Background & Aims: Despite adequacy of dietary iodine intake in the Islamic Republic of Iran, the prevalence of goiter is still high in certain parts of the country such as West Azarbaijan province.  This investigation was undertaken to evaluate urinary iodine excretion (UIE) and prevalence of goiter among (10-17 years-old) schoolchildren in Urmia County. Materials & Methods: Schoolchildren (n...

ازدیاد درازمدت سطح سرمی هورمون تیروئید ممکن است بر توده معدنی استخوان (bmd) بویژه در زنان یائسه اثر داشته باشد. این اثر در مواردی که هورمونهای تیروئید به طور کوتاه مدت افزایش دارند، بررسی نشده است. به منظور تعیین bmd در بیمارانی که به مدت طولانی لووتیروکسین مصرف کرده و آنها که یک تزریق محلول ید روغنی داشته اند، 68 بیمار دچار گواتر ساده، با میانگین سنی 6±51 سال که فاقد عوامل مداخله گر دیگر بودند...

This study was performed to evaluate the implementation of the National IDD Council program in 2001 among 7-10-year-old children in Semnan pr...

Introduction: Biosynthesis of thyroid hormone and consequently the requirement for iodine have been established to increase during gestation mainly due to increased iodine demand by the fetus. Therefore, diminished iodine intake by the mother during early pregnancy eventually leads to the development of iodine deficiency disorders(IDDS)  in the offspring. The present study aimed to explore...

Background & Aims: This study was aimed to assess the interrelationship between urinary iodine excretion (UIE) and thyroid stimulating hormones (TSH) levels in pregnant women during the first trimester. Materials & Methods: Women (n=485 age: >14 years old without any history of thyroid dysfunction) were recruited at their first prenatal consult before 12 weeks of amenorrhea. Proportion of p...

The aim of the present investigation was to explore the association between urinary iodine excretion ...
