Abstract:
Objective To explore current situation of iodine deficiency disorders(IDD) and iodine nutrient level by analyzing monitoring data of IDD from children aged from 8 to 10 and pregnant women in Wuhai City in 2017,so as to provide basis for the prevention and control of IDD. Methods Our surveillance points were located in Haibowan District, Wuda District, Hainan District of Wuhai City. Samples of salt and human urine were collected from 200 children aged 8 to 10 and 100 pregnant women at random. Urine iodine concentration and salt iodine concentration were measured. Thyroid volume was determined by B-ultrasound. Results There were 10 children diagnosed as thyroid goiter. Children’s Goiter rate in this area was 1.67%.The averaged covering rate of eating iodine among children reached 99.56%, their acceptance rate of iodized salt was 12.7%. Median of salt-iodine was 21.7 mg/kg. Median of urinary iodine(MUI) for children was 204.5 μg/L. The percentage of children whose urinary iodine was less than 100 μg/L and 50 μg/L was 12.7% and 2.2%, respectively. Median of urinary iodine in boys was 224.0 μg/L, which was higher than in girls(191.5 μg/L), the difference was statistically significant(P=0.004). Median of urinary iodine in pregnant women was 145.8 μg/L. Pregnant women whose urine iodine below 150 μg/L accounted for 51.7%. The MUI in pregnant women during the first trimester was 115.5 μg/L. Pregnant women during the first trimester whose urine iodine below 150 μg/L accounted for 62.0%. Conclusions The iodine nutrition condition in children is basically normal, while iodine nutrition deficiency exist in pregnant women in this area. We should particularly enhance monitoring urinary iodine for pregnant women during the first trimester to reduce iodine deficiency.
