目的调查常德地区8～10岁儿童尿碘水平,了解该地区居民的碘营养状况。方法通过人口容量比例概率抽样法(PPS)采集儿童尿样,同时采集食用碘盐,用分光光度法和滴定法分别测定尿样和盐样中碘含量,对测定结果进行统计分析。结果 8～10岁儿童尿碘中位数为364μg/L;经秩和检验,各个县尿碘水平之间差异有统计学意义(P<0.05);男生与女生尿碘水平间差异有统计学意义(P<0.05);其中澧县男、女生尿碘水平间差异有统计学意义(P<0.05)。居民户盐碘均值和合格率分别为23.5mg/kg、97.2%。结论常德地区学龄儿童尿碘水平达到国家卫生部消除碘缺乏病的标准,学龄儿童碘营养状况良好,但仍存在地区和性别差异。
