2014-2015年大连市盐碘监测结果分析

Analysis of Iodine Content in Table Salt in Dalian From 2014 to 2015

目的了解大连市2014-2015年居民食用碘情况,为进一步巩固碘缺乏病防治成果提供依据。方法 2014-2015年在大连市10个县区市抽取居民食盐样品,利用直接滴定法测定盐中碘含量,计算碘盐的覆盖率、合格率、合格碘盐食用率和非碘盐率。结果 2014抽取居民食盐样品3 010份,合格2 931份,合格碘盐食用率为97.38%,非碘盐15份,非碘盐率为0.50%;2015年抽取居民食盐样品3 000份,合格2 923份,合格碘盐食用率为97.43%,非碘盐45份,非碘盐率为1.50%。结论 2015年较2014年非碘盐率有上升趋势,应加大对重点地区和群众的食用碘盐相关知识的宣传力度,确保居民科学补碘,预防碘缺乏病的发生。

Objective To analyze the status of iodine content in table salt available in Dalian from 2014 to 2015 and provide scientific basis for further prevention of IDD. Methods Table salt samples were collected from households in ten counties of Dalian using stratified cluster random sampling method and iodine content in the samples were measured according to GB / T 13025. 7-2012. Also,the coverage rate,qualified rate,non-iodized salt rate and edible rate of qualified iodized salt were calculated. Results Among 3010 salt samples obtained in 2014,2931 were qualified and the edible rate of qualified iodized salt was 97. 38%. Fifteen samples were non-iodized and the rate was 0. 50%. Among 3000 salt samples obtained in 2015,2923 were qualified and the edible rate of qualified iodized salt was 97. 43%. Fourty five samples were non-iodized and the rate was 1. 50%. Conclusion The trend in the non-iodized salt rate in Dalian was rising comparing 2015 and 2014.The related knowledge of edible iodized salt was widely promoted to ensure scientific iodine supplement and prevent IDD.
