目的了解近年来新疆阿克陶县碘盐普及情况,掌握食盐加碘防治碘缺乏病措施落实情况,为进一步消除碘缺乏病工作提供科学依据。方法分析2007─2013年阿克陶县的碘盐监测结果。结果 2007─2013年共检测阿克陶县居民户食用盐2 040份,其中合格碘盐1 773份,不合格碘盐95份,非碘盐172份;碘盐覆盖率2007年最低为47.92%,自2009年起,连续5年达到95.00%以上;合格碘盐食用率最低年份为2007年,只有43.75%,随后逐年上升,2013年达到98.33%;非碘盐率由2007年的52.08%下降到2013年的1.33%;国家碘缺乏病“十一五”(2007—2010年)、“十二五”(2011—2013年)期间,阿克陶县居民户非碘盐率从14.58%降至0.45%,碘盐覆盖率从85.42%升至99.55%,碘盐合格率从92.68%升至97.40%,合格碘盐食用率从79.17%升至96.96%,非碘盐率(χ2=70.05)和合格碘盐率(χ2=11.56)差异有统计学意义(P<0.05);2013年如果按旧标准判定,碘盐合格率为99.66%,合格碘盐食用率98.33%,按新标准判定碘盐合格率则为98.64%,合格碘盐食用率97.00%。结论 2007年底新疆开展了贫困人口免费发放碘盐的工作使居民户合格碘盐食用率、碘盐覆盖率大幅提高,只有政府重视、财政支持、措施有效才是碘盐覆盖水平稳步提高的主要原因。
Objective To understand the popularization of iodized salt in Aktau County in Xinjiang in recent years and to master the implementation of the iodized salt prevention and treatment measures by iodized salt in order to provide a scientific basis for further eliminating iodine deficiency disorders. Methods The results of iodized salt monitoring in Aktau County from 2007 to 2013 were analyzed. Results A total of 2 040 edible salt samples were collected from households in Aktau County from 2007 to 2013, of which 1 773 were qualified iodized salt, 95 were unqualified iodized salt and 172 were non-iodized salt. The coverage of iodized salt in 2007 was 47.92% , Reaching 95.00% or above for 5 years in succession since 2009. The lowest rate of qualified iodized salt in 2007 was 43.75%, then increased year by year, reaching 98.33% in 2013. The non-iodized salt rate decreased from 52.08% in 2007 To 1.33% in 2013; national Iodine deficiency disease, “Eleventh Five-Year” (2007-2010), “Twelfth Five-Year” (2011-2013) From 14.58% to 0.45%, the coverage of iodized salt increased from 85.42% to 99.55%, the passing rate of iodized salt increased from 92.68% to 97.40%, the qualified iodized salt increased from 79.17% to 96.96% χ2 = 70.05) and qualified iodized salt rate (χ2 = 11.56), respectively. There was a statistically significant difference between the two groups (P <0.05). According to the old standard in 2013, the qualified rate of iodized salt was 99.66% and the qualified iodized salt rate was 98.33% The new standard to determine the qualified rate of iodized salt was 98.64%, 97.7% qualified iodized salt rate. Conclusion In late 2007, Xinjiang carried out the work of providing free iodized salt to the poor so that the consumption rate of qualified iodized salt and the coverage of iodized salt in residential areas increased substantially. Only by the government’s attention, financial support and effective measures are the main reasons for the steady increase of iodized salt coverage .
