摘要
[目的]了解黔东南州8～10岁儿童碘营养状况和居民食用盐碘含量,为制定有效的防治措施提供科学依据。[方法]2009年,在黔东南州所辖16县(市)抽取80所小学的8～10岁小学生进行尿碘测定与碘缺乏病知识调查;抽取4680户居民食盐检测碘含量。[结果]检测小学生尿样1600份,尿碘中位数为344.15μg/L,尿碘≥100μg/L、≥300μg/L、≤50μg/L的分别占96.88%、60.88%、0.63%。检测4680户居民的食用盐,碘盐覆盖率为99.83%,碘盐合格率为98.14%,合格碘盐食用率为97.97%,盐碘中位数为31.70mg/kg,碘盐中碘含量超标的占0.15%。[结论]黔东南州各县(市)已经达到消除碘缺乏病标准,部分儿童碘营养水平偏高,碘盐浓度仍有下调空间。
[Objective] To understand the state of the iodized nutrition among children aged 8-10 years and the salt iodine content among residents in Qiandongnan prefecture,to provide scientific evidence for prevention and control of IDD.[Methods]Children aged 8-10 years were sampled to be tested on urinary iodine from 80 primary schools in 16 counties or cities of Qiandongnan prefecture and 4 680 households were sampled to conduct a survey on salt iodine content among residents in Qiandongnan prefecture in 2009.[Results]The medians of urinary iodine content in 1 660 children samples was 344.15 μg/L,the percentage of urinary iodine ≥100 μg/L was 96.88%,in which ≥300 μg/L was 60.88%,the percentage of urinary iodine 50 μg/L were only 0.63%.In 4680 households,the coverage rate of iodized salt was 99.83%,The rate of qualified iodized salt was 98.14%,the intake rate of qualified iodized salt was 97.97%,the mean iodine was 31.70 mg/kg,and the iodized content exceed standard in 0.15% of the iodinated salt samples.[Conclusion]The standards of eliminating IDD have achived in every county or city in Qiandongnan prefecture.the level of the iodized nutrition among some children is higher in Qiandongnan prefecture,the concentration of iodine salt can be used at a lower level.
