Interactions of Sexual Orientation and Gender Identity with Race/Ethnicity in Prevalence of Lifetime and Current Asthma Diagnosis.

The current study explored how sexual orientation and gender identity interact with race/ethnicity to predict self-reported lifetime and current diagnosis of asthma. Using the 2020 Behavioral Risk Factor Surveillance System survey, we conducted logistic regression analyses, weighted for complex samples, stratified by sexual orientation and gender identity, and controlling for race/ethnicity, age, smoking, population density, and body mass index. Analyses showed that there were significantly higher adjusted odds of lifetime asthma among gay men and bisexual men in comparison to heterosexual men, gay/lesbian women and bisexual women in comparison to heterosexual women, and transgender men in comparison to cisgender individuals. In addition, analyses showed that there were significantly higher odds of current asthma among women with other minority sexual orientations in comparison to heterosexual women. Finally, there was a significant interaction between race/ethnicity and sexual orientation among men. Sexual minority men of color might be particularly vulnerable to chronic asthma. Future research should examine asthma prevalence in sexual and gender minority (SGM) individuals of specific marginalized racial/ethnic groups. Future responses to SGM asthma inequities should include low-cost screening and treatment targeting SGM individuals, and policies improving air quality in urban areas.
