We investigated the hypothesis that gay and bisexual men experiencing stressful life events are more likely to engage in risky sexual behavior. Data were from a cohort study of 155 HIV-positive and 207 HIV-negative men in Ontario, Canada (1998-2007). We quantified the relation between stressful life events and unprotected anal intercourse with a non-regular partner. In the past 6 months, 19% reported unprotected intercourse (HIV+: 28%; HIV-: 13%) and 58% reported one or more stressful life events (HIV+: 64%; HIV-: 55%). Among HIV-negative men, the odds of unprotected intercourse increased by 1.15 for each additional event (95%CI 1.06, 1.24). Among HIV-positive men, those who reported the event "problems due to alcohol or drugs" were 1.80 (95%CI 1.27, 2.56) times more likely to report unprotected intercourse. Interventions to assist men to cope with stress may help to prevent population spread of HIV and improve overall health.
我们研究了这样一个假设，即经历压力生活事件的男同性恋和双性恋者更有可能进行危险的性行为。数据来自于加拿大安大略省的一项队列研究，涉及 155 名 HIV 阳性和 207 名 HIV 阴性男性（1998-2007 年）。我们量化了压力生活事件与与非固定性伴侣发生无保护肛交之间的关系。在过去的 6 个月中，19%的人报告了无保护性行为（HIV+：28%；HIV-：13%），58%的人报告了一个或多个压力生活事件（HIV+：64%；HIV-：55%）。在 HIV 阴性男性中，每增加一个事件，无保护性行为的几率增加 1.15（95%CI 1.06，1.24）。在 HIV 阳性男性中，报告“因酒精或毒品导致的问题”这一事件的人报告无保护性行为的可能性是 HIV 阴性男性的 1.80 倍（95%CI 1.27，2.56）。干预措施以帮助男性应对压力，可能有助于防止 HIV 在人群中的传播，并改善整体健康状况。
