目的了解2012年黔东南州居民食盐碘含量水平、碘盐覆盖率、合格碘盐食用率,为推动碘缺乏病防治工作持续开展提供依据。方法按照《贵州省碘缺乏病监测方案》对黔东南州16县(市)随机抽取320个监测点,每个监测点随机抽检15户居民食用盐≥50 g,采用GB/T13025.7-1999进行检测。结果 2012年共检测4 800份食盐,盐碘均数为30.13mg/kg,碘盐覆盖率为99.90%,合格碘盐食用率为97.65%,非碘盐率为0.10%。结论黔东南州16县(市)的碘盐覆盖率及合格碘盐食用率继续保持在《碘缺乏病消除标准》达标范围内,碘盐质量总体良好;存在盐碘变异系数波动范围较大的原因是市场上仍可以销售老标准生产的碘盐。
Objective To understand the level of iodine in salt, the coverage of iodized salt and the rate of qualified iodized salt in the residents of Qiandongnan Prefecture in 2012 to provide the basis for continuing the prevention and treatment of iodine deficiency disorders. Methods A total of 320 monitoring sites were randomly selected from 16 prefectures and cities of Qiandongnan Prefecture in accordance with the “Monitoring Scheme of Iodine Deficiency Disorders in Guizhou Province”. Fifteen households were randomly sampled for salt consumption ≥50 g at each monitoring site. GB / T13025.7-1999 Test. Results A total of 4 800 salt samples were detected in 2012, with average salt iodine concentration of 30.13 mg / kg, iodine salt coverage of 99.90%, qualified iodine salt consumption rate of 97.65% and non-iodized salt rate of 0.10%. Conclusion The coverage of iodized salt and the rate of qualified iodized salt in 16 counties (prefectures) in Qiandongnan continued to be within the standard of “elimination standard of iodine deficiency disorders”, and the quality of iodized salt was generally good. There was a wide fluctuation range of salt iodine coefficient of variation The reason is that the market can still sell the iodized salt produced by the old standard.
