Objective: To explore the HIV epidemic and related factors among MSM in Jilin province. Methods: During the implementation of sentinel surveillance program from 2010 to 2015, continuous cross-sectional studies were conducted to monitor the awareness of AIDS, sexual behavior, HIV and syphilis positive rates, with the sample size no less than 400 in each surveillance site. Results: From 2010 to 2015, a total of 7 823 MSM were involved in this study. The overall HIV prevalence among MSM was 5.4% (42/7 823), with an increasing trend during 2010 and 2015 (Trend test χ(2)=110.023, P<0.001). The rates of awareness on AIDS were higher than 90.0%. The proportion of consistent condom use was 27.0% (2 112/7 823) in the last 6 months, and significant differences were found in these years (χ(2)=234.038, P<0.001). Results from multivariate logistic regression analysis showed that the HIV infection related risk factors among MSM in Jilin province would include: residency from other provinces (aOR=1.797, 95%CI: 1.185-2.726), recruitment through internet (aOR=1.717, 95%CI: 1.332-2.215), diagnosed of having sexually transmitted diseases in the previous year (aOR=1.893, 95%CI: 1.356-2.643) and positive testing on syphilis (aOR=4.309, 95%CI: 3.097-5.995). And consistent condom uses in the last 6 months (aOR=0.387, 95%CI: 0.143-0.557), tested HIV in the last year (aOR=0.632, 95%CI: 0.375-0.891) were preventive factors. Conclusions: HIV prevalence was increasing among MSM in Jilin province, but both the proportion of consistent condom use and the former HIV testing rate were at a low level. Aggressive measurement including consistent condom use and periodical HIV testing among MSM was warranted.
目的： 了解吉林省MSM人群HIV的感染状况及其相关因素。 方法： 2010－2015年，根据《全国艾滋病哨点监测方案》的要求，在艾滋病哨点监测期内，通过横断面调查的方法对吉林省MSM艾滋病知识知晓率、性行为状况、HIV和梅毒抗体阳性率水平等进行连续监测，每个监测哨点样本量≥400人。 结果： 2010－2015年吉林省共监测MSM 7 823人，HIV感染率为5.4%（42/7 823），HIV感染率呈逐年上升趋势（趋势χ(2)=110.023，P<0.001）。2010－2015年，MSM艾滋病知识知晓率均>90.0%。最近6个月坚持使用安全套的比例为27.0%（2 112/7 823），不同年份的差异有统计学意义（χ(2)=234.038，P<0.001）。多因素logistic回归分析结果显示，MSM感染HIV的可能危险因素包括外省户籍（aOR=1.797，95%CI：1.185~2.726）、网络招募（aOR=1.717，95%CI：1.332~2.215）、最近1年曾诊断过性病（aOR=1.893，95%CI：1.356~2.643）和梅毒抗体阳性（aOR=4.309，95%CI：3.097~5.995）；可能保护性因素包括最近6个月同性性行为坚持使用安全套（aOR=0.387，95%CI：0.143~0.557）、最近1年曾检测过HIV（aOR=0.632，95%CI：0.375~0.891）。 结论： 2010－2015年吉林省MSM人群HIV感染率呈上升趋势，坚持使用安全套的比例和HIV检测率均较低，应采取有效措施促进MSM定期做HIV检测和坚持使用安全套。.
