目的 观察 8～ 10岁儿童甲状腺容积 (m l)、尿碘 (μg/ L)联合分布特征以及相关统计值 ,以了解 8～10岁儿童甲状腺容积与尿碘含量之间的关系。方法 聚类分析法。结果 1全部 12 982例用聚类法分成三群 ;2第一群按中位数计算 ,甲状腺容积小 (2 .2 m l)但尿碘值较高 (36 9.1μg/ L) ;3第二群甲状腺容积属中等 (3.4m l)但尿碘值低 (88.4μg/ L) ;4第三群甲状腺容积大 (4 .1m l)同时尿碘值高 (36 3.4μg/ L) ;5对各群的划分及其意义做了详细讨论。结论 聚类分析以及以前的典型分析均发现了甲状腺容积增大与尿碘值高的联系
Objective To observe the distribution of thyroid volume (m l), urinary iodine (μg / L) and related statistics in children aged 8-10 years to understand the relationship between thyroid volume and urinary iodine content in children aged 8-10 years. Method Clustering analysis. Results 1 All 12 982 cases were divided into three groups by clustering method. 2 The first group had a small median volume (2.2 ml) but a high urinary iodine value (36.91 μg / L) The group of thyroid volume was moderate (3.4ml) but the urinary iodine value was low (88.4μg / L). The third group had a large thyroid volume (4.lm l) and high urinary iodine value (36.4μg / L) Group division and its significance have been discussed in detail. Conclusions Clustering analysis and previous typical analysis showed that the increase of thyroid volume was associated with a high urinary iodine value
