亚文化特征对男男性接触者高危性行为的影响

THE IMPACTS OF SUBCULTURE CHARACTER ON THE HIGH-RISK SEXUAL BEHAVIORS AMONG MEN WHO HAVE SEXUAL BEHAVIOR WITH MEN

目的:了解男男性接触者(Men who have sex with men,MSM)亚文化特征及高危性行为状况,为开展HIV/STIs预防干预活动提供依据。方法:对进入同性恋酒吧中活动的MSM进行问卷调查,调查内容包括社会人口特征,高危性行为状况和性伴特征等。结果:MSM中多性伴现象普遍,安全套使用率较低;在最近6个月中,与同性发生高危性行为的报告率为69.5%,与异性发生高危性行为的报告率为43.7%,有30.5%的人报告既有同性又有异性高危性行为。经多因素分析表明,年龄大是同性高危性行为的影响因素,既有同性又有异性高危性行为的影响因素为年龄大和最近2个月中有过4个及以上同性肛交性伴,女性高危性行为的影响因素为年龄大、非同性性取向、一生中拥有4个及以上异性性伴和在最近2个月中有2个及以上同性偶然性伴。结论:促使HIV/STIs在MSM人群中传播的危险因素广泛存在,为了达到有效的行为干预效果,在进行干预时,要充分考虑他们的亚文化特征。

Objective： To find out the subculture character and high-risk sexual behavior among men who have sexual behavior with men in gay bars and to provide basis for HIV/STIs prevention and control. Methods： A cross - sectional survey was conducted in gay bars included the demographic characteristics, sexual behavior, sexual partners and so on. Results： Multiple sex partners were common, few people could insistently use condom during sexual behaviors. The self- reported unprotected sexual behavior with men was 69.5%, and that for high rish behavior with women was 43.7%, and that for high risk behavior with both men and women was 30.5 % in the past 6 months. Logistic regression analysis showed that subculture character for high risk behavior with men was older, and that for high risk with both women and men were older and having multiple sexual partners. And subculture character included older and non- gay men as well as having multiple sexual partners were the predictor of the high risk behavior with women. Conclusion： The driving factors of HIV/STIs transmission were broadly existed among MSM. In order to obtain an efficient effect, the subculture character of MSM should be taken into account during HIV/STIs prevention.
