1999年全国碘缺乏病监测资料汇总分析

An analysis and report of China national iodine deficiency disorders surveillance data in 1999

目的 汇总分析 1999年全国碘缺乏病的监测资料 (不含港、澳、台地区 )。方法 按人口容量比例概率抽样方法 (PPS)进行抽样 ,采用国家统一的标准方法进行各项指标的检测 ,并采取相应的的质量保障措施。结果 全国 31个省份的合格碘盐食用率为 80 .6 % ,8～ 10岁儿童尿碘中位数为 30 6 .0μg/ L ,触诊法甲状腺肿大率为 8.8% ;盐碘与尿碘 2项指标之间 ,呈现较好的相关性 ,单纯食用 15～ 2 0 mg/ kg加碘盐浓度的 8～ 10岁儿童尿碘中位数为 2 0 9.8μg/ L;全国居民户盐碘中位数为 42 .3mg/ kg,>40 mg/ kg的省份有 2 4个。结论 我国在 2 0 0 0年能够达到基本实现消除碘缺乏病的阶段目标 ;目前居民户加碘盐水平存在着盐碘浓度偏高的问题 ,应该下调加碘盐浓度 ,居民户加盐碘水平以 15～ 2 0 m g/ kg为宜 ;单纯食用合格加碘盐也能满足人群的碘营养需要。

Objective To summarize and analyze national Iodine Deficiency Disorder (IDD) surveillance data in 1999. Methods Sampling method is the one of probability proportional to size.Examination and determination of all the indicators are conducted by national unified standard methods, and a series of quality assurance measures are taken.Results Consuming rate of qualified iodized salt, median urinary iodine and total goiter rate of children aged 8~10 years old are 80.6%, 306.0 μg/L and 8.8% in 31 provinces in China, respectively. There is a good correlation between salt iodine at household level and urinary iodine, and median urinary iodine is 209.8 μg/L for the children who only consumed 15~20mg/kg iodized salt.Median salt iodine is 42.3mg/kg at household level, and there are 24 provinces in which median salt iodine is greater than 40mg/kg.Conclusions To reach the stage goal of eliminating IDD in our country by the year 2000 is full of promise.There is a problem of much higher concentration of iodine in salt at present. It should be done to decrease the concentration of iodine in salt, and appropriate content of iodine in salt at household level is in the range of 15~20 mg/kg. To consume the qualified iodized salt only can also meet the iodine nutrition need of the population.
