目的掌握四川省2012~2013年居民碘盐情况,为碘缺乏病防治提供科学依据。方法根据国家碘盐监测方案,每个县随机抽取居民户盐样,用《制盐工业通用试验方法碘离子的测定》GB/T13025.7-1999中仲裁法进行定量检测,采用SPSS19.0进行统计分析。结果 2012年四川省居民户合格碘盐食用率97.53%、碘盐覆盖率99.66%、碘盐合格率97.86%、加碘盐中位数30.50 mg/kg;2013年四川省居民户合格碘盐食用率98.02%、碘盐覆盖率99.71%、碘盐合格率98.31%、加碘盐中位数29.00 mg/kg;2013年3个指标较2012年有所提高(P<0.05)。结论两年的合格碘盐食用率、碘盐覆盖率和碘盐合格率3项指标都大于90%,碘盐浓度有所下降,碘盐质量需进一步提高。
Objective To understand the iodized salt of residents in Sichuan province from 2012 to 2013, and to provide a scientific basis for the prevention and treatment of iodine deficiency disorders. Methods According to the national iodized salt monitoring program, salt samples of households were randomly selected from each county and quantitatively detected by the arbitration method of “Determination of iodide in general test methods for salt industry” GB / T13025.7-1999, and SPSS19.0 Statistical Analysis. Results In 2012, the consumption rate of qualified iodized salt of households in Sichuan Province was 97.53%, the coverage of iodized salt was 99.66%, the pass rate of iodized salt was 97.86%, and the median of iodized salt was 30.50 mg / kg. In 2013, The rate of iodized salt was 98.02%, the coverage rate of iodized salt was 99.71%, the pass rate of iodized salt was 98.31% and the median of iodized salt was 29.00 mg / kg. The three indexes in 2013 were higher than those in 2012 (P <0.05). Conclusion Three indicators of qualified iodized salt consumption, iodized salt coverage and qualified rate of iodized salt in two years all exceeded 90%, the iodized salt concentration decreased and the quality of iodized salt needed to be further improved.
