Résumé

Purpose - Disparities in mental health across sexual orientation groups and among young adults have long been discussed. The aim of this cross-sectional study was to investigate the moderating effects of sexual orientation on the associations between social factors and depressive symptoms as well as suicidal ideation in young adults. Methods - The study included 6,337 participants aged 18-25y in 2022 from the French EpiCov cohort. The outcome variables were depressive symptoms and suicidal ideation. Poisson regressions with robust error variance were performed to investigate the associations between social factors and outcomes according to sexual orientation (lesbian, gay, bisexual, other, or not defining themselves according to their sexuality: sexual minority (SM); heterosexual or not wishing to answer: Not belonging to SM (NSM)). Results - The prevalence of depressive symptoms and suicidal ideation was higher in the SM than in the NSM group. Regarding depressive symptoms, significant moderating effects of sexual orientation were observed for female vs male sex (NSM: adjusted Prevalence Ratio (aPR) 1.58[1.28-1.95], SM: aPR 1.03[0.78-1.36]) and age category 22-25y vs 18-21y (NSM: aPR 1.32[1.05-1.67], SM: aPR 0.78[0.59-1.03]). Regarding suicidal ideation, significant moderating effect was observed for not being vs being in a relationship (NSM: aPR 1.55[1.14-2.12], SM: aPR 0.82[0.59-1.13]). Conclusion - In this study conducted in 2022, well-known social risk factors of mental problems do not explain the higher prevalence of depressive symptoms and suicidal ideation among young SM group. Further studies are needed to understand the specific challenges faced by these young people.
