[Effects of iodine nutritional status of fetuses, infants and young children on their intelligence development in the areas with iodine-deficiency disorders].
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.
