Associations between social determinants of health and 10-year change in everyday functioning within Black/African American and White older adults enrolled in ACTIVE.

Introduction: Given prior work showing racial differences on baseline social determinants of health (SDoH) and 10-year trajectories of everyday functioning, we examined associations between SDoH and longitudinal everyday functioning performance in Black/African American and White older adults. Methods: Participants were 2505 older adults (Mage = 73.5; 28% Black/African American) without dementia. SDoH included economic stability/status, education access/quality, health-care access, neighborhood/built environment, and social/community contexts. The Observed Tasks of Daily Living (OTDL) measured everyday functioning and was administered at baseline and 1-, 2-, 3-, 5-, and 10-year visits. Results: Across the sample, social and community context and economic stability/status were associated with steeper age-related OTDL declines (ßs = 0.05 to 0.07, Ps < 0.001). Lower levels of social and community context (ß = 0.08, P = 0.002) and economic stability/status (ß = 0.07, P = 0.04) were associated with OTDL linear age declines in Black/African American participants, but not in White participants (Ps > 0.30). Discussion: Inequities across SDoH accelerate age-related declines in everyday functioning among Black/African American older adults.
