摘要
目的监测易县学龄儿童不同时期尿碘水平,观察不同干预措施的干预效果,为碘缺乏病防治工作提供科学依据。方法 1993—2012年间,每年在易县按东西南北中5个方位各随机抽取1个乡镇,每个乡镇随机抽取1所小学,每所小学随机抽取8~10岁儿童尿样20人份以上,采用尿碘砷铈催化分光光度法测定尿碘含量。结果随着补碘干预及碘盐干预基础上综合干预措施的实施,易县学龄儿童尿碘水平逐渐提高,并达到国家碘缺乏病消除标准,山区和平原儿童尿碘水平差异性逐渐消失。不同年龄、性别、民族儿童尿碘水平分布在各阶段差异均无统计学意义（P值均〉0.05）。结论以碘盐干预为基础的综合干预措施可改善和提高学龄儿童碘营养水平,是防治碘缺乏病行之有效的方法,但应注意高碘摄入风险。
Objective To monitor urinary iodine levels of school-aged children in different periods in Yixian County,to observe intervention effects of different interventions,and to provide a scientific basis for the prevention and control of iodine deficiency disorders.Methods Five towns were selected at random in the range of the county according to azimuth（east,west,south,north and center）.One elementary school was randomly chosen in every town of the five.And 20 urine samples of 8-10 years old children were randomly drawn in every school.The iodine contents were determined through arsenic cerium catalytic spectrophotometric method.Different intervention phase of school-age children urinary iodine levels were compared during 1993-2012.Results Along with the iodine intervention and implementation of the comprehensive interventions on the basis of iodine salt supplementation,urinary iodine levels of Yixian school-age children gradually improved,and reached the national iodine deficiency disorders elimination standards,urinary iodine level of Mountains and plains differences gradually disappear.There was no statistical significant difference of urinary iodine levels in the various stages among the children of different age,gender and ethnicity（P 0.05）.Conclusion The iodine salt intervention based interventions can improve and enhance the level iodine nutrition of school-age children,and it is an effective way to prevent and control iodine deficiency disorders,meanwhile,the risk of excessive iodine intake should not be ignored.
