Objective

Sexual and gender minorities are at elevated risk for suicide, yet few studies have examined differences in risk within many sexual and gender minority subgroups. The purpose of this study was to examine differences in prevalence for suicide risk factors among a wide range of sexual orientations and gender identities.

Method

Forty-one thousand four hundred and twelve college students (62% cis-female, 37% cis-male, 1% transgender/genderqueer) completed a wellness screen that included four suicide risk factors (depression, heavy alcohol use, suicide ideation, suicide attempt).

Results

Gender minority students (i.e., transgender, genderqueer/non-binary) had significantly higher rates of depression, suicide ideation, and suicide attempts relative to cisgender peers, although there were no within-group differences among gender minority students. Adjusted odds ratios for endorsing two or more (2+) suicide risk factors were substantially higher for all sexual minority subgroups relative to heterosexuals. Among sexual minorities, those identifying as pansexual, bisexual, queer, or mostly gay/lesbian had greater odds of endorsing 2+ suicide risk factors relative to students identifying as mostly heterosexual, gay/lesbian, asexual, or 'other sexual minority'. Pansexual students had 33% greater odds of endorsing 2+ suicide risk factors relative to bisexual students.

Conclusions

These findings highlight significant variation in suicide risk among sexual minority subgroups and the need for targeted interventions for subgroups at highest risk.
