| 目的 了解浙江省台州市MSM同性群交行为特征及其相关因素。方法 2013年3月至2015年9月，经浴室、酒吧等场所招募MSM，通过问卷调查收集其性行为等信息，并进行HIV检测。使用logistic回归模型分析群交行为相关因素。结果 共调查1 435名MSM，HIV阳性率为12.5%（179/1 435）。16.1%（231/1 435）报告在最近1年曾有群交行为。最近1年有群交行为的MSM与最近1年无群交的MSM相比，一生同性性伴数≥10个（53.7%比19.0%，χ2=125.527，P<0.01）、有异性性伴（86.6%比68.2%，χ2=31.935，P<0.01）、最近1年与女性发生性行为未使用安全套（28.1% 比19.8%，χ2=6.540，P<0.05）的比例更高。多因素logistic回归模型分析显示，与MSM群交行为相关因素包括年龄（≥50岁比≤24岁，aOR=2.25，P=0.027），与女性婚姻（离异或丧偶比未婚，OR=0.29，P=0.001），户籍（本地比外地，aOR=1.56，P=0.023），一生同性性伴数（≥21个比2~5个，aOR=8.06，P<0.001；11~20个比 2~5个，aOR=3.25，P<0.001），一生异性性伴数（≥6个比0个，aOR=2.63，P=0.005；2~5个比0个，aOR=2.58，P=0.001；1个比0个，aOR=2.01，P=0.010）。结论 台州市MSM人群群交行为比例较高、安全套使用率低、性行为关系复杂，HIV感染率高、传播风险较大。 |

| Objective To understand the prevalence of group sex in men who have sex with men (MSM) and related factors in Taizhou, Zhejiang province. Methods From March 2013 to September 2015, a cross-sectional survey was conducted among MSM recruited from gay bars or bath houses in Taizhou by using questionnaire to collect the information about their sexual behavior and HIV test. Results A total of 1 435 MSM were recruited, 179 of them (12.5%) were HIV infected, 231 (16.1%) reported group sex during the past year. Compared with MSM without group sex, more MSM with group sex had more than ten male sexual partners (53.7% vs. 19.0%, χ2=125.527, P<0.01), had both male and female sexual partners (86.6% vs. 68.2%, χ2=31.935, P<0.01), used no condom at sex with female partners during the past year (28.1% vs. 19.8%, χ2=6.540, P<0.05). After adjusted for educational level and occupation, group sex was associated with age [≥50 years old vs. ≤24 years old, adjusted odds ratio (aOR)=2.25, P=0.027], marriage with female (divorced or widowed vs. unmarried, aOR=0.29, P=0.001), census registering (local resident vs. non-local resident, aOR=1.56, P=0.023), number of male seuxal partners (≥21 vs. 2-5, aOR=8.06, P<0.001; 11-20 vs. 2-5, aOR=3.25, P<0.001) and number of female seuxal partners (≥6 vs. 0, aOR=2.63, P=0.005; 2-5 vs. 0, aOR=2.58, P=0.001; 1 vs. 0, aOR=2.01, P=0.010). Conclusion The prevalence of group sex in MSM was high in Taizhou, and their poor condom use and complex sex behaviors would result in higher HIV infection rate and risk of transmission. |
