摘要
目的了解食用碘盐含量标准下调以后重点人群中8岁~10岁儿童的碘营养状态。方法采用一次性采取尿样,由渭南市疾病预防控制中心实验室,按照WS/T 107-2006中过硫酸铵消化-砷铈催化分光光度法进行尿碘含量检测。监测人群为8岁~10岁儿童。结果 8岁~10岁儿童尿碘中位数为297.8μg/L;男生与女生尿碘水平差异无统计学意义,但男生尿碘水平稍高于女生;11个县(市、区)儿童尿碘中位数为247.9μg/L^365.5μg/L,经方差分析,P<0.05,差异有统计学意义。结论 8岁~10岁儿童尿碘水平达到国家消除碘缺乏病的指标要求,但尿碘超过足够量情况比较严重,说明食盐碘含量下调初期,市场上高浓度碘盐存在量较大,需要继续加强监测评估。
Objective To investigate the status of iodine nutrition for key population of 8 ～ 10 year- old children after down-regulation of content standards for edible iodized salt. Methods Took urine samples in one time,and the urinary iodine contents in urine samples were detected by using ammonium persulfate digestion arsenic- cerium catalytic spectrophotometry according to WS / T 107- 2006. The monitoring population was the children aged 8 to 10 years old. Results The median of urinary iodine content was 297. 8 μg / L. There was no statistical difference for the status of urinary iodine between boys and girls regardless that boys＇ status of urinary iodine was slightly higher than girls＇. The median of urinary iodine content in 11 counties varied from 247. 9 μg / L to 365. 5 μg / L which exhibited a significant difference with P〈0. 05 by ANOVA. Conclusion The status of urinary iodine for 8 ～ 10 year- old children reached the national requirement for eliminating iodine deficiency disorders. However,the excess of urinary iodine content was serious which indicated that there was still high concentration iodized salt in markets in the initial stage of down- regulation for edible iodized salt,and enhanced the monitoring for iodine content in edible salt still needed to be enhanced.
