ارزیابی سطح هورمون محرک تیروئید و ید دفعی ادرار در زنان باردار شهرستان ارومیه
Authors
Abstract:
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 participants from urban and rural population were 41.6% (n=223) and 58.4% (n=283). Random urine and blood samples were collected for the analysis of UIE and TSH, respectively. Results: The overall median UIE was 74 μg/L and 86.4% of women had iodine deficiency (ID) as defined by UIE < 150. The respective levels for urban and rural populations were 76 μg/L vs. 64 μg/L and 88.5% vs. 83.3%. Median TSH as a whole was 0.8 mIU/L whilst those for urban and rural subjects were 1 mIU/L and 0.7 mIU/L. No correlation was seen between UIE and TSH levels. Conclusions: Our data reveals that sever ID is present in 33% of the subjects during the first trimester and that TSH levels are 12-64% lower than those reported for with adequate or more than adequate iodine intake regions in Iran. This preliminarily result suggest that whole body iodine stores is probably adequate to prevent hypo-thyroxinemia during early pregnancy in regions with mild to moderate iodine deficiency.

Background & Aims: Iodine as an essential element is required for biosynthesis of thyroid hormones as well as for the development of the nervous system of the fetus. Therefore, the consumption of an extra dose of iodine ranging from 150-250 µg/day has been recommended for women planning a pregnancy or at early stage of maternity by world health organizations. This study was designed to evaluate...

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...

مقدمه: دریافت ید کافی برای سنتز و ترشح مقادیر کافی هورمونهای تیروئید از غدهی تیروئید ضروری است. تشکیل هورمونهای تیروئید وابسته به در دسترس بودن مقادیر کافی از ید اگزوژن است. در مطالعههای جمعیتی اندازهگیری یک نمونهی تصادفی از ید ادرار فرد، شاخصی برای تعیین دریافت ید نمیباشد. میانهی ید ادرار تصادفی با توجه به دریافت متفاوت ید به صورت روزانه و با توجه به قدرت ذخیرهسازی غدهی تیروئید به ن...
