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

Abstract

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. 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. 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. 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.
