Iodine deficiency disorders in Neishabour

Iodine deficiency has been considered in Iran since 20 years ago and has been acknowledged recently. We studied iodine deficiency disorders in 1618 Neishabourian students. 60% of children had palpable and 2.5% had visible goiters. Height and weight of these children were lower than International and Tehranian children but higher than Isfahanian children. Hormone studies showed increased T4, decreased T3RU, increased T3 and T3/T4 ratio which are indicators of iodine deficiency
