【摘要】：目的掌握山西省非高碘县及高碘县的非高碘地区新的盐碘标准实施后居民户碘盐使用情况。方法按照《碘缺乏病监测方案》的要求,2012年-2015年在全省11个市109个非高碘县(市、区)及10个高碘县(市、区)所辖非高碘地区,按东、西、南、北、中划分5个抽样片区,在每个片区各随机抽取1个乡(镇、街办)。在每个乡(镇、街办),随机抽取4个行政村(居委会);在每个行政村(居委会),随机抽检15户居民食用盐,进行盐碘检测。盐碘含量采用直接滴定法测定,川盐及其他强化盐采用仲裁法测定。结果 2012-2015年,碘盐覆盖率总体上一直维持在95%以上,全省盐碘中位数逐年下降,以新标准18-33mg/kg计,全省合格碘盐食用率逐年升高;2012年-2014年,以过渡期标准18-50mg/kg计,合格碘盐食用率总体上一直在90%以上,但≤90%的县数在增加;2015年,以新标准18-33mg/kg计,合格碘盐食用率为92.52%,但有16个县碘盐覆盖率㩳95%,有27个县≤90%,占到了全部县数的22.7%(27/119)。结论新的盐碘标准实施后,山西省新旧标准碘盐总体上过渡平稳,但存在合格碘盐食用率不达标的县数扩大的倾向,应引起重视。
[Abstract]:Objective to understand the use of iodized salt in households after the implementation of the new salt iodine standard in non-high iodine counties and non-high iodine areas of Shanxi Province. Methods according to the requirement of iodine deficiency Disorders Surveillance Program, from 2012 to 2015, 109 non-iodine counties (cities, districts) and 10 non-iodine high iodine counties (cities, districts) in 11 cities of the province were divided into 5 sampling areas according to east, west, south, north and middle. In each section of each random sampling of 1 township (town, street office). In each township (town, street office), 4 administrative villages were randomly selected (neighborhood committee); in each administrative village (neighborhood committee), 15 households were randomly selected for salt consumption and iodine salt detection. The iodine content of salt is determined by direct titration, and the salt and other fortified salts by arbitration. Results from 2012 to 2015, the coverage rate of iodized salt was kept above 95%, and the median of salt iodine decreased year by year. The consumption rate of qualified iodized salt increased year by year in terms of the new standard 18-33mg/kg and the transitional standard 18-50mg/kg from 2012 to 2014. The consumption rate of qualified iodized salt was above 90%, but the number of counties 鈮，
