2006年河南省碘盐监测结果分析

Analysis of iodized salt surveillance in Henan Province in 2006

目的了解河南省碘盐监测结果，分析监测结果中出现的问题。方法根据《全国碘盐监测方案》，第一层次每个一级生产、批发企业每月按东、南、西、北、中5个方位抽取一批9份盐样检测其含碘量：第二层次居民户每县（市、区）按东、南、西、北、中5个方位抽取9个乡（镇、居委会），每个乡（镇、居委会）抽取4个村（街道办事处），每个村（街道办事处）抽取8份盐样，每县（市、区）共收集288份盐样检测其含碘量，经人口加权计算出碘盐监测的各项指标。结果生产层次批质量合格率为98.2％（1459／1486）；加权后居民层次非碘盐率0．96％、碘盐覆盖率99．04％、碘盐合格率98．31％、合格碘盐食用率97．39％。结论河南省碘盐质量已经达到全省消除碘缺乏病碘盐的相应指标要求。

Objective To analyze the outcome of iodine salt surveillance in Henan Province in 2005. Methods Based on the National Scheme for Iodized Salt Surveillance, 9 samples of salt were randomly sampled from one batch in each first-degree wholesale enterprise every month. Meanwhile, 8 samples of salt were randomly collected in each 4 villages selected from 9 towns of 5 different directions of east, south, west, north and center in every county. As a result, a total of 288 samples underwent the detection of iodine concentration various rates of iodized salt were calculated by populatioa weighted method, Results For the industrial level, qualified batch rate was 98.2% （1459/1486）; for household level, non-iodized salt rate was 0.96%, iodized salt recovery rate was 99.04%, qualified iodize salt rate was 98.31%, and the coverage of qualified iodine salt reached 97.39%. Conclusions In term of the quality of iodine salt, the aim of elimination of iodine deficiency diseases （IDD） has been fulfilled in Henan Province.
