[Disparities in mental health associated with sexual orientation among Mexican adolescents].

The aim of this study was to document disparities in mental health related to discrimination based on sexual orientation in Mexican adolescents. A representative national sample of secondary school students was analyzed. Criteria for homosexual orientation were having had a same-sex boyfriend or girlfriend and having had same-sex sexual relations. The events were: depression, low self-esteem, suicidal ideation, attempted suicide, smoking, alcohol abuse, and drug use. Teenagers with same-sex relationships or sexual relations had an increased risk of depressive symptoms, suicidal ideation, attempted suicide, and alcohol abuse. These differences were particularly related to having experienced violence in the family and in school. Despite institutional and legal progress in acknowledging the rights of the lesbian, bisexual, and gay population, health inequities persist due to discrimination based on sexual orientation.
