OBJECTIVES The purpose of these analyses was to test the hypothesis that depressive symptomatology affects the risk of onset of physical disability in high-functioning elderly adults. METHODS The data come from the MacArthur Study of Successful Aging, a community-based cohort of high-functioning adults aged 70 through 79 years who were assessed twice at a(More)
The factors associated with driving cessation, number of miles driven, and changes in mileage were assessed in a community-living elderly population. A driving survey was administered in 1989 to surviving members of the New Haven EPESE cohort. Of 1,331 respondents, 456 had driven and 139 had stopped driving between 1983 and 1989. Independent predictors of(More)
OBJECTIVES To determine whether elevated serum cholesterol level is associated with all-cause mortality, mortality from coronary heart disease, or hospitalization for acute myocardial infarction and unstable angina in persons older than 70 years. Also, to evaluate the association between low levels of high-density lipoprotein cholesterol (HDL-C) and(More)
Data from a cohort of relatively high functioning, older men and women were used to test the hypothesis that stronger self-efficacy beliefs predict better maintenance of cognitive performance. Structural equation modeling revealed that stronger baseline instrumental efficacy beliefs predicted better verbal memory performance at follow-up among men but not(More)
This is the first study to focus on Medicare mammography rescreening using a relatively large population of older women over a long followup period. To assess correlates of regular mammography, we followed all women age 65 or over enrolled continuously in Medicare fee-for-service (FFS) (n = 515,746) over a 7-year period. Data were drawn from the CMS claims(More)
BACKGROUND Gender differences in functioning among older adults have been well documented. Differential reporting of functional problems by men and women may contribute to this observed difference. The purpose of this study was to examine the gender differences in functional ability by comparing self-reported function to observed performance of physical(More)
INTRODUCTION we have tested the hypothesis that the co-occurrence of common impairments (motor and cognitive impairments, vision and hearing loss, depressive symptoms) of later life have exacerbating effects on disability [activities and instrumental activities of daily living, social and role function, (in)activity]. METHOD data were drawn from a(More)
PRIMARY OBJECTIVE Health surveys, especially those for older persons, include numerous detailed items about disability. There has been little effort to develop a global disability item, that is, one question that covers the concept of disability briefly but well. This article discusses how parsimony can be achieved through a single item, or less desirably(More)
