[目的]了解女性性工作者艾滋病相关知识、行为状况,评价项目连续实施干预的动态效果。[方法]分层整群随机抽取山东省部分女性性工作者进行面对面问卷调查。2004年进行基线调查,之后进行干预,并于2005~2008年每年用相似问卷进行调查。[结果]2004~2008年分别调查1 218、7341、302、1 2091、218人,对艾滋病三大传播途径全部正确回答率分别为59.36%、68.94%、84.94%、84.45%、97.21%(P<0.01);对非传播途径的正确回答率分别为32.76%、37.47%、63.56%、85.03%、82.76%(P<0.01);最近1次商业性行为的安全套使用率分别为75.20%、71.66%、92.32%、85.94%、91.38%(P<0.01)。[结论]项目对女性性工作者的干预效果明显,但该人群艾滋病知识水平有待进一步提高。
[Objective] To understand the AIDS-related knowledge and behavior of female sex workers and evaluate the dynamic effects of continuous implementation of interventions. [Methods] Stratified cluster randomly selected some female sex workers in Shandong Province to conduct face-to-face questionnaire survey. The baseline survey was conducted in 2004 and then intervened. A similar questionnaire was used to investigate each year from 2005 to 2008. [Results] From 2004 to 2008, 1 218,7341,302,12091,218 people were investigated respectively. The correct answers to the three major transmission routes of AIDS were 59.36%, 68.94%, 84.94%, 84.45% and 97.21% respectively <0.01). The correct response rate to non-transmission was 32.76%, 37.47%, 63.56%, 85.03% and 82.76% respectively (P <0.01). The rates of condom use in the last commercial activity were 75.20% and 71.66 %, 92.32%, 85.94%, 91.38% (P <0.01). [Conclusion] The intervention effect of the project on female sex workers is obvious, but the knowledge level of AIDS in this population needs to be further improved.
