A high incidence of protein energy malnutrition (PEM) was found in a community survey of preschool children in rural northern Nigeria among whom gastro-enteritis is common. Wasting (less than 80% Weight/Height) was more common (37.9%) among those with scanty, unprotected water supplies than in those with copious protected water (10.2%) whereas the incidence of stunting (less than 90% Height/Age)) was similar. Severe coliform contaminatin of all water sources was demonstrable. Even higher numbers of coliforms in foods sampled suggests that other factors related to water supply may be more important than water purity in the genesis of the PEM/gastro-enteritis complex.
在尼日利亚北部农村学龄前儿童的社区调查中发现,蛋白质能量营养不良(PEM)的发生率很高,这些儿童中肠胃炎很常见。在水源匮乏且无保护措施的儿童中,消瘦(体重/身高低于80%)更为常见(37.9%),而在水源充足且有保护措施的儿童中则为10.2%,而发育迟缓(身高/年龄低于90%)的发生率相似。所有水源均检测出严重的大肠菌污染。所采集食物中大肠菌数量甚至更多,这表明在PEM/肠胃炎综合征的发生过程中,与供水相关的其他因素可能比水的纯净度更为重要。
