目的：比较波利尼西亚和欧洲血统的新西兰人的身体大小和身体成分之间的关系，并建立波利尼西亚人脂肪量的特定回归方程。（93男，96女），185名萨摩亚人（88名男性，97名女性）和241名欧洲人（89名男性，152名女性），年龄20 - 70岁。身高、体重、四种皮褶厚度、生物电阻抗分析（BIA）和双能X线吸收法（DXA）。在较高的身体质量指数水平，波利尼西亚人（毛利人和萨摩亚人合并）有一个显着较高的比例，瘦体重：脂肪质量相比，欧洲人。四个多元回归方程，将电阻和电抗，身高和体重，总和的四个皮褶或总和的两个皮褶，开发了三分之二的波利尼西亚参与者使用DXA脂肪质量作为因变量。在剩下的三分之一的参与者中，这些方程预测的脂肪量（r（2）范围为0.89 - 0.93）和DXA脂肪量之间的平均差异范围为-0.06至+0.25 kg（s.d.）。- 结论：在较高的BMI水平下，波利尼西亚人明显比欧洲人瘦，这意味着需要单独定义波利尼西亚人的超重和肥胖的BMI。使用BIA，身高和体重或皮褶厚度的回归方程是很好的预测波利尼西亚人的身体成分。
OBJECTIVES: To compare the relationship between body size and body composition in New Zealanders of Polynesian and European descent and to develop specific regression equations for fat mass for Polynesians.SUBJECTS: 189 Maori (93 males, 96 females), 185 Samoans (88 males, 97 females) and 241 Europeans (89 males, 152 females) aged 20 - 70 y.MEASUREMENTS: Height, weight, four skinfold thicknesses, bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DXA).RESULTS: At higher body mass index levels, Polynesians (Maori and Samoans combined) had a significantly higher ratio of lean mass:fat mass compared with Europeans. Four multiple regression equations incorporating resistance and reactance, height and weight, sum of four skinfolds or sum of two skinfolds were developed in two-thirds of the Polynesian participants using DXA fat mass as the dependent variable. In the remaining one-third of participants, the mean difference between fat mass predicted by these equations (r(2) range 0.89 - 0.93) and DXA fat mass ranged from - 0.06 to + 0.25 kg (s.d. - 3.67 to + 3.71 kg),CONCLUSION: At higher BMI levels, Polynesians were significantly leaner than Europeans, implying the need for separate BMI definitions of overweight and obesity for Polynesians. The regression equations using BIA, height and weight or skinfold thicknesses were good predictors of body composition in Polynesians.
