很少有调查评估当前身体成分技术在不同种族和民族人群中的有效性。本研究评估了按种族和民族分层的多种族样本中常见身体成分方法的有效性。招募了 110 名个体（55% 为女性，年龄：26 中心点 5（标准差 6 中心点 9）岁），身份为亚洲人、非裔美国人/黑人、白种人/白人、西班牙裔、多种族和美洲原住民。通过评估总误差 (TE) 和估计值的标准误差，根据四室标准模型对七个身体成分模型（双能 X 射线吸收测定法 (DXA)、排气体积描记法 (ADP)、两个生物电阻抗装置（BIS、IB）和三个多室模型）进行评估。对于总样本，与标准相比，多室模型的脂肪百分比和无脂肪质量 (FFM) 测量结果均非常理想（脂肪百分比：TE = 0 中心点 94-2 中心点 37 %；FFM：TE = 0 中心点 72-1 中心点 78 kg）。 DXA、ADP 和 IB 的脂肪百分比测量值非常好到极好（TE = 2 中心点 52-2 中心点 89%），BIS 则相当好（TE = 4 中心点 12%）。对于 FFM，单设备估计良好（BIS；TE = 3 中心点 12 kg）至理想（DXA、ADP、IB；TE = 1 中心点 21-2 中心点 15 kg）。结果在每个种族和民族之间没有显着差异，但 BIS 对于非裔美国人/黑人、白种人/白人和多种族参与者的脂肪百分比无效（TE = 4 中心点 3-4 中心点 9 %）。评估的多室模型可用于多种族样本以及每个种族和民族，以获得脂肪百分比和 FFM 的高度有效结果。 DXA、ADP 和 IB 的估计也是有效的。 BIS 可能会证明所有种族和族裔群体的 TE 都较高，因此应谨慎解释结果。
Few investigations have evaluated the validity of current body composition technology among racially and ethnically diverse populations. This study assessed the validity of common body composition methods in a multi-ethnic sample stratified by race and ethnicity. One hundred and ten individuals (55 % female, age: 26 center dot 5 (sd 6 center dot 9) years) identifying as Asian, African American/Black, Caucasian/White, Hispanic, Multi-racial and Native American were enrolled. Seven body composition models (dual-energy X-ray absorptiometry (DXA), air displacement plethysmography (ADP), two bioelectrical impedance devices (BIS, IB) and three multi-compartment models) were evaluated against a four-compartment criterion model by assessing total error (TE) and standard error of the estimate. For the total sample, measures of % fat and fat-free mass (FFM) from multi-compartment models were all excellent to ideal (% fat: TE = 0 center dot 94-2 center dot 37 %; FFM: TE = 0 center dot 72-1 center dot 78 kg) compared with the criterion. % fat measures were very good to excellent for DXA, ADP and IB (TE = 2 center dot 52-2 center dot 89 %) and fairly good for BIS (TE = 4 center dot 12 %). For FFM, single device estimates were good (BIS; TE = 3 center dot 12 kg) to ideal (DXA, ADP, IB; TE = 1 center dot 21-2 center dot 15 kg). Results did not vary meaningfully between each race and ethnicity, except BIS was not valid for African American/Black, Caucasian/White and Multi-racial participants for % fat (TE = 4 center dot 3-4 center dot 9 %). The multi-compartment models evaluated can be utilised in a multi-ethnic sample and in each individual race and ethnicity to obtain highly valid results for % fat and FFM. Estimates from DXA, ADP and IB were also valid. The BIS may demonstrate greater TE for all racial and ethnic cohorts and results should be interpreted cautiously.
