Mild- to moderate iodine deficiency in pregnancy and early age and risk of impaired neuropsychological development - project description

Published Updated


The aim of this project was to explore the associations between maternal iodine intake in pregnancy from food and supplements and markers of child brain development in The Norwegian Mother and Child Cohort Study


Summary

Iodine is an integral part of the thyroid hormones that are essential in foetal brain development and iodine deficiency is the world’s most prevalent, yet easily preventable, cause of brain damage. Severe iodine deficiency in pregnancy has detrimental effects on foetal neurodevelopment, whereas less is known about the potential consequences of mild-to-moderate iodine deficiency. The aim of this project was to explore the associations between maternal iodine intake in pregnancy from food and supplements and markers of child brain development in The Norwegian Mother and Child Cohort Study (MoBa). Additionally, in a subsample of around 3000 women, we aimed to examine associations between maternal iodine status and maternal thyroid function. Four papers have been published in this project so far and the results indicate that low maternal iodine intake is associated with impaired neurodevelopmental outcomes in children at 3 and 8 years.
