The influence of pre-existing malnutrition on the severity of diarrhoea was investigated by assessing attack-rate and duration of diarrhoea in children aged between 6 months and 32 months at the beginning of the rainy season in Malumfashi village area, northern Nigeria. There were 1.4 attacks of diarrhoea per child during the 3 month rainy season and children spent 10.5% of the time with diarrhoea. The frequency of diarrhoea was not increased in underweight (less than 75% weight/age) or stunted (less than 90% height/age) children, but those who were wasted (less than 80% weight/height) experienced 47% more episodes of diarrhoea than those who were not wasted. However, pre-existing malnutrition affected the duration of diarrhoea, which was 33% longer in underweight children, 37% longer in stunted children, and 79% longer in wasted children.
通过评估尼日利亚北部马卢姆法希村地区雨季开始时6个月至32个月大儿童的腹泻发病率和腹泻持续时间，研究了既往营养不良对腹泻严重程度的影响。在为期3个月的雨季中，每名儿童腹泻发作1.4次，儿童腹泻时间占总时间的10.5%。体重不足（低于体重/年龄的75%）或发育迟缓（低于身高/年龄的90%）的儿童腹泻频率并未增加，但消瘦（低于体重/身高的80%）的儿童腹泻发作次数比未消瘦的儿童多47%。然而，既往营养不良影响腹泻持续时间，体重不足的儿童腹泻持续时间长33%，发育迟缓的儿童长37%，消瘦的儿童长79%。
