Alcohol drinking behavior and its relationship with AIDS related factors amoang MSM in Mianyang city

目的 了解男男性行为者（MSM）饮酒行为现状,分析饮酒行为与艾滋病相关因素的关系。方法 于2012年9月—2013年3月采用滚雪球采样法,对四川省绵阳城区符合条件的MSM进行招募和相关行为学、血清学匿名调查。结果 共调查402人,有饮酒行为占44.0（177人）。其中近6个月饮酒频率每月≤1次26.0%、2~3次30.5%,每周1~2次24.3%、3~4次5.1%、5~6次3.4%、≥1次/天10.7%。多因素分析结果：文化程度越低（OR=0.352,95%CI=0.166~0.747）、近1次男性肛交无保护性（OR=3.351,95%CI=1.131~9.925）、近6月异有性性行为（OR=2.800,95%CI=1.017~7.706）、近6月肛交人数≥3人（OR=2.339,95%CI=1.003~5.453）、吸烟（OR=0.372,95%CI=0.175~0.790）是饮酒行为高危因素。饮酒、吸烟与近6月无保护性男性肛交有交互作用（P=0.047）。结论 MSM饮酒较为普遍,饮酒行为与艾滋病高危行为相关,烟、酒有协同作用。在MSM艾滋病防治中应注重饮酒行为干预。

The results of multivariate analysis showed that the independent factors of alcohol drinking included education level （ odds ratio [ OR] = 0. 352,95% confidence interval E 95% CI] ：0. 166 -0. 747 ）, having unsafe anal sex in the latest homosexual activity （ OR = 3. 351,95% CI： 1. 131 - 9. 925 ）, having heterosexual activity during latest 6 months （ OR=2. 800,95% CI： 1. 017 -7. 706） ,having anal sex 3 times or more during the latest 6 months （OR = 2. 339,95% CI： 1. 003 -5.453 ）, and smoking （ OR = 0. 372,95 % CI：O. 175 - 0. 790 ） ; there were significant interactions among smoking, alcohol drinking, and unsafe homosexual anal sex （ P = 0. 047 ）.
