To increase understanding of the HIV epidemic among MSM in Barcelona, anonymous questionnaires were completed by 640 MSM recruited in the city in 2002. The prevalence of unprotected anal intercourse (UAI) with casual male partners in the prior 12 months was higher among self-reported HIV-positive men (confirmed through saliva testing) than among men who were HIV-negative or of unknown serostatus (35% vs. 20%, p < .01). The prevalence of UAI with steady male partners was substantially lower among HIV-positive men than other men (28% vs. 60%, p < .01). In multivariate analyses, UAI with casual partners was more likely among HIV-positive individuals; those who used drugs before sex; perceived less acceptance of their sexual orientation by family, friends, or coworkers; and were less concerned about HIV prevention because of antiretroviral therapy (ART). UAI with steady partners was more likely among HIV-negative men with seroconcordant partners, those living with a partner, and men less concerned about HIV prevention because of ART. Findings indicate a need for prevention programs targeting HIV-positive MSM in Barcelona. Attention to substance use and attitudes about HIV prevention are needed for MSM in general.
为了增进对巴塞罗那男男性行为者中艾滋病毒流行情况的了解，2002年在该市招募了640名男男性行为者，他们填写了匿名调查问卷。在过去12个月中，自我报告为艾滋病毒阳性的男性（通过唾液检测确诊）与临时性男性伴侣发生无保护肛交（UAI）的比例高于艾滋病毒阴性或血清学状态不明的男性（35%对20%，p<.01）。艾滋病毒阳性男性与固定男性伴侣发生无保护肛交的比例显著低于其他男性（28%对60%，p<.01）。在多变量分析中，艾滋病毒阳性个体、性行为前使用毒品的人、感觉家人、朋友或同事对其性取向接受程度较低的人以及因抗逆转录病毒疗法（ART）而对艾滋病毒预防关注度较低的人，更有可能与临时性伴侣发生无保护肛交。艾滋病毒阴性且伴侣血清学一致的男性、与伴侣同居的男性以及因抗逆转录病毒疗法而对艾滋病毒预防关注度较低的男性，更有可能与固定伴侣发生无保护肛交。研究结果表明，巴塞罗那需要针对艾滋病毒阳性男男性行为者开展预防项目。一般而言，男男性行为者需要关注物质使用情况以及对艾滋病毒预防的态度。
