[目的]了解东港区阶段消除碘缺乏病(IDD)后居民户食用盐状况,对于可持续消除碘缺乏病具有指导意义。[方法]用GB/T13025.7-1999《制盐工业通用试验方法碘离子的测定》检测居民家食盐中碘含量。[结果]2005~2007年共检测960份食盐,合格892份,合格率为93.7%;合格碘盐食用率为92.9%。盐碘含量为0~45.8 mg/kg,均值(28.0±6.5)mg/kg。不同年份间合格碘盐食用率的差异无统计学意义(P>0.05);东、西部乡镇合格碘盐食用率的差异有统计学意义(P<0.01)。[结论]东港区居民户碘盐覆盖率、合格碘盐食用率总体已经达到标准要求;部分乡镇存在粗盐、无碘盐冲销市场情况。
[Objective] To understand the status of household salt consumption after the elimination of iodine deficiency deficiency (IDD) in Donggang district and to guide the sustainable elimination of iodine deficiency deficiency. [Method] The content of iodine in common household salt was determined by GB / T13025.7-1999 “Determination of iodide in common salt industry”. [Result] A total of 960 samples of salt were tested from 2005 to 2007, with a passing rate of 892. The pass rate was 93.7%. The qualified iodized salt consumption rate was 92.9%. Salt iodine content of 0 ~ 45.8 mg / kg, mean (28.0 ± 6.5) mg / kg. There was no significant difference in the eating rate of qualified iodized salt in different years (P> 0.05). There was significant difference in the eating rate of qualified iodized salt between towns in the east and west (P <0.01). [Conclusion] The coverage rate of iodized salt and the rate of qualified iodized salt in Donggang area have all met the standard requirements. In some towns and cities there are coarse salt and no iodized salt to offset the market situation.
