【摘要】：目的了解全国碘缺乏病防治现状,掌握2012-2015年新的盐碘标准实施后居民户碘盐使用的变化情况。方法四次碘盐监测方法相同,均按照《碘缺乏病监测方案》的要求,在全国31个省、自治区、直辖市(以下简称省份)和新疆生产建设兵团(以下简称兵团)以县为单位开展。结果结果显示,2012-2015年全国分别检测非高碘地区居民户食用盐848 728份、851 122份、849 192份和849 193份,全国碘盐覆盖率分别为98.76%、98.75%、98.62%和98.37%;居民户合格碘盐食用率分别为96.60%、96.26%、95.61%和94.57%,呈现持续下降的趋势;2012年全国碘盐碘含量均值为29.15 mg/kg,变异系数为19.69%,而到2015年,全国盐碘均数下降至25.37 mg/kg,变异系数下降至18.02%。结论全国碘盐覆盖率和合格碘盐食用率总体情况比较好,虽近年来呈现逐年下降的趋势,但碘盐的均匀度逐渐提升。
[Abstract]:Objective to understand the current situation of iodine deficiency disorders (IDD) prevention and control in China and to understand the changes of iodized salt use in households after the implementation of the new salt iodine standard from 2012 to 2015. Methods four times of iodized salt surveillance were carried out in 31 provinces, autonomous regions, municipalities directly under the Central Government (hereinafter referred to as provinces) and Xinjiang production and Construction Corps (hereinafter referred to as Xinjiang Corps) in accordance with the requirements of iodine deficiency Disorders Surveillance Program. The results showed that from 2012 to 2015, 848,728, 851,122, 849,192 and 849,193 edible salt samples were detected respectively in non-iodine areas. The national iodized salt coverage rate was 98.76% and 98.37%, respectively. The consumption rate of qualified iodized salt was 96.60% and 94.57% respectively. The average iodine content of iodized salt in China in 2012 was 29.15 mg/kg, variation coefficient, while in 2015, the national average of salt iodine decreased to 25.37 mg/kg, and the coefficient of variation decreased to 18.02. Conclusion the coverage rate of iodized salt and the consumption rate of qualified iodized salt in China are good in general. The uniformity of iodized salt is increasing gradually although it has been decreasing year by year in recent years.
