全民食盐加碘后碘缺乏地区儿童碘营养状况分析

目的:了解全民食盐加碘后8~10岁儿童碘营养状况,为今后碘缺乏病防治提供科学依据。方法:采用按人口比例概率抽样方法(PPS)抽样检测盐碘、儿童尿碘以及甲状腺肿大情况。结果:实施全民食盐加碘10年后,山东省碘盐覆盖率为97.2%,碘盐合格率为97.1%,合格碘盐食用率为94.3%;尿碘中位数为227.7μg/L,未见≤20μg/L的样本,>100μg/L的样本数为89.7%;甲状腺肿大率由1995年的22.3%降至2005年的4.4%。结论:实施全民食盐加碘10年,山东省人群碘营养状况得到显著改善,处于较适宜碘营养状态,山东省进入可持续消除碘缺乏病阶段。

Analysis of iodine nutrition after universal salt iodization among children aged 8～10 years in iodine deficiency area

Objective：To investigate the status of iodine nutrition in 8-10years c,hildren after a ten - year universal salt iodization （USI） in the iodine difeeiency area. Methods： According to＂National Iodine Difeciency Disease Surveillance Project＂ and Probability Proportion to Size method （pps）, goiter was detected by palpation and ultrasound, urine iodine salt iodine were measured. Results： After implementing USI, The rate of qualified iodized salt was elevated to 94.3% ; the goiter rate of 8 -- 10 years children was decreased to 4. 4 % ;the level of urine iodine was 227.7μg/L. Conclusions： After 10 - year USI, the status of iodine nutrition in Shandong province has been promoted obviously. Shandong Province has commenced to a continua[ stage to eliminate the IDD.
