摘要
目的全面、准确地掌握奉节县居民食用合格碘盐的情况,确保碘缺乏病防治措施的有效实施,为持续消除碘缺乏病工作提供科学依据。方法按照《重庆市碘盐监测方案》规定的抽样方法及盐碘测定方法对居民户食用盐进行监测。结果2004-2008年监测居民户家庭食用盐每年360份,共1800份,碘含量均数为30.75mg/kg,变异系数为21.06,年份间碘含量差异有统计学意义(F=13.755,P<0.05),呈明显线性下降趋势(R=0.12,P<0.05);碘盐覆盖率为99.39%,碘盐合格率为94.69%,合格碘盐食用率为94.11%,非碘盐率为0.61%,年份间差异均无统计学意义(P>0.05)。结论奉节县实现基本消除碘缺乏病阶段目标后,居民合格碘盐食用率保持在90%以上,成果巩固。各级政府应持续重视,完善监督监测机制,确保碘盐质量,以实现消除碘缺乏病的目标。
Objective To evaluate the quality of iodized salt consumed by residents living in Fengjie County, so as to provide scientific evidence for the prevention of iodine deficiency disease. Method Sampling and iodine measurement were performed according to ＂The Chongqing Municipal Iodized Salt Monitoring Program＂. Result 800 samples of edible salts were examined between 2004 and 2008. The mean iodine content was 30.75 mg/kg and the coefficient of variation was 21.06. There was a significant decrease in iodine content （F=13.755,P〈0.05） and the decrease was in a linear relationship （R=0.12, P〈0.05）. Coverage rate of iodized salt, rate of qualified iodized salt,rate of consumption of qualified and non-qualified iodized salt was 99.39% ,94.69% ,94.11% and 0.61%, respectively. Conclusion The rate of consumption of qualified iodized salt by residents living in Chongqing was above 90%. Government adopting a positive attitude towards the monitoring of iodized salt is required to achieve the goal of long term sustainable elimination of iodine deficiency disorders.
