This article examines a stratified random sample of 750 males in Calgary, Canada, aged 18-27, who were given questions on sexual activity, orientation, & suicide. Almost 13% of the males were classified as homosexual or bisexual on the basis of being currently homosexually active or by self-identification. Significantly higher rates of previous suicidal ideas & actions were reported by homosexually oriented males then heterosexual males. Homosexually oriented males accounted for 62.5% of suicide attempters. These findings indicate that homosexual males are 13.9 times more at risk for a serious suicide attempt. (67 refs.) (AK)
