The relationship between physical growth and change in mental development on the Griffiths mental development scales was investigated in 127 stunted Jamaican children over a 2-year period. The role of nutritional supplementation in this relationship was examined. There were no consistent associations between changes in weight-for-height or head circumference and developmental change. Height gain over 2 years was significantly associated with change in mental age, and locomotor and hearing and speech subscale scores. Height gain in the first year predicted change in mental age, and hearing and speech in the second year. Some of the effect of supplementation on development was shared with linear growth. Therefore, nutrition probably explains part of the relationship between growth and development. However, supplementation also had effects on development independent of growth. The benefits of supplementation on development and the extent to which they were shared with growth varied among the subscales.
在两年时间里，对127名发育迟缓的牙买加儿童进行了研究，以探讨格里菲斯心理发展量表上身体生长与心理发展变化之间的关系。研究了营养补充在这种关系中的作用。身高体重比或头围的变化与发育变化之间没有一致的关联。两年内的身高增长与心理年龄变化、运动以及听力和言语子量表得分显著相关。第一年的身高增长预测了心理年龄的变化，第二年的身高增长预测了听力和言语的变化。补充营养对发育的一些影响与线性生长相同。因此，营养可能解释了生长与发育之间关系的一部分。然而，补充营养对发育也有独立于生长的影响。补充营养对发育的益处以及与生长共享的程度在各子量表中有所不同。
