本文使用Ｂ超对河南省农村非缺碘地区７～１４岁正常儿童的甲状腺体积进行调查和研究，结果显示正常儿童甲状腺体积依不同年龄组其均值分别为：７岁３．１０ｍｌ；８岁３．７５ｍｌ；９岁５．１６ｍｌ；１０岁５．８８ｍｌ；１１岁６．６２ｍｌ；１２岁７．３９ｍｌ；１３岁９．２１ｍｌ；１４岁９．８３ｍｌ。本文对甲状腺体积与年龄、性别、身高、体重的关系的研究显示：各年龄组甲状腺体积无性别差异；甲状腺体积与年龄的依存关系最为密切，其次为体重，再次为身高。文章认为，农村正常儿童体积的研究，对农村广大病区儿童病情的Ｂ超测量结果有一定的比较，评判作用。
In this paper, the thyroid volume of thyroid in normal children aged 7-14 years in non-iodine-deficient areas of Henan province was investigated and studied. The results showed that the average thyroid volume of normal children was 3.10ml at 7 years old and 8 years old at 3 years .75 ml; 9 years old 5.16 ml; 10 years old 5.88 ml; 11 years old 6.62 ml; 12 years old 7.39 ml; 13 years old 9.21 ml; 14 years old 9.83 ml.
