这项横断面研究旨在确定种族和环境对BMI和体脂百分比之间关系的影响，使用了144名居住在澳大利亚的日本男性和140名澳大利亚白人男性以及88名居住在日本的日本男性的样本。使用标准国际方法（国际运动人体测量促进协会方案）通过人体测量法评估身体组成。使用Durnin和Womersley（1974）公式预测身体密度，并根据Siri（1961）公式计算体脂百分比。日本和澳大利亚男性在身高、体质量和BMI方面存在显著的种族差异（P < 0.05），但在体脂百分比和身高校正的皮褶厚度总和方面没有观察到种族差异。生活在澳大利亚和日本的日本受试者之间的BMI-体脂百分比关系没有差异。显著（P < 0.05）从汇总的日本男性之间的比较中观察到BMI-体脂百分比关系的种族差异（年龄18-40岁，BMI范围16.6-32.8 kg/m2）和澳大利亚人（18-39岁，BMI范围16.1-31.4 kg/m2）表明，在任何给定的BMI值下，日本男性的体脂百分比都可能高于澳大利亚男性。根据分析，日本男性的体脂量估计与澳大利亚男性相当，BMI值比澳大利亚男性低约1.5个单位（分别为23.5 kg/m2和28.2 kg/m2）。结论是，在相同的BMI值下，日本男性的体脂沉积量大于澳大利亚白人。因此，与澳大利亚白人男性相比，日本男性可能需要更低的BMI临界点来识别肥胖个体。
This cross-sectional study aimed to determine ethnic and environmental influences on the relationship between BMI and percentage body fat, using a sample of 144 Japanese and 140 Australian-Caucasian men living in Australia, and eighty-eight Japanese men living in Japan. Body composition was assessed by anthropometry using standard international methods (International Society for the Advancement of Kinanthropometry protocol). Body density was predicted using Durnin and Womersley's (1974) equation, and percentage body fat was calculated from Siri's (1961) equation. Significant (P < 0.05) ethnic differences in stature, body mass and BMI were observed between Japanese and Australian men, but no ethnic differences were observed in their percentage body fat and height-corrected sum of skinfold thicknesses. No differences were found in the BMI-percentage body fat relationship between the Japanese subjects living in Australia and in Japan. Significant (P < 0.05) ethnic differences in the BMI-percentage body fat relationship observed from a comparison between pooled Japanese men (aged 18-40 years, BMI range 16.6-32.8 kg/m(2)) and Australians (aged 18-39 years, BMI range 16.1-31.4 kg/m(2)) suggest that Japanese men are likely to have a greater percentage body fat than Australian men at any given BMI value. From the analyses, the Japanese men were estimated to have an equivalent amount of body fat to the Australian men at BMI values that were about 1.5 units lower than those of the Australians (23.5 kg/m(2) and 28.2 kg/m(2), respectively). It was concluded that Japanese men have greater body fat deposition than Australian-Caucasians at the same BMI value. Japanese men may therefore require lower BMI cut-off points to identify obese individuals compared with Australian-Caucasian men.
