There is no gold standard in body composition measurement in pediatric patients with obesity. Therefore, the aim of this study was to investigate if there are any differences between two bioelectrical impedance analysis techniques performed in children and adolescents with obesity.
Data were collected at the Department of Pediatrics and Adolescent Medicine in Vienna from September 2015 to May 2017. Body composition measurement was performed with TANITA scale and BIA-BIACORPUS.
In total, 38 children and adolescents (age: 10-18 years, BMI: 25-54 kg/m) were included. Boys had significantly increased fat free mass (TANITA p = 0.019, BIA p = 0.003), total body water (TANITA p = 0.020, BIA p = 0.005), and basal metabolic rate (TANITA p = 0.002, BIA p = 0.029). Girls had significantly increased body fat percentage with BIA (BIA p = 0.001). No significant gender differences of core abdominal area have been determined. TANITA overestimated body fat percentage (p < 0.001), fat mass (p = 0.002), and basal metabolic rate (p < 0.001) compared to BIA. TANITA underestimated fat free mass (p = 0.002) in comparison to BIA. The Bland Altman plot demonstrated a low agreement between the body composition methods.
Low agreement between TANITA scale and BIA-BIACORPUS has been observed. Body composition measurement should always be performed by the same devices to obtain comparable results. At clinical routine due to its feasibility, safety, and efficiency, bioelectrical impedance analysis is appropriate for obese pediatric patients.

在肥胖的儿科患者中，体成分测量没有金标准。因此，本研究的目的是探讨两种生物电阻抗分析技术在肥胖儿童和青少年中的应用是否存在差异。
数据于 2015 年 9 月至 2017 年 5 月在维也纳儿科和青少年医学系收集。体成分测量采用 TANITA 秤和 BIA-BIACORPUS 进行。
共纳入 38 名儿童和青少年（年龄：10-18 岁，BMI：25-54kg/m）。男孩的去脂体重（TANITA：p=0.019，BIA：p=0.003）、总体水（TANITA：p=0.020，BIA：p=0.005）和基础代谢率（TANITA：p=0.002，BIA：p=0.029）均显著增加。女孩的 BIA 体脂百分比显著增加（BIA：p=0.001）。核心腹部面积没有显著的性别差异。TANITA 高估了体脂百分比（p<0.001）、脂肪量（p=0.002）和基础代谢率（p<0.001），而 BIA 则低估了去脂体重（p=0.002）。Bland-Altman 图显示两种体成分方法之间的一致性较低。
TANITA 秤和 BIA-BIACORPUS 之间的一致性较低。为了获得可比的结果，体成分测量应始终使用相同的设备进行。在临床实践中，由于其可行性、安全性和效率，生物电阻抗分析适用于肥胖的儿科患者。
