学龄前儿童尿碘水平监测分析

Monitoring and analysis for urine iodine level on preschoolers

目的:对学龄前儿童进行尿碘水平检测,早期监控碘缺乏病。方法:采用随机抽样法,抽取8、9、10岁三个年龄组学龄前儿童各450例,然后采用砷铈催化分光光度法测定尿碘水平。结果:此次共调查学龄儿童1350例,尿碘均值(309.1±32.7)mg/L。表明现阶段的碘干预措施已能满足学龄儿童生理需要,普及碘盐后出生的学龄儿童已不再缺乏碘营养,进而保证了阶段性消除IDD成果。三个年龄组性别间和各年龄组间学龄儿童尿碘均值均无显著差异(P﹥0.05),说明上述三个年龄组儿童一致性较高,代表性强,碘营养和排泄水平不存在群体差异。结论:抽样显示三个年龄组儿童尿碘水平正常。

Objective：To preschool children early detection,urinary iodine level monitor idd.Methods：Using random sampling method,the extraction 8,9,10 years old three age groups preschool children,then the various 450 cases of arsenic cerium catalytic spectrophotometry urine iodine level.Results：The total survey school-age children 1350 patients,urine iodine 309.1＋mean （32.7） mg/L.The iodine intervention measures that the already can satisfy the school-age children DianYan physiological needs,popularize the school-age children born after already no longer lack iodine nutrition,ensuring that the phased eliminating IDD results.Three age groups between the sexes and every age group mean between school-age children urine iodine there were no significant difference （P﹥0.05）,indicating that the above three age groups of children,strong consistency is higher,representative iodine nutrition and discharge level does not exist population differences.Conclusion：Sampling shows three age groups children urine normal levels iodine.
