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 have 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 network members who were family was calculated, and the weighted logistic regression was used to assess the relationship between this proportion and unprotected anal intercourse, 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 1 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, 95% CI: 0.17 to 0.87] and participation in GS (AOR 0.25, 95% CI: 0.10 to 0.67). For intravention, BMSM with greater family proportion were more likely to discourage GS (AOR 3.83, 95% CI: 1.56 to 9.43) and SDU (AOR 2.18, 95% CI: 1.35 to 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 was incorporated.
在美国，与男性发生性关系的黑人男性（BMSM）的 HIV 感染率最高。尽管越来越关注社交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 HIV 预防的关系受到的关注有限。
通过对 BMSM 进行回应驱动抽样和个人网络的启发，生成了一个 BMSM 网络样本（N=380）（n=204）和他们的家庭成员（n=176）。计算个人网络成员中家庭成员的比例，并使用加权逻辑回归评估该比例与无保护肛交、性毒品使用（SDU）和群交（GS）的关系，以及干预措施劝阻这些风险行为在他们的 MSM 社交网络中。
45.3%的受访者在他们的亲密个人网络中列出了至少 1 个家庭成员。更大的家庭网络比例（亲密网络中有 2 个或更多家庭成员）与较少的 SDU 相关[调整后的优势比（AOR）0.38，95%可信区间：0.17 至 0.87]和参与 GS（AOR 0.25，95%可信区间：0.10 至 0.67）。对于干预措施，具有更大家庭比例的 BMSM 更有可能劝阻他们的 MSM 朋友网络中的 GS（AOR 3.83，95%可信区间：1.56 至 9.43）和 SDU（AOR 2.18，95%可信区间：1.35 至 3.54）。此外，男性家庭网络比例的增加与 HIV 风险降低和干预增加有关，而女性网络比例的增加则不然。
近一半的 BMSM 与他们分享个人信息的亲密家庭成员。如果将个人网络中经常被忽视的这一组成部分纳入其中，综合预防干预措施可能会更有效。
