Objectives: The fetus is dependent on maternal thyroid hormones during pregnancy and an adequate thyroid function during pregnancy is essential for the normal brain development. The effects of subclinical hypothyroidism during pregnancy are poorly known. The present study assesses the association between thyroid hormones and thyrotropin in healthy pregnant women from the general population, and the neurodevelopment of their children at the age of 14 months.<p class="abstex...

Objective: An adequate thyroid function during pregnancy is essential for the normal brain development of the foetus, and some organochlorine compounds (OCs) can interfere with the thyroid system. The objective of the present study was to evaluate the association between exposure to some OCs and thyroid function in pregnant women from two different areas in Spain, as well as to investigate the potential confounding effect of iodine intake.Methods: Thyroi...

Introduction: The fetus is the most vulnerable to severe iodine deficiency and hypothyroidism during pregnancy. Severe iodine deficiency and hypothyroidism during pregnancy have long been known to be associated with neurologic deficits and mental retardation The effects of mild iodine deficiency and subclinical hypothyroidism are poorly known. The present study assesses the association between thyroid hormones and urinary iodine concentration (UIC) in healthy pregnant women an...

Background: Low maternal urinary iodine concentration (UIC) during pregnancy has been associated with lower child IQ and differences in brain morphology. However, UIC is highly variable as it is a reflection of 24-h urinary intake rather than long-term iodine status. Thyroglobulin (Tg) might be a more sensitive biomarker of the long-term maternal iodine status.Aim: To study whether maternal Tg is associated with maternal and newborn thyroid hormone conce...
