Abstract

Introduction: Racial/ethnic discrimination (hereafter, discrimination) is associated with tobacco use. However, little is known about the relationship between discrimination and dual/polytobacco use and tobacco use disorder (TUD), including how these relationships vary by race/ethnicity. Methods: Data on adults 18 and older come from the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (n = 35,881). Past-year discrimination was measured using the Experiences of Discrimination scale. Past 30-day exclusive, dual, and polytobacco use was measured as the mutually exclusive use of any combination of four types of tobacco products: cigarettes, electronic nicotine delivery systems, other combustibles (i.e., cigars and pipe), and smokeless tobacco. Past-year TUD was defined according to DSM-5 criteria. Associations between discrimination and exclusive, dual, and polytobacco use and discrimination and TUD were estimated using multinomial logistic regression and logistic regression, respectively. Models were stratified by race/ethnicity (i.e., Hispanic, non-Hispanic (NH) White, NH Black, another race/ethnicity) to assess effect modification. Results: Adults who used tobacco and who had TUD was 24.2% and 19.2%, respectively. More discrimination was associated with higher odds of exclusive, dual, and polytobacco use as well as TUD. Models stratified by race/ethnicity suggest that discrimination was associated with dual/polytobacco use among NH Black adults (OR: 1.05, 95% CI: 1.002–1.11) and NH White adults (OR: 1.18, 95% CI: 1.13–1.22). While more discrimination was associated with TUD among all racial/ethnic groups, the relationship was the strongest for NH White adults. Conclusions: Discrimination was associated with more severe tobacco use outcomes among multiple racial/ethnic groups, but associations were the strongest for NH White adults.
