OBJECTIVE: To investigate the AIDS-related high risk behaviors of men who have sex with men (MSM) who ever exchanged money for the same sex.
METHODS: Target sampling for cross-sectional study and valid anonymous questionnaires were adopted to compare the differences of AIDS-related high risk behaviors between MSM with the experience of exchanging money for the same sex and those without that experience. 1959 rstadied samples were recruited in nine cities. SPSS 13.0 was used and t, χ(2) and Mann-Whitney tests were taken for statistical analysis.
RESULTS: Compared to corresponding ones without "buying" the same sex experience, MSM who ever engaged in "buying" sex had the characteristics of being prone to in marriage and living in larger cities with older age and higher income (P < 0.01). They also had a significant larger number in the following events: total sexual partners, anal sex and oral sex episodes with same sex, number of sexual partners, anal sex and oral sex in the previous six months, with the figure of median 50.0, 20.0, 20.0, 5.0, 4.0, 5.0 respectively. 31.5% had ever participated in ‘group sex’, 48.0% had sex with male partners away from his own region in the previous year, 70.5% had sexual intercourse with strangers at MSM avenues in the last six months. The OR (95%CI) values were 2.288 (1.702 – 3.077), 3.231 (2.462 – 4.241), 2.840 (2.140 – 3.770). All the above mentioned figures were higher than those without the experience, with significant differences. They had a significant lower rate of 45.7% of condom use while having sex with female partners (P < 0.05).
CONCLUSION: MSM with the experience of exchanging money for the same sex would have more AIDS-related high risk behaviors, AIDS preventative measures should be taken to target different subgroups.
