摘　　要：目的对兰州市2016年(8~10)岁儿童碘营养水平进行分析,为改善兰州市儿童碘营养状况提供参考。方法按照分层抽样的方法,从兰州市八区县中分别随机抽取(8~10)岁儿童200名,调查其尿碘水平,以及居民碘盐覆盖和合格情况。尿碘测定采用砷铈催化分光光度法,盐碘采用直接滴定法。结果兰州市(8~10)岁儿童,尿碘中位数为203.85μg/L,尿碘小于100μg/L的儿童占16.1%,(100~300)μg/L者占比最大,为62.2%。经非参数Kruskal-Wallis秩和检验,不同区县尿碘中位数比较差异有统计学意义(H=60.655,P<0.05)。食盐碘含量中位数为23.00 mg/kg,经非参数Kruskal-Wallis秩和检验,不同区县盐碘中位数比较差异有统计学意义(H=263.231,P<0.05)。居民总碘盐覆盖率为98.5%,碘盐合格率为89.6%,略低于居民合格碘盐食用率应大于90%的标准。结论 2016年兰州市(8~10)岁儿童碘营养状态较适宜,尿碘水平在正常范围内,有部分区县盐碘合格率较低,应提高盐碘的合格率。Objectives To analyze the urinary iodine level of children aged 8~10 years in Lanzhou in 2016, and provide reference for improving the iodine nutritional status of children. Methods Based on the stratified random sampling method, 200 children aged 8~10 were selected from eight counties in Lanzhou to investigate the urinary iodine level of children, the coverage of iodized salt in local residents and the qualification of iodized salt. The level of urinary iodine was measured by arsenic cerium catalytic spectrophotometry assay, and the iodine in salt was detected by direct titration method. Results The median of urinary iodine concentration in school-aged children in Lanzhou was 203.85 μg/L, the difference of urinary iodine among eight counties was statistically significant （H=60.655, P〈0.05）. The median of iodine content in salt was 23.00 mg/kg, the difference among eight counties was statistically significant （H=263.231, P〈0.05）. The coverage rate of iodized salt was 98.5%, but the consumption rate of qualified iodized salt was 89.6%, which was lower than the standard limit of the eligible iodine consumption rate （more than 90%） for residents. Conclusions The iodine nutritional status of 8~10 year-old children in Lanzhou in 2016 was appropriate, the urinary iodine level was in the normal range. The qualified rate of iodized salt in some counties was lower than that of the national standard limit, more attention should be paid to improve the qualification of iodized salt.
