摘　　要：目的探讨我国男男性接触者（MSM）性伴状况与性传播感染（STI）感染率相关关系。方法采用匿名自填问卷方式对9城市MSM进行调查，用SPSS 11．0软件处理。结果STI组男性伴数量多于非STI组（P〈0．05），自身性伴为较少性伴者的STI感染率低于有较多性伴者（P〈0．05）。通过公厕、公园或浴池结识性伴者的STI感染率，高于通过同学朋友邻居结识性伴者（P〈0．05）。自认为与性伴关系彼此专一者的STI感染率明显低于与性伴关系非彼此专一者（P〈0．01）。在婚者STI感染率高于非在婚者（P〈0．05），与妻子分居者STI感染率高于与妻子仍有性行为者（P〈0．05）。结论减少MSM的男性伴数量，可以降低STI感染率。通过公厕、公园或浴池等场所结识性伴是MSM人群STI／HIV传播的重要途径。MSM中STI／HIV感染存在异性性传播的风险。Objective To study the relationship between sexual partner status and sexually transmitted infection （STI） incidence among men who have sex with men （MSM） in China. Methods Anonymous questionnaires were designed and delivered to survey 2265 MSM in 9 Chinese cities, including Harbin, Shenyang, Nanjing, Shanghai, Zhengzhou, Wuhan, Xi＇an, Chongqing and Chengdu. Collected data were analyzed by SPSS 11.0. Results Totally, 2250 valid questionnaires were returned, with a response rate of 99.3%. STI occurred in 17.7% （399/2250） of the participants. The number of male sexual partners of MSM with STI was greater than those without STI （81.29 ±9.17 vs 67.15±6.65, t = 2.611, P 〈 0.05）. MSM whose sexual partners had fewer sexual partners showed a lower STI incidence compared with those whose sexual partners had more （P 〈 0.05 ）. STI incidence increased in MSM who got acquainted with sexual partners in public lavatory, park and bathroom in comparison with those who met sexual partners through classmates, friends and neighbors. MSM who had single fixed sexual partner had a lower STI incidence than those who had more than one fixed sexual partners （P 〈 0.01 ）. A higher STI incidence was also observed in MSM who were in marriage versus those out of marriage （P 〈 0.05）, and in MSM who separated with their wives versus those who cohabited （P 〈 0.05）. Conclusions The decrease in male sexual partners may facilitate the reduction in STI incidence. Meeting sexual partners in public lavatory, park and bath may be an important transmission route of STIfHIV. Heterosexual behavior is a risk for STI transmission in MSM.
