目的：比较年轻男同性恋者和双性恋者中HIV感染风险行为的流行率和预测因子，这些人认为自己是HIV阴性、HIV阳性或未经检测。采用多阶段概率抽样法，在旧金山弗朗西斯科招募并采访了408名18-29岁的男同性恋和双性恋男子，并从364名参与者中采集了用于HIV检测的血液样本。艾滋病毒感染率为18.7%，但25%的艾滋病毒阳性男子不知道这一点，37%的人报告在过去一年中进行了无保护的肛交，其中59%的男子知道自己是艾滋病毒阳性，35%的男性认为自己艾滋病毒呈阴性，28%的未经检测的男性。Logistic回归发现类似的艾滋病毒阴性和艾滋病毒阳性，包括性冲动，物质使用，性享受和沟通problems.Conclusions的无保护性交的预测因素：高利率的无保护性交，特别是在艾滋病毒阳性的男性，证明了年轻的男同性恋和双性恋男性艾滋病毒预防干预的迫切需要。研究结果表明，艾滋病毒阳性和阴性男子在干预措施中针对的许多重要变量是相似的。
Objectives: To compare the prevalence and predictors of HIV sexual risk behavior among young gay and bisexual men who perceived themselves to be HIV-negative, HIV-positive, or who were untested.Design: Population-based sample of young gay and bisexual men.Methods: Using multi-stage probability sampling, 408 gay and bisexual men aged 18-29 years in San Francisco were recruited and interviewed, and blood samples for HIV-testing from 364 participants were obtained.Results: HIV prevalence was 18.7%, although 25% of the men who were HIV-positive did not know it. Thirty-seven per cent reported engaging in unprotected anal intercourse during the past year, including 59% of the men who knew they were HIV-positive, 35% of the men who perceived themselves HIV-negative and 28% of the untested men. Logistic regressions found similar predictors of unprotected intercourse for HIV-negatives and HIV-positives, including sexual impulsivity, substance use, sexual enjoyment and communication problems.Conclusions: The high rates of unprotected intercourse, particularly among the HIV-positive men, attest to the urgent need for HIV-prevention interventions for young gay and bisexual men. The findings suggest that many of the important variables to target in interventions are similar for both HIV-positive and HIV-negative men.
