An accurate estimation of Resting Energy Expenditure (REE) in patients with obesity is crucial. Therefore, our aim was to assess the validity of REE predictive equations based on body composition variables in treatment-seeking Arab adults with obesity.
Body composition and REE were measured by Tanita BC-418 bioimpedance and Vmax Encore 229 IC, respectively, and predictive equations based on fat mass and fat-free mass were used in REE estimations among 87 adults of both genders, in the Outpatient Clinic in the Department of Nutrition and Dietetics at Beirut Arab University (Lebanon). The mean differences between the measured and estimated REE values were calculated to assess the accuracy, and the Bland-Altman method was used to assess the level of agreement.
Ten predictive equations were included. In males, all the predictive equations gave significantly different estimates of REE when compared to that measured by IC. On the other hand, in females, the mean difference between the REE value estimated by Huang and Horie-Waitzberg equations and that measured using IC was not significant, and the agreement was confirmed using Bland-Altman plots.
Huang and Horie-Waitzberg equations are suggested for accurate REE estimation in females; however, new validated REE estimation equations for males in this population are still needed.
准确估算肥胖患者的静息能量消耗（REE）至关重要。因此，我们的目的是评估基于身体成分变量的REE预测方程在寻求治疗的肥胖阿拉伯成年患者中的有效性。
分别采用Tanita BC - 418生物阻抗分析仪和Vmax Encore 229 IC测量身体成分和REE，并在黎巴嫩贝鲁特阿拉伯大学营养与饮食学系门诊对87名成年男女使用基于脂肪量和去脂体重的预测方程进行REE估算。计算测量值与估算值之间的平均差异以评估准确性，并采用Bland - Altman方法评估一致性水平。
纳入了10个预测方程。在男性中，与IC测量值相比，所有预测方程得出的REE估算值均有显著差异。另一方面，在女性中，Huang方程和Horie - Waitzberg方程估算的REE值与IC测量值之间的平均差异不显著，并通过Bland - Altman图证实了一致性。
建议使用Huang方程和Horie - Waitzberg方程准确估算女性的REE；然而，该人群中仍需要针对男性的新的经过验证的REE估算方程。
