目的分析锦屏县碘盐监测情况,为持续做好碘缺乏病防治工作提供科学依据。方法按照《贵州省碘缺乏病监测(2012)方案》抽样要求,在东、西、南、北、中5个不同方位抽样,每片区随机抽取1个乡镇,每乡镇随机抽取4个行政村,每行政村随机抽检15户居民食用盐(≥50 g),按GB/T13025.7-2012标准的检测方法对居民户食盐碘含量进行测定。结果锦屏县2013-2015年居民户碘盐覆盖率为100%,碘盐合格率与合格碘盐食用率二者相同,分别为97.00%、95.33%和95.67%,差异无统计学意义(=1.220,P=0.545);2013年不合格碘盐9份、2014年14份、2015年13份,分别占当年检测份数的3.00%(9/300)、4.67%(14/300)和4.33%(13/300),各年度不合格碘盐检出率差异无统计学意义(=1.220,P=0.545)。结论多年来锦屏县碘盐各项指标均达国家消除碘缺乏病标准,且保持在稳定水平,但需继续做好碘盐监测工作,巩固防治成果。
Objective To analyze the monitoring status of iodized salt in Jinping County and provide a scientific basis for the prevention and treatment of iodine deficiency disorders. Methods According to the sampling requirements of “Guizhou province iodine deficiency disorders monitoring (2012) plan”, five different orientations were sampled in east, west, south, north and north. One township was randomly selected from each area, and four administrative villages were randomly selected from each township. Each administrative village randomly sampled 15 households salt (≥ 50 g), according to GB / T13025.7-2012 standard test methods for determination of household salt iodine content. Results The iodized salt coverage rate was 100% in Jinping household in 2013-2015. The qualified rates of iodized salt and iodized salt were the same, 97.00%, 95.33% and 95.67%, respectively, with no significant difference (= 1.220, P = 0.545); 9 unqualified iodized salt in 2013, 14 in 2014 and 13 in 2015, accounting for 3.00% (9/300), 4.67% (14/300) and 4.33 % (13/300). There was no significant difference in the detection rate of unqualified iodized salt in each year (= 1.220, P = 0.545). Conclusion Over the years, all indicators of iodized salt in Jinping County reached the national standard of eliminating iodine deficiency disorders, and remained stable. However, iodized salt monitoring should be continued to consolidate the results of prevention and treatment.
