2017~2019年天津市某区碘盐监测

Monitoring on iodized salt in a district of Tianjin city,2017-2019

目的了解2017~2019年天津市某区居民户食用盐情况,为科学防治碘缺乏病提供依据。方法依据《天津市碘缺乏病监测方案》规定的抽样方法,每年抽取15个街镇的60个居委会(行政村),随机采集居民户食用盐样900份。采用GB/T 13025.7-2012直接滴定法进行定量检测。结果 2017~2019年共检测居民户食用盐2 700份,盐碘含量中位数为25.90 mg/kg。其中合格碘盐2 236份,非碘盐260份,不合格碘盐204份,碘盐合格率、碘盐覆盖率、合格碘盐食用率分别为91.64%、90.37%和82.81%。2019年碘盐合格率、碘盐覆盖率、合格碘盐食用率较之前有明显提高(P<0.01),分别为94.84%、94.78%和89.89%。结论 2017~2019年天津市某区居民户碘盐监测相关技术指标呈逐年上升趋势,且2019年已基本达到国家碘缺乏病消除相关标准。

Objective To understand the salt consumption of residents in a district of Tianjin city from 2017 to 2019,s.o as to provide support for scientific prevention and treatment of iodine deficiency disorders. Methods According to the sampling method stipulated in Tianjin Iodine Deficiency Surveillance Program,60 neighborhood committees(administrative villages) in 15 towns were selected every year,and 900 samples of edible salt were collected randomly from households.GB/T 13025.7-2012 direct titration method was used for quantitative detection. Results A total of 2 700 servings of edible salt were tested from 2017 to 2019,with a median salt iodine content of 25.90 mg/kg.Among them,2 236 were qualified iodized salt,260 were non-iodized salt,and 204 were unqualified iodized salt.The qualified rate of iodized salt,coverage of iodized salt,and consumption rate of qualified iodized salt were 91.64%,90.37%,and 82.81%,respectively.In 2019,the qualified rate of iodized salt,the coverage of iodized salt,and the qualified iodized salt consumption rate were significantly higher than before,which were 94.84%,94.78%,and 89.89%,respectively. Conclusion From 2017 to 2019,the technical indicators of iodized salt monitoring in a household in a district of Tianjin city show an upward trend year by year,and it has basically reached the national standards for the elimination of iodine deficiency diseases in 2019.
