男男性行为者网络活动及网络性伴相关社会行为特征研究

Research on the Network Activities of MSM and Characteristics of the Related Social Behavior of the Network Sexual Partners

目的了解男男性行为者(men who have sex with men,MSM)人群网络活动及相关因素。方法采用滚雪球抽样法,在固定场所进行MSM人群的招募和寻问式匿名问卷调查。结果在调查的400人中,87.8%常参与MSM相关互联网活动,网络活动目的41.9%为寻找性伴、31.9%为放松心理、14.5%为交友;认为网络对自己行为影响很大、较大分别为27.1%、27.9%,认为较小、很小分别为4.6%、2.5%;51.0%以网络进入MSM圈子,69.0%以网络寻找性伴。网络性伴平均年龄为(24.8±6.4)岁,低于其他性伴类型的(36.1±13.5)岁(t′=-7.808,P=0.000),年龄越小、文化程度越高网络性伴比例越大(χ2趋势=106.322、68.398,P均<0.01),学生及干部职员/其他职业、未婚、同性性取向者网络性伴较高(P均<0.01)。认识当地MSM朋友数≥6,近6月性伴居住城市数≥2,知晓HIV知识,来自咨询服务、来自互联网者网络性伴比例较多,HIV知识信息来自朋友者较少(P均<0.05)。首次性行为年龄越小、累计男性固定性伴数越多、近1周肛交次数越少者网络性伴比例越大(χ2趋势=15.903、32.802、13.583,P均<0.01);首次性行为对象为男性,近6月性伴数≤3、有男性固定性伴、有保护性主动肛交、有保护性被动肛交者网络性伴比例较大,有女性性行为、有女性固定性伴者网络性伴较少(P均<0.05)。结论 MSM网络活动极为普遍,网络对HIV防治的正面效应和负面作用互显,应针对性探索和加大更适合网络活动MSM特性的网络干预。

Objective To understand the network activities of men who have sex with men（MSM） and the related factors.Methods The MSM were recruited by snowball sampling at a fixed place.An anonymous questionnaire survey was conducted and related information was asked.Results Among the 400 MSM surveyed,87.8% often participated in the MSM network activities.As to the purposes,41.9% were for looking for sexual partners,31.9% for mental relaxation and 14.5% for making friends.The impacts of the network activities on their behaviors,as they thought,were various,and the respondents who thought the network activities had very large,large,small and very small impacts on their behavior accounted for 27.1%,27.9%,4.6% and 2.5%,respectively.Through the internet,51.0% of them stepped into the MSM circle and 69.0% sought for sexual partners.The average age of network sexual partners was（24.8±6.4） years,which was significantly younger than that of the sexual partners sought for by other routes（36.1±13.5 years,t’=-7.808,P=0.000）.The younger the MSM were,or the higher education they got,the more likely they were to look for sexual partners by internet（χ2trend=106.322,68.398 respectively,both P0.01）.Besides,among the MSM who had occupation as students or cadres/staff/other occupations who were unmarried,and who has homosexual orientations,the proportions of those having network partners were higher（all P0.01）.The respondents who knew six or more local MSM friends,whose sexual partners lived in at least two cities in the recent six months,who knew HIV prevention and control knowledge,who acquired HIV knowledge and information from consulting services or from internet,were more likely to have network sexual partners,while those who acquired HIV knowledge and information from friends were less likely（all P0.05）.The younger they were when they had first sexual behavior,the more regular male partners in accumulation they had,or the less they had anal sex in the recent one week,the more likely they were to have sexual partners（χ2trend=15.903,32.802,13.583,all P0.01）.The respondents who had first sex with men,who,in the recent six months,had at most 3 sexual partners,had regular male sexual partners,or had protective initiative or passiveanal sex,were more likely to have network sexual partners,while those who,in the recent six months,had female sexual behaviors or fixed female sexual partners were less likely to have（all P0.05）.Conclusions Network activities are popular among MSM.The internet has both positive and negative effects on HIV prevention and control.It should be targeted to explore and enhance network intervention that is more compatible with the characteristics of network activities of MSM.
