Intelligence 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 endemic cretinism and goiter was tested with Standord-Binet method. Results indicated there existed a lot of mental retarded children in the iodine-deficiency areas, with most of them born before the implementation 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 been seen. It suggested that impairment to children's intelligence development caused by iodine deficiency during their fetal and infant periods was irreversible.
采用斯坦福-比奈智力量表对缺碘地区在胎儿期和婴儿期未补碘的儿童以及在地方性克汀病和甲状腺肿地区实现碘盐稳定供应三至四年后出生的儿童进行智力测试。结果表明，碘缺乏地区存在大量智力发育迟缓儿童，其中大多数在补碘措施实施前出生。为研究碘稳定供应可能引起的儿童智力发育变化，对生活在地方性克汀病地区的受试儿童进行了两年随访，未见儿童智力有改善。这表明胎儿期和婴儿期碘缺乏对儿童智力发育造成的损害是不可逆的。
