目的掌握河北省2005年碘缺乏病病情和人群碘营养状况,评价食盐加碘控制碘缺乏病的效果。方法采用人口比例概率抽样方法(PPS)进行抽样。结果采集测定居民户盐样1 200份,盐碘中位数为28.6 mg/kg,碘盐合格率为90.2%。触诊法和B超法检查8～10岁儿童1 200名,肿大率分别为2.75%和2.17%。采集测定8～10岁儿童1次即时尿样362份,尿碘中位数为212.35μg/L。测试8～10岁儿童1 200名智商,平均智商为105.3。结论河北省碘缺乏病得到有效控制,但由于受非碘盐的影响,居民碘盐合格率较低;8～10岁儿童的碘营养状况总体上良好。
Objective To master the status of iodine deficiency disorders and iodine nutrition in Hebei Province in 2005 and evaluate the effect of salt iodization on iodine deficiency disorders. Methods Sampling was conducted using the Population Probability Sampling (PPS) method. Results A total of 1 200 salt samples were collected from residents. The median salt iodine concentration was 28.6 mg / kg. The pass rate of iodized salt was 90.2%. Palpation and B-ultrasonography were used to examine 1 200 children aged 8-10 years. The rate of swelling was 2.75% and 2.17% respectively. A total of 362 urine samples were collected from 8 to 10-year-old children and the urinary iodine median was 212.35μg / L. 1,200 children aged 8 to 10 were tested with an average IQ of 105.3. Conclusion The iodine deficiency disorders in Hebei Province are effectively controlled. However, due to the impact of non-iodized salt, the qualified rate of iodized salt is lower. The iodine nutrition status of children aged 8-10 is generally good.
