南京市男男性行为人群HIV性伴检测影响因素的1∶2配比分析

Factors associated with HIV couple testing among men who have sex with men in Nanjing:a 1∶2 matching analysis

目的:研究影响男男性行为(men who have sex with men,MSM)人群进行人类免疫缺陷病毒(human immunodeficiency virus,HIV)性伴检测的因素,为制定MSM人群性伴HIV检测策略提供依据。方法:采用1∶2配比分析方法,性伴检测组为江苏省疾病预防控制中心2017年5—10月在南京市开展的MSM人群艾滋病预防干预研究中筛选出做过性伴检测者,对照为同期调查未做过性伴检测者,并且对年龄(±5岁)、性取向以及婚姻状况进行匹配。问卷自行设计,对人口学、行为学等信息采用网络调查的方式。数据先经过Excel进行筛选,再采用logistic回归模型进行单因素和多因素分析。结果:调查中共有73例做过性伴检测,匹配146例未做性伴检测者作为对照。单因素分析显示既往HIV检测次数(χ2=6.195,P<0.05)、既往HIV自我检测次数(χ2=33.658,P<0.05)和性角色为"0"(χ2=5.223,P<0.05)与性伴检测存在统计学意义。多因素分析显示既往HIV自我检测次数(OR=8.502,95%CI:3.474～20.805)和性角色为"0"(OR=0.397,95%CI:0.163～0.969)有统计学意义。结论:既往HIV自我检测次数是性伴检测的促进因素,性角色为"0"是性伴检测的阻碍因素。

Objective:This study aimed to study the factors influencing the human immunodeficiency virus(HIV)couple testing among men who have sex with men(MSM),to provide the basis for formulating HIV couple testing strategies for MSM population.Method:①A 1∶2 matching analysis was conducted among MSM who did couple testing identified at the survey on AIDS prevention and intervention in Nanjing from May to October in 2017,and the control group was among the people who did not do the couple testing in the same survey of the same period of time. Each case was matched by age(±5),sexual orientation and marital status.②The questionnaire design was based on the information of demography and behavioristics,using network survey.③The data was screened by Excel first,then the logistic regression model is used for univariate and multivariate analysis. Results:A total of 73 patients were tested for sexual partners,while 146 subjects were matched in the control group. Univariate analysis showed that the number of previous HIV tests(χ2=6.195,P<0.05),the number of previous HIV self-testing(χ2=33.658,P<0.05)and the sex role of"0"(χ2=5.223,P<0.05)had statistical significance with the sexual partner test. Multivariate analysis showed that the number of HIV self-testing in the past(OR=8.502,95%CI:3.474,20.805)and the sex role of"0"(OR=0.397,95%CI:0.163,0.969)were statistically significant. Conclusion:The number of HIV self-testing in the past was the promoting factor of couple testing,and the sex role of"0"was the obstacle factor for the testing.
