| Annotation | To understand decline in chronic disability prevalence in the older population in the US, the authors compared active-life expectancy and life expectancy using the six National Long-Term Care Surveys carried out 1982 to 2004 and linked to continuous time Medicare service data for grade of membership for the same period. They simultaneously estimated continuous-time disability dynamic and mortality functions to calculate life tables for specific disability states and for temporally changing mixtures of disability states. Disability dynamics measured as changes to grade of membership scores showed significant variation across two birth cohorts followed for 24 years. Disability dynamics and disability-specific hazard functions were significantly improved in the younger cohort (those aged 65-74 in 1982). These results, supporting the hypothesis of morbidity compression, indicate that younger cohorts of older people are living longer in better health. The methods describe individual disability transitions and mortality and other factors associated with disability changes, making it possible to better evaluate interventions to promote future declines in disability.
