内蒙古男男性接触者HIV感染相关影响因素调查

目的了解内蒙古男男性接触人群(men who have sex with men,MSM)的艾滋病感染状况,分析影响MSM人群艾滋病感染的相关因素,为防治工作提供理论依据。方法调查对象选取在最近六个月与男性发生过口交或肛交性行为及同伴认定为同性恋的男性,且自愿参加问卷调查和艾滋病检测者,采用logistic回归方法分析人口学特征、艾滋病相关知识、行为学、血清学等因素对HIV感染状况的影响。结果本次共调查802名男男性接触者,其中现住址在内蒙古的占86.66%,其他省市的占13.34%;18~39岁占74.44%;高中及以上的占72.19%;商业性服务的占5.87%,双性恋的占31.30%。MSM人群的艾滋病防治知识知晓率达到88.53%以上。logistic回归分析显示,文化程度、梅毒感染情况为危险因素,安全套的使用频率情况为保护因素。结论文化程度、安全套的使用频率及梅毒感染情况是MSM人群艾滋病感染的相关因素,需要通过多途径、多部门合作进行干预,遏制HIV在人群中的传播。

Factors influencing HIV infection among MSM in Inner Mongolia

Objective To investigate the status of AIDS infection among MSM in Inner Mongolia, to analyze the related factors influencing AIDS infection, and to provide a theoretical basis for its prevention and control. Methods We selected males who had oral sex or anal sex with another male in recent 6 months and homosexual males identified by peerswho’d likevoluntarily participate in questionnaire survey and AIDS detection to serve as the surveyed subjects. Logistic regression analysis was performed to examine the factors (including demographic characters, AIDS-related knowledge, behavior and serology) impacting the status of AIDS infection. Results A total of 802 MSM were interviewed in this survey. 86.66% of the MSM lived in Inner Mongolia, and 13.34% came from other provinces and cities. MSM aged 18-39 years, MSM with educational background of senior high school or above, MSM with commercial sex services and MSM with bisexual behavior accounted for 74.44%, 72.19%, 5.87% and 31.30% respectively. The awareness rate of AIDS prevention and treatment knowledge in the MSM was more than 88.53%. Logistic regression analysis showed that educational background and syphilis infection were the risk factors, while the frequency of condom use was the protective factor. Conclusions Educational background, frequency of condom use and syphilis infection are the factors associated with HIV infection among MSM. It is necessary to perform interventions through multi-channel and multi-sector cooperation so as to control the spread of HIV in the population.
