客观化 评估波利尼西亚人和高加索人之间身体成分的差异。 科目 来自库克群岛拉罗通加一个村庄的48名男性和80名女性波利尼西亚人(回复率为81%)和来自澳大利亚墨尔本的243名男性和250名女性高加索人的代表性样本。 测量 体重指数，由生物电阻抗得出的阻力，使用阻力、体重、身高、年龄和性别得出的4个方程式得出的体脂百分比。 结果 男性和女性波利尼西亚人比高加索人年轻(7.7年，P&lt；0.001和4.10岁，P&lt；0.05)，体重(10.7Kg和12.5Kg，P&lt；0.0001)。在波利尼西亚人中，男女的电阻都显著降低了130omega(P&lt；0.0001)。在每个体重水平上(根据身高和年龄进行调整)，波利尼西亚人的抵抗力较低(P&lt；0.0001)，而在身体质量指数的每个水平上，从4个不同方程预测的身体脂肪在波利尼西亚人中较低(P&lt；0.0001)。 结论 这些结果表明，在任何给定的体型下。波利尼西亚人比高加索人瘦得多，需要制定具体的波利尼西亚标准来定义肥胖。这一发现需要通过其他测量身体成分的参考方法来证实。
OBJECTIVE To assess differences in body composition between Polynesians and Caucasians subjects. SUBJECTS 48 male and 80 female Polynesians from a village in Rarotonga, Cook islands (81% response rate) and representative sample of 243 male and 250 female Caucasians from Melbourne, Australia. MEASUREMENTS Body mass index, resistance from bioelectrical impedance, percent body fat derived from 4 equations using resistance, weight, height, age and sex. RESULTS Male and female Polynesians were younger (by 7.7 years, P < 0.001 and 4.1 years, P < 0.05) and heavier (by 10.7 kg and 12.5 kg, P < 0.0001) than their Caucasian counterparts. Electrical resistance was significantly lower in Polynesians of both sexes by over 130 omega (P < 0.0001). At every level of weight (adjusted for height and age), resistance was lower in the Polynesians (P < 0.0001) and at every level of body mass index, the predicted body fat from 4 different equations was lower in Polynesians (P < 0.0001). CONCLUSIONS These results imply that, at any given body size. Polynesians are significantly leaner than Caucasians and that specific Polynesian standards for defining obesity need to be developed. The findings will need to be confirmed by other reference methods for measuring body composition.
