吉林省磐石市农村婴幼儿碘营养水平调查

目的了解吉林省磐石市农村婴幼儿的碘营养水平，为制订碘缺乏病的防治策略提供依据。方法于2009年4月，选择吉林省磐石市宝山、明城、烟筒山3个乡为调查点，从3个乡的卫生院登记中抽取哺乳期妇女、0-2岁婴幼儿（哺乳期妇女的孩子）各50人。在1个月内连续3次收集哺乳期妇女、0-2岁婴幼儿的随意一次尿样，采集1次居民家中食用盐盐样、饮用水水样。采用直接滴定法测盐碘，砷铈催化分光光度法测定尿、水、乳汁含碘量。结果居民户盐碘中位数为30．2rag／kg、乳碘192．8μg／L、水碘2．8μg／L，哺乳妇女、0～2岁婴幼儿尿碘中位数分别为224．9μg/L、209．0μg/L。哺乳妇女的尿碘和乳碘0～6个月、7～12个月、13～24个月分别为207．0μg／L、212．6μg／L、235．5μg／L，147．5μg/L、249．0μg／L、196．8肛g／L尿碘随着哺乳时间的延长而增加，乳碘却相反；婴幼儿的尿碘0～6个月、7—12个月、13～24个月分别为238．1斗g／L、248．0μg／L、158．2μg／L，尿碘随着月龄的增加而减少。结论当前碘盐浓度（30mg／kg左右）对我省磐石地区哺乳期妇女、婴幼儿来说是适宜的。婴幼儿在母乳喂养的后期，要及时补充膳食营养，增加含碘丰富的食物，防止婴幼儿碘营养不良的发生。

A survey on the iodine status of infants in rural areas of Panshi city,Jilin province

Objective To understand the iodine nutrition level of infants in rural areas of Panshi city of Jilin provine, in order to provide scientific basis for the sustainable elimination of Iodine Deficiency Disorders（ IDD）. Methods To select three townships, Baoshan, Yantongshan and Mingcheng in Panshi city, Jilin Province, 2009. 50 Infants aged 0 to 2 and 50 lactating women were selected from the registered books of hospitals in three townships. 3 continuouslly casual urine samples of lactation and infant, drinking water samples and breast milk iodine of lactating women, and their iodine levels were determined by As - Ce catalysis spectrophotometry method. The table salt at household was also collected and the iodine level was determined by direct titration method. Results The median of salt iodine, drinking water, breast miek eneentratin were 30.2 mg/kg, 2.8 μg/L, 192 μg,/L, respectively, the urinary median iodine of lactation and infants were 224.9 μg/L, 209.0 μg/L, respectively. The median of urina- ry iodine and breast milk concentration of lactating women at 0 to 6 months, 7 to 12 months, 13 to 24 months were 207.0 μg/L, 212.6μg/L, 235.5 μg/L and 147.5 μg/L, 249.0μg/L, 196.8μg/L, respectively. The urinary median iodine of lactating women was increased with the increase of lactating time , on the contrary, that of breast milk concentration was reduced with the increase of lactating time. The urinary median iodine of infants aged 0 to 2 at 0 to 6 months, 7 to 12 months, 13 to 24 months were 238μg/L, 248.0 μg/L, 158.2 μg/L, respectively, and it was reduced with the increase of monthages. Conclusions The current salt iodine content was suitable for lactating women and infants. In order to prevent the occurrence of malnutrition of iodine, in later period of mother＇ s milk feed, infants should be supplied meals timely, increasiug foods containing protein and iodine.
