不同干预措施对缺碘地区8~10岁儿童尿碘水平的影响

目的了解不同干预措施对缺碘地区8~10岁儿童尿碘水平的影响。方法在不同时期对8~10岁学龄儿童分别采取碘盐干预、碘盐加碘油丸干预、综合干预等干预措施,用砷铈催化分光光度方法检测儿童尿样,观察不同干预措施对儿童尿碘水平的影响。结果干预前儿童尿碘水平较低,未达到国家碘缺乏病消除标准要求;碘盐干预后儿童尿碘水平提高,达到了国家碘缺乏病消除标准要求;碘盐加碘油丸干预后,儿童尿碘水平进一步提高,尿碘中位数在适宜范围;采取综合干预后,稳固了儿童尿碘水平,尿碘中位数始终处在较适宜范围。不同干预阶段尿碘水平比较,差异有统计学意义（P〈0.01）。结论以碘盐干预为主的综合干预可提高和稳固儿童尿碘水平,是缺碘地区改善儿童碘营养水平的有效措施。

Effects of different intervenes on the urinary iodine level in the children aged 8-10 in iodine-deficient areas

Objective To find out the effects of different intervenes on the urinary iodine level in the children aged 8-10 in iodine-deficient areas. Methods At different times, we took different intervenes in the school children aged 8-10, such as iodized salt intervention, iodized salt with iodized oil intervention, synthesis intervention and so on. With arsenic cerium catalytic spectrophotometric method for testing children＇s urine, we observed the effects of different interventions on intervention, Children＇s urinary iodine level was low, the children＇s urinary iodine level. Results Before the and it didn＇t meet the standard of eliminating national Iodine Deficiency Disorders. However, after the iodized salt intervention, children＇s urinary iodine level was improved, and it reached the standard of eliminating national Iodine Deficiency Disorders. After the iodized salt with iodized oil intervention, the children＇s urinary iodine level had a further improvement, median urinary iodine was in a suitable range. Adopting comprehensive intervention reinforces children＇s urinary iodine levels and the median urinary iodine was always in the appropriate range. The differences of urinary iodine level indifferent intervention stages had statistical significance（P〈O.O1）. Conclusion It is an effective measures to improve the level of children＇s iodine nutrition in iodine-deficient area with iodized salt intervention.
