浙江省宁波市在婚与非在婚男男性接触者性行为特征及艾滋病感染状况比较

目的探讨婚姻状况对男男性接触者(MSM)人群艾滋病相关行为和感染的影响,为在该人群中开展有效的预防控制提供科学依据。方法采用滚雪球招募法,对宁波市744名非在婚MSM和455名在婚MSM进行问卷调查和血清学检测,比较两组间性行为特征及艾滋病、梅毒感染情况。结果在婚MSM艾滋病知识知晓率、同性性行为特征、艾滋病及梅毒感染率与非在婚组比较差异无统计学意义,但两组最近半年异性性行为特征差异有统计学意义,在婚MSM无保护性异性性行为发生率高于非在婚组。结论婚姻并不能制约MSM的同性高危性行为,而且更容易促使艾滋病病毒向普通女性蔓延。针对已婚MSM这一亚人群,有必要采用更有针对性的行为干预措施。

Comparison of HIV infection status and related high risk behaviors between married and unmarried men who have sex with men

Objective To explore the influence of marital status on HIV infection status and related high risk behaviors among men who have sex with men（ MSM） and provide scientific evidence for developing effective prevention and control strategy. Methods A total of 744 unmarried MSM and 455 married MSM were recruited by snowball sampling.Questionnaire survey was conducted and blood samples were taken to detect HIV and syphilis antibodies among them.Results There were no significant differences in AIDS related knowledge awareness,homosexual behavior and HIV infection status between married MSM and unmarried MSM. There was a significant difference in heterosexual behavior between two groups,and married MSM had more risk heterosexual behaviors than unmarried MSM. Conclusion In married MSM,marital status can not restrict their high risk homosexual behavior. Furthermore,they are more likely to spread HIV to women through heterosexual behavior. To control HIV transmission effectively,targeted behavior intervention is necessary for married MSM.
