One potential mechanism by which physical activity may protect against breast cancer is by decreasing mammographic density. Percent mammographic density, the proportion of dense breast tissue area to total breast area, declines with age and is a strong risk factor…
OBJECTIVE: To evaluate whether adolescent obesity is associated with difficulties in becoming pregnant later in life. DESIGN: Cross-sectional analysis of baseline data from a longitudinal cohort. SETTING: Multiethnic, community-based observational study of U.S. women. PATIENT(S): Three thousand one hundred fifty-four…

OBJECTIVES: This prospective study examined whether changes in traditional and novel coronary heart disease (CHD) risk factors are greater within a year of the final menstrual period (FMP), relative to changes that occur before or after that interval, in a…
INTRODUCTION: The burden of erectile dysfunction (ED) among different racial and ethnic groups is unclear, in part, because prior studies have not included all four major racial and ethnic groups in the same population-based sample. AIM: To determine the prevalence…
BACKGROUND: Dietary glycemic load (GL) and glycemic index (GI), indicators of the postprandial glucose and insulin response to carbohydrate composition of diet, have been suggested as independent risk factors for cardiovascular disease and diabetes. However, current knowledge about the distribution,…

METHODS: Year-20 data from the Coronary Artery Risk Development in…
Although most women report vasomotor symptoms (hot flashes, night sweats) during midlife, their etiology and risk factors are incompletely understood. Body fat is positively associated with vasomotor symptoms cross-sectionally, but the longitudinal relation between changes in body fat and vasomotor…
BACKGROUND: Numerous modifiable factors have been associated with a reduced risk of colorectal cancer, including the chronic use of NSAIDs. Thus, it is biologically plausible that HMG-CoA reductase inhibitors (statins), therapeutic agents that also possess anti-inflammatory effects, are also associated…

Few studies have prospectively examined lipid changes across the menopause transition or in relation to menopausal changes in endogenous hormones. The relative independent contributions of menopause and age to lipid changes are unclear. Lipid changes were examined in relation to…
High percent mammographic breast density is strongly associated with increased breast cancer risk. Though body mass index (BMI) is positively associated with risk of postmenopausal breast cancer, BMI is negatively associated with percent breast density in cross-sectional studies. Few longitudinal…

BACKGROUND: This study was done to determine whether physical activity at baseline is independently associated with musculoskeletal pain and fulfilling one's physical role over 3 subsequent years. METHODS: Our research involved a 3-year longitudinal study of over 2400 community-dwelling, midlife…
BACKGROUND: Although walking is the most popular leisure-time activity for adults, few long-term, longitudinal studies have examined the association between walking, an affordable and accessible form of physical activity, and weight gain. OBJECTIVE: The objective was to evaluate the association…
BACKGROUND: Diabetes disproportionately affects Latinos. However, examining Latinos as one group obscures important intra-group differences. This study examined how generational status, duration of US residence, and language preference are associated with diabetes prevalence and to what extent these explain the…
Many epidemiologic studies include symptom checklists assessing recall of symptoms over a specified time period. Little research exists regarding the congruence of short-term symptom recall with daily self-reporting. The authors assessed the sensitivity and specificity of retrospective reporting of vasomotor…

We assessed medical, sociodemographic, behavioral, and psychosocial predictors of overall gestational weight gain, as well as gains below, within, or above the range recommended by the Institute of…
OBJECTIVE: Studies in predominantly non-Hispanic white populations have suggested that physical activity during pregnancy is associated with a reduced risk of gestational diabetes mellitus (GDM). There are few such studies in Hispanic women, a group at increased risk for GDM…
BACKGROUND: Body mass index (BMI) is directly related to testosterone (total T and free T) and inversely to SHBG cross-sectionally, but little is known about how changes in body fat and androgen markers affect each other over time. METHODS: Participants…

PURPOSE: Physical activity (PA) is one of few modifiable breast cancer risk factors. There have been few studies of the relation between PA and mammographic density, especially in multiethnic populations. METHODS: In a cohort of pre- and early perimenopausal women…
It has long been hypothesized that increased adiposity would be associated with decreased vasomotor symptoms during menopause because of conversion of androgens to estrogens in body fat. However, recent thermoregulatory models have postulated that increased adipose tissue would be associated…
BACKGROUND: Cost-effective interventions to improve diet and physical activity are a public health priority. Alive! is an email-based intervention to increase physical activity, reduce saturated and trans fats and added sugars, and increase fruit and vegetable consumption. It was shown…

PATIENTS AND METHODS: A prospective study was performed of 1,490 women diagnosed and treated for early-stage breast cancer…
AIMS: We sought to determine if the frequency of reported physical or emotional premenstrual symptoms (PMSx) was associated with (1) dietary intake of phytoestrogens, fiber, fat, or calcium, (2) consumption of alcohol or caffeine, (3) active or passive smoke exposure…
OBJECTIVE: The association between physical activity or cardiovascular fitness and chronic disease risk in men might be mediated, in part, through androgens. Limited data exists on the potential associations of activity or fitness with serum hormones. We examined the associations…
BACKGROUND: By one estimate, 60% of women experiencing the menopause transition perceive that they have memory problems, but most studies that have used cognitive function tests have not substantiated a relation between menopause stage and cognitive performance. We sought to…
PURPOSE: To examine whether weight gain after diagnosis of breast cancer affects the risk of breast cancer recurrence. PATIENT AND METHODS: Patients included 3215 women diagnosed with early stage breast cancer (Stage I >1 cm., II, and IIIA) who were…

PURPOSE: Hormonal changes associated with menopause, chronological aging, and lifestyle, specifically physical activity, may all influence the changes in body composition and fat distribution experienced by midlife women. This cross-sectional study examined those relations in a representative sample of 248…
The Life After Cancer Epidemiology (LACE) Study, a cohort of 2321 early stage breast cancer survivors, was established in 2000 to examine how modifiable behavioral risk factors affect quality of life and long-term survival. Women were recruited primarily from the…
PURPOSE: Autonomic nervous system function may be a mechanism by which frequent physical activity is associated with better coronary heart disease outcomes. In a diverse, population-based sample, we tested whether physical activity participation was associated with higher parasympathetic function. METHODS:…
BACKGROUND: Overall rates of obesity have increased dramatically in the United States, yet African American women remain disproportionately represented among the overweight and obese. The excess weight observed in African American women is primarily considered a result of low socioeconomic…
OBJECTIVE: Women beginning the transition to menopause now have access to complementary and alternative therapies (CAM) that were not universally available in the past. Little is known about the association between CAM use and the use of conventional health care…
OBJECTIVE: To prospectively evaluate whether childbearing leads to development of overweight in women and to evaluate the role of other known risk factors. RESEARCH METHODS AND PROCEDURES: A prospective, multicenter observational study, the Coronary Artery Risk Development in Young Adults…
