Risk factors for suicide attempt among adolescents reporting suicidal ideation by sexual and gender minority status: Evidence from the 2022 Minnesota Student Survey

Background: Suicide is a leading cause of death among adolescents, yet most adolescents who report suicidal ideation do not attempt nor die by suicide. To prevent injury and death, it is thus vital to explore factors potentiating the transition from suicidal ideation to suicidal attempt, especially in high-risk groups like sexual and gender minority (SGM) adolescents. Guided by an "ideation-to-action"framework, we explored risk factors for suicide attempt (ie, "painful and provocative experiences") among adolescents reporting suicidal ideation by SGM status. Methods: Data were drawn from the cross-sectional 2022 Minnesota Student Survey and restricted to 10 561 adolescents reporting past-year suicidal ideation (52.3% SGM; 47.7% non-SGM). Analyses first assessed prevalence of exposure to painful and provocative experiences (ie, non-suicidal self-injury, adverse childhood experiences, bullying) by SGM status. Then, in multivariable logistic regression models, analyses probed associations between these risk factors and past-year suicide attempt. Results: Among adolescents reporting recent suicidal ideation, a higher proportion of SGM adolescents reported past-year suicide attempt than non-SGM adolescents (26.7% vs 21.6%, respectively). All examined painful and provocative experiences were more commonly reported among SGM adolescents. In analyses restricted to SGM adolescents, non-suicidal self-injury, sexual abuse by a family member, and bullying demonstrated the largest effect sizes of associations with suicide attempt. Discussion: Guided by an "ideation-to-action"framework, this research identifies risk factors potentiating suicide attempt in SGM adolescents reporting recent suicidal ideation. Structural and clinical interventions focused on mitigating exposure to painful and provocative experiences may help to prevent suicide among SGM adolescents.
