Iodine deficiency
Another common IDD prevalent in China is Kashin-Beck disease. A particular outbreak in Tibet was recorded as occurring from lack of iodine. Kashin-Beck is a bone deformity endemic. Iodine deficiency, hypothyroidism, and low serum concentrations of thyroxine-binding globulin were significantly related to Kashin–Beck disease. Iodine supplemented irrigation water in combination to iodized salt helps in reducing the neonatal and infant mortality rates. The province of Xinjiang suffers severely from IDDs and in 1993, started the use of potassium iodate in combination with irrigation water. Irrigation water is widely used and accessible to all households making it the predominant solution in reducing micronutrient deficiencies for Xinjiang.
