Everyday Discrimination, Neighborhood Perceptions, and Incidence of Activity Limitations Among Middle-Aged and Older African Americans.

OBJECTIVES: This study aims to examine the relationship between everyday discrimination, neighborhood perceptions, and the incidence of daily activity limitations (i.e., activities of daily living [ADL] and instrumental activities of daily living [IADL]) among middle-aged and older African Americans. This study also examines whether neighborhood perceptions moderate the association between discrimination and the incidence of daily activity limitations.

METHODS: Data were from the 2006 to 2016 waves of the Health and Retirement Study. African Americans aged 50 or older free of ADL limitations (N = 1,934) and IADL limitations (N = 2,007) at baseline were selected. Cox proportional hazards regression models were performed to test the study aims. Multiple imputations were applied to handle missing data.

RESULTS: One-unit increase in everyday discrimination was associated with a 25% (p < .05) higher risk of ADL limitation onset. Perceived neighborhood social cohesion and physical disadvantage moderated the association between discrimination and IADL limitation onset.

DISCUSSION: Everyday discrimination represents a significant stressor that negatively affects older African Americans' performance of daily activities. Community-level efforts that improve neighborhood perceptions are needed to alleviate the negative effects of discrimination on the incidence of activity limitations.
