Abstract
Smoking, a leading cause of chronic respiratory disorders, is elevated among sexual minority (i.e., lesbian, gay, and bisexual) individuals. Elevations in smoking among sexual minority individuals may contribute to increased rates of chronic respiratory disorders among older sexual minority individuals. Data from 161,741 individuals (3.6% sexual minorities) aged 45 and older from the 2020 Behavioral Risk Factor Surveillance System were used to examine disparities in chronic respiratory disorders among older sexual minority individuals. Mediation was used to analyze a model with smoking mediating the relationship between sexual minority identity and self-reported chronic respiratory disorder. The results indicated that smoking mediated the relationship between sexual minority identity and self-reported chronic respiratory disorder. Smoking was 1.2 times more common, and the prevalence of chronic respiratory disorders was 1.2 times higher, among sexual minority individuals compared to heterosexual individuals. The present study indicates that smoking disparities observed among sexual minority individuals are linked to increased risk for chronic respiratory disorders, and also indicate that sexual minorities have an excess burden of chronic respiratory disorders.
