男男性行为人群兼有异性性行为特征及HIV感染现状调查

Investigation and analysis of heterosexual sexual behavior and HIV infection among men

目的了解男男性行为人群兼有异性性行为特征及人体免疫缺损病毒(HIV)感染现状。方法根据2017年1月至2019年1月枣庄市艾滋病流行病学调查及哨点监测资料,选取本市常住的≥18周岁及近1年内有同性性行为史的男性为调查对象。面对面匿名问卷调查收集年龄、受教育程度、婚姻状况等资料,抽取外周静脉血进行HIV抗体、梅毒抗体的血清学检测。结果本研究调查的278例男男性行为人群中发生异性性行为45例(16.19%)。受教育程度、婚姻状况、月收入水平、性取向、是否通过网络寻找性伴侣、首次性行为对象性别在兼有异性性行为与无异性性行为人群之间比较差异均有统计学意义(均P<0.05)。多因素Logistic回归分析显示,受教育程度、婚姻状况、月收入水平、性取向、首次性行为对象性别是男男性行为人群兼有异性性行为的独立影响因素(均P<0.05)。本研究调查的278例男男性行为人群中HIV感染31例(11.15%),梅毒感染18例(6.47%);其中HIV与梅毒同时感染14例(5.04%),近1年患过性病42例(15.11%)。兼有异性性行为人群中梅毒阳性率明显高于无异性性行为人群,差异有统计学意义(P<0.01)。结论本市男男性行为人群中兼有异性性行为的比例处于较低水平,HIV感染率处于较高水平,应给予针对性防控。

Objective To understand the characteristics of heterosexual behavior and the status of human immunodeficiency virus(HIV) infection in men.Methods According to the data of AIDS epidemiological survey and sentinel surveillance in Zaozhuang City from January 2017 to June 2019, the male who lived in the city, aged 18 years and over, and had the same-sex sexual behavior history in the past year were selected as the objects of investigation. Anonymous face-to-face questionnaire was used to collect age, education, marital status and other data, and peripheral venous blood was collected for serological detection of HIV antibody and syphilis antibody.Results 45(16.19%) of 278 men had heterosexual behaviors. There were significant differences in education level, marital status, monthly income level, sexual orientation, whether to find sexual partners through the Internet, and the gender of the first sexual object between the group with and without heterosexual sexual behavior(P<0.05). Education level, marriage status, monthly income level, sexual orientation, gender of the first sexual object were the independent influencing factors of male behavior group with heterosexual sexual behavior. Among 278 men, 31(11.15%) had HIV infection and 18(6.47%) had syphilis infection. The positive rate of syphilis in the group with heterosexual behavior was significantly higher than that in the group without heterosexual behavior(P<0.01). There was no significant difference between the two groups in the proportion of HIV positive, HIV with syphilis and having had sexual disease in the past year(P<0.01).Conclusion The proportion of heterosexual sexual behaviors in the male behavior population is at a low level, and the HIV infection rate is at a high level.
