EVALUATION OF A WATER-SANITATION INTERVENTION IN EGYPT

该实地项目的目的是评估 水卫生联合干预对儿童肺炎发生的影响 居住在中国的一项研究人群中的腹泻和其他靶向结果 上埃及的阿苏特省。 20个村庄，总人口约为 10,000人被随机分配接受干预 (n=10)或不干预(n=10)。干预措施包括 提供印度马克二期管井和家用厕所 以及强调个人卫生和水的教育方案 行为。为了评估干预的影响，所有家庭 在一段时间内，对这些村庄进行了纵向监视 一年的随访期。 感兴趣的结果包括观察到的水卫生行为， 环境清洁度、水微生物质量，以及 主要结果，3岁以下儿童腹泻的发生率 年龄。该干预是在1990年底实施的，并进行了后续 一直持续到1991年。来自该项目的数据现已输入 目前正在进行最后的数据编辑工作。 初步分析表明，干预在#年是成功的。 将儿童腹泻的发病率降低17%，这一效果 包括水样和非水样腹泻，以及急性和非水样腹泻 持续性腹泻。对试验的分析将在93财年继续进行。

The purpose of this field project is to evaluate the impact of a combinant water-sanitation intervention on the occurrence of pediatric diarrhea and other targeted outcomes in a study population residing in the Assiut governorate of Upper Egypt. 20 villages, which together included a population of approximately 10,000 persons, were randomly assigned to receive the intervention (N=10) or no intervention (N=10). The intervention consisted of provision of India Mark II tubewells and household latrines, together with an educational package stressing personal hygiene and water behaviors. To assess the impact of the intervention, all families in these villages were followed with longitudinal surveillance during a one-year follow-up period. Outcomes of interest included observed water-sanitation behaviors, environmental cleanliness, water microbiological quality, and, as the primary outcome, the occurrence of diarrhea in children under 3 years of age. The intervention was implemented during late 1990, and follow-up continued through 1991. Data from the project have now been entered into computerized media, and final data editing is now in progress. Preliminary analyses indicate that the intervention was successful in reducing the rate of pediatric diarrhea by 17%, and that this effect included both watery and non-watery diarrheas, as well as both acute and persistent diarrheas. Analyses of the trial will continue in FY 93.
