An intersectional approach to examine sleep duration in sexual minority adults in the United States: findings from the Behavioral Risk Factor Surveillance System.

Objectives: Investigate sexual identity differences in sleep duration and the multiplicative effect of sexual identity and race/ethnicity among US adults.

Design: Cross-sectional.

Participants: The sample consisted of 267,906 participants from the Behavioral Risk Factor Surveillance System.

Measurements: Sleep duration was categorized as very short (≤4 hours), short (5-6 hours), adequate (7-8 hours), or long (≥9 hours). Sex-stratified multinomial logistic regressions were used to examine sexual identity differences in sleep duration. We then examined sleep duration by comparing sexual minorities to (1) same-race/-ethnicity heterosexuals and (2) White participants with the same sexual identity.

Results: Sexual minority women had higher odds of very short sleep compared to heterosexual women, regardless of race/ethnicity. Black gay men had higher rates of very short sleep but lower rates of long sleep relative to Black heterosexual men. Latino and Asian/Pacific Islander bisexual men reported higher rates of short sleep than their heterosexual counterparts. Black lesbian and other-race bisexual women were more likely to have very short sleep than their heterosexual peers. Black lesbian women also had higher rates of long sleep. Analyses examining racial/ethnic differences by sexual identity found that Black and Latino gay men reported higher rates of very short sleep compared to White gay men. Black bisexual women had higher rates of short sleep duration than White bisexual women.

Conclusions: More research is needed to understand how to promote sleep health among sexual minorities, particularly racial/ethnic minorities, and the impact of inadequate sleep duration on health outcomes in this population.
