内蒙古自治区2011年8～10岁儿童碘营养现状

Iodine nutritional status of children aged 8 to 10 in Inner Mongolia in 2011

目的掌握内蒙古8~10岁儿童碘营养状况,为自治区因地制宜、科学补碘提供参考依据。方法在内蒙古自治区的12个盟（市）,70个旗（县、区）,每个旗（县、区）按东、西、南、北、中5个方位各抽取100名8~10岁儿童（男、女各半）尿样进行尿碘测定。结果共检测8~10岁儿童尿样6993份,尿碘中位数为249.0ug/L,〈50ug/L的占1.5%,50~99ug/L的占4.7%,100~199 ug/L的占26.5%,200~299ug/L的占32.4%,≥300ug/L的占34.8%。结论内蒙古自治区8~10岁儿童碘营养处于充足状态,居民食用盐加碘浓度还有下调的空间。

Objective To study the iodine nutritional status of children aged 8 to 10 in Inner Mongolia,and to provide a scientific basis for supplementation of iodine. Methods 100 children aged 8 to 10（ half male and female） were randomly collected in each 70 towns according to their sub-area position of east,south,west,north and center sub-areas and were tested urine iodine. Results The median urinary iodine of 6 993 children aged 8 to 10 was 249. 0 μg /L, with 50 μg /L accounted for 1. 5%, 50 ~ 99 μg/L accounted for 4. 7%,100 ~ 199 μg/L accounted for 26. 5%, 200 ~ 299 μg/L accounted for 32. 4%,and ≥300 μg/L accounted for 34. 8%. Conclusions The iodine nutrition in children aged 8 to 10 in Inner Mongolia was at adequate level, and it was necessary to lower iodine concentration of edible salt in residents.
