Abstract Background The development of disability related to activities of daily living (ADL) is of great concern in the aging population, particularly for Hispanic and Non-Hispanic (NH) Black older adults, where disability prevalence is greater compared to NH Whites. ADL-disability is typically measured across many functional tasks without differentiating upper- versus lower-limb limitations, hindering our understanding of disability burden. Despite the importance of the upper limbs for completing ADL and known age-related declines in function, racial/ethnic differences in upper limb function remain largely unknown. Methods We identified 4 292 NH White, NH Black, and Mexican American older adults (≥65) from the 2011–2018 waves of the National Health and Nutrition Examination Survey (NHANES). We classified participants as having a limitation based on their ability to complete 5 upper-limb tasks (preparing meals, eating, dressing, reaching overhead, and grasping small objects) and compared limitation rates across racial/ethnic groups. Results Compared to NH Whites, NH Black older adults had significantly greater odds of reporting difficulties preparing meals (odds ratio OR: 1.36, 95% confidence interval 95% CI: 1.01, 1.86) and dressing (OR: 1.55, 95% CI: 1.19, 2.02), while Mexican Americans had greater difficulty preparing meals (OR: 1.70, 95% CI: 1.12, 2.58), dressing (OR: 1.63, 95% CI: 1.12, 2.36), and grasping small objects (OR: 1.48, 95% CI: 1.06, 2.07). Conclusions Our results demonstrate differences in self-reported upper limb ADL-disability across racial/ethnic groups, particularly for Mexican American older adults. Such findings underscore the need for routine monitoring of upper limb function throughout adulthood to identify limitations and target therapeutic interventions before independence is compromised.
