目的:动态了解贵州省居民户食用碘盐情况,及时发现问题并采取相应措施,为科学适宜的补碘提供可靠依据。方法:按照《全国碘缺乏病监测方案(2008、2012年修订)》,抽取全省88个县的乡、村居民户食用盐进行盐碘测定,数据经Excel2007和Spss19.0进行分析。结果:2009~2013年共检测居民食用盐129254份,其中合格碘盐125929份,不合格碘盐2823份,非碘盐502份,碘盐覆盖率、碘盐合格率、合格碘盐食用率和非碘盐率分别是99.61%、97.81%、97.43%、0.38%。从各年监测结果来看,非碘盐率控制得较好,各年度差异有统计学意义(x2=90.5,P<0.05)。碘盐覆盖率均>99%,各年度间比较,差异有统计学意义(x2=90.5,P<0.05)。碘盐合格率均>97%以上,各年度间比较差异有统计学意义(x2=32.19,P<0.05)。合格碘盐食用率除2012年外,各年均>97%以上,年度间比较差异有统计学意义(x2=80.14,P<0.05)。盐碘中位数波动在28.9~31.9之间,各年度盐碘中位数比较差异有统计学意义(P均<0.05)。结论:贵州省的碘盐监测各项数据良好,对碘缺乏病防治工作持续提供科学依据。
OBJECTIVE: To understand the situation of iodized salt consumed by residents in Guizhou Province in a timely manner, find out the problems and take corresponding measures in time, so as to provide a reliable basis for scientific and appropriate iodine supplementation. Methods: In accordance with the National Monitoring Program for Iodine Deficiency (2008, revised in 2012), salt and iodine were determined by salt intake in 88 counties of villages and villages in the province. The data were analyzed by Excel2007 and Spss19.0. Results: From 2009 to 2013, a total of 129254 residential salt samples were tested, of which 125929 were eligible for iodized salt, 2823 for unqualified iodized salt, 502 for non-iodized salt, coverage rate of iodized salt, qualified rate of iodized salt, Non-iodized salt rates were 99.61%, 97.81%, 97.43%, 0.38%, respectively. According to the monitoring results of each year, the non-iodized salt rate was controlled well, with significant difference in each year (x2 = 90.5, P <0.05). The iodized salt coverage rate was> 99%, with significant difference between years (x2 = 90.5, P <0.05). The qualified rate of iodized salt was> 97%, with significant difference between years (x2 = 32.19, P <0.05). Except for 2012, the eating rate of qualified iodized salt was over 97% in each year, with significant difference between years (x2 = 80.14, P <0.05). The median of salt iodide fluctuated between 28.9 and 31.9. There was significant difference in the median of salt and iodine in each year (P <0.05). Conclusion: The data of iodized salt monitoring in Guizhou Province are good, and provide a scientific basis for the prevention and control of iodine deficiency disorders.
