现行碘盐浓度与高碘甲状腺肿之间关系的探讨

Investigations on the relations between the present iodine salt density and iodine excess goitor

目的 通过对山西省碘缺乏病 6年监测结果的分析以及与山西省高碘地区甲状腺肿对比研究 ,探讨全民食盐加碘后尿碘浓度的变化是否会引起高碘甲状腺肿。方法 运用山西省 6年病情监测结果及高碘地区调查资料。结果 1碘盐中位数逐年上升并趋于稳定 ,基本上控制在 2 0～ 6 0 m g/ kg;2儿童尿碘中位数逐年上升 ,并稳定在 30 0～ 40 0 μg/ L 左右 ;3儿童甲状腺肿大率逐年下降 ,从 1995年 10 .9%下降至 2 0 0 0年的 3.7% ;4高碘地区甲肿率为 11.1% ,尿碘中位数为 1111.2 μg/ L。结论 现行碘盐浓度以及儿童尿碘中位数在 40 0 μg/

Objective Through the analyses of six gears inspection results on iodien deficiency disorders in ShanXi province and a contrast study on goitor in iodine excess regions in ShanXi province,this article is aimed to investigate whether the changes of urinary iodine density will cause goitor after adding iodine to the whole people's salt.Methods Inspection results on patient's conditions for 6 years in ShanXi province and research material in iodine excess regions are used.Results ①The medium number of iodine salt is in creasing each year and has levelled off,generally controlled between 20 and 60 mg/kg;②The medium number of urinary iodine is increasing each year and remains stable between 300 μg/L and 400 μg/L.③The percentage of goitor is decreasing each year,from 1995's 10.9% to 2000's 3.7%.④The percentage of goitor in iodine excess regions is 11.1%;the medium number of urinary iodine is 1111.2 μg/L.Conclusions The present iodine salt density and the medium number of children's urinany iodine will not cause iodine excess harmness.
