Of these, the highest rate of non-iodized edible salt was in 2017 (χ 2 = 75.38, P < 0.05), and with the lowest consumption rate of qualified iodized salt (χ 2 = 56.52, P < 0.05). Totally 829, 891 and 881 urine samples were tested for 8 - 10 years of children, and the medians of urine iodine were 195.8, 243.0 and 164.8 μg/L, respectively.
