Health in Men (HIM) was an open cohort study of 1,427 HIV-negative homosexual men in Sydney. The majority of respondents' unprotected anal intercourse (UAIC) events were with partners whose HIV status they did not know. Nonetheless, with casual partners with whom they engaged in UAIC, respondents indicated that they knew 'well' 28.9% of the HIV-negative partners and 26.2% of HIV-positive partners, but only 7.6% of the HIV status unknown partners. Respondents were more likely to have engaged in UAIC with partners they knew well (McNemar P < 0.001). The challenge for HIV prevention is that many gay men's decisions about condom use may be driven as much by their relationship with individual partners as their commitment to 'safe sex'.
男性健康研究（HIM）是一项针对悉尼 1427 名 HIV 阴性同性恋男性的开放性队列研究。大多数受访者的无保护肛交（UAIC）事件涉及他们不知道 HIV 状况的伴侣。尽管如此，在与他们发生 UAIC 的偶然伴侣中，受访者表示，他们“很了解”28.9%的 HIV 阴性伴侣和 26.2%的 HIV 阳性伴侣，但仅了解 7.6%的 HIV 状况未知的伴侣。受访者更有可能与他们“很了解”的伴侣发生 UAIC（McNemar P < 0.001）。HIV 预防的挑战在于，许多男同性恋者关于使用避孕套的决定可能更多地受到他们与个别伴侣关系的驱动，而不是他们对“安全性行为”的承诺。
