作者采用精确的超声扫描技术,在活体上测定271例健康人(年龄13～91岁)的甲状腺容积。受试者平均容积(±标准差)为18.6±4.5ml,其中男性139人,平均容积为19.6±4.7ml,女性132人平均容积为17.5±4.2ml男女之间有显著差异(F<0.001)。甲状腺容积与体重,年龄显著相关,可以公式表示:Y=1.97+0.21·X_1+0.06·X_2(其中Y为甲状腺容积,按毫升计;X_1为体重按公斤计,X_2为年龄按周岁计)。体重对甲状腺容积的影响约三倍于年龄对它的影响;男女甲状腺容积不同,完全被认为是两者体重不同的关系。
The authors used accurate ultrasound scanning techniques to determine the thyroid volume of 271 healthy subjects (aged 13-91 years) in vivo. The average volume (± SD) of subjects was 18.6 ± 4.5ml, of which 139 were males, the average volume was 19.6 ± 4.7ml, the average volume of 132 females was 17.5 ± 4.2ml There was a significant difference between men and women (F <0.001) . Thyroid volume is significantly related to body weight and age, and can be expressed as follows: Y = 1.97 + 0.21 · X_1 + 0.06 · X_2 (where Y is thyroid volume in milliliters; X_1 is body weight in kilograms; Weight of the thyroid volume of about three times the impact of age on it; men and women with different thyroid volumes, is completely considered the relationship between the weight of the two different.
