BACKGROUND: Although discrimination has been identified as a potential determinant of existing racial/ethnic health disparities, no studies have investigated whether racial discrimination contributes to disparities in physical activity. PURPOSE: The primary aim of the current study was to examine the association between interpersonal racial discrimination and physical activity. METHODS: Baseline data were collected during 2004-2005 among a predominately black and Hispanic sample of adult residents living in 12 low-income-housing sites in Boston MA (n=1055). Residents reported experiences of lifetime racial discrimination during interviewer-administered surveys and wore a pedometer for 5 days to measure physical activity. For analyses, performed in 2009, linear regression models with a cluster design were conducted to predict physical activity, measured as steps per day. RESULTS: Nearly 48% of participants reported ever experiencing racial discrimination, and discrimination was most commonly experienced on the street or in a public setting. No association was found between discrimination and physical activity, when examined in bivariate, multivariable, or race-stratified models. CONCLUSIONS: The current results indicate that self-reported racial discrimination is not a key determinant of physical activity among residents living in low-income housing. However, additional research is warranted to address current limitations of this study.
