Abstract

Objectives: In this study, we examined how racial discrimination and neighborhood perceptions relate to physical activity and sedentary behavior mediated through depression symptoms. Methods: Data were from the first year of a longitudinal cohort study, Project Creating a Higher Understanding of cancer Research and Community Health (CHURCH), based on a convenience community sample of church-attending African Americans collected between April 2012 and March 2013 (N = 370) in Houston, Texas. Measures included racial discrimination, perceived neighborhood problems and vigilance, depression (CES-D), physical activity (IPAQ-short), and sedentary behavior. Results: Main effects from the structural equation model showed that racial discrimination (b =.20, p <.01) was related to greater depression symptoms. The same pattern emerged for neighborhood problems, but the effect was not significant (b =.20, p =.07). Further, depression symptoms were related to less physical activity (b = -.62, p =.03) and greater sedentary behavior (b =.64, p <.01). Indirect effects showed that depression mediated the relationship between racial discrimination and neighborhood problems on physical activity and sedentary behavior. Conclusions: Depression symptoms are an important mechanism by which racial discrimination and perceived neighborhood problems impact physical activity and sedentary behavior.
