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。
Objective To understand the iodine nutrition status of school-aged children in Huairou District of Beijing, and to provide a reference for controlling iodine deficiency disorders in children. Methods According to the geographic distribution, children aged 8 to 10 years in Huairou district were randomly sampled for urinary iodine determination using arsenic and cerium catalytic spectrophotometry. Results The median urinary iodine of 400 school-age children was 184.1 μg / L. Among them, 12 were <50 μg / L, accounting for 3% of the total; 27 were 50 ~ <100 μg / L, accounting for 6.75%; 335 were 100 ~ <300 μg / L, accounting for 83.75%; 26, accounting for 6.5%; Conclusions The urinary iodine content of school-age children in Huairou District is within the national standard of eliminating iodine deficiency disorders, but some children in the suburbs still need scientific iodine supplementation and iodine control.
