| Annotation | There is no clear consensus about how a person's sex influences prevalent disability and through what mechanisms. It was investigated whether sex had a direct independent effect on disability, or an interactive effect on the relationship between chronic diseases/conditions and disability; and whether these effects differed in middle-aged versus older adults. Baseline data was drawn from two nationally representative US health interview surveys, the Health and Retirement Study (HRS) and the Study of Asset and Health Dynamics Among the Oldest Old (AHEAD), and disability and covariate measures that were nearly identical in both surveys. Models demonstrated no direct sex effect for activities of daily living (ADL) disability in either age group, after adjusting for key covariates. The implication is drawn that the effect of sex on ADL difficulty is largely explained by social and health-related covariates in middle aged and older adults. In contrast, the independent association of female sex with decreased strength and mobility in both groups cannot be explained by the models' social or health-related variables. Additionally the positive association of body mass index (BMI) with mobility difficulty is significantly worse for women than for men. (KJ/RH). |
