Abstract:
Objective To observe the characteristics and statistics in the bi-variable distribution of thyroid volume (ml) and urine iodine level (μg/L) of children aged 8,9,10 years in China,1999.Methods Classing analysis.Results ①Data of 12982 cases collected from all country are analyzed with cluster method and three clusters are delimitated as follows;②in first cluster,according to the calculation of median,the volume of thyroid gland is small (2.2ml) and the level of urinary iodine is high (369.1μg/L);③in second cluster,the volume of thyroid gland is middle size (3.4ml) but the level of urinary iodine is significantly lower (88.0μg/L) than that in the first cluster;④in third cluster,the thyroid volume is highest (4.1ml) and the level of urine iodine is high (363.4μg/L),too;⑤the meanings of the classifying results are discussed in detail.Conclusions The results of the cluster analysis reported here and the typical analyses of the previous papers suggested that no low iodine problems be found out but the correlation between the increasing of thyroid volume and the higher level of urine iodine be observed by us in the studies.
