目的：研究按年龄和按体表面积分组的８～１０岁碘充足儿童甲状腺容积的正常值。方法：用Ｂ超测量４５０名８～１０岁碘充足儿童的甲状腺容积。结果：８、９、１０岁各年龄组甲状腺容积的正常上限值分别为４．１、４．７、５．０ｍｌ；分析８～１０岁碘充足儿童按体表面积分组的正常甲状腺容积上限值，体表面积为０．９ｍ２和１．０ｍ２儿童的甲状腺容积正常上限值分别为４．６５ｍｌ和５．０６ｍｌ，上述结果均低于ＷＨＯ／ＩＣＣＩＤＤ推荐的正常值。结论：ＷＨＯ／ＩＣＣＩＤＤ根据１２个欧洲国家的研究资料而推荐的儿童甲状腺容积正常值对中国儿童并不适用，有必要建立碘充足的中国儿童甲状腺容积的正常值。
PURPOSE: To study the normal thyroid volume of children aged 8 to 10 years with adequate iodine by age and body surface area. METHODS: The thyroid volume of 450 children aged 8 to 10 years with adequate iodine was measured by B ultrasound. Results: The normal upper limit of thyroid volume in each age group of 8, 9 and 10 was 4.1, 4.7 and 5.0ml, respectively. The normal thyroid volume of 8-10-year-old iodine-sufficient children was analyzed according to body surface area The upper limit of normal thyroid volume for children with body surface area of 0.9m2 and 1.0m2 was 4.65ml and 5.06ml, respectively. The above results were lower than the normal values recommended by the WHO / ICCIDD. Conclusion: The recommended thyroid volume in WHO / ICCIDD based on research data from 12 European countries is not suitable for Chinese children. It is necessary to establish a normal thyroid volume in Chinese children with sufficient iodine.
