PURPOSE 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. METHODS 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(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)
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)
OBJECTIVES To date, methodologies are lacking that address a holistic assessment of wellness in older adults. Technology applications may provide a platform for such an assessment, but have not been validated. We set out to demonstrate whether e-health applications could support the assessment of older adults' wellness in community-dwelling older adults. (More)
PURPOSE The aim of this paper is to demonstrate how informatics applications can support the assessment and visualization of older adults' wellness. A theoretical framework is presented that informs the design of a technology enhanced screening platform for wellness. We highlight an ongoing pilot demonstration in an assisted living facility where a(More)
BACKGROUND To develop a positive aging phenotype, we undertook analyses to describe multiple dimensions of positive aging and their relationships to one another in women 65 years of age and older and evaluate the performance of individual indicators and composite factors of this phenotype as predictors of time to death, years of healthy living, and years of(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)
PURPOSE Some studies suggest that anthropometric measures of abdominal obesity may be superior to body mass index (BMI) for the prediction of cardiometabolic risk factors; however, most studies have been cross-sectional. Our aim was to prospectively examine the association of change in BMI, waist-to-hip ratio (WHR), waist circumference (WC), and waist(More)
OBJECTIVES To compare the ability of the commonly used Women's Health Initiative (WHI) and Cardiovascular Health Study (CHS) frailty phenotypes to predict falls, hip fracture, and death in WHI Clinical Trial participants aged 65 and older. DESIGN Longitudinal cohort study. SETTING WHI Clinical Trial. PARTICIPANTS Participants with data for WHI and CHS(More)
OBJECTIVES/BACKGROUND We assessed prevalence and correlates of insomnia; associations between changes in insomnia with incidence of physical, emotional, and mixed impairments (PI, EI, and MI, respectively); and age as a moderator in these relationships. PARTICIPANTS/METHODS The Women's Health Initiative (WHI) clinical trial (CT) and observational study(More)
