摘　　要：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 determine and analyze the status of iodine content in table salt available from markets in Jilin province, and to provide bases for prevention and treatment of iodine deficiency disorders. Methods Table salt samples were collected from households in nine cities of Jilin province using stratified cluster random sampling method and iodine content in the samples were measured according to GB/T 13025.7 - 1999 ; and the coverage rate, qualified rate, non-iodized salt rate, and edible rate of qualified iodized salt were calculdted. In addition, the iodine content of the salt was compared and analyzed between the two years. Results Among 17 400 salt samples obtained in 2008,17 284 were qualified and the edible rate of qualified iodized salt was 99. 3%. Ten samples were non-iodized and the non-iodized salt rate was 0. 05%. Among 17 783 salt samples obtained in 2012,17 612 were qualified and the edible rate of the quali- fied iodized salt was 99. 07%. Five samples were non-iodized and the rate of non-iodized salt was 0. 03 %. Iodine content of table salt in 2012 was lower than that in 2008, with a statistically significant difference（ P 〈 0.05 ）. Conclusion The edible rate of the qualified iodized salt in Jilin province met the national standards in 2008 and 2012. Strengthening man- agement and monitoring can guarantee the supply of qualified iodized salt.
