To assess the prevalence of Iodine deficiency disorders & deficiency status in selected population by estimation of urinary iodine excretion level.

Abstract

Iodine is vital micronutrient used by the body to make thyroid hormones. In body fluids, Iodine is found as iodide (I). In the thyroid gland, with the action of thyroid peroxidise, iodide is oxidised and get incorporated into tyrosine molecule of thyroglobulin (Tg) and form mono - and di-iodotyrosine. These are then coupled to produce Triiodothyronine (T3) and Thyroxin (T4) hormone for standard growth of human and mental development with an average requirement of 100-150 µg/day. Recommended intake of iodine as per UNICEF, ICCIDD and WHO, daily
