the association between HK:XA and lung cancer, and random effect models to combine results from different cohorts and regions. High levels of HK:XA, indicating impaired functional B6 status, were associated with an increased risk of lung cancer, the odds ratio comparing the fourth and the first quartiles (OR4thvs.1st ) was 1.25 (95% confidence interval, 1.10-1.41). Stratified analyses indicated that this association was primarily driven by cases diagnosed with squamous cell carcinoma. Notably, the risk associated with HK:XA was approximately 50% higher in groups with a high relative frequency of squamous cell carcinoma, i.e., men, former and current smokers. This risk of squamous cell carcinoma was present in both men and women regardless of smoking status.

Cancer Epidemiology, Biomarkers & Prevention, 26(3), 435-435. doi:10.1158/1055-9965.epi-17-0027More infoDietary supplement use is high among breast cancer survivors. One compound natural to cruciferous vegetables, diindolylmethane (DIM), is among the supplements commonly used. This bioactive compound has significant experimental evidence for bioactivity in breast chemoprevention. Sparse evidence in the form of well-designed human clinical trials exist to test its efficacy or safety. Methods: In this double-blind placebo-controlled study women taking tamoxifen for breast cancer primary or tertiary prevention were randomly assigned to receive 150 mg DIM (BioResponse(BR)-DIM) twice daily or a placebo for a minimum period of 12 months. Primary outcome was change in urinary estrogen metabolites 2-hydroxyestrone and 16α-hydroxyestrone (baseline to 6 weeks, 6 and 12 months). Secondary endpoints included breast density by mammogram and fat:water ratio MRI (baseline to 12 months) and serum estrogens (baseline to 6, 12 months). Safety data were also evaluated, including tamoxifen metabolites. Results: Adherence to study pills was >91% by pill count and urinary DIM metabolite assessment. In participants assigned DIM there was a significant and sustained shift in urinary estrogen metabolism favoring a higher 2-OH:16α-OH ratio; sex hormone binding globulin (SHBG) was also increased. No change in breast density was demonstrated. Safety analysis showed no appreciable differences in adverse events by treatment arm; however, tamoxifen metabolism for the parent compound as well as endoxifen and 4-OH endoxifen were appreciably reduced in women assigned to the DIM arm. Conclusions In this first large study of DIM in the setting of breast cancer chemoprevention, a favorable shift in estrogen metabolism and SHBG was demonstrated. However, the reduction in tamoxifen metabolites raises concern regarding the potential interaction between DIM and tamoxifen, an area in need of continued research. Impact Given the widespread and generally unsupported use of dietary supplementation by breast cancer survivors, these data will help to inform the use of DIM as a dietary supplement for breast cancer patients receiving tamoxifen.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 35(25), 2919-2926.More infoPurpose Earlier Women's Health Initiative Dietary Modification trial findings suggested that a low-fat eating pattern may reduce breast cancers with greater mortality. Therefore, as a primary outcome-related analysis from a randomized prevention trial, we examined the long-term influence of this intervention on deaths as a result of and after breast cancer during 8.5 years (median) of dietary intervention and cumulatively for all breast cancers diagnosed during 16.1 years (median) of follow-up. Patients and Methods The trial randomly assigned 48,835 postmenopausal women with normal mammograms and without prior breast cancer from 1993 to 1998 at 40 US clinical centers to a dietary intervention with goals of a reduction of fat intake to 20% of energy and an increased intake of fruits, vegetables, and grains (40%; n = 19,541) or to a usual diet comparison (60%; n = 29,294). Results In the dietary group, fat intake and body weight decreased (all P < .001). During the 8.5-year dietary intervention, with 1,764 incident breast cancers, fewer deaths occurred as a result of breast cancer in the dietary group, which was not statistically significant (27 deaths [0.016% per year] v 61 deaths [0.024% per year]; hazard ratio [HR], 0.67; 95% CI, 0.43 to 1.06; P = .08). During the same period, deaths after breast cancer (n = 134) were significantly reduced (40 deaths [0.025% per year] v 94 deaths [0.038% per year]; HR, 0.65; 95% CI, 0.45 to 0.94; P = .02) by the dietary intervention. During the 16.1-year follow-up, with 3,030 incident breast cancers, deaths after breast cancer also were significantly reduced (234 deaths [0.085% per year] v 443 deaths [0.11% per year]; HR, 0.82; 95% CI, 0.70 to 0.96; P = .01) in the dietary group. Conclusion Compared with a usual diet comparison group, a low-fat dietary pattern led to a lower incidence of deaths after breast cancer.

Longitudinal assessment of daily activity patterns on weight change after involuntary job loss: the ADAPT study protocol. BMC public health, 17(1), 793.More infoThe World Health Organization has identified obesity as one of the most visible and neglected public health problems worldwide. Meta-analytic studies suggest that insufficient sleep increases the risk of developing obesity and related serious medical conditions. Unfortunately, the nationwide average sleep duration has steadily declined over the last two decades with 25% of U.S. adults reporting insufficient sleep. Stress is also an important indirect factor in obesity, and chronic stress and laboratory-induced stress negatively impact sleep. Despite what we know from basic sciences about (a) stress and sleep and (b) sleep and obesity, we know very little about how these factors actually manifest in a natural environment. The Assessing Daily Activity Patterns Through Occupational Transitions (ADAPT) study tests whether sleep disruption plays a key role in the development of obesity for individuals exposed to involuntary job loss, a life event that is often stressful and disrupting to an individual's daily routine.

Branched-chain amino acid, meat intake and risk of type 2 diabetes in the Women's Health Initiative. The British journal of nutrition, 117(11), 1523-1530.More infoKnowledge regarding association of dietary branched-chain amino acid (BCAA) and type 2 diabetes (T2D), and the contribution of BCAA from meat to the risk of T2D are scarce. We evaluated associations between dietary BCAA intake, meat intake, interaction between BCAA and meat intake and risk of T2D. Data analyses were performed for 74 155 participants aged 50-79 years at baseline from the Women's Health Initiative for up to 15 years of follow-up. We excluded from analysis participants with treated T2D, and factors potentially associated with T2D or missing covariate data. The BCAA and total meat intake was estimated from FFQ. Using Cox proportional hazards models, we assessed the relationship between BCAA intake, meat intake, and T2D, adjusting for confounders. A 20 % increment in total BCAA intake (g/d and %energy) was associated with a 7 % higher risk for T2D (hazard ratio (HR) 1·07; 95 % CI 1·05, 1·09). For total meat intake, a 20 % increment was associated with a 4 % higher risk of T2D (HR 1·04; 95 % CI 1·03, 1·05). The associations between BCAA intake and T2D were attenuated but remained significant after adjustment for total meat intake. These relations did not materially differ with or without adjustment for BMI. Our results suggest that dietary BCAA and meat intake are positively associated with T2D among postmenopausal women. The association of BCAA and diabetes risk was attenuated but remained positive after adjustment for meat intake suggesting that BCAA intake in part but not in full is contributing to the association of meat with T2D risk.

Nutrients in one-carbon metabolism and urinary arsenic methylation in the National Health and Nutrition Examination Survey (NHANES) 2003-2004. The Science of the total environment, 607-608, 381-390.More infoExposure to inorganic arsenic (inAs), a potent toxicant, occurs primarily through ingestion of food and water. The efficiency with which it is methylated to mono and dimethyl arsenicals (MMA and DMA) affects toxicity. Folate, vitamins B12 and B6 are required for 1C metabolism, and studies have found that higher levels of these nutrients increase methylation capacity and are associated with protection against adverse health effects from inAs, especially in undernourished populations. Our aim was to determine whether 1C-related nutrients are associated with greater inAs methylation capacity in a general population sample with overall adequate nutrition and low levels of As exposure. Univariate and multivariable regression models were used to evaluate the relationship of dietary and blood nutrients to urinary As methylation in the National Health and Nutrition Examination Survey (NHANES) 2003-2004. Outcome variables were the percent of the sum of inAs and methylated As species (inAs+MMA+DMA) excreted as inAs, MMA, and DMA, and the ratio of MMA:DMA. In univariate models, dietary folate, vitamin B6 and protein intake were associated with lower urinary inAs% and greater DMA% in adults (≥18years), with similar trends in children (6-18). In adjusted models, vitamin B6 intake (p=0.011) and RBC folate (p=0.036) were associated with lower inAs%, while dietary vitamin B12 was associated with higher inAs% (p=0.002) and lower DMA% (p=0.030). Total plasma homocysteine was associated with higher MMA% (p=0.004) and lower DMA% (p=0.003), but not with inAs%; other blood nutrients showed no association with urinary As. Although effect size is small, these findings suggest that 1C nutrients can influence inAs methylation and potentially play an indirect role in reducing toxicity in a general population sample.

While differences were not statistically significant, there were fewer breast cancers diagnosed in the low fat dietary group women (HR 0.92 95% CI 0.84-1.01, P=0.09) with somewhat lower breast cancer mortality (HR 0.77 95% CI 0.48-1.22) than seen in control group women (JAMA 2006; 295:629). These findings were recently updated, and after 10.9 years (mean) post-diagnosis follow-up, breast cancer overall survival among these 1,767 women measured from diagnosis was greater in the dietary group (10 year survival, 82% vs 78%, 168 (2.24%) versus 319 (2.71%) deaths; HR 0.80 95% CI 0.66-0.97, P=0.02) (AACR Annual Meeting 2016, abstract CT0433, Clinical Trials Plenary Session). We now report low-fat dietary pattern influence on breast cancer overall survival in subgroups defined by breast cancer characteristics. Methods: The WHI DM trial, conducted at 40 US clinical centers, from1993-1998 enrolled 48,835 postmenopausal women, aged 50-79, without prior breast cancer, with normal mammogram and dietary fat intake >32% of total energy. Participants were randomly assigned to a dietary intervention group (40%, n=19,541) with goals of fat intake reduction to 20% of energy and increased fruits, vegetables and grain intake, or a usual diet control group (60%, n=29,294). As previously reported, the dietary modification program reduced fat intake, increased fruit, vegetable and grain intake and was associated with modest weight loss (all P Results: The examined subgroups included histology (ductal, lobular, other), estrogen receptor (ER) status (positive vs. negative by local laboratory), progesterone receptor (PR) status, HER2 status, triple negative (yes/no), stage (local, regional or distant), grade (well, moderately, poorly differentiated), tumor size ( =2 cm), and nodal involvement (none, 1-3, 4+). None of the tests of interaction in subgroups were statistically significant. All subgroup hazard ratios (HR) were less than one except for ER negative cancers, triple negative cancers and those with 4+ positive lymph nodes. The results are suggestive of no influence of the low-fat dietary pattern on triple negative cancers (HR 1.64 95% CI 0.73-3.70 for triple negative vs. HR 0.73 95% CI 0.56-0.95 for other breast cancers, interaction P=0.06). Conclusion: Compared to a usual diet control group, women randomized to a dietary intervention group providing a low-fat dietary pattern had a significantly increased overall survival following a breast cancer diagnosis with the possible exception of those developing triple negative cancers.

Randomized phase III trial evaluating the role of weight loss in adjuvant treatment of overweight and obese women with early breast cancer (Alliance A011401): study design. NPJ breast cancer, 3, 37.More infoExcess body weight is a poor prognostic factor in women with early breast cancer, but the effect of weight loss on the risk of breast cancer recurrence and mortality in women who are overweight or obese at the time of breast cancer diagnosis has not been evaluated. The Alliance for Clinical Trials in Oncology Breast Cancer Weight Loss trial, also known as A011401, is testing the impact of a telephone-based weight loss program on invasive disease-free survival in 3136 women with a body mass index ≥27 kg/m2 who have recently been diagnosed with stage II-III, HER-2 negative breast cancer. Secondary outcomes of the trial include the impact of the weight loss intervention on overall survival, body weight, physical activity, dietary intakes, incidence of comorbidities, serum biomarkers and patient reported outcomes. Participants are randomized 1:1 to a 2-year, telephone-based weight loss intervention or to an education control group. The intervention is delivered through 42 telephone calls, delivered by health coaches based at the Dana-Farber Cancer Institute. Calls are supplemented by an intervention workbook, as well as a number of tools to help facilitate weight loss. Intervention goals include loss of 10% of baseline body weight, achieved through caloric restriction and increased physical activity. This large-scale study testing the impact of purposeful weight loss after cancer diagnosis on the risk of breast cancer recurrence and mortality has the potential to make weight loss programs a standard part of breast cancer treatment.

Intentional Weight Loss and Endometrial Cancer Risk. Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 35(11), 1189-1193.More infoPurpose Although obesity is an established endometrial cancer risk factor, information about the influence of weight loss on endometrial cancer risk in postmenopausal women is limited. Therefore, we evaluated associations among weight change by intentionality with endometrial cancer in the Women's Health Initiative (WHI) observational study. Patients and Methods Postmenopausal women (N = 36,794) ages 50 to 79 years at WHI enrollment had their body weights measured and body mass indices calculated at baseline and at year 3. Weight change during that period was categorized as follows: stable (change within ± 5%), loss (change ≥ 5%), and gain (change ≥ 5%). Weight loss intentionality was assessed via self-report at year 3; change was characterized as intentional or unintentional. During the subsequent 11.4 years (mean) of follow-up, 566 incident endometrial cancer occurrences were confirmed by medical record review. Multivariable Cox proportional hazards regression models were used to evaluate relationships (hazard ratios [HRs] and 95% CIs) between weight change and endometrial cancer incidence. Results In multivariable analyses, compared with women who had stable weight (± 5%), women with weight loss had a significantly lower endometrial cancer risk (HR, 0.71; 95% CI, 0.54 to 0.95). The association was strongest among obese women with intentional weight loss (HR, 0.44; 95% CI, 0.25 to 0.78). Weight gain (≥ 10 pounds) was associated with a higher endometrial cancer risk than was stable weight, especially among women who had never used hormones. Conclusion Intentional weight loss in postmenopausal women is associated with a lower endometrial cancer risk, especially among women with obesity. These findings should motivate programs for weight loss in obese postmenopausal women.

Circulating concentrations of biomarkers and metabolites related to vitamin status, one-carbon and the kynurenine pathways in US, Nordic, Asian, and Australian populations. The American journal of clinical nutrition, 105(6), 1314-1326.More infoBackground: Circulating concentrations of biomarkers that are related to vitamin status vary by factors such as diet, fortification, and supplement use. Published biomarker concentrations have also been influenced by the variation across laboratories, which complicates a comparison of results from different studies.Objective: We robustly and comprehensively assessed differences in biomarkers that are related to vitamin status across geographic regions.Design: The trial was a cross-sectional study in which we investigated 38 biomarkers that are related to vitamin status and one-carbon and tryptophan metabolism in serum and plasma from 5314 healthy control subjects representing 20 cohorts recruited from the United States, Nordic countries, Asia, and Australia, participating in the Lung Cancer Cohort Consortium. All samples were analyzed in a centralized laboratory.Results: Circulating concentrations of riboflavin, pyridoxal 5'-phosphate, folate, vitamin B-12, all-trans retinol, 25-hydroxyvitamin D, and α-tocopherol as well as combined vitamin scores that were based on these nutrients showed that the general B-vitamin concentration was highest in the United States and that the B vitamins and lipid soluble vitamins were low in Asians. Conversely, circulating concentrations of metabolites that are inversely related to B vitamins involved in the one-carbon and kynurenine pathways were high in Asians. The high B-vitamin concentration in the United States appears to be driven mainly by multivitamin-supplement users.Conclusions: The observed differences likely reflect the variation in intake of vitamins and, in particular, the widespread multivitamin-supplement use in the United States. The results provide valuable information about the differences in biomarker concentrations in populations across continents.

(2017). Low-fat dietary pattern and cardiovascular disease: results from the Women's Health Initiative randomized controlled trial. The American journal of clinical nutrition, 106(1), 35-43.More infoBackground: The influence of a low-fat dietary pattern on the cardiovascular health of postmenopausal women continues to be of public health interest.Objective: This report evaluates low-fat dietary pattern influences on cardiovascular disease (CVD) incidence and mortality during the intervention and postintervention phases of the Women's Health Initiative Dietary Modification Trial.Design: Participants comprised 48,835 postmenopausal women aged 50-79 y; 40% were randomly assigned to a low-fat dietary pattern intervention (target of 20% of energy from fat), and 60% were randomly assigned to a usual diet comparison group. The 8.3-y intervention period ended in March 2005, after which >80% of surviving participants consented to additional active follow-up through September 2010; all participants were followed for mortality through 2013. Breast and colorectal cancer were the primary trial outcomes, and coronary heart disease (CHD) and overall CVD were additional designated outcomes.Results: Incidence rates for CHD and total CVD did not differ between the intervention and comparison groups in either the intervention or postintervention period. However, CHD HRs comparing these groups varied strongly with baseline CVD and hypertension status. Participants without prior CVD had an intervention period CHD HR of 0.70 (95% CI: 0.56, 0.87) or 1.04 (95% CI: 0.90, 1.19) if they were normotensive or hypertensive, respectively (P-interaction = 0.003). The CHD benefit among healthy normotensive women was partially offset by an increase in ischemic stroke risk. Corresponding HRs in the postintervention period were close to null. Participants with CVD at baseline (3.4%) had CHD HRs of 1.47 (95% CI: 1.12, 1.93) and 1.61 (95% CI: 1.02, 2.55) in the intervention and postintervention periods, respectively. However, various lines of evidence suggest that results in women with CVD or hypertension at baseline are confounded by postrandomization use of cholesterol-lowering medications.Conclusions: CVD risk in postmenopausal women appears to be sensitive to a change to a low-fat dietary pattern and, among healthy women, includes both CHD benefit and stroke risk. This trial was registered at clinicaltrials.gov as NCT00000611.

Dietary Inflammatory Index and Risk of Colorectal Adenoma Recurrence: A Pooled Analysis. Nutrition and cancer, 1-10.More infoNo studies have evaluated the association between the dietary inflammatory index (DII) and colorectal adenoma recurrence. DII scores were calculated from a baseline food frequency questionnaire. Participants (n = 1727) were 40-80 years of age, enrolled in two Phase III clinical trials, who had ≥1 colorectal adenoma(s) removed within 6 months of study registration, and a follow-up colonoscopy during the trial. Multiple logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). No statistically significant associations were found between DII and odds of colorectal adenoma recurrence [ORs (95% CIs) = 0.93 (0.73, 1.18) and 0.95 (0.73, 1.22)] for subjects in the second and third DII tertiles, respectively, compared to those in the lowest tertile (Ptrend = 0.72). No associations were found for recurrent colorectal adenoma characteristics, including advanced recurrent adenomas, large size, villous histology, or anatomic location. While our study did not support an association between a proinflammatory diet and colorectal adenoma recurrence, future studies are warranted to elucidate the role of a proinflammatory diet on the early stages of colorectal carcinogenesis.

Abstract P3-02-03: Accurate and reliable automated breast density measurements with no ionizing radiation using fat-water decomposition MRI. Cancer Research, 77. doi:10.1158/1538-7445.sabcs16-p3-02-03More infoObjective Breast density(BD) is a measure of the distribution of variable tissue types within the breast and higher BD has been shown to positively correlate with breast cancer risk. As such, the accurate measurement of BD has become a priority for risk assessment and for evaluating the effects of prevention strategies aimed at reducing BD. Mammography(MG) is the most common method of BD determination but is limited by the exposure to ionizing radiation, particularly for studies requiring repeated measures. BD derived from fat-water decomposition magnetic resonance imaging(FWMRI-BD) has been proposed as an alternative, safe, and quantitative method for BD. To optimize its use, we developed a new FWMRI-BD that is automated, more accurate and reliable. In this study, we compare our automated method to digital MG and a previous reported algorithm for MRI derived BD. Methods From a completed prevention trial, 42 pre- and post-menopausal patients receiving tamoxifen therapy for early stage breast cancer or as primary chemoprevention were identified. Patients had undergone prior digital MG within 6 months from the date of MRI scan and MG-BD was calculated using a well-established method(Cumulus). MRI scans were performed on a 1.5T GE Signa NV-CV/i scanner using an axial radial IDEAL-GRASE sequence to generate quantitative fat fraction maps of the entire breast. Total acquisition time was Results Table 1 shows the correlation and reliability analysis results between MG-BD and FWMRI-BD. Both FWMRI-BD measures(Fra80 and FraG+W) were strongly correlated with MG-BD. More importantly, they exhibit superior test-retest reliability(ICC>0.98) compared to MG-BD values from the literature(reported ICC range 0.91-0.95). FraG+W showed improvement over Fra80 in all measures tested including correlation to MG-BD, dynamic range, standard errors and ICC. Conclusion The refined and automated FWMRI-BD that quantifies the entire fibroglandular and water content of the breast(FraG+W) strongly correlates with MG-BD and is more accurate and reliable than previous FWMRI-BD method.

International journal of cancer.More infoCirculating vitamin B6 levels have been found to be inversely associated with lung cancer. Most studies have focused on the B6 form pyridoxal 5'-phosphate (PLP), a direct biomarker influenced by inflammation and other factors. Using a functional B6 marker allows further investigation of the potential role of vitamin B6 status in the pathogenesis of lung cancer. We prospectively evaluated the association of the functional marker of vitamin B6 status, the 3-hydroxykynurenine:xanthurenic acid (HK:XA) ratio, with risk of lung cancer in a nested case-control study consisting of 5,364 matched case-control pairs from the Lung Cancer Cohort Consortium (LC3). We used conditional logistic regression to evaluate the association between HK:XA and lung cancer, and random effect models to combine results from different cohorts and regions. High levels of HK:XA, indicating impaired functional B6 status, were associated with an increased risk of lung cancer, the odds ratio comparing the fourth and the first quartiles (OR4thvs.1st ) was 1.25 (95% confidence interval, 1.10-1.41). Stratified analyses indicated that this association was primarily driven by cases diagnosed with squamous cell carcinoma. Notably, the risk associated with HK:XA was approximately 50% higher in groups with a high relative frequency of squamous cell carcinoma, i.e., men, former and current smokers. This risk of squamous cell carcinoma was present in both men and women regardless of smoking status.

Factors Associated With New-Onset Depression Following Ischemic Stroke: The Women's Health Initiative.. Journal of the American Heart Association, 6(2). doi:10.1161/jaha.116.003828More infoPsychosocial characteristics have a strong effect on risk of depression, and their direct treatment with behavioral interventions reduces rates of depression. Because new-onset poststroke depression (NPSD) is frequent, devastating, and often treatment-resistant, novel preventive efforts are needed. As a first step toward developing behavioral interventions for NPSD, we investigated whether prestroke psychosocial factors influenced rates of NPSD in a manner similar to the general population..Using the Women's Health Initiative, we analyzed 1424 respondents who were stroke-free at enrollment and had no self-reported history of depression from enrollment to their nonfatal ischemic stroke based on initiation of treatment for depression or the Burnam screening instrument for detecting depressive disorders. NPSD was assessed using the same method during the 5-year poststroke period. Logistic regression provided odds ratios of NPSD controlling for multiple covariates. NPSD occurred in 21.4% (305/1424) of the analytic cohort and varied by stroke severity as measured by the Glasgow scale, ranging from 16.7% of those with good recovery to 31.6% of those severely disabled. Women with total anterior circulation infarction had the highest level (31.4%) of NPSD while those with lacunar infarction had the lowest (16.1%). Prestroke psychosocial measures had different associations with NPSD depending on functional recovery of the individual..There is a difference in the relationship of prestroke psychosocial status and risk of NPSD depending on stroke severity; thus it may be that the same preventive interventions might not work for all stroke patients. One size does not fit all.

Cancer Research, 77, 5311-5311. doi:10.1158/1538-7445.am2017-5311More infoBody fatness is an established risk factor for postmenopausal breast cancer, but it is unknown if this risk associated with excess body weight is reversible. We conducted a pooled analysis of 11 prospective studies in the Pooling Project of Prospective Studies of Diet and Cancer. Each study had adult body weight data at three time points, as well as follow-up for subsequent risk of breast cancer after the third weight measure. Weight change was assessed using reported or measured weight at baseline and two follow-up time points, each generally four to six years apart (over a total of ~10 years). Stable weight for each interval was defined as weight within 2kg of the previous weight. The referent group was women with stable weight (within 2kg) at all three time points across the 10-year period. Among 340,055 women, 10,427 breast cancers were diagnosed during follow-up. Multivariable hazard ratios (HR) and 95% confidence intervals (CI) controlling for baseline body mass index (BMI), baseline physical activity, and postmenopausal hormone (PMH) use at the start of breast cancer follow-up, were estimated using proportional hazards regression on an aggregated dataset from all studies. Women who lost weight and kept the weight off, were at a lower risk of breast cancer than women with stable weight over the 10 years: >2.-4.5kg lost between baseline and the first follow-up body weight measure (n=482 cases): HR=0.92, 95% CI: 0.83-1.03; >4.5-9kg lost (n=283 cases): HR=0.86, 95% CI: 0.76-0.98; >9kg lost (n=95 cases): HR =0.81, 95%CI: 0.65-1.00). Women who initially lost weight (>2kg), but then re-gained it had a similar risk of breast cancer to those with stable weight over the same time period. When results were stratified by baseline age and BMI, there was no association between sustained weight loss and breast cancer among women younger than 50 years, nor those with a normal BMI (18.5-25 kg/m2) before weight loss. Among women who were aged 50 or more years and overweight or obese before the weight loss period, we observed a 21% lower risk of breast cancer for sustained weight loss of ≥4.5kg compared to women with stable weight over the same time period (n=245 cases, HR=0.79, 95% CI: 0.68-0.93). This observed association was driven by women who were not taking PMH (n=156, HR=0.71, 95% CI: 0.58-0.86). In this large, pooled prospective analysis of weight loss and breast cancer risk we found that losing 4.5 kg—and keeping it off—may lower breast cancer risk, particularly for women older than 50 who are overweight or obese. The results may provide motivation for women with elevated BMI to lose weight and potentially reduce their risk of breast cancer. Citation Format: Lauren R. Teras, Alpa V. Patel, Molin Wang, Bette J.

Practical clinical interventions for diet, physical activity, and weight control in cancer survivors. CA: a cancer journal for clinicians, 65(3), 167-89.More infoAnswer questions and earn CME/CNE The importance of expanding cancer treatment to include the promotion of overall long-term health is emphasized in the Institute of Medicine report on delivering quality oncology care. Weight management, physical activity, and a healthy diet are key components of tertiary prevention but may be areas in which the oncologist and/or the oncology care team may be less familiar. This article reviews current diet and physical activity guidelines, the evidence supporting those recommendations, and provides an overview of practical interventions that have resulted in favorable improvements in lifestyle behavior change in cancer survivors. It also describes current lifestyle practices among cancer survivors and the role of the oncologist in helping cancer patients and survivors embark upon changes in lifestyle behaviors, and it calls for the development of partnerships between oncology providers, primary care providers, and experts in nutrition, exercise science, and behavior change to help positively orient cancer patients toward longer and healthier lives.

Phase II study of metformin for reduction of obesity-associated breast cancer risk: a randomized controlled trial protocol. BMC Cancer, 16, 500.More infoTwo-thirds of U.S. adult women are overweight or obese. High body mass index (BMI) and adult weight gain are risk factors for a number of chronic diseases, including postmenopausal breast cancer. The higher postmenopausal breast cancer risk in women with elevated BMI is likely to be attributable to related metabolic disturbances including altered circulating sex steroid hormones and adipokines, elevated pro-inflammatory cytokines, and insulin resistance. Metformin is a widely used antidiabetic drug that has demonstrated favorable effects on metabolic disturbances and as such may lead to lower breast cancer risk in obese women. Further, the anti-proliferative effects of metformin suggest it may decrease breast density, an accepted biomarker of breast cancer risk.

Cancer Research, 76. doi:10.1158/1538-7445.am2016-ct043More infoProceedings: AACR 107th Annual Meeting 2016; April 16-20, 2016; New Orleans, LA Context: The Women's Health Initiative Dietary Modification trial randomized 48,835 postmenopausal women at 40 US clinical centers from 1993 to 1998. With 1,767 incident breast cancers, during 8.3 years (mean) dietary intervention, there were fewer breast cancers in the dietary group (HR 0.92 95% CI 0.84-1.01, P = 0.09) with somewhat fewer deaths from breast cancer (HR 0.77 95% CI 0.48-1.22), but no apparent post-intervention influence (JAMA 2006; 295:629; Cancer Epi Bio Prev 2014; 23:2924). These findings suggested dietary intervention may reduce breast cancers associated with greater mortality. New information on breast cancer mortality is analyzed here. Objective: To examine low-fat dietary pattern influence on breast cancer mortality for cases diagnosed during the dietary intervention period. Design and Setting: Secondary analyses from a randomized controlled dietary modification trial. Participants: 48,835 postmenopausal women, 50 to 79 years old, with no previous breast or colorectal cancer, with dietary fat intake greater than 32% of total energy and with a mammogram not suspicious for cancer at entry. I nterventions: Dietary group (40%, n = 19,541) which included nutritionist led group sessions throughout the 8.3 year (mean) dietary intervention. Usual diet control group participants received diet-related education materials (60%, n = 29,294). Main Outcome Measures: Deaths from breast cancer (breast cancer followed by deaths directly attributed to the cancer) and deaths after breast cancer (breast cancer followed by death from any cause) during 8.3 years (mean) dietary intervention including all 48,835 study participants measured from randomization. Secondarily, breast cancer overall survival (survival from diagnosis with death from any cause) for the 1767 breast cancer cases identified during the dietary intervention period and followed through August, 2014. Results: Baseline demographic characteristics and breast cancer risk factors were closely comparable in the two randomization groups as was screening mammography frequency throughout. In the dietary group, fat intake decreased, vegetable, fruit and grain consumption increased and body weight was modestly reduced (all P

Contemporary clinical trials, 49, 181-9.More infoOvarian cancer is the most common cause of gynecological cancer death in United States women. Efforts to improve progression free survival (PFS) and quality of life (QoL) after treatment for ovarian cancer are necessary. Observational studies suggest that lifestyle behaviors, including diet and physical activity, are associated with lower mortality in this population. The Lifestyle Intervention for Ovarian Cancer Enhanced Survival (LIVES) NRG 0225 study is a randomized, controlled trial designed to test the hypothesis that a 24month lifestyle intervention will significantly increase PFS after oncological therapy for stage II-IV ovarian cancer. Women are randomized 1:1 to a high vegetable and fiber, low-fat diet with daily physical activity goals or an attention control group. Secondary outcomes to be evaluated include QoL and gastrointestinal health. Moreover an a priori lifestyle adherence score will be used to evaluate relationships between adoption of the diet and activity goals and PFS. Blood specimens are collected at baseline, 6, 12 and 24months for analysis of dietary adherence (carotenoids) in addition to mechanistic biomarkers (lipids, insulin, telomere length). Women are enrolled at NRG clinic sites nationally and the telephone based lifestyle intervention is delivered from The University of Arizona call center by trained health coaches. A study specific multi-modal telephone, email, and SMS behavior change software platform is utilized for information delivery, coaching and data capture. When completed, LIVES will be the largest behavior-based lifestyle intervention trial conducted among ovarian cancer survivors.

Nutrition reviews, 74(7), 432-43.More infoDiet is a modifiable factor associated with the risk of several cancers, with convincing evidence showing a link between diet and breast cancer. The role of bioactive compounds of food origin, including those found in cruciferous vegetables, is an active area of research in cancer chemoprevention. This review focuses on 3,3'-diindolylmethane (DIM), the major bioactive indole in crucifers. Research of the cancer-preventive activity of DIM has yielded basic mechanistic, animal, and human trial data. Further, this body of evidence is largely supported by observational studies. Bioactive DIM has demonstrated chemopreventive activity in all stages of breast cancer carcinogenesis. This review describes current evidence related to the metabolism and mechanisms of DIM involved in the prevention of breast cancer. Importantly, this review also focuses on current evidence from human observational and intervention trials that have contributed to a greater understanding of exposure estimates that will inform recommendations for DIM intake.

Maternal and child health journal, 20(3), 525-33. doi:10.1007/s10995-015-1850-7More infoThis article reports on a formative assessment with Latino mothers in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) evaluating knowledge, attitudes and behaviors regarding healthy growth for infants and their understanding of infant growth monitoring. Further, we explored the acceptability and feasibility of mothers' monitoring their infants' growth. This assessment includes healthy growth perceptions from mothers, caregivers and from WIC staff..Utilizing a mixed method approach, this assessment included qualitative focus groups with WIC mothers that included a growth chart plotting exercise and a quantitative survey. In-depth interviews with clinic staff discussing protocols used in assessing children's growth were also conducted in one WIC clinic..Focus group participants included 34 mothers and 19 caregivers with a mean age of 32 years; 90 % identified as Latino. Themes included concern for underweight status, and reports of limited conversations between mothers and healthcare providers regarding overweight status, and infant feeding practices/beliefs that may contribute to feeding behaviors associated with risk for excess weight gain during infancy. Growth charts were well received, mothers were able to plot with modest accuracy; but effectiveness of growth plotting might be limited without refinement for health literacy and the provision of culturally-sensitive education in relation to feeding behaviors to support healthy infant growth..This represents a first effort in evaluating Latino mothers' perceptions of infants' healthy growth and use growth charts as a potential tool that can help prevent excess weight gain in early infancy.

Risk of Mortality According to Body Mass Index and Body Composition Among Postmenopausal Women. American journal of epidemiology, 182(7), 585-96.More infoObesity, often defined as a body mass index (BMI; weight (kg)/height (m)(2)) of 30 or higher, has been associated with mortality, but age-related body composition changes can be masked by stable BMI. A subset of Women's Health Initiative participants (postmenopausal women aged 50-79 years) enrolled between 1993 and 1998 who had received dual-energy x-ray absorptiometry scans for estimation of total body fat (TBF) and lean body mass (LBM) (n = 10,525) were followed for 13.6 (standard deviation, 4.6) years to test associations between BMI, body composition, and incident mortality. Overall, BMI ≥35 was associated with increased mortality (adjusted hazard ratio (HR) = 1.45, 95% confidence interval (CI): 1.16, 1.82), while TBF and LBM were not. However, an interaction between age and body composition (P < 0.001) necessitated age stratification. Among women aged 50-59 years, higher %TBF increased risk of death (HR = 2.44, 95% CI: 1.38, 4.34) and higher %LBM decreased risk of death (HR = 0.41, 95% CI: 0.23, 0.74), despite broad-ranging BMIs (16.4-69.1). However, the relationships were reversed among women aged 70-79 years (P < 0.05). BMI did not adequately capture mortality risk in this sample of postmenopausal women. Our data suggest the clinical utility of evaluating body composition by age group to more robustly assess mortality risk among postmenopausal women.

Mediation of Weight Loss and Weight Loss Maintenance through Dietary Disinhibition and Restraint. Journal of obesity & weight loss therapy, 5(2).More infoUnderstanding the degree to which eating behaviors, such as disinhibition and restraint, are associated with weight loss and weight loss maintenance could contribute to further refinement of effective weight management intervention strategies. The purpose of this analysis was to examine if these factors mediate weight loss or weight loss maintenance using data from a randomized controlled trial testing a commercial weight loss program that delivered behavioral counseling and structured meal plans including prepackaged foods. Mediation analyses were used to examine whether changes in disinhibition and restraint mediated the relationship between intervention and weight change during initial weight loss (0-6 months), continued weight loss (6-12 months), or weight loss maintenance (12-24 months) phases. Only decreases in disinhibition between baseline and 6 months mediated the intervention effect on initial weight loss. Our results suggest the mediation effects of these eating behaviors are modest and other factors contribute to a larger, more complex long-term weight loss prognosis.

Abstract P6-01-18: 2-Hydroxyestrone is associated with breast density measured by mammography and fat:water ratio magnetic resonance imaging in women taking tamoxifen. Cancer Research, 75. doi:10.1158/1538-7445.sabcs14-p6-01-18More infoResearch Objectives and Rationale. Tamoxifen (TAM) use has been shown to reduce breast cancer recurrence with the benefit greater in patients who experience a TAM-associated decrease in percent mammographic density(PMD); findings that support PMD as a biomarker of response to TAM. PMD is a radiographic phenomenon of breast fibroglandular tissue that is associated with breast cancer risk. PMD is inversely associated with body mass index (BMI) and sparse data have shown a weak positive association with the sex hormone levels. Limited data exist evaluating the relationship between TAM, 2OHE1:16 a-OHE1 ratio (concentrations previously hypothesized to be associated with a reduced risk of breast cancer) and PBD. Methods. Using cross-sectional baseline breast density (BD) from an ongoing prevention trial of diindolylmethane (DIM) in 121 women receiving TAM, we evaluated BD in relation to circulating TAM metabolites [TAM, endoxifen, 4-OH TAM, ND TAM], estradiol (E2), sex hormone-binding globulin (SHBG) and urinary 2-OHE1 and 16α-OHE1. PMD was assessed by mammography (n=65; 54%) and also a novel, non-radiative, non-contrast magnetic resonance imaging-derived fat-water ratio (FWR-MRI) as the fat fraction (Fra)50 and 80 (n=53; 44%) developed for repeat BD assessment in short intervals. This is our first report that BD using digitized mammograms is correlated with FWR-MRI-derived measures designated Fra50 and Fra80; Spearman ρ = 0.90 and 0.86, respectively, p Results. As previously demonstrated, BMI was inversely correlated with all measures of BD. No association was shown between TAM and TAM metabolites and BD or urinary 2OHE1. Further, we found no relationship between circulating E2 or SHBG concentrations and BD. In contrast, urinary 2OHE1 levels were positively correlated with BD across all measures of density; 2OHE1 levels were most strongly correlated with BD measured by FW-MRI using Fra80 (Spearman ρFra80=0.483; p=0.001 compared to ρFra50 =0.431; p = 0.004 and ρPD=0.400; p=0.003). A significant, but weaker, correlation was observed for the 2OHE1:16OHE1 ratio and BD (ρ values 0.34-0.38). The magnitude of the relationship between 2OHE1 and BD was similar in pre and post-menopausal women despite lower PBD after menopause. Conclusions. Our results replicate earlier work from Maskarinec et al. wherein excreted 2OHE1 was an independent determinant of BD. These data challenge the hypothesis proposed by Yager and Liehr that higher urinary 2OHE1 to 16OHE1 ratio would be indicative of reduced hormone tumorigenesis. These results suggest a possible comparable binding affinity for the estrogen receptor that may modify endogenous steroid hormones and their effects on BD. Our findings strengthen the arguments favoring a better mechanistic understanding of BD, the biological determinants and their relationship to breast cancer. This is particularly timely given new mandates to provide BD measures to all women undergoing mammography and recent findings that while BD is associated with breast cancer risk high BD is not associated with greater breast cancer mortality.

Red blood cell folate and plasma folate are not associated with risk of incident colorectal cancer in the Women's Health Initiative observational study. International journal of cancer. Journal international du cancer, 137(4), 930-9.More infoThe relationship between folate and colorectal cancer (CRC) risk is unclear. We investigated the association of two biomarkers of folate status, plasma folate and red blood cell (RBC) folate, with CRC risk using a nested case-control design in the Women's Health Initiative Observational Study. Postmenopausal women (n = 93,676) aged 50-79 years were enrolled in the Women's Health Initiative Observational Study (1993-1998). A fasting blood draw and extensive health, dietary and lifestyle data were collected upon enrollment. Through 2008, 988 incident CRC cases were reported and confirmed with medical records adjudication. Cases and controls were matched on age (± 3 years), enrollment date (± 1 year), race/ethnicity, blood draw date (± 6 months) and hysterectomy status. Plasma and RBC folate were determined by radio assay. Folate biomarker values were divided into quartiles, and conditional logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CI) for the associations of folate with total CRC, by tumor site and by stage at diagnosis. Additional analyses examined whether risks varied across time periods corresponding to the United States folic acid fortification policy: prefortification (1994-1995), perifortification (1996-1997) and postfortification (1998). ORs for overall CRC risk comparing Q4 vs. Q1 were 0.91 (95% CI 0.67-1.24) and 0.91 (95% CI 0.67-1.23) for RBC and plasma folate, respectively. There were no changes in risk attributable to food supply fortification. These results do not support an overall association of folate with CRC risk and suggest that folic acid fortification of the US food supply did not alter the associations in these postmenopausal women.

Advances in nutrition (Bethesda, Md.), 6(6), 763-73.More infoColorectal cancer (CRC) is the third most common cancer in both men and women in the United States. Various a priori dietary patterns that take into account diet complexity have been associated with CRC risk. This systematic review augments the evidence for an association between CRC risk and the Mediterranean Diet Score (MDS) and the Healthy Eating Index (HEI), and provides new evidence for a novel Dietary Inflammatory Index (DII). Human studies published in English after 31 December 2008 were reviewed. Five case-control studies and 7 prospective cohort studies conducted in the United States and Europe were identified. Five of the studies examined the MDS, 4 examined the HEI, and 4 examined the DII. Comparing highest to lowest score groups, higher MDSs were associated with an 8-54% lower CRC risk, and higher HEI scores were associated with a 20-56% lower CRC risk. More proinflammatory diet scores were associated with a 12-65% higher CRC risk compared with more anti-inflammatory diets in studies that used the DII. The results reported by sex suggested similar associations for men and women. This review builds upon the evidence supporting the association between higher overall diet quality and lower risk of CRC. Increasing scores of MDS and HEI and anti-inflammatory DII scores are characterized by high intake of plant-based foods and low intake of animal products. Future studies in more diverse populations and with consistent scoring calculations are recommended.

Maternal and child health journal.More infoObjectives This article reports on a formative assessment with Latino mothers in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) evaluating knowledge, attitudes and behaviors regarding healthy growth for infants and their understanding of infant growth monitoring. Further, we explored the acceptability and feasibility of mothers' monitoring their infants' growth. This assessment includes healthy growth perceptions from mothers, caregivers and from WIC staff. Methods Utilizing a mixed method approach, this assessment included qualitative focus groups with WIC mothers that included a growth chart plotting exercise and a quantitative survey. In-depth interviews with clinic staff discussing protocols used in assessing children's growth were also conducted in one WIC clinic. Results Focus group participants included 34 mothers and 19 caregivers with a mean age of 32 years; 90 % identified as Latino. Themes included concern for underweight status, and reports of limited conversations between mothers and healthcare providers regarding overweight status, and infant feeding practices/beliefs that may contribute to feeding behaviors associated with risk for excess weight gain during infancy. Growth charts were well received, mothers were able to plot with modest accuracy; but effectiveness of growth plotting might be limited without refinement for health literacy and the provision of culturally-sensitive education in relation to feeding behaviors to support healthy infant growth. Conclusions This represents a first effort in evaluating Latino mothers' perceptions of infants' healthy growth and use growth charts as a potential tool that can help prevent excess weight gain in early infancy.

Cancer causes & control : CCC, 26(12), 1761-9. doi:10.1007/s10552-015-0669-2More infoData relating to magnesium intake and colorectal cancer (CRC) risk in postmenopausal women are incomplete. We investigated the association between total magnesium intake and the risk of CRC in an ethnically diverse cohort of postmenopausal women enrolled in the Women's Health Initiative..Self-reported dietary and supplemental magnesium were combined to form total magnesium intake. Invasive incident CRC was the primary outcome. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI)..During an average follow-up of 13 years (1,832,319 person-years), of the 140,601 women included for analysis, 2,381 women were diagnosed with CRC (1,982 colon cancer and 438 rectal cancer). After adjustment for potential confounding variables, an inverse association was observed in the highest quintile of total magnesium intake compared to the lowest quintile for risk of CRC (HR 0.79, 95% CI 0.67, 0.94, p trend < 0.0001) and colon cancer (HR 0.80, 95% CI 0.66, 0.97, p trend < 0.0001). A borderline significant inverse association was detected in the highest versus the lowest quintile of total magnesium intake for rectal cancer (HR 0.76, 95% CI 0.51, 1.13, p trend < 0.001)..Findings from this study support the hypothesis that magnesium intake around 400 mg/day from both dietary and supplemental sources is associated with a lower incidence of CRC in postmenopausal women.

Journal of the Academy of Nutrition and Dietetics, 114(7), 1036-45.More infoDiet quality has not been well studied in relation to positive psychological traits. Our purpose was to investigate the relationship between optimism and diet quality in postmenopausal women enrolled in the Women's Health Initiative observational study (OS) and clinical trials (CTs), and to determine whether optimism was associated with diet change after a 1-year dietary intervention. Diet quality was scored with the Alternate Healthy Eating Index (AHEI) and optimism assessed with the Life Orientation Test-Revised. Baseline characteristics were compared across AHEI quintiles or optimism tertiles using regression models with each variable of interest as a function of quintiles or tertiles (OS, n=87,630; CT, n=65,360). Association between optimism and baseline AHEI and change in AHEI over 1 year were tested using multivariate linear regression (CT, n=13,645). Potential interaction between optimism and trial arm and demographic/lifestyle factors on AHEI change was tested using likelihood ratio test (CT intervention, n=13,645; CT control, n=20,242). Women reporting high AHEI were non-Hispanic white, educated, physically active, past or never smokers, hormone therapy users, had lower body mass index and waist circumference, and were less likely to have chronic conditions. In the CT intervention, higher optimism was associated with higher AHEI at baseline and with greater change over 1 year (P=0.001). Effect modification by intervention status was observed (P=0.014), whereas control participants with highest optimism achieved threefold greater AHEI increase compared with those with the lowest optimism. These data support a relationship between optimism and dietary quality score in postmenopausal women at baseline and over 1 year.

Obstetrical & Gynecological Survey, 69(2), 83-85. doi:10.1097/01.ogx.0000444679.66386.38More infoRESULTS During the CEE plus MPA intervention phase, the numbers of CHD cases were 196 for CEE plus MPA vs 159 for placebo (hazard ratio [HR], 1.18; 95% CI, 0.95-1.45) and 206 vs 155, respectively, for invasive breast cancer (HR, 1.24; 95% CI, 1.01-1.53). Other risks included increased stroke, pulmonary embolism, dementia (in women aged65 years), gallbladder disease, and urinary incontinence; benefits included decreased hip fractures, diabetes, and vasomotor symptoms. Most risks and benefits dissipated postintervention, although some elevation in breast cancer risk persisted during cumulative follow-up (434 cases for CEE plus MPA vs 323 for placebo; HR, 1.28 [95% CI, 1.11-1.48]). The risks and benefits were more balanced during the CEE alone intervention with 204 CHD cases for CEE alone vs 222 cases for placebo (HR, 0.94; 95% CI, 0.781.14) and 104 vs 135, respectively, for invasive breast cancer (HR, 0.79; 95% CI, 0.61-1.02); cumulatively, there were 168 vs 216, respectively, cases of breast cancer diagnosed (HR, 0.79; 95% CI, 0.65-0.97). Results for other outcomes were similar to CEE plus MPA. Neither regimen affected all-cause mortality. For CEE alone, younger women (aged 50-59 years) had more favorable results for all-cause mortality, myocardial infarction, and the global index (nominal P < .05 for trend by age). Absolute risks of adverse events (measured by the global index) per 10 000 women annually taking CEE plus MPA ranged from 12 excess cases for ages of 50-59 years to 38 for ages of 70-79 years; for women taking CEE alone, from 19 fewer cases for ages of 50-59 years to 51 excess cases for ages of 70-79 years. Quality-of-life outcomes had mixed results in both trials. CONCLUSIONS AND RELEVANCE Menopausal hormone therapy has a complex pattern of risks and benefits. Findings from the intervention and extended postintervention follow-up of the 2 WHI hormone therapy trials do not support use of this therapy for chronic disease prevention, although it is appropriate for symptom management in some women.

There is a need to identify modifiable dietary risk factors for this disease. To evaluate the role of diet in ovarian cancer risk, we performed a PRISMA-directed systematic review that included prospective cohort studies with >200 cases (n = 24). Higher risk for ovarian cancer was shown for total, animal, and dairy fat (five of nine studies), as well as total nitrate and possibly total vitamin C. No associations were demonstrated for red meat, fiber, vitamin A, vitamin E, β-carotene, or folate. Vegetables were associated with lower risk in one of three studies; fruit showed no association, although risk estimates were all greater than 1.0. Isoflavones and flavonoids were associated with modestly lower risk in two studies and tea intake was associated with lower risk in one of two studies. This review suggests that no specific dietary factors are consistently associated with ovarian cancer risk. Data by tumor subtypes are limited, but suggest that differential associations by tumor subtype may exist and should be evaluated. Studies of ample sample size, varied exposure, which can better control for dietary measurement error, are needed to fully define dietary recommendations for ovarian cancer prevention.

Cancer prevention research (Philadelphia, Pa.), 7(1).More infoHealthy lifestyle behaviors are recommended to reduce cancer risk and overall mortality. Adherence to cancer-preventive health behaviors and subsequent cancer risk has not been evaluated in a diverse sample of postmenopausal women. We examined the association between the American Cancer Society (ACS) Nutrition and Physical Activity Cancer Prevention Guidelines score and risk of incident cancer, cancer-specific mortality, and all-cause mortality in 65,838 postmenopausal women enrolled in the Women's Health Initiative Observational Study. ACS guidelines scores (0-8 points) were determined from a combined measure of diet, physical activity, body mass index (current and at age 18 years), and alcohol consumption. After a mean follow-up of 12.6 years, 8,632 incident cancers and 2,356 cancer deaths were identified. The highest ACS guidelines scores compared with the lowest were associated with a 17% lower risk of any cancer [HR, 0.83; 95% confidence interval (CI), 0.75-0.92], 22% lower risk of breast cancer (HR, 0.78; 95% CI, 0.67-0.92), 52% lower risk of colorectal cancer (HR, 0.48; 95% CI, 0.32-0.73), 27% lower risk of all-cause mortality, and 20% lower risk of cancer-specific mortality (HR, 0.80; 95% CI, 0.71-0.90). Associations with lower cancer incidence and mortality were generally strongest among Asian, black, and Hispanic women and weakest among non-Hispanic whites. Behaviors concordant with Nutrition and Physical Activity Cancer Prevention Guidelines were associated with lower risk of total, breast, and colorectal cancers and lower cancer-specific mortality in postmenopausal women.

Nutrition and cancer, 66(7), 1144-53.More infoDietary polyamines have recently been associated with increased risk of pre-malignant colorectal lesions. Because polyamines are synthesized in cells and taken up from dietary sources, development of a biomarker of exposure is challenging. Excess polyamines are primarily excreted in the urine. This pilot study seeks to identify dietary correlates of excreted urinary polyamines as putative biomarkers of exposure. Dietary polyamines/other nutrients were estimated from a food frequency questionnaire (FFQ) and correlated with urinary levels of acetylated polyamines in 36 men using 24-h urine samples. Polyamines, abundant in cheese and citrus, were highly positively correlated with urinary N(8)-acetylspermidine (correlation coefficient; r = 0.37, P = 0.03), but this correlation was attenuated after adjustment for total energy intake (r = 0.07, P = 0.68). Dietary energy intake itself was positively correlated with urinary total acetylated polyamine output (r = .40, P = 0.02). In energy-adjusted analyses, folic acid and folate from food were associated with urinary N(1),N(12)-diacetylspermine (r = 0.34, P = 0.05 and r = -0.39, P = 0.02, respectively). Red meat negatively correlated with total urinary acetylated polyamines (r = -0.42, P = 0.01). Our findings suggest that energy, folate, folic acid, saturated fat, and red meat intake, as opposed to FFQ-estimated dietary polyamines, are correlated with urinary polyamines.

Journal of Functional Foods, 11, 500-508. doi:10.1016/j.jff.2014.08.005More infoSweet cherries are rich in bioactive anthocyanins (ACN) and thus are considered a functional food. Yet, tolerance to and bioavailability of a significant daily dose of cherries has not been evaluated in humans. This pilot study aimed to assess compliance, tolerance, safety, and change in circulating/excreted ACNs due to daily consumption of sweet cherries. Change in bowel habits, quality of life, urinary/circulating concentration ACNs, and inflammatory biomarkers were measured in overweight, older men (n = 37) before and after daily consumption of three cups of sweet cherries for 4 weeks. Cherry fruit ACN content was also measured. Tolerance to intervention was high in this study. An increase in several plasma/urine ACNs was observed, but did not correlate with the amount of ACN measured in the fruits. No significant changes in inflammatory biomarkers were observed. This intervention was feasible and increased anthocyanin exposure in overweight men.

The majority of these studies are conducted in young adults. This analysis in a large (n = 769) sample of postmenopausal women (median age 63 years) sought to (a) confirm that sleep duration and sleep quality are negatively correlated with circulating leptin concentrations and (b) to examine the relationship between self-reported sleep, dietary energy intake, and diet quality, as well as, investigate the role of leptin in these associations..Sleep duration/quality, insomnia, and dietary intake were determined via self-report. Blood samples were collected following an overnight fast to assess serum leptin concentration. All analyses were adjusted for total body fat mass..Women reporting ≤6 hr sleep/night had lower serum leptin concentrations than those reporting ≥8 hr sleep (P = 0.04). Furthermore, those with ≤6 hr sleep/night reported higher dietary energy intake (P = 0.01) and lower diet quality (P = 0.04) than the reference group (7 hr sleep/night). Women sleeping ≥8 hr also reported lower diet quality than the reference group (P = 0.02). Importantly, serum leptin did not confound these associations..These results provide evidence that sleep duration is inversely associated with serum leptin and dietary energy intake in postmenopausal women.

(2014). Simultaneous association of total energy consumption and activity-related energy expenditure with risks of cardiovascular disease, cancer, and diabetes among postmenopausal women. American journal of epidemiology, 180(5), 526-35.More infoTotal energy consumption and activity-related energy expenditure (AREE) estimates that have been calibrated using biomarkers to correct for measurement error were simultaneously associated with the risks of cardiovascular disease, cancer, and diabetes among postmenopausal women who were enrolled in the Women's Health Initiative at 40 US clinical centers and followed from 1994 to the present. Calibrated energy consumption was found to be positively related, and AREE inversely related, to the risks of various cardiovascular diseases, cancers, and diabetes. These associations were not evident in most corresponding analyses that did not correct for measurement error. However, an important analytical caveat relates to the role of body mass index (BMI) (weight (kg)/height (m)(2)). In the calibrated variable analyses, BMI was regarded, along with self-reported data, as a source of information on energy consumption and physical activity, and BMI was otherwise excluded from the disease risk models. This approach cannot be fully justified with available data, and the analyses herein imply a need for improved dietary and physical activity assessment methods and for longitudinal self-reported and biomarker data to test and relax modeling assumptions. Estimated hazard ratios for 20% increases in total energy consumption and AREE, respectively, were as follows: 1.49 (95% confidence interval: 1.18, 1.88) and 0.80 (95% confidence interval: 0.69, 0.92) for total cardiovascular disease; 1.43 (95% confidence interval: 1.17, 1.73) and 0.84 (95% confidence interval: 0.73, 0.96) for total invasive cancer; and 4.17 (95% confidence interval: 2.68, 6.49) and 0.60 (95% confidence interval: 0.44, 0.83) for diabetes.

Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition, 28(6).More infoSarcopenia is defined as an age-related decrease in muscle mass and performance. Several consensus definitions of sarcopenia exist, each providing different cut points and methodologies for assessing muscle mass and muscle strength. Thus, wide variation in the prevalence of sarcopenia has been reported, generally ranging up to 45% for men and 26% for women. Risk factors for sarcopenia include age, malnutrition, and physical inactivity. Additional evidence suggests a protective role for protein supplementation in older adults to preserve lean body mass and prevent frailty, accepted intervention targets for reducing the risk of sarcopenia. Protein supplements vary widely in their composition, and small trials of heterogeneous study designs have made it difficult to extrapolate findings to develop data-driven, evidence-based recommendations for protein supplementation in sarcopenia prevention. Short-term randomized controlled trials of muscle protein synthesis have demonstrated that whey protein increases synthesis more so than casein or soy isolates. Studies also suggest that essential amino acids stimulate muscle protein synthesis to a greater extent than nonessential amino acids. This review summarizes the epidemiological and clinical trial evidence establishing the current definitions for sarcopenia and provides an overview of the state of the evidence for protein supplementation to prevent and/or mitigate sarcopenia.

Daily consumption of grapefruit for 6 weeks reduces urine F2-isoprostanes in overweight adults with high baseline values but has no effect on plasma high-sensitivity C-reactive protein or soluble vascular cellular adhesion molecule 1. The Journal of Nutrition, 143(10).More infoIndividuals with obesity and metabolic syndrome (MetS) are at increased risk of cardiovascular disease, in part due to heightened inflammatory/oxidative processes. Results from epidemiologic and experimental studies suggest that citrus, and grapefruit in particular, may have a role in promoting vascular health, although clinical trial data are lacking. Here, we evaluated the anti-inflammatory/antioxidant effects of habitual grapefruit consumption in 69 overweight/obese men and women and in a subsample of participants with MetS (n = 29). Participants were randomly assigned to either a grapefruit group in which they consumed a low bioactive diet plus 1.5 grapefruit/d for 6 wk (n = 37, n = 14 with MetS) or to a control condition in which a low bioactive diet devoid of citrus was consumed (n = 32, n = 15 with MetS). Plasma soluble vascular adhesion molecule-1 (sVCAM-1), plasma high-sensitivity C-reactive protein (hsCRP), and urinary F2-isoprostanes were evaluated before and after the intervention phase. F2-isoprostane concentrations were not different in the grapefruit versus control arm after the intervention (12.4 ± 6.4 vs. 15.9 ± 9.0 ng/mg creatinine, P = 0.16), whereas plasma hsCRP concentrations tended to be lower in the grapefruit versus control arm postintervention (2.1 ± 1.5 vs. 2.8 ± 2.0 mg/L, P = 0.09). In adults with MetS, grapefruit consumption tended to result in lower postintervention F2-isoprostane concentrations compared with the control condition (12.0 ± 4.5 vs. 18.3 ± 10.9 ng/mg creatinine, P = 0.06). Furthermore, those with high baseline F2-isoprostane concentrations experienced significant reductions in this biomarker in response to grapefruit consumption (P = 0.021). Change in sVCAM-1 concentrations did not vary by treatment arm nor were there differences between arms postintervention. These results suggest that intake of grapefruit twice daily for 6 wk does not significantly reduce inflammation and oxidative stress, although there is a suggestion of favorable modulation of oxidative stress in overweight and obese adults with MetS or those with high baseline urine F2-isoprostane concentrations.

Cancer Prevention Research, 6. doi:10.1158/1940-6215.prev-13-a48More infoThe association between physical activity and colorectal adenoma is equivocal. This study was designed to assess the relationship between various physical activity types and colorectal adenoma recurrence in a pooled sample of participants from the Wheat Bran Fiber and Ursodeoxycholic Acid phase III clinical trials with available data from the baseline Arizona Activity Frequency Questionnaire and a follow-up colonoscopy (n=1,730). Logistic regression modeling was used to estimate the relationship between sedentary, recreational, and household activity on colorectal adenoma recurrence overall and stratified by gender. No statistically significant associations were found between any activity type and colorectal adenoma recurrence overall however, males with the highest sedentary time demonstrated a statistically significant 45% higher odds of adenoma recurrence. Compared to the lowest quartile of sedentary time, the ORs (95% CIs) for the second, third, and fourth quartiles among men were 1.31 (0.93, 1.84), 1.47 (1.04, 2.09) and 1.45 (1.02, 2.06) respectively (P trend=0.03). In males, those with low recreational activity and high sedentary time was also associated with greater risk for recurrent adenoma, with an OR (95% CI) of 1.41(1.00-2.00) for high sedentary time/low recreational activity compared to the reference group (low sedentary time/low recreational activity). Our results suggests that sedentary time is associated with a higher risk of colorectal adenoma recurrence among men, supporting a role for sedentary lifestyle in the early stages of carcinogenesis. Efforts to intervene on sedentary time should be evaluated as a method for reducing recurrent adenomas. Citation Format: Christine L. Sardo, Erin L. Ashbeck, Elizabeth A. Hibler, Denise Roe, Robin B.

Correlates of 25-hydroxyvitamin D and breast cancer stage in the Women's Healthy Eating and Living Study. Nutrition and Cancer, 65(2).More infoInverse associations between circulating 25-hydroxyvitamin D [25(OH)D] and breast cancer stage have been reported, thus it is critical to understand the variables that contribute to 25(OH)D levels among women with breast cancer. Among 904 women in the Women's Healthy Eating and Living Study, plasma 25(OH)D concentrations were measured and data on demographic characteristics, diet, physical activity, and tumor characteristics were collected at study entry. Statistically significant associations with 25(OH)D concentrations were observed for body mass index (BMI), body surface area (BSA), height, smoking, total vitamin D intake, physical activity, and race or ethnicity. Of the correlates of 25(OH)D, BMI, BSA, height, physical activity, and study site were associated with stage of breast cancer; however, concentrations of 25(OH)D were not significantly related to stage. In fully adjusted logistic regression models, the ORs (95% CIs) for the association between vitamin D deficiency and Stage II and III cancers were 0.85 (0.59-1.22) and 1.23 (0.71-2.15), respectively (P trend = 0.59), compared to Stage I. This study confirms previous work regarding the correlates of 25(OH)D concentrations but does not provide support for an association between vitamin D status and breast cancer stage.

Cancer causes & control : CCC, 24(6).More infoStudies of the relationship between anthropometric indices of obesity and colorectal cancer risk in women have shown only weak and inconsistent associations. Given the limitations of such indices, we used dual-energy X-ray absorptiometry (DXA)-derived measures of body fat obtained in the Women's Health Initiative to examine the association between body fat and risk of incident colorectal cancer. We compared these risk estimates with those obtained using conventional anthropometric measurements (body mass index and waist circumference). After exclusions, the study population consisted of 11,124 postmenopausal women with DXA measurements at baseline and no history of colorectal cancer. After a median follow-up period of 12.9 years, 169 incident colorectal cancer cases were ascertained. Cox's proportional hazards models were used to estimate hazard ratios and 95 % confidence intervals for the exposures of interest. Neither DXA-derived body fat measures nor anthropometric measures showed significant associations with risk. In view of the limited number of cases, we cannot rule out the existence of weak associations of these measures with risk of colorectal cancer.

Regression calibration in nutritional epidemiology: example of fat density and total energy in relationship to postmenopausal breast cancer. American Journal of Epidemiology, 178(11).More infoRegression calibration using biomarkers provides an attractive approach to strengthening nutritional epidemiology. We consider this approach to assessing the relationship of fat and total energy consumption with postmenopausal breast cancer. In analyses that included fat density data, biomarker-calibrated total energy was positively associated with postmenopausal breast cancer incidence in cohorts of the US Women's Health Initiative from 1994-2010. The estimated hazard ratio for a 20% increment in calibrated food frequency questionnaire (FFQ) energy was 1.22 (95% confidence interval (CI): 1.15, 1.30). This association was not evident without biomarker calibration, and it ceased to be apparent following control for body mass index (weight (kg)/height (m)(2)), suggesting that the association is mediated by body fat deposition over time. The hazard ratio for a corresponding 40% increment in FFQ fat density was 1.05 (95% CI: 1.00, 1.09). A stronger fat density association, with a hazard ratio of 1.19 (95% CI: 1.00, 1.41), emerged from analyses that used 4-day food records for dietary assessment. FFQ-based analyses were also carried out by using a second dietary assessment in place of the biomarker for calibration. This type of calibration did not correct for systematic bias in energy assessment, but may be able to accommodate the "noise" component of dietary measurement error. Implications for epidemiologic applications more generally are described.

Body fat and breast cancer risk in postmenopausal women: a longitudinal study. Journal of Cancer Epidemiology, 2013.More infoAssociations between anthropometric indices of obesity and breast cancer risk may fail to capture the true relationship between excess body fat and risk. We used dual-energy-X-ray-absorptiometry- (DXA-) derived measures of body fat obtained in the Women's Health Initiative to examine the association between body fat and breast cancer risk; we compared these risk estimates with those for conventional anthropometric measurements. The study included 10,960 postmenopausal women aged 50-79 years at recruitment, with baseline DXA measurements and no history of breast cancer. During followup (median: 12.9 years), 503 incident breast cancer cases were diagnosed. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using Cox proportional hazards models. All baseline DXA-derived body fat measures showed strong positive associations with breast cancer risk. The multivariable-adjusted HR for the uppermost quintile level (versus lowest) ranged from 1.53 (95% CI 1.14-2.07) for fat mass of the right leg to 2.05 (1.50-2.79) for fat mass of the trunk. Anthropometric indices (categorized by quintiles) of obesity (BMI (1.97, 1.45-2.68), waist circumference (1.97, 1.46-2.65), and waist : hip ratio (1.91, 1.41-2.58)) were all strongly, positively associated with risk and did not differ from DXA-derived measures in prediction of risk.

Investigating the Association of Lactation History and Postmenopausal Breast Cancer Risk in the Women's Health Initiative. Nutrition and Cancer, 65(7).More infoProlonged lactation (≥24 mo) has been associated with reduced breast cancer risk. This research examined this association in postmenopausal women in the Women's Health Initiative (WHI) Hormone Trial (HT) and Observational Study (OS). This retrospective cohort analysis included 69,358 predominantly overweight (65.4%), white (83.2%) postmenopausal women without breast cancer. Women in the HT were randomized to 0.625 mg conjugated equine estrogen (CEE), 0.625 CEE + 2.5 mg medroxyprogesterone acetate (CEE/MPA), or placebo. OS participants had no restrictions on hormone use. Lactation history was assessed via WHI Reproductive History Questionnaire. Most women breastfed at least 1 mo (58.0%); 35.4% breastfed 1-2 children; and 6.5% stated having breastfed ≥24mo. Women in the HT-CEE who breastfed their first child between 20-24 yr of age demonstrated a nonsignificant decreased risk of breast cancer (HR: 0.62; 95% CI: 0.38, 1.01). OS participants who reported CEE/MPA hormone use and age of first breastfeeding ≥30 yr showed a significant increased risk of breast cancer (HR: 1.66; 95% CI: 1.14, 2.41). Risk was increased if age of last breastfeeding was ≥35yr (HR: 1.50; 95% CI: 1.05, 2.14). This research did not demonstrate a significantly decreased risk of postmenopausal breast cancer in women who breastfed for ≥24 mo during their lifetime.

Short sleep duration is associated with decreased serum leptin, increased energy intake, and decreased diet quality in postmenopausal women. Obesity (Silver Spring, Md.).More infoObjective: Short sleep duration induces hormonal perturbations contributing to hyperphagia, insulin resistance, and obesity. The majority of these studies are conducted in young adults. This analysis in a large (n= 769) sample of postmenopausal women (median age 63y) sought to 1) confirm that sleep duration and sleep quality are negatively correlated with circulating leptin concentrations and 2) to examine the relationship between self-reported sleep, dietary energy intake, and diet quality, as well as, investigate the role of leptin in these associations. Design and Methods: Sleep duration/ quality, insomnia, and dietary intake were determined via self-report. Blood samples were collected following an overnight fast to assess serum leptin concentration. All analyses were adjusted for total body fat mass. Results: Women reporting ≤6h sleep/night had lower serum leptin concentrations than those reporting ≥8h sleep (P= 0.04). Furthermore, those with ≤6h sleep/night reported higher dietary energy intake (p=0.01) and lower diet quality (P= 0.04) than the reference group (7h sleep/night). Women sleeping ≥8h also reported lower diet quality than the reference group (P= 0.02). Importantly, serum leptin did not confound these associations. Conclusions: These results provide evidence that sleep duration is inversely associated with serum leptin and dietary energy intake in postmenopausal women.

Currently, cardiovascular disease (CVD) is the leading cause of death in women, followed by cancer and stroke. Breast cancer, while associated with lower mortality than most other cancers, is the leading cause of cancer-related morbidity in women. Osteoporosis also threatens women, particularly after menopause. Importantly, each of these diagnoses in aging women share a commonality in that lifestyle choices, including diet, play a primary role in prevention and treatment of these diseases. This practice paper provides a synopsis of current dietary recommendations for CVD, osteoporosis, and breast cancer in women. Registered dietitian nutritionists (RDNs) and dietetic technicians, registered play important roles in risk reduction for these diagnoses, and RDNs are uniquely qualified to provide medical nutrition therapy. For CVD, osteoporosis, or breast cancer, current recommendations for nutritional care suggest women should achieve and maintain a healthy body weight with avoidance of visceral adiposity. Nutrient density, with an emphasis on consumption of a variety of foods to acquire important micronutrients and bioactive components, is also central to effective medical nutrition therapy. Furthermore, RDNs should have a working knowledge of the therapeutic role of dietary supplementation, particularly for osteoporosis prevention.

Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology.More infoOvarian cancer is a leading cause of gynecological cancer death. There is a need to identify modifiable dietary risk factors for this disease. To evaluate the role of diet in ovarian cancer risk we performed a PRISMA-directed systematic review that included prospective cohort studies with > 200 cases (n=24). Higher risk for ovarian cancer was shown for total, animal, and dairy fat (5 of 9 studies), as well as total nitrate and possibly total vitamin C. No associations were demonstrated for red meat, fiber, vitamin A, vitamin E, β-carotene, or folate. Vegetables were associated with lower risk in one of three studies; fruit showed no association although risk estimates were all greater than 1.0. Isoflavones and flavonoids were associated with modestly lower risk in two studies and tea intake was associated with lower risk in one of two studies. This review suggests that no specific dietary factors are consistently associated with ovarian cancer risk. Data by tumor subtypes are limited, but suggest that differential associations by tumor subtype may exist and should be evaluated. Studies of ample sample size, varied exposure, which can better control for dietary measurement error, are needed to fully define dietary recommendations for ovarian cancer prevention.

American journal of epidemiology, 177(6), 576-85. doi:10.1093/aje/kws269More infoWe used a biomarker of activity-related energy expenditure (AREE) to assess measurement properties of self-reported physical activity and to determine the usefulness of AREE regression calibration equations in the Women's Health Initiative. Biomarker AREE, calculated as the total energy expenditure from doubly labeled water minus the resting energy expenditure from indirect calorimetry, was assessed in 450 Women's Health Initiative participants (2007-2009). Self-reported AREE was obtained from the Arizona Activity Frequency Questionnaire (AAFQ), the 7-Day Physical Activity Recall (PAR), and the Women's Health Initiative Personal Habits Questionnaire (PHQ). Eighty-eight participants repeated the protocol 6 months later. Reporting error, measured as log(self-report AREE) minus log(biomarker AREE), was regressed on participant characteristics for each instrument. Body mass index was associated with underreporting on the AAFQ and PHQ but overreporting on PAR. Blacks and Hispanics underreported physical activity levels on the AAFQ and PAR, respectively. Underreporting decreased with age for the PAR and PHQ. Regressing logbiomarker AREE on logself-reported AREE revealed that self-report alone explained minimal biomarker variance (R(2) = 7.6, 4.8, and 3.4 for AAFQ, PAR, and PHQ, respectively). R(2) increased to 25.2, 21.5, and 21.8, respectively, when participant characteristics were included. Six-month repeatability data adjusted for temporal biomarker variation, improving R(2) to 79.4, 67.8, and 68.7 for AAFQ, PAR, and PHQ, respectively. Calibration equations "recover" substantial variation in average AREE and valuably enhance AREE self-assessment.

Breast cancer research and treatment, 141(3), 495-505. doi:10.1007/s10549-013-2712-xMore infoMultivitamin use is common in the United States. It is not known whether multivitamins with minerals supplements (MVM) used by women already diagnosed with invasive breast cancer would affect their breast cancer mortality risk. To determine prospectively the effects of MVM use on breast cancer mortality in postmenopausal women diagnosed with invasive breast cancer, a prospective cohort study was conducted of 7,728 women aged 50-79 at enrollment in the women's health initiative (WHI) in 40 clinical sites across the United States diagnosed with incident invasive breast cancer during WHI and followed for a mean of 7.1 years after breast cancer diagnosis. Use of MVM supplements was assessed at WHI baseline visit and at visit closest to breast cancer diagnosis, obtained from vitamin pill bottles brought to clinic visit. Outcome was breast cancer mortality. Hazard ratios and 95 % confidence intervals (CIs) for breast cancer mortality comparing MVM users to non-users were estimated using Cox proportional hazard regression models. Analyses using propensity to take MVM were done to adjust for potential differences in characteristics of MVM users versus non-users. At baseline, 37.8 % of women reported MVM use. After mean post-diagnosis follow-up of 7.1 ± 4.1 (SD) years, there were 518 (6.7 %) deaths from breast cancer. In adjusted analyses, breast cancer mortality was 30 % lower in MVM users as compared to non-users (HR = 0.70; 95 % CI 0.55, 0.91). This association was highly robust and persisted after multiple adjustments for potential confounding variables and in propensity score matched analysis (HR = 0.76; 95 % CI 0.60-0.96). Postmenopausal women with invasive breast cancer using MVM had lower breast cancer mortality than non-users. The results suggest a possible role for daily MVM use in attenuating breast cancer mortality in women with invasive breast cancer but the findings require confirmation.

Participants completed questionnaires on diet and medical history, and serum samples were collected from all women to measure circulating 25(OH)D concentrations..The participants had a mean age of 47.8 y and a mean body mass index (BMI; in kg/m(2)) of 30.0. Breast cancer cases had significantly lower (mean ± SD) serum concentrations of 25(OH)D (9.4 ± 6.4 ng/mL) than did controls (15.4 ± 12.3 ng/mL; P = 0.001). In comparison with those in the highest category of vitamin D status for this population (≥20 ng/mL), the adjusted ORs (95% CIs) for invasive breast cancer were 6.1 (2.4, 15.1) for women with a serum 25(OH)D concentration

Genome-wide association analysis of red blood cell traits in African Americans: the COGENT Network.. Human molecular genetics, 22(12), 2529-38. doi:10.1093/hmg/ddt087More infoLaboratory red blood cell (RBC) measurements are clinically important, heritable and differ among ethnic groups. To identify genetic variants that contribute to RBC phenotypes in African Americans (AAs), we conducted a genome-wide association study in up to ~16 500 AAs. The alpha-globin locus on chromosome 16pter [lead SNP rs13335629 in ITFG3 gene; P < 1E-13 for hemoglobin (Hgb), RBC count, mean corpuscular volume (MCV), MCH and MCHC] and the G6PD locus on Xq28 [lead SNP rs1050828; P < 1E - 13 for Hgb, hematocrit (Hct), MCV, RBC count and red cell distribution width (RDW)] were each associated with multiple RBC traits. At the alpha-globin region, both the common African 3.7 kb deletion and common single nucleotide polymorphisms (SNPs) appear to contribute independently to RBC phenotypes among AAs. In the 2p21 region, we identified a novel variant of PRKCE distinctly associated with Hct in AAs. In a genome-wide admixture mapping scan, local European ancestry at the 6p22 region containing HFE and LRRC16A was associated with higher Hgb. LRRC16A has been previously associated with the platelet count and mean platelet volume in AAs, but not with Hgb. Finally, we extended to AAs the findings of association of erythrocyte traits with several loci previously reported in Europeans and/or Asians, including CD164 and HBS1L-MYB. In summary, this large-scale genome-wide analysis in AAs has extended the importance of several RBC-associated genetic loci to AAs and identified allelic heterogeneity and pleiotropy at several previously known genetic loci associated with blood cell traits in AAs.

Effects of a carrot juice intervention on plasma carotenoids, oxidative stress, and inflammation in overweight breast cancer survivors. Nutrition and cancer, 64(2).More infoEvidence suggests that higher plasma carotenoid concentrations are protective in relation to breast cancer recurrence. This simple randomized carrot juice intervention study was designed to test the hypothesis that daily intake of 8 ounces of fresh BetaSweet (anthocyanin-rich) or Balero orange carrot juice would increase plasma total carotenoid concentrations to levels previously shown to be associated with reduced breast cancer recurrence. It was hypothesized that regular carrot juice intake would be associated with reductions in oxidative stress (8-iso-PGF2α) and inflammation (thromboxane B2, prostaglandin E2 metabolites, and hsC-reactive protein). Sixty-nine overweight breast cancer survivors consumed fresh carrot juice made from study-provided carrots for 3 wk. Total plasma carotenoids increased by 1.65 and 1.38 umol/L for the BetaSweet and Balero carrot juice, respectively. Rise in total plasma carotenoids for the overall sample was inversely associated with 8-iso-PGFα (OR: 0.13; 95% CI: 0.20 to 0.75; no differences were shown by carrot variety. These results suggest daily intake of fresh carrot juice is a simple and effective approach to increasing plasma total carotenoids and in turn reducing oxidative stress, but not inflammatory markers, in women previously treated for breast cancer.

The effects of daily consumption of grapefruit on body weight, lipids, and blood pressure in healthy, overweight adults. Metabolism: clinical and experimental, 61(7).More infoFolklore has suggested that consuming grapefruit may promote weight control. Sparse data exist to support this hypothesis, although there is some evidence of health promotion effects with regard to blood pressure control and modulation of circulating lipids. The aim of this randomized controlled trial was to prospectively evaluate the role of grapefruit in reducing body weight and blood pressure and in promoting improvements in the lipid profile in overweight adults (N = 74). Following a 3-week washout diet low in bioactive-rich fruits and vegetables, participants were randomized to either the control diet (n = 32) or daily grapefruit (n = 42) in the amount of one half of a fresh Rio-Red grapefruit with each meal (3× daily) for 6 weeks. No differences between group in weight, blood pressure, or lipids were demonstrated. Grapefruit consumption was associated with modest weight loss (-0.61 ± 2.23 kg, P = .097), a significant reduction in waist circumference (-2.45 ± 0.60 cm, P = .0002), and a significant reduction in systolic blood pressure (-3.21 ± 10.13 mm Hg, P = .03) compared with baseline values. Improvements were observed in circulating lipids of those consuming grapefruit, with total cholesterol and low-density lipoprotein significantly decreasing by -11.7 mg/dL (P = .002) and -18.7 mg/dL (P < .001), respectively, compared with baseline values. This study suggests that consumption of grapefruit daily for 6 weeks does not significantly decrease body weight, lipids, or blood pressure as compared with the control condition. However, the improvements in blood pressure and lipids demonstrated in the intervention group suggest that grapefruit should be further evaluated in the context of obesity and cardiovascular disease prevention.

Hortscience, 47(12), 1698-1704. doi:10.21273/hortsci.47.12.1698More info‘Durinta’ tomatoes were grown hydroponically using rockwool substrate in greenhouses to assess the seasonal and postharvest changes of selected quality attributes including lycopene and total soluble solids (TSS, % Brix) concentrations in fruit when grown under varied electrical conductivity (EC) in the nutrient solution. Two levels of EC examined in this study were 2.4 and 4.8 dS·m−1 for standard low EC and high EC treatments, respectively. All fruits at light-red and red ripeness stages were harvested and weighed every week, and nine fruits visually representing the median group of red fruits were selected from each EC treatment and subject to measurements of lycopene and TSS concentrations. Of 53 harvest weeks (Dec. 2005 to Dec. 2006), 45 weeks were subject to fruit quality analyses at harvest and 3 weeks were subject to postharvest quality analyses. Lycopene concentration and TSS showed seasonal differences with larger variation in lycopene, but the high EC treatment induced an overall average of 18% greater lycopene concentration and a 20% greater TSS. The regression analyses indicated that efflux solution EC (EEC) was the most influential factor for both lycopene and TSS concentrations, but secondary influential factors were greenhouse temperature for lycopene and daily light integral for TSS. Postharvest storage test showed that selected fruit quality attributes (lycopene, TSS, ascorbic acid, and total phenolics) changed minimally or not at all for 10 days when stored at 12 °C, a widely recommended tomato postharvest storage temperature. Overall, we consider that producing lycopene-rich tomato by controlling EC of nutrient solution was feasible during year-round greenhouse production using a high-wire rockwool culture system.

Vitamin C and zinc intakes are related to bone macroarchitectural structure and strength in prepubescent girls. Calcified tissue international, 91(6).More infoThe extent to which nutrient intake may influence bone structure and strength during maximal rates of skeletal growth remains uncertain. We examined the relationship of dietary intake of micronutrients and bone macroarchitectural structure in young girls. This cross-sectional analysis included baseline data from 363 fourth- and sixth-grade girls enrolled in the Jump-In study. Nutrient intake was assessed using the Harvard Youth/Adolescent Food Frequency Questionnaire. Volumetric BMD (vBMD), bone geometry, and strength were measured by peripheral quantitative computed tomography. Correlations and regression modeling assessed relations between usual nutrient intake and bone parameters. In fourth-grade girls, metaphyseal and diaphyseal area and circumferences as well as diaphyseal strength were associated with vitamin C intake (r = 0.15-0.19, p < 0.05). Zinc intake was correlated with diaphyseal vBMD (r = 0.15-0.16, p < 0.05). Using multiple linear regression to adjust for important covariates, we observed significant independent associations for vitamin C and zinc with bone parameters. For every milligram per day of vitamin C intake trabecular area increased by 11 %, cortical strength improved by 14 %, and periosteal and endosteal circumferences increased by 5 and 8.6 %, respectively. For every milligram per day of zinc intake, cortical vBMD increased by

Weight loss is associated with increased serum 25-hydroxyvitamin D in overweight or obese women. Obesity (Silver Spring, Md.), 20(11).More infoLow circulating concentrations of vitamin D metabolites have been associated with increased risk for several diseases and clinical conditions. Large observational studies and surveys have shown that obesity is independently associated with lower serum 25-hydroxyvitamin D (25(OH)D) concentration. Few studies have examined the effect of weight loss on serum 25(OH)D concentration. The purpose of this study was to prospectively examine the effect of weight loss on serum 25(OH)D concentration. Data were collected from 383 overweight or obese women who participated in a 2-year clinical trial of a weight-loss program, in which 51% (N = 195) lost at least 5% of baseline weight by 24 months, 18% (N = 67) lost 5-10%, and 33% (N = 128) lost >10%. Women who did not lose weight at 24 months had an increase in serum 25(OH)D of 1.9 (9.7) ng/ml (mean (SD)); 25(OH)D increased by 2.7 (9.1) ng/ml for those who lost 5-10% of baseline weight; and 25(OH)D increased by 5.0 (9.2) ng/ml for those who lost >10% of baseline weight (P = 0.014). At baseline, 51% (N = 197) of participants met or exceeded the recommended serum concentration of 20 ng/ml. By study end, 64% (N = 230) of overweight or obese women met this goal, as well as 83% (N = 20) of those whose weight loss achieved a normal BMI. These findings suggest that weight loss, presumably associated with a reduction in body fat, is associated with increased serum 25(OH)D concentration in overweight or obese women.

Relationship between sleep quality and quantity and weight loss in women participating in a weight-loss intervention trial. Obesity (Silver Spring, Md.), 20(7).More infoEvidence suggests that individuals who report fewer total hours of sleep are more likely to be overweight or obese. Few studies have prospectively evaluated weight-loss success in relation to reported sleep quality and quantity. This analysis sought to determine the association between sleep characteristics and weight loss in overweight or obese women enrolled in a randomized clinical trial of a weight-loss program. We hypothesized that in overweight/obese women, significant weight loss would be demonstrated more frequently in women who report a better Pittsburgh Sleep Quality Index (PSQI) Global Score or sleep >7 h/night as compared to women who report a worse PSQI score or sleep ≤7 h/night. Women of ages 45.5 ± 10.4 (mean ± SD) years and BMI of 33.9 ± 3.3 (n = 245) were randomized and completed PSQI at baseline and 6 months; 198 had weight change assessed through 24 months. At baseline, 52.7% reported PSQI scores above the clinical cutoff of 5. Better subjective sleep quality increased the likelihood of weight-loss success by 33% (relative risk (RR), 0.67; 95% confidence interval (CI), 0.52-0.86), as did sleeping >7 h/night. A worse Global Score at 6 months was associated with a 28% lower likelihood of continued successful weight loss at 18 months, but unassociated by 24 months. These results suggest that sleep quality and quantity may contribute to weight loss in intervention-based studies designed to promote weight control in overweight/obese adult women.

Food and Nutrition Sciences, 2012(12), 1636-1643. doi:10.4236/fns.2012.312214More infoPrevious evidence indicates that a child’s body mass index (BMI) and eating behaviors are often related to the BMI and eating behaviors of his/her parents. Additionally, there is evidence suggesting that fruit and vegetable intake may impart weight control benefits. The purpose of this study was to examine the relationship between mother’s BMI and the intake/availability of fruits and vegetables in the home, as well as mother’s perceived body shape of her child. This is a cross sectional, descriptive analysis of results from a large internet-based survey of Generation X and Y mothers evaluating the role of fruit and vegetable consumption and health behaviors in US families. Mothers (n = 1469) with children under the age of 18 living in the home reported her BMI, her fruit and vegetable intake, and fruit and vegetable availability in the home. Additionally, mothers with children between the ages of 2 and 12 (n = 1177) reported her child’s body shape (using graduated images of children ranging from the 3rd - 97th percentiles of BMI). Mother’s BMI was not related to fruit or vegetable intake, though it was inversely related to fruit, but not vegetable, availability in the home. Mother’s BMI was also positively related to child’s body shape, and mother’s fruit, but not vegetable, intake was inversely related to child’s body shape. Our findings support a potential role for fruit availability promoting healthy BMI in mothers and/or healthier body shape in their children.

Compared with women with serum concentrations of 25(OH)D ≥ 30 ng/mL, adjusted odds ratios (95% CI) for breast cancer recurrence were 1.14 (0.57, 2.31) for those with concentrations < 10 ng/mL, 1.00 (0.68-1.48) for concentrations ≥ 10 and < 20 ng/mL, and 1.05 (0.76, 1.47) for concentrations ≥ 20 and < 30 ng/mL. No significant associations were observed when analyses were stratified by pre- and postmenopausal status or for local, regional, or distant recurrence or death. Vitamin D intake was not related to breast cancer recurrence overall, although for premenopausal women there was a significant inverse association between dietary vitamin D intake and recurrence (P for trend = 0.02)..These results do not provide support for a relation between concentrations of 25(OH)D after treatment and the recurrence of breast cancer.

The Journal of nutrition, 141(10), 1827-33. doi:10.3945/jn.111.139659More infoThe optimal amount of vegetable consumption required to reduce chronic disease risk is widely debated. Intervention trials evaluating biological activity of vegetables at various doses are limited. We conducted a 3-dose, crossover feeding trial to test the hypothesis that vegetable intake is associated in a dose-dependent manner with increased plasma carotenoids and subsequently reduced oxidative stress and inflammation in 49 overweight, postmenopausal women. Participants were assigned in random order to 2 (130 g), 5 (287 g), and 10 (614 g) daily servings of fresh, greenhouse-grown vegetables for 3-wk intervals with a 4-wk washout period between treatments. Plasma total carotenoids significantly increased from 1.63 to 2.07 μmol/L with a dose of 2 vegetable servings, from 1.49 to 2.84 μmol/L with a dose of 5 vegetable servings, and from 1.40 to 4.42 μmol/L with a dose of 10 vegetable servings (pre-post paired ttests, all P < 0.001). The change during each feeding period increased with each dose level (P < 0.001). Urine concentrations of 8-isoprostane F2α, hexanoyl lysine, and serum high sensitivity C-reactive protein were not affected by any administered vegetable dose. In this variable-dose vegetable study, a dose-response for plasma carotenoids was demonstrated without significant change in oxidative stress and inflammation in overweight, postmenopausal women.

Oncology Reviews, 5(1), 31-42. doi:10.1007/s12156-010-0066-8More infoAlthough limited, observations from cell culture, animal, and epidemiological studies support the presence of anti-cancer properties in citrus peel and the primary bioactive food constituent, d-limonene. Early evidence from animal models suggests that when ingested, d-limonene exhibits a wide spectrum of biologic activity including chemotherapeutic and chemopreventive effects. In some of these early models, an analog of d-limonene, perillyl alcohol, demonstrated a more potent effect than d-limonene itself. Yet, when perillyl alcohol advanced to clinical trials, several trials were ended early due to dose-limiting toxicities. Alternatively, oral d-limonene administration in humans is well tolerated even at high doses supporting its investigation as a potential bioactive for cancer prevention. Though the exact mechanisms of action of d-limonene are unclear, immune modulation and anti-proliferative effects are commonly reported. Here, we review the pre-clinical evidence for d-limonene’s anti-cancer mechanisms, bioavailability, and safety, as well as the evidence for anti-cancer effects in humans, focusing on studies relevant to its use in the prevention and treatment of breast cancer.

Nutrition and cancer, 63(3), 327-33. doi:10.1080/01635581.2011.535957More infoPrevious studies examining the relationship between micronutrient intakes and survival following diagnosis of breast cancer have reported mixed results. This may be partly due to considerable variance in amounts of micronutrients consumed from diet and supplements across studies. Early-stage breast cancer survivors (N = 3081) completed four 24-h dietary and supplement recalls at the baseline assessment (1995 to 2000) and were followed for a median of 9.0 yr. Mean micronutrient intakes were compared to dietary reference intakes (DRI) to assess micronutrient adequacy for both users and nonusers of supplements. Cox regressions were performed to assess whether intakes of selected micronutrients were associated with all-cause mortality. Four hundred and twelve deaths occurred between baseline and August 2009. Among these women, more supplement users had adequate micronutrient intakes than nonusers for 15 out of 17 micronutrients. Less than 10% of supplement users (

We examined, using data from the Women's Healthy Eating and Living (WHEL) study, the effect of soy intake on breast cancer prognosis..Three thousand eighty-eight breast cancer survivors, diagnosed between 1991 and 2000 with early-stage breast cancer and participating in WHEL, were followed for a median of 7.3 years. Isoflavone intakes were measured postdiagnosis by using a food frequency questionnaire. Women self-reported new outcome events semiannually, which were then verified by medical records and/or death certificates. HRs and 95% CIs representing the association between either a second breast cancer event or death and soy intake were computed, adjusting for study group and other covariates, using the delayed entry Cox proportional hazards model..As isoflavone intake increased, risk of death decreased (P for trend = 0.02). Women at the highest levels of isoflavone intake (>16.3 mg isoflavones) had a nonsignificant 54% reduction in risk of death..Our study is the third epidemiologic study to report no adverse effects of soy foods on breast cancer prognosis..These studies, taken together, which vary in ethnic composition (two from the United States and one from China) and by level and type of soy consumption, provide the necessary epidemiologic evidence that clinicians no longer need to advise against soy consumption for women with a diagnosis of breast cancer.

Marine fatty acid intake is associated with breast cancer prognosis.. The Journal of nutrition, 141(2), 201-6. doi:10.3945/jn.110.128777More infoEPA and DHA, long-chain (n-3) PUFA largely obtained from fish, inhibit the proliferation of breast cancer cells in vitro and reduce the initiation and progression of breast tumors in laboratory animals. Our purpose in this analysis was to examine whether intake of these marine fatty acids (EPA and DHA) were associated with prognosis in a cohort of women who had been diagnosed and treated for early stage breast cancer (n = 3,081). Median follow-up was 7.3 y. Dietary intake was assessed using 24-h recalls (~4 recalls per dietary assessment obtained at 7 time points over 6 y). Survival models with time-dependent covariates were used to examine the association of repeated measures of dietary intake of EPA and DHA from food (i.e., marine sources) and supplements with disease-free survival and overall survival. Women with higher intakes of EPA and DHA from food had an approximate 25% reduced risk of additional breast cancer events [tertile 2: HR = 0.74 (95% CI = 0.58-0.94); tertile 3: HR = 0.72 (95% CI = 0.57-0.90)] compared with the lowest tertile of intake. Women with higher intakes of EPA and DHA from food had a dose-dependent reduced risk of all-cause mortality [tertile 2: HR = 0.75 (95% CI = 0.55-1.04); tertile 3: HR = 0.59 (95% CI = 0.43-0.82)]. EPA and DHA intake from fish oil supplements was not associated with breast cancer outcomes. The investigation indicates that marine fatty acids from food are associated with reduced risk of additional breast cancer events and all-cause mortality.

Breast cancer research and treatment, 127(2), 541-7. doi:10.1007/s10549-010-1236-xMore infoPhysical health-related quality of life scores have been, inconsistently, associated with breast cancer prognosis. This analysis examined whether change in physical health scores were related to outcomes in women with a history of breast cancer. 2343 breast cancer survivors in a randomized diet trial provided self-reported assessment of physical health-related quality of life at baseline and year 1. Based on change in physical health score, participants were grouped into subpopulations of decreased physical health, no/minimal changes, and increased physical health. Cox regression analysis assessed whether change in physical health (from baseline to year 1) predicted disease-free and overall survival; hazard ratio (HR) was the measure of association. There were 294 additional breast cancer events and 162 deaths among women followed for 7.3 years. Improvements in physical health were associated with younger age, lower BMI, being employed, not receiving tamoxifen, lower physical activity, and lower baseline physical and mental health. There was no association of change in physical health with additional breast cancer events or mortality among women diagnosed ≤ 2 years before study enrollment. However, among women who entered the study >2 years post-diagnosis, the HR for increased compared to decreased physical health was 0.38 (95% CI, 0.16-0.85) for all-cause mortality. These results appear to support testing an intervention to improve physical health in breast cancer patients among patients after the acute stage of treatment.

Psycho-oncology, 20(3), 252-9. doi:10.1002/pon.1742More infoHealth-related quality of life has been hypothesized to predict time to additional breast cancer events and all-cause mortality in breast cancer survivors..Women with early-stage breast cancer (n=2967) completed the SF-36 (mental and physical health-related quality of life) and standardized psychosocial questionnaires to assess social support, optimism, hostility, and depression prior to randomization into a dietary trial. Cox regression was performed to assess whether these measures of quality of life and psychosocial functioning predicted time to additional breast cancer events and all-cause mortality; hazard ratios were the measure of association..There were 492 additional breast cancer events and 301 deaths occurred over a median 7.3 years (range: 0.01-10.8 years) of follow-up. In multivariate models, poorer physical health was associated with both decreased time to additional breast cancer events and all-cause mortality (p trend=0.005 and 0.004, respectively), while greater hostility predicted additional breast cancer events only (p trend=0.03). None of the other psychosocial variables predicted either outcome. The hazard ratios comparing persons with poor (bottom two quintiles) to better (top three quintiles) physical health were 1.42 (95% CI: 1.16, 1.75) for decreased time to additional breast cancer events and 1.37 (95% CI: 1.08, 1.74) for all-cause mortality. Potentially modifiable factors associated with poor physical health included higher body mass index, lower physical activity, lower alcohol consumption, and more insomnia (p

The aim of this study was to determine whether baseline activity and 1-year change in activity are associated with breast cancer events or mortality..A total of 2,361 post-treatment breast cancer survivors (Stage I-III) enrolled in a randomized controlled trial of dietary change completed physical activity measures at baseline and one year. Physical activity variables (total, moderate-vigorous, and adherence to guidelines) were calculated for each time point. Median follow-up was 7.1 years. Outcomes were invasive breast cancer events and all-cause mortality..Those who were most active at baseline had a 53% lower mortality risk compared to the least active women (HR = 0.47; 95% CI: 0.26, 0.84; p = .01). Adherence to activity guidelines was associated with a 35% lower mortality risk (HR = 0.65, 95% CI: 0.47, 0.91; p < .01). Neither baseline nor 1-year change in activity was associated with additional breast cancer events..Higher baseline (post-treatment) physical activity was associated with improved survival. However, change in activity over the following year was not associated with outcomes. These data suggest that long-term physical activity levels are important for breast cancer prognosis.

Efforts to increase F/V intake include behavior-based interventions. A systematic review of MEDLINE PubMed and PsycINFO databases (2005-2010) was conducted to identify behavior-based intervention trials designed to promote F/V intake. Using predetermined limits and selection criteria, 34 studies were identified for inclusion. Behavior-based interventions resulted in an average increase in F/V intake of +1.13 and +0.39 servings per day in adults and children, respectively. Interventions involving minority adults or low-income participants demonstrated average increases in daily F/V consumption of +0.97 servings/day, whereas worksite interventions averaged +0.8 servings/day. Achieving and sustaining F/V intake at recommended levels of intake across the population cannot be achieved through behavior-based interventions alone. Thus, efforts to combine these interventions with other approaches including social marketing, behavioral economics approaches, and technology-based behavior change models should be tested to ensure goals are met and sustained.

Cox regression models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for invasive CRC by race/ethnicity..The study sample included 131,481 (83.7%) White, 14,323 (9.1%) African-American, 6,362 (4.1%) Hispanic, 694 (0.4%) Native American and 4,148 (2.6%) Asian/Pacific Islanders. After a mean follow-up of 10.8 years (SD 2.9), CRC incidence was the highest in African-Americans (annualized rate = 0.14%), followed by Whites and Native Americans (0.12% each), Asian/Pacific Islanders (0.10%), and Hispanics (0.08%). After adjustment for age and trial assignment, Hispanics had a lower risk compared with Whites, HR 0.73 (95% CI: 0.54-0.97) (P = 0.03), and African-Americans had a marginally greater risk, HR 1.16 (95% CI: 0.99-1.34), P = 0.06.

Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition, 26(5), 512-25. doi:10.1177/0884533611418335More infoObesity, with its comorbidities, is a major public health problem. Population-based surveys estimate 2 of every 3 U.S. adults are overweight or obese. Despite billions of dollars spent annually on weight loss attempts, recidivism is high and long-term results are disappointing. In simplest terms, weight loss and maintenance depend on energy balance, and a combination of increased energy expenditure by exercise and decreased energy intake through caloric restriction is the mainstay of behavioral interventions. Many individuals successfully lose 5%-10% of body weight through behavioral approaches and thereby significantly improve health. Similar success occurs with some weight loss prescriptions, although evidence for successful weight loss with over-the-counter medications and supplements is weak. Commercial weight loss programs have helped many individuals achieve their goals, although few programs have been carefully evaluated and compared, limiting recommendations of one program over another. For the very obese, bariatric surgery is an option that leads to significant weight loss and improved health, although risks must be carefully weighed. Lifestyle changes, including regular physical activity, healthy food choices, and portion control, must be adopted, regardless of the weight loss approach, which requires ongoing support. Patients can best decide the appropriate approach working with a multidisciplinary team, including their health care provider and experts in nutrition, exercise, and behavioral intervention.

Breast cancer research and treatment, 125(2), 519-27. doi:10.1007/s10549-010-1014-9More infoThe protective effect of vegetables on the risk of breast cancer recurrence is uncertain. We sought to evaluate the association between breast cancer recurrence and vegetable intake including analyses stratified on tamoxifen use. Experimental evidence of anti-carcinogenic activity of phytochemicals in cruciferous vegetables in combination with tamoxifen led to specific evaluation of this class of vegetables as well. To assess the association between vegetable intake and breast cancer recurrence, vegetable intake from repeat 24-h dietary recalls were examined as a secondary analysis of 3,080 breast cancer survivors enrolled in the Women's Healthy Eating and Living (WHEL) Study. At the time of enrollment women were, on average, 23.5 months post-diagnosis. The hazard of recurrence, controlling for relevant and significant clinical and demographic variables, with vegetable intake was assessed overall and separately for women taking tamoxifen. WHEL participants reported mean baseline intakes (⁻x, SE) of 3.1 ± 0.05 and 0.5 ± 0.02 servings/day of total and cruciferous vegetables, respectively. Baseline vegetable intake in the highest as compared to lowest tertiles was associated with an overall lower adjusted hazard ratios (HR) for recurrence of 0.69, 95% CI 0.55-0.87. Among women taking tamoxifen, the HRs were 0.56, 95% CI 0.41-0.77 for total vegetables and 0.65, 95% CI 0.47-0.89 for cruciferous vegetable intake. The hazard in women using tamoxifen who reported cruciferous vegetable intake above the median and who were within the highest tertile of total vegetable intake was HR 0.48; 95% CI 0.32-0.70. This secondary analysis in over 3,000 breast cancer survivors suggests that baseline vegetable intake may be associated with a reduction in the risk of breast cancer recurrent or new events particularly for those using tamoxifen. Such associations should be explored further as the possibility that vegetable intake is simply a surrogate for other health-promoting behaviors cannot be ruled out.

American journal of epidemiology, 174(5), 591-603. doi:10.1093/aje/kwr140More infoThe food frequency questionnaire approach to dietary assessment is ubiquitous in nutritional epidemiology research. Food records and recalls provide approaches that may also be adaptable for use in large epidemiologic cohorts, if warranted by better measurement properties. The authors collected (2007-2009) a 4-day food record, three 24-hour dietary recalls, and a food frequency questionnaire from 450 postmenopausal women in the Women's Health Initiative prospective cohort study (enrollment, 1994-1998), along with biomarkers of energy and protein consumption. Through comparison with biomarkers, the food record is shown to provide a stronger estimate of energy and protein than does the food frequency questionnaire, with 24-hour recalls mostly intermediate. Differences were smaller and nonsignificant for protein density. Food frequencies, records, and recalls were, respectively, able to "explain" 3.8%, 7.8%, and 2.8% of biomarker variation for energy; 8.4%, 22.6%, and 16.2% of biomarker variation for protein; and 6.5%, 11.0%, and 7.0% of biomarker variation for protein density. However, calibration equations that include body mass index, age, and ethnicity substantially improve these numbers to 41.7%, 44.7%, and 42.1% for energy; 20.3%, 32.7%, and 28.4% for protein; and 8.7%, 14.4%, and 10.4% for protein density. Calibration equations using any of the assessment procedures may yield suitable consumption estimates for epidemiologic study purposes.

Cancer prevention research (Philadelphia, Pa.), 4(4), 522-9. doi:10.1158/1940-6207.capr-10-0295More infoAlthough studies have shown that physically active breast cancer survivors have lower all-cause mortality, the association between change in physical activity from before to after diagnosis and mortality is not clear. We examined associations among pre- and postdiagnosis physical activity, change in pre- to postdiagnosis physical activity, and all-cause and breast cancer-specific mortality in postmenopausal women. A longitudinal study of 4,643 women diagnosed with invasive breast cancer after entry into the Women's Health Initiative study of postmenopausal women. Physical activity from recreation and walking was determined at baseline (prediagnosis) and after diagnosis (assessed at the 3 or 6 years post-baseline visit). Women participating in 9 MET-h/wk or more (∼ 3 h/wk of fast walking) of physical activity before diagnosis had a lower all-cause mortality (HR = 0.61; 95% CI, 0.44-0.87; P = 0.01) compared with inactive women in multivariable adjusted analyses. Women participating in ≥ 9 or more MET-h/wk of physical activity after diagnosis had lower breast cancer mortality (HR = 0.61; 95% CI, 0.35-0.99; P = 0.049) and lower all-cause mortality (HR = 0.54; 95% CI, 0.38-0.79; P < 0.01). Women who increased or maintained physical activity of 9 or more MET-h/wk after diagnosis had lower all-cause mortality (HR = 0.67; 95% CI, 0.46-0.96) even if they were inactive before diagnosis. High levels of physical activity may improve survival in postmenopausal women with breast cancer, even among those reporting low physical activity prior to diagnosis. Women diagnosed with breast cancer should be encouraged to initiate and maintain a program of physical activity.

Journal of the American Geriatrics Society, 58(12), 2337-44. doi:10.1111/j.1532-5415.2010.03183.xMore infoTo prospectively examine the relationship between anemia and incident fractures of the hip, spine, and all skeletal sites in women from diverse racial and ethnic backgrounds enrolled in the Women's Health Initiative (WHI) Observational Study and Clinical Trials..Prospective cohort study..Forty WHI clinical centers across the United States..Postmenopausal women (n=160,080), mean age 63.2±7.2, were recruited and followed for an average of 7.8 years..Anemia was defined as hemoglobin levels at baseline less than 12 g/dL. All fractures were self-reported. Trained physicians further confirmed hip fractures using medical records..Eight thousand seven hundred thirty-nine of the participants (5.5%) were anemic. The age-adjusted incidence rate of hip fractures per 10,000 person-years was 21.4 in women with anemia and 15.0 in women without anemia; higher incidence rates for spine and all fractures were also observed in anemic women. After multiple covariates were included in the Cox proportional hazards models, significantly greater fracture risk associated with anemia still existed, as demonstrated by hazard ratios of fractures associated with anemia of 1.38 (95% confidence interval (CI)=1.13-1.68) for hip, 1.30 (95% CI=1.09-1.55) for spine, and 1.07 (95% CI=1.01-1.14) for all types. No significant racial or ethnic difference was found in these relationships..A significantly greater fracture risk was observed in multiethnic postmenopausal women with anemia. Given the high prevalence of anemia in the elderly population, it is important to better understand the relationship and mechanisms linking anemia to fracture risk.

Abstract A119: Effect of weight‐bearing exercise on circulating biomarkers in breast cancer survivors. Cancer Prevention Research, 3. doi:10.1158/1940-6207.prev-09-a119More infoBreast cancer patients generally demonstrate a gain in body fat mass accompanied by loss of lean mass (i.e. muscle) during cancer therapy (Demark‐Wahnefried et al, J. Clin Oncol, 2001). These changes may lead to adverse metabolic and inflammatory phenotypes. The objective of this pilot study was to evaluate changes in metabolic, inflammatory, and growth factor biomarkers among breast cancer survivors following 8 weeks of supervised resistance training combined with self‐reported cardiovascular training. No diet or weight loss component was included in the intervention. Twenty‐seven breast cancer survivors (78.3% Caucasian, mean age 56.5 ± 8.1 yrs, mean BMI 29.8 ± 4.4kg/m 2 ) who were on average 5 years post‐cancer treatment were recruited to participate in a prospective behavioral intervention trial to test the hypothesis that weight bearing activity including stretching, resistance, balance, and aerobic training would improve select metabolic and inflammatory indicators over an 8 week period. Height, weight, body composition (dual X‐ray absorptiometry), fasting plasma glucose, insulin, IL‐6, CRP, IL‐1Ra, and IGF‐1 were measured at baseline and 8 weeks. IL‐6, IL‐1Ra and IGF‐1 were analyzed using high sensitivity ELISA and glucose was measured by a glucose oxidase‐peroxide reaction; insulin and CRP testing were performed by the local hospital clinical laboratory. The homeostasis model of insulin resistance was computed (HOMA‐IR) from glucose and insulin values. Eighty‐one percent of the sample completed the 8‐week intervention. Among completers (n=22) there was no significant change in body weight. Inflammatory response, as assessed using IL‐1Ra, was improved (76.75 ± 161.39, p Breast cancer survivors participating in a pilot, short‐term structured physical activity intervention targeting resistance training, in the absence of diet or weight change, demonstrated a significant improvement in the anti‐inflammatory biomarker IL‐1Ra without concomitant increases in pro‐inflammatory biomarkers, IL‐6 and CRP. Larger studies with sufficient sample size to detect statistically significant differences should be pursued; combining structured exercise with diet to support weight reduction may also be superior and should be evaluated.

Green tea has been proposed to promote weight loss and favourably modify glucose, insulin and blood lipids. This pilot study tested the effect of daily decaffeinated green tea consumption for 6 months on weight and body composition, select metabolic parameters and lipid profiles in overweight breast cancer survivors..The effect of daily decaffeinated green tea intake on weight, body composition and changes in resting metabolic rate, energy intake, glucose, insulin, homeostasis model assessment--insulin resistance (HOMA-IR) and lipids was evaluated in overweight breast cancer survivors. Participants had a mean weight of 80.2 kg; body mass index (BMI) 30.1 kg m⁻²; and body fat 46.4%. Participants (n = 54) were randomised to 960 mL of decaffeinated green or placebo tea daily for 6 months..Mean (SD) tea intake among study completers (n = 39) was 5952 (1176) mL week⁻¹ and was associated with a significant reduction in energy intake (P = 0.02). Change in body weight of -1.2 kg (green tea) versus +0.2 kg (placebo) suggests a weight change effect, although this was not statistically significant. Decaffeinated green tea intake was associated with elevated high-density lipoprotein (HDL) levels (P = 0.003) and nonsignificant improvements in the HDL/LDL ratio and HOMA-IR (-1.1 ± 5.9: green tea; +3.2 ± 7.2: herbal)..Intake of decaffeinated green tea for 6 months was associated with a slight reduction in body weight and improved HDL and glucose homeostasis in overweight breast cancer survivors.

Nutrition and cancer, 62(6), 783-8. doi:10.1080/01635581003693066More infod-limonene is a bioactive food component found in high concentration in citrus peel oil with anticancer effects in preclinical studies of mammary carcinogenesis. Extrapolation of preclinical data to human cancer is limited, in part, by inadequate information on the oral bioavailability and tissue disposition of d-limonene in humans. As a fat-soluble compound, d-limonene is more likely to deposit in fatty tissues such as the breast. To assess disposition of d-limonene in humans, we conducted a pilot study of oral d-limonene-rich lemonade. Following a 1-wk washout period devoid of citrus, healthy adults consumed 40 oz. of freshly prepared lemonade containing 500 to 600 mg d-limonene daily for 4 wk. On the first and last consumption days, blood and buttock fat biopsy were collected. Matched preintervention and postintervention fat biopsies (n = 7), and matched preintervention and postintervention plasma samples (n = 6), were analyzed for d-limonene levels using gas chromatography and mass spectrometry. There was a significant increase in d-limonene levels in the fat biopsies after 4 wk (P = 0.009); initial levels ranged from nondetectable to 7.79 micromol/kg tissue, and postintervention levels ranged from 53.6 to 294 micromol/kg tissue. Plasma d-limonene levels increased from 0.35 to 0.72 micromol/l initially to postintervention levels of 0.54 to 1.65 micromol/l (P = 0.016). Postintervention adipose d-limonene levels were 51.0 to 195 times higher than plasma levels (P = 0.009). Our results demonstrate accumulation of d-limonene in adipose tissue after oral dosing and support additional studies of d-limonene for chemoprevention in tissues such as the breast that are comprised of a significant fat fraction.

An inverse association between alcohol intake and obesity suggests possible confounding between these variables (and perhaps other factors) with breast cancer outcomes..Alcohol intake (beer, wine, spirits, and total) was examined in 3,088 women previously diagnosed and treated for breast cancer within an intervention trial that targeted vegetables, fiber, and fat but not alcohol or weight loss. Factors associated with baseline alcohol intake were included in Cox proportional hazards models for recurrence and mortality..Alcohol intake was significantly associated with higher education and physical activity levels. Neither light alcohol intake nor obesity was significantly associated with breast cancer recurrence, but moderate alcohol intake >300 g/mo was protective against all-cause mortality (hazard ratio, 0.69; 95% confidence intervals, 0.49-0.97) in a proportional hazards model adjusted for obesity. Obese women were 61% more likely to be nondrinkers than drinkers, and 76% more likely to be light drinkers than moderate/heavy drinkers. In nonobese women, alcohol intake >10 g/mo was associated with lower risk of all-cause mortality (hazard ratio, 0.68; 95% confidence intervals, 0.51-0.91)..Light alcohol intake, regardless of body weight, did not increase the risk of breast cancer recurrence or all-cause mortality in this cohort of middle-aged women previously diagnosed with breast cancer. Alcohol intake was associated with other favorable prognostic indicators, which may explain its apparent protective effect in nonobese women.

Measurement error of dietary self-report in intervention trials.. American journal of epidemiology, 172(7), 819-27. doi:10.1093/aje/kwq216More infoDietary intervention trials aim to change dietary patterns of individuals. Participating in such trials could impact dietary self-report in divergent ways: Dietary counseling and training on portion-size estimation could improve self-report accuracy; participant burden could increase systematic error. Such intervention-associated biases could complicate interpretation of trial results. The authors investigated intervention-associated biases in reported total carotenoid intake using data on 3,088 breast cancer survivors recruited between 1995 and 2000 and followed through 2006 in the Women's Healthy Eating and Living Study, a randomized intervention trial. Longitudinal data from 2 self-report methods (24-hour recalls and food frequency questionnaires) and a plasma carotenoid biomarker were collected. A flexible measurement error model was postulated. Parameters were estimated in a Bayesian framework by using Markov chain Monte Carlo methods. Results indicated that the validity (i.e., correlation with "true" intake) of both self-report methods was significantly higher during follow-up for intervention versus nonintervention participants (4-year validity estimates: intervention = 0.57 for food frequency questionnaires and 0.58 for 24-hour recalls; nonintervention = 0.42 for food frequency questionnaires and 0.48 for 24-hour recalls). However, within- and between-instrument error correlations during follow-up were higher among intervention participants, indicating an increase in systematic error. Diet interventions can impact measurement errors of dietary self-report. Appropriate statistical methods should be applied to examine intervention-associated biases when interpreting results of diet trials.

Breast cancer research and treatment, 122(3), 859-65. doi:10.1007/s10549-010-0732-3More infoThis analysis was conducted to determine whether comorbid medical conditions predict additional breast cancer events and all-cause mortality in women with a history of early stage breast cancer. Women (n = 2,542) participating in a randomized diet trial completed a self-administered questionnaire regarding whether they were currently being treated for a wide variety of diseases (cardiovascular, diabetes, gallbladder, gastrointestinal, arthritis, and osteoporosis) and conditions (high blood pressure, elevated cholesterol level). Height and weight were measured at baseline. Participants were followed for a median of 7.3 years (range 0.8-15.0). Cox regression analysis was performed to assess whether comorbidities predicted disease-free and overall survival; hazard ratio (HR) was the measure of association. Overall, there were 406 additional breast cancer events and 242 deaths. Participants with diabetes had over twofold the risk of additional breast cancer events (HR 2.1, 95% CI: 1.3, 3.4) and mortality (HR 2.5, 95% CI: 1.4, 4.4). The presence of multiple comorbidities did not statistically significantly predict additional breast cancer events. However, compared to no comorbidities, participants with 3 or more comorbidities had a HR of 2.1, 95% CI: 1.3, 3.3 for mortality. In conclusion, type 2 diabetes is associated with poor breast cancer prognosis. Given that 85% of deaths were caused by breast cancer, these findings suggest that multiple comorbidities may reduce the likelihood of surviving additional breast cancer events.

Abstract A111: Sweetened beverages, sweetened foods, glycemic load, and breast cancer recurrence. Cancer Prevention Research, 3. doi:10.1158/1940-6207.prev-09-a111More infoBackground: The role of sweetened food and beverage intake in breast cancer recurrence has been largely unexplored despite mechanistic evidence that these dietary factors may be associated with elevated glycemic load, insulin levels and proinflammatory response. Objective: To assess risk for recurrent or a new primary breast cancer event among 2832 breast cancer survivors enrolled in the Women9s Healthy Eating and Living (WHEL) Study in relation to baseline sweetened beverage and sweetened food intakes and glycemic index/glycemic load. Design: Prospective sub-group analysis of dietary GI, GL, white bread/rolls/crackers, sweet food and sweetened beverage intakes, as assessed using the Arizona Food Frequency Questionnaire (AFFQ), and new breast cancer events (N=471). Descriptive statistics and Cox regression analysis, adjusted for confounding variables, were performed to assess hazard ratio for recurrence risk by dietary exposure. Results: Study subjects consumed, on average, 281.7±111.4 g/d carbohydrate (CHO) and 25.2±12.3 g/d of dietary fiber and had an estimated GL of 129.5±52.2.While GI and GL were not significantly associated with breast cancer events, postmenopausal women who reported a higher intake of sweetened beverages demonstrated a significant elevation in risk for recurrent disease (HR 1.46; 95% CI,1.07–1.98). Intake of sweetened beverages was greater among minority women and was associated with higher body mass index and lower reported physical activity suggesting sweetened beverage intake may be a surrogate of other risk factors. Conclusions: High intake of sweetened beverages, including carbonated beverages and sweetened fruit drinks, is associated with an increased risk for breast cancer recurrence among postmenopausal women previously treated for early stage disease.

Nutrition and cancer, 62(8), 1142-52. doi:10.1080/01635581.2010.513803More infoOverweight status is common among women breast cancer survivors and places them at greater risk for metabolic disorders, cardiovascular morbidity, and breast cancer recurrence than nonoverweight survivors. Efforts to promote weight control in this population are needed. The objective of this research was to evaluate the effect of low-fat or low-carbohydrate diet counseling on weight loss, body composition, and changes in metabolic indexes in overweight postmenopausal breast cancer survivors. Survivors (n = 40) were randomized to receive dietitian counseling for a low-fat or a reduced carbohydrate diet for 6 mo. Weight and metabolic measures, including glucose, insulin, HbA1c, HOMA, lipids, hsCRP, as well as blood pressure were measured at baseline, 6, 12 and 24 wk. Dietary intake of fat and carbohydrate was reduced by 24 and 76 g/day, respectively. Weight loss averaged 6.1 (± 4.8 kg) at 24 wk and was not significantly different by diet group; loss of lean mass was also demonstrated. All subjects demonstrated improvements in total/HDL cholesterol ratio, and significant reductions in HbA1c, insulin, and HOMA. Triglycerides levels were significantly reduced only in the low-carbohydrate diet group (-31.1 ± 36.6; P = 0.01). Significant improvements in weight and metabolic indexes can be demonstrated among overweight breast cancer survivors adherent to either a carbohydrate- or fat-restricted diet.

Menopause (New York, N.Y.), 17(6), 1152-60. doi:10.1097/gme.0b013e3181e102d9More infoDietary intake of vitamin D and calcium may be related to risk of breast cancer, possibly by affecting mammographic density. However, the few studies that have evaluated the association between these nutrients and mammographic density in postmenopausal women have had inconsistent results..We conducted a cross-sectional analysis in 808 participants of the Mammogram Density Ancillary Study of the Women's Health Initiative. Mammographic percent density was measured using baseline mammograms taken before randomization of participants in the intervention trials. Vitamin D and calcium intake was assessed with a validated food frequency questionnaire and an inventory of current supplement use, both completed at baseline..After adjustment for age, body mass index, regional solar irradiance, and other factors, we did not find a relationship between vitamin D or calcium intake and mammographic density. Mean mammographic percent densities in women reporting total vitamin D intakes of less than 100, 100 to 199, 200 to 399, 400 to 599, and 600 or greater IU/day were 5.8%, 10.4%, 6.2%, 3.8%, and 5.1%, respectively (P trend = 0.67). Results in women reporting a total calcium intake of less than 500, 500 to 749, 750 to 999, 1,000 to 1,199, and 1,200 or greater mg/day were 7.3%, 4.9%, 7.3%, 6.9%, and 7.11%, respectively (P trend = 0.51). We did not observe any effect modification by overall level of mammographic density or solar irradiance, but supplemental vitamin D use was associated with lower density in younger women (P interaction = 0.009)..These findings do not support a relationship between dietary vitamin D or calcium intake and mammographic density in postmenopausal women. Additional studies should explore these associations in women of different ages and in relation to serum vitamin D levels.

Commercial weight loss programs may contribute to efforts to reduce the prevalence of overweight and obesity, although few studies have examined their efficacy in controlled trials..To test whether a free prepared meal and incentivized structured weight loss program promotes greater weight loss and weight loss maintenance at 2 years compared with usual care..A randomized controlled trial of weight loss and weight loss maintenance in 442 overweight or obese women (body mass index, 25-40) aged 18 to 69 years (mean age, 44 years) conducted at US institutions over 2 years with follow-up between November 2007 and April 2010..The program, which involves in-person center-based or telephone-based one-to-one weight loss counseling, was available over a 2-year period. Behavioral goals were an energy-reduced, nutritionally adequate diet, facilitated by the inclusion of prepackaged food items in a planned menu during the initial weight loss phase, and increased physical activity. Participants assigned to usual care received 2 individualized weight loss counseling sessions with a dietetics professional and monthly contacts..Weight loss and weight loss maintenance..Weight data were available at 24 months for 407 women (92.1% of the study sample). In an intent-to-treat analysis with baseline value substitution, mean weight loss was 7.4 kg (95% confidence interval [CI], 6.1-8.7 kg) or 7.9% (95% CI, 6.5%-9.3%) of initial weight at 24 months for the center-based group, 6.2 kg (95% CI, 4.9-7.6 kg) or 6.8% (95% CI, 5.2%-8.4%) for the telephone-based group, and 2.0 kg (95% CI, 0.6-3.3 kg) or 2.1% (95% CI, 0.7%-3.5%) for the usual care control group after 24 months (P < .001 for intervention effect)..Compared with usual care, this structured weight loss program resulted in greater weight loss over 2 years..clinicaltrials.gov Identifier: NCT00640900.

Pilot study on the effects of dietary conjugated linoleic acid on tumorigenesis and gene expression in PyMT transgenic mice.. Carcinogenesis, 31(9), 1642-9. doi:10.1093/carcin/bgq148More infoConjugated linoleic acid (CLA) is a class of commercially available fatty acids that have been associated with anticancer properties in rodent models of chemical carcinogenesis. We conducted a pilot study to examine the antitumor effect of dietary CLA in a polyoma virus-middle T antigen (PyMT) mouse model of invasive breast cancer. Virgin 4-week-old PyMT mice were administered a mixed-isomer CLA diet (1% wt/wt) or control AIN-93G diet for 4 weeks (N = 6 and 5, respectively) and tumor burden was assessed at 8 weeks of age. Thoracic mammary glands were prepared as whole mounts with other glands being formalin fixed and paraffin embedded for histology and immunohistochemistry (IHC). Total RNA was prepared for microarray and real-time reverse transcription-polymerase chain reaction analysis. Western blots were performed for protein expression analysis. Tumor incidence was significantly increased in CLA-treated animals compared with controls (P = 0.009) and occurred with extensive lobular-alveolar expansion and loss of mammary adipose tissue. More than 100 genes were downregulated > or = 2-fold in the CLA-treated group compared with controls, including adipose-specific markers, as wells as cytoskeletal and adhesion-related genes. This was supported by dramatic decreases in the epithelial adherens E-cadherin and beta-catenin as demonstrated by IHC. Taken together, these results suggest that dietary CLA affects the mammary stromal environment, leading to tumor progression and cellular expansion in the PyMT mouse model. Further studies of the potential for cancer promotion are needed, especially because mixed-isomer CLA formulations are sold commercially as a nutritional supplement.

Cancer causes & control : CCC, 21(2), 223-36. doi:10.1007/s10552-009-9453-5More infoWe hypothesized that intentional weight loss may be associated with development of lymphohematopoietic cancers, based on observations of immune suppression following weight loss in short-term studies..At the baseline of the Women's Health Initiative Observational Study (1994-1998), participants reported information about intentional weight loss episodes in the past 20 years. We estimated hazard ratios (HRs) and 95% confidence intervals (CIs) among 81,219 women for associations between past intentional weight loss and risk of developing non-Hodgkin lymphoma (NHL), leukemia, and multiple myeloma during an average 9.9 years of follow-up..The risk of NHL was associated with having lost a large maximum amount of weight (> or =50 pounds, HR = 1.68, 95% CI 1.13-2.50). NHL risk also varied by the frequency of intentional weight loss; women had increased risk if they lost 50 pounds or more > or =3 times (HR = 1.97, 95% CI 0.93-4.16; p trend by frequency = 0.09) or 20-49 pounds > or =3 times (HR = 1.55, 95% CI 1.00-2.40; p trend = 0.05), but there was no risk associated with smaller amounts of weight loss (10-19 pounds > or =3 times, HR = 0.78, 95% CI 0.46-1.33). These associations persisted with adjustment for body mass index at different ages. We observed non-significant associations of similar magnitude for multiple myeloma, but past intentional weight loss episodes were not associated with leukemia..Further assessment of intentional weight loss as a possible risk factor for lymphomas may provide insight into the etiology of these cancers.

Journal of the American Dietetic Association, 109(5), 899-904. doi:10.1016/j.jada.2009.02.008More infoIt is important to identify the role of nutrition in the treatment and prevention of osteoporosis. The goal of this study was to compare the equivalency of nutrient intakes assessed by diet records and the Arizona Food Frequency Questionnaire and the associations of these nutrients with bone mineral density (BMD). This is a secondary analysis of cross-sectional data that was analyzed from six cohorts (fall 1995 to fall 1997) of postmenopausal women (n=244; 55.7+/-4.6 years) participating in a 12-month, block-randomized, clinical trial. One-year dietary intakes were assessed using 8 days of diet records and the Arizona Food Frequency Questionnaire. Participants' BMD was measured at the lumbar spine (L2-L4), femur trochanter, femur neck, Ward's triangle, and total body using dual-energy x-ray absorptiometry. Linear regression analyses (P< or =0.05) were adjusted for the effects of exercise, hormone therapy use, body weight at 1 year, years post menopause, and total energy intake. Significant correlations (r=0.30 to 0.70, P< or =0.05) between dietary assessment methods were found with all dietary intake variables. Iron and magnesium were consistently and significantly positively associated with BMD at all bone sites regardless of the dietary assessment method. Zinc, dietary calcium, phosphorous, potassium, total calcium, and fiber intakes were positively associated with BMD at three or more of the same bone sites regardless of the dietary assessment method. Protein, alcohol, caffeine, sodium, and vitamin E did not have any similar BMD associations.

Carotenoids are obtained primarily from vegetables and fruit and they exhibit biological activities that may specifically reduce the progression of mammary carcinogenesis. The present analysis examines the relationship between plasma carotenoids at enrollment and 1, 2 or 3, 4, and 6 years and breast cancer-free survival in the Women's Healthy Eating and Living Study participants (N = 3,043), who had been diagnosed with early-stage breast cancer. The primary end point was time to a second breast cancer event (a recurrence or new primary breast cancer). An average carotenoid concentration over time was estimated for each participant as the average area under the plasma carotenoid curve formed by the plasma carotenoid concentrations at scheduled clinic visits. Multiple regression Cox proportional hazards analysis with adjustment for prognostic and other factors was used to examine the association between carotenoids and breast cancer-free survival. A total of 508 (16.7%) breast cancer events occurred over a median 7.12 years follow-up. Compared with the lowest tertile, the hazard ratio for the medium/high plasma carotenoid tertiles was 0.67 (95% confidence interval, 0.54-0.83) after adjustment. The interaction between the study group and tertile of average carotenoid concentration over time was not significant (P = 0.23). Higher biological exposure to carotenoids, when assessed over the time frame of the study, was associated with greater likelihood of breast cancer-free survival regardless of study group assignment.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 27(3), 352-9. doi:10.1200/jco.2008.16.1067More infoTo determine whether a low-fat diet high in vegetables, fruit, and fiber differentially affects prognosis in breast cancer survivors with hot flashes (HF) or without HF after treatment..A secondary analysis was conducted on 2,967 breast cancer survivors, age 18 to 70 years, who were randomly assigned between 1995 and 2000 in a multicenter, controlled trial of a dietary intervention to prevent additional breast cancer events and observed through June 1, 2006. We compared the dietary intervention group with a group who received five-a-day dietary guidelines..Independent of HF status, a substantial between-group difference among those who did and did not receive dietary guidelines was achieved and maintained at 4 years in intake of vegetable/fruit servings per day (54% higher; 10 v 6.5 servings/d, respectively), fiber (31% higher; 25.5 v 19.4 g/d, respectively), and percent energy from fat (14% lower; 26.9% v 31.3%, respectively). Adjusting for tumor characteristics and antiestrogen treatment, HF-negative women assigned to the intervention had 31% fewer events than HF-negative women assigned to the comparison group (hazard ratio [HR] = 0.69; 95% CI, 0.51 to 0.93; P = .02). The intervention did not affect prognosis in the women with baseline HFs. Furthermore, compared with HF-negative women assigned to the comparison group, HF-positive women had significantly fewer events in both the intervention (HR = 0.77; 95% CI, 0.59 to 1.00; P = .05) and comparison groups (HR = 0.65; 95% CI, 0.49 to 0.85; P = .002)..A diet with higher vegetable, fruit, and fiber and lower fat intakes than the five-a-day diet may reduce risk of additional events in HF-negative breast cancer survivors. This suggestive finding needs confirmation in a trial in which it is the primary hypothesis.

The intervention change was associated with a significant increase of $1.22/ person/week (multivariate model, P=0.027)..A major change to a plant-based diet was associated with a minimal increase in grocery costs.

American journal of epidemiology, 169(12), 1463-70. doi:10.1093/aje/kwp077More infoEarly detection and effective treatments have dramatically improved breast cancer survivorship, yet the risk of relapse persists even 15 years after the initial diagnosis. It is important to identify prognostic factors for late breast cancer events. The authors investigated time-varying effects of tumor characteristics on breast-cancer-free survival using data on 3,088 breast cancer survivors from 4 US states who participated in a randomized dietary intervention trial in 1995-2006, with maximum follow-up through 15 years (median, 9 years). A piecewise constant penalized spline approach incorporating time-varying coefficients was adopted, allowing for deviations from the proportional hazards assumption. This method is more flexible than standard approaches, provides direct estimates of hazard ratios across time intervals, and is computationally tractable. Having a stage II or III tumor was associated with a 3-fold higher hazard of breast cancer than having a stage I tumor during the first 2.5 years after diagnosis; this hazard ratio decreased to 2.1 after 7.7 years, but higher tumor stage remained a significant risk factor. Similar diminishing effects were found for poorly differentiated tumors. Interestingly, having a positive estrogen receptor status was protective up to 4 years after diagnosis but detrimental after 7.7 years (hazard ratio = 1.5). These results emphasize the importance of careful statistical modeling allowing for possibly time-dependent effects in long-term survivorship studies.

Participants did not experience hot flashes at baseline (n = 896). We confirmed cancer status for 96% of participants approximately 7.3 y after enrollment..The study intervention achieved a large between-group difference in dietary pattern that, at 4 y, was not significantly different across baseline quartiles of dietary pattern. The intervention group experienced fewer breast cancer events than did the comparison group for all of the baseline quartiles. This difference was significant only in upper baseline quartiles of intake of vegetables, fruit, and fiber and in the lowest quartile of fat. A significant trend for fewer breast cancer events was observed across quartiles of vegetable-fruit and fiber consumption..The secondary analysis showing the decreased risk in the HF- subgroup was not explained by amount of change in dietary pattern achieved. The difference was strongest in the quartile with the most putatively cancer-preventive dietary pattern at baseline.

Participants were 1,510 breast cancer survivors with BMI > or = 25 kg/m(2) at entry. Dietary intake was assessed yearly by telephone; weight and height were measured at clinic visits. Intervention participants consumed more fruit, vegetables, and fiber and less energy from fat than control participants during follow-up cross-sectionally (p < .0001) and longitudinally (p < .0001); weight did not differ between study groups at any follow-up visit, and significant weight change difference was observed between groups only in the 1st year (p < .0001). Diet and weight results remained unchanged after stratifying by age and BMI. No difference in obesity incidence was found during follow-up (p > .10) among overweight members of either study group. Without specific efforts to reduce total energy intake, dietary modification does not reduce obesity or result in long-term weight loss.

Journal of women's health (2002), 18(12), 2041-7. doi:10.1089/jwh.2009.1365More infoAs the efficacy of treatment for breast cancer has improved, particularly with the use of antiestrogenic therapies, there is an increasing population of long-term breast cancer survivors who seeks care with unique health issues. These patients may be at increased risk for cardiovascular disease (CVD) resulting from excess adiposity and treatment effects. Metabolic syndrome (MetS) and elevated C-reactive protein (CRP), two predictors of CVD, have not been fully evaluated in overweight breast cancer survivors on hormone-modulating agents..Anthropometric measures, including weight, height, waist and hip circumferences; clinical laboratory assessments, including lipids, glucose, glycoslyated hemoglobin (HbA1c), insulin, and high sensitivity CRP; and body composition and blood pressure (BP) were collected from overweight breast cancer survivors (n=42). Select measures were used to derive MetS using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) diagnostic criteria..Participants had a mean body weight of 83.8 kg and body mass index (BMI) of 31.4 kg/m2. Mean fasting glucose (98+/-12.9 mg/dL), HbA1c (6.0+/-0.5 mg/dL), cholesterol (199+/-33.7 mg/dL), and insulin (16+/-3.2 mg/dL) were all at the upper end of the normal range. MetS was diagnosed in 54.8% of overweight postmenopausal breast cancer survivors. CRP was moderately or severely elevated in 90.5% of the population (mean of 5.1+/-5.3 mg/dL)..In our sample, overweight breast cancer survivors commonly have MetS and elevated CRP that place them at increased risk for cardiovascular and other metabolic diseases. If replicated in a larger sample, this warrants close medical monitoring to prevent and reduce morbidity and mortality unrelated to breast cancer.

Future oncology (London, England), 5(8), 1257-69. doi:10.2217/fon.09.86More infoSurvival in women diagnosed with early-stage, invasive breast cancer has improved dramatically in the past 10-15 years. This is largely due to the use of pharmacological therapies targeting a reduction in estrogen action and exposure. Women diagnosed with breast cancer often alter their eating behavior towards healthier food choices in an attempt to improve their survival and their overall health and well being. Mounting interest in the role of diet to modify breast cancer survival and/or comorbidity and mortality has led researchers to evaluate the effects of differential dietary patterns on this disease. Current findings suggest a possible, but inconsistent, benefit of a prudent, vegetable-rich, low-fat/high-vegetable eating pattern on disease-free survival, but the results to date are limited by strong treatment effectiveness and low overall recurrence rates. It is more likely this prudent eating pattern will improve non-breast cancer mortality (e.g., cardiovascular disease) compared with a Western dietary pattern. Efforts to educate women diagnosed with breast cancer to consume a diet lower in total and saturated fat, higher in vegetables and fiber, and which results in mild to modest weight loss among overweight/obese women is sensible in light of the high survivability of breast cancer and need to direct attention to comorbidities that likely increase as a consequence of treatment and treatment-related weight gain and sedentary behavior. Additional research is needed to address the importance of diet in the breast cancer patient, particularly in relation to the effect of select dietary patterns on factors that influence individual recurrence risk (e.g., hormone levels, drug metabolism and oxidative stress), as well as factors that influence non-breast cancer morbidity risk and causes of death in the survivor population.

Several studies have examined the association of the individual components of the metabolic syndrome with breast cancer; to date, however, no study has assessed the metabolic syndrome per se in relation to breast cancer risk. Furthermore, previous studies have relied only on baseline assessment of components of the syndrome. Therefore, we assessed the association of the metabolic syndrome with the risk of postmenopausal breast cancer among women in the 6% sample of subjects in the Women's Health Initiative clinical trial and the 1% sample of women in the observational study who had repeated measurements of the components of the syndrome during follow-up. We used Cox proportional hazards models to estimate hazard ratios and 95% confidence intervals for the association of breast cancer risk with the presence of the metabolic syndrome, as well as its components, at baseline and in time-dependent analyses. After exclusion of women with diabetes, among 4,888 women with baseline measurements, 165 incident cases of breast cancer were ascertained over a median of 8 years of follow-up. The presence of the metabolic syndrome at baseline was not associated with altered risk. Of the individual components measured at baseline, diastolic blood pressure showed a borderline positive association with breast cancer. In time-dependent covariate analyses, however, certain scenarios indicated a positive association between the metabolic syndrome and breast cancer, due primarily to positive associations with serum glucose, serum triglycerides, and diastolic blood pressure.

American journal of epidemiology, 169(8), 977-89. doi:10.1093/aje/kwp008More infoThe authors previously reported equations, derived from the Nutrient Biomarker Study within the Women's Health Initiative, that produce calibrated estimates of energy, protein, and percentage of energy from protein consumption from corresponding food frequency questionnaire estimates and data on other factors, such as body mass index, age, and ethnicity. Here, these equations were applied to yield calibrated consumption estimates for 21,711 women enrolled in the Women's Health Initiative dietary modification trial comparison group and 59,105 women enrolled in the observational study. These estimates were related prospectively to total and site-specific invasive cancer incidence (1993-2005). In combined cohort analyses that do not control for body mass, uncalibrated energy was not associated with total cancer incidence or site-specific cancer incidence for most sites, whereas biomarker-calibrated energy was positively associated with total cancer (hazard ratio = 1.18, 95% confidence interval: 1.10, 1.27, for 20% consumption increase), as well as with breast, colon, endometrial, and kidney cancer (respective hazard ratios of 1.24, 1.35, 1.83, and 1.47). Calibrated protein was weakly associated, and calibrated percentage of energy from protein was inversely associated, with total cancer. Calibrated energy and body mass index associations were highly interdependent. Implications for the interpretation of nutritional epidemiology studies are described.

Presence of vasomotor symptoms at baseline was ascertained from a 34-item self-report symptom inventory. Women were queried semi-annually for a new diagnosis of breast cancer. Each case report was verified by medical record and pathology report review by centrally trained WHI physician adjudicators..Among participants who reported hot flashes (HFs) at baseline (n = 3,375), those assigned to the low-fat diet had a breast cancer rate of 0.27 compared with their counterparts in the control group who had a rate of 0.41 (hazard ratio [HR] = 0.65; 95% CI, 0.42 to 1.01). Among women reporting no HFs (n = 45,160), the breast cancer rate was 0.42 in those assigned to the low-fat diet compared with 0.46 in the control group (HR = 0.93; 95% CI, 0.84 to 1.03; P for interaction = .12 by HF status). Furthermore, the dietary benefits observed seemed to be specific to estrogen receptor (ER) -positive/progesterone receptor (PR) -positive tumors (ER positive/PR positive v other, P for risk = .03). Although women with and without HFs differed with regard to breast cancer risk factors, the effect of the diet intervention on breast cancer incidence by HF status was consistent across risk factor strata..The results of this trial, which are hypothesis generating, suggest that HFs may identify a subgroup of postmenopausal women whose risk of invasive breast cancer might be reduced with the adoption of a low-fat eating pattern.

Archives of internal medicine, 169(3), 294-304. doi:10.1001/archinternmed.2008.540More infoMillions of postmenopausal women use multivitamins, often believing that supplements prevent chronic diseases such as cancer and cardiovascular disease (CVD). Therefore, we decided to examine associations between multivitamin use and risk of cancer, CVD, and mortality in postmenopausal women..The study included 161 808 participants from the Women's Health Initiative clinical trials (N = 68 132 in 3 overlapping trials of hormone therapy, dietary modification, and calcium and vitamin D supplements) or an observational study (N = 93 676). Detailed data were collected on multivitamin use at baseline and follow-up time points. Study enrollment occurred between 1993 and 1998; the women were followed up for a median of 8.0 years in the clinical trials and 7.9 years in the observational study. Disease end points were collected through 2005. We documented cancers of the breast (invasive), colon/rectum, endometrium, kidney, bladder, stomach, ovary, and lung; CVD (myocardial infarction, stroke, and venous thromboembolism); and total mortality..A total of 41.5% of the participants used multivitamins. After a median of 8.0 years of follow-up in the clinical trial cohort and 7.9 years in the observational study cohort, 9619 cases of breast, colorectal, endometrial, renal, bladder, stomach, lung, or ovarian cancer; 8751 CVD events; and 9865 deaths were reported. Multivariate-adjusted analyses revealed no association of multivitamin use with risk of cancer (hazard ratio [HR], 0.98, and 95% confidence interval [CI], 0.91-1.05 for breast cancer; HR, 0.99, and 95% CI, 0.88-1.11 for colorectal cancer; HR, 1.05, and 95% CI, 0.90-1.21 for endometrial cancer; HR, 1.0, and 95% CI, 0.88-1.13 for lung cancer; and HR, 1.07, and 95% CI, 0.88-1.29 for ovarian cancer); CVD (HR, 0.96, and 95% CI, 0.89-1.03 for myocardial infarction; HR, 0.99, and 95% CI, 0.91-1.07 for stroke; and HR, 1.05, and 95% CI, 0.85-1.29 for venous thromboembolism); or mortality (HR, 1.02, and 95% CI, 0.97-1.07)..After a median follow-up of 8.0 and 7.9 years in the clinical trial and observational study cohorts, respectively, the Women's Health Initiative study provided convincing evidence that multivitamin use has little or no influence on the risk of common cancers, CVD, or total mortality in postmenopausal women.

This report details the concept, content, and implementation of the low-fat eating plan used in the dietary intervention group of this trial. Intervention group participants were given a daily fat gram goal. The intervention was delivered by centrally trained, registered dietitians who applied behavioral, cognitive, and motivational counseling techniques.

We examined the effect of calcium plus vitamin D supplementation on blood pressure and the incidence of hypertension in postmenopausal women. The Women's Health Initiative Calcium/Vitamin D Trial randomly assigned 36 282 postmenopausal women to receive 1000 mg of elemental calcium plus 400 IU of vitamin D3 daily or placebo in a double-blind fashion. Change in blood pressure and the incidence of hypertension were ascertained. Over a median follow-up time of 7 years, there was no significant difference in the mean change over time in systolic blood pressure (0.22 mm Hg; 95% CI: -0.05 to 0.49 mm Hg) and diastolic blood pressure (0.11 mm Hg; 95% CI: -0.04 to 0.27 mm Hg) between the active and placebo treatment groups. This null result was robust in analyses accounting for nonadherence to study pills and in baseline subgroups of interest, including black subjects and women with hypertension or high levels of blood pressure, with low intakes of calcium and vitamin D or low serum levels of vitamin D. In 17 122 nonhypertensive participants at baseline, the hazard ratio for incident hypertension associated with calcium/vitamin D treatment was 1.01 (95% CI: 0.96 to 1.06.) In postmenopausal women, calcium plus vitamin D3 supplementation did not reduce either blood pressure or the risk of developing hypertension over 7 years of follow-up.

Evidence linking sex hormone concentrations with risk for recurrence in women diagnosed with breast cancer is limited; however, beneficial effects of antiestrogenic therapy on recurrence-free survival suggest that these hormones affect progression and risk for recurrence. This study examined whether baseline serum concentrations of estradiol, testosterone, and sex hormone binding globulin were associated with recurrence-free survival in a nested case-control cohort of women from a randomized diet trial (Women's Healthy Eating and Living Study) who were followed for >7 years after diagnosis. In 153 case-control pairs of perimenopausal and postmenopausal women in this analysis, total estradiol [hazard ratio (HR), 1.41 per unit increase in log concentration; 95% confidence interval (95% CI), 1.01-1.97], bioavailable estradiol (HR, 1.26; 95% CI, 1.03-1.53), and free estradiol (HR, 1.31; 95% CI, 1.03-1.65) concentrations were significantly associated with risk for recurrence. Recurred women had an average total estradiol concentration that was double that of nonrecurred women (22.7 versus 10.8 pg/mL; P = 0.05). Testosterone and sex hormone binding globulin concentrations did not differ between cases and controls and were not associated with risk for recurrence. Although genetic and metabolic factors likely modulate the relationship between circulating sex hormones and risk, results from this study provide evidence that higher serum estrogen concentration contributes to risk for recurrence in women diagnosed with early stage breast cancer.

Psychosocial and behavioral profile and predictors of self-reported energy underreporting in obese middle-aged women.. Journal of the American Dietetic Association, 108(1), 114-9. doi:10.1016/j.jada.2007.10.007More infoEnergy underreporting is a concern with dietary intake data; therefore, subject characteristics associated with underreporting energy intake should be elucidated. Baseline self-reported dietary intake and measures of diet and weight history, life status, weight-loss readiness, psychology, eating behavior, physical activity, and self-image of obese middle-aged women (mean body mass index [calculated as kg/m(2)]=31.0) enrolled in a lifestyle weight-loss program were evaluated. Of the 155 participating, 71 women were identified as underreporting energy intake using the Goldberg cutoff values. Comparison of means between psychosocial and behavioral measures from energy underreporters and energy accurate reporters were used to help develop logistic regression models that could predict likelihood to underreport energy intake based on baseline measures. Characteristics most predictive of energy underreporting included fewer years of education (P=0.01), less-realistic weight-loss goals (P=0.02), higher perceived exercise competence (P=0.07), more social support to exercise (P=0.04), more body-shape concern (P=0.01), and higher perception of physical condition (P=0.03). These results highlight distinct psychosocial and behavioral characteristics that, at baseline, can help identify the likelihood an overweight middle-aged woman entering a weight-loss intervention will underreport energy intake. These results can help provide a framework for screening study participants for probability of energy underreporting, based on baseline psychosocial and behavioral measures. This knowledge can help researchers target at-risk subjects and, through education and training, improve the accuracy of self-reported energy intake and, ultimately, the accuracy of energy and nutrient intake relationships with health and disease.

Fat samples were subjected to saponification followed by solvent extraction. d-Limonene in the sample extract was analyzed using gas chromatography-mass spectrometry (GC-MS) with selected ion monitoring. Linear calibration curves were established over the mass range of 79.0-2529 ng d-limonene per 0.1g of adipose tissue. Satisfactory within-day precision (R.S.D. 6.7-9.6%) and accuracy (%difference of -2.7 to 3.8%) and between-day precision (R.S.D. 6.0-10.7%) and accuracy (%difference of 1.8-2.6%) were achieved. The assay was successfully applied to human fat biopsy samples from a d-limonene feeding trial.

Abstract B125: Adipose tissue accumulation of d-limonene with the consumption of a lemonade preparation rich in d-limonene content.. Cancer Prevention Research, 1. doi:10.1158/1940-6207.prev-08-b125More infoB125 Purpose d-Limonene is a bioactive food component commonly found in high concentration in citrus peel. It has demonstrated anti-cancer effects in preclinical studies with the most compelling results in mammary carcinogenesis models. Information on the oral bioavailability and tissue disposition of d-limonene in humans is rather limited for extrapolation of preclinical data to human situations. As a fat-soluble compound, d-limonene is more likely to deposit in fatty tissues such as the breast where we hypothesize that biologic activity may be greatest. We conducted a clinical study to determine the systemic and adipose tissue disposition of d-limonene with the consumption of a lemonade preparation rich in d-limonene content. Methods Seven healthy adults underwent a one-week washout period during which their diets were void of all citrus. At entry, participants consumed a breakfast that included the freshly prepared lemonade (40 oz containing 0.6 gm d-limonene) in the clinic. Serum and needle fat biopsies of the buttocks were collected 6 hours post-feeding. Participants then consumed 40 oz of freshly prepared lemonade daily for 4 weeks. At completion of the 4-week feeding period, participants repeated the controlled breakfast with high d-limonene lemonade prepared in the clinic followed by repeat serum and fat sampling. Matched pre- and post-intervention fat biopsies (n = 7) and serum samples (n = 6) were analyzed for d-limonene levels using gas chromatography-mass spectrometry. Results The d-limonene levels in the initial fat biopsies ranged from non-detectable to 0.79 μM (median = 2.55 μM) concentration. The adipose d-limonene levels increased significantly (p Conclusions Oral consumption of high d-limonene lemonade results in d-limonene deposition in adipose tissue in levels much higher than levels in the systemic circulation. Assessing the serum d-limonene levels is not likely to reflect d-limonene exposure in the adipose tissue. In addition, given d-limonene’s anticarcinogenic properties, and because breast tissue is mostly composed of adipose, the data suggests that d-limonene could also accumulate at this site, thus potentially modulating breast cancer risk.

Postmenopausal status was defined as an absence of any menstrual cycle within the past 12 calendar months or having a follicle-stimulating hormone level between 22 and 138 mIU/mL. The participants' most recent mammograms were used for the mammographic density analysis. Body composition was measured by dual-energy x-ray absorptiometry. The associations between the percentage of mammographic density or mammographic dense area and body composition components were analyzed using logistic regression..Mammographic dense areas were similar in Hispanic and non-Hispanic white women. The percentage of mammographic density varied by ethnicity in premenopausal (P = 0.023), but not in postmenopausal women. Body composition, both higher lean mass and lower fat mass, was associated with a higher percentage of mammographic density (P < 0.05). Interestingly, a higher percentage of total body fat mass and a lower percentage of total body lean mass were correlated with larger breast dense areas in premenopausal women but with lower breast dense areas in postmenopausal women. These relationships between body composition and mammographic density measurements were not significantly affected by factors such as age, ethnicity, and body weight..Body composition is highly correlated with mammographic density and should be examined as a possible confounding factor in studies involving mammographic density measurements and breast cancer risk.

Nutrition and cancer, 60(6), 710-9. doi:10.1080/01635580802233983More infoAntioxidant nutrients and carotenoids have been inconsistently associated with ovarian cancer risk. We examined the relationship between intake of dietary and supplemental antioxidant nutrients including vitamins C, E, and selenium as well as carotenoids and vitamin A and ovarian cancer in 133,614 postmenopausal women enrolled in the Women's Health Initiative (WHI) study. Dietary intake was assessed using a food frequency questionnaire, and ovarian cancer endpoints were centrally adjudicated. Cox regression models were used to estimate the risk for invasive ovarian cancer in relation to each of the antioxidant nutrients and carotenoids under consideration using models stratified for a WHI study component. A total of 451 cases of invasive ovarian cancer were diagnosed over 8.3 yr of follow-up. Dietary intake at baseline was not significantly different for cases vs. controls. Cases reported greater intake of supplemental vitamin C (358.0 mg/day vs. 291.6 mg/day, respectively; P = 0.024). Multivariate modeling (P for trend) of the risk for developing ovarian cancer did not suggest any significant relationships among dietary factors and ovarian cancer risk. The results from this prospective study of well-nourished, postmenopausal women suggest that intake of dietary antioxidants, carotenoids, and vitamin A are not associated with a reduction in ovarian cancer risk.

Use of recovery biomarkers to calibrate nutrient consumption self-reports in the Women's Health Initiative.. American journal of epidemiology, 167(10), 1247-59. doi:10.1093/aje/kwn026More infoUnderreporting of energy consumption by self-report is well-recognized, but previous studies using recovery biomarkers have not been sufficiently large to establish whether participant characteristics predict misreporting. In 2004-2005, 544 participants in the Women's Health Initiative Dietary Modification Trial completed a doubly labeled water protocol (energy biomarker), 24-hour urine collection (protein biomarker), and self-reports of diet (assessed by food frequency questionnaire (FFQ)), exercise, and lifestyle habits; 111 women repeated all procedures after 6 months. Using linear regression, the authors estimated associations of participant characteristics with misreporting, defined as the extent to which the log ratio (self-reported FFQ/nutritional biomarker) was less than zero. Intervention women in the trial underreported energy intake by 32% (vs. 27% in the comparison arm) and protein intake by 15% (vs. 10%). Younger women had more underreporting of energy (p = 0.02) and protein (p = 0.001), while increasing body mass index predicted increased underreporting of energy and overreporting of percentage of energy derived from protein (p = 0.001 and p = 0.004, respectively). Blacks and Hispanics underreported more than did Caucasians. Correlations of initial measures with repeat measures (n = 111) were 0.72, 0.70, 0.46, and 0.64 for biomarker energy, FFQ energy, biomarker protein, and FFQ protein, respectively. Recovery biomarker data were used in regression equations to calibrate self-reports; the potential application of these equations to disease risk modeling is presented. The authors confirm the existence of systematic bias in dietary self-reports and provide methods of correcting for measurement error.

Nutrition and cancer, 57(1), 11-9. doi:10.1080/01635580701267875More infoConsumption of cruciferous vegetables has been associated with reduced breast cancer risk mechanistically and in population-based studies, although evidence has been inconsistent. This inconsistency may be related to limitations in quantifying and qualifying cruciferous vegetable exposure using standard instruments for dietary assessment (for example, food-frequency questionnaires, FFQs) or due to low levels of intake demonstrated among U.S. population samples. Cruciferous vegetable intake data are presented from a longitudinal study of a high-vegetable dietary intervention to reduce breast cancer recurrence among breast cancer survivors (n=1,156; 536 intervention and 620 comparison group subjects). Intake was assessed using repeat administration of an FFQ and cross-sectional administration of a cruciferous vegetable-specific FFQ (CVFFQ). Mean intake in the intervention group assessed using the standard FFQ was 37.7 g/day at baseline and increased to 57.1 g/day at 12 mo (P=0.0001) and was sustained through 48 mo. Broccoli and cabbage were the most commonly consumed cruciferous vegetables, regardless of the instrument used to assess intake. Differences in intake by group assignment were shown for raw cruciferous vegetables (30.2 g/day vs. 24.6 g/day, assessed using the CVFFQ), suggesting increased exposure to biologically active, cancer-preventive food constituents. These data suggest that this study population will be the first U.S. population sample to provide ample quantity and variety in cruciferous intake to examine whether these vegetables are protective against breast cancer recurrence.

Effect of body composition change on markers of metabolic syndrome in breast cancer survivors on either fat or carbohydrate restricted diets.. Cancer Epidemiology and Prevention Biomarkers, 16.More infoA21 Women previously treated for breast cancer are at risk for post-treatment morbidity including obesity, cardiovascular disease, diabetes, and sarcopenia or sarcopenic obesity. The encouragement of weight loss for the management of comorbidities and metabolic disturbance, without consideration of protein content or physical activity, may exacerbate sarcopenia, compromise functional status and lead to increasing risk of future fractures. The purpose of this study is to evaluate the relationship between changes in body composition and metabolic status in the survivor population. >In an ongoing, randomized, weight loss intervention of low fat or low carbohydrate diets in breast cancer survivors (N=37; Age 55.4 ± 9.7 yrs; BMI >25 kg/m2) on adjuvant hormonal therapies, standard anthropometry (height, weight, waist, and hip circumferences) and total and region body fat, lean, and bone mass measures were performed (dual X-ray absorptiometry). Total cholesterol, triglycerides (TG), high density lipoprotein cholesterol (HDL), insulin, glycosylated hemoglobin, and glucose were also measured by the clinical diagnostic laboratory. >At baseline, we found that 32% of participants had elevated (>3.5) TG/HDL values, a sensitive and specific surrogate measure for insulin resistant, dyslipidemic individuals. In intervention completers thus far (N=14), using the new ATP III criterion, cases of metabolic syndrome were cut by 56% following intervention (metabolic syndrome by ATP III 64% at baseline, 29% at 24weeks) in this survivor group. >At 24 weeks, completers also demonstrated significant improvements in weight and body fat, with suggested loss in lean mass. Although measures of glucose were not altered, fasting insulin and glycosylated hemoglobin were significantly reduced, consistent with improved insulin sensitivity. >Investigations of high protein diets in cancer survivors for the preservation of lean mass during weight loss are limited.

The purpose of this study was to examine factors that are associated with physical activity or inactivity among breast cancer survivors..Data from 3088 women participating in the Women's Healthy Eating and Living (WHEL) Study, collected prior to randomization, were the focus of the current analyses. Self-reports of physical activity levels, quality of life, depression, and dietary intakes were collected. Pearson correlation analyses were employed to examine the associations among these variables, and multiple regression analyses were performed to examine the relationship between selected health behaviors and physical activity levels, after controlling for demographic, breast cancer-related, and psychosocial variables..Demographic and psychosocial variables were related to physical activity levels (P < 0.001 for all). Cancer treatment type and cancer stage were correlated with survivors' physical activity levels (P < 0.01), but the associations were no longer significant after controlling for demographic variables. Physical activity levels were strongly associated with other health behaviors, especially dietary intakes (P < 0.001), even after controlling for demographic, cancer-related, and psychosocial factors..Low physical activity levels in breast cancer survivors are associated with specific behavioral and other factors, which can be considered as indicators of women at higher risk. Findings of significant differences in physical activity levels based on demographic characteristics suggest the importance of promoting physical activity particularly among breast cancer survivors of ethnic minority or lower education levels.

The Journal of nutrition, 137(10), 2291-6. doi:10.1093/jn/137.10.2291More infoAchieving long-term adherence to a dietary pattern is a challenge in many studies investigating the relationship between diet and disease. The Women's Healthy Eating and Living Study was a multi-institutional randomized trial in 3088 women at risk for breast cancer recurrence. At baseline, the average participant followed a healthy dietary pattern of 7 vegetable and fruit servings, 21 g/d of fiber, and 28.7% energy from fat, although fat intake increased over the enrollment period. Using primarily telephone counseling, the intervention group was encouraged to substantially increase intakes of vegetables, fruits, and fiber while decreasing fat intake. Sets of 24-h dietary recalls were completed on 90% of eligible participants at 1 y and 86% at 4 y. Using a conservative imputation analysis, at 1 y, the intervention group consumed 38% more vegetable servings (100% when including juice) than the comparison group, 20% more fruit, 38% more fiber, 50% more legumes, and 30% more whole grain foods, with a 20% lower intake of energy from fat. At 4 y, the between-group differences were 65% for vegetables (including juice), 25% fruit, 30% fiber, 40% legumes, 30% whole grain foods, and 13% lower intake of energy from fat. The intervention effect on fat intake was similar for early vs. late enrollees. Plasma carotenoid concentrations on a random 28% sample validated self-reported vegetable and fruit intake, with a between-group difference of 66% at 1 y and over 40% at 4 y. This large change will allow testing of hypotheses on the role of dietary change in preventing additional breast cancer events.

The comparison group (n = 1551) was provided with print materials describing the "5-A-Day" dietary guidelines..Invasive breast cancer event (recurrence or new primary) or death from any cause..From comparable dietary patterns at baseline, a conservative imputation analysis showed that the intervention group achieved and maintained the following statistically significant differences vs the comparison group through 4 years: servings of vegetables, +65%; fruit, +25%; fiber, +30%, and energy intake from fat, -13%. Plasma carotenoid concentrations validated changes in fruit and vegetable intake. Throughout the study, women in both groups received similar clinical care. Over the mean 7.3-year follow-up, 256 women in the intervention group (16.7%) vs 262 in the comparison group (16.9%) experienced an invasive breast cancer event (adjusted hazard ratio, 0.96; 95% confidence interval, 0.80-1.14; P = .63), and 155 intervention group women (10.1%) vs 160 comparison group women (10.3%) died (adjusted hazard ratio, 0.91; 95% confidence interval, 0.72-1.15; P = .43). No significant interactions were observed between diet group and baseline demographics, characteristics of the original tumor, baseline dietary pattern, or breast cancer treatment..Among survivors of early stage breast cancer, adoption of a diet that was very high in vegetables, fruit, and fiber and low in fat did not reduce additional breast cancer events or mortality during a 7.3-year follow-up period..clinicaltrials.gov Identifier: NCT00003787.

Cancer stage and treatment modalities were obtained by medical record review; demographic and physical activity data were obtained from questionnaires. Weight gain of >/=5% body weight following cancer diagnosis was considered significant..Chemotherapy was significantly associated with weight gain (OR = 1.65, 95% CI = 1.12, 2.43) and Tamoxifen((R)) was not (OR = 1.03, 95% CI = 0.71, 1.51). Tamoxifen((R)) did not modify the effect of either chemotherapy or its different regimens on weight gain. Both types (anthracycline: OR = 1.63, p-value = 0.01, non-anthracycline: OR = 1.79, p = 0.003) and all regimens of chemotherapy (AC: OR = 1.55, p-value = 0.01, CAF: OR = 1.83, p = 0.003, CMF: OR = 1.76, p = 0.004) were associated with weight gain but the associations were not different from one another.

Archives of internal medicine, 167(17), 1837-44. doi:10.1001/archinte.167.17.1837More infoThe immune system and inflammation are implicated in the pathogenesis of cancer. Prospective studies linking biomarkers of inflammation with cancer incidence and mortality have been inconclusive..To determine whether there is an independent association of white blood cell (WBC) count with incident cancer in postmenopausal women, a prospective cohort study was performed at 40 US clinical centers involving 143,748 postmenopausal women aged 50 to 79 years who were free of cancer at baseline and were enrolled in the Women's Health Initiative. The main outcome measures were incident invasive breast, colorectal, endometrial, and lung cancer..In multivariate models, there was a graded association of WBC count with incidence of all 4 types of cancer. Compared with the lowest quartile of WBC count (2.50-4.79x10(9) cells/L), women with a WBC count in the upper quartile (6.80-15.00x10(9) cells/L) had a statistically significantly higher risk of invasive breast cancer (hazard ratio [HR], 1.15; 95% confidence interval [CI], 1.04-1.26), colorectal cancer (HR, 1.19; 95% CI, 1.00-1.41), endometrial cancer (HR, 1.42; 95% CI, 1.12-1.79), and lung cancer (HR, 1.63; 95% CI, 1.35-1.97). The findings were similar when cancers that occurred during the first 2 years of follow-up were excluded. Statistically significant associations remained for invasive breast cancer and endometrial cancer when the analyses were limited to nonsmokers. The WBC count was also statistically significantly associated with breast cancer, lung cancer, and overall cancer mortality..Postmenopausal women with higher WBC counts have a higher risk of incident invasive breast, colorectal, endometrial, and lung cancer, as well as a higher risk of breast, lung, and overall cancer mortality.

Studies examining the role of carotenoid consumption in relation to breast cancer recurrence are limited and report mixed results. We tested the hypothesis that breast cancer survivors with high dietary and plasma carotenoids would show significantly lower levels of oxidative stress than breast cancer survivors with low dietary and plasma carotenoid levels. Two hundred seven postmenopausal breast cancer survivors from the Women's Healthy Eating and Living Study volunteered for this ancillary study. Dietary data were analyzed by the Arizona Food Frequency Questionnaire and plasma carotenoids alpha-carotene, beta-carotene, lutein plus zeaxanthin, lycopene, and beta-cryptoxanthin and quantified with high-performance liquid chromatography, and immunoaffinity chromatography-monoclonal antibody-based ELISAs were used to analyze the urine samples for 8-hydroxy-2'-deoxyguanosine (8-OhdG) and 8-iso-prostaglandin-F2alpha (8-iso-PGF2alpha). The correlations between dietary and plasma carotenoids were 0.34 for beta-carotene, 0.46 for alpha-carotene, 0.39 for beta-cryptoxanthin, 0.27 for lycopene, 0.30 for lutein plus zeaxanthin, and 0.30 for total carotenoids. The 8-OHdG oxidative stress biomarker was significantly reduced at the highest quartile of total plasma carotenoid concentrations (P = 0.001) and 8-iso-PGF2alpha was moderately reduced (P = 0.088). Dietary carotenoid levels were not significantly associated with oxidative, stress indicators, although dietary lycopene and lutein/zeaxanthin were modestly associated with 8-OHdG levels (P = 0.054 and 0.088, respectively). Key findings include a significant inverse association between total plasma carotenoid concentrations and oxidative stress as measured by urinary 8-OHdG and a moderately significant inverse association with 8-iso-PGF2alpha, a protective association that was not shown for dietary carotenoid intake.

Journal of women's health (2002), 16(3), 379-89. doi:10.1089/jwh.2006.m078More infoDiet quality and risks of chronic disease have been identified, yet nutrient intakes from older uninsured populations have been scarcely described..Using the dietary intake profiles of an older, uninsured, and mostly Hispanic sample of Arizona WISEWOMAN participants, two ethnic groups were compared: Mexican American and non-Hispanic white women. Sociodemographic data related to nutrient intakes were identified. Estimated mean nutrient intakes of Mexican Americans (n = 260) and non-Hispanic white (n = 88) women were compared based on ethnicity and acculturation levels. Using linear regression models, associations of individual characteristics were made on nutrients for which reported intakes were less than the estimated average requirement (EAR)..Mexican Americans had energy, vitamin E, and niacin intakes that were significantly lower than those of non-Hispanic whites, whereas vitamin A intake was significantly higher among Mexican Americans. Less acculturated Mexican American women had significantly higher intakes of vitamin E and folate than their more acculturated counterparts. For both ethnic and acculturation groups, intakes of vitamin E, calcium, and potassium were lower than the established standards in more than 70% of this population. Having a high body mass index (BMI) was associated with lower reported energy intake and higher protein and potassium intakes, and smoking was associated with lower intakes of vitamin E and folate..Mexican American women had overall lower micronutrient intakes compared with uninsured non-Hispanic white older women; this difference may be attributed to their underreporting intake.

Few studies have examined the influence of one-carbon nutrients on pancreatic cancer risk, although recent studies suggest a potential protective effect for one-carbon nutrients from food sources, but not from supplements. We conducted a prospective nested case-control study to examine plasma concentrations of folate, vitamin B6 [whose main circulating form is pyridoxal-5'-phosphate (PLP)], vitamin B12, and homocysteine in relationship to pancreatic cancer, using four large prospective cohorts. Multivariable adjusted odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using conditional logistic regression. All statistical tests were two sided. Among 208 cases and 623 controls, we observed no association between folate, PLP, vitamin B12, or homocysteine and pancreatic cancer risk. Comparing the highest to lowest quartiles of plasma concentration, the ORs were 1.20 (95% CI, 0.76-1.91) for folate, 0.80 (95% CI, 0.51-1.25) for B6, 0.91 (95% CI, 0.57-1.46) for B12, and 1.43 (95% CI, 0.90-2.28) for homocysteine. In analyses restricted to nonusers of multivitamins, we observe a modest inverse trend between folate, PLP, and B12 and pancreatic cancer risk. In contrast, no such inverse associations were observed among study subjects who reported multivitamin supplement use. Among all participants, plasma levels of folate, B6, B12, and homocysteine were not associated with a significant reduction in the risk of pancreatic cancer. Among participants who obtain these factors exclusively through dietary sources, there may be an inverse relation between circulating folate, B6, and B12 and risk.

The purpose of this study was to provide pilot data describing the relationship between dietary variables and mammographic density in pre- and postmenopausal Hispanic and non-Hispanic white (NHW) women (N=238) ranging in age from 41 to 50 years (premenopausal only) or 56 to 70 years (postmenopausal only)..Using a cross-sectional design, computer-assisted density assessments were performed on mammograms of both breasts and averaged for analysis. The Arizona Food Frequency Questionnaire was used to estimate dietary intake..Study participants were well educated and overweight, with mean mammographic densities ranging from 20.25% for postmenopausal Hispanic women to 46.94% for premenopausal NHW women. Hispanic women reported higher energy intake than NHW women, but energy-adjusted intake of other nutrients was generally comparable. There was preliminary evidence of ethnic variability in diet-mammographic density associations. Among premenopausal Hispanic women, density was inversely associated with dairy, calcium, and vitamin D intakes (P

Journal of the National Cancer Institute, 99(20), 1534-43. doi:10.1093/jnci/djm159More infoThe Women's Health Initiative Dietary Modification (DM) Randomized Controlled Trial evaluated the effects of a low-fat dietary pattern on chronic disease incidence, with breast cancer and colorectal cancer as primary outcomes. The trial protocol also listed ovarian cancer and endometrial cancer as outcomes that may be favorably affected by the intervention..A total of 48,835 postmenopausal women were randomly assigned during 1993-1998 to a DM intervention (n = 19,541) or comparison (usual diet; n = 29,294) group and followed up for an average of 8.1 years. The intervention goal was to reduce total fat intake to 20% of energy and to increase consumption of vegetables, fruits, and grains. Cancer outcomes were verified by pathology report review. We used weighted log-rank tests to compare incidence of invasive cancers of the ovary and endometrium, total invasive cancer, and invasive cancers at other sites between the groups. All statistical tests were two-sided..Ovarian cancer risk was lower in the intervention than in the comparison group (P = .03). Although the overall ovarian cancer hazard ratio (HR) was not statistically significantly less than 1.0, the hazard ratio decreased with increasing intervention duration (P(trend) = .01). For the first 4 years, the risk for ovarian cancer was similar in the intervention and control groups (0.52 cases per 1000 person-years in the intervention group versus 0.45 per 1000 person-years in the comparison group; HR = 1.16, 95% confidence interval [CI] = 0.73 to 1.84); over the next 4.1 years, the risk was lower in the intervention group (0.38 cases per 1000 person-years in the intervention group versus 0.64 per 1000 person-years in the comparison group; HR = 0.60, 95% CI = 0.38 to 0.96). Risk of cancer of the endometrium did not differ between the groups (P = .18). The estimated risk of total invasive cancer was slightly lower in the intervention group than in the control group (HR = 0.95, 95% CI = 0.89 to 1.01; P = .10)..A low-fat dietary pattern may reduce the incidence of ovarian cancer among postmenopausal women.

Controlled environments for production of value-added food crops with high phytochemical concentrations : Lycopene in tomato as an example. Hortscience, 41(3), 522-525. doi:10.21273/hortsci.41.3.522More infoSummary. Plants produce various phytochemicals that are of nutritional and medicinal value to humans. Phytochemicals having antioxidant capacity are drawing increased interest from consumers. Population studies among Americans have consistently demonstrated inadequate consumption of fruit and vegetables. Improving intake of fruit and vegetables has been a major public health effort for many years with minimal success. Given this, it seems opportunistic to consider other approaches to enhance the nutritional quality of the American diet. One plausible approach is the development of fresh produce containing a greater concentration of phytochemicals known to improve health, thus while consuming fewer servings of produce, Americans would still have significant exposure to health-promoting food constituents. Controlled environments provide a unique opportunity to modify the concentrations of selected phytochemicals in fruit and vegetables, yet practical information is limited regarding methods effective in optimizing antioxidant capacity. Our research at the University of Arizona Controlled Environment Agriculture Program has shown that application of moderate salt stress to tomato plants can enhance lycopene and potentially other antioxidant concentrations in fruit. The increase in lycopene in response to salt stress in the tomato fruit was shown to be cultivar specific, varying from 34% to 85%. Although the specific biological mechanisms involved in increasing fruit lycopene deposition has not been clearly elucidated, evidence suggests that increasing antioxidant concentrations is a primary physiological response of the plant to the salt stress. Another experiment showed that low temperature during postharvest increased antioxidant capacity of tomato fruit while it maintained the lycopene concentration. More detailed study in this area is needed including accumulation of antioxidant phytochemicals as affected by environmental conditions during the cultivation and the postharvest. of greenhouse tomato available in U.S. retail markets has increased dramatically during the past decade and now accounts for 37% of the weekly quantity of tomatoes sold in the average U.S. supermarket in 2003 (Cook and Calvin, 2005), where this quantity included produce imported from Mexico and Canada. This suggests that greenhouse tomatoes are preferred in retail sales likely due to the consistent supply and generally higher quality than field grown tomatoes. This trend seems driving neighboring countries more into greenhouse production.

Nutrition reviews, 64(2 Pt 1), 53-66. doi:10.1301/nr.2006.feb.53-66More infoEnergy underreporting occurs in 2% to 85% and overreporting in 1% to 39% of various populations. Efforts are needed to understand the psychosocial and behavioral characteristics associated with misreporting to help improve the accuracy of dietary self-reporting. Past research suggests that higher social desirability and greater eating restraint are key factors influencing misreporting, while a history of dieting and being overweight are more moderately associated. Eating disinhibition, body image, depression, anxiety, and fear of negative evaluation may be related to energy misreporting, but evidence is insufficient. This review will provide a detailed discussion of the published associations among psychosocial and behavioral characteristics and energy misreporting.

American journal of epidemiology, 163(8), 770-8. doi:10.1093/aje/kwj082More infoVegetables and fruits are rich in carotenoids, a group of compounds thought to protect against cancer. Studies of diet-disease associations need valid and reliable instruments for measuring dietary intake. The authors present a measurement error model to estimate the validity (defined as correlation between self-reported intake and "true" intake), systematic error, and reliability of two self-report dietary assessment methods. Carotenoid exposure is measured by repeated 24-hour recalls, a food frequency questionnaire (FFQ), and a plasma marker. The model is applied to 1,013 participants assigned between 1995 and 2000 to the nonintervention arm of the Women's Healthy Eating and Living Study, a randomized trial assessing the impact of a low-fat, high-vegetable/fruit/fiber diet on preventing new breast cancer events. Diagnostics including graphs are used to assess the goodness of fit. The validity of the instruments was 0.44 for the 24-hour recalls and 0.39 for the FFQ. Systematic error accounted for over 22% and 50% of measurement error variance for the 24-hour recalls and FFQ, respectively. The use of either self-report method alone in diet-disease studies could lead to substantial bias and error. Multiple methods of dietary assessment may provide more accurate estimates of true dietary intake.

Other intervention studies have not achieved the level of change in circulating carotenoids required to properly test this hypothesis..In a randomized trial of 2,922 breast cancer survivors, we examined blood and self-reported diet at baseline and 1 year. Intensive telephone counseling encouraged a plant-based diet in the intervention group. Diet was measured via 24-hour recalls, and a panel of plasma carotenoid concentrations was assessed at both time points..The study intervention was associated with a 51% increase in total carotenoid concentration, from 2.272 +/- 1.294 to 3.440 +/- 2.320 micromol/L, achieved mainly by marked increases in targeted carotenoids: alpha-carotene, beta-carotene, and lutein. For each of these targeted carotenoids, the proportion of the intervention sample remaining below the cutpoint for the lowest baseline quartile decreased by one third to one half. After 1 year of study, half of the intervention group was in the highest baseline quartile. No change in distribution was observed in comparison group. Intervention participants achieved this change by both dietary pattern and vegetable juice consumption. Participants who chose to change dietary pattern without consuming significant quantities of vegetable juice achieved 75% of the level of change observed in other intervention participants..Innovative telephone counseling intervention and dietary targets in the Women's Healthy Eating and Living study were associated with the level of change in circulating carotenoid concentration necessary to test the diet and breast cancer hypothesis suggested by cohort studies.

We computed weight change from 1 year prior to diagnosis to study enrollment. Delayed entry Cox proportional hazards models were used to evaluate associations of categories of weight change with time to recurrence, controlling for known prognostic factors..Neither moderate (5-10%) nor large (> 10%) weight gain (HR 0.8, 95% CI, 0.6-1.1; HR 0.9, 95% CI, 0.7-1.2, respectively) after breast cancer diagnosis was associated with an increased risk of breast cancer recurrence in the early years post-diagnosis (median time of 73.7 months from diagnosis)..Our research provides evidence that weight gain commonly seen in the first several years following a breast cancer diagnosis does not increase a woman's risk for breast cancer recurrence in the first 5-7 years post-diagnosis. However, this research does not address the effects of weight gain on overall survival or on the risk of other new cancers, other prognostic outcomes of concern to the breast cancer survivor.

It is well established that Hsp70 and Hsp70 antibodies are present in human serum. This study reports on the development of an ELISA assay for the Hsp70 co-chaperone, HspBP1. HspBP1 is present in human serum at concentrations ranging between 0.74 to 3.98 ng/mL. No gender or age differences in the HspBP1 levels were identified. It was also found that human serum contained antibodies to HspBP1, and there were no gender or age differences in these levels. In addition, there was no correlation between the level of HspBP1 in a sample and the antibody titer. Finally, we found that HspBP1 in serum is complexed to anti-HspBP1 antibodies.

Development of a glycemic index database for food frequency questionnaires used in epidemiologic studies.. The Journal of nutrition, 136(6), 1604-9. doi:10.1093/jn/136.6.1604More infoConsumption of foods with a high glycemic index (GI) or glycemic load (GL) is hypothesized to contribute to insulin resistance, which is associated with increased risk of diabetes mellitus, obesity, cardiovascular disease, and some cancers. However, dietary assessment of GI and GL is difficult because values are not included in standard food composition databases. Our objective was to develop a database of GI and GL values that could be integrated into an existing dietary database used for the analysis of FFQ. Food GI values were obtained from published human experimental studies or imputed from foods with a similar carbohydrate and fiber content. We then applied the values to the Women's Health Initiative (WHI) FFQ database and tested the output in a random sample of previously completed WHI FFQs. Of the 122 FFQ line items (disaggregated into 350 foods), 83% had sufficient carbohydrate (>5 g/serving) for receipt of GI and GL values. The foods on the FFQ food list with the highest GL were fried breads, potatoes, pastries, pasta, and soft drinks. The fiber content of foods had very little influence on calculated GI or GL estimates. The augmentation of this FFQ database with GI and GL values will enable etiologic investigations of GI and GL with numerous disease outcomes in the WHI and other epidemiologic studies that utilize this FFQ.

There is debate about optimum calorie balance for prevention of weight gain, and proponents of some low-carbohydrate diet regimens have suggested that the increasing obesity may be attributed, in part, to low-fat, high-carbohydrate diets..To report data on body weight in a long-term, low-fat diet trial for which the primary end points were breast and colorectal cancer and to examine the relationships between weight changes and changes in dietary components..Randomized intervention trial of 48,835 postmenopausal women in the United States who were of diverse backgrounds and ethnicities and participated in the Women's Health Initiative Dietary Modification Trial; 40% (19,541) were randomized to the intervention and 60% (29,294) to a control group. Study enrollment was between 1993 and 1998, and this analysis includes a mean follow-up of 7.5 years (through August 31, 2004)..The intervention included group and individual sessions to promote a decrease in fat intake and increases in vegetable, fruit, and grain consumption and did not include weight loss or caloric restriction goals.

Fruit and vegetable consumption of older Mexican-American women is associated with their acculturation level.. Ethnicity & disease, 16(1), 89-95.More infoLittle is known about the association between acculturation and fruit and vegetable (FV) consumption among older Mexican-American (MA) women. Environmental and lifestyles changes experienced by immigrants to the United States may markedly affect their diet and health and increase their risk for chronic diseases. Our objectives were to: 1) describe FV consumption by ethnicity, acculturation, and sociodemographic characteristics, and 2) compare effects of acculturation and sociodemographic variables on FV intake in a population of older MA and non-Hispanic White (NHW) women from the Well-Integrat-ed Screening and Evaluation for Women Across the Nation (WISEWOMAN) Study. This report examines baseline FV intake of 346 underinsured women aged 50-76 years, assessed through 24-hour dietary recalls. Acculturation was measured with a five-item Likert-type scale. Twenty percent of more acculturated MA women, 24% of less acculturated MA women, and 36% of White women consumed > or = 5 servings of FV servings per day. Fruit and vegetable (FV) intake was associated with acculturation, education, and smoking status. Being more acculturated was associated with lower consumption of FVs among MAs, while having a higher education and no smoking was associated with higher intakes of FV servings among NHWs. Public health efforts to improve the intake of FVs among MA women should be sensitive to their acculturation status.

Plasma folate, vitamins B6, B12, and homocysteine and pancreatic cancer risk in four large cohorts.. Cancer Epidemiology and Prevention Biomarkers, 15.More infoFifth AACR International Conference on Frontiers in Cancer Prevention Research, Nov 12-15, 2006 A9 Background. Folate deficiency induces DNA breaks and may elevate the risk of pancreatic cancer through altered cellularcapacity for mutation and epigenetic methylation. Few studies have examined the influence of one-carbon nutrients on pancreatic cancer risk, although recent studies suggest a potential protective effect for one-carbon nutrients from food sources, but not from supplements. Methods. We conducted a prospective nested case-control study to examine plasma concentrations of folate, vitamin B6, whose main circulating form is pyridoxal-5'-phosphate (PLP), vitamin B12, and homocysteine in relationship to pancreatic cancer. In this largest study to date, we combined four prospective cohort studies of women and men, participating in the Nurses' Health Study (NHS), the Health Professionals Follow-up Study (HPFS), Physicians' Health Study (PHS), and Women's Health Initiative (WHI). Multivariable adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression. Primary analyses excluded cases that occurred in the first two years after blood collection, leaving a total of 208 cases and 623 controls. All statistical tests were two-sided. Results. Overall, we observed no association between plasma concentrations of folate, PLP, vitamin B12, or homocysteine and the subsequent risk of pancreatic cancer. Comparing the highest to lowest quartiles of plasma concentration, the ORs were 1.20 (95% Confidence Interval (CI), 0.76-1.91) for folate, 0.80 (95% CI, 0.51-1.25) for B6, 0.91 (95% CI, 0.57-1.46) for B12, and 1.43 (95% CI, 0.90-2.28) for homocysteine. In analyses restricted to nonusers of multivitamins, we observe a modest inverse trend between folate, PLP, and B12 and pancreatic cancer risk, which reached statistical significance for PLP(OR, 0.47, 95% CI, 0.24-0.92). In contrast, no such inverse associations were observed among study subjects who reported multivitamin supplement use. Conclusion. Among all participants, plasma levels of folate, B6, B12, and homocysteine were not associated with a significant reduction in the risk of pancreatic cancer. Among participants who obtain these factors exclusively through dietary sources, there may be an inverse relation between circulating folate, B6, and B12 and risk.

JAMA, 295(6), 629-42. doi:10.1001/jama.295.6.629More infoThe hypothesis that a low-fat dietary pattern can reduce breast cancer risk has existed for decades but has never been tested in a controlled intervention trial..To assess the effects of undertaking a low-fat dietary pattern on breast cancer incidence..A randomized, controlled, primary prevention trial conducted at 40 US clinical centers from 1993 to 2005..A total of 48,835 postmenopausal women, aged 50 to 79 years, without prior breast cancer, including 18.6% of minority race/ethnicity, were enrolled..Women were randomly assigned to the dietary modification intervention group (40% [n = 19,541]) or the comparison group (60% [n = 29,294]). The intervention was designed to promote dietary change with the goals of reducing intake of total fat to 20% of energy and increasing consumption of vegetables and fruit to at least 5 servings daily and grains to at least 6 servings daily. Comparison group participants were not asked to make dietary changes..Invasive breast cancer incidence..Dietary fat intake was significantly lower in the dietary modification intervention group compared with the comparison group. The difference between groups in change from baseline for percentage of energy from fat varied from 10.7% at year 1 to 8.1% at year 6. Vegetable and fruit consumption was higher in the intervention group by at least 1 serving per day and a smaller, more transient difference was found for grain consumption. The number of women who developed invasive breast cancer (annualized incidence rate) over the 8.1-year average follow-up period was 655 (0.42%) in the intervention group and 1072 (0.45%) in the comparison group (hazard ratio, 0.91; 95% confidence interval, 0.83-1.01 for the comparison between the 2 groups). Secondary analyses suggest a lower hazard ratio among adherent women, provide greater evidence of risk reduction among women having a high-fat diet at baseline, and suggest a dietary effect that varies by hormone receptor characteristics of the tumor..Among postmenopausal women, a low-fat dietary pattern did not result in a statistically significant reduction in invasive breast cancer risk over an 8.1-year average follow-up period. However, the nonsignificant trends observed suggesting reduced risk associated with a low-fat dietary pattern indicate that longer, planned, nonintervention follow-up may yield a more definitive comparison..ClinicalTrials.gov Identifier: NCT00000611.

Journal of clinical epidemiology, 58(4), 378-82. doi:10.1016/j.jclinepi.2004.10.013More infoThis cross-sectional descriptive analysis sought to determine if a healthy volunteer effect can be demonstrated among smokers selected to participate in a dietary intervention trial..Body mass index (BMI), body fat, physical activity, dietary intake, and plasma concentration of antioxidant nutrients and carotenoids were assessed cross-sectionally, at the time of enrollment into a dietary intervention trial, among 136 adult smokers..Mean BMI was below national age- and gender-specific averages as was prevalence of overweight and obesity. Physical activity was reported to average 15.4 h/wk. Compared with other sample populations of smokers, our smokers reported lower total fat and cholesterol intakes, higher vitamin C and beta-carotene intakes, and generally equal vitamin E intakes. Plasma ascorbic acid, alpha-tocopherol, alpha- and beta-carotene, and beta-cryptoxanthin concentrations were higher than those of smokers surveyed by NHANES III..These findings suggest that a "healthy volunteer effect" can be described among adult smokers. Future dietary intervention trials among smokers should cautiously estimate sample size because smokers electing to participate may report healthier dietary patterns than other smokers. Screening criteria regarding baseline micronutrient status of smokers should be evaluated given that intervention effects may be dependent on overall health status.

Diet and biomarkers of oxidative damage in women previously treated for breast cancer.. Nutrition and cancer, 51(2), 146-54. doi:10.1207/s15327914nc5102_4More infoThis study sought to evaluate the relationship between dietary intake of fat, polyunsaturated fat, saturated fat, arachidonic acid, and selected dietary antioxidants and levels of oxidative damage as measured by urinary levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) and 8-epi-prostaglandin F2alpha (8-iso-PGF2alpha) in women previously treated for breast cancer. Two hundred two study subjects participating in the Women's Healthy Eating and Living (WHEL) study were included in this ancillary study. Dietary intakes and concentrations of urinary 8-OHdG and 8-iso-PGF2alpha were measured at baseline and 12 mo in the 179 women included in the analytical cohort. Study subjects demonstrated a significant reduction in dietary total, polyunsaturated, and saturated fat intake and a significant increase in vitamins E and C and beta-carotene intake from baseline to 12 mo. Linear mixed-models analysis using baseline and Year 1 data indicated that vitamin E intake was inversely associated with both 8-OHdG and 8-iso-PGF2alpha. 8-Iso-PGF2alpha is increased with increased body mass index (BMI) and polyunsaturated fatty acid (PUFA) intake, indicating an increase in lipid peroxidation with greater BMI and higher PUFA intake. 8-OHdG was inversely related to age but positively related to arachidonic acid, indicating an increase in DNA damage with higher intake of arachidonic acid (meat). The results of this nested case-controlled study provide potential mechanisms by which a high fruit and vegetable, low-fat diet might reduce the recurrence rate of or early-stage breast cancer.

European journal of nutrition, 44(1), 18-25. doi:10.1007/s00394-004-0487-xMore infoExcess adiposity has been shown to be associated with increased risk for breast cancer recurrence, and a plant-based eating pattern has been hypothesized to be protective. Whether a plant-based diet without specific energy goals will result in weight loss or changes in body composition in women who have been diagnosed with breast cancer has not been fully explored..This study was conducted to identify changes in body weight, anthropometric measures, and body composition over a four year period in a sub-sample of breast cancer survivors participating in a dietary intervention targeting increased intake of vegetables, fruit and fiber and decreased dietary fat intake..This randomized, controlled dietary intervention study compared longitudinal changes in intakes, body weight, waist:hip ratio (WHR), body mass index (BMI) and body composition by treatment group among fifty-two women previously treated for Stage I, II, or IIIA breast cancer from the Arizona site of the Women's Healthy Eating and Living Study. The dietary intervention aimed for eight servings of fruit and vegetables, 30 g fiber, < or = 20% total energy from fat per day, as well as daily intake of vegetable juice. The comparison group was advised to follow general dietary guidelines for cancer prevention..The dietary intervention resulted in a significant and sustained increase in fiber, fruit, vegetable, and vegetable juice consumption (p < 0.05) among intervention group subjects as compared to comparison group subjects. The first 6 months resulted in a reduction in body weight and body fat among the intervention group subjects while the comparison group subjects remained stable. Subsequent measurements, at 12, 24 or 36, and 48 months, showed no significant differences in mean body weight, BMI, WHR, or body composition by study group. Also, no significant changes in these measures were demonstrated for either study group between baseline and 48 months..The dietary intervention efforts resulted in significant changes in diet toward an increase in plant foods and a decrease in dietary fat. Changes in weight, WHR, BMI, and body composition were not different over time or by study group assignment. Interventions that promote a plant-based diet without specific energy restriction do not appear to promote changes in body weight or body composition in women who have been diagnosed with breast cancer. To adequately examine the role of energy restriction in reducing obesity-associated breast cancer recurrence, future interventions should include prescribed energy imbalance either through reduced intake and/or increased expenditure.

This study compared the ability of 2 measures of dietary intake (24-hour diet recalls and food frequency questionnaires [FFQs]) to corroborate plasma carotenoid concentrations in a subset of women participating in a diet intervention trial..Plasma carotenoid concentrations and dietary intakes, estimated from 24-hour diet recalls and FFQs, were examined at baseline and 1 year later in a subset of 395 study participants (197 intervention and 198 comparison group). We used longitudinal models to examine associations between estimated intakes and plasma carotenoid concentrations. These analyses were stratified by study group and adjusted for body mass index (BMI), plasma cholesterol concentration, and total energy intake. We conducted simulations to compare mean-squared errors of prediction of each assessment method..In mixed-effects models, the estimated carotenoid intakes from both dietary assessment methods were strongly associated with plasma concentrations of alpha-carotene, beta-carotene, and lutein. Furthermore, modeling the 2 sources of intake information as joint predictors reduced the prediction error..These findings underscore the importance of using multiple measures of dietary assessment in studies examining diet-disease associations.

The Journal of nutrition, 134(2), 452-8. doi:10.1093/jn/134.2.452More infoAlthough a large body of evidence suggests that diet may play an important role in cancer prevention, randomized controlled trials reported to date have not achieved sufficient increases in protective micronutrients and phytochemicals to adequately test the hypothesis that diet can reduce cancer risk. The Women's Healthy Eating and Living (WHEL) Study, a randomized controlled trial of the role diet modification may play in future breast cancer events, introduced an innovative theory-based telephone counseling intervention to teach participants to consume a high fiber, low fat diet emphasizing vegetables and fruits rich in carotenoids and other potentially protective phytochemicals. This report examines the baseline to 12-mo changes in dietary intakes of 2970 participants, assessed through 24-h recalls and validated with plasma carotenoid concentrations. At 12 mo, the intervention group reported a significantly increased daily vegetable intake (+vegetable juice) of 7.1 servings (+82%) and fruit intake of 3.9 servings (+18%). Fiber intake increased from 3.04 to 4.16 g/(MJ. d), whereas energy from fat decreased significantly from 28.6 to 23.7%. Plasma carotenoid concentrations increased significantly, i.e., alpha-carotene (+223%); beta-carotene (+87%); lutein (+29%); and lycopene (+17%). In the comparison group, dietary intake and plasma carotenoid concentrations were essentially identical to those of the intervention group at baseline and were unchanged at 12 mo. The WHEL Study showed that a telephone counseling intervention can achieve major increases in micronutrient- and phytochemical-rich vegetables, fruit and fiber intakes, enabling an investigation of the potential cancer preventive effects of these food components.

The Journal of nutrition, 134(2), 342-7. doi:10.1093/jn/134.2.342More infoDiet intervention trials are currently testing whether reduced fat intake can reduce the risk and progression of breast cancer. Energy from dietary fat is generally replaced by energy from carbohydrate in these studies, and altering the proportion of energy from dietary carbohydrate and fat has been shown to affect plasma lipid concentrations in controlled feeding studies. The purpose of this study was to examine the effect of increased carbohydrate and reduced fat intakes on plasma lipids in a randomized, controlled trial that is testing the effect of diet modification on risk for recurrence and survival in women previously treated for breast cancer. Plasma concentrations of lipids and related factors were measured at enrollment and 1-y follow-up in 393 women enrolled in the trial. Dietary goals for the intervention group focused on an increase in vegetable, fruit and fiber intakes, and reduced fat intake. Women assigned to the intervention group significantly reduced fat intake (from 28.1 to 21.0% of energy), and significantly increased intakes of carbohydrate (from 56.9 to 65.3% of energy) and fiber (from 21.0 to 29.6 g/d) (P < 0.05). Body weight did not change significantly in either study group. A small but significant increase in fasting plasma triacylglycerol concentration, and decreases in HDL cholesterol and apoprotein-A1 concentrations, were observed in the intervention group (P < 0.05) but not in the comparison group. Changes in total cholesterol, LDL cholesterol, apoprotein-B, lipoprotein (a), and insulin concentrations, and in the LDL cholesterol/HDL cholesterol ratio, were not observed in either group. The lipid responses that were observed in this study provide biological evidence that validates the self-reported change in dietary intakes of fat and carbohydrate in response to the intervention efforts. The degree of change in these lipid concentrations was small and does not suggest increased cardiovascular disease risk.

Journal of the American Dietetic Association, 104(5), 814-26. doi:10.1016/j.jada.2004.03.015More infoIt is the position of the American Dietetic Association that functional foods, including whole foods and fortified, enriched, or enhanced foods, have a potentially beneficial effect on health when consumed as part of a varied diet on a regular basis, at effective levels. The Association supports research to define further the health benefits and risks of individual functional foods and their physiologically active components. Dietetics professionals will continue to work with the food industry, the government, the scientific community, and the media to ensure that the public has accurate information regarding this emerging area of food and nutrition science. Knowledge of the role of physiologically active food components, from both phytochemicals and zoochemicals, has changed the role of diet in health. Functional foods have evolved as food and nutrition science has advanced beyond the treatment of deficiency syndromes to reduction of disease risk. This position reviews the definition of functional foods, their regulation, and the scientific evidence supporting this emerging area of food and nutrition. Foods can no longer be evaluated only in terms of macronutrient and micronutrient content alone. Analyzing the content of other physiologically active components and evaluating their role in health promotion will be necessary. The availability of health-promoting functional foods in the US diet has the potential to help ensure a healthier population. However, each functional food should be evaluated on the basis of scientific evidence to ensure appropriate integration into a varied diet.

It also identifies correlates and multivariate predictors of physical and mental HRQOL. 2582 women who were up to four years post-treatment for early stage breast cancer completed the RAND-36 Health Survey and reported personal and cancer-related information. Participants reported generally high HRQOL that was comparable to norms for women in the general population and other women with breast cancer. In multivariate analyses, better physical HRQOL was associated with fewer psychological symptoms, lower body mass index, better sleep quality, and more physical activity. Better mental HRQOL was associated with better sleep quality, fewer life events, less pain, and fewer gastrointestinal symptoms. Interventions targeting psychosocial symptoms, weight reduction, physical activity, sleep hygiene, and pain could result in improved HRQOL in these women.

The majority of available research consists of case-control studies, but the number of clinical trials is growing. The dietary recommendations to reduce gastrointestinal cancer risk include lowering total energy, fat, and saturated fat intake; avoidance of grilled and smoked foods; avoidance of alcohol; and increasing intake of fruits, vegetables, and fiber. Studies of esophageal cancer support these dietary approaches, with the exception of dietary fat reduction and increased green tea intake. For gastric cancer, consuming additional fruits and vegetables, including those high in ascorbic acid, may reduce risk, and the capacity for diet to alter Helicobacter pylori infection should be explored. Recent interventional trials do not support a role for high-fiber or low-fat diets in reducing development of colon adenomas, although the evidence does not rule out efficacy at earlier stages of disease. Finally, the evidence for a relationship between pancreatic cancer and diet remains sparse and warrants additional investigation.

American journal of epidemiology, 157(8), 754-62. doi:10.1093/aje/kwg025More infoMeasurement of dietary change was assessed in a systematic quota subsample (n = 397) of women recruited into the Women's Healthy Eating and Living Study between 1996 and 1998, a multicenter, randomized dietary intervention trial among breast cancer survivors. Women from the intervention and comparison arms completed the Arizona Food Frequency Questionnaire (AFFQ) and 24-hour dietary recalls at baseline (prerandomization) and at year 1 (postrandomization). Both dietary measurement methods demonstrated significant changes in intake of key intervention-associated nutrients at year 1 in the intervention group subjects compared with minimal or no change in the comparison group subjects. The reliability of the AFFQ and recalls was measured in the comparison group and showed correlations of 0.63 and 0.43, respectively. Both instruments captured differences in dietary intake associated with the diet intervention. These results demonstrate the utility of using a multimode, multimethod approach (AFFQ and 24-hour dietary recalls) to measure differences in self-reported dietary intake over time as shown in this dietary intervention trial being conducted among breast cancer survivors.

Obstetrical & Gynecological Survey, 58(11), 735-737. doi:10.1097/01.ogx.0000093674.44946.d6More infoThe large-scale Women's Health Initiative has confirmed that, in postmenopausal women, combined estrogen/ progestin therapy entails an increased risk of invasive breast cancer. The investigators have now explored this relationship in detail, characterizing the cancers that developed and seeking to learn whether hormonal effects on the mammogram can influence diagnosis. A total of 16,608 postmenopausal women 50 to 79 years of age, all with an intact uterus, were randomly assigned to receive active treatment (0.625 mg conjugated equine estrogens plus 2.5 mg medroxyprogesterone acetate daily in a single tablet) or placebo. The participants, seen at 40 clinical centers, were to be followed from 1993 to 1998 by annual clinical breast examinations and mammograms, but the trial was ended after a mean interval of 5.2 years. Intent-to-treat analyses demonstrated a hazard ratio of 1.24 for both total cancers and invasive cancers in women given hormone therapy compared with the placebo group. There was some suggestion of an increased risk for in situ breast cancer in hormone-treated women. An increased risk of breast cancer in treated women emerged after 3 years in those not receiving hormones previously and after 2 years in previously treated women. The findings were similar when women in specific risk categories were analyzed, and race and ethnicity were not significant factors. Invasive cancers associated with combined hormone therapy were larger than those in placebo recipients, more likely to be node-positive, and diagnosed when more advanced. There was, however, no difference in tumor grade or in the distribution of histologic types of breast cancer. After the first year, hormone-treated women more often had abnormal or highly suspicious mammograms than did those given placebo. In this prospective, randomized trial, combined estrogen/progestin treatment of postmenopausal women increased both breast cancer risk and the frequency of abnormal mammograms requiring medical assessment. In addition, cancers in treated women were more advanced when diagnosed than was the case for placebo recipients.

Controlled clinical trials, 23(6), 728-56. doi:10.1016/s0197-2456(02)00241-6More infoThe Women's Healthy Eating and Living (WHEL) Study is a multisite randomized controlled trial of the effectiveness of a high-vegetable, low-fat diet, aimed at markedly raising circulating carotenoid concentrations from food sources, in reducing additional breast cancer events and early death in women with early-stage invasive breast cancer (within 4 years of diagnosis). The study randomly assigned 3088 such women to an intensive diet intervention or to a comparison group between 1995 and 2000 and is expected to follow them through 2006. Two thirds of these women were under 55 years of age at randomization. This research study has a coordinating center and seven clinical sites. Randomization was stratified by age, stage of tumor and clinical site. A comprehensive intervention program that includes intensive telephone counseling, cooking classes and print materials helps shift the dietary pattern of women in the intervention. Through an innovative telephone counseling program, dietary counselors encourage women in the intervention group to meet the following daily behavioral targets: five vegetable servings, 16 ounces of vegetable juice, three fruit servings, 30 g of fiber and 15-20% energy from fat. Adherence assessments occur at baseline, 6, 12, 24 or 36, 48 and 72 months. These assessments can include dietary intake (repeated 24-hour dietary recalls and food frequency questionnaire), circulating carotenoid concentrations, physical measures and questionnaires about health symptoms, quality of life, personal habits and lifestyle patterns. Outcome assessments are completed by telephone interview every 6 months with medical record verification. We will assess evidence of effectiveness by the length of the breast cancer event-free interval, as well as by overall survival separately in all the women in the study as well as specifically in women under and over the age of 55 years.

The American journal of clinical nutrition, 73(6), 1107-12. doi:10.1093/ajcn/73.6.1107More infoNinety-eight percent of medical schools report nutrition as a component of medical education. However, most schools do not have an identifiable nutrition curriculum. Medical schools that do include nutrition have not evaluated its effect on clinical skills..The objective was to determine the efficacy of an integrated undergraduate medical curriculum to increase the quantity of nutrition instruction and to advance nutrition clinical skills demonstrated by medical students..A quasiexperimental design was constructed to determine whether an integrated nutrition curriculum increased the performance on nutrition-oriented clinical examinations of medical school classes that received 1, 2, or 3 y of the curriculum. The evaluation of the curriculum focused on 3 areas: 1) hours of nutrition instruction, 2) the application of nutrition within a clinical setting, and 3) perceptions about the nutrition curriculum. The Objective Structured Clinical Examination (OSCE) nutrition score was compared between graduating classes by use of analysis of variance. Data from the American Association of Medical Colleges were analyzed to determine the change in the proportion of students who reported that the amount of time devoted to nutrition was adequate..The implementation of the integrated nutrition curriculum resulted in a doubling of the total hours of required instruction in the medical curriculum (35 compared with 75 h). The mean (+/-1 SEM) OSCE nutrition score significantly improved after the implementation of the curriculum (41.7 +/- 0.9% compared with 50.6 +/- 1.1%) and the percentage of students who reported that the amount of nutrition taught during medical school was inadequate decreased (68.4% compared with 11.5%)..Medical students improved their clinical nutrition practice skills through participation in an integrated nutrition curriculum.

METHODS Weight change in response to diet intervention was examined in 1010 women who had completed treatment for Stage I, Stage II, or Stage IIIA (American Joint Committee on Cancer staging system) primary operable breast cancer during their first year of participation in a randomized, controlled, diet intervention trial to reduce risk of recurrence. Diet intervention was performed by telephone counseling and promoted a low fat diet that also was high in fiber, vegetables, and fruit. The comparison group was provided with general dietary guidelines to reduce disease risk. Multiple linear regression models were used to examine the relations among demographic and personal characteristics, changes in diet composition and exercise level, and change in body weight or body mass index. RESULTS The average weight change in the 1-year period was 0.04 kg for the intervention group and 0.46 kg for the comparison group. For the total group, body weight was stable (± 5% baseline weight) for 743 women (74%), whereas 114 (11%) lost weight, and 153 (15%) gained weight. These distributions were similar in the two study groups inclusive of all study participants and for only those women with a baseline body mass index of ≥ 25 kg/m2. Initial body mass index and changes in fiber and vegetable intakes, but not change in percent of energy obtained from fat, were associated independently with change in weight or body mass index. CONCLUSIONS For most women at risk for breast cancer recurrence, diet intervention to promote a reduction in fat intake was not associated with significant weight loss. Testing the effect of a substantial change in diet composition on risk for breast cancer recurrence is unlikely to be confounded by weight loss in subjects who were the recipients of intensive intervention efforts.

Integrative Medicine, 2(1), 37-42. doi:10.1016/s1096-2190(99)00006-2More infoAbstract Parkinson's disease is a common idiopathic neurodegenerative disease affecting an increasing number of elderly people. The disease usually manifests with a classical triad of symptoms (tremor, rigidity, and akinesia) and is considered to be the result of dopamine deficiency in the brain. Among the theories to explain the ethiopathogenecity of Parkinson's disease are some endogenous mechanisms, such as mitochondrial dysfunction, oxidative stress, action of excitotoxins, deficient neurotrophic factors, and dysimmunity, and some environmental factors, such as undesirable nutritional status. The cornerstone of Parkinson's disease therapy is the exogenous supplementation of levodopa, the amino acid precursor of dopamine. For most patients, however, this treatment fails over time and other alternative therapies are pursued. The purpose of this paper is to explore the lines of evidence suggesting the roles for Mind–Body medicine, nutrition, and vitamin and herbal supplements in the integrative approach to the medical care of patients with Parkinson's disease. It is proposed that many parkinsonian symptoms can be treated, controlled, and even reversed by adopting such an integrative and comprehensive approach.

Journal of Nutraceuticals, Functional & Medical Foods, 1(1), 33-45. doi:10.1300/j133v01n01_04More infoThe National Cancer Institute estimates that one in three cancer deaths is related to diet, and that 8 of 10 cancers have a nutrition/diet component. Phytochemicals (food components derived from naturally occurring ingredients) and functional foods (modified foods or food ingredients that may provide health benefits beyond those offered by the traditional nutrients they contain) are actively being investigated for their health-promoting potential. Phytochemicals are present in a number of frequently consumed foods, especially fruits, vegetables, grains, legumes, and seeds, and in a number of less frequently consumed foods such as licorice, soy, and green tea. Health benefits of these foods are best obtained through the consumption of a varied diet based on normal food supply. Growing scientific evidence supports the role of phytochemicals and functional foods in the prevention and treatment of at least four of the leading causes of death in this country, cancer, diabetes, cardiovascular disease, and hypertension, and With the prevention and/or treatment of other medical ailments including neural tube defects, osteoporosis, abnormal bowel function, and arthritis. The current emphasis on cost effective health care highlights the importance of dietary changes to optimize health, and the food industry is responding to consumer demands for a more healthful food supply by developing nutrient rich food products, including products lower in fat and sodium, that are consistent with the US Dietary Guidelines for Americans. The 1990 Nutrition Labeling and Education Act (NLEA) requires consistent and informative labeling of all food items, providing consumers with a reliable source of relevant nutrition information. Professional dieticians are urged to take an active role in disseminating information about phytochemicals and functional foods, and in promoting their beneficial consumption.

Journal of The American Dietetic Association, 97(9), A27. doi:10.1016/s0002-8223(97)00413-6More infoAbstract LEARNING OUTCOME : To determine the potential for improving quality of life and nutritional status for patients undergoing treatment for gastrointestinal (GI) cancer through the provision of a formalized nutrition intervention program. Many cancer patients have detectable malnutrition during the course of their disease due to the cancer or any of the commonly used treatment modalities. The adverse impact of malnutrition on prognosis, productivity, and quality of life has been documented in previous studies, but the benefits of nutrition interventions have been less well documented and so remain controversial. A nutrition intervention program does not exist at an NCI designated outpatient cancer center in the Southwest; therefore, the goals of this study were two-fold: 1) to conduct a retrospective chart review to determine the prevalence and degree of malnutrition and if delays in treatment related to the degree of malnutrition in patients who had completed therapy for GI cancer, and 2) to conduct a pilot study to determine if a formalized nutrition screening and intervention program brings about a positive change in quality of life, nutritional status, and timing of therapy for patients undergoing aggressive treatment for GI cancer. The results of the chart review (n=30) revealed: 1) weight loss correlated with delays in treatment (p=.03), and 2) the presence of malnutrition at the onset of therapy predicts further weight loss during therapy (p=.04). The results of the subsequent pilot study (n=25) showed that 52% of patients had malnutrition at the onset of therapy. With nutrition screening, counseling, and monitoring (without the use of specialized nutrition support), 72% of patients maintained or improved nutritional status while on therapy. Treatment delays were weakly associated with the presence of malnutrition but were not statistically significant. Quality of life scores (using the Functional Assessment of Anorexia/Cachexia Treatment questionnaire) showed maintenance or improvement in scores for 80% of the patients. Future research is planned to conduct a prospective randomized controlled clinical trial to determine the benefits of a formalized nutrition screening and intervention program with regard to quality of life and nutritional status for cancer patients.

This future is now. All over the United States dietitians are redefining their roles and contributions to the care of patients.’ No longer can we find comfort in the familiar or lament the infamous “that’s not my job.” To survive in a cost-conscious health care environment we must be versatile, creative, and willing to take on new roles professionally. Equipping ourselves with the skills to perform a variety of patient care activities will mean job security. We cannot be territorial with our knowledge and expertise. Remember, the average patient will soon have computer access to the nutrient analysis information and many of the nutritional status assessment measures we currently provide.

The philosophy that food can be health promoting beyond its nutritional value is gaining acceptance within the public arena and among the scientific community as mounting research links diet/food components to disease prevention and treatment. Dietitians are uniquely qualified and positioned to translate the available sound scientific evidence into practical dietary applications for the consumer and to provide the food industry and the government with valuable insight and expertise for future research, product development, and regulation of phytochemicals and functional foods. Increasing the availability of healthful foods, including functional foods, in the American diet is critical to ensuring a healthier population. As the nutrition experts, dietetics professionals must be the leaders in this new, exciting, and meaningful field as it evolves.

Automated segmentation of breast fat-water MR images using empirical analysis. In 2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 1018-1022.More infoBreast density (BD) has been advocated as a risk factor for the development of breast cancer. BD is typically measured from mammograms. However for longitudinal studies of patients at risk, BD can be better assessed using MRI due to the lack of ionizing radiation and the 3D capabilities of the technique. A fat-water (FW) imaging technique called RAD-GRASE was developed to acquire images of the entire breast in a few minutes and can generate fat-fraction maps, which can be used to assess BD. The time consuming manual segmentation on ~19 slices per exam can be challenging. In this paper, we present a method to automatically segment the breast tissue in FW images and yield FW profiles of the region of interest (ROIs).
