摘　　要：目的了解湖北省MSM人群HIV新发感染率及其动态变化情况。方法将2010—2013年湖北省MSM哨点监测1I438例样本纳入研究，对HIV-1抗体确证阳性样本采用BED捕获酶联免疫方法（BED．CEIA）进行HIV新发感染检测，估算该人群连续4年的新发感染率；汇总2010--2013年的调查数据，对不同年龄组、不同样本来源和不同地区的新发感染率以及安全套使用率进行分层分析。结果2010—2013年湖北省MSMHIV阳性率分别为3．34％、3．74％、2．96％和3．15％，HIV新发感染率分别为2-31％、1．91％、1．53％和1．71％。汇总2010--2013年的调查数据，≤30岁年龄组MSM的HIV阳性率低于〉30岁年龄组、HIV新发感染率高于〉30岁年龄组；不同样本来源的HIV新发感染率有差异，HIV新发感染率最高的人群分别来自工作组／疾病预防控制中心和浴室，分别为3．54％和3．49％；武汉、襄阳、荆州和黄石地区HIV新发感染率分别为5．73％、3．37％、1．51％和1．50％；MSM最近6个月坚持使用安全套的比例为38．91％。多因素分析显示，样本来源（OR=O．344—0．713）、地区（OR=3．581。9．577）、安全套的使用（OR=6．686）是HIV新发感染的影响因素。结论湖北省MSM艾滋病流行水平总体稳定在较高水平，且安全套使用率较低，局部地区新发感染率处于较高水平，应采取有效措施加以控制。Objective To understand the HIV infection status among MSM in Hubei province and provide scientific evidence for the development of intervention strategy. Methods A total of 11 438 samples were collected from MSM in sentinel surveillance during 2010-2013 to detect HIV-1 antibody. BED-CEIA was used to identify the recent HIV infection, and the recent HIV infection rate among the MSM was estimated. The age, group and area specific recent infection rate and condom use rate were analyzed. Results The annual HIV positive rates among MSM were 3.34%, 3.74%, 2.96% and 3.15% respectively and the annual recent infection rates were 2.31%, 1.91%, 1.53% and 1.71% respectively during 2010-2013. The HIV positive rate in age group ~〈30 years was lower than that in age group 〉 30 years, but the recent HIV incidence rate was higher in age group ≤30 years than in age group 〉30 years. The detection rate of recent HIV infection varied with sample source, the highest detection rate was among the samples form work group/CDC and public bathroom（3.54% and 3.49%, respectively）. The recent HIV infection rate in Wuhan was highest （5.73%）. The proportion of MSM using condoms in each homosexual behavior during past six months was 38.91%. Multiple logistic regression analysis indicated that the factors related to recent HIV infection included sample source （OR=0.344-0.713） , area （OR=3.581-9.577） and condom usage（OR=6.686）. Conclusion The HIV-1 infection rate in MSM was at a high level in Hubei, especially in some areas. The condom use rate was low, it is necessary to strengthen the prevention and control of HIV infection in MSM.
