Recent increases in the availability of pre-exposure prophylaxis (PrEP) internationally have widened the range of HIV prevention strategies available to gay and bisexual men. This paper aimed to quantify the use of different risk reduction strategies and compare characteristics of men who rarely use any strategies with those who regularly use condoms or PrEP. Using national cross-sectional data from the Gay Community Periodic Surveys in Australia, comparisons were made between regular condom users (37.1% of participants), PrEP users (50.1%), and men who infrequently used any risk reduction strategies (12.8%). The proportion of gay and bisexual men reporting infrequent use of HIV risk reduction strategies has decreased in recent years. These men reported less frequent high-risk sexual practices than PrEP users and also reported less recent HIV testing than either PrEP or condom users. Men who infrequently use HIV risk reduction strategies should be encouraged to test for HIV more regularly and to utilise prevention strategies that align with their infrequent high-risk behaviour.

在国际上，接触前预防措施（PrEP）的可利用性最近在国际上有所增加，从而扩大了男同性恋者和双性恋者可用的艾滋病毒预防策略的范围。本文旨在量化使用不同的降低风险策略，并将很少使用任何策略的男性与经常使用安全套或PrEP的男性的特征进行比较。使用来自澳大利亚同性恋社区定期调查的国家横截面数据，对定期使用避孕套的使用者（占参与者的37.1％），使用PrEP的使用者（占50.1％）和不经常使用任何降低风险策略的男性（占12.8％）进行了比较。近年来，报告不经常使用降低艾滋病毒风险的策略的男同性恋和双性恋男人的比例有所下降。这些男性报告的高危性行为频率低于使用PrEP的用户，并且报告的近期HIV检测率也低于PrEP或安全套用户。应鼓励不经常使用降低HIV风险策略的男性更定期地进行HIV检测，并采用与其不常见的高风险行为相适应的预防策略。
