Using univariate General Linear Models and controlling for age, ethnicity, and SGM visibility, we found a significant interaction between being African American and facing housing insecurity on experiences with SGM discrimination [F(1,220)=7.21, p=0.01], perceived smoker stigma [F(1,220)=5.48, p=0.02], perceived differential treatment due to smoking [F(1,220)=10.03, p=0.00], and social withdrawal from non-smokers [F(1,220)=6.18, p=0.01]. These interactions suggest that economically-disadvantaged African American SGM current or former smokers experience increased levels of discrimination and perceive more smoking-related stigma compared to other SGM current and former smokers. Conclusions: Results suggest that people's multiple identities intersect to intensify oppression and inequities for some people and raise questions about the unintended consequences of stigmatizing smokers for reducing smoking among SGM adults.
