【Abstract】

Using data collected from seven national follow-up surveys between 1998 and 2014 and a group-based trajectory model, this paper investigated ADL disability trajectories and mortality probability trajectories among the oldest old at the same time. We attempted to explain the membership in disability trajectory groups from three aspects, namely, demographic, socioeconomic and childhood characteristics. The analysis results showed that disability trajectories among the oldest old were heterogeneous. There were three trajectory groups for men, namely, one starting with a low level of disability that gradually progressed, one starting with a low level of disability that quickly progressed, and one starting with a high level of disability that gradually progressed. And there were three trajectory groups for women, too, namely, one starting with a low level of disability that gradually progressed, one starting with a low level of disability that quickly progressed, and one starting with a high level of disability that quickly progressed. Different groups of disability trajectories and mortality trajectories followed the same hierarchical distribution. Women’s mortality rate was often lower than men’s when they belonged to the same disability trajectory group. The residence location and the occupation affected the oldest old’ membership in disability trajectory groups.
