Prevalence and Sociodemographic and Behavioral Correlates of Psychological Distress among Lesbian, Gay, and Bisexual Adults in the United States, 2013-2018

Abstract

Background: The lesbian, gay, bisexual, and transgender (LGBT) population comprises approximately 5.6% of the total US population. Levels and patterns of psychological distress in the LGBT population are less well known compared with the general population. This study examines the prevalence and sociodemographic and behavioral correlates of psychological distress among lesbian, gay, and bisexual (LGB) adults in the United States. Methods: Using the pooled cross-sectional data from the 2013-2018 National Health Interview Surveys (N=183,020), differentials in serious psychological distress (SPD) and factor-based psychological distress scores were analyzed by multivariate linear and logistic regression. Results: The prevalence of SPD was 8.0% for the LGB population aged ≥18, 7.0% for gay and bisexual males, and 8.9% for LGB females, compared with 3.4% for the total straight/heterosexual population, 2.7% for straight males, and 4.0% for straight females. Mean psychological distress index scores were highest among LGB females (109.8), followed by gay and bisexual males (105.8), straight females (100.6), and straight males (97.7). Compared with the straight population, LGB adults had higher education, unemployment, and poverty levels and were more likely to be non-Hispanic White and single. LGB adults were more likely to smoke and drink alcohol and more likely to be physically active than straight adults. LGB females had higher obesity but gay and bisexual males had lower obesity rates than their straight counterparts. After controlling for covariates, LGB adults had 89% higher odds of SPD and significantly higher distress levels than straight adults. Younger age, lower-income, divorce/separation, lack of health insurance, functional limitation, smoking, physical inactivity, and obesity were significant predictors of SPD and higher psychological distress levels in LGB adults. Conclusion and Implications for Translation: Significant disparities in mental health exist, with LGB adults at substantially increased risk of psychological distress and likely in greater need of appropriate social and mental health services. Health policies aimed at improving the material conditions and social environments may lead to improved mental health outcomes among LGB adults and the general population.
