[Study on high-risk behaviour and suicide associated risk factors related to HIV/AIDS among gay or bisexual men].

OBJECTIVE: Characteristics on AIDS high-risk behaviors in gay or bisexual men with suicide ideas were explored and analyzed. METHODS: A cross-sectional survey was conducted with the snowball sampling method adopted. Subjects with suicide ideas were collected from responses to the valid questionnaires and subjects with no suicide ideas were collected from the age comparable men. RESULTS: The overall rate of gays or bisexuals with suicide ideas was 20.2% in this survey. The attitude for homogeneity and marital status among the unmarried was more than that among the comparable group (P < 0.05). The rate of AIDS high-risk behaviors as same-sex sexual harassment, bleeding during sexual intercourse in the last year, coitus with unfamiliar same-sex partners in cities, suffering from adult same-sex sexual abuse before the age of 16, having had sexual abuse and abusive behavior, having had active or passive anal kiss, having had active or passive coitus with fingers, alcohol consumption weekly at least once or more, hurt by gays because of attitude and/or same-sex sexual activity and hurt by heterosexual men because of attitude and/or same-sex sexual activity were significantly higher in gays and bisexual men with suicide ideas than those without (P < 0.05). Data from multivariate logistic regression models suggested that harm from gays (Waldχ(2) = 6.637, P = 0.010) and heterosexual men (Waldχ(2) = 5.835, P = 0.016) due to attitude on homosexual activity appear to be the risk factors causing the suicide ideas. CONCLUSION: Reducing the social discrimination and harm towards gays and bisexual men could reduce the occurrence of the suicide ideas and have a positive effect on curbing the prevalence of AIDS.
