在美国，与男性发生性关系的黑人男性（BMSM）的艾滋病毒感染率最高。尽管越来越多地注意到社会和性网络作为生物医学干预的框架，但家庭在这些网络中的作用及其与艾滋病毒预防的关系受到的关注有限。通过对BMSM（n=204）及其家庭成员（n=176）的问卷调查和个人网络的启发，获得了BMSM及其家庭成员的网络样本（N=380）。计算个人网络的比例，家庭和加权逻辑回归被用来评估这一比例与无保护的肛交（UAI），性药物使用（SDU）和群体性行为（GS）之间的关系，以及干预措施，以阻止这些危险行为之间的MSM社交网络。45.3%的受访者在其亲密的个人网络中列出了至少一名家庭成员。较大的家庭网络比例（在紧密网络中有2个或更多家庭成员）与较小的SDU [校正比值比（AOR 0.38（0.17-0.87））]和参与GS（AOR 0.25（0.10-0.67））相关。在干预方面，家庭比例大的BMSM更可能在其MSM朋友网络中阻止GS（AOR 3.83（1.56-9.43））和SDU（AOR 2.18（1.35-3.54））。此外，男性家庭网络比例增加与较低的艾滋病毒风险和更大的干预比女性网络比例增加。近一半的BMSM有一个亲密的家庭成员与他们分享个人信息。如果将个人网络中这一经常被忽视的组成部分纳入其中，综合预防干预措施可能会更加有效。
Black men who have sex with men (BMSM) have the highest rates of HIV in the United States. Despite increased attention to social and sexual networks as a framework for biomedical intervention, the role of family in these networks and their relationship to HIV prevention has received limited attention. A network sample (N=380) of BMSM (n=204) and their family members (n=176) was generated through respondent driven sampling of BMSM and elicitation of their personal networks. The proportion of personal networks that were family was calculated and weighted logistic regression was used to assess the relationship between this proportion and unprotected anal intercourse (UAI), sex-drug use (SDU) and group sex (GS); as well as intravention efforts to discourage these risk behaviors among their MSM social networks. 45.3% of respondents listed at least one family member in their close personal network. Greater family network proportion (having 2 or more family members in the close network) was associated with less SDU [adjusted odds ratio (AOR 0.38(0.17–0.87))] and participation in GS (AOR 0.25(0.10–0.67)). For intravention, BMSM with greater family proportion were more likely to discourage GS (AOR 3.83(1.56–9.43) and SDU (AOR 2.18(1.35–3.54)) among their MSM friend network. Moreover, increased male family network proportion was associated with lower HIV-risk and greater intravention than increased female network proportion. Nearly half of BMSM have a close family member with whom they share personal information. Combination prevention interventions might be made more potent if this often overlooked component of personal networks were incorporated.
