What are the causes of iodine deficiency disorders in children

Environmental factors: the epidemic is caused by iodine deficiency in soil in most parts of the world, especially in glacial erosion zones and flood plains. The destruction of soil by human activities, deforestation, soil erosion, also caused environmental iodine deficiency. There are many reports about iodine deficiency in mountainous areas. Endemic goiter in China is also mostly distributed in mountainous areas, mainly due to the mountain slope, rain erosion, iodine loss from the soil. Iodine deficiency in Sanjiang Plain of Heilongjiang Province in Northeast China may be caused by frequent flooding in history and active movement of groundwater.

The incidence rate of iodine deficiency disorders is low in some areas. In China's Xi'an, Baoji, Shiquan and Lantian, iodine content in drinking water is low, and the incidence rate of goiter is also high.

Fetal iodine deficiency: during pregnancy, if the intake of iodine is insufficient, the concentration of inorganic iodine ion in plasma is reduced, T3 and T4 produced by thyroid gland are less, T3 and T4 in blood are reduced, so that T3 and T4 through placenta are reduced, which can not meet the needs of the fetus. A series of obstacles appear in the growth and development of the fetus, and the central nervous system first presents symptoms.
