2005年河北省碘缺乏病监测结果分析

Analytical study on IDD surveillance in Hebei Province in the year of 2005

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。

Objectives To learn about the current situation of IDD and iodine status of the whole population in Hebei Province in 2005. To assess the effectiveness of salt iodization on the control of IDD. Methods Population sample was selected by Proportionate to Population Size Sampling （ PPS）. Results The iodine content of 1 200 edible salt samples collected randomly from households was measured, with iodine median being 28.6 mg/kg, qualification rate of iodized salt at household level being 79.4%. The goiter status of 1 200 children aged 8 to 10 years old were examined by both palpation and B - type of ultrasonic, prevalence of goiter being 2.75% and 2.17% respectively. The iodine content of 362 spot urinary specimen randomly collected from the above children 1 200 was tested, with iodine median being 212.35 μg/L. The mean IQ of i 200 children aged 8 to 10 years old was 105.3. Conclusions IDD is under effective control in Hebei Province. Due to the spread of non - iodized salt, the qualification rate of iodized salt at household level was relatively low compared with national standard. The iodine nutrition of children aged 8 to 10 years old was good in general.
