云南省男性流动人群艾滋病高危行为现况分析

摘要:目的　了解云南省男性流动人群艾滋病高危行为现况，为制定干预策略提供依据。方法　采用社区概率抽样方法和整群抽样法对云南省保山市、红河州、昆明市3个州（市）男性流动人群进行横断面调查，通过一对一问卷调查，收集人口学及高危行为等相关信息，采用SPSS17.0进行统计学分析。结果　被调查对象共2405人，艾滋病总知晓率为95.8%，红河州流动人群知晓率低于保山及昆明（χ2＝101.846，47.75，均 P＜0.01）；最近1年与配偶发生性行为安全套使用率为3.8%；最近1年有5.0%的调查对象与临时性伴发生过性行为，安全套使用率为27.3%；最近1年4.4%的调查对象与暗娼发生过商业性行为，安全套使用率为36.2%。多因素Logistic回归显示，被调查对象与临时性伴及暗娼发生性行为时未坚持使用安全套的主要危险因素有:未婚、年龄大于35岁、本地居住12个月以上、属于建筑工人、对艾滋病知识不知晓。总吸毒率为0.2%（5/2405）。接受艾滋病咨询检测干预的比例为65.8%，接受同伴教育总干预比例为28.4%，最近1年做过艾滋病检测并知晓结果的比例为27.1%。结论　艾滋病知识知晓率较高，安全套使用率较低，干预力度及覆盖面有待提高。应重点加大建筑工人、单身、大年龄、外出时间较长及对艾滋病知识知晓较少的流动人群的干预力度。

Analysis of the current status of high-risk behaviors of AIDS among floating male populations in Yunnan Province

Abstract: Objective The study was conducted to assess the current status of high-risk behaviors for AIDS among floating male populations in Yunnan Province, so as to provide a reference for the development of intervention strategies against AIDS. Methods Floating male populations in Baoshan, Honghe, and Kunming Cities in Yunnan Province were selected by community probability sampling and cluster sampling and were cross-sectionally surveyed. Information relating to demography and high-risk behaviors of the subjects were collected by one-on-one questionnaire and were statistically analyzed by using SPSS17.0. Results A total of 2405 men were surveyed. The overall awareness rate was 95.8%, and floating populations in Honghe Prefecture had poorer awareness rate than those in Baoshan and Kunming (χ2=101.846, 47.75, P<0.01). In the past year, 3.8% of the subjects used condom during sexual intercourse with their spouses; 5% had sexual intercourse with temporary sexual partner and the condom usage rate was 27.3%; and 4.4% had commercial sexual intercourse with prostitutes and the condom usage rate was 36.2%. Multivariate logistic regression analysis showed that the major risk factors for the subjects to not insisting condom usage during sexual intercourses with temporary sex partners or prostitutes were unmarried, older than 35 years of age, having stayed in the City for more than 12 months, construction workers, and being unaware of knowledge of AIDS. The overall drug addiction rate was 0.2% (5/2405). The percentages of having received AIDS consultation, inspection, and intervention, total intervention with peer education, and having taken an AIDS examination in the past year and being aware of the results were 65.8%, 28.4%, and 27.1%, respectively. Conclusion While the rate of awareness on AIDS is high, the rate of condom usage is low. Enhancement in the intervention enforcement and coverage is required. The intervention should especially focus on construction workers, single men, middle aged adults, and floating populations with long migration history and with low awareness on AIDS.
