摘要/Abstract

摘要： 目的了解天津市西青区中老年（≥45岁）男男性行为者（men who sexual with men,MSM）行为特征以及免疫缺陷病毒（human immunodeficiency virus,HIV）感染的影响因素,为提出针对性的预防和干预措施提供参考依据。方法对2021年1月—2024年10月参与天津市西青区高危人群专项调查的≥45岁的MSM人群开展一对一问卷调查和HIV检测,并对数据进行分析。结果共调查334人,HIV阳性率为4.49%。82.04%的调查对象3个月内性伴数量为1~5人;47.60%的受检者在3个月内坚持使用安全套;调查对象在最近1次性行为中安全套的使用率为45.81%。多因素分析结果显示,年龄≥50岁是感染HIV的危险因素,其HIV感染风险是45~<50岁的调查对象的3.74倍（OR=3.74,95%CI：1.08~13.00,P<0.05）;3个月内性伴数量≥6人是感染HIV的危险因素,其HIV感染风险是性伴数量为0人的调查对象的10.81倍（OR=10.81,95%CI：1.01~115.41,P<0.05）;3个月内性行为不使用安全套是感染HIV的危险因素,其HIV感染风险是3个月内坚持使用安全套的受检者的15.04倍（OR=15.04,95%CI：3.00~73.68,P<0.01）。结论 ≥45岁的MSM人群感染HIV的危险因素包括年龄≥50岁、多性伴和无保护性行为,该人群已成为天津市西青区艾滋病干预工作的重点,应加强对其的宣传教育和干预检测,提高安全套使用率,有效降低中老年MSM人群的HIV感染风险。

Abstract: Objective To understand behavior characteristics of men who sexual with men（MSM） aged ≥45 years old in Xiqing District of Tianjin,explore the influencing factors of human immunodeficiency virus（HIV） infection,and provide reference for proposing targeted prevention and intervention measures. Methods A one-on-one questionnaire survey and HIV testing were conducted among MSM population aged≥45 years old who had participated in the special survey of high-risk population in Xiqing District from January 2021 to October 2024,and the data were analyzed. Results A total of 334 people were recruited with the HIV positive rate of 4.49%. 82.04% subjects had 1~5 sexual partners within three months. 47.60% subjects had consistently used condoms in the past three months. The condom use rate was 45.81% during the most recent sexual intercourse. The multivariate analysis showed that aged ≥50 years old was the risk factor of HIV infection,and their HIV infection risk was 3.74 times higher than that of survey respondents aged 45-<50（OR=3.74,95%CI：1.08-13.00,P<0.05）. The subjects having at least six homosexual partners within three months was the risk factor of HIV infection,and their HIV infection risk was 10.81 times higher than that of subjects had 0 partners（OR=10.81,95%CI：1.01-115.41,P<0.05）. The subjects did not use condoms during sexual activity within three months was the risk factor for HIV infection,and their HIV infection risk was 15.04 times higher than that of subjects consistently used condoms within three months（OR=15.04,95%CI：3.00-73.68,P<0.01）. Conclusions The risk factors for HIV infection in MSM population aged ≥45 years old include age ≥50 years old,multiple sexual partners and unprotected sex. This population has become the focus of AIDS intervention in Xiqing District. It is necessary to strengthen publicity,education and intervention testing among them,and improve the condom use rate,so as to effectively reduce the risk of HIV infection among middle-aged and elderly MSM population.
