Socio-demographics, sexual behaviours, and use of HIV prevention services among men who have sex with men and women in Western China.

This paper looks into the differences of sexual risk behaviours and prevention services among men who have sex with men and women and men who have sex with men only. The data from a cross-sectional survey of 159 men who have sex with men and women and 1186 men who have sex with men only in western China is analysed. It is found that men who have sex with men and women, with multiple anal sex partners, have higher rates of selling and buying sex than men who have sex with men only, but obtain less HIV-related knowledge from partners or HIV consulting and testing services. More efforts should be made to promote safer sexual behaviours and reduce the barriers for access to health services.
