为了摸索在重点人群中开展干预活动控制艾滋病传播的经验 ,我们于 1997年开始在内蒙伊盟长途卡车司机人群中开展了以宣传教育为主要内容的干预活动。具体结果如下 :经过一年的干预 ,干预人群知识平均正确率提高 54 55%。三种传播途径的知晓率均在 90 %以上 ,非传播途径的知晓率也均有了大幅度的提高。提示此种干预方法在预防知识知晓率较低的目标人群中能获得较好的效果 In order to explore the experience of conducting interventions in key populations to control the spread of AIDS, we started the campaign of advocacy and education as an important component of the long-distance truck driver group in Inner Mongolia in 1997. Specific results are as follows: After a year of intervention, the average correct rate of intervention population increased 54 55%. The awareness of the three routes of transmission were all above 90%, and the awareness rate of non-transmission routes also increased significantly. Suggesting that such interventions can achieve better results in the target population with a lower awareness rate of knowledge
