摘　　要：[目的]分析食盐加碘量调整对学龄儿童碘营养水平的影响.[方法]对食盐加碘量为20～60 mg/kg的1995年、1997年、1999年和食盐加碘量为（35±15）mg/kg的2002年、2005年山东省碘缺乏病监测中儿童碘营养状况进行分析.[结果]食盐加碘量调整前后分别检测尿样1 051份、720份,尿碘中位数分别为269.4 μg/L、213.9 μg/L,推算的每人每天碘摄入量分别为404.1 μg、320.8 μg,尿碘＜100 μg/L者所占比例分别为14.94%、11.53%,尿碘≥300 μg/L者所占比例分别为46.52%、27.22%（P＜0.01）.盐加碘量调整前后分别调查8～10 岁儿童3 668人、2 400人,甲状腺肿大率（触诊法）分别为14.53%、5.08%（P＜0.01）.[结论]调整食盐加碘量后儿童碘营养状况良好,儿童甲状腺肿大率明显下降.　[Objective]To analyze the impact of the iodine nutrition on children after adjusting the iodine content in iodine salt.[Methods]The status of iodine nutrition under the level of iodine in salt of 20-60mg/kg in 1995,1997,1999 and（35±15）mg/kg in 2002,2005 were analyzed.[Results]1 051 and 120 urine samples were tested before and after iodine adjustment,the medians of the children＇s urine iodine were 269.4 μg/L and 213.9 μg/L respectively The iodine intakes were 404.1 μg/d·p and 320.8 μg/d·p.The ratios of the children＇s urine iodine which less than 100 μg/L accounted for 14.94% and 11.53%.The ratios of the children＇s urine iodine which more than 300 μg/L accounted for 46.52% and 27.22%.The total goiter rate of the children measured with palpation was 14.53%（3 668） and 5.08%（2 400） respectively.[Conclusion]The results indicated that the children＇s iodine nutrition state after adjusting the iodine content in iodine salt was good and the total goiter rate of the children was obviously decreased.
