BACKGROUND Although self-rated health (SRH) and performance-based physical function (PPF) are both strong predictors of mortality, little research has investigated the relationships between them. The objective of this study was to evaluate longitudinal, bi-directional associations between SRH and PPF. METHODS We evaluated longitudinal associations between(More)
BACKGROUND The associations of coffee and caffeine intakes with the risk of incident hypertension remain controversial. OBJECTIVE We sought to assess longitudinal relations of caffeinated coffee, decaffeinated coffee, and total caffeine intakes with mean blood pressure and incident hypertension in postmenopausal women in the Women's Health Initiative(More)
PURPOSE Distress and reduced quality of life (QOL) are common among people with cancer. No study has compared these variables after breast cancer diagnosis to pre-cancer diagnosis levels. METHODS Data on women with breast cancer 50 years of age or older (n = 6949) were analyzed from the Women's Health Initiative (1993-2013). Health-related QOL (physical(More)
In the present study, we aimed to examine the total and moderating effects of needs-satisfaction-driven quality-of-life (QoL) measure on age-related change in functional status. Participants in the Survey of Health and Retirement in Europe (N = 18,781 at Wave 1) completed a measure of QoL (CASP-12) at baseline and reported their functional status across(More)
PURPOSE OF THE STUDY To examine whether Veteran status influences (a) women's survival to age 80 years without disease and disability and (b) indicators of successful, effective, and optimal aging at ages 80 years and older. DESIGN AND METHODS The Women's Health Initiative (WHI) enrolled 161,808 postmenopausal women aged 50-79 years from 1993 to 1998. We(More)
BACKGROUND/OBJECTIVES The relationship between obesity and circulating levels of antioxidants is poorly understood. Most studies that have examined the association of adiposity with blood or tissue concentrations of antioxidant micronutrients have been cross-sectional, and few have compared the associations for indices of overall obesity and central(More)
BACKGROUND Independent predictors of preserved cognitive functioning and factors associated with maintaining high preserved cognitive function in women ≥ 80 years remain elusive. METHODS Two thousand two hundred twenty-eight women with a mean age of 85 years who participated in the Women's Health Initiative Memory Study were classified as cognitively(More)
BACKGROUND Aspects of eudaimonic well-being, such as personal growth (PG) and purpose in life (PL), have been highlighted as important to older adults' health. We investigated the relationship of PG and PL with patterns of survival to the age of 85 years and older. METHODS The sample included 8,880 women from the Women's Health Initiative cohort who(More)
Frailty is an emerging geriatric syndrome that refers to a state of increased vulnerability to adverse events including mortality, morbidity, disability, hospitalization, and nursing home admission. Despite its long conceptual and operational history in research and publications, frailty and mechanisms of frailty development are still poorly understood. In(More)
OBJECTIVES To identify potentially modifiable factors associated with overall and poor-quality-of-life (QoL) survival in physically frail older women. DESIGN Prospective study with 7 years of follow-up to examine mortality and, in survivors with a QoL measurement within the next 3 years, to examine poor- versus good-QoL patterns of survival.
