Introduction: Suicide attempt is a worldwide major public health problem, that accounts for 1.4% of all deaths worldwide Recent literature reported a higher risk of suicide attempt among adolescents associated with sexual minority status but few systematic reviews focused on the risk and protective factors. For that reason, it seems necessary to examine the risk and protective factors of attempted suicide in sexual minority adolescents.
Methods: We conducted a systematic review of published studies on factors associated with suicide attempts in LGBT adolescents. 4 databases up to December 2020 were searched to find relevant studies.
Results: In addition to the factors usually found in the general population (gender, ethnic minorities, childhood trauma, psychiatric symptoms, addictive behaviors), some factors have been independently associated with suicide attempts in the LGBT population: early coming out, not acceptable by families, not satisfied with LGBT friendship, too few numbers of friends, physical abuse, sexual abuse, and bullying. The protective factors of suicide attempts reported in the LGBT population were feeling safe at school, teacher support, anti-bullying policy, and other adult support.
Conclusion: Effective preventive measures for suicide attempts among LGBT youth need to be developed and implemented. The impact of interventions targeting teacher responses to LGBT stigma, discussion of LGBT issues in class, and reactions of family and friends to the coming out of LGBT youth should be further investigated.
