Objective To investigate the sexual behavior characteristics and knowledge awareness about AIDS among male college students in Fangshan District of Beijing, and provide evidence for AIDS prevention and control. Methods A total of 1 416 male college students from 8 colleges and universities in Fangshan District of Beijing were investigated by stratified random cluster sampling method from Marell to May in 2018. According to the questionnaire results, the students were divided into heterosexual. homosexual and bisexual groups. Results All 1 416 questionnaires were valid questionnaires. Among them, 87.78% were heterosexual,4.94% were homosexual and 7.27% were bisexual. The incidence of sexual behavior among heterosexual, homosexual and bisexual groups was 21.16%,42.86% and 36.89%, respectively. The differences had statistical significance(χ^2=28.751,P<0.01). The incidence of sexual behavior in homosexuals and bisexuals was higher than that in heterosexuals respectively (χ^2=17.998、13.564,P均<0.01) while the incidence of multiple sexual partners in homosexuals was higher than that in heterosexuals (χ^2=11.077,P<0.01);Condom usage every time of heterosexuals was higher than thatin bisexuals(χ^2=10.727,P<0.01). The detection rate of AIDS among homosexuals was higher than heterosexuals (χ^2=33.305,P<0.01). The awareness rate of male undergraduates of heterosexual, homosexual and bisexual groups should actively seek HIV testing and counseling after high-risk behaviors (needle sharing/unsafe sexual behavior, et al.) reached 90%. Conclusions The awareness rate of AIDS-related knowledge among male college students is low in fangshan, the risk of sexual intercourse is common.
