目的通过对张家口市居民户碘盐监测结果分析,了解该市居民户碘盐食用情况,发现碘盐推广使用中存在的问题,为本地持续消除碘缺乏病提供科学依据。方法对张家口市17个县(区),按行政区划分层抽样,经人口加权后计算出碘盐监测的各项指标。结果全市共监测85个乡镇(办事处)340个行政村(居委会),检测居民户盐样5011份,检出非碘盐33份,不合格碘盐94份,盐碘中位数为25.20mg/kg;加权后居民户家中食用盐非碘盐率0.65%、碘盐覆盖率99.35%、碘盐合格率98.14%、合格碘盐食用率97.51%。结论张家口市各项碘盐监测指标符合国家消除碘缺乏病指标要求。但不合格碘盐和非碘盐仍有检出,应加强监测和碘盐市场管理。
Objective To analyze the iodized salt monitoring results of residents in Zhangjiakou City to understand the consumption status of iodized salt in residents in this city and to find out the problems existing in the promotion and use of iodized salt so as to provide a scientific basis for the local elimination of iodine deficiency disorders. Methods Twenty-seven counties (districts) in Zhangjiakou City were stratified by administrative divisions and weighted by the population to calculate the indicators of iodized salt monitoring. Results A total of 5011 villages (residents’ committees) in 85 villages and towns (offices) were monitored in the city. 5011 salt samples of households were detected. 33 non-iodized salt, 94 non-qualified iodized salt and 25.20 mg of salt iodine were detected / kg; the salt content of non-iodized salt of household salt is 0.65%, the coverage of iodized salt is 99.35%, the qualified rate of iodized salt is 98.14% and the qualified iodized salt is 97.51%. Conclusion The monitoring indicators of iodized salt in Zhangjiakou City meet the requirements of the state to eliminate indicators of iodine deficiency disorders. However, unqualified iodized salt and non-iodized salt are still detected, monitoring and iodized salt market management should be strengthened.
