目的 探讨艾滋病相关知识结构对男男性行为者(MSM)安全套使用率的影响.方法采用滚雪球和广告招募的方式,以自行设计的调查问卷对长沙市270名MSM进行面对面访谈,采用SPSS 13.0软件进行数据录入和分析.结果 84.1%(212/252)的MSM自述最近3个月与同性有过肛交或口交行为,每次肛交均使用安全套的占42.5%(90/212),每次口交均使用安全套的仅占16.0%(34/212).99.2%(250/252)的调查对象都听说过艾滋病,但是只有73.0%(184/252)知道HIV是"人类免疫缺陷病毒"的缩写;48.4%(122/252)的人知道HIV和艾滋病不是同一回事;73.4%(185/252)的调查对象清楚知晓艾滋病的三大传播途径;82.5%(208/252)的人认为正确使用安全套可以有效预防艾滋病.63.5%(160/252)的调查对象知晓HIV感染者经过治疗可以像其他慢性病患者一样生活;34.9%(88/252)的调查对象认为感染了HIV就意味着死亡;22.6%(57/252)的人认为感染了HIV生活就失去了意义;57.1 %(144/252)的人认为感染了HIV会丧失很多权利.12.7%(32/252)的人有与HIV感染者相处的经历.多因素Logistic回归分析显示,HIV感染者相处史[OR=2.982,95%CI(1.246,7.140)]、认为感染了HIV就意味着死亡[OR=1.550,95%CI(1.103,2.180)]是艾滋病高危性行为的保护因素;而认为HIV感染者可以像其他慢性病患者一样生活[OR=0.677,95%CI(0.488,0.939)]是高危性行为的危险因素.结论 MSM人群艾滋病相关知识结构在一定程度上影响安全套的使用率,应加强对该人群的宣传教育内容,改变宣教策略,以降低危险性行为的发生率.%Objective To explore the impact of AIDS - related knowledge on condom use rate among men who have sex with men ( MSM ) . Methods Through snowball sampling and advertisement, 270 MSM were recruited to fill out a self -made questionnaire through face - to - face interviews. SPSS 13.0 was used for data analysis. Results A total of 252 (93. 3% ) valid questionnaires were collected. Totally 84. 1% ( 212/252 ) subjects reported anal or oral sex with men within the past 3 months. Among them, 42. 5% ( 90/212 ) used condom each time they had anal sex, and the percentage is 16. 0% ( 34/212 ) for oral sex. Almost all ( 99. 2% , 250/252 ) participants had heard about AIDS, but only 73. 0% ( 184/252 ) knew what HIV stands for. About 48. 4% ( 122/252 ) knew HIV and AIDS were not the same thing; 73. 4% ( 185/252 ) clearly knew the three major transmission routs of HIV; 82. 5% ( 208/252 ) knew that correct condom use could prevent HIV infection; 63. 5% ( 160/ 252 ) knew that HIV infected patients after treatment can live as other chronic disease patients; 34. 9% ( 88/252 ) participants considered that HIV meant deaths; 22. 6% ( 57/252 ) thought life meaningless if got infected with HIV; 57. 1% ( 144/252 ) believed that they would be deprived of many rights if got infected with HIV; 12. 7% ( 32/252 ) had experience of contact with HIV infected people. Multivariate logistic regression analysis showed that HIV contact experience [ OR =2.982, 95% CI ( 1.246, 7. 140 ) ], thinking that HIV meant deaths [ OR = 1. 550, 95% CI ( 1. 103 , 2. 180 ) ] were protective factors for condom use; while considering HIV infection as a chronic illness [ OR =0. 677 , 95% CI ( 0. 488, 0. 939 ) ] was a risk factor for condom use. Conclusion The AIDS - related knowledge impacts the condom use rate among MSM. Health education on AIDS and HIV should be promoted through improved approaches to increase condom use among MSM.
