目的 监测分析桂林市区及所辖县8~10岁儿童尿碘含量的频数分布,为制定相应的干预措施提供科学依据。 方法 依据中华人民共和国卫生行业标准WS/T107-2006收集儿童尿样本进行检测。 结果 1 400份儿童尿碘检测值结果显示,8~10岁儿童尿碘水平＜50 μg/L的比率为1.29%,＜100 μg/L的比率为5.29%,达到国家碘缺乏病消除标准。 尿样本中尿碘水平≥200 μg/L的占73.64%(1 031/1 400),市区儿童样本≥200 μg/L的占66.20%(331/500),县城儿童样本中≥200 μg/L的占77.78%(700/900),其中有四个县的儿童样本≥200 μg/L的占86.75%(347/400)。 结论 桂林市8~10岁儿童尿碘样本检测的总体指标已达到国家标准,但县城儿童存在儿童尿碘含量偏高现象。

Objective To monitor and analyse the urinary iodine content of the frequency distribution of 8~10-year-old children at Guilin city and counties area and provide a scientific basis for lay down of appropriate interventions. Method The samples collected from children urine for testing basis on professional standard of health of P.R.China WS/T 107-2006. Results The 1 400 samples detection value of urinary iodine from children results showed.8~10 years old children urinary iodine level ＜50 μg/L ratio was 1.29% and ＜100 μg/L ratio was 5.29% and had up to the national iodine deficiency disorders elimination of the standard.In overall samples of urine,the urinary iodine levels ≥200 μg/L and above accounted for 73.64%(1 031/1 400),the urban sample of children ≥200 μg/L accounted for 66.20%(331/500) and the counties sample of children ≥200 μg/L accounted for 77.78% (700/900) and in which samples of children in four counties of ≥200 μg/L accounted for 86.75%(347/400). Conclusion The overall index of urinary iodine samples detected has reached the national standard,but there are high levels of phenomenon of children's urinary iodine in the counties.
