目的了解福建省厦门市水源性高碘村及相邻村水碘、学生碘营养状况及家中食用盐含碘量,为制订科学防治措施提供依据.方法 2008年,在厦门市选择水源性高碘村翔安区洪前行政村前边村及相邻的东莲村、东山村、大中村共4个自然村为调查点,4个自然村每村各采集1份自来水厂末梢水样和村民家中的所有井水水样.测定水碘,按统一设计的登记表在采水样时同时记录采样点基本情况;对4个村7～13岁所有在校学生进行甲状腺触诊检查,并采集尿样和家中盐样,采用砷铈催化分光光度法测定尿碘,采用直接滴定法测定盐碘.结果在4个调查村,共采集4份自来水厂末梢水,水碘均为1.5μg/L;共有水井237 口,水碘范围为0.1～506.0μg/L;水碘<10μg/L的井占18.6%(44/237);水碘在10～150μg/L的井占73.4%(174/237);水碘>150μg/L的井占8%(19/237).共检测学生尿样79份,尿碘中位数为153.3μg/L.尿碘>200～<300 μg/L 的占11.4%(9/79),300～<500μg/L的占12.7%(10/79),500～<800μg/L的占7.6%(6/79).触诊法检查学生79名,甲状腺肿大率为11.4%(9/79);检测学生家中盐样71份,碘盐覆盖率为77.5%(55/71).结论调查村井水水碘分布范围大;要针对不同人群分别采取宣传高碘危害和碘缺乏危害的知识,不断提高其健康意识.

Objective To investigate the current conditions of water iodine,childrens'iodine nutrition and residents'edible circumstance of iodized salt in the villages with high iodine in drinking water and the adjacent three villages in Xiamen city of Fujian province.Methods Four natural villages of Qianbian,Donglian,Dazhong and Dongshan of Xiangan county were chosen as survey spots in 2008.In each village,one running water sample and all well water samples were collected to obtain the benchmark for each location.All children aged 7-13 year in the four villages underwent thyroid palpation and were selected to measure the urine iodine and the salt iodine.The water iodine and urine iodine were determined by As3+-Ce4+ catalytic spectrophotometry digestion,salt iodine was determined by direct titration.Results In four investigated villages,iodine of four running water samples were all 1.5μg/L.The range of 237 well water iodine samples was from 0.1 μg/L to 506.0 μg/L.There were 18.6% (44/237)specimens in which the well water iodine less than 10 μg/L,73.4%(174/237)between 10 μg/L and 150 μg/L and 8%(19/237)more than 150μg/L.The median of urinary iodine was 153.3 μg/L in 79 urine samples,which was 114%(9/79)more than 200μg/L and less than 300μg/L,12.7%(10/79)equal or more than 300 μg/L and less than 500μg/L,7.6%(6/79)equal or more than 500μg/L and less than 800 μg/L in all samples.Seventy-nine students were examined by palpation and the total goiter rate of children measured was 11.4% (9/79).Seventy-one samples of iodine salt were detected and the coverage rate of iodized salt was 77.5%(55/71).Conclusions The well water iodine contents have a wide distribution in the investigated villages.We should enhance the community awareness by educating them on the damage of iodine excess and iodine deficiency.
