本研究以2001-02年出生的1,200名越南儿童为研究对象，利用纵向数据集研究了儿童营养不良对认知发展的影响。我们证明，如果研究人员忽略关于胎龄的数据，大多数儿童早期发育迟缓对认知的影响可以用显著的偏差来估计。早产时间对学龄前儿童认知成绩的负向影响具有统计学意义。然而，在控制了早产时身高的影响后，一岁时的身高对五岁时的认知成就的影响在统计学上并不显著。
A longitudinal dataset that follows 1,200 Vietnamese children born in 2001–02 is used to investigate the impact of child malnutrition on cognitive development. We demonstrate that the impact of early childhood stunting on cognition can be estimated with significant bias for a majority of children if researchers omit the data on gestational age. The negative impact of the length in preterm on the cognitive achievement of pre-schoolers is statistically significant. Having controlled for the effect of the length in preterm, however, the effect of height-for-age at age one on cognitive achievement at age five is not statistically significant.
