High Prevalence of Thyroid Disorders in Pregnant Women in a Mildly Iodine-deficient Country: A Population-Based Study

Abstract

The prevalence of thyroid disorders was high, affecting one in six pregnant women in Belgium. Therefore, the iodine status in women needs to be improved and screening for thyroid disease should be performed early in pregnancy. In addition, our data suggest that a median Tg of <20 μg/L may indicate iodine sufficiency in pregnant women.
