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30.2mg/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、196.8μg/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238.1μg/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(30 mg/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。
Objective To understand the iodine nutrition of infants and young children in rural Panshi, Jilin Province, and to provide evidence for the prevention and treatment of iodine deficiency disorders. Methods In April 2009, three townships, Baoshan, Mingcheng and Chidao Mountain, in Panshi City, Jilin Province, were selected as the investigation points. Lactating women, 0 ~ 2 years old infants (lactating women Of children) each 50 people. In a month to collect three consecutive lactating women, 0 to 2-year-old infants and young children at random urine samples were collected in a household salt water samples, drinking water samples. Determination of iodine by direct titration and arsenic and cerium catalytic spectrophotometry for determination of iodine in urine, water and milk. Results The median of iodine in residents was 30.2mg / kg, milk iodine 192.8μg / L and water iodine 2.8μg / L respectively. The median urinary iodine of lactating women and children aged 0 ~ 2 years were 224.9μg / L and 209.0 μg / L. Urinary iodine and milk iodine in lactating women ranged from 0 to 6 months, from 7 to 12 months and from 13 to 24 months to 207.6 μg / L, 212.6 μg / L, 235.5 μg / L, 147.5 μg / L and 249.0 μg / L, 196.8μg / L urine iodine increased with the extension of lactation time, milk iodine was the opposite; infant urinary iodine 0 ~ 6 months, 7 ~ 12 months, 13 ~ 24 months were 238.1μg / L , 248.0μg / L, 158.2μg / L, urinary iodine decreased with the increase of age. Conclusion The present iodized salt concentration (about 30 mg / kg) is suitable for lactating women and infants in Panshi area of our province. Infants and young children in the late breastfeeding, timely dietary supplements to increase iodine-rich foods to prevent iodine malnutrition in infants and young children.
