摘要
目的了解男男性行为者（MSM）HIV、梅毒螺旋体的感染状况和该人群中危险性行为现状及其影响因素。方法2008年4～8月在北京、哈尔滨、郑州和成都4座城市采用滚雪球法招募测查对象，对其进行HIV、梅毒螺旋体的血清学检测及问卷调查。问卷内容包括社会人口学资料、性伴和性行为特征。结果调查对象共1693名，其中单纯男男性行为者（MSM／M）1390名，占82．1％；男男性行为兼异性性行为者（MSMW）303名，占17．9％。MSM／M、MSMW人群HIV感染检出率分别为7．0％（97／1390）和6．6％（20／303），梅毒螺旋体感染检出率分别为11．9％（166／1390）和13．2％（40／303）最近61＼月同性肌交从未使用、有时使用安仝套者所占比例在MSM／M人群分别为8．6％（120／1390）、45．3％（630／1390），任MSMW人群分别为10．2％（31／303）、44．6％（135／303），在MSM／M人群中，危险性行为的影响因素包括：拥有性伴数〈6名（OR：6．03，90％CI：2．54～14．28）、无男性固定性伴（OR：2．18，90％CI：1．30～3．65）、无男性偶然性伴（OR：2．90，90％CI：1．79～4．71）、肛交时仅为插入方（OR=1.64，90％CI：1．13～2．37）、肛交时仅为被插入方（OR：1．58，90％C1：1．04～2．41）。在MSMW人群中，危险性行为的影响因素包括：拥有性伴数〈6名（OR=12．95，90％C1：2．38～70．52）、无男性同定性伴（OR=0．42，90％CI：0．21～0．85）及异性性行为从不使用安全套（OR=3．53，95％CI：1．48～8．42）。结论MSM人群中HIV和梅毒螺旋体感染均处于较高水平，危险性行为普遍存在，其危险因素包括拥有性伴数〈6名、无男性鸺然性伴、肛交时仅为插入方、肛交时仅为被插入方及MSMW者异性性行为从不使用安全套。无男性固定性伴在MSM／M人群为危险因素，而有男性固定性伴在MSMW人群为危险因素。
Objective 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. Methods 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. Results 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 samesex 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 regulate 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）. Conclusion 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 sexual partners,no same-sex casual sexual partener, 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 MSM/M population,while having same-sex regular partners was a risk factor in MSMW popu ation.
