Pre-exposure prophylaxis (PrEP) has shown promise as a safe and effective HIV prevention strategy, but there is limited research on awareness and use among young men who have sex with men (YMSM). Using baseline data from the "Keep It Up! 2.0" randomized control trial, we examined differences in PrEP awareness and use among racially diverse YMSM (N = 759; mean age = 24.2 years). Participants were recruited from study sites in Atlanta, Chicago, and New York City, as well as through national advertising on social media applications. While 67.5 % of participants reported awareness of PrEP, 8.7 % indicated using the medication. Awareness, but not use, varied by demographic variables. PrEP-users had twice as many condomless anal sex partners (ERR = 2.05) and more condomless anal sex acts (ERR = 1.60) than non-users. Future research should aim to improve PrEP awareness and uptake among YMSM and address condom use.
暴露前预防（PrEP）已显示出作为一种安全有效的艾滋病毒预防策略的前景，但关于男男性行为者（YMSM）对其的知晓率和使用率的研究有限。利用“坚持下去！2.0”随机对照试验的基线数据，我们研究了不同种族的男男性行为者（N = 759；平均年龄 = 24.2岁）在PrEP知晓率和使用率方面的差异。参与者是从亚特兰大、芝加哥和纽约市的研究地点招募的，也通过社交媒体应用上的全国性广告招募。虽然67.5%的参与者报告知晓PrEP，但8.7%的人表示使用过该药物。知晓率因人口统计学变量而异，但使用率并非如此。与未使用者相比，PrEP使用者的无保护肛交伴侣数量（ERR = 2.05）和无保护肛交行为更多（ERR = 1.60）。未来的研究应旨在提高男男性行为者对PrEP的知晓率和接受率，并解决避孕套的使用问题。
