We examined the hypothesis that black and Latino men who have sex with men (MSM) who have supportive social relationships with other people are less likely to have unrecognized HIV infection compared with MSM of color who report lower levels of social support. We interviewed 1286 black and Latino MSM without known HIV infection in three metropolitan areas who were recruited using respondent driven sampling. Participants completed a computer-administered questionnaire and were tested for HIV. Unrecognized HIV infection was found in 118 men (9.2%). MSM who scored higher on the supportive relationship index had significantly lower odds of testing HIV-positive in the study. The mediation analysis identified two possible behavioral pathways that may partially explain this association: men who had strong supportive relationships were more likely to have had a test for HIV infection in the past 2 years and less likely to have recently engaged in high-risk sexual behavior. The findings illuminate the protective role of social relationships among MSM of color in our sample.
我们检验了这样一个假设，即与报告社会支持水平较低的有色人种男男性行为者（MSM）相比，与他人建立支持性关系的黑人和拉丁裔 MSM 不太可能感染未被发现的 HIV。我们在三个大都市地区使用应答者驱动抽样法招募了 1286 名没有已知 HIV 感染的黑人和拉丁裔 MSM 进行了采访。参与者完成了计算机管理的问卷调查并接受了 HIV 检测。在研究中，发现有 118 名男性（9.2%）感染了未被识别的 HIV。在支持关系指数上得分较高的 MSM 感染 HIV 的几率明显较低。中介分析确定了两个可能的行为途径，这些途径可能部分解释了这种关联：与支持性关系牢固的男性更有可能在过去 2 年内接受 HIV 感染检测，而最近从事高危性行为的可能性较低。这些发现阐明了在我们的样本中，社会关系对有色人种 MSM 的保护作用。
