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。
Objective To understand the iodine content of salt consumed by residents in Daoli District of Harbin and accurately grasp the prevalence of iodine deficiency disorders and to identify the problems and take appropriate interventions to ensure that residents inhabit qualified iodized salt. Methods Random sampling and quantitative detection of residential salt samples, using GB / T13025.7-1999 redox titration. Results The iodized salt coverage rate of residents in Daoli District was> 93% from 2006 to 2008, and increased year by year. The passing rate of iodized salt of residents in the three years was> 96% and was stable. The iodized salt consumption rate of residents in three years> 92%. Conclusion The promotion and popularization of iodized salt have achieved some success. However, to ban non-iodized salt and realize universal consumption of iodized salt, we must insist on the consumption of qualified iodized salt for a long time.
