摘要
目的调查与了解淮安市学龄儿童尿碘与家庭盐碘水平及其分布,评估本市学龄儿童碘营养状况并为地区碘缺乏病防治提供参考依据。方法 2016年,在淮安市采用随机抽样的方法,选取8~10岁年龄组学龄儿童为调查对象,采集并检测尿样和家庭食用盐中碘含量。结果共收集尿样1 600份,尿碘中位数为195.5μg/L,男200.6μg/L、女190.4μg/L。尿碘频数分布与性别和年龄分组差异无统计学意义(P>0.05)。分析进一步发现,尿碘含量<50μg/L占3.7%、分布于50~100μg/L占10.3%。尿碘含量低于适宜水平占13.9%,高于适宜水平占48%。检测1 600份食盐,含碘均值为(24.9±3.7)mg/kg,中位数为24.9mg/kg,食盐碘合格率98.9%、合格碘盐食用率98.6%,非碘盐食用率0.3%。结论淮安市学龄儿童尿碘中位数相对适中,满足消除碘缺乏病的相关指标。
Objective To investigate and understand the levels and distribution of urine iodine and household salt iodine among school-age children in Huai′ an city,to assess the iodine nutrition status of school-age children in this city and to provide reference for the prevention and control of iodine deficiency disorders in this area. Methods In 2016,a random sampling method was used in Huai′an City to select school-age children aged 8-10 years old as subjects to collect and test the iodine content in urine samples and household salt. Results A total of 1 600 urine samples were collected.The median urinary iodine was 195.5 μg/L,200.6 μg/L for boys and 190.4 μg/L for girls.The frequency distribution of urinary iodine had no significant difference with sex and age groups （ P 〉0.05 ）.Further analysis showed that urinary iodine content 〈50 μg/L accounted for 3.7% and distribution in the range of 50-100 μg/L accounted for 10.3%.Urinary iodine content was 13.9% lower than the appropriate level and 48% higher than the appropriate level.1 600 parts of salt were detected,the average iodine content was （24.9±3.7） mg/kg,the median was 24.9 mg/kg,the salt iodine pass rate was 98.9%,the qualified iodized salt consumption rate was 98.6%,and the non-iodized salt consumption rate was 0.3%. Conclusion The median urinary iodine of school-age children in Huai′ an city is relatively moderate,which meets the relevant indicators for eliminating iodine deficiency disorders.
