Social engagement and its links to cognition differ across non-Hispanic Black and White older adults.

Racial inequalities in dementia have been linked to disparities in socioeconomic status, chronic diseases, and psychosocial stress. Less focus has been given to psychosocial protective factors. Previous studies suggest that social engagement promotes better cognitive aging, but few have examined whether social engagement or its associations with cognition vary across non-Hispanic Whites (NHW) and Blacks (NHB).
