Mental Disorders and Suicidality by Sexual Orientation Status Among First-Year College Students in France.

Studies indicate that non-heterosexual young adults experience higher rates of mental health problems in various settings. This study seeks to further explore these associations, distinguishing heterosexual, gay/lesbian, bisexual and individuals questioning their sexual identity. Data were drawn from the French portion of the World Mental Health International College Student survey initiative (n = 3,545). Logistic regressions were performed to estimate the associations of sexual orientation with 12-month mental disorders and suicidal ideation and behaviors. Overall, 81.6% (n = 2,894) of students identified as heterosexual, 2.9% (n = 103) as gay/lesbian, 8.5% (n = 302) as bisexual and 6.9% (n = 246) stated questioning their sexual orientation. In adjusted models, compared to heterosexuals, students identifying as bisexual reported greater odds of major depression, panic disorder, drug use disorder and suicidality, gay/lesbian students were more likely to present with panic disorder, suicidal ideation and plans, and students questioning their sexual orientation were at greater risk for generalized anxiety disorder, suicidal ideation, and plans. The study confirmed higher rates for mental health disorders for non-heterosexual young adults, with little evidence of significant differences between minority subgroups.
