Psychosocial and Behavioral Correlates of Sleep Duration and Sleep Disturbance Among Lesbian, Gay, and Bisexual Women

INTRODUCTION: Sleep is an essential dimension of good physical and mental health. Lesbian, gay, and bisexual (LGB) women experience inequities in sleep duration and disturbance compared to heterosexual women. Psychosocial and behavioral characteristics are important to sleep in the general population; they may advance our understanding about sleep inequities among LGB women and provide key information for developing promising interventions. METHODS: Data for this project were provided by the Women's Health Initiative (WHI). The sample size for this project was 1436: 884 LG women and 552 bisexual women. Outcome variables were sleep duration and disturbance. The authors sought to clarify the associations, including the strength, between psychosocial factors and sleep outcomes among LGB women. Associations between psychosocial characteristics, health behaviors, and sleep outcomes were tested using multivariable, hierarchical, nested, linear regression models, stratified by sexual orientation. RESULTS: Social strain, social function, optimism, and negative emotional expressiveness were significantly associated with sleep outcomes for LGB women. Health behaviors were not consistently or strongly associated with sleep outcomes for LGB women. CONCLUSIONS: The findings point to the importance of social strain, social function, negative emotional expressiveness, and optimism in LGB women's sleep. It is possible that LGB women's sleep could be improved with evidence-based interventions that use our findings.
