Analysis of iodized salt consumption and urinary iodine monitoring in school-aged children in Fuxin
阜新市学龄儿童家庭食用碘盐及尿碘监测结果分析

摘要

目的 评估阜新市学龄儿童家庭碘盐摄入与尿碘水平，分析碘营养状况，为防控碘缺乏病提供依据。方法 于2023年5月在阜新市随机抽取800名6～12岁儿童，采集家庭碘盐与晨尿样本，分别采用碘量滴定法和砷铈催化分光光度法检测，依据《碘缺乏病监测方案（2020年版）》进行评价，统计分析采用SPSS 26.0。结果 800份食盐中合格碘盐占94.25%，碘含量中位数26.7 mg/kg；尿碘中位数198.4 μg/L，处于适宜水平。合格碘盐组尿碘水平显著高于不合格组（Z=4.317，P＜0.001）。结论 阜新市学龄儿童碘盐覆盖率高，碘营养总体适宜，但仍有部分家庭未使用合格碘盐，需持续加强碘盐管理和重点人群监测。

Abstract

Objective To evaluate household iodized salt intake and urinary iodine levels among school-aged children in Fuxin, and to assess iodine nutrition for iodine deficiency disorder prevention.
Methods In May 2023, 800 children aged 6–12 years were randomly selected. Household salt and morning urine samples were tested using iodometric titration and arsenic–cerium catalytic spectrophotometry, respectively, following the Iodine Deficiency Disorder Monitoring Program (2020 edition). Data were analyzed with SPSS 26.0.
Results Qualified iodized salt accounted for 94.25% of 800 samples, with a median iodine content of 26.7 mg/kg. Median urinary iodine concentration was 198.4 μg/L, within the adequate range. Children in households with qualified iodized salt had significantly higher urinary iodine than those without (Z=4.317, P<0.001).
Conclusion   Iodized salt coverage in Fuxin is high and iodine nutrition is generally adequate, but continued management and monitoring are needed for families not consuming qualified iodized salt.
