背景：虽然有证据表明日本人口的健康预期有所改善，但现有的估计是基于横断面调查数据中的发病率。Objectives：本研究采用了一种多状态寿命表方法来计算1990年至2009年两个纵向调查队列的基于发病率的健康预期指标，即活动和非活动预期寿命（LE）。日本老年人全国调查（1990-1999）和日本大学日本老龄化纵向研究（1999-2009）。我们采用插值马尔可夫链技术来计算的年数在65岁的花费和没有困难的日常生活活动（ADLs）或仪器ADLs.Results：我们记录了显着增加活跃LE男性和女性在65岁以上的10年的研究期间。有显着的变化，在总LE的男子和妇女的积极生活的百分比。不活跃LE没有显着改变在两个调查cohort在study period.Conclusions：我们的研究结果表明，在日本的老年人的健康状况在很大程度上改善了10年的研究期间，在两个生命的持续时间和时间在活跃的状态。这一发现提供了日本老年男女发病率压缩的证据。
Background:Although there is evidence of improvements in health expectancy among the Japanese population, existing estimates are based on the prevalence of morbidity taken from cross-sectional survey data.Objectives:This study employed a multistate life table approach to compute incidence-based health expectancy measures, namely active and inactive life expectancy (LE), for two longitudinal survey cohorts from 1990 to 2009.Methods:This study used data from two longitudinal surveys of older adults in Japan: the National Survey of the Japanese Elderly (1990–1999) and the Nihon University Japanese Longitudinal Study of Aging (1999–2009). We employed the Interpolation of Markov Chains technique to compute the number of years at age 65 years to be spent with and without difficulty in performing activities of daily living (ADLs) or instrumental ADLs.Results:We documented significant increases in active LE for men and women at age 65 years over the 10-year study period. There were significant changes in total LE for men and in the percentage of active life for women. Inactive LE did not significantly change across the two survey cohorts during the study period.Conclusions:Our results show that the health status of older adults in Japan has largely improved over the 10-year study period, with increases in both the duration of life and time spent in an active state. This finding offers evidence of compression of morbidity among older men and women in Japan.
