We used an Internet-based questionnaire to investigate whether viewing pornography depicting unprotected anal intercourse (UAI) was associated with engaging in UAI in a sample of 821 non-monogamous men who have sex with men (MSM). In the 3 months prior to interview, 77.2% viewed pornography depicting UAI, 42.6% engaged in insertive UAI, and 38.9% engaged in receptive UAI. Polytomous logistic regression of the 751 subjects who provided data on pornography viewing showed significantly elevated odds ratios for having engaged in receptive UAI, insertive UAI, and both receptive and insertive UAI associated with increasing percentage of pornography viewed that depicted UAI. We also found independently significant associations of engaging in UAI with age, use of inhalant nitrites, and HIV status. Although the data cannot establish causality, our findings indicate that viewing pornography depicting UAI and engaging in UAI are correlated. Further research is needed to determine if this observation may have utility for HIV prevention.
我们采用基于互联网的问卷，对 821 名非单一性伴侣的男男性行为者（MSM）进行了调查，以探究观看未行保护措施的肛交性行为（UAI）相关色情制品是否与 UAI 行为有关。在访谈前的 3 个月内，77.2%的参与者观看了 UAI 相关色情制品，42.6%的参与者有过插入式 UAI 行为，38.9%的参与者有过接受式 UAI 行为。对 751 名提供了色情制品观看数据的参与者进行多元逻辑回归分析，结果显示，观看 UAI 相关色情制品的比例越高，接受式 UAI、插入式 UAI 以及两者兼有的发生风险比也随之升高。我们还发现，与 UAI 行为相关的因素包括年龄、使用吸入性亚硝酸酯类药物和 HIV 感染状况。尽管这些数据无法确定因果关系，但我们的研究结果表明，观看 UAI 相关色情制品和 UAI 行为之间存在相关性。还需要进一步的研究来确定这一观察结果是否可以为 HIV 预防提供帮助。
