这项研究阐明了死亡率和残疾相互作用的过程，以确定美国70岁及以上人口按年龄、性别、种族和教育程度划分的活跃预期寿命差异。分析使用的数据从老龄化的纵向研究和多状态寿命表构建的风险模型的结果。在每个年龄段，妇女从事活动和不从事活动的年数都比男子多;然而，妇女一生中从事活动的时间所占比例较小。这些差异主要是由于死亡率的差异有利于妇女。与高中以上教育程度的人相比，高中以下教育程度的人的总预期寿命和活跃预期寿命较短，但非活跃预期寿命相似。有没有显着的种族差异，总寿命的种族教育组的老年人口，但黑人有较低的预期活跃的生活比非黑人，因为更差的功能。
This study clarifies the process by which mortality and disability interact to determine differences in active life expectancy by age, sex, race, and education for the U.S. population 70 years of age and over. The analysis is performed using data from the Longitudinal Study of Aging and multistate life tables constructed using the results of hazard models. Women spend more years than men both active and inactive at every age; however, the proportion of life that is expected to be active is smaller for women. These differences are largely due to mortality differences favoring women. Persons with less than a high school education have shorter total and active life expectancies but similar expected lengths of inactive life compared to those with more than a high school education. There are no significant race differences in total life expectancy for race-education groups of the older population; but Blacks have lower expected active life than non-Blacks because of worse functioning.
