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.
Study objectives were recruited through target sampling and anonymous questionnaires were adopted. Male sexual behaviors were compared between floating population and permanent registered residents.
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).
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.
探讨流动人口中男男性行为者（MSM）与艾滋病相关的性行为风险，并制定相关干预措施。
通过目标抽样招募研究对象，采用匿名问卷调查。比较流动人口与常住户籍居民的男性性行为情况。
在这些MSM中，流动人口在过去6个月内同性伴侣的平均数量、口交、肛交及与女性性行为的次数分别为9.61、8.61、7.52和1.17次。过去1个月内口交和肛交的性伴数量分别为2.89个和3.69个。这两个数字均高于常住户籍居民（P<0.05或P<0.01）。流动人口与男性发生肛交或与非婚女性性伴发生性行为时使用避孕套的比例分别为37.15%和23.28%。这些数字均高于常住户籍居民（P<0.05或P<0.01）。在流动人口中，与男性性工作者发生性行为、通过网络结识的男性发生性行为或与稳定女性性伴发生性行为的男性比例分别为17.89%、12.56%和31.86%。过去1年内男同性恋者中发生群交、与男性发生性行为时出血或与来自其他地区的男性发生性行为的比例分别为22.13%、31.38%和32.36%。这些数字均高于常住户籍居民（P<0.05或P<0.01）。
与性相关的高危行为在流动人口中比常住户籍居民更为普遍，因为他们更有可能将艾滋病病毒传播给其他地区的人。在开展健康干预措施时，应特别关注流动人口中的MSM。
