HIV prevention efforts, particularly among men who have sex with men (MSM), have not achieved maximum effectiveness. A survey of MSM in Ottawa, Canada was completed to ascertain whether there were differences in how the perceived HIV status of participants and their partners influenced sexual practices.
Self-directed surveys were administered to a convenience sample of 721 MSM in Ottawa, Canada from November 2011 through May 2012. Data collection occurred at 14 sites. The survey identified whether participants identified as HIV positive, negative or unsure of their HIV status.
The findings indicated variation between HIV-negative MSM and those who are unsure of their HIV status. Men who were unsure of their HIV status were less likely to report that they asked sexual partners or have had their partners ask about HIV status.
The results of this study indicate that some MSM may base decisions about HIV prevention on discussion about HIV status with their partners, rather than condom use. These practices may increase, rather than decrease, HIV transmission. Survey findings and extant literature demonstrate a need to inform MSM about the limitations of serosorting as a prevention strategy, and to provide facilitated access to sexually transmitted infection testing and treatment to further reduce onward HIV transmission.
艾滋病毒预防工作,尤其是在男男性行为者(MSM)中,尚未达到最大效果。对加拿大渥太华的男男性行为者进行了一项调查,以确定参与者及其伴侣对艾滋病毒状况的认知如何影响性行为方面是否存在差异。
2011年11月至2012年5月,对加拿大渥太华721名男男性行为者的便利样本进行了自我管理的调查。数据收集在14个地点进行。该调查确定了参与者是否将自己认定为艾滋病毒阳性、阴性或不确定自己的艾滋病毒状况。
研究结果表明,艾滋病毒阴性的男男性行为者与那些不确定自己艾滋病毒状况的人之间存在差异。不确定自己艾滋病毒状况的男性不太可能报告他们询问性伴侣或让伴侣询问艾滋病毒状况。
本研究结果表明,一些男男性行为者可能会根据与伴侣关于艾滋病毒状况的讨论而非使用避孕套来做出艾滋病毒预防决策。这些行为可能会增加而非减少艾滋病毒传播。调查结果和现有文献表明,有必要告知男男性行为者血清分类作为预防策略的局限性,并提供便利的性传播感染检测和治疗途径,以进一步减少艾滋病毒的传播。
