Iodine is one of the main elements for human development; it intervenes in the synthesisof thyroid hormones and neurodevelopment. Iodine deficiency affects to one thirdof world population. Iodine deficiency is responsible of disorders as goitre and infant cretinism,and it raises child mortality. Mild iodine deficiency can also be responsible ofmild neurologic developmental disorders as borderline cognitive skills or attention deficitand hyperactivity disorders. In Spain there are communities with mild iodine deficiency.One of the methods to evaluate the community iodine deficit is to know de ratio of theneonatal TSH > 5 MU/l from neonatal mass screening. During pregnancy yoduria oftendecreases under level of deficiency (defined by OMS). Nowadays there aren’t proofs ofefficacy of iodine supplementation since the beginning of pregnancy in the long termneurodevelopment of the child. Authors recommend iodized salt use for all the populationand to know the value of TSH neonatal screening of each child. It is necessary tostudy the effects of iodine supplementation during pregnancy in the long term neurodevelopmentof the children (AU)
