To compare the relationships between body mass index (BMI) and percentage body fat (%BF) in New Zealand Chinese aged 30-39 years and their European, Māori, Pacific Island, and Asian Indian counterparts.
Healthy Chinese (M20, F23) were selected to cover a wide range of BMI. European (M29, F37), Maori (M23, F23), Pacific Island (M15, F23), and Asian Indian (M29, F25) volunteers were drawn from existing data. Total and regional body fat and arm and leg lengths were measured by dual-energy X-ray absorptiometry.
For fixed BMI, Chinese had a higher %BF than European and less %BF than Asian Indian. At a %BF equivalent to a BMI of 30 kg/m2 in Europeans (WHO threshold for obesity), BMI values for Asian Indian and Chinese women were 5.8 and 2.2 units lower than European, respectively, and for Asian Indian and Chinese men, 8.2 and 3.0 units lower. Chinese had relatively shorter arm and leg lengths than Asian Indians and Europeans with a significantly higher ratio of central fat mass to limb fat mass.
The %BF-BMI relationships for Asian Indian and Chinese differ from Europeans and from each other and different BMI obesity thresholds may be required for these Asian ethnic groups.
比较30 - 39岁新西兰华裔与欧洲裔、毛利裔、太平洋岛裔和亚洲印度裔人群的体重指数（BMI）与体脂百分比（%BF）之间的关系。
选择健康的华裔（男性20名，女性23名），涵盖广泛的BMI范围。欧洲裔（男性29名，女性37名）、毛利裔（男性23名，女性23名）、太平洋岛裔（男性15名，女性23名）和亚洲印度裔（男性29名，女性25名）志愿者取自现有数据。采用双能X线吸收法测量全身和局部体脂以及手臂和腿部长度。
对于固定的BMI，华裔的%BF高于欧洲裔，低于亚洲印度裔。在欧洲裔中相当于BMI为30 kg/m²的%BF水平（世界卫生组织肥胖阈值）时，亚洲印度裔和华裔女性的BMI值分别比欧洲裔低5.8和2.2个单位，亚洲印度裔和华裔男性的BMI值分别低8.2和3.0个单位。华裔的手臂和腿部长度相对比亚洲印度裔和欧洲裔短，且中心脂肪量与肢体脂肪量之比显著更高。
亚洲印度裔和华裔的%BF - BMI关系不同于欧洲裔，且彼此不同，这些亚洲族群可能需要不同的BMI肥胖阈值。
