This study aimed to describe sexually explicit online media (SEOM) consumption among men who have sex with men (MSM) in the United States and examine associations between exposure to unprotected anal intercourse (UAI) in SEOM and engagement in both UAI and serodiscordant UAI. MSM in the U.S. who accessed a men-seeking-men website in the past year (N = 1,170) were recruited online for a cross-sectional, Internet-based survey of sexual risk and SEOM consumption. In the 3 months prior to interview, more than half (57 %) of the men reported viewing SEOM one or more times per day and almost half (45 %) reported that at least half of the SEOM they viewed portrayed UAI. Compared to participants who reported that 0-24 % of the SEOM they viewed showed UAI, participants who reported that 25-49, 50-74, or 75-100 % of the SEOM they viewed portrayed UAI had progressively increasing odds of engaging in UAI and serodiscordant UAI in the past 3 months. As SEOM has become more ubiquitous and accessible, research should examine causal relations between SEOM consumption and sexual risk-taking among MSM as well as ways to use SEOM for HIV prevention.
本研究旨在描述美国男男性行为者（MSM）对色情网络媒体（SEOM）的消费情况，并探讨接触 SEOM 中的无保护肛交（UAI）与参与 UAI 和血清不一致 UAI 之间的关联。过去一年中访问过男男性接触者网站的美国 MSM 通过在线方式招募，参与了一项关于性风险和 SEOM 消费的横断面、基于互联网的调查。在访谈前的 3 个月内，超过一半（57%）的男性报告每天观看一次或多次 SEOM，近一半（45%）的男性报告至少有一半观看的 SEOM 描绘了 UAI。与报告 0-24%的 SEOM 描绘 UAI 的参与者相比，报告 25-49%、50-74%或 75-100%的 SEOM 描绘 UAI 的参与者在过去 3 个月中进行 UAI 和血清不一致 UAI 的可能性逐渐增加。随着 SEOM 的普及和可访问性，研究应该检验 MSM 中 SEOM 消费与性冒险之间的因果关系，以及利用 SEOM 进行 HIV 预防的方法。
