Objective To understand the salt iodine level and iodine nutrition level of Lianxi District residents,and to provide scientific basis for the continuous elimination of iodine deficiency disorders and rational iodine supplement. Methods Forty children aged 8~10 years and 20 pregnant women were selected from five towns in the east,west,south,north and middle of the district.Edible salt and urine samples were collected to detect the content of salt iodine and urine iodine,and the detection results were statistically analyzed.Thyroid examination was performed on the sampled children. Results A total of 300 edible salt samples were tested with a median salt iodine level of 24.0 mg/kg,an iodized salt coverage rate of 96.7%,and a qualified iodized salt consumption rate of 93.7%.The median of urinary iodine in 8~10 years children was 211.4 μg/L,with urinary iodine level＜50 μg/L accounting for 1.0%,＜ 100 μg/L accounting for 14.5%,100~299 μg/L accounting for 56.5%,≥300 μg/L accounted for 29.0%.The median urinary iodine of pregnant women was 160.9 μg/L,with urinary iodine level ＜ 150 μg/L accounting for 46.0%,150-249 μg/L accounting for 32.0%,250~499 μg/L accounting for 19.0%,≥500 μg/L accounting for 3.0%.There was no goiter case in children aged 8-10 years.
