铁缺乏与儿童智力的研究进展

Advances on the study of iron deficiency and mental development in children

目的儿童期是智力发育的关键时期。研究表明铁缺乏会影响儿童神经系统的发育,最终导致学习、记忆、认知功能的改变。近年来的文献主要集中在铁缺乏影响智力的机制、缺铁及铁干预对儿童智力的影响,如何预防儿童铁缺乏是最近研究的方向,提示预防儿童铁缺乏比铁干预更为重要。深入探讨铁缺乏与儿童智力发育的关系,对提高儿童智力水平及我国的全民素质有着重要的意义。

Childhood is a critical period for mental development.Iron deficiency will affect the development of nerve system and depress the learning ability,memory and cognitive function of children.There are a large number of literatures focusing on the mechanism of iron deficiency on mental retardation and the effect of iron reinforcement on iron deficient children in recent years.More attention has been paid to the prevention of iron deficiency.It has been proposed that the prevention of iron deficiency during early life of infants is more important than the reinforcement of iron in childhood.Exploring the relationship between iron deficiency and mental development is very important to improve the intelligence of children and the quality of whole population.
