Sleep has been found to be essential to physical and mental health. Sexual and gender minority (SGM
e.g., lesbian, gay, bisexual, transgender, nonbinary) individuals experience significant health disparities, and emerging research indicates that this includes disparities in sleep health. However, the current literature on sleep health in this population has not previously been rigorously reviewed. This scoping review provides a comprehensive overview and synthesis of the current literature on SGM sleep health in the United States. Following established scoping review methodology, we systematically searched PubMed, CINAHL, PsycINFO, LGBTQ + Source, and Scopus
76 studies met inclusion criteria. Included studies indicated significant sleep disparities exist for SGM people, particularly sexual minority women and gender minority people. Social determinants of health, including bullying and discrimination, were associated with worse sleep health. Included studies were heterogeneous and had methodological weaknesses, leaving opportunities for future research. Overall, findings point to the need for more rigorous research to advance understanding of sleep health across SGM subgroups and inform interventions to improve sleep health among SGM people, given the known negative impact of poor sleep on overall health.
