目的对济南市男男性行为梅毒和人类免疫缺陷病毒(HIV)感染状况及其相关的因素进行调查,从而为男男性接触者(MSM)人群高危行为干预提供科学依据。方法使用同伴推动抽样法(RDS)进行匿名问卷调查,共调查500人,采集血液样品500份,用RDS分析软件(RDSAT)及SPSS 15.0分析软件进行统计学分析。结果共调查男男性接触人群500人,HIV阳性检测率为3.1%(95%CI:1.3~5.1)。梅毒感染率7.0%(95%CI:4.9~9.2),自我评估为男性性取向占46.3%(95%CI:41.3~51.5),HIV和梅毒合并感染率0.7%。结论MSM人群梅毒感染比较严重,因此要加大在该人群中的性病防治干预,提高其HIV/STD感染危险性意识,促进其安全性行为方式。
Objective To investigate the status of syphilis and human immunodeficiency virus (HIV) infection in men who have sex with men (MSM) in Jinan and the related factors, so as to provide a scientific basis for high-risk behavior intervention in MSM. Methods Peer survey (RDS) was used to conduct anonymous questionnaire survey. A total of 500 people were investigated. 500 blood samples were collected and analyzed by RDS analysis software and SPSS 15.0 analysis software. Results A total of 500 men who had sex with men were surveyed. The HIV positive rate was 3.1% (95% CI: 1.3-5.1). The prevalence of syphilis was 7.0% (95% CI: 4.9-9.2), 46.3% (95% CI: 41.3-51.5) for self-assessment, and 0.7% for HIV and syphilis. Conclusions Syphilis infection is more serious in MSM population. Therefore, it is necessary to increase STD intervention in this population, increase the risk awareness of HIV / STD infection and promote its safe behavior.
