Despite the development of targeted interventions for men who have sex with men, this population continues to comprise the majority of new HIV diagnoses. Though condoms are highly efficacious, some sexually active MSM use sero-sorting as a method of HIV prevention. This study aimed to characterize: (1) differences between partner sero-status and condom use likelihood, and (2) demographic, behavioral, and knowledge-related factors influencing condom use likelihood with varying sero-status partners. Using convenience sampling, 150 sexual and gender minority men completed a survey on PrEP and sexual behaviors. The majority of participants identified as racial/ethnic minorities (51.7%), having 4 years of college or more (52.0%), and being HIV-negative (not on PrEP) (68.8%). Our sample reported the lowest average condom use likelihood with a partner on PrEP (2.93 ± 1.39) and the highest average likelihood with an HIV-positive partner (unknown VL) (4.57 ± 0.98). Age, race/ethnicity, education, HIV-status, and HIV and PrEP knowledge were significantly associated with differences in condom use likelihood. Our findings elucidate the complexity of sero-sorting scenarios and decision-making processes in the context of biomedical HIV prevention. These results may provide insight for future condom use and sero-sorting interventions in the context of biomedical HIV prevention.
尽管针对男男性行为者(MSM)已经开发了靶向干预措施,但该人群仍然是新诊断出的 HIV 病例的主要人群。虽然避孕套的效果非常显著,但一些活跃的男男性行为者会选择血清学筛选作为 HIV 预防方法。本研究旨在描述:(1)伴侣血清学状态和使用避孕套可能性之间的差异;(2)影响与不同血清学状态伴侣发生性行为时使用避孕套可能性的人口统计学、行为和知识相关因素。本研究采用便利抽样方法,对 150 名性和性别少数群体男性进行了关于 PrEP 和性行为的调查。大多数参与者被认定为种族/少数民族(51.7%),拥有大学或以上学历(52.0%),并且是 HIV 阴性(未接受 PrEP)(68.8%)。我们的样本报告与接受 PrEP 的伴侣发生性行为时使用避孕套的可能性最低(2.93±1.39),与 HIV 阳性(未知病毒载量)伴侣发生性行为时使用避孕套的可能性最高(4.57±0.98)。年龄、种族/民族、教育程度、HIV 状态以及 HIV 和 PrEP 知识与使用避孕套的可能性差异显著相关。我们的研究结果阐明了在生物医学 HIV 预防背景下血清学筛选场景和决策过程的复杂性。这些结果可能为未来在生物医学 HIV 预防背景下开展关于避孕套使用和血清学筛选的干预措施提供参考。
