Suicidality and Sexual Orientation in Five Continents: Asia, Australia, Europe, North America, and South America

This study examined the relation between suicidality and sexual orientation in an intercontinental sample (Asia, Australia, Europe, North America, and South America). Participants responded to a survey hosted on the Internet Website of an international news organization. Categorical analyses compared homosexual and bisexual respondents' history of suicide attempts and suicide ideations to those of heterosexual respondents, by total sample, males only, and females only. A relation between male sexual orientation and suicide attempts was found for every continent except Europe (odds ratio [OR] 1.5; 95% confidence interval [CI] = 0.3, 6.9). A relation between female sexual orientation and suicide attempts was not found in any continent except North America (OR = 2.1; 95% CI % 1.7, 2.5). These data provide preliminary evidence of intercontinental variation in the relation between suicidality and sexual orientation.
