To compare the relations of adiposity and body fat distribution to body mass index (BMI) in Australians of Aboriginal and European ancestry.
Cross-sectional volunteer samples.
Australian Aboriginal communities in remote central and northern Australia, urban European Australians resident in Melbourne, Australia.
Healthy Aboriginal (130 women, 120 men) and European Australians (100 women, 47 men) with a BMI<30 kg/m(2), aged 18-35 y; all women were nonpregnant.
Anthropometric variables and resistance-using a four-terminal impedance plethysmograph-were measured.
Aboriginal women and men were significantly shorter and weighed less than European Australians (P<0.05). Aboriginal women had a significantly larger waist circumference and waist-to-hip ratio (WHR, P<0.0005) compared to European Australian women. The sum of four skinfold thicknesses (SFT) (S4) and trunk SFT was higher in Aboriginals as compared to European Australian women (P<0.0005); however, limb SFT tended to be lower (P=0.06). On the other hand, BMI was significantly lower in Aboriginals compared to European Australian men (P=0.011), as was hip circumference (P=0.001); however, WHR was significantly (P=0.007) higher. On regression analysis, Aboriginal women and men were significantly heavier than European Australians for the same height(2)/resistance (surrogate for fat-free mass) and S4 (surrogate for subcutaneous fat); and that Aboriginal men had a significantly higher BMI (by 1.2 kg/m(2); P<0.0005) for any given S4 and height(2)/resistance values, compared to European Australian men.
Aboriginal and European Australians have a significantly different body fat distribution and fat mass for a given body weight or BMI. Use of the World Health Organization recommended BMI ranges to determine weight status may be inappropriate in Australian Aboriginal people.
比较澳大利亚原住民和欧洲裔澳大利亚人的肥胖及体脂分布与体重指数(BMI)之间的关系。
横断面志愿者样本。
澳大利亚中部和北部偏远地区的原住民社区、居住在澳大利亚墨尔本的城市欧洲裔澳大利亚人。
BMI<30 kg/m²、年龄在18 - 35岁的健康原住民(130名女性,120名男性)和欧洲裔澳大利亚人(100名女性,47名男性);所有女性均未怀孕。
测量人体测量学变量,并使用四端阻抗体积描记法测量电阻抗。
原住民女性和男性比欧洲裔澳大利亚人明显更矮、体重更轻(P<0.05)。与欧洲裔澳大利亚女性相比,原住民女性的腰围和腰臀比(WHR)明显更大(P<0.0005)。与欧洲裔澳大利亚女性相比,原住民的四处皮褶厚度(SFT)总和(S4)及躯干SFT更高(P<0.0005);然而,四肢SFT往往更低(P = 0.06)。另一方面,与欧洲裔澳大利亚男性相比,原住民的BMI明显更低(P = 0.011),臀围也是如此(P = 0.001);然而,WHR明显更高(P = 0.007)。回归分析显示,在相同身高²/电阻(无脂肪量的替代指标)和S4(皮下脂肪的替代指标)情况下,原住民女性和男性比欧洲裔澳大利亚人更重;并且在任何给定的S4和身高²/电阻值下,与欧洲裔澳大利亚男性相比,原住民男性的BMI明显更高(高1.2 kg/m²;P<0.0005)。
对于给定的体重或BMI,澳大利亚原住民和欧洲裔澳大利亚人的体脂分布和脂肪量存在显著差异。使用世界卫生组织推荐的BMI范围来确定澳大利亚原住民的体重状况可能并不合适。
