ABSTRACT
BACKGROUND: Experiencing racial discrimination may be associated with poor health outcomes including negative emotional states and substance use. The workplace is a setting where people may experience discriminatory treatment. Objectives: This study examined associations, between negative emotions due to treatment based on race (NE), workplace racial discrimination (WRD), and substance use outcomes (drinking and smoking), stratified by race. Methods: Data from the cross-sectional 2014 Behavioral Risk Factor Surveillance System (BRFSS), Minnesota and New Mexico sub-samples, were analyzed. This study excluded non-Hispanic white participants, resulting in a sample of n = 3098 adult, U.S. residents. Multivariable logistic regression models were utilized to examine the associations, and possible interactions, between WRD, NE, and substance use (alcohol and tobacco). Results: Prior to stratification, WRD was not associated with drinking or smoking after controlling for NE and other sociodemographic variables, however, NE was associated with heavy drinking. NE appeared to account for some of the observed bivariate associations between WRD and heavy drinking and daily smoking. Post-stratification, WRD was associated with heavy drinking for non-Hispanic other respondents, even after controlling for NE. For non-Hispanic black participants, NE was associated with smoking after controlling for WRD. A stratified interaction analysis of WRD*NE revealed that there was only an association between NE and heavy drinking for Hispanic participants who did not experience WRD. Conclusions: The relationship between WRD and substance use may be in part accounted for by NE. Further exploration is needed to more fully understand why associations exist for some race/ethnicity groups but not others.
