Associations between Korean Adolescents' Sexual Orientation and Suicidal Ideation, Plans, Attempts, and Medically...

Despite growing interest in the public health of sexual minority, youth around the world due to the high rates of suicidal ideation and attempts in this population, few studies on the sexual orientation of Korean adolescents have been conducted. Therefore, this study investigated the relationship between the sexual orientation of Korean adolescents and their suicide-related behavior.

Raw data from the tenth Korea Youth Risk Behavior Web-based Survey were analyzed by logistic regression analysis. The sample consisted of 3603 adolescents who provided selected demographic variables and reported on their experience of sexual intercourse with the same or the opposite sex, along with lifestyle and suicide-related behaviors.

Rates of suicidal ideation, plans, attempts, and medically serious attempts were higher in both homosexual and bisexual than heterosexual groups. Suicidal ideation (odds ratio 95% confidence interval: 1.09-2.08), suicidal plans (odds ratio 95% confidence interval: 1.01-2.09), and suicide attempts (odds ratio 95% confidence interval: 1.28-2.88) had the strongest associations with homosexuality after multivariate adjustment. In contrast, bisexuality was only significantly associated with suicidal attempts (odds ratio 95% confidence interval: 1.01-2.97) after multivariate adjustment.

Effective suicide prevention interventions are required for homosexual and bisexual adolescents, in the form of targeted programs to improve their mental health status and ability to cope with stress.
