Methods Target sampling forcross-sectional study and valid anonymous questionnaires were adopted to compare the differences ofAIDS-related high risk behaviors between MSM with the experience of exchanging money for thesame sex and those without that experience. 1959 rstadied samples were recruited in nine cities. SPSS13.0 was used and t, x 2 and Mann-Whitney tests were taken for statistical analysis. ResultsCompared to corresponding ones without ＂buying＂ the same sex experience, MSM who ever engagedin ＂buying＂ sex had the characteristics of being prone to in marriage and living in larger cities witholder age and higher income （P〈0.01）. They also had a significant larger number in the followingevents： total sexual panners, anal sex and oral sex episodes with same sex, number of sexualpartners, 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 malepartners away from his own region in the previous year, 70.5% had sexual intercourse withstrangers 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 werehigher 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.
