HIV among men who have sex with men (MSM) with recent male-male sexual debut, such as within the past 5 years, may be a proxy for recent HIV infection. Using this definition, we explored factors associated with HIV infection in this group to understand the evolving HIV epidemic among MSM in Chongqing. We conducted a cross-sectional respondent-driven sampling survey among Chongqing MSM in 2011. Computer-assisted, self-administered questionnaires were used and blood specimens were collected for HIV and syphilis testing. Three hundred and ninety-one unique MSM were recruited of which 65.7 % (257) had their sexual debut with another man in the past 5 years. HIV prevalence among men with recent sexual debut was 18.7 % suggesting a possible HIV incidence of 3.7 %. Multivariable analysis among men with recent sexual debut suggests that lower education, having more than one male partner, and currently being infected with syphilis are associated with HIV among men with recent sexual debut. HIV prevalence is high among MSM with recent sexual debut in Chongqing, which may be a proxy a high incidence rate. HIV prevention efforts should focus on STD reduction among those MSM with lower educational attainment.
在男男性行为者（MSM）中，那些最近（如过去5年内）开始男男性行为的人感染艾滋病毒的情况，可能是近期艾滋病毒感染的一个代表指标。利用这一定义,我们探究了该群体中与艾滋病毒感染有关的因素，以便了解重庆男男性行为者中不断演变的艾滋病毒流行情况。2011年，我们在重庆的男男性行为者中开展了一项横断面应答者驱动抽样调查。采用计算机辅助的自填问卷方式，并采集血样进行艾滋病毒及梅毒检测。共招募了391名不同的男男性行为者,其中65.7%（即257人）在过去5年内首次与其男性伴侣发生性行为,近期首次发生性行为的男性中艾滋病毒感染率达,这表明艾滋病毒发病率可能为3.7%。近期首次发生性行为的男性的多变量分析表明，文化程度较低,有不止一位男性伴侣，以及目前感染梅毒，与近期首次发生性行为的男性感染艾滋病毒有关联。在重庆，近期首次发生性行为的男男性行为者中艾滋病毒感染率较高，这可能意味着发病率较高,艾滋病毒预防工作应侧重于教育程度较低的男男性行为者中减少性传播感染。
