The impact of a water, sanitation and hygiene education intervention project on diarrhoeal morbidity in children under 5 years old was evaluated in a rural area of Bangladesh. Data were collected throughout 1984-1987, covering both pre- and post-intervention periods, from an intervention and a control area. The 2 areas were similar with respect to most socio-economic characteristics and baseline levels of diarrhoeal morbidity. The project showed a striking impact on the incidence of all cases of diarrhoea, including dysentery and persistent diarrhoea. By the end of the study period, children in the intervention area were experiencing 25% fewer episodes of diarrhoea than those in the control area. This impact was evident throughout the year, but particularly in the monsoon season, and in all age groups except those less than 6 months old. Within the intervention area, children from households living closer to handpumps or where better sanitation habits were practised experienced lower rates of diarrhoea. These results suggest that an integrated approach to environmental interventions can have a significant impact on diarrhoeal morbidity.
在孟加拉国的一个农村地区，评估了一项水、环境卫生与个人卫生教育干预项目对5岁以下儿童腹泻发病率的影响。在1984年至1987年期间，从一个干预地区和一个对照地区收集了涵盖干预前后时期的数据。这两个地区在大多数社会经济特征和腹泻发病率基线水平方面相似。该项目对包括痢疾和持续性腹泻在内的所有腹泻病例的发病率产生了显著影响。到研究期结束时，干预地区的儿童腹泻发作次数比对照地区的儿童少25%。这种影响全年都很明显，尤其是在季风季节，并且在除6个月以下婴儿以外的所有年龄组中都很明显。在干预地区内，居住在离手压泵较近或卫生习惯较好的家庭中的儿童腹泻发生率较低。这些结果表明，综合环境干预方法可对腹泻发病率产生重大影响。
