This report describes the results of a community-based Aedes aegypti control program in Merida, Yucatan, Mexico. Baseline surveys concerning knowledge, beliefs, and practices of 577 women and a larval survey of 616 house lots were carried out in October 1989. Following development of a public health communication intervention from this data, the program was implemented in six communities. Evaluation used an untreated control group design with pretest and two post-tests, one at completion and one six months later. Significant changes in knowledge and behavior were seen in the treatment group in both post-tests. Women in the intervention group were able to identify the Ae. aegypti mosquito, the larval production sites of the mosquito, and appropriate control methods. A behavior change proxy was measured by examining changes in the Breteau (number of positive containers/100 houses surveyed) and container indices. The Breteau index remained the same in the intervention group while it increased significantly in the comparison group. Changes were also seen with respect to individual containers. This project demonstrated that a community-based communication program aimed at larval production site elimination or control can be effective in changing behavior and reducing larval production sites.
本报告描述了墨西哥尤卡坦州梅里达市一项基于社区的埃及伊蚊控制项目的结果。1989年10月，对577名女性进行了关于知识、信念和行为的基线调查，并对616处房屋地段进行了幼虫调查。根据这些数据制定了公共卫生传播干预措施后，该项目在六个社区实施。评估采用了未处理的对照组设计，进行了预测试和两次后测试，一次在项目完成时，一次在六个月后。在两次后测试中，治疗组的知识和行为都出现了显著变化。干预组的女性能够识别埃及伊蚊、该蚊虫的幼虫滋生地以及适当的控制方法。通过检查布雷托指数（阳性容器数量/调查的100所房屋）和容器指数的变化来衡量行为改变指标。干预组的布雷托指数保持不变，而对照组则显著上升。在单个容器方面也出现了变化。该项目表明，一项旨在消除或控制幼虫滋生地的基于社区的传播项目能够有效改变行为并减少幼虫滋生地。
