目的了解男男性行为者(MSM)群体的艾滋病病毒/性病(HIV/STD)感染水平。方法在MSM聚集的酒吧,在知情同意下,匿名填写问卷,自愿选择检查项目,在现场开展体检和实验室标本采集,标本按要求冷藏转送至实验室。结果共检测了144人,平均年龄32.68岁,未婚者占59.03%,各种文化层次和职业者均有。他们中只有同性性行为者占38.64%,其他人均与异性有性行为。首次性行为的平均年龄为20.82岁。近3个月内被调查者有与异性的性行为及各种方式的性行为,且每次使用安全套者仅13.77%。其中11.11%的人报告曾被诊断有性病。现场体检发现尖锐湿疣患病率13.21%(14/106)。尿道分泌物检查淋球菌阳性率2.68%(3/112),沙眼衣原体8.04%(9/112),解脲脲原体25.00%(28/112),生殖支原体4.46%(5/112)。血清学检查HIV抗体全部阴性,梅毒螺旋体明胶凝集试验(TPPA)阳性率18.75%(27/144),快速血浆反应素试验(RPR)阳性率9.72%(14/144),疱疹病毒抗体(HSV-2-IgG)阳性率7.78%(7/90),乙型肝炎病毒表面抗原(HBsAg)阳性率9.68%(9/93),丙型肝炎病毒抗体(抗-HCV)阳性率0(0/93),戊型肝炎病毒抗体(抗-HEV)阳性率16.13%(15/93)。结论MSM人群的性生活状态复杂并且缺乏安全性意识,成为HIV/STD传播的桥梁人群。他们中STD的感染水平较一般人群高,个别感染甚至接近性病门诊的感染水平,应该引起关注。
Objectives To understand HIV / STD prevalence among men who have sex with men (MSM). Methods At the bar where the MSM gathered, with the informed consent, the questionnaire was filled in anonymously and the project was voluntarily selected. Physical examination and laboratory specimen collection were conducted on site. The specimens were refrigerated and transferred to the laboratory as required. Results A total of 144 persons were detected, with an average age of 32.68 years and 59.03% of unmarried people. There were all kinds of cultural levels and professionals. Among them, only homosexuals account for 38.64% of the total, while others have sex with the opposite sex. The average age of first sex is 20.82 years. In the past 3 months, the respondents had heterosexual sex and various forms of sexual behavior, and only 13.77% of them used condoms each time. 11.11% of them reported having been diagnosed with STD. The physical examination found that the prevalence of genital warts was 13.21% (14/106). Neisseria gonorrhoeae positive rate of 2.68% (3/112), Chlamydia trachomatis 8.04% (9/112), Ureaplasma urealyticum 25.00% (28/112), Mycoplasma genitalium 4.46% (5/112). The positive rate of TPPA was 18.75% (27/144), the positive rate of RPR was 9.72% (14/144), the herpes simplex virus (HSV- The positive rate of hepatitis B virus surface antigen (HBsAg) was 9.68% (9/93) and that of hepatitis C virus (anti-HCV) was 0 (0/93) ). The positive rate of hepatitis E virus antibody (anti-HEV) was 16.13% (15/93). Conclusion The MSM population has complicated sex life and lack of safety awareness, which has become a bridge of HIV / STD transmission. Among them, the infection level of STD is higher than that of the general population, and individual infection should be closely concerned with the infection level of STD clinics.
