目的:了解剑河县碘缺乏病防治现状,为今后碘缺乏病防治工作提供科学依据。方法:按照《全国碘盐监测方案》,对剑河县居民食盐进行采样和测定;采用尿中碘的砷铈催化分光光度测定方法对8~10岁学生尿样进行测定。结果:新标准实施前(2006~2011年)6年中共检测碘盐1735份,盐碘均数为33.21 mg/kg;新标准实施后(2012年)共检测碘盐300份,盐碘均数为30.95 mg/kg,新标准实施前后碘盐覆盖率均达到100.00%,合格碘盐食用率分别为97.52%和99.00%。2009、2011年两年共检测学龄儿童尿样200份,尿碘中位数为335.6μg/L,尿碘值<100μg/L的样本占5.00%(其中<50μg/L样本占1.00%),100~200μg/L占13.00%,200~300μg/L占22.50%,≥300μg/L占59.50%。结论:剑河县儿童机体碘营养状况充足;新标准实施后碘盐质量得到很好的改善。
Objective: To understand the status quo of prevention and treatment of iodine deficiency disorders in Jianhe County and to provide a scientific basis for the prevention and treatment of iodine deficiency disorders in the future. Methods: According to “National iodine salt monitoring program”, residents of Jianhe County, salt sampling and determination; urinary iodine arsenic cerium catalytic spectrophotometry for 8 to 10-year-old students urine samples were measured. Results: Before the implementation of the new standard (2006 ~ 2011), 1735 iodized salt were detected and the average iodine number was 33.21 mg / kg. After the implementation of the new standard (2012), 300 iodized salt, 30.95 mg / kg, the iodized salt coverage reached 100.00% before and after the implementation of the new standard, and the qualified iodized salt consumption rates were 97.52% and 99.00% respectively. In 2009 and 2011, a total of 200 urine samples were collected from school-aged children. The median urinary iodine was 335.6 μg / L and the urinary iodine value was less than 100 μg / L, accounting for 5.00% of which (50 μg / L sample accounted for 1.00%). L accounted for 13.00% with 100 ~ 200μg / L, 22.50% with 200 ~ 300μg / L, and 59.50% with ≥300μg / L. Conclusion: The iodine nutrition status of children body in Jianhe County is adequate; the quality of iodized salt is improved after the new standard is implemented.
