摘要
目的了解和评价河北省易县学龄儿童碘营养状况，为制订碘缺乏病防治措施提供科学依据。方法采用资料收集方法，对1998～2011年河北省学龄儿童尿碘监测结果进行回顾性分析。1998—2011年在易县按东、西、南、北、中5个方位各抽取1个乡镇，每个乡镇抽取1所小学，每所小学抽取8—10岁儿童尿样20人份进行尿碘测定。尿碘测定采用砷铈催化分光光度法。尿碘判定标准依据《碘缺乏病消除标准》（GB16006—2008）和《碘缺乏病及其消除指南》。结果1998—2011年共采集8～10岁儿童尿样1725份，尿碘中位数为243．26μg／L。各年度8～10岁儿童尿碘中位数均在100μg／L以上，尿碘在100μg／L以下的比率〈50％，50μg／L以下的比率〈20％。总体尿碘峰值保持在200μg／L附近，呈向右拖尾的正偏态分布。不同年龄、性别、民族学龄儿童尿碘水平比较，差异无统计学意义（P〉0．05）。结论易县学龄儿童碘摄入量近年来可满足机体需要，碘营养状况处在较适宜水平。
Objective To investigate and evaluate the iodine nutritional status of school-age children in Yi county of Heibei Province, and to provide scientific basis for the development of control measures to iodine deficiency disorders. Methods Retrospectinely analyzed school-age children urinary iodine monitoring results of Yi County of Hebei Province from 1998 to 2011. One township was selected randomly in each of the five directions （east, west, south, north and center） from 1998 to 2011. One elementary school was randomly chosen in each of the five townships. And at least 20 urine samples of 8 - 10 years old children were randomly collected in each school selected. Urinary iodine contents were determined through arsenic cerium catalytic spectrophotometric method. Urinary iodine determination standard according to ＂The Standard of Iodine Deficiency Disorders Elinination＂ （GB 16006-2008） and ＂The Iodine Deficiency Disorders Elinination Guide＂. Results A total of 1725 children urinary samples were collected from 1998 to 2011, urinary median was 243.26 μg/L, each of the median urinary iodine was higher than 100 μg/L. The ratio of urinary iodine less than 100 μg/L was 〈 50% over the years, and less than 50 μg/L was 〈 20%. Overall, the highest value of urinary iodine stayed at approximately 200 μg/L, showing positively skewed distribution that was skewed to the right. Urinary iodine level was compared among different ages, gender and ethnicity, and the difference was not statistically significant（P 〉 0.05）. Conclusions In recent years, the iodine intake of school-age children of Yi County can meet the body needs, and the iodine nutrition is at an appropriate level.
