摘　　要：目的了解河北省吴桥县8～10岁儿童碘营养状况。方法对吴桥县1209名8～10岁儿童进行甲状腺触诊,对584名儿童采集尿样,尿碘的测定采用过硫酸铵消化-砷铈催化分光光度测定,采集250份居民户食用盐样,食用盐中碘含量的测定采用直接滴定法。结果共发现74例甲状腺肿大者,肿大率为6.1%。尿碘中位数为208.36μg/L,每人每天碘摄入量为312.54μg/d。尿样中尿碘<50μg/L的样本占总检测数的4.6%,尿碘<100μg/L的样本占总检测数的18.5%,尿碘在200～299μg/L的样本占总检测数的27.2%,尿碘≥300μg/L的样本占总检测数的26.5%。盐碘中位数为26.96mg/kg,碘盐覆盖率为77%、碘盐合格率为94%、合格碘盐食用率为72%。结论吴桥县的甲状腺肿属于地方性的,该县儿童尿碘水平超过了适宜范围,存在碘营养过剩。Objective To assess the nutritional status of iodine in school children of Wuqiao County in Hebei Province. Methods 1209 school children aged 8 - 12 years were selected by multistage random sampling. Thyroid size estimated by inspection and palpation was graded according to the criteria recommended by WHO. The concentration of urinary iodine and iodine in salt was also measured. Results There were 74 goiter cases, accounted for 6. 1% of total students investigated. The median of urinary iodine was 208μg /L and the median of iodine intake was 312 μg /d. The excretion of urinary iodine at 100μg /L, 50μg /L,200 - 300μg /L and 300μg /L accounted for 18. 5% ,4. 6% ,27. 2% and 26. 5% of total detected samples respectively. The coverage of iodized salt in the area was 77% and the iodine in iodized salt was at a median of 26. 96mg /kg. Conclusion Goiter is endemic in Wuqiao County of Hebei Provinee. Urinary iodine of school children was more than the optimal range,and the iodine nutrition was excessive in this area.
