摘要
目的了解麻城市居民食用碘盐质量状况,为制定防治策略提供科学依据。方法根据《全国碘缺乏病监测方案》随机采取居民户盐样,2012—2014年共采集盐样900份,实验室依据《GB/T 13025.7-1999》直接滴定法进行定量检测。对居民饮用水水碘进行普查。结果 2012—2014年共检测麻城市居民户食用碘盐样品900份,其中非碘盐6份,不合格碘盐37份,碘盐覆盖率、碘盐合格率、合格碘盐食用率为99.33%、95.86%、95.22%。市场销售碘盐执行新的标准后,2014年盐碘中位数为24.19 mg/kg,3年中2014年度合格碘盐食用率相对较低（χ2=12.64,P〈0.05）,无碘盐在个别乡镇检出。居民饮用水水中碘含量为0.1~69.71μg/L。结论麻城市居民碘盐覆盖率、合格碘盐食用率、碘盐合格率继续保持在消除碘缺乏病标准,建议应加强居民碘营养监测,对重点人群开展个性化的碘营养指导。
[Objective]To explore the quantity of iodized salt consumed by the residents in Macheng City, and provide scientific evidence for developing control strategies. [Methods]A total of 900 iodized salt samples were collected from households from 2012-2014, according to ＂National Iodine Deficiency Disorders Monitoring Program＂. The content was determined by direct titrimetrie method according to ＂GB/T13025.7-1999＂. Drinking water iodine census was performed.[Results]Of 900 samples, 6 were non-iodized salt, 37 were unqualified iodized salt. The covering rate, qualified rate, edible rate of iodized salt was 99.33%, 95.86% and 95.22%, respectively. The median of salt iodine was 24.19 mg/kg after implementing new standard of iodized salt in 2014, and the edible rate of qualified iodized salt in 2014 was lower than 2012 and 2013 （X2=12.64,P〈0.05）, non-iodized salt was checked out only in some villages and towns. The iodine content of water drinking was 0.1-69.71μg/L. [Conclusion]The covering rate, qualified rate, edible rate of iodized salt keeps staying within the standards of elimination of IDD in Macheng City, It is advised to strengthen monitoring of iodine nutrition, and to carry out personalized iodine nutrition guidance among key population.
