通过尿碘含量对碘缺乏病易伤人群的碘营养水平的调查．结果：新生儿尿碘下限值达到美国标准200μg／L者只有3．8％。0．5～1岁婴儿尿碘值有68．9％达到100μg／L下限值；1～3岁幼儿有58．6％达到120μg／L；4～6岁儿童有85．8％达到140μg／L。8～10岁儿童尿碘中位数为151．8μg／L达到我国碘缺乏病消除标准。孕妇尿碘值达到175μg／L下限值者占22．1％。哺乳妇女尿碘值达到200μg／L者占1．6％。以上各组人群中均有一定比例的人有碘营养水平低下。
Investigation of iodine nutrition of iodine deficiency patients vulnerable to urinary iodine. Results: Neonatal urinary iodine limit of only 3.8% of the US standard 200μg / L. The urinary iodine value of 0.5 to 1 year-old infants reached the lower limit of 100 μg / L, while the urinary iodine value of 68.9% reached 120 μg / L in 58.6% of children aged 1-3 years and 140.8 μg in 85.8% of children aged 4 to 6 years / L. The median urinary iodine of children aged 8 to 10 years was 151.8μg / L, which reached the standard of elimination of iodine deficiency disorders in our country. Pregnant women urinary iodine value reached 175μg / L, the lower limit accounted for 22.1%. In lactating women, urinary iodine value reached 200μg / L, accounting for 1.6%. All of the above groups of people have a certain percentage of people have low levels of iodine nutrition.
