HIV diagnoses among men who have sex with men (MSM) have been increasing in several high-income countries. A better understanding of the sexual behavior trends among MSM can be useful for informing HIV prevention. We conducted a systematic review of studies that examined behavioral trends (1990-2013) in any condomless anal sex, condomless anal sex with an HIV-discordant partner, and number of partners. Studies included come from the United States, Europe, and Australia. We found increasing trends in condomless anal sex and condomless anal sex with an HIV-discordant partner, and a decreasing trend in number of partners. The increase in condomless anal sex may help to explain the increase in HIV infections. More explanatory research is needed to provide insight into factors that contribute to these behavior trends. Continuous monitoring of HIV, risk behaviors, and use of prevention and treatment is needed to evaluate prevention efforts and monitor HIV transmission risk.
在几个高收入国家,男男性行为者(MSM)中的艾滋病毒诊断病例一直在增加。更好地了解男男性行为者的性行为趋势有助于为艾滋病毒预防工作提供信息。我们对研究男男性行为者无保护肛交、与艾滋病毒抗体不一致伴侣进行无保护肛交以及性伴侣数量等行为趋势(1990年至2013年)的研究进行了系统综述。纳入的研究来自美国、欧洲和澳大利亚。我们发现,无保护肛交以及与艾滋病毒抗体不一致伴侣进行无保护肛交呈上升趋势,而性伴侣数量呈下降趋势。无保护肛交的增加可能有助于解释艾滋病毒感染病例的增加。需要开展更多解释性研究,以深入了解导致这些行为趋势的因素。需要持续监测艾滋病毒、风险行为以及预防和治疗措施的使用情况,以评估预防工作并监测艾滋病毒传播风险。
