浙江省沿海地区居民碘营养状况分析

Surveys on iodine nutrition of population in coastal areas of Zhejiang Province

目的了解目前浙江省沿海地区居民的碘营养状况,全面评估浙江省沿海地区不同人群的碘营养水平。方法对纳入本次调查的居民的尿碘、水碘、盐碘情况进行调查,采用砷铈催化分光光度测定方法检测水碘、尿碘;硫代硫酸钠法测定盐碘。结果本次调查,浙江省沿海地区水碘浓度中位数为5.7μg/L,食用盐盐碘浓度中位数为27.0 mg/kg,沿海居民尿碘中位数为165.9μg/L,尿碘<100μg/L的比率为24.8%,尿碘≥300μg/L的比率为18.8%,其中沿海城市、沿海农村居民尿碘中位数分别为156.4μg/L、180.3μg/L。结论浙江省沿海地区居民尿碘、盐碘总体水平处于推荐范围内,从总体上来说浙江省沿海居民碘营养水平处于较适宜水平。

Objective To evaluate the status of iodine nutrition of inhabitant in coastal areas of Zhejiang Province to explore the status of iodine nutrition in different areas of population.Methods To research the level of urinary iodine and water and the concentration of the iodine salt for the inhabitant,the level of urinary iodine and water iodine were measured by spectrophotometer method,iodine salt level was measured by sodium subsulfite method.Result From the result of survey,we can see that the median water iodine of the coastal Zhejiang is 5.7 μg/L,the mean salt iodine of the coastal Zhejiang is 27.0 mg/kg,and the median urinary iodine of the population in the coastal Zhejiang is 165.9 μg/L,the percentage which is less than 100 μg/L is 24.8%,and the percentage which is more than 300 μg/L is 18.8%,and the median urinary iodine of coastal county,coastal city is 156.4 μg/L,180.3 μg/L,respectively.Conclusions The level of urinary iodine and salt iodine are overall in recommended range,then the inhabitant in coastal areas of Zhejiang Province show a good iodine nutritional status.
