Objectives: To describe and analyze HIV/AIDS/STD-related high risk behaviors and affecting factors of men who have sex with men (MSM) in mainland China~ Methods: 426 self-administered or interview-based questionnaires collected from MSM were analyzed with SPSS or SAS Systems. Results: Of the MSM, four-fifths had engaged in oral-genital intercourse, about half had engaged in anal intercourse, and in the past year more than two-fifths had casual sexual partner(s).Very few maintained monogamous sexual relationships, and nearly half also had intercourse with women. One fourth had previously been diagnosed with a venereal diseases. One HIV+individual was found among the 40 who reported having been tested for HIV. Only two men consistently used condoms among the one-third who had ever used condoms, despite almost universal knowledge of HIV and its transmission. Conclusions: MSM in mainland China are very sexually active, highlighting the possibility of a serious HIV epidemic that may be directly spread to the female population. However,AIDS interventions targeting MSM face severe obstructions resulting from cultural bias and other factors.
