背景资料：环境条件对发育的影响，包括生长、成熟和遗传潜力的实现，可以通过研究同一人口中不同种族群体之间的差异来确定。本研究的目的是：（i）比较31名日本人和99名高加索人青春期前男孩以及50名日本人和98名高加索人青春期后男孩基于种族和成熟阶段的各种人体测量和身体组成参数;（ii）评估体重指数（BMI）及其与其他体脂评估方法的关系。使用生物电阻抗，近红外线相互作用和屠宰皮肤皮褶equations.Results：体重和身高在统计学上较低的日本人比高加索受试者的体脂百分比进行测量。不同种族之间的体脂没有差异，但日本受试者的无脂体重水平在统计学上较低。在白人受试者中，达到成熟时无脂肪质量的增加和体脂的减少更大。BMI与其他方法的协议是好的，在所有的组，但低于日本比高加索subjects.Conclusion：种族之间的身高和体重差异表明不同的遗传潜力范围。不同种族之间的体脂量没有差异，但白人受试者达到成熟时的变化程度更大。如果这一差异在两组之间得以维持，那么多年后，日本受试者的脂肪积累会更大。
Background: The effect of environmental conditions on development, including growth, maturation and the fulfillment of genetic potential, can be identified through the study of the variations found among different ethnic groups in the same population. The objectives of the present study were: (i) to compare the various anthropometric and body composition parameters based on ethnicity and maturation stage in 31 Japanese and 99 Caucasian prepubescent boys and 50 Japanese and 98 Caucasian post-pubescent boys; and (ii) to assess body mass index (BMI) and its relationship with other methods of body fat evaluation.Methods: The percentage of body fat was measured using bioelectrical impedance, near-infrared interactance and Slaughter cutaneous skinfold equations.Results: Weight and height were statistically lower for the Japanese than the Caucasian subjects. There were no differences in body fat between the ethnic groups, but the Japanese subjects had statistically lower levels of fat-free mass. The gain in fat-free mass and the loss in body fat when attaining maturation were greater in the Caucasian subjects. The agreement of BMI with other methods was good in all of the groups but lower for the Japanese than for the Caucasian subjects.Conclusion: Height and weight differences between the ethnic groups indicated distinct genetic potential ranges. The body fat mass did not differ between the ethnic groups, but the degree of changes when attaining maturation in the Caucasian subjects was greater. If this difference were to be maintained between the groups then years later there would be a greater accumulation of fat in the Japanese subjects.
