Iodine Nutrition during Pregnancy, Lactation and Early Life

Dear Colleagues,

Iodine is an essential micronutrient, which is required for thyroid hormones, which are responsible for the control of growth and development. Iodine deficiency can result in a range of adverse health conditions known under the collective term ‘Iodine Deficiency Disorders’ (IDD). The most recognised condition is goitre, which occurs when hypothyroidism results in the enlargement of the thyroid gland. However, the brain and the central nervous system are especially vulnerable to thyroid hormone deficiency during pregnancy and early life. Exposure of the foetus to severe iodine deficiency during pregnancy can result in cretinism, characterized by severe mental impairment and adverse effects on growth and development. However, research suggests that even mild-to-moderate iodine deficiency during pregnancy can result in cognitive impairment in the offspring. Conversely, excessive iodine intake can also adversely affect thyroid function. It is essential that women and their infants have optimal iodine intake to prevent lifelong consequences.

This Special Issue will bring together research on iodine status during pregnancy, breastfeeding and infancy and its effects on health outcomes.
