Mortality and physical functioning in epidemiologic studies of three older populations.
Mortality experienced in the first three years of follow-up for three Established Populations for Epidemiologic Studies of the Elderly (EPESE) is examined in relation to the participants' self-reported functional ability. In East Boston, Massachusetts (N = 3,812), Iowa and Washington Counties, Iowa (N = 3,673), and New Haven, Connecticut (N = 2,812), noninstitutionalized persons aged 65 and older were asked a series of questions to determine their functional status. These measures, used in logistic regression analyses of the mortality data, showed that an increased number of reported disabilities significantly increased the risk of mortality over and above the effects of the age and sex of the participant, or the methodological differences among the sites. Disabilities in gross mobility (e.g., ability to walk a half mile, climb stairs, or perform heavy work around the house) were more strongly related to mortality than were measures of activities of daily living.
