2006～2008年哈尔滨市道里区居民食用盐含碘量的监测分析

Analysis of surveillance on iodine salt among the local residents in Daoli District of Harbin from 2006 to 2008

目的了解哈尔滨市道里区居民食用盐中碘含量,准确地掌握碘缺乏病的流行动态,发现问题并采取相应的干预措施,保证居民食用合格碘盐。方法采取随机抽样并定量检测居民食用盐样本,用GB/T13025.7-1999氧化还原滴定法。结果2006～2008年道里区居民碘盐覆盖率均>93%,并逐年上升;3年间的居民碘盐合格率均>96%,并呈稳定状态;3年间的居民合格碘盐食用率均>92%。结论加碘食盐的推广、普及工作已经取得了一定的成效,但是要取缔非碘盐,实现全民食用碘盐,必须长期坚持食用合格碘盐。
