男男性行为者中流动人口艾滋病高危行为研究

目的 探讨男男性行为者(MSM)中流动人口艾滋病高危行为状况.方法 采用定向抽样法开展横断而调查,对9个城市2250名MSM的匿名调查问卷进行分析,比较其中流动人口与常住人口两亚人群的高危行为发生状况.结果 MSM流动人口组近6个月性伴数(平均9.61个)、口交(平均8.61个)和肛交(平均7.52个)性伴数,近1个月口交(平均2.89个)和肛交(平均3.69个)性伴数,近6个月女性性伴数(平均1.17个)均明显高于常住人口组(P<0.05或P<0.01).MSM中近6个月内流动人口组与男性肛交时以及同非妻子女性性交时每次使用安全套的百分率(分别为37.15%、23.28%)均低于常住人口组(P<0.05或P<0.01).MSM流动人口组从事男性性工作、与gay网友性交过、近1年在男性间参加群交、近1年与男性性交时出血、近1年在外地与男性性交、目前有固定女性性伴(分别为17.89%、12.56%、22.13%、31.38%、32.36%、31.86%)均明显高于常住人口组(P<0.05或P<0.01).结论 MSM流动人口具有比常住人口更多的HIV高危行为;该亚人群具有将HIV传播到其他地区的条件,应加强对MSM流动人口的行为干预,以阻断其在HIV传播过程中的"桥梁"作用.

Study on the high risk behaviors related to AIDS among men who having sex with mell in the floating population

Objective To explore the risks on sexual behaviors related to AIDS among men who having sex with men (MSM) in floating population and to develop relevant interventions. Methods Study objectives were recruited through target sampling and anonymous questionnaires were adopted. Male sexual behaviors were compared between floating population and permanent registered residents.Results Among those MSM, the average numbers of same-gender partners, oral sex, anal sex and sex with females during the past 6 months among floating population were 9.61, 8.61, 7.52 and 1.17 respectively. Numbers of partners on oral sex and anal sex during the past month were 2.89 and 3.69 respectively. Both figures were higher than those of the permanent registered residents (P<0.05 or P< 0.01). The rates of condom use among floating population when having anal sex with men or with non-marital female partners were 37.15% and 23.28% respectively. The figures were all higher than those of permanent registered residents' (P<0.05 or P<0.01). Among floating population, the percentages of men who had sex with male sex workers or who had sex with men acquainted through inter-net or with stable female sex partners were 17.89%, 12.56%, and 31.86% respectively. The rates of men who had group sex among gay men, who bled when having sex with men or who had sex with men from other areas during the past year were 22.13%, 31.38% and 32.36% respectively. The figures were all higher than those of permanent registered residents' (P<0.05 or P<0.01). Conclusion Sex-related high risk behaviors were more ubiquitous among floating population than those of permanent registered residents because they were more likely to transmit HIV to people from/to other areas. More attention should be paid to the floating population with MSM in particular, when health interventions are carried out.
