Iodine is essential for thyroid hormone production and critical for brain development. In pregnancy, inadequate or excessive iodine intake can lead to impaired cognitive function in children, but the level of intake at which impairment occurs is unclear. Recently, pregnant women have increased their iodine intake due to the mandatory iodine fortification and the recommendation for iodine supplementation during pregnancy. We will examine associations between maternal iodine intake, thyroid function in pregnancy and cognitive function of children; and determine iodine levels during pregnancy associated with optimal cognitive function. This work will inform public health policy on iodine supplementation in pregnancy.
