2008—2014年宁夏回族自治区固原市碘盐监测结果分析

Iodized salt monitoring results in Guyuan of Ningxia from 2008 to 2014

目的分析宁夏回族自治区（简称宁夏）固原市碘盐监测结果，为碘缺乏病防治提供依据。方法采用描述性流行病学方法，对宁夏固原市2008—2014年碘盐监测数据进行回顾性分析，比较不同年份碘盐合格率、合格碘盐食用率差异。结果2008—2014年固原市居民户碘盐合格率为96．95％（9918／10230），范围在96．03％～97．93％，不同年份碘盐合格率比较差异有统计学意义（Х^2=18．24，P〈0．05）；合格碘盐食用率为96．22％（9918／10308），范围在95．18％～97．59％，不同年份比较差异有统计学意义（Х^2=38．99，P〈0．05）：食用盐碘的中位数为31．4mg／kg，范围在26．2～34．9mg／kg。结论固原市碘盐合格率和合格碘盐食用率保持在较高水平．现行的居民食用盐盐碘含量能满足固原市碘缺乏病防治的需要。

Objective To analyze the monitoring results of iodized salt in Guyuan of Ningxia, and to provide a basis to prevent and control iodine deficiency disorders. Method Descriptive epidemiological method was used to analysis the data of iodized salt from 2008 to 2014, the differences of the qualified rate of iodized salt and the consumption rate of qualified iodized salt in different years were compared longitudinally. Results From 2008 to 2014, the residents iodized salt qualified rate was 96.95% （9 918/10 230）, ranged from 96.03% to 97.93% in Guyuan, qualified rate of iodized salt in different years was significantly different （Х^2 = 18.24, P 〈 0.05）; The consumption rate of qualified iodized salt was 96.22% （9 918/10 308）, ranged from 95.18% to 97.59%, there was significant difference among different years （Х^2 = 38.99, P 〈 0.05）; The median iodine concentration in salt was 31.4 mg/kg, and ranged from 26.2 to 34.9 mg/kg. Conclusions The qualified rate of iodized salt and the consumption rate of qualified iodized salt are kept at a high level. The current iodine content of salt is enough to prevent and control iodine deficiency disorders.
