Analysis of the Children's Iodine Nutrition State after Adjusting the Iodine Content of Iodine Salt in Shandong

[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.
