Pre‐exposure prophylaxis (PrEP) is a key HIV prevention technology, and is a pillar of a comprehensive HIV prevention approach for men who have sex with men (MSM). Because there have been no national data to characterize trends in the PrEP continuum in the United States, overall and for key demographic groups of MSM, we aimed to describe the extent to which PrEP awareness, willingness and use changed over time, overall and for specific groups of MSM critical for HIV prevention (e.g. Black and Hispanic MSM, younger MSM, MSM in rural areas and MSM without health coverage).

2013 年至 2017 年在线招募的美国男男性行为者中艾滋病毒暴露前预防意识、意愿和使用情况的全国趋势


暴露前预防（PrEP）是一项关键的艾滋病毒预防技术，也是男男性行为者（MSM）艾滋病毒综合预防方法的支柱。由于没有国家数据来描述美国 PrEP 连续体的总体趋势和 MSM 关键人口群体的趋势，因此我们旨在描述 PrEP 意识、意愿和使用随时间变化的程度，总体和具体情况对艾滋病毒预防至关重要的 MSM 群体（例如黑人和西班牙裔 MSM、年轻 MSM、农村地区 MSM 以及没有医疗保险的 MSM）。
