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.
针对三项老年流行病学研究既定人群（EPESE）随访的头三年中的死亡率，研究了其与参与者自我报告的功能能力之间的关系。在马萨诸塞州的东波士顿（N = 3812）、爱荷华州的爱荷华县和华盛顿县（N = 3673）以及康涅狄格州的纽黑文（N = 2812），65岁及以上的非机构化人员被问及一系列问题以确定其功能状态。这些指标用于死亡率数据的逻辑回归分析，结果显示，报告的残疾数量增加显著增加了死亡风险，这一风险超出了参与者年龄和性别的影响，或各研究地点之间的方法差异。总体活动能力方面的残疾（例如，行走半英里、爬楼梯或在家中进行繁重工作的能力）与死亡率的关联比日常生活活动指标更强。
