目的用同伴推动抽样(RDS)方法了解深圳地区男男性接触者(MSM)的AIDS相关知识和危险行为。方法2007年10-12月在深圳地区应用RDS方法招募MSM为研究对象,利用结构式问卷调查分析其H IV/AIDS知识、H IV风险感知、吸毒及性行为等。结果共招募351例MSM,平均年龄(27±6)岁,汉族占92.3%,未婚占78.1%,大专及以上文化程度占16.5%,非娱乐场所从业人员占61.5%。最近6个月,92.9%MSM和男性有肛交性行为,86.9%有口交性行为;68.5%有多个肛交性伴,每次使用安全套比例仅为57.0%;74.1%有多个口交性伴,每次使用安全套比例仅为13.1%;9.7%曾与男男性工作者发生性行为,其中24.2%不是每次使用安全套;28.5%MSM曾和女性(包括女性性工作者)发生性接触,其中仅36.8%每次使用安全套。13.7%MSM曾吸食过毒品。82.3%MSM艾滋病知识得分在7分以上(应得分为11分),但仅6.0%认为很可能感染HIV。结论深圳地区被调查的MSM的艾滋病风险感知认识程度低,且危险行为发生率较高。应加强MSM人群健康教育和行为干预,促进行为改变,降低艾滋病性病传播危险。
Objective To explore AIDS-related knowledge and risk behaviors of MSM in Shenzhen by using peer-driven sampling (RDS) method. Methods From October to December 2007, MSM was recruited as the research object by using RDS method in Shenzhen area. H IV / AIDS knowledge, H IV risk perception, drug abuse and sexual behavior were analyzed by using structured questionnaire. Results A total of 351 MSM patients were recruited, with an average age of (27 ± 6) years. Han Chinese accounted for 92.3%, unmarried 78.1%, college graduates 16.5% and non-entertainment occupations 61.5%. In the last 6 months, 92.9% of MSM and men have anal sex, 86.9% have oral sex and 68.5% have multiple anal sex with 57.0% of condom use. 74.1% have multiple oral sex partners, Only 13.1% of each use condoms; 9.7% had sex with MSM, 24.2% did not use condom each time; 28.5% of MSM had sexual contact with women (including female sex workers), of which only 36.8% Use condoms each time. 13.7% MSM had smoked drugs. 82.3% of MSM AIDS knowledge scores above 7 points (should be scored 11 points), but only 6.0% think it is likely to be HIV. Conclusion The HIV risk perception of MSM surveyed in Shenzhen is low-level and the risk behaviors are high. Health education and behavioral interventions should be strengthened for MSM populations to promote behavioral change and reduce the risk of AIDS transmission.
