目的客观评价平顶山市不同人群碘营养状况,为适时采取针对性防治措施和科学调整干预策略提供依据。方法在河南省5个县(市)、区选取新婚育龄妇女、孕妇、哺乳期妇女、0~2岁婴幼儿、8~10岁儿童5类人群作为调查对象,每类人群分别随机抽取200份以上尿样,硫酸铵消化-砷铈催化分光光度法测定尿碘水平。结果共采集5类不同人群尿样1 217份,新婚育龄妇女、孕妇、哺乳期妇女、0~2岁婴幼儿和8~10岁儿童的尿碘中位数分别为179.9μg/L、151.9μg/L、145.3μg/L、221.1μg/L和164.9μg/L;其中孕妇尿碘<150μg/L的占48.6%,哺乳期妇女尿碘<100μg/L的占29.1%。叶县孕妇尿碘中位数低于150μg/L,鲁山县0~2岁婴幼儿尿碘中位数处于推荐值的下限边缘。结论平顶山市不同人群的碘营养状况总体水平上是适宜的。部分孕妇和哺乳期妇女及婴幼儿存在碘摄入不足,应引起高度重视。加强健康教育,实施科学补碘,纠正部分人群碘营养偏低状况。
Objective To objectively evaluate the iodine nutrition status of different population in Pingdingshan City and provide the basis for appropriate prevention and treatment measures and scientific adjustment of intervention strategies. Methods In five counties (cities) of Henan Province, five newly-married women of childbearing age, pregnant women, lactating women, infants aged 0 ~ 2 and children aged 8 ~ 10 were enrolled in this study. 200 The above urine sample and ammonium sulfate digestion - catalytic spectrophotometric determination of urinary iodine with arsenic and cerium.

The median urinary iodine of newly married women, pregnant women, lactating women, 0 ~ 2 years old children and 8 ~ 10 years old children were 179.9μg / L, 151.9μg / L, 145.3μg / L, 221.1μg / L and 164.9μg / L; pregnant women, urinary iodine <150μg / L accounted for 48.6%, lactating women urinary iodine <100μg / L accounted for 29.1%. The median urinary iodine of pregnant women in Ye County was less than 150μg / L, and the median urinary iodine of infants aged 0-2 years in Lushan County was at the lower edge of the recommended value. Conclusion The overall iodine nutrition status of different populations in Pingdingshan City is suitable. Some pregnant women and lactating women and infants and young children with inadequate intake of iodine, should cause great attention.
