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。
Objective: To evaluate the status of iodine nutrition and growth in children under 3 years old in Wuwei, Gansu Province, and provide scientific basis for further adjustment of iodized salt and rational guidance of iodine supplementation in infants and young children. Methods: 98 children from 0 to 3 years old were randomly selected in Gansu Province. Two random urine samples were collected within 1 month. The urine iodine content was measured. The height and weight were measured. The Z score was calculated to evaluate the growth and development of children. Results: The urinary iodine median of two consecutive random urine samples for one month were 173.98μg / L and 176.30μg / L respectively, both of which were higher than 100μg / L. The detection rate of low weight of urban children was 2.00%, and the detection rate of stunting and weight loss was 0.00%. The detection rates of low birth weight, stunting and weight loss in rural children were 6.25%, 6.25% and 14.58% respectively. The detection rates of low weight and weight loss of children aged 0-3 years in Wuwei, Gansu Province were lower than the national level. Conclusion: The iodine nutrition and growth and development of children under 3 years of age in Wuwei, Gansu Province are good.
