Impact of Nutritional Iodine Optimization on Rates of Thyroid Hypoechogenicity and Autoimmune Thyroiditis: A Cross-Sectional, Comparative Study

Abstract

The current nutritional iodine status in our cohort was within optimal levels and lower than levels found in 2003. The prevalence of autoimmune thyroiditis seems to be decreasing in parallel with a decrease in iodine intake, although we could not reach a definitive conclusion.
