<p><b>PURPOSE: </b>This research combined cross-sectional and longitudinal data to characterize age-related trajectories in physical disability for adults with and without diabetes in the United States and to investigate if those patterns differ by age, gender, race or ethnicity, and education.</p><p><b>DESIGN AND METHODS: </b>Data were examined on 20,433 adults aged 51 and older from the 1998 to 2006 Health and Retirement Study. Multilevel models and a cohort-sequential design were applied to quantitatively depict the age norm of physical disability after age 50.</p><p><b>RESULTS: </b>Adults with diabetes not only experience greater levels of physical disability but also faster rates of deterioration over time. This pattern is net of attrition, time-invariant sociodemographic factors, and time-varying chronic disease conditions. Differences in physical disability between adults with and without diabetes were more pronounced in women, non-White, and those of lower education. The moderating effects of gender and education remained robust even after controlling for selected covariates in the model.</p><p><b>IMPLICATIONS: </b>This study highlighted the consistently greater development of disability over time in adults with diabetes and particularly in those who are women, non-White, or adults of lower education. Future studies are recommended to examine the mechanisms underlying the differential effects of diabetes on physical disability by gender and education.</p>
