山东省男男性行为者安全套使用及影响因素分析

Condom use and its influence factors among men who have sex with men in Shandong province

目的分析山东省男男性行为者(MSM)人群性行为安全套使用情况及影响因素,为制定针对性的防治措施提供依据。方法于2010年4—7月采用面对面的匿名问卷调查方法,在MSM人群中收集有效问卷3 086份,采集血液标本3 073份,采用酶联免疫吸附法和免疫印迹法对血清样本进行艾滋病病毒(HIV)抗体、梅毒抗体检测。结果 2 254名MSM最近6个月与同性发生过肛交性行为,占73.0%(2 254/3 086),731人坚持每次都使用安全套,占32.4%;704名MSM最近半年与异性发生过性行为,占22.8%(701/3 086),161人坚持每次都使用安全套,占22.9%(161/704);多因素logistic回归分析结果表明,低档场所(浴池/桑拿/足疗/按摩、公园/公厕/草地)、年龄较大、在本地居住时间较长是MSM发生同性肛交性行为时不坚持使用安全套的独立影响因素,而学历较高是MSM发生同性肛交性行为时坚持使用安全套的独立影响因素;低档场所、网络招募、年龄较大、在本地居住时间较长、外省户籍是MSM发生异性性行为时不坚持使用安全套的独立影响因素,而未婚是MSM发生异性性行为时坚持使用安全套的独立影响因素。结论山东省MSM安全套使用率较低;场所、年龄、婚姻状况、学历、在本地居住时间、户籍等是山东省MSM安全套使用的主要影响因素。

Objective To analyze the condom use and its influence factors among men who have sex with men（MSM） in Shandong province and to provide scientific evidence for making specific behavioral intervention.Methods Face-to-face anonymous questionnaire survey was implemented in 3 086 MSM in 2010.Serum samples were collected and antibodies of human immunodeficiency virus（HIV） and syphilis were tested by enzyme-linked immunosorbent assay（ELISA） and western blotting.Results During the past half year,73.0%（2 254/3 086）of the MSM had anal intercourse with men and 32.4% of them used condom persistently.Multivariate logistic regression analyses showed that the independent influence factors of risk sex behavior were small venues（bathroom,sauna shop,pedicure shop,massage parlors,and park/toilet/ grass）,older age,and living longer in a local place;higher level of education was independent factor enhancing persistent condom use.Besides,22.8%（701/3 086）of MSM had sex with women and 22.9%（161/704） of them used condom persistently.The independent factors increasing the risk sex behavior were small venues and net recruiting,older age,living longer in a local place,and foreign census register;unmarried was an independent factor enhancing persistent condom use.Conclusion The rate of condom use is low and venues,marriage,age,education level,time of living in local place,and census register are main influence factors of using condom among MSM in Shandong province.
