摘要
目的通过对不同性取向的男男性接触者(MSM)行为特征进行分析,探索该人群在艾滋病病毒(HIV)传播中的桥梁作用。方法采用符合设计要求的问卷表,对选取的符合要求的MSM进行面对面的问卷调查。结果调查对象的性取向以同性恋者(Gay)和双性恋者(Bi)为主,分别为78.9%和16.7%。其中Gay和Bi过去6个月与女性发生性行为的比例分别为14.1%和66.0%;从未使用安全套比例分别为82.4%和70.1%。过去6个月与男性发生肛交行为中,Gay的接受性肛交行为高于Bi(χ2=18.46,P<0.001),插入性肛交行为低于Bi(χ2=18.38,P<0.001)。安全套坚持使用率为25%~40%,安全套的使用率差别无显著性。16.4%的Gay和21.3%的Bi有商业性行为。59.7%的MSM通过网络寻找性伴,1.7%的MSM有吸毒行为,13.1%的MSM检测过HIV。结论Gay和Bi中拥有很高比例的女性性伴,同时存在传播HIV的高危行为,他们可能在HIV从高危人群向一般人群传播中起桥梁作用。
Objective To study behavioral :Features of men who have sex with men (MSM) with different sexual orientations and explore their bridging role in HIV transmission. Methods A face to face questionnaire investigation was conducted among MSM from June to July, 2006. Results The proportions of Gay and Bi among MSM were 78.9 % and 16.7 %, respectively;the respective proportions of having sex with females among Gay and Bi were 14.1% and 66.0 % in the past 6 months, and the proportions of never using condom were 82.4 % and 70.1%, respectively. The rate of receptive anal intercourse was higher among Gay (X^2 = 18.46, P 〈 0.001 ), while the rate of inserting anal intercourse was higher among Bi (X^2 = 18.38,P 〈 0.001). But the rate of consistent condom use was from 25% to 40% ;16.4% of Gay and 21.3% of Bi had commercial sexual behaviors;59.7% of MSM looked for sexual partners through internet, 1.7% of MSM reported having experience of drug use and 13.1% of them reported having received HIV antibody test. Conclusion The proportions of having female partners are very high among Gay and Bi, and high risk behaviors are common among them. As a consequence, MSM including both Gay and Bi may serve as a bridge to transmit HIV from the high risk population to the general populations.
