摘要
目的比较2015年和2019年北京MSM人群调查样本感染艾滋病危险行为特征。方法2015年和2019年每年5—8月采用国家艾滋病哨点监测问卷对男男性行为(men who have sex with men,MSM)人群进行横断面调查,采集调查对象血液标本进行人类免疫缺陷病毒(human immunodeficiency virus,HIV)、梅毒和丙型肝炎病毒(hepatitis C virus,HCV)抗体检测。结果与2015年相比,2019年调查对象年龄偏大、结婚的比例高、文化程度低、最近6个月与同性发生性行为比例下降、最近6个月与异性发生性行为比例上升;2015年和2019年最近6个月与同性肛交使用安全套的频率约为60%。结论北京MSM人群感染艾滋病危险行为持续存在,应结合年龄大、文化程度低、结婚率高的特点采取针对性干预措施,降低MSM感染艾滋病高危行为,继续加强监测,及时获得该人群危险行为指标动态变化趋势,指导干预策略的制定。
Objective To compare the characteristics of HIV infection related risk behaviors among the subjects from MSM population surveys in Beijing in 2015 and 2019.Methods The cross-sectional surveys of the MSM population from May to August were conducted using the National HIV Sentinel Monitoring Questionnaire in 2015 and 2019.The blood samples of the respondents were collected to test for HIV,syphilis and hepatitis C virus(HCV)antibodies.Results Comparing to 2015,the subjects in 2019 were older in age with higher proportion of marriage and lower level of education,while the ratio of having sex with men in the past 6 months decreased and the ratio of having sex with females in the past 6 months increased.The rate of condom usage during anal sex with male in the past 6 months was about 60%in 2015 and 2019.Conclusions The risk sexual behaviors of MSM population in Beijing persisted.Intervention measures in focus on the old age,low education,and high marriage rate should be implemented to reduce effectively high risk sexual behaviors in MSM.Continuous surveillance should be enhanced to obtain timely changes of risk behavior indicators in this population to guide the formulation of intervention strategies.
