摘　　要：目的探讨年轻男男性接触者（MsM）社会网络与艾滋病高危行为的关系，为开展社会网络干预提供依据。方法采用应答者驱动方法在安徽合肥市招募研究对象，共有193名符合条件的男男性接触者接受面对面问卷调查。调查内容主要包括社会人口学特征、最近6个月性伴数、性行为，个体核心社会网络等。结果在个体近6个月肛交性伴数≥2个的预测模型中，若核心社会网络成员中女性成员达到半数及以上，报告肛交性伴数≥2个的危险性是核心网络成员均为男性的0．174倍（95％a=0．043～0．705），若核心社会网络成员中大学及以上文化达到及超过半数者，报告肛交性伴数≥2个的危险性是核心社会网络成员中大学及以上文化程度未达到半数者的0．472倍（95％a=0．236～0．947）。若核心社会网络成员全都支持调查对象的性取向，报告肛交性伴数≥2个的危险性为核心社会网络成员不全支持者的2．141倍（95％a=1．128～4．065）；在个体近6个月无保护肛交（UAI）预测模型中。若核心社会网络成员均知道调查对象性取向、调查对象与核心社会网络成员间无性关系，报告UAI的危险性分别是调查对象性取向在其核心社会网络成员不全公开者的1．955倍（95％a=1．071～3．716）、调查对象与核心社会网络成员间有性关系者的0．239倍（95％a=0．126～0．454）。结论社会网络是艾滋病危险行为扩散的重要影响因素，社会网络是当前遏制艾滋病在MSM人群中扩散的重要资源和途径。Objective To analyze characteristics of the core social network and the roles as influencing factors on HIV - risk behaviors and to provide basis for HIV/STDs intervention among young men who have sex with men（MSM）. Methods 193 eligible MSM were recruited to participate in the study by using Respondent Driven Sampling（RDS） in Hefei, Anhui, China. All were interviewed by face to face. Variables included social demographic characteristics, number of homosexual partners and sexual behaviors during the previous six months, the egocentric networks were constructed by linking together named 1 to 5 primary network members（namely, the core social networks）. Results It was found that in predictive models of MSM who had at least 2 anal sexual partners in the past 6 months： （1）MSM whose core social networks consisted of women（ 50 % ） showed that odds ratio was 0.174（95 % confidence interval：0. 043 to 0. 705） in comparison with those MSM whose core social networks only consisted of men. （2）Proportion of the MSM＇s network members received college education reach to 50 % or higher, those MSM showed that the odds ratio was 0. 472 （95 % CI = 0. 236- 0. 947） in comparison with counterpart. （3）MSM whose network members fully supported his sex - orientation showed that the odds ratio was 2. 141 （95 % CI = 1.128 - 4. 065 ） in comparison with counterpart. In the UAI predictive models during the previous 6 months： （1）MSM whose sex-orientation was fully open to his network members showed that the odds ratio was 1. 955 （95 % CI = 1. 071 3. 716） in comparison with counterpart. （2）MSM who didn＇t have sex with his social network members showed that the odds ratio was 0.239 （95 % CI = 0.126 - 0. 454 ） in comparison with counterpart. Conclusion Social networks played an important role in dissemination of HIV - risk behaviors. This emphasizes the importance of using social networks approaches, which are the potential resources, to control HIV among young men who have sex with m
