Physical and Chemical Laboratory, Luohu District Center for Disease Control and Prevention, Shenzhen(518000), Guangdong Province, China

摘要

摘要: 目的了解深圳市罗湖区8~10岁儿童碘营养状况，以便为辖区内特殊人群补碘提供更科学的依据。方法 2018—2022年在深圳市罗湖区抽取8~10岁非寄宿学生家中食用盐和随机尿样开展碘含量检测，并做随访调查；同时开展B超法测量甲状腺容积。结果 2018—2022年共检测盐样1 000份，其中盐碘含量中位数为26.2 mg/kg，碘盐的食用率为90.3%，合格碘盐的食用率为84.0%。儿童尿碘中位数为201.0 μg/L，食用合格碘盐儿童的碘营养不足占比11.0%，食用不合格碘盐儿童的碘营养不足占比35.0%。2018—2022年甲状腺肿大率范围为1.0%~2.5%。结论罗湖区8~10岁儿童合格碘盐食用率、甲状腺肿大率均满足国家消除碘缺乏病的标准，尿碘中位数达到了碘适宜水平，碘营养状况良好。食用合格碘盐儿童的碘营养状况优于食用不合格碘盐儿童的，应引起重视。

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.
