Abstract:
Objective:To investigate the iodine nutrition status of children aged 8 to 10 years old in Nanchang City.Methods:From March 2020 to September 2022, 9 counties (districts, administration bureau) in Nanchang City were selected as monitoring points. Each monitoring point was divided into 5 sampling areas according to the east, west, south, north, and middle directions. One township was selected from each area, and 40 non-boarding children aged 8 to 10 years old (age balanced, half male and half female) from one primary school were selected as survey subjects. Edible salt samples from children's homes, as well as a random urine sample were collected to detect salt iodine and urinary iodine level. The thyroid volume of children was also measured.Results:From 2020 to 2022, a total of 5 400 edible salt samples from children's homes were tested, with a median salt iodine level of 24.13 mg/kg. Among them, there were 5 172 qualified iodized salt samples, 168 unqualified iodized salt samples, and 60 non-iodized salt samples. The coverage rate of iodized salt was 98.89% (5 340/5 400), the qualified rate of iodized salt was 96.85% (5 172/5 340), and the consumption rate of qualified iodized salt was 95.78% (5 172/5 400). A total of 5 400 children's urine samples were tested, with a median urinary iodine level of 210.90 μg/L. A total of 2 662 children were examined for thyroid, of which 4 had thyroid enlargement, with an enlargement rate of 0.15% (4/2 662).Conclusion:The overall iodine nutrition of children aged 8 to 10 years old in Nanchang City is at a super appropriate level, and the thyroid enlargement rate meets the national standard (< 5%).
