Social network composition is known to effect patterns of reported sexual risk-taking among men who have sex with men (MSM); however, consensus as to the directionality and size of these effects is lacking. We examined the relationships between novel aspects of social network composition and sexual risk-taking using a cross-sectional survey of 870 MSM. Social network composition was found to have mixed effects on reported sexual risk-taking: reporting proportionally more lesbian, gay, or bisexual (LGB)-identified friends and reporting friends who were on average significantly older than the respondent were both associated with reporting increased sexual risk, while reporting proportionally more LGB-identified friends in relationships and reporting a social network proportionally more aware of the respondent's homosexuality/bisexuality were both associated with reporting decreased sexual risk. The support structures created by differing social network compositions-and particularly the presence of LGB couples-may be a potential area for targeting sexual risk-reduction interventions for MSM.
众所周知，社交网络构成会影响男男性行为者（MSM）报告的性冒险行为模式；然而，对于这些影响的方向性和程度尚未达成共识。我们通过对870名男男性行为者进行横断面调查，研究了社交网络构成的新方面与性冒险行为之间的关系。结果发现，社交网络构成对报告的性冒险行为有混合影响：报告中女同性恋、男同性恋或双性恋（LGB）身份的朋友比例较高，以及报告平均年龄明显大于受访者的朋友，都与报告的性风险增加有关，而报告中处于恋爱关系的LGB身份朋友比例较高，以及报告社交网络中对受访者的同性恋/双性恋身份了解程度较高的比例，都与报告的性风险降低有关。不同社交网络构成所形成的支持结构——尤其是LGB伴侣的存在——可能是针对男男性行为者开展性风险降低干预措施的一个潜在目标领域。
