目的：低和高体重指数（BMI）值已被证明会增加健康风险和死亡率，并导致无脂肪质量（FFM）和体脂质量（BF）的变化。目前，无脂肪质量指数（FFMI; kg/m2）、体脂质量指数（BFMI; kg/m2）和体脂百分比（%BF）的范围尚未公布。这项人口研究的目的是确定预测FFMI和BFMI值低，正常，超重和肥胖的BMI.METHODS：FFM和BF确定在2986健康的白色男性和2649白色女性，年龄15至98岁，由先前验证的50 kHz生物电阻抗分析方程。结果：在正常BMI范围内，男性FFMI值为16.7至19.8 kg/m2，女性为14.6至16.8 kg/m2。在正常BMI范围内，男性的BFMI值为1.8至5.2 kg/m2，女性为3.9至8.2 kg/m2。对于肥胖BMI（>30 kg/m2），男性和女性的BFMI值分别为8.3和11.8 kg/m2。%BF的正常范围分别为13.4至21.7和24.6至33.2，男性和女性，分别为CONCLUSION：BMI单独不能提供有关各自的贡献FFM或脂肪量体重的信息。本研究提供了对应于低、正常、超重和肥胖BMI的FFMI和BFMI值。FFMI和BFMI提供了有关身体隔室的信息，与身高无关。
OBJECTIVE: Low and high body mass index (BMI) values have been shown to increase health risks and mortality and result in variations in fat-free mass (FFM) and body fat mass (BF). Currently, there are no published ranges for a fat-free mass index (FFMI; kg/m(2)), a body fat mass index (BFMI; kg/m(2)), and percentage of body fat (%BF). The purpose of this population study was to determine predicted FFMI and BFMI values in subjects with low, normal, overweight, and obese BMI.METHODS: FFM and BF were determined in 2986 healthy white men and 2649 white women, age 15 to 98 y, by a previously validated 50-kHz bioelectrical impedance analysis equation. FFMI, BFMI, and %BF were calculated.RESULTS: FFMI values were 16.7 to 19.8 kg/m(2) for men and 14.6 to 16.8 kg/m(2) for women within the normal BMI ranges. BFMI values were 1.8 to 5.2 kg/m(2) for men and 3.9 to 8.2 kg/m(2) for women within the normal BMI ranges. BFMI values were 8.3 and 11.8 kg/m(2) in men and women, respectively, for obese BMI (>30 kg/m(2)). Normal ranges for %BF were 13.4 to 21.7 and 24.6 to 33.2 for men and women, respectively.CONCLUSION: BMI alone cannot provide information about the respective contribution of FFM or fat mass to body weight. This study presents FFMI and BFMI values that correspond to low, normal, overweight, and obese BMIs. FFMI and BFMI provide information about body compartments, regardless of height.
