Iodine affects normal growth, development and metabolism of human body by participating in the synthesis of thyroid hormones. Iodine deficiency affects nearly 1.9 billion people worldwide and it is one of the health problems of global concern. As a special group, pregnant women are the focus group of iodine deficiency. Iodine deficiency during pregnancy will not only lead to thyroid dysfunction, endemic cretinism, but also irreversibly affect fetal brain development, resulting in infant mental retardation and growth retardation. This article summarizes the research progress of iodine deficiency during pregnancy, focusing on the hazards and evaluation index of iodine deficiency during pregnancy, and provides reference for future research priorities of iodine deficiency during pregnancy.
