【摘要】 目的了解北京市怀柔区学龄儿童碘营养状况,为控制儿童碘缺乏病的发生提供参考依据。方法按照地理分布采用随机抽样方法抽取怀柔区8~10岁儿童进行调查,尿碘含量检测采用砷铈催化分光光度测定方法。结果 400名学龄儿童尿碘中位数为184.1μg/L。其中<50μg/L的12人,占总检测者的3%;50~<100μg/L的27人,占6.75%;100~<300μg/L的335人,占83.75%;≥300μg/L的26人,占6.5%;结论怀柔区学龄儿童尿碘含量在国家消除碘缺乏病标准范围之内,但对郊区部分儿童仍需科学补碘和控碘。更多还原

【Abstract】 [Objective]To understand the iodine nutritional status of school-age children in Huairou District of Beijing,provide references for controlling the occurrence of iodine deficiency disorders in children. [Methods]According to the geographical distribution,children aged 8-10 years old were collected from Huairou District by random sampling method. The content of urinary iodine was determined As3+-Ce4+catalytic spectrophotometry. [Results]The median urinary iodine of 400 school-age children was184.1 μg/L. Among them,there were 12 children whose urinary iodine content was lower than 50 μg/L,27 children with the urinary iodine content of 50-100 μg/L,335 children with the urinary iodine content of 100-300 μg/L,and 26 children whose urinary iodine content was higher than 300 μg/L,which accounted for 3%,6.75%,83.75% and 6.5%,respectively. [Conclusion]The urinary iodine content of school-age children in Huairou District meets the national criteria for elimination of iodine deficiency disorders.But the proportions of school-age children whose urinary iodine content is lower or higher are larger relatively,so it is necessary to take the scientific measure to control iodine intake among theses populations.更多还原
