ABSTRACT
<p><b>OBJECTIVE</b>To investigate HIV and treponema pallidum infection status, risky sexual behavior among men who have sex with men (MSM) and its impact factors in China.</p><p><b>METHODS</b>Snowball sampling was used to recruit subjects from April to August in 2008 in Beijing, Harbin, Zhengzhou and Chengdu city. Serological test of HIV and treponema pallidum were conducted and a questionnaire survey was undertaken among subjects. The questionnaire included social demographics, characteristics of sexual partners and sexual behaviors.</p><p><b>RESULTS</b>A total of 1693 subjects was enrolled in present study, which included 1390 MSM/M (82.1%) and 303 MSMW (17.9%). The infection rate of HIV among MSM/M and MSMW subjects were 7.0% (97/1390) and 6.6% (20/303), respectively. The infection rate of treponema pallidum among MSM/M and MSMW subjects were 11.9% (166/1390) and 13.2% (40/303), respectively. The proportions of MSM/M subjects who never used or sometimes used condoms when having same-sex anal intercourse in recent 6 months were 8.6% (120/1390), 45.3% (630/1390), respectively. The according proportions among MSMW subjects were 10.2% (31/303), 44.6% (135/303), respectively. Among MSM/M subjects, the risk factors of risk sexual behaviors included having less than 6 sexual partners (OR = 6.03, 95%CI: 2.54 - 14.28), no same-sex regular sexual partner (OR = 2.18, 95%CI: 1.30 - 3.65), no same-sex casual sexual partner (OR = 2.90, 95%CI: 1.79 - 4.71), T-pattern only during anal intercourse (OR = 1.64, 95%CI: 1.13 - 2.37) or P-pattern only (OR = 1.58, 95%CI: 1.04 - 2.41). Among MSMW subjects, the risk factors of same-sex risk sexual behaviors included having less than 6 sexual partners (OR = 12.95, 95%CI: 2.38 - 70.52), no same-sex regular sexual partners (OR = 0.42, 95%CI: 0.21 - 0.85), never used condom during heterosexual intercourse (OR = 3.53, 95%CI: 1.48 - 8.42).</p><p><b>CONCLUSION</b>The infection rate of HIV and treponema pallidum among MSM subjects were quite high, and the same-sex risk sexual behaviors among MSM subjects were ubiquity, whose risk factors including having less than six of sexual partners, no same-sex casual sexual partner, T-pattern or P-pattern only during anal intercourse and never used condemn during heterosexual intercourse among MSMW subjects no same-sex regular partner was a risk factor in MSMS population, while having same-sex regular partners was a risk factor in MSMW population.</p>
