Biography
Dr. Bea is a physiological scientist, focused on body composition and chronic disease research, with an emphasis on cancer. Dr. Bea was an R25T Cancer Prevention and Control Fellow at the University of Arizona (UA) and, subsequently, the program coordinator for 5 years. She is currently Co-director for the Body Composition Research Laboratory and the Collaboratory for Metabolic Disease Prevention and Treatment Operations Committee Co-chair at UA. Dr. Bea is an investigator for the National Women’s Health Initiative and previously directed the University of Arizona Nutrition Network (UANN) evaluation program throughout the state. Dr. Bea is a member of the NRG Cancer Prevention and Control Committee and a reviewer for the American Cancer Society Institutional Research Grant. As an expert in body composition imaging, lifestyle interventions, circulating biomarkers, and genetics, Dr. Bea has made significant strides in understanding how to tailor interventions to optimize body composition and health. Among the contributions was her investigation into weight loss in breast cancer survivors evaluating macronutrient composition, metabolic regulation, and change in body composition. More recently, Dr. Bea has begun to address cancer health disparities as PI of a physical activity intervention in the Native American Cancer Prevention Project (NCI U54).

American Society of Clinical Oncology. Annual Meeting(pp e22-e33).More infoObservational evidence has consistently linked excess adiposity and inactivity to increased breast cancer risk and to poor outcomes in individuals diagnosed with early-stage, potentially curable breast cancer. There is less information from clinical trials testing the effect of weight management or physical activity interventions on breast cancer risk or outcomes, but a number of ongoing trials will test the impact of weight loss and other lifestyle changes after cancer diagnosis on the risk of breast cancer recurrence. Lifestyle changes have additional benefits beyond their potential to decrease primary or secondary breast cancer risk, including improvements in metabolic parameters, reduction in the risk of comorbidities such as diabetes and heart disease, improvement of physical functioning, and mitigation of side effects of cancer therapy. Despite these myriad benefits, implementation of lifestyle interventions in at-risk and survivor populations has been limited to date. This article reviews the evidence linking lifestyle factors to breast cancer risk and outcomes, discusses completed and ongoing randomized trials testing the impact of lifestyle change in primary and secondary breast cancer prevention, and reviews efforts to implement and disseminate lifestyle interventions in at-risk and breast cancer survivor populations.

Menopause (New York, N.Y.), 30(2), 186-192.More infoMany dietary polyphenols with potential health-promoting benefits undergo hepatic conjugation and circulate as inactive glucuronides that can be cleaved by ß-glucuronidase to reform the bioactive aglycone. Although indirect evidence suggests estrogen may induce ß-glucuronidase, little is known about ß-glucuronidase regulation across women's reproductive lifespan. Correlates of serum ß-glucuronidase activity in healthy premenopausal versus postmenopausal women were therefore examined.

A subset of 43 participants were scanned on both DXA devices. DXA-derived VAT and SAT at the 4th lumbar vertebrae (5 cm wide) were analyzed using APEX software (v4.0, Hologic, Inc., Marlborough, MA). MRI VAT and SAT areas for the corresponding DXA region of interest were quantified using sliceOmatic software (v5.0, Tomovision, Magog, Canada). Pearson correlations between MRI and DXA-derived VAT and SAT were computed, and a Bland-Altman analysis was performed..Participants were primarily non-Hispanic white (86%) with a mean age of 70.51 ± 5.79 years and a mean BMI of 27.33 ± 5.40 kg/m2. Correlations between MRI and DXA measured VAT and SAT were 0.90 and 0.92, respectively (p ≤ 0.001). Bland-Altman plots showed that DXA-VAT slightly overestimated VAT on the QDR4500 (-3.31 cm2); this bias was greater in the smaller subset measured on the older DXA model (QDR2000; -30.71 cm2). The overestimation of DXA-SAT was large (-85.16 to -118.66 cm2), but differences were relatively uniform for the QDR4500..New software applied to historic Hologic DXA scans provide estimates of VAT and SAT that are well-correlated with criterion MRI among postmenopausal women.

However, factors associated with physical activity among older breast cancer survivors are not well-understood..Participants were enrolled in the Women's Health Initiative (WHI) Life and Longevity After Cancer (LILAC) study. Descriptive statistics, multiple linear regression, and relative risk [RR] regression were used to assess the association of demographic, clinical, physical and psychosocial variables with the total duration of and participation in physical activity among postmenopausal breast cancer survivors. Age-specific correlates (65-74 years vs. 75-84 years vs. ≥85 years) of physical activity were also examined..The majority of participants (n = 3710, mean age = 78.8 ± 5.9) were white (90.7%) and had in situ/localized breast cancer (78.9%). Women who had higher education (RR = 1.47 for graduate/professional school versus high school or less, 95% CI: 1.32, 1.63), higher self-rated health (RR = 1.04 for 10 point increase, 95% CI:1.02, 1.07), higher physical functioning (RR = 1.03 for 5 point increase, 95% CI: 1.02, 1.04), and higher social support (RR = 1.41 for social support all of the time versus none of the time, 95% CI: 1.01, 1.96), were more likely to engage in any physical activity. Similar results were observed for duration of physical activity. Among women aged

Journal of bone and mineral research : the official journal of the American Society for Bone and Mineral Research, 36(1), 123-132. doi:10.1002/jbmr.4168More infoObesity and osteoporosis remain two major public health concerns. Soft tissue composition and bone are interrelated; however, it is still not well understood how changes in adiposity during adolescence affect bone development. The aim of this study was to assess how changes in DXA-derived total body lean mass (TBLM) and total body fat mass (TBFM) associate with 2-year changes in bone outcomes at the 20% femur, 66% tibia, 66% radius, and 4% tibia, as measured by pQCT, during the years surrounding the onset of menarche in a cohort of 9- to 12-year-old (baseline) adolescent girls (70% Hispanic). From baseline to 2-year follow-up, girls showed statistically significant increases in all bone outcomes, except radial endosteal circumference. In separate linear regression models, change in TBLM and change in TBFM were both positively associated with 2-year changes in bone outcomes at all measured bone sites, after controlling for relevant covariates. However, when change in TBLM and change in TBFM were included in the same model, change in TBLM was the predominant predictor of bone outcomes, explaining 4% to 14% of the variance in bone strength outcomes. Change in TBFM remained a positive predictor of tibia polar strength strain index (SSIp) (2% variance explained). A significant interaction between change in TBFM and menarcheal status was identified at the radius for SSIp and indicated that greater gains in TBFM were beneficial for SSIp in girls that were premenarcheal at baseline but detrimental for girls who were postmenarcheal at baseline. The overall findings suggest that changes in TBLM during the peripubertal years have a greater influence on bone outcomes than changes in TBFM. While gains in TBFM might benefit the weight bearing 66% tibia, greater gains in TBFM may be detrimental to bone development at the non-weight bearing 66% radius after the onset of menarche. © 2020 American Society for Bone and Mineral Research (ASBMR).

Predictive Value of DXA Appendicular Lean Mass for Incident Fractures, Falls, and Mortality, Independent of Prior Falls, FRAX, and BMD: Findings from the Women's Health Initiative (WHI).. Journal of bone and mineral research : the official journal of the American Society for Bone and Mineral Research, 36(4), 654-661. doi:10.1002/jbmr.4239More infoIn the Women's Health Initiative (WHI), we investigated associations between baseline dual-energy X-ray absorptiometry (DXA) appendicular lean mass (ALM) and risk of incident fractures, falls, and mortality (separately for each outcome) among older postmenopausal women, accounting for bone mineral density (BMD), prior falls, and Fracture Risk Assessment Tool (FRAX® ) probability. The WHI is a prospective study of postmenopausal women undertaken at 40 US sites. We used an extension of Poisson regression to investigate the relationship between baseline ALM (corrected for height2 ) and incident fracture outcomes, presented here for major osteoporotic fracture (MOF: hip, clinical vertebral, forearm, or proximal humerus), falls, and death. Associations were adjusted for age, time since baseline and randomization group, or additionally for femoral neck (FN) BMD, prior falls, or FRAX probability (MOF without BMD) and are reported as gradient of risk (GR: hazard ratio for first incident fracture per SD increment) in ALM/height2 (GR). Data were available for 11,187 women (mean [SD] age 63.3 [7.4] years). In the base models (adjusted for age, follow-up time, and randomization group), greater ALM/height2 was associated with lower risk of incident MOF (GR = 0.88; 95% confidence interval [CI] 0.83-0.94). The association was independent of prior falls but was attenuated by FRAX probability. Adjustment for FN BMD T-score led to attenuation and inversion of the risk relationship (GR = 1.06; 95% CI 0.98-1.14). There were no associations between ALM/height2 and incident falls. However, there was a 7% to 15% increase in risk of death during follow-up for each SD greater ALM/height2 , depending on specific adjustment. In WHI, and consistent with our findings in older men (Osteoporotic Fractures in Men [MrOS] study cohorts), the predictive value of DXA-ALM for future clinical fracture is attenuated (and potentially inverted) after adjustment for femoral neck BMD T-score. However, intriguing positive, but modest, associations between ALM/height2 and mortality remain robust. © 2021 The Authors.

This study investigated whether social stress is prospectively associated with fracture incidence among racially and ethnically diverse, postmenopausal women..Data from 160 709 postmenopausal women in the Women's Health Initiative was analysed using Cox proportional hazards regression models to examine prospective associations of social stress with time to total and hip fracture incidence. Self-reported questionnaires measuring social strain, social functioning and social support were used to assess social stress..Age and race/ethnicity modified associations between social stress and total and hip fractures. HRs for the associations between higher social support (indicating lower social stress) and total fractures among those age 50-59 years were 0.92 (95% CI: 0.90 to 0.94); HR=0.94 (95% CI: 0.93 to 0.95) for those age 60-69 years and HR=0.96 (95% CI: 0.95 to 0.98) for those age 70-79 years. Higher social strain was associated with greater hip fracture incidence among Native American women (HR=1.84, 95% CI: 1.10 to 3.10), Asian women (HR=1.37, 95% CI: 1.01 to 1.86) and white women (HR=1.04, 95% CI: 1.01 to 1.08)..Identifying population patterns of fracture incidence as biological expressions of social environments reveals how race/ethnic specific social environmental factors influence disparities in fractures.

Journal of cancer education : the official journal of the American Association for Cancer Education, 35(3), 493-500. doi:10.1007/s13187-019-01487-5More infoNative Americans experience cancer-related health disparities. Yet, little is known about the current cancer experience in one of the largest Native American tribe, Navajo. A qualitative study of among Navajo cancer survivors, in which focus groups and individual interviews included questions related to perceptions of cancer causes, prevention, and treatment, allowed us to evaluate several aspects of the cancer experience from the Navajo perspective. An experienced, bilingual facilitator led the discussions using a standardized guide. Discussions were audio-recorded, documented by field notes, translated, as needed, and transcribed. NVivo software was used to summarize major themes according to the PEN-3 and health belief models. Navajo cancer survivors (N = 32) were both males (n = 13) and females (n = 19) that had been previously diagnosed with a variety of cancers: colorectal, breast, ovarian, cervical, esophageal, gall bladder, stomach, prostate, kidney, and hematologic. Many survivors had accurate knowledge of risk factors for cancer. Barriers to screening and clinical care included language, expense, geography, fear, lack of information, skepticism related to Western medicine, and treatment side effects. While some survivors experienced familial support, others were isolated from the family and community due to the perspective of cancer as a contagion. However, resilience, hope, trust in select community organizations, a desire to restore balance, and to support younger generations were positive attributes expressed regarding the treatment and recovery process. These evaluations need to be replicated across a larger cross-section of the Native cancer survivor community.

Forty articles were identified that assessed the relationship between accelerometry-derived physical activity and bone outcomes in adolescents. Physical activity was positively associated with bone strength in peri-pubertal males, with less consistent evidence in females. Physical activity (PA) is recommended to optimize bone development in childhood and adolescence; however, the influence of day-to-day PA on bone development is not well defined. The aim of this review was to describe the current evidence for objectively measured PA on bone outcomes in healthy children and adolescents. MEDLINE, Embase, Cochrane Library, Scopus, Web of Science, CINAHL, PsycInfo, and ClinicalTrials.gov were searched for relevant articles up to April 2020. Studies assessing the relationship between accelerometry-derived PA and bone outcomes in adolescents (6-18 years old) were included. Two reviewers independently screened studies for eligibility, extracted data, and rated study quality. Forty articles met inclusion criteria (25 cross-sectional, 15 longitudinal). There was significant heterogeneity in accelerometry methodology and bone outcomes measured. Studies in males indicated a significant, positive relationship between moderate to vigorous PA (MVPA) and bone outcomes at the hip and femur, particularly during the peri-pubertal years. The results for MVPA and bone outcomes in females were mixed. There was a paucity of longitudinal studies using pQCT and a lack of data regarding how light PA and/or impact activity influences bone outcomes. The current evidence suggests that objectively measured MVPA is positively associated with bone outcomes in children and adolescents, especially in males. However, inconsistencies in methodology make it difficult to determine the amount and type of PA that leads to favorable bone outcomes. Given that the majority of research has been conducted in Caucasian adolescents, further research is needed in minority populations.

The Effects of Reverse Causality and Selective Attrition on the Relationship Between Body Mass Index and Mortality in Postmenopausal Women. American journal of epidemiology, 188(10), 1838-1848.More infoConcerns about reverse causality and selection bias complicate the interpretation of studies of body mass index (BMI, calculated as weight (kg)/height (m)2) and mortality in older adults. The objective of this study was to investigate methodological explanations for the apparent attenuation of obesity-related risks in older adults. We used data from 68,132 participants in the Women's Health Initiative (WHI) clinical trial for this analysis. All of the participants were postmenopausal women aged 50-79 years at baseline (1993-1998). To examine reverse causality and selective attrition, we compared rate ratios from inverse probability of treatment- and censoring-weighted Poisson marginal structural models with results from an unweighted adjusted Poisson regression model. The estimated mortality rate ratios and 95% confidence intervals for BMIs of 30.0-34.9, 35.0-39.9 and ≥40.0 were 0.86 (95% confidence interval (CI): 0.77, 0.96), 0.85 (95% CI: 0.72, 0.99), and 0.88 (95% CI: 0.72, 1.07), respectively, in the unweighted model. The corresponding mortality rate ratios were 0.96 (95% CI: 0.86, 1.07), 1.12 (95% CI: 0.97, 1.29), and 1.31 95% CI: (1.08, 1.57), respectively, in the marginal structural model. Results from the inverse probability of treatment- and censoring-weighted marginal structural model were attenuated in low BMI categories and increased in high BMI categories. The results demonstrate the importance of accounting for reverse causality and selective attrition in studies of older adults.

Perceptions of Cancer Causes, Prevention, and Treatment Among Navajo Cancer Survivors. Journal of cancer education : the official journal of the American Association for Cancer Education.More infoNative Americans experience cancer-related health disparities. Yet, little is known about the current cancer experience in one of the largest Native American tribe, Navajo. A qualitative study of among Navajo cancer survivors, in which focus groups and individual interviews included questions related to perceptions of cancer causes, prevention, and treatment, allowed us to evaluate several aspects of the cancer experience from the Navajo perspective. An experienced, bilingual facilitator led the discussions using a standardized guide. Discussions were audio-recorded, documented by field notes, translated, as needed, and transcribed. NVivo software was used to summarize major themes according to the PEN-3 and health belief models. Navajo cancer survivors (N = 32) were both males (n = 13) and females (n = 19) that had been previously diagnosed with a variety of cancers: colorectal, breast, ovarian, cervical, esophageal, gall bladder, stomach, prostate, kidney, and hematologic. Many survivors had accurate knowledge of risk factors for cancer. Barriers to screening and clinical care included language, expense, geography, fear, lack of information, skepticism related to Western medicine, and treatment side effects. While some survivors experienced familial support, others were isolated from the family and community due to the perspective of cancer as a contagion. However, resilience, hope, trust in select community organizations, a desire to restore balance, and to support younger generations were positive attributes expressed regarding the treatment and recovery process. These evaluations need to be replicated across a larger cross-section of the Native cancer survivor community.

Bone, 120, 452-458.More infoExcess weight exerts the positive effect of mechanical loading on bone during development whereas obesity-related metabolic dysfunction may have a detrimental impact. In adults, the presence of metabolic syndrome and type 2 diabetes has been associated with compromised bone density, quality, and strength, and an increased incidence of fractures. The few studies that have investigated the role of cardio-metabolic disease risk biomarkers (CMR) on bone strength in children have given conflicting results. The aim of this study was to assess the combined and independent relationships of cardio-metabolic biomarkers with total body and regional bone parameters in young girls.

Journal of the American Medical Directors Association, 20(5), 569-582.e7. doi:10.1016/j.jamda.2018.10.027More infoTo evaluate the association between nutritional status, defined on the basis of a multidimensional evaluation, and body mass index (BMI) with the risk of falls and recurrent falls in community-dwelling older people..Systematic literature review and meta-analysis..Community-dwelling older adults..A systematic literature review was conducted on prospective studies identified through electronic and hand searches until October 2017. A random effects meta-analysis was used to evaluate the relative risk (RR) of experiencing falls and recurrent falls (≥2 falls within at least 6 months) on the basis of nutritional status, defined by multidimensional scores. A random effects dose-response meta-analysis was used to evaluate the association between BMI and the risk of falls and recurrent falls..People who were malnourished or those at risk for malnutrition had a pooled 45% higher risk of experiencing at least 1 fall than were those well-nourished (9510 subjects). Increased falls risk was observed in subjects malnourished versus well-nourished [RR 1.64, 95% confidence interval (CI) 1.18-2.28; 3 studies, 8379 subjects], whereas no substantial results were observed for risk of recurrent falls. A U-shaped association was detected between BMI and the risk for falls (P < .001), with the nadir between 24.5 and 30 (144,934 subjects). Taking a BMI of 23.5 as reference, the pooled RR of falling ranged between 1.09 (95% CI 1.04-1.15) for a BMI of 17, to 1.07 (95% CI 0.92-1.24) for a BMI of 37.5. No associations were observed between BMI and recurrent falls (120,185 subjects)..The results of our work suggest therefore that nutritional status and BMI should be evaluated when assessing the risk for falls in older age.

Body composition and physical function in the Women's Health Initiative Observational Study.. Preventive medicine reports, 11, 15-22. doi:10.1016/j.pmedr.2018.05.007More infoPhysical function is critical for mobility and quality of life. We hypothesized that higher total lean mass is associated with higher physical function, and body fat inversely associated, among postmenopausal women. Women's Health Initiative Observational Study participants at Pittsburgh, PA; Birmingham, AL; and Tucson-Phoenix, AZ (1993-1998) completed dual-energy X-ray absorptiometry scans and the Rand SF-36 questionnaire at baseline and 3 y (N = 4526). Associations between quartiles (Q1-4) of lean or fat mass and physical function were tested using linear regression, adjusted for demographics, lifestyle factors, medical history, and scanner serial number. At baseline, participants had a mean ± SD age of 63.4 ± 7.4 y and BMI of 27.4 ± 5.8 kg/m2. Higher percent lean mass was positively associated with physical function at baseline (Q4, 83.6 ± 0.6 versus Q1, 74.6 ± 0.7; p < 0.001), while fat mass (kg and %) was inversely associated (e.g., Q4, 73.7 ± 0.7 versus Q1, 84.2 ± 0.7 kg; ptrend < 0.001). Physical function had declined across the cohort at 3 y; the highest relative lean mass quartile at baseline conferred a lesser decline in physical function than the lowest (Q4, -3.3 ± 0.6 versus Q1-7.0 ± 0.6; ptrend < 0.001), while the highest fat mass quartile (% and kg) conferred greater decline (ex. Kg Q4, -6.7 ± 0.7 versus Q1-2.8 ± 0.6; ptrend < 0.001). Increased fat mass (≥5%), but not lean mass, was associated with lower physical function at 3 y (p < 0.001). Adiposity, as well as lean mass, requires consideration in the prediction of physical function among postmenopausal women over time.

Journal of aging research, 2018(2018), 8491092. doi:10.1155/2018/8491092More 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 (n=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., p=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.

Bone, 113, 144-150. doi:10.1016/j.bone.2018.05.023More infoWith the high prevalence of childhood obesity, especially among Hispanic children, understanding how body weight and its components of lean and fat mass affect bone development is important, given that the amount of bone mineral accrued during childhood can determine osteoporosis risk later in life. The aim of this study was to assess the independent contributions of lean and fat mass on volumetric bone mineral density (vBMD), geometry, and strength in both weight-bearing and non-weight-bearing bones of Hispanic and non-Hispanic girls..Bone vBMD, geometry, and strength were assessed at the 20% distal femur, the 4% and 66% distal tibia, and the 66% distal radius of the non-dominant limb of 326, 9- to 12-year-old girls using peripheral quantitative computed tomography (pQCT). Total body lean and fat mass were measured by dual-energy x-ray absorptiometry (DXA). Multiple linear regression was used to assess the independent relationships of fat and lean mass with pQCT bone measures while adjusting for relevant confounders. Potential interactions between ethnicity and both fat and lean mass were also tested..Lean mass was a significant positive contributor to all bone outcomes (p < 0.05) with the exception of vBMD at diaphyseal sites. Fat mass was a significant contributor to bone strength at weight bearing sites, but did not significantly contribute to bone strength at the non-weight bearing radius and was negatively associated with radius cortical content and thickness. Bone measures did not significantly differ between Hispanic and non-Hispanic girls, although there was a significant interaction between ethnicity and fat mass with total bone area at the femur (p = 0.02) and 66% tibia (p = 0.005) as well as bone strength at the femur (p = 0.03)..Lean mass is the main determinant of bone strength for appendicular skeletal sites. Fat mass contributes to bone strength in the weight-bearing skeleton but does not add to bone strength in non-weight-bearing locations and may potentially be detrimental. Bone vBMD, geometry, and strength did not differ between Hispanic and non-Hispanic girls; fat mass may be a stronger contributor to bone strength in weight-bearing bones of Hispanic girls compared to non-Hispanic.

International journal of obesity (2005), 42(6), 1161-1176. doi:10.1038/s41366-018-0120-3More infoPhysical activity (PA) protects against a wide range of diseases. Habitual PA appears to be heritable, motivating the search for specific genetic variants that may inform efforts to promote PA and target the best type of PA for each individual..We used data from the UK Biobank to perform the largest genome-wide association study of PA to date, using three measures based on self-report (nmax = 377,234) and two measures based on wrist-worn accelerometry data (nmax = 91,084). We examined genetic correlations of PA with other traits and diseases, as well as tissue-specific gene expression patterns. With data from the Atherosclerosis Risk in Communities (ARIC; n = 8,556) study, we performed a meta-analysis of our top hits for moderate-to-vigorous PA (MVPA)..We identified ten loci across all PA measures that were significant in both a basic and a fully adjusted model (p < 5 × 10-9). Upon meta-analysis of the nine top hits for MVPA with results from ARIC, eight were genome-wide significant. Interestingly, among these, the rs429358 variant in the APOE gene was the most strongly associated with MVPA, whereby the allele associated with higher Alzheimer's risk was associated with greater MVPA. However, we were not able to rule out possible selection bias underlying this result. Variants in CADM2, a gene previously implicated in obesity, risk-taking behavior and other traits, were found to be associated with habitual PA. We also identified three loci consistently associated (p < 5 × 10-5) with PA across both self-report and accelerometry, including CADM2. We found genetic correlations of PA with educational attainment, chronotype, psychiatric traits, and obesity-related traits. Tissue enrichment analyses implicate the brain and pituitary gland as locations where PA-associated loci may exert their actions..These results provide new insight into the genetic basis of habitual PA, and the genetic links connecting PA with other traits and diseases.

Heart failure, 6(12), 983-995. doi:10.1016/j.jchf.2018.06.020More infoThis study prospectively examined physical activity levels and the incidence of heart failure (HF) in 137,303 women, ages 50 to 79 years, and examined a subset of 35,272 women who, it was determined, had HF with preserved ejection fraction (HFpEF) and HF with reduced EF (HFrEF)..The role of physical activity in HF risk among older women is unclear, particularly for incidence of HFpEF or HFrEF..Women were free of HF and reported ability to walk at least 1 block without assistance at baseline. Recreational physical activity was self-reported. The study documented 2,523 cases of total HF, and 451 and 734 cases of HFrEF and HFpEF, respectively, during a mean 14-year follow-up..After controlling for age, race, education, income, smoking, alcohol, hormone therapy, and hysterectomy status, compared with women who reported no physical activity (reference group), inverse associations were observed across incremental tertiles of total physical activity for overall HF (hazard ratio [HR]: Tertile 1 = 0.89, Tertile 2 = 0.74, Tertile 3 = 0.65; trend p < 0.001), HFpEF (HR: 0.93, 0.70, 0.68; p < 0.001), and HFrEF (HR: 0.81, 0.59, 0.68; p = 0.01). Additional controlling for potential mediating factors included attenuated time-varying coronary heart disease (CHD) (nonfatal myocardial infarction, coronary revascularization) diagnosis but did not eliminate the inverse associations. Walking, the most common form of physical activity in older women, was also inversely associated with HF risks (overall: 1.00, 0.98, 0.93, 0.72; p < 0.001; HFpEF: 1.00, 0.98, 0.87, 0.67; p < 0.001; HFrEF: 1.00, 0.75, 0.78, 0.67; p = 0.01). Associations between total physical activity and HF were consistent across subgroups, defined by age, body mass index, diabetes, hypertension, physical function, and CHD diagnosis. Analysis of physical activity as a time-varying exposure yielded findings comparable to those of baseline physical activity..Higher levels of recreational physical activity, including walking, are associated with significantly reduced HF risk in community-dwelling older women.

PloS one, 12(10), e0186296.More infoGenetic variants and traits in metabolic signaling pathways may interact with lifestyle factors such as obesity, physical activity, and exogenous estrogen (E), influencing postmenopausal colorectal cancer (CRC) risk, but these interrelated pathways are not fully understood. In this case-cohort study, we examined 33 single-nucleotide polymorphisms (SNPs) in genes related to insulin-like growth factor-I (IGF-I)/ insulin resistance (IR) traits and signaling pathways, using data from 704 postmenopausal women in Women's Health Initiative Observation ancillary studies. Stratifying by the lifestyle modifiers, we assessed the effects of IGF-I/IR traits (fasting total and free IGF-I, IGF binding protein-3, insulin, glucose, and homeostatic model assessment-insulin resistance) on CRC risk as a mediator or influencing factor. Six SNPs in the INS, IGF-I, and IGFBP3 genes were associated with CRC risk, and those associations differed between non-obese/active and obese/inactive women and between E nonusers and users. Roughly 30% of the cancer risk due to the SNP was mediated by IGF-I/IR traits. Likewise, carriers of 11 SNPs in the IRS1 and AKT1/2 genes (signaling pathway-related genetic variants) had different associations with CRC risk between strata, and the proportion of the SNP-cancer association explained by traits varied from 30% to 50%. Our findings suggest that IGF-I/IR genetic variants interact with obesity, physical activity, and exogenous E, altering postmenopausal CRC risk, through IGF-I/IR traits, but also through different pathways. Unraveling gene-phenotype-lifestyle interactions will provide data on potential genetic targets in clinical trials for cancer prevention and intervention strategies to reduce CRC risk.

Oncology (Williston Park, N.Y.), 31(10), 711-7.More infoExercise is associated with significant reductions in the recurrence and mortality rates of several common cancers. Cancer survivors who exercise can potentially benefit from reduced levels of fatigue, and improved quality of life, physical function, and body composition (ie, healthier ratios of lean body mass to fat mass). The amount of activity required to achieve protective effects is moderate (eg, walking 30 minutes per day at 2.5 miles per hour). However, many healthcare providers report a lack of awareness of the appropriate exercise recommendations across the phases of cancer survivorship, considerations regarding the timing of exercise interventions, and the ability to refer patients to exercise programs specifically aimed at cancer survivors. The American College of Sports Medicine notes that exercise is generally safe for most cancer survivors, and inactivity should be avoided. Their guidelines for exercise call for 150 minutes of moderate or 75 minutes of vigorous aerobic activity per week, and 2 days per week of resistance training (eg, with exercise bands or light weights). Survivors with lymphedema, peripheral neuropathy, breast reconstruction, central lines, and ostomies should follow specific precautions. Providing health professionals with the training and tools needed to provide adequate recommendations to their patients is essential to improving patient outcomes. To facilitate adherence among communities with the greatest need and poor access to services, cultural and environmental adaptations are critical.

Drugs & aging, 32(9), 755-63. doi:10.1007/s40266-015-0298-1More infoAnticholinergic medication use has been associated with several negative health outcomes in older adults, but little is known about its risk for fractures..To examine the association between anticholinergic medication use and fracture outcomes in community-dwelling postmenopausal women..Utilizing a prospective cohort design, we examined data collected from 137,408 women aged 50-79 years from the Women's Health Initiative observational study and clinical trials not reporting hip fracture at baseline. Medications with moderate or strong anticholinergic effects were identified directly from drug containers during in-person interviews. The main outcome was fractures (hip, lower arm/wrist and total fractures). We performed multivariable Cox proportional hazard survival modelling to assess the association between anticholinergic use and the risk of fractures..At baseline, 10.6% of the women were using an anticholinergic medication, of which antihistamines were the most common medication class (48.4%). The multivariable-adjusted hazard ratios for anticholinergic medication use were 1.08 (95% confidence interval [CI] 0.89-1.30) for hip fracture, 1.01 (95% CI 0.91-1.13) for lower arm/wrist fracture and 1.03 (95% CI 0.98-1.09) for total fractures. We observed no association according to subclass or count of anticholinergic medications, or trends between the duration of anticholinergic use and any of the fracture outcomes..Anticholinergic medication use was not associated with an increased risk of fractures among community-dwelling women. Future research should make efforts to capture over-the-counter medication use and the cumulative anticholinergic burden in relation to important health outcomes for older adults.

CURRENT TREATMENT OPTIONS IN ONCOLOGY, 15(1), 14-26.More infoGynecologic cancer patients frequently desire alternative and/or complementary interventions or medicines to aid in relief of both cancer-related and treatment-related side effects. Furthermore, women also seek treatment to aid in superior outcomes and cure rates. Unfortunately, evidence suggests that the use of complementary and/or alternative medicine (CAM) is underreported or not discussed with physicians providing cancer care. In gynecologic cancer literature, there is a lack of scientific evidence either supporting or negating CAM. Because of the lack of information available, health care providers do not have good information regarding safety, efficacy, and dose of CAM. This leads to miscommunication or absence of communication between providers and patients. Because patients do use CAM to improve quality of life (QOL) during and after treatment, it would be educational for providers to know the specific QOL deficits among patients that require attention. Thus, with the ultimate goal of improving QOL for gynecologic cancer patients, providers should be pushed to investigate CAM and determine an honest support or rejection of these therapies.

Journal of Nutrition Education and Behavior, 45(4), S29. doi:10.1016/j.jneb.2013.04.079More infoObjective: To measure change in sugary beverage consumption with nutrition education among low-income 4th and 5th graders. Theory, Prior Research, Rationale: Fifteen percent of US children aged 6 to 11 years are overweight, with an additional 30% at risk. Sugary beverage consumption is linked to obesity and US Dietary Guidelines recommend limiting intake. We hypothesized that nutrition education would result in decreased sugary beverage consumption. Study Design, Setting, Participants, and Intervention: The University of Arizona Nutrition Network (UANN) provides general nutrition education training and materials, aligned with USDA guidelines, to teachers at SNAP-Ed eligible schools. UANN administered self-report behavioral questionnaires to students in 8% of participating 4th and 5th grade classrooms in 5 Arizona counties in both Fall and Spring. Outcome, Measures and Analysis: Descriptive statistics were computed for student demographics and beverage consumption on the prior day. Paired t-tests were used to evaluate change in classroom averages between Fall and Spring. Results: Thirty-three classrooms participated (N1⁄4770 pre, 765 post, 90% complete surveys). Participant characteristics: 71% 4th graders, 50.5% female, 10.1 years of age. Fall sugary beverage consumption was 1.05 ( 0.23) times the previous day; milk and water were consumed 1.58 ( 0.24) and 5.20 ( 0.70) times, respectively. As expected, Arizona springtime beverage consumption increased overall (3.2%). Sugary beverage consumption increased 14.4% and accounted for the greatest portion of the total increase (p1⁄40.006). Small increases in milk (p1⁄40.03) and water (p1⁄40.86) were observed. Conclusions and Implications: This study suggests the need for beverage specific education to shift the children toward more healthful choices. Further research is needed to assess beverage consumption patterns longitudinally, controlling for season. Funding: Supplemental Nutrition Assistance Program Education.

However, few studies have explored potential confounding or effect modification of the association by other factors..We examined the association between height measured at enrollment in 144,701 women participating in the Women's Health Initiative and risk of all cancers combined and cancer at 19 specific sites. Over a median follow-up of 12.0 years, 20,928 incident cancers were identified. We used Cox proportional hazards models to estimate HR and 95% confidence intervals (CI) per 10 cm increase in height, with adjustment for established risk factors. We also examined potential effect modification of the association with all cancer and specific cancers..Height was significantly positively associated with risk of all cancers (HR = 1.13; 95% CI, 1.11-1.16), as well as with cancers of the thyroid, rectum, kidney, endometrium, colorectum, colon, ovary, and breast, and with multiple myeloma and melanoma (range of HRs: 1.13 for breast cancer to 1.29 for multiple myeloma and thyroid cancer). These associations were generally insensitive to adjustment for confounders, and there was little evidence of effect modification..This study confirms the positive association of height with risk of all cancers and a substantial number of cancer sites..Identification of single-nucleotide polymorphisms associated both with height and with increased cancer risk may help elucidate the association.

Anthropometric factors, physical activity, and risk of Non-Hodgkin's lymphoma in the Women's Health Initiative. CANCER EPIDEMIOLOGY, 36(1), 52-59.More infoBackground: Incidence rates of non-Hodgkin's lymphoma (NHL) increased substantially in the United States and worldwide during the latter part of the 20th century, but little is known about its etiology. Obesity is associated with impaired immune function through which it may influence the risk of NHL; other factors reflecting energy homeostasis (height, abdominal adiposity, and physical activity) may also be involved. Methods: We examined the association of anthropometric factors and physical activity with risk of NHL and its major subtypes in a large cohort of women aged 50-79 years old who were enrolled at 40 clinical centers in the United States between 1993 and 1998. Over a mean follow-up period of 11 years, 1123 cases of NHL were identified among 158,975 women. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI). Results: Height at baseline was positively associated with risk of all NHL and with that of diffuse large B-cell lymphoma (HRs(q4vs.q1) 1.19, 95% CI 1.00-1.43 and 1.43, 95% CI 1.01-2.03, respectively). Measures of obesity and abdominal adiposity at baseline were not associated with risk. Hazard ratios for NHL were increased for women in the highest quartile of weight and body mass index at age 18 (HRs(q4vs.q1) 1.29, 95% CI 1.01-1.65 and 1.27, 95% CI 1.01-1.59, respectively). Some measures of recreational physical activity were modestly associated with increased risk of NHL overall, but there were no clear associations with specific subtypes. Conclusion: Our findings regarding anthropometric measures are consistent with those of several previous reports, suggesting that early life influences on growth and immune function may influence the risk of NHL later in life.

Performance evaluation of a multiplex assay for future use in biomarker discovery efforts to predict body composition. CLINICAL CHEMISTRY AND LABORATORY MEDICINE, 49(5), 817-824.More infoBackground: Interest in biomarker patterns and disease has led to the development of immunoassays that evaluate multiple analytes in parallel while using little sample. However, there are no current standards for multiplex configuration, validation, and quality. Thus, validation by platform, population, and question of interest is recommended. We sought to determine the best blood fraction for multiplex evaluation of circulating biomarkers in post-menopausal women, and to explore body composition phenotype discrimination by biomarkers.

Resistance Training Predicts 6-yr Body Composition Change in Postmenopausal Women. Med. Sci. Sports Exerc., Vol. 42, No. 7, pp. 1286-1295, 2010. Purpose: The aim of this study was to examine the association of exercise frequency (ExFreq) and volume (total weight lifted by military press and squats (SQ)) with change in body composition among postmenopausal women participating in a progressive resistance training study. Methods: Previously, sedentary women (n = 122, age = 56.3 + 4.3 yr) were followed for 6 yr. At 6 yr, there were women who had been randomly assigned to resistance training at baseline (n = 65) controls that were permitted to cross over to the exercise program at 1 yr (n = 32) and 25 true controls. Exercisers and crossovers directed to perform eight core exercises for two sets of eight repetitions at 70%-80% of one-repetition maximum, three times weekly, plus progressive weight bearing, stretching, and balance. Body weight and fat were measured at baseline and annually using anthropometry and dual-energy x-ray absorptiometry. Results: Average change in body weight and total body fat were 0.83 +/- 5.39 and 0.64 +/- 4.95 kg at 6 yr, respectively. In multiple linear regression, ExFreq, military press, and SQ were significantly inversely associated with change in body weight (standardized beta coefficient (SBC) = -0.22 to -0.28, P < 0.01), fat (SBC = -0.25 to -0.33, P < 0.01), and trunk fat (SBC = -0.20 to -0.31, P < 0.03) after adjusting for age, years on hormone therapy, change in lean soft tissue, baseline body composition, and baseline habitual exercise. The lowest tertile of SQ (equivalent to 2.5% attendance) demonstrated significant gain in weight, fat, and trunk fat over 6 yr (P < 0.004), whereas the highest tertile SQ (equivalent to 64% attendance) was able to maintain their weight, total, and regional fat. Conclusions: We conclude that resistance training is a viable long-term method to prevent weight gain and deleterious changes in body composition in postmenopausal women.

Lifestyle Modifies the Relationship Between Body Composition and Adrenergic Receptor Genetic Polymorphisms, ADRB2, ADRB3 and ADRA2B: A Secondary Analysis of a Randomized Controlled Trial of Physical Activity Among Postmenopausal Women. BEHAVIOR GENETICS, 40(5), 649-659.More infoGenetic variations in the adrenergic receptor (ADR) have been associated with body composition in cross-sectional studies. Recent findings suggest that ADR variants may also modify body composition response to lifestyle. We assessed the role of ADR variants in body composition response to 12 months of resistance training versus control in previously sedentary postmenopausal women. Randomized trial completers were genotyped for A2B (Glu9/12) by fragment length analysis, and B2 (Gln27Glu) and B3 (Trp64Arg) by TaqMan (n = 148, 54% hormone therapy users). Associations between genotypes and body composition, by dual energy X-ray absorptiometry, were analyzed using univariate models. There was no main effect of individual genes on change in body composition, however, gene x exercise interactions were observed for A2B (Glu9/12) and B2 (Gln27Glu) on change in lean soft tissue (LST, p = 0.02); exercisers on the A2B (Glu9-) background gained LST compared to a loss among controls over 12 months (p < 0.05), with no significant intervention effect on the A2B (Glu9+) background. Similarly, there was a significant LST gain with exercise on the B2 (Glu27+) background compared to loss among controls and no intervention effect on the B2 (Glu27-) background. A non-significant association between total body fat (TBF) and B3 (Trp64Arg) persisted among sedentary controls only when intervention groups were separated (%TBF gain with B3 (Arg64+) carriage, p = 0.03); exercisers lost TBF regardless of genotype. In summary, effect modification by lifestyle was demonstrated on ADRA2B, B2, and B3 genetic backgrounds. Individuals with certain ADR genotypes may be more vulnerable to adverse changes in body composition with sedentary behavior, thus these candidate genes warrant further study.

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.

Changes in Body Weight and Metabolic Indexes in Overweight Breast Cancer Survivors Enrolled in a Randomized Trial of Low-Fat vs. Reduced Carbohydrate Diets. NUTRITION AND CANCER-AN INTERNATIONAL JOURNAL, 62(8), 1142-1152.More 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 76g/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.

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. This preliminary analysis indicates that markers of metabolic syndrome can be improved by diet in breast cancer survivors, but there is a trend toward loss of lean mass accompanying loss of fat. >Variable Change; p-value >Weight (kg) -8.46 ± 4.08; BMI (kg/m2) -3.05 ± 1.6; %Total Body Fat -4.8 ± 3.0; Trunk Fat (kg) -3.4 ± 1.8; Lean Mass (kg) -0.86 ± 1.6; 0.06 >Fasting Plasma Glucose (mg/dl) -3.00 ± 8.99; 0.18 >2hr-Post-Load Glucose (mg/dl) 8.70 ± 28.39; 0.36 >Fasting Insulin (uU/ml) -3.56 ± 5.83; 0.02 >Glycosylated Hemoglobin (%) -0.17 ± 0.34; 0.05 >Total Cholesterol (mg/dl) -8.61 ± 29.95; 0.24 >Triglycerides (mg/dl) 0.06 ± 77.26; 1.0 >High-density lipoprotein cholesterol (mg/dl) 1.56 ± 9.08; 0.48
