江苏省6～12岁儿童甲状腺容积正常值

Normative values for thyroid volume for children aged 6～12 years in Jiangsu

目的 探讨江苏省 6～ 12岁儿童甲状腺容积正常值。方法 在江苏省人群尿碘中位数大于 10 0μg/ L碘营养状况正常的地区选择 6～ 12岁儿童用 B超作甲状腺容积测量 ,同时测其身高和体 ,计算体重表面积。结果 检查 6～ 12岁学龄儿童 2 10 0例 ,甲状腺容积随年龄和体表面积增加而增加 ,据此提出了江苏省儿童 6～12岁各年龄组甲状腺容积正常值范围和按体表面积计算的甲状腺容积正常范围。

Objective To define the upper normal limit of thyroid volume based on age and body surface area(BSA) for children aged 6~12 years in Jiangsu province.Methods Iodine status was assessed based on urinary iodine contents,thyroid volume was measured.Results Thyroid Volume of 2 100 schoolchildren aged 6~12 years in Jiangsu areas where iodine intake is normal,were determined by ultrasonography.It is shown that thyroid volume was related to age and BSA.The normative volume limits based on age were suggested.Normal limits of thyroid volume calculated based on body surfaced area are also reported.Conclusions These normative values are useful for IDD surveillance in Jiangsu province and also referential for revision of Chinese national normative values for schoolchildren.
