Abstract Background: The global effort to prevent iodine deficiency disorders through iodine supplementation, such as universal salt iodization, has achieved impressive progress during the last few decades. However, iodine excess, due to extensive environmental iodine exposure in addition to poor monitoring, is currently a more frequent occurrence than iodine deficiency. Iodine excess is a precipitating environmental factor in the development of autoimmune thyroid disease. Objective: To evaluate the urinary iodine level as a marker of iodine status in pregnant women in 3rd trimester and assess its relation to thyroid functions. Methods: This Cross Sectional Study was conducted on 100 subjects with their ages ranging from 18-35 years old , pregnant females , at the third trimester , selected from Obstetric Out- patient Clinic of Ain shams University Hospitals . Samples were collected from participants in cairo , during the Spring and Summer from March to Novomeber. Results: In our study, there was a significant negative correlation between Urinary Iodine level and TSH as Iodine difficient group has the Highest TSH, and the Highest Thyroid Volume, as there was a significant negative correlation between Urinary Iodine level and Thyroid Voulme. Conclusion: TSH level and Thyroid Volume were significantly higher in Iodine difficient group than Excess iodine group, And FT4 level was lower in Iodine difficient group than excess iodine group. |
