Abstract

Authors' conclusions: our results show the importance of adequate iodine status during early gestation and emphasize the risk that iodine deficiency can pose to the developing infant, even in a country classified as only mildly iodine deficient. Iodine deficiency in pregnant women in the UK should be treated as an important public health issue.

Reviewers' commentary: In this study, the children of women with mild to moderate iodine deficit in the first trimester of pregnancy have lower scores in verbal intelligence quotient (IQ) and reading performance at age 8-9 years. However, the strength of the association is weak and some factors that may have influenced the results have not been taken into account.
