Abstract

Objective-Summary measures of population health are statistics that combine mortality and morbidity to represent overall population health in a single index. Such measures include healthy life expectancy, also called disability-free life expectancy and active life expectancy. Healthy life expectancy can be calculated using cross-sectional or longitudinal survey data. This report presents a comprehensive discussion of a method for calculating healthy life expectancy using data from longitudinal surveys. Methods-Healthy life expectancies are calculated using the multistate life table model. Expected life in various states of health is estimated using data from the Second Longitudinal Study of Aging and the Medicare Current Beneficiary Survey to illustrate the calculation of the statistics and the discussion of data and methodology related issues. Results-The study shows that estimating summary measures of population health using longitudinal survey data provides the opportunity of using incidence rather than prevalence rates. Health measures estimated based on incidence reflect the most recent health status of the population. Models that use longitudinal survey data measure transitions from good to poor health as well as poor to good health. That is, the models account for recovery from morbidity or illness. Longitudinal survey data canalsobeusedtocalculate healthy or active life expectancies by initial health states.

利用纵向调查数据估计健康预期寿命:人口健康措施的方法和技术。
目的:人口健康的汇总指标是将死亡率和发病率结合在一起,以单一指数表示总体人口健康的统计数据。这些措施包括健康预期寿命,也称为无残疾预期寿命和积极预期寿命。健康预期寿命可以使用横断面或纵向调查数据来计算。本报告全面讨论了一种利用纵向调查数据计算健康预期寿命的方法。方法—使用多状态生命表模型计算健康预期寿命。不同健康状态下的预期寿命估计使用来自第二次老龄化纵向研究和医疗保险当前受益人调查的数据来说明统计数据的计算和数据和方法相关问题的讨论。结果:研究表明,使用纵向调查数据估计人口健康的综合措施提供了使用发病率而不是患病率的机会。根据发病率估计的保健措施反映了人口最近的健康状况。使用纵向调查数据的模型衡量从健康状况良好到健康状况不佳以及从健康状况不佳到健康状况良好的转变。也就是说,这些模型考虑了从发病或疾病中恢复的情况。纵向调查数据可用于根据初始健康状态计算健康或积极的预期寿命。
