The rates of HIV/syphilis infections and associated factors among male patients in sexually transmitted disease clinics in Tianjin,2012

目的了解性病门诊男性就诊者中，艾滋病病毒（HIV）、梅毒（SP）的感染状况及危险因素，为在该人群中开展相关防控措施提供依据。方法对天津市2家性病门诊中符合条件的男性就诊者开展问卷调查，同时抽取血样检测梅毒和HIV抗体。结果800例性病门诊男性就诊者中，HIV抗体阳性16例，阳性率为2．0％。多因素分析表明，最近3个月有同性性行为[比值比（OR）=21．642，95％可信区间（CI）：7．211～64．946]、感染梅毒（OR=3．097，95％CI：1．059～9．055）与HIV感染关系有统计学意义。梅毒阳性129例，阳性率为16．1％。多因素分析表明，最近3个月有商业性行为（OR=6．306，95％CI：3．930～10．118）、最近3个月有同性性行为（OR=5．948，95％CI：3．017～11．725）与梅毒感染关系有统计学意义。结论性病门诊男性就诊者HIV、梅毒感染率较高，危险行为普遍存在，急需采取有效措施来控制性病艾滋病的传播蔓延。

Objective To understand the rate of HIV/ syphilis infections and their associated factors, so as to provide a reference for prevention of HIV/STDs. Methods A cross-sectional survey was conducted in male outpa- tients of 2 STD clinics in Tianjin. Blood samples were collected to test HIV/syphilis. Results The rate of HIV in- fection was 2.0% among 800 male outpatients. Multivariate logistic regression analysis showed that the factors aso- ciated with HIV infection among male outpatients included having homosexual behaviors last three months （OR= 21. 642, 95%CI：7. 211-64. 946）, syphilis infection （OR= 3. 097, 95%CI： 1. 059-9.055）. The rate of syphilis infection was 16.1%. Multivariate logistic regression analysis showed that the associated factors included having commercial sex last three months （OR=6. 306, 95%CI： 3. 930-10. 118）, having homosexual behaviors last three months （OR-5. 948, 95%CI： 3. 017-11. 725）.
