Severe malnutrition during the fetal or infancy period in animals and humans decreases brain size, reduces the number of brain cells, and results in behavioral abnormalities. The relationship between lesser degrees of malnutrition and intellectual development is more complex. Social, genetic, and other factors assume greater roles under the latter conditions. Before we can draw firm conclusions that malnutrition per se is the cause of mental subnormality, we must complete analyses from on-going longitudinal studies in order to clarify the role of parental interaction with malnourished child and of the social environmental factors which accompany malnutrition.
动物和人类在胎儿期或婴儿期遭受严重营养不良会导致脑容量减小、脑细胞数量减少，并引发行为异常。程度较轻的营养不良与智力发育之间的关系更为复杂。在这些情况下，社会、遗传和其他因素起着更大的作用。在我们能够得出营养不良本身就是智力低下原因的确切结论之前，我们必须完成正在进行的纵向研究分析，以阐明父母与营养不良儿童互动的作用以及伴随营养不良的社会环境因素的作用。
