目的了解男男性行为人群(MSM)安全套携带现状及影响因素。方法 2012年9月至2013年3月,在四川省绵阳市,采用滚雪球抽样法招募调查对象,使用自行设计的调查表进行匿名询问式行为学调查,采集血样进行血清学检测。结果 397例MSM中,安全套携带率35.5%(141例);携带安全套者近6个月肛交有保护性占69.5%(91/131),无保护性占30.5%(40/131)(χ2=12.020,P=0.001)。多因素分析显示,月收入>2000元[比值比(OR)=2.233,95%可信区间(CI):1.252~3.984]、性角色1号(OR=2.765,95%CI:1.199~6.376)、有风险意识(OR=3.879,95%CI:1.101~13.667)、近1年接受过同伴教育(OR=2.907,95%CI:1.621~5.508)、近6个月肛交有保护性(OR=2.748,95%CI:1.505~5.017)、近6个月肛交人数>1(OR=2.277,95%CI:1.264~4.100)等,是MSM安全套携带的促进因素。结论 MSM安全套携带率总体水平较低,存在携带与使用分离。在艾滋病防治中应注重安全套携带和使用的同步促进。
Objective To understand the current situation and influencing factors of the carrying of condoms in men who have sex with men (MSM). METHODS: From September 2012 to March 2013, Mianyang City, Sichuan Province, the snowball sampling method was used to recruit respondents. Anonymous inquiry behavioral investigation was conducted using a self-designed questionnaire. Blood samples were collected for serological testing. Results Among the 397 MSM cases, the carrying rate of condom was 35.5% (141 cases). In the nearly 6 months of carrying condoms, 69.5% (91/131) had anal protection and 30.5% (40/131) had no protection (χ2 = 12.020, P = 0.001). Multivariate analysis showed that monthly income> 2,000 yuan [odds ratio (OR) = 2.233, 95% confidence interval (CI): 1.252 to 3.984], sexual role 1 (OR = 2.765, 95% CI: 1.199 to 6.376) (OR = 3.879, 95% CI: 1.101 ~ 13.667), companion education in the past year (OR = 2.907, 95% CI: 1.621-5.508) and protective anal sex in the past 6 months 2.748, 95% CI: 1.505 ~ 5.017). The number of anal intercourse> 1 (OR = 2.277,95% CI: 1.264 ~ 4.100) in the past 6 months was the promoting factor of MSM condom carrying. Conclusion The overall MSM condom carrying rate is low, there is separation between carrying and using. In the AIDS prevention and control should focus on the synchronization of condom carrying and use.
