上海市城区男性建筑工人的性行为特征及安全套使用情况调查

Study on features of sexual behaviors and condom use among male construction workers in the urban areas of Shanghai

目的了解上海市城区男性建筑工人的性行为特征、安全套使用情况及其影响因素,为大城市建筑工人的艾滋病性病防治策略提供依据。方法随机整群抽样选择上海两个城区12个工地的1 163名工人进行面对面问卷调查,内容包括人口学特征、工作和生活情况、艾滋病及安全套的知识和态度、性行为及安全套使用情况等。结果上海市城区男性建筑工人平均年龄(38.7±10.7)岁,小学及以下文化程度占22.0%,81.9%为已婚或同居;24.3%曾经有过多性伴,33.6%有过婚前性行为,10.5%有过婚外性行为,7.1%曾有商业性活动,而且73.7%很少或根本不使用安全套;年龄越大、每日工作时间越长的工人使用安全套的频率越低[比值比(Odds ratio,OR)分别为0.45和0.65]。安全套使用的促进因素为安全套能有效预防艾滋病的知识、性伴不愿使用安全套时能劝说其使用的技巧,以及知道从哪儿获得安全套,OR依次为1.96、3.94和3.33。结论男性建筑工人已成为大城市艾滋病/性病经性传播的重要桥梁人群,关注男性建筑工人并加大力度推广使用安全套已迫在眉睫。

Objective To describe features of sexual behaviors and condom use and the impact factors among the male construction workers in the urban areas of Shanghai, and to provide evidence for developing the strategy of human immunodeficiency virus（HIV）/sexual transmitted infection （STI） prevention and control in metropolitan cities. Methods Randomized cluster sampling was used to recruit 1 163 workers from two districts of Shanghai, who were interviewed by face to face questionnaires. The content of the questions included demographic characteris- tics, working and living conditions, acquired immunodeficiency syndromes （AIDS） related knowledge, attitude and behavior, and condom use. Results The mean age of the surveyed workers was （38.7±10.7） years. Of them 22.0% had primary schooling or less, 81.9 % were married or co-habitant, 24.3 ± used to have multi-sex partners, 33.6% had pre-marital sex activities, 10.5 % had extramarital activity, 7. 1% had commercial sex behavior, while the majority of male construction workers rarely or never used condom. Workers with older age and longer working time per day had the lower rate of condom use [odds ratio （OR） values were 0.45 and 0.65]. The knowledge of con- dom use against HIV/AIDS infection, the skill of persuading sex partners for condom use and knowing where to get condoms could promote condom use （OR values were 1.96, 3.94 and 3.33, respectively）. Conclusion The con- struction workers have become an important bridge population of HIV/STI via sexual transmission in large cities. Thus, it is urgent to pay close attention to male construction workers and promote condom use among them.
