The median of urinary iodine in 623 children aged 8 to 10 years old was 221.34 μg/L and the thyroid enlargement rate was 0.48%(3/623). The median of urinary iodine in 346 pregnant women was 159.52 μg/L. Conclusion The iodine nutrition of children aged 8 to 10 years old and pregnant women of Dehong State is appropriate in 2017.
