摘要
使用Ｓｔａｎｔｏｒｄ－Ｂｉｒｅｄ量表，对地方性克汀病及地方性甲状腺肿病区补碘前处于胚胎至婴幼期的儿童和碘盐稳定供应３～４年后出生的儿童进行智力测验，结果表明碘缺乏地区确实存在众多的智力低下儿童，主要集中在补碘前出生的儿童。为观察稳定供碘后儿童智力发育的变化情况，我们对地方性克汀病区的受试儿童追踪观察了两年。结果表明未能进一步改善儿童的智力水平，说明胚胎至婴幼期缺碘对儿童智力发育的损害是不可逆性的。
ntelligence in children without iodine supplement during their fetal and infant periods,and in those born three to four years after the implementation of stable supply of iodized salt in the areas with endem-ic cretinism and goiter was tested with Standord-Bired method.Results indicated there existed a lot of mental retarded children in the iodine-deficiency areas,with most of them born before the implementa-tion of iodine supplement.In order to study the changes of intelligence development in children probably induced by stable supply with iodine,the tested children living in the areas with endemic cretinism were followed-up for two years,and no improvement in children's intelligence could be seen. It suggested that impairment to children' s intelligence development caused by iodine deficiency during their fetal and infant periods was irreversible.
