2014年四川省碘盐监测结果分析

摘要

目的掌握2014年四川省居民碘盐含量情况及存在问题，为适时采取针对性措施，保障大众健康，为进一步推动持续消除碘缺乏病工作提供科学依据。方法根据国家碘盐监测方案抽取四川省21市185县，每县随机抽取居民户盐样300份，用《制盐工业通用试验方法碘离子的测定》（GB/T13025.7-2012）中仲裁法进行定量检测，应用SPSS19.0统计软件进行数据分析。结果2014年四川省应监测食盐55500份，实际监测食盐55505份，其中合格碘盐54322份，不合格碘盐991份，非碘盐192份，合格碘盐食用率为97.58%，碘盐覆盖率为99.72%，碘盐合格率为97.85%，加碘盐中位数为28.85 mg/kg，加碘盐均值为29.11 mg/kg，标准差为5.63 mg/kg，变异系数为19.34%，食用盐碘中位数为28.80 mg/kg。结论2014年四川省居民户碘盐覆盖率大于或等于95.00%，合格碘盐食用率超过90.00%，达到国家消除碘缺乏病标准，但非碘盐问题依然存在，不合格碘盐以低浓度为主，需继续加强碘盐市场监管，强化居民健康行为干预。%Objective To master the status of iodized salt content in residents of Sichuan Province during 2014 and ex-isting problems in order to provide scientific basis for timely taking the pertinent measures ,protecting the health of the general public and further promoting the sustainable elimination work of iodine deficiency disorders. Methods According to the national iodized salt monitoring programs,totally 185 counties in 21 cities of Sichuan province were sampled and 300 salt samples were randomly extracted from residents in each county. The iodine concentration in salt was quantitatively detected by the arbitration method in the Determination of Iodine Ion of the Salt Industry General Test Method (GB/T13025.7-2012). The SPSS19.0 statistical software was used to analyze the data. Results 55 500 salt samples should be monitored in Sichuan Province and actually 55 505 samples were monitored,in which 54 322 samples were qualified iodized salt,991 samples were unqualified iodized salt and 192 samples were non-iodized salt. The edible rate of qualified iodized salt was 97.58%,the coverage rate of iodized salt was 99.72%and the qualified rate of iodized salt was 97.85%. The iodized salt median was 28.85 mg/kg. The iodized salt mean was 29.11 mg/kg , with a standard deviation of 5.63 mg/kg. The coefficient of variation was 19.34%and iodine median of edible salt was 28.80 g/kg. Conclusion The coverage rate of iodized salt among residents in Sichuan Province during 2014 was more than or equal to 95%and the edible rate of qualified iodized salt was more than 90%,reaching the national standard for eliminating iodine deficiency disorders. But non-iodized salt problems still exist. Unqualified iodized salt was mainly low concentration ,which needs to continue to strengthen the market supervision and the intervention to health behavior of residents.
