目的及时掌握自贡市自流井区居民户碘盐普及情况,评价碘盐措施落实情况,为适时采取针对性防治措施和科学调整干预策略提供依据。方法根据《四川省自贡市2009-2015年碘盐监测方案》进行监测,实验方法按照GB/T13025.7-2012中仲裁法(氧化还原法)定量测定盐中碘含量。结果 2009-2015年碘含量平均值和碘含量中位数基本稳定在32.0 mg/kg左右;而碘盐合格率和合格碘盐食用率基本呈逐年上升趋势;碘盐覆盖率也达到全覆盖。2015年的监测碘盐中位数为29.17 mg/kg,盐碘覆盖率99.33%,合格碘盐285份,合格碘盐食用率95.00%。结论自贡市自流井区的居民户碘盐覆盖率、合格率、合格碘盐食用率均符合国家消除碘缺乏病标准,但非碘盐每年均有检出,还需加强监测和居民的健康教育;自贡是食用盐生产基地,生产的碘盐和复合营养强化盐品种繁多,应加强打击私盐,持续有效地供给合格碘盐,确保碘缺乏病的消除。
Objective To grasp the popularization of iodized salt of residents in Ziliujing District in Zigong City in time and evaluate the implementation of iodized salt measures in order to provide the basis for timely and targeted prevention and treatment measures and scientific adjustment of intervention strategies. Methods According to “2009-2015 iodine salt monitoring scheme in Zigong City of Sichuan Province”, the method was used to quantitatively determine the iodine content in salt according to the arbitration method (redox method) in GB / T13025.7-2012. Results The median of iodine content and iodine content in 2009-2015 basically remained stable at about 32.0 mg / kg. However, the pass rate of iodized salt and the qualified iodized salt basically showed an upward trend year by year. The coverage of iodized salt also reached the full coverage. The median iodine salt monitoring in 2015 was 29.17 mg / kg, salt iodine coverage was 99.33%, qualified iodized salt was 285, and qualified iodized salt was 95.00%. Conclusion The iodized salt coverage rate, pass rate and qualified iodized salt rate of residents in Ziliujing District of Zigong City all meet the national standard of eliminating iodine deficiency disorders. However, non - iodized salt is detected every year, and monitoring and residents’ health education should be strengthened. Zigong is the production base of edible salt. Due to its wide variety of iodized salt and compound nutritional fortified salt, it is necessary to crack down on private salt and continue to effectively supply qualified iodized salt so as to ensure the elimination of iodine deficiency.
