内蒙古城镇和农牧区、病区和非病区碘盐及碘缺乏病病情分析

Analysis for iodized salt and IDD situation in town,farm and pastoral areas,IDD areas and no IDD areas in Inner Mongolia

目的了解内蒙古城镇、农牧区、病区、非病区碘盐和碘缺乏病现状。方法对１９９７年全区碘缺乏病中期评估资料进行分析。结果精制盐的碘化效果较粉碎盐好，但在内蒙古由于生活习惯，有５０％以上居民食用粉碎盐。城镇碘盐合格率高于农牧区，但因为多数城镇为历史非病区，碘盐普及时间短，故儿童甲肿率仍偏高。结论经过多年防治，病区儿童甲肿率已下降到５％以下，可粗制碘盐的质量尚有待提高。非病区碘盐合格率达到了９０％以上。

Objective To evaluate iodized salt and IDD situation in town,farm and pastoral areas,IDD areas and no IDD areas in Inner Mongolia.Methods The data from middle period evaluation of Inner Mongolia in 1997 were analyzed.Results Iodized effect of refined salt was better than that of crude salt,but there were 50% residents cooking with crude salt because of habit.The qualified iodized salt rate in town was higher than that in farm and pastoral areas,but most of the towns were no IDD areas in history.Children's goiter rate was still higher with a shorter time supply of iodized salt in the towns.Conclusions Prevalence of goiter in IDD areas has already decreased to below 5% through prevention for many years,but the quality of crude salt in these areas should be improved.The qualified iodized salt rate in no IDD areas is above 90% now,but it is important for these areas to establish sustainable guarantee system.
