2002年广东省居民户碘盐监测及其质量分析

Analysis on household iodized salt in Guangdong province in 2002

目的为了解广东省居民食用碘盐及其质量状况。方法按卫生部下发的《关于全国第四次碘缺乏病监测方案的实施意见》要求进行监测。结果盐碘中位数为33.4mg/kg,居民户合格碘盐食用率为88.6%,碘盐覆盖率为92.4%。合格碘盐食用率达90%以上的有16个市,占76.2%,不同盐种碘盐合格率存在非常显著性差异(P<0.001),加碘精制盐的合格率明显高于日晒细盐和粗海盐,重病区和中病区的碘盐合格率明显高于轻病区和非病区。结论广东省2000年实现消除碘缺乏病阶段目标后,全省碘盐供应及质量基本稳定,但在珠江三角洲及沿海地区仍然存在不少非碘盐冲销市场现象,个别地区盐碘浓度有偏高趋势。
