Increasing serostatus awareness is a key HIV prevention strategy. Despite expanded testing efforts, some men who have sex with men (MSM) remain unaware of their HIV status. This study explored demographic characteristics, sexual identity, sexual role, and behavioral factors associated with unknown HIV status among MSM in the United States. Data from 9170 MSM in the 2014 American Men's Internet Survey were analyzed using logistic regression to identify correlates of unknown HIV status. Young age, race, low education, rural residence, and lack of recent healthcare visits were significantly associated with unknown HIV status. In addition, nondisclosure of one's sexual orientation (OR = 3.70, 95% CI 2.99-4.59) and a self-identified sexual role as "bottom" (OR = 1.45, 95% CI 1.24-1.70) were predictors of unknown HIV status. Post-hoc analysis showed HIV-negative MSM not tested in the last year had fewer self-reported risk behaviors than recent testers, suggesting that repeat testing among MSM may be aligned with individual risk.
提高血清阳性检出意识是预防艾滋病的关键策略。尽管扩大了检测力度，但一些男男性行为者（MSM）仍不知道自己的艾滋病毒感染状况。本研究探讨了美国 MSM 中与 HIV 感染状况未知相关的人口统计学特征、性身份、性行为角色和行为因素。使用逻辑回归对来自 2014 年美国男性互联网调查的 9170 名 MSM 的数据进行分析，以确定 HIV 感染状况未知的相关因素。年龄较小、种族、教育程度较低、农村居住和最近没有接受医疗保健服务是 HIV 感染状况未知的显著相关因素。此外，性取向不公开（OR=3.70，95%CI 2.99-4.59）和自我认同的性行为角色为“受方”（OR=1.45，95%CI 1.24-1.70）是 HIV 感染状况未知的预测因素。事后分析表明，过去一年未接受检测的 HIV 阴性 MSM 自我报告的风险行为比最近接受检测的 MSM 少，这表明 MSM 中可能需要重复检测以符合个人风险。
