HIV risk perception plays a crucial role in the uptake of preventive strategies. We investigated how risk perception and its determinants changed between 1999 and 2018 in an open, prospective cohort of 1323 HIV-negative men who have sex with men (MSM). Risk perception, defined as the perceived likelihood of acquiring HIV in the past 6 months, changed over time: being relatively lower in 2008-2011, higher in 2012-2016, and again lower in 2017-2018. Irrespective of calendar year, condomless anal intercourse (AI) with casual partners and high numbers of partners were associated with higher risk perception. In 2017-2018, condomless receptive AI with a partner living with HIV was no longer associated with risk perception, while PrEP use and condomless AI with a steady partner were associated with lower risk perception. We showed that risk perception has fluctuated among MSM in the past 20 years. The Undetectable equals Untransmittable statement and PrEP coincided with lower perceived risk.
HIV 风险感知在预防策略的采用中起着至关重要的作用。我们调查了在 1999 年至 2018 年间，在一个开放的、前瞻性队列中，1323 名 HIV 阴性的男男性行为者（MSM）中，风险感知及其决定因素是如何变化的。风险感知被定义为过去 6 个月内感染 HIV 的可能性，它随时间发生了变化：在 2008-2011 年相对较低，在 2012-2016 年较高，而在 2017-2018 年再次降低。无论在哪个日历年内，与偶然伴侣发生无保护肛交（AI）和性伴侣数量多与更高的风险感知相关。在 2017-2018 年，与 HIV 感染者发生无保护的接受 AI 不再与风险感知相关，而 PrEP 的使用和与稳定伴侣发生无保护 AI 与较低的风险感知相关。我们表明，在过去的 20 年中，MSM 的风险感知一直在波动。“检测不到等于无法传播”和 PrEP 的出现与较低的感知风险相关。
