Abstract:
Objective:To investigate the iodine nutritional status of children aged 8-10 years in Jilin Province.Methods:From March 2021 to September 2023, in accordance with the requirements of the "Monitoring Plan for Iodine Deficiency Disorders in Jilin Province", monitoring for iodine deficiency disorders was carried out among children aged 8-10 years in 60 counties (cities, districts) of Jilin Province. Salt samples from children's homes and one random urine sample were collected to test salt iodine and urinary iodine. Thyroid B-ultrasound examination was performed on children to calculate the goiter rate.Results:From 2021 to 2023, a total of 36 028 household salt samples were tested, with a median salt iodine of 23.9 mg/kg and a consumption rate of qualified iodized salt of 96.3% (34 705/36 028). A total of 36 028 children's urine samples were tested, with a median urinary iodine level of 179.3 μg/L. The median urinary iodine levels of children in each year were 180.0, 177.2 and 181.2 μg/L, respectively ( n = 12 014, 12 006, 12 008). The median urinary iodine levels of children aged 8, 9 and 10 years were 182.2, 182.1 and 172.8 μg/L, respectively ( n = 10 238, 16 343, 9 447). The median urinary iodine levels of boys and girls were 182.8 and 176.3 μg/L, respectively ( n = 18 227, 17 801). A total of 12 006 children underwent thyroid examination, 41 children were detected with goiter, with a goiter rate of 0.34%. Conclusion:From 2021 to 2023, the consumption rate of qualified iodized salt ( > 90%), urinary iodine (100-< 200 μg/L) and goiter rate ( < 5%) of children in Jilin Province meet the national iodine deficiency disorders elimination standards.
