Determinants of stability and changes in self-reported work disability among older working-age populations

Data from the Health and Retirement Study, 1992-1994, were used to analyze (1) the prevalence and incidence of self-reported work disability among older working-age populations over a two-year period, and (2) the effect of the stability/changes in physical and functional health conditions, controlling for socioeconomic and occupational characteristics, on the stability/changes in self-reported work ability/disability. Findings show a high rate of transitions into and out of work-disabled status over the two-year period. Findings also show that, although objective physical and functional health problems and low self-ratings of health at wave 1 were significant determinants of self-reported work disability at wave 1, most subsequent changes in objective physical and functional health conditions over the two-year period were not significantly associated with the changes in self-report of work disability between wave 1 and wave 2. Especially, improved health conditions were not significantly associated with regained work ability between the two waves. Of the demographic variables, female gender significantly increased the likelihood of reporting work disability at wave 2, and being Black or Hispanic significantly decreased the likelihood of reporting regained work ability at wave 2. Research and policy implications of the findings are discussed.
