目的了解2013年正阳县居民食用碘盐情况,为巩固碘缺乏病防治成果提供科学依据。方法采用多阶段分层随机抽样的方法进行居民户盐样采集;采用GB/T130257-2012中的直接滴定法进行盐碘含量检测。结果应监测居民食用盐300份,实际监测300份,其中合格碘盐281份,不合格碘盐10份,非碘盐9份;碘盐覆盖率、碘盐合格率、合格碘盐食用率以及非碘盐率分别为97.00%,96.56%,93.67%和3.00%。结论 2013年正阳县碘盐覆盖率、碘盐合格率、合格碘盐食用率达到国家消除碘缺乏病标准,但相比过去3年,三者均有不同程度的下降,而非碘盐率有上升趋势。为巩固碘缺乏病的防治成果,应完善可持续消除碘缺乏病工作机制,有效开展健康教育与促进,强化碘盐及非碘盐的监督监测与管理。
Objective To understand the consumption of iodized salt by residents in Zhengyang County in 2013 and provide a scientific basis for consolidating the results of iodine deficiency disorders prevention and treatment. Methods A multi-stage stratified random sampling method was used to collect salt samples from households. Salt iodine content was measured by direct titration in GB / T130257-2012. Results The residents should be monitored 300 servings of salt, the actual monitoring of 300, of which 281 were qualified iodized salt, unqualified iodized salt 10, non-iodized salt 9; iodized salt coverage, qualified rate of iodized salt, qualified iodized salt consumption and Non-iodized salt rates were 97.00%, 96.56%, 93.67% and 3.00% respectively. Conclusion In 2013, the coverage rate of iodized salt, the qualified rate of iodized salt and the qualified rate of iodized salt in Zhengyang County reached the national standard of eliminating iodine deficiency deficiency. However, compared with the past three years, all three had different degrees of decline, There is an upward trend. In order to consolidate the prevention and treatment of iodine deficiency disorders, we should improve the working mechanism for the sustainable elimination of iodine deficiency disorders, effectively carry out health education and promotion, and strengthen the supervision, monitoring and management of iodized salt and non-iodized salt.
