[目的]了解男男性接触者(MSM)关于艾滋病的知识、态度、行为、信念等情况,为确定有效的干预措施和预防控制对策提供依据。[方法]对22名感染艾滋病的MSM按调查时间序列进行1︰3比例的配对,采用Cox回归模型进行病例对照分析。[结果]单因素回归分析显示,病例组与对照组间梅毒感染情况、1年内有性病症状、半年内有高危行为、近半年有同性肛交偶然性伴等4个因素存在显著差异;进一步采用多因素回归分析,1年内有性病相关症状可能是艾滋病感染的危险因素。[结论]在MSM人群中开展宣传干预工作,应着重提高该人群HIV/STDs感染危险性意识,减少性伴数,提高安全套使用率。
[Objective] To understand the knowledge, attitudes, behaviors and beliefs of MSM about AIDS and provide the basis for determining effective interventions and prevention and control measures. [Methods] Twenty-two HIV-infected MSMs were matched in a 1: 3 ratio according to the time series of investigation. Cox regression models were used for case-control analysis. [Results] Univariate regression analysis showed that there were significant differences among the four groups in terms of syphilis infection, the incidence of sexually transmitted disease within one year, high-risk behavior within six months, and occasional sexual partners of the same sex in the past six months. Further multi-factor Regression analysis, within 1 year of STD-related symptoms may be a risk factor for HIV infection. [Conclusion] To carry out the propaganda and intervention work in MSM population, we should focus on raising awareness of the risk of HIV / STDs infection in this population, reducing the number of sexual partners and increasing the rate of condom use.
