| 目的 了解2016－2018年天津市MSM人群HIV感染状况及其相关因素。方法 按照全国艾滋病哨点监测方案要求，采用横断面调查方法，于2016－2018年4－6月，连续监测并收集天津市MSM人群的艾滋病知识知晓率、相关性行为、以及HIV、梅毒、HCV感染等信息，各年样本量400人。结果 2016－2018年天津市监测MSM共1 200人，最近6个月同性肛交坚持使用安全套的比例为45.4%（544/1 198），网络招募的MSM既往接受过HIV检测的比例呈现下降的趋势（趋势χ2=42.742，P<0.001）。HIV感染率为3.3%（40/1 200），HIV-1新发感染率为2.6%（95% CI：1.7%～3.5%），梅毒感染率为6.7%（80/1 200），HCV感染率为0.8%（9/1 200）。多因素logistic回归分析结果显示，离异或丧偶（与未婚者相比，aOR=7.137，95% CI：1.621～31.419）、梅毒抗体阳性（与梅毒抗体阴性者相比，aOR=3.684，95% CI：1.520～8.932）是MSM人群感染HIV的危险因素；最近6个月同性肛交坚持使用安全套（与不坚持使用安全套者相比，aOR=0.343，95% CI：0.126～0.932）、既往检测过HIV抗体（与既往未检测HIV抗体者相比，aOR=0.314，95% CI：0.123～0.801）是MSM人群感染HIV的保护因素。结论 2016－2018年天津市MSM人群的HIV感染率较高，梅毒感染风险不容忽视，同性肛交坚持使用安全套的比例较低，应该采取有效措施促进MSM坚持使用安全套和定期检测HIV抗体。 |

| Objective To understand the HIV infection status and related factors in men who have sex with men (MSM) in Tianjin during 2016-2018. Methods According to the sentinel surveillance protocol, continuous cross-sectional studies were conducted to collect the information about the awareness of AIDS, related behaviors, HIV infection, syphilis prevalence and HCV infection in the MSM in Tianjin with the annual sample seize of 400 between April and June during 2016-2018. Results From 2016 to 2018, a total of 1 200 MSM were surveyed. The condom use rate in anal sex was 45.4% (544/1 198) in the past 6 months. The HIV test rate in MSM recruited through network declined with year (trend χ2=42.742, P<0.001). The overall HIV infection rate was 3.3% (40/1 200). The HIV-1 infection rate was 2.6% (95%CI:1.7%-3.5%). The overall prevalence rate of syphilis was 6.7% (80/1 200). The overall HCV infection rate was 0.8% (9/1 200). Results from multivariate logistic regression analysis showed that the risk factors associated with HIV infection in the MSM included divorced or widowed (compared with unmarried, aOR=7.137, 95%CI:1.621-31.419) and syphilis positive group (compared with syphilis negative group, aOR=3.684, 95%CI:1.520-8.932). The protective factors for HIV infection in the MSM included consistent use of condom in the past 6 months (compared with occasional use of condom, aOR=0.343, 95%CI:0.126-0.932) and HIV test (compared with receiving no HIV test, aOR=0.314, 95%CI:0.123-0.801). Conclusions The HIV infection rate in the MSM in Tianjin was high from 2016 to 2018. Syphilis prevalence status in MSM should not be neglected. The rate of consistent condom use in anal sex was low in the MSM. It is necessary to take effective measures to promote condom use and strengthen HIV test in MSM. |
