中文摘要：

目的：评价甘肃武威3岁以下儿童碘营养和生长发育状况，为进一步调整食盐加碘量和合理指导婴幼儿补碘提供科学依据。方法：随机抽取甘肃省0—3岁儿童98名，采集1个月内连续2次随意尿样，检测尿碘含量，并测量身高、体重，计算z分值评价儿童生长发育状况。结果：儿童1月内连续2次随意尿样尿碘中位数分别173．98μg/L和176．30μg／L，均大于100μG/L。城市儿童低体重检出率为2．00％，发育迟缓和消瘦检出率均为0．00％；农村儿童低体重、发育迟缓和消瘦的检出率分别为6．25％、6．25％和14．58％。甘肃武威0～3岁儿童低体重和消瘦检出率均低于国家水平。结论：甘肃省武威3岁以下儿童人群碘营养及生长发育状况良好。

英文摘要：

Objective： To evaluate iodine nutrition and growth and development of children under three years old in Wuwei city of Gansu province, provide a scientific basis for further adjusting salt iodization concentration and directing iodine supplementation reasonably in infants. Methods： A total of 98 children under three years old were randomly selected from Gansu province, random urine specimens were obtained for successive two times within one month; the urine iodine concentration was detected; ;body height and body weight were measured; Z score was calculated to evaluate growth and development of the children. Results： The medians of urine iodine in random urine specimens for successive two times within one month were 173.98 μg/L and 176. 30 μg/L, respectively, which both were higher than 100 μg,/L; the detection rates of low body weight, developmental retardation, and emaciation were 2.00%, 0.00%, 0. 00% in urban children and 6. 25%, 6. 25%, 14. 58% in rural children; the detection rates of low body weight and emaciation in 0 - 3 - year - old children in Wu- wei city of Gansu province were lower than national levels. Conclusion： Iodine nutrition, growth and development of children under three years old in Wuwei city of Gansu province are good.
