2008～2013年黔东南州居民碘盐监测结果分析

Anlysisnl on iodized salt situation monitoning of households in qiandongnan Prefecture from 2008 to 2013

目的:为进一步巩固消除碘缺乏病成果,继续为碘缺乏病防治提供科学依据。方法:采用GB13025.7-1999直接滴定法,测定食用盐中碘含量。采用全国碘盐监测信息管理系统建立数据库,用SPSS18.0软件进行统计分析。结果:不同年份间合格碘盐食用率差异有统计学意义(x2=71.16,P<0.001),不同年份盐碘均值差异有统计学意义(F=729.10,P<0.001),粗粒盐与精制盐碘盐覆盖率差异无统计学意义(x2=0.164,P>0.05)。结论:2013年居民食盐碘含量已经明显低于其他年份,证明新标准碘盐已经成为市场主要流通碘盐,应加大碘缺乏病监测力度。精制盐合格率明显高于粗盐,粗盐主要来源于从江县,粗粒盐改精制盐健康教育工作有待继续加强。

Objective： In order to further consolidate the results of eliminating iodine deficiency disorders[ IDD], continue to provide scientific basis for prevention and control of iodine deficiency disorders. Methods： The GB13025.7 - 1999 direct titration method, determining the iodine content of edible salt. To establish a data bank by using the national iodized salt monitoring information management system , Counting and analysing by using SPSS18.0 software . Results： Rate of qualified iodized salt consumption differences between different years （X^2 = 71.16, P〈0. 001 ） ; Different years salt iodine mean difference was statistically significant （ F = 729.10, P〈 0. 001 ）. Coarse salt and there was no statistically significant difference of refined salt iodized salt coverage （X^2 = 0.164, P 〉 0.164）. Discussion： In 2013 , the iodine content of edible was significantly lower than other years, It shows that the new standards iodized salt has become the main salt in the market, We should increase the intensity of IDD monitoring. The qualified rate of refined salt was significantly higher than that of coarse salt, refined salt mainly comes from CongJiang county, The health education of coarse salt change into the refined salt needs to be strengthened.
