OBJECTIVES
The characteristics of men who have sex with men (either exclusively or with both men and women; MSM) who engaged in casual sex among Chinese male university students have not been compared with the characteristics of men who have sex with only women (MSW). This information is important for tailoring targeted behavioral interventions to prevent human immunodeficiency virus (HIV)/sexually transmitted infection (STI) transmission in this subgroup of MSM.
METHODS
Data were derived from a large cross-sectional electronic questionnaire survey conducted at 13 universities in Zhejiang Province, China, in 2018. Bivariate analyses were used to compare demographic, HIV-related psychosocial, and behavioral characteristics between MSM and MSW students who engaged in casual sex during the previous year. Proportion differences between the two groups and their 95% confidence intervals were analyzed.
RESULTS
Among the 583 sexually active male students who engaged in casual sex during the previous year, 128 and 455 were MSM and MSW, respectively. Compared with MSW students, larger proportions of MSM students reported knowing that male-to-male sexual behavior was the main mode of HIV transmission among Chinese students (62.5% vs. 45.5%), consenting to commercial sex (67.2% vs. 53.4%), wanting to know the HIV serostatus of partners before casual sex (65.8% vs. 51.3%), feeling at risk of HIV infection (40.5% vs. 11.8%), high condom-decision scale scores (55.3% vs. 42.6%), engaging in sex with ≥ 5 casual sex partners (44.6% vs. 25.9%), searching for casual partners online (89.2% vs. 51.3%), consuming alcohol before casual sex (64.8% vs. 45.0%), engaging in sex with regular partners (83.1% vs. 67.0%), engaging in commercial sex (54.2% vs. 26.4%), and visiting a clinic for voluntary counselling and testing (VCT) (16.4% vs. 8.4%). However, compared with MSW students, smaller proportions of MSM students reported knowing that consistent condom use could prevent HIV transmission (80.5% vs. 95.2%) and that VCT should be actively sought after risky sexual behavior (78.9% vs. 93.8%), using condoms sometimes/often (26.4% vs. 44.3%), and consistently using condoms (28.9% vs. 40.1%) while engaging in sex with casual partners.
CONCLUSIONS
MSM students who engaged in casual sex were at a greater risk of HIV/STI transmission, compared with MSW students. Comprehensive interventions to address the risks of unprotected male-to-male sex, searching for casual sex partners online, and non-use of HIV testing services are needed to reduce the burden of HIV/STI transmission among this subgroup of MSM.
目的
与仅与女性发生性关系的男性（MSW）相比，与男性发生性关系的男性（MSM）中发生随意性行为的特征尚未得到比较。这些信息对于针对该亚组的 MSM 量身定制有针对性的行为干预措施以预防人类免疫缺陷病毒（HIV）/性传播感染（STI）传播非常重要。
方法
数据来自于 2018 年在中国浙江省 13 所大学进行的一项大型横断面电子问卷调查。使用双变量分析比较了过去一年中发生随意性行为的 MSM 和 MSW 学生在人口统计学，HIV 相关的心理社会和行为特征方面的差异。分析了两组之间的比例差异及其 95％置信区间。
结果
在过去一年中进行过性行为的 583 名活跃的男性学生中，有 128 名和 455 名是 MSM 和 MSW。与 MSW 学生相比，更多的 MSM 学生表示知道男男性行为是中国学生中 HIV 传播的主要途径（62.5％比 45.5％），同意进行商业性行为（67.2％比 53.4％），希望在发生随意性行为之前了解伴侣的 HIV 状况（65.8％比 51.3％），感到感染 HIV 的风险（40.5％比 11.8％）， condom-decision 量表得分较高（55.3％比 42.6％），与≥5 名随意性伴侣发生性行为（44.6％比 25.9％），在网上寻找随意性伴侣（89.2％比 51.3％），在发生随意性行为之前饮酒（64.8％比 45.0％），与固定伴侣发生性行为（83.1％比 67.0％），从事商业性行为（54.2％比 26.4％），以及主动寻求自愿咨询和检测（VCT）服务（16.4％比 8.4％）。但是，与 MSW 学生相比，较小比例的 MSM 学生报告知道坚持使用安全套可以预防 HIV 传播（80.5％比 95.2％），并且在发生危险性行为后应积极寻求 VCT（78.9％比 93.8％），有时/经常使用安全套（26.4％比 44.3％），并且在与随意性伴侣发生性行为时始终使用安全套（28.9％比 40.1％）。
结论
与 MSW 学生相比，发生随意性行为的 MSM 学生 HIV/STI 传播的风险更高。需要针对无保护的男男性行为，在线寻找随意性伴侣以及不使用 HIV 检测服务的风险进行综合干预，以降低该亚组 MSM 中的 HIV/STI 传播负担。
