目的掌握浙江省2011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。方法运用人口比例概率抽样方法抽取30个调查点,采用8～10岁儿童甲状腺肿大率、尿碘、盐碘和外环境水碘4大指标进行评价。结果B超法检查8～10岁儿童1236名,肿大率为4.13%;采集测定儿童、孕妇、哺乳期妇女即时尿样分别391、456、457份,尿碘中位数分别为237.09、159.60和45.23μg/L;采集测定盐样1236份,碘盐中位数为28.00 mg/kg,碘盐覆盖率为95.06%;碘盐合格率为96.60%,居民合格碘盐食用率为91.83%;采集测定水样37份,水碘中位数3.94μg/L。结论浙江省采取的以食盐加碘为主导的综合性防治措施效果显著,人群碘营养水平总体适宜、平稳。
Objective To understand the status of iodine deficiency disorders and iodine nutrition status in Zhejiang province in 2011 and evaluate the effect of salt iodization on iodine deficiency disorders. Methods Thirty sampling points were selected by probabilistic population sampling method. Goat enlargement rate, urinary iodine, salt iodine and external water iodine 4 indexes of 8 ~ 10 years old children were evaluated. Results A total of 1236 children aged 8-10 years were examined by B-mode ultrasonography. The rate of enlargement was 4.13%. The real-time urine samples collected from children, pregnant women and lactating women were 391,456,457 and the median urinary iodine were 237.09 and 159.60 And 45.23μg / L respectively. The 1236 salt samples were collected, the median of iodized salt was 28.00 mg / kg, the coverage of iodized salt was 95.06%, the qualified rate of iodized salt was 96.60%, and the percentage of resident iodine salt was 91.83% 37 water samples were collected and the median water iodine concentration was 3.94 μg / L. Conclusion The comprehensive prevention and treatment measures dominated by salt iodization in Zhejiang Province are significant. The iodine nutrition level of the population is generally suitable and stable.
