Results A total of 1,024 students were collected during the five years. Nine patients with grade I goiter were found, with an average rate of 0.88%. A total of 993 patients with urinary iodine and a median urinary iodine of 229.8 μg / L were monitored. Salt of 1 009 households, of which 928 were qualified iodized salt, iodized salt rate was 91.97%, 8 non-iodized salt, non-iodized salt rate was 0.79%, iodized salt coverage was 99.21%. A total of 509 women of gestational age were recruited in 5 years. One degree of goiter was found and the average rate of goiter was 0.20%. A total of 509 urinary iodine and a median urinary iodine of 240.98μg / L were monitored. 495 salt households, of which 470 qualified iodized salt, iodized salt pass rate of 94.95%, iodized salt coverage of 100%. Conclusion The iodized salt prevention and treatment of iodine deficiency disorders in Zhangjiakou City, the effect is significant, urinary iodine, salt iodine and goiter of goat three indicators reach the national standard of iodine deficiency disorders elimination, the future continue to take measures of local conditions, scientific iodine control methods to consolidate iodine Lack of disease prevention and control results.
