Abstract: Iodine is an essential trace element for growth and development of fetus. More and more surveys currently show that the urinary iodine level of pregnant women is between 100 - 149 μg/L, which is lower than the level recommended by the World Health Organization (WHO). Under this level of iodine nutrition, different investigations have shown different effects on thyroid function of pregnant women, and the impact on growth and development of the fetus requires long-term objective evaluation. At present, there are three aspects: development, intelligence quotient (IQ), and psychological behavior. There are not many studies on comprehensive evaluation. This article combs the related published research to provide a reference for further clarifying the influence of iodine nutrition level during pregnancy on thyroid function of pregnant women and the growth and development of their offspring.
