This study examined the role of food and water contamination in a health impact evaluation of a water and sanitation intervention project. Although lower diarrhoea rates were found in the improved area no consistent difference in food and water contamination was observed between areas. Furthermore, no relationship was found between contamination and diarrhoea in either area, even after controlling for the nutritional status of children. These results imply that other vehicles of transmission might be more important than food and water in diarrhoeal transmission. The focus of interventions should therefore be on changing behaviours to improve overall hygiene.
本研究在一项水与环境卫生干预项目的健康影响评估中，考察了食物和水污染的作用。尽管在改善区域发现腹泻率较低，但各区域之间在食物和水污染方面未观察到一致的差异。此外，即使在控制了儿童营养状况之后，两个区域中均未发现污染与腹泻之间存在关联。这些结果表明，在腹泻传播中，其他传播媒介可能比食物和水更为重要。因此，干预措施的重点应放在改变行为以改善整体卫生状况上。
