目的 了解山西省高碘地区停供碘盐后人群碘来源改变情况以及不同人群的碘营养状况,为制订或调整高碘地区防治策略提供科学依据,并探讨停供碘盐的水碘切点值.方法 2010年,在山西省高碘地区选择水碘含量分别在0～,50～,100～,150～,300～,≥500μg/L范围内,且无碘盐食用率均为100％的6个村作为调查点.每个调查点抽取20名8～ 10岁儿童及其家中18～50岁育龄期妇女和18 ～ 60岁成年男子作为调查对象.采取3日回顾询问法对调查对象进行膳食调查.同时采集当地生活饮水,自产主、副食食品和调查对象随意1次尿样,砷铈催化分光光度法检测各样品碘含量.结果 ①水碘为25.9、70.6 μg/L的调查点,上述3种人群的尿碘中位数均在100～ 199 μg/L,碘营养水平为适宜；水碘为109.0 μg/L的调查点,上述3种人群的尿碘中位数均在200 ～ 299 μg/L,碘营养水平为超过适宜量；水碘为225.8、430.0、581.2 μg/L的调查点,上述3种人群的尿碘中位数均≥300 μg/L,碘营养水平为碘过量.②各调查点3种人群碘摄入量均达到并超过了世界卫生组织/联合国儿童基金会/国际控制碘缺乏病理事会(WHO/UNICEF/ICCIDD)推荐的膳食碘的推荐摄入量标准(8～10岁儿童≥120 μg/d,育龄期妇女及成年男子≥150μg/d).水碘在581.2μg/L的调查点3种人群碘摄入量均超过了日安全摄入量上限(8～ 10岁儿童≤800 μg/d;育龄期妇女及成年男子≤1000μg/d).③在各调查点,饮水碘的摄人量占总摄入量的比例随水碘含量升高而增大,在水碘含量超过100μg/L后,饮水碘的摄入超过食物碘的摄入,成为人体碘的主要来源.结论 山西省高碘地区停供碘盐后,在水碘超过100μg/L的村中,水碘成为人群最主要的碘来源,且人群碘营养水平为超过适宜量或碘过量,建议山西省高碘地区划定标准的水碘含量切点值设为100 μg/L.

Objective To study the changes of iodine source and the nutritional status of iodine after termination of iodized salt supply in the areas with different water iodine concentrations in Shanxi province,in order to provide scientific bases for developing strategies on control and prevention of iodine deficiency disorders,and to study the cut-off value of water iodine level where iodized salt supply should be stopped.Methods In 2010 in Shanxi province,6 villages with 100％ of non-iodized salt consumption rate were selected as the survey spots based on the iodine concentration in drinking water of 0-,50-,100-,150-,300-,≥500 μg/L.Villages'iodized salt supply was terminated thoroughly.In each village,20 children aged 8 to 10 were selected.At the same time,women of childbearing age 18 to 50 years old and adult men aged 18 to 60 were selected from the same families as the children.Diet surveys were conducted by the method of 3 days recall on all subjects.Drinking water samples,staple foods,supplementary foods and urinary samples of all subjects were collected and the iodine concentration was determined by arsenic-cerium catalytic spectrophotometry.Results ①In the villages of water iodine 25.9,70.6 μg/L,the medians urinary iodine of children,women and men were all ranged from 100 to 199 μg/L,which meant their iodine nutrition levels were appropriate.In the village of water iodine 109.0 μg/L,the medians urinary iodine of children,women and men were all ranged from 200 to 299 μg/L,which meant their iodine nutrition levels were more than appropriate.In the villages of water iodine 225.8,430.0,581.2 μg/L,the medians urinary iodine of children,women and men were all ≥ 300 μg/L,which meant their iodine nutrition levels were too high.②)In all the 6 villages,the intaking amount of iodine met and exceeded the standard recommended intake of dietary iodine by ICCIDD/UNICEF/WHO (8 to 10-year-old children ≥ 120 μg/d,women of childbearing age and adult men ≥ 150 μg/d).But in the village of water iodine 581.2 μg/L,the iodine intake was exceeded the daily maximum safe intake (children aged 8 to 10 ≤800 μg/d,women of childbearing age and adult man ≤ 1000 μg/d).③The amount of iodine ingestion from drinking water was increased with the water content of iodine.When water iodine exceeded 100 μg/L,the amount of iodine ingestion from drinking water was higher than from food intaking,and became a main resource of iodine in the human body.Conclusions In the counties of iodine concentration in drinking water above 100 μg/L in high iodine areas of Shanxi province,the water iodine becomes the most important source of iodine,and iodine nutritional level is more than appropriate or possible excess.It is recommended that in areas of high water iodine of Shanxi province,the standard cut-point of water iodine value is set to 100 μg/L.
