of urinary iodine (UI), which is a valid index for iodine intake, since 90% of iodine excretion from the body occurs through urine and only a small amount is lost through the skin and intestines [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Usually

Introduction Adequate dietary iodine consumption, as determined by the urinary iodine concentration (UIC), is necessary for a normal thyroid function. During pregnancy, iodine requirements are increased [ 1 ] as a result of both the normal
