Abstract

Objective To understand the iodine nutrition status of school children aged 8-10 years in Luohu District of Shenzhen City, so as to provide basis for scientific iodine supplement for special population in the district. Methods From 2018 to 2022, edible salt and random urine samples of non-boarding students aged 8-10 years Luohu District of Shenzhen were collected for iodine content detection and follow-up investigation. Meanwhile, thyroid volume was measured by ultrasonography. Results From 2018 to 2022, a total of 1 000 salt samples were tested, of which the median salt iodine content was 26.2 mg/kg, the edible rate of iodized salt was 90.3%, and the edible rate of qualified iodized salt was 84.0%. The median urinary iodine of children was 201 μg/L. The proportion of iodine undernutrition in children who consumed qualified iodized salt was 11.0%, and the proportion of iodine undernutrition in children who consumed unqualified iodized salt was 35.0%. The goiter rate ranged from 1.0% to 2.5% between 2018 and 2022. Conclusion The rate of qualified iodine coverage and goiter of children aged 8-10 in the district reached the national standard for iodine deficiency disorders elimination, the median urinary iodine reached the appropriate level of iodine, and the iodine nutritional status was good. The iodine nutritional status of children who eat qualified iodized salt is better than that of children who eat unqualified iodized salt.
