The Centers for Disease Control and Prevention recommends at least annual HIV testing for men who have sex with men (MSM), but motivations for testing are not well understood.
We evaluated data from MSM testing for HIV at a community-based program in King County, Washington. Correlates of regular testing were examined using generalized estimating equation regression models.
Between February 2004 and June 2011, 7176 MSM attended 12,109 HIV testing visits. When asked reasons for testing, 49% reported that it was time for their regular test, 27% reported unprotected sex, 24% were starting relationships, 21% reported sex with someone new, 21% sought sexually transmitted infection/hepatitis screening, 12% reported sex with an HIV-infected partner, 2% suspected primary HIV infection, and 16% reported other reasons. In multivariable analysis, factors associated with regular testing included having a regular health care provider and the following in the previous year: having only male partners, having 10 or more male partners, inhaled nitrite use, not injecting drugs, and not having unprotected anal intercourse with a partner of unknown/discordant status (P ≤ 0.001 for all). Men reporting regular testing reported shorter intertest intervals than men who did not (median of 233 vs. 322 days, respectively; P < 0.001).
Regular testing, sexual risk, and new partnerships were important drivers of HIV testing among MSM, and regular testing was associated with increased testing frequency. Promoting regular testing may reduce the time that HIV-infected MSM are unaware of their status, particularly among those who have sex with men and women or inject drugs.
疾病控制与预防中心建议男男性行为者（MSM）至少每年进行一次 HIV 检测，但人们对检测的动机了解甚少。
我们评估了华盛顿州金县一个社区为基础的项目中 MSM 进行 HIV 检测的数据。使用广义估计方程回归模型来检查定期检测的相关性。
在 2004 年 2 月至 2011 年 6 月期间，7176 名 MSM 参加了 12109 次 HIV 检测。当被问及检测的原因时，49%的人报告说这是他们定期检测的时间，27%的人报告说有过无保护措施的性行为，24%的人开始了新的关系，21%的人报告与新的性伴侣发生了性行为，21%的人寻求性传播感染/肝炎筛查，12%的人报告与 HIV 感染的伴侣发生了性行为，2%的人怀疑是原发性 HIV 感染，16%的人报告了其他原因。在多变量分析中，与定期检测相关的因素包括有一个常规的医疗服务提供者和在过去一年中：只有男性伴侣，有 10 个或更多的男性伴侣，吸入亚硝酸酯，不注射毒品，与不知道/不一致的伴侣没有无保护的肛交（所有 P ≤ 0.001）。报告定期检测的男性比不报告定期检测的男性报告的检测间隔更短（中位数分别为 233 天和 322 天，P < 0.001）。
定期检测、性风险和新的伴侣关系是 MSM 进行 HIV 检测的重要驱动因素，而定期检测与增加检测频率有关。促进定期检测可能会减少 HIV 感染的 MSM 不知道自己的状况的时间，特别是那些与男性和女性发生性行为或注射毒品的人。
