本研究的目的是确定预测故意使用的艾滋病毒的风险降低的做法，血清分选，战略定位，并退出射精前无保护肛交（UAI）与临时合作伙伴。2007年，在与其他男性发生性关系的男性（MSM）中进行了一项关于瑞士艾滋病毒行为监测系统的横断面调查，使用匿名自填问卷。分析仅限于有临时伴侣的UAI参与者（N = 410）。Logistic回归分析用于评估与有意使用血清分选、战略定位和射精前戒断相关的因素。在过去的12个月里，71%的参与者报告与不同或未知艾滋病毒状态的临时伴侣发生UAI。其中，47%的人报告了实践戒断，38%的人报告了血清分选，25%的人报告了战略定位。在319名已知HIV状态的参与者中，血清分选与过去12个月内频繁使用互联网寻找伴侣（OR = 2.32），STI（OR = 2.07）和HIV检测（OR = 1.81）相关。策略定位与HIV状态（OR = 0.13）和与不同或未知HIV状态的伴侣发生UAI（OR = 3.57）相关。HIV阴性参与者或报告大量性伴侣（OR = 2.48）和与未知或不同血清状态的伴侣发生UAI（OR = 2.08）的参与者更经常退出。男男性行为者广泛采用减少风险的做法，每种做法都有其自身的特点。需要进一步研究，以确定减少危害做法的背景因素，特别是其使用的战略或机会主义性质。
The aim of this study was to identify predictors of intentional use of the HIV risk reduction practices of serosorting, strategic positioning, and withdrawal before ejaculation during unprotected anal intercourse (UAI) with casual partners. A cross-sectional survey pertaining to the Swiss HIV behavioral surveillance system, using an anonymous self-administered questionnaire, was conducted in 2007 in a self-selected sample of men having sex with other men (MSM). Analysis was restricted to participants with UAI with casual partner(s) (N = 410). Logistic regression was used to estimate factors associated with intentional use of serosorting, strategic positioning, and withdrawal before ejaculation. In the previous 12 months, 71% of participants reported having UAI with a casual partner of different or unknown HIV-status. Of these, 47% reported practicing withdrawal, 38% serosorting, and 25% strategic positioning. In the 319 participants with known HIV-status, serosorting was associated with frequent Internet use to find partners (OR = 2.32), STI (OR = 2.07), and HIV testing in the past 12 months (OR = 1.81). Strategic positioning was associated with HIV-status (OR = 0.13) and having UAI with a partner of different or unknown HIV-status (OR = 3.57). Withdrawal was more frequently practiced by HIV-negative participants or participants reporting high numbers of sexual partners (OR = 2.48) and having UAI with a partner of unknown or different serostatus (OR = 2.08). Risk reduction practices are widely used by MSM, each practice having its own specificities. Further research is needed to determine the contextual factors surrounding harm reduction practices, particularly the strategic or opportunistic nature of their use.
