摘要
目的 描述分析全国 8、9、10岁儿童尿碘含量的频数分布特征及其意义。方法 甲状腺容积的 B超法测量 ,尿碘含量的酸消化砷铈接触法检验 ,流行病学调查分析。结果 1全国 8、9、10岁儿童样本尿碘含量量均数、中位数和众数分别为 316 .9,2 73.0 ,2 5 0 .0μg/ L。 2儿童甲状腺容积“正常”、“增大”、“明显增大”3组尿碘含量中位数分别为 2 70 .2 ,339.5及 381.2μg/ L。3 1997、1999年 2次检查儿童尿碘中位数均大于 30 0μg/ L的 12个省份 ,儿童甲状腺容积“正常”、“增大”、“明显增大”3组的尿碘中位数分别为 35 8.2 ,373.5 ,413.6μg/ L ,容积增大尿碘增高现象尤其明显。结论 甲状腺肿大一部分可能与尿碘有关 。
Objective To discuss and analyze the frequence distriutions of urinary iodine (UI) contents of children aged 8,9,10 in China,1999.Methods B-ultrasound measurements of thyroid volume,acid digestion determination of UI,and investigation and analysis of epidemiology.Results ①The mean,medican and mode of UI contents (μg/L) in children sampled from whole country were 316.9,273.0 and 250.0 μg/L,respectively.②The contents of UI were divided into groups with thyroid volume measured by B-ultrasound.Thyroid volumes were broken down into three groups as normal,swelling,obvious swelling,and accordingly the medians of UI contents in these groups were 270.2,339.5 and 381.2 in μg/L.③On 12 high UI content provinces the medians were 358.2 ,373.5,413.6 μg/L,respectively,according to the normal,swelling and obvious swelling three groups divided by thyroid volume.They were highter than the medians in general population.Conclusions In high volume groups of thyroid volume,the UI contents are higher also;in 12 high UI content provinces this phenonenon is even prominent.
