To understand the prevalence of group sex in men who have sex with men (MSM) and related factors in Taizhou, Zhejiang province. 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. 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 19.0, (2)=125.527, <0.01), had both male and female sexual partners (86.6 68.2, (2)=31.935, <0.01), used no condom at sex with female partners during the past year (28.1 19.8, (2)=6.540, <0.05). After adjusted for educational level and occupation, group sex was associated with age[≥50 years old . ≤24 years old, adjusted odds ratio (a)=2.25, =0.027], marriage with female (divorced or widowed. unmarried, a=0.29, =0.001), census registering (local resident . non-local resident, a=1.56, =0.023), number of male seuxal partners (≥21 . 2-5, a=8.06, <0.001; 11-20 . 2-5, a=3.25, <0.001) and number of female seuxal partners (≥6 . 0, a=2.63, =0.005; 2-5 . 0, a=2.58, =0.001; 1 . 0, a=2.01, =0.010). 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.
了解浙江省台州市男男性行为者（MSM）群体性行为的流行情况及其相关因素。2013年3月至2015年9月，采用问卷调查的方式，对从台州市同性恋酒吧或浴场招募的男男性行为者进行横断面调查，收集他们的性行为及HIV检测信息。共招募1435名男男性行为者，其中179人（12.5%）感染HIV，231人（16.1%）报告在过去一年中有群体性行为。与无群体性行为的男男性行为者相比，有群体性行为的男男性行为者有10个以上男性性伴的比例更高（53.7% 对19.0%，χ²=125.527，P<0.01），有男性和女性性伴的比例更高（86.6% 对68.2%，χ²=31.935，P<0.01），过去一年与女性性伴发生性行为时不使用避孕套的比例更高（28.1% 对19.8%，χ²=6.540，P<0.05）。在调整教育程度和职业后，群体性行为与年龄[≥50岁 对≤24岁，调整后的优势比（aOR）=2.25，P=0.027]、与女性结婚（离婚或丧偶 对未婚，aOR=0.29，P=0.001）、户籍登记情况（本地居民 对非本地居民，aOR=1.56，P=0.023）、男性性伴数量（≥21个 对2 - 5个，aOR=8.06，P<0.001；11 - 20个 对2 - 5个，aOR=3.25，P<0.001）以及女性性伴数量（≥6个 对0个，aOR=2.63，P=0.005；2 - 5个 对0个，aOR=2.58，P=0.001；1个 对0个，aOR=2.01，P=0.010）有关。台州市男男性行为者群体性行为的流行率较高，其不良的避孕套使用情况和复杂的性行为会导致更高的HIV感染率和传播风险。
