目的了解和分析吉林省各市售食盐碘含量变化状况并为碘缺乏病防治依供依据。方法于2008、2012年在吉林省全部9个市抽取居民食盐样品,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,并对2年各市食盐中碘含量进行比较。结果 2008年抽取居民食盐样品17 400份,合格17 284份,合格碘盐食用率为99.33%,非碘盐10份,非碘盐率为0.05%;2012年抽取居民食盐样品17 783份,合格17 612份,合格碘盐食用率为99.07%,非碘盐5份,非碘盐率为0.03%;各城市2012年食盐碘含量普遍低于2008年(P<0.05)。结论吉林省2008年和2012年合格碘盐食用率均符合国家标准,可通过加强碘盐的管理和监测保证合格碘盐的供应。
Objective To understand and analyze the changes of iodine content in all kinds of salt in Jilin Province and to provide basis for the prevention and treatment of iodine deficiency disorders. Methods Salt samples were collected from all 9 cities of Jilin Province in 2008 and 2012, the iodine content in salt was calculated, the coverage rate of iodized salt, pass rate, qualified iodized salt rate and non-iodized salt rate were calculated. Salt iodine content comparison. Results In 2008, 17 400 salt samples of residents were qualified and 17 284 were qualified. The qualified iodized salt consumption rate was 99.33%, non-iodized salt was 10, and non-iodized salt rate was 0.05%. In 2012, 17 783 samples of salt were collected and qualified 17 612, the qualified iodine salt consumption rate was 99.07%, non-iodized salt 5, non-iodized salt rate was 0.03%; 2012 urban salt iodine content is generally lower than in 2008 (P <0.05). Conclusion The iodine salt consumption rates in Jilin Province in 2008 and 2012 all meet the national standards, and the supply of qualified iodized salt can be guaranteed by strengthening the management and monitoring of iodized salt.
