Associations between Perceived Racial Discrimination and Tobacco Cessation among Diverse Treatment Seekers.

Objectives: This study investigated a) racial/ethnic differences in past-year discrimination experiences and b) associations between discrimination and smoking abstinence.
Design: Prospective, longitudinal analysis of smoking status. Perceived past-year discrimination was assessed at baseline. ANCOVAs and intent-to-treat hierarchical logistic regressions were conducted.
Setting: Dual-site (Tampa, FL and Miami, FL) randomized controlled trial testing the effects of a group cessation intervention plus pharmacotherapy.
Participants: Treatment-seeking adult smokers (N=347; non-Hispanic White, non-Hispanic African American/Black, or Hispanic).
Main Outcome Measures: Biochemically verified 7-day point prevalence abstinence (7-day ppa) was assessed immediately post-intervention and at 6-month follow-up.
Results: After controlling for covariates, African Americans/Blacks reported greater perceived discrimination compared with non-Hispanic Whites (P=.02), and Hispanics (P=.06). Non-Hispanic Whites and Hispanics did not differ in perceived racial/ethnic discrimination experiences over the past year. Irrespective of race/ethnicity, past-year perceived discrimination was inversely associated with 7-day ppa, both post-intervention (AOR=.97, CI: .95-.99) and at 6-months (AOR=.98, CI: .96-.99). Among African Americans/Blacks, past-year perceived discrimination was inversely associated with 7-day ppa, both post-intervention (AOR=.95, CI: .92-.97) and at 6-months (AOR=.97, CI: .94-.99). Perceived discrimination was unrelated to 7-day ppa among Hispanics. Among non-Hispanic Whites, past-year perceived discrimination was inversely associated with post-intervention 7-day ppa (AOR=.95, CI: .91-.99), but not 6-months.
Conclusions: Perceived racial/ethnic discrimination was greater among African American/Black smokers compared with non-Hispanic Whites. Perceived discrimination was negatively associated with tobacco cessation in the full sample, and for African Americans at 6-months post-intervention. These data have implications for intervention delivery and health disparities.
