Recent increases in rates of unprotected anal sex (UAS) among men who have sex with men (MSM) signal the need to continually refine our understanding of factors associated with risky sexual behavior. Data were collected using a questionnaire eliciting information about the last sexual episode (LSE) with another man in the past 6 months. Logistic regression was used to identify both event-level and background correlates of UAS at LSE. 965 participants who reported having sex with a partner with whom they were not in a couple relationship at LSE were studied. Several event-level variables were significantly associated with UAS after adjusting for background factors, including finding the partner at LSE sexually attractive and using alcohol or cocaine at LSE. Our findings parallel the results of other HIV prevention studies which have highlighted the importance of interpersonal factors that influence risk-taking at the moment of a sexual act among MSM.
最近，男男性行为者（MSM）中非保护性肛交（UAS）的比例有所上升，这表明我们需要不断深化对与危险性行为相关因素的理解。数据是通过问卷调查收集的，该问卷询问了过去 6 个月内与另一名男性的最后一次性行为（LSE）的信息。逻辑回归用于确定 LSE 时 UAS 的事件水平和背景相关性。研究了 965 名报告在 LSE 与非伴侣关系的伴侣发生性行为的参与者。在调整背景因素后，包括在 LSE 时发现伴侣具有性吸引力以及在 LSE 时使用酒精或可卡因，几个事件水平变量与 UAS 显著相关。我们的研究结果与其他 HIV 预防研究的结果相似，这些研究强调了影响 MSM 在性行为时刻冒险行为的人际因素的重要性。
