Accurate assessment of body composition (BC) is important to investigate the development of childhood obesity. A bioelectrical impedance analysis (BIA) device is portable and inexpensive compared with air displacement plethysmography (ADP) for the assessment of BC and is widely used in children. However, studies of the effectiveness of BIA are few and present different results, especially in pediatric populations. The aim of this study was to evaluate the agreement between BIA and ADP for estimating BC.
The BC of 981 Chinese children (3-5 years) was measured using the BIA device (SeeHigher BAS-H, China) and ADP (BOD POD).
Our results showed that BIA underestimated fat mass (FM) and overestimated fat-free mass (FFM) in normal weight children ( < 0.05), but the opposite trend was shown in children with obesity ( < 0.05). The agreement between FM and FFM measured by the two methods was strong (CCC > 0.80). The linear regression equation of 5-year-old children was constructed.
The SeeHigher BAS-H multi-frequency BIA device is a valid device to evaluate BC in Chinese preschool children compared with ADP (BOD POD), especially in 5-year-old children or children with obesity. Further research is needed to standardize the assessment of BC in children.
准确评估人体成分（BC）对于研究儿童肥胖的发展非常重要。与空气置换体描记法（ADP）相比，生物电阻抗分析（BIA）设备用于评估 BC 时便携且价格低廉，因此在儿童中广泛使用。然而，关于 BIA 的有效性的研究很少，且结果不同，尤其是在儿科人群中。本研究旨在评估 BIA 与 ADP 估计 BC 的一致性。
本研究使用 BIA 设备（中国 SeeHigher BAS-H）和 ADP（BOD POD）测量了 981 名中国儿童（3-5 岁）的 BC。
我们的结果表明，在正常体重儿童中，BIA 低估了脂肪量（FM）并高估了去脂体重（FFM）（<0.05），但在肥胖儿童中则表现出相反的趋势（<0.05）。两种方法测量的 FM 和 FFM 之间的一致性很强（CCC > 0.80）。构建了 5 岁儿童的线性回归方程。
与 ADP（BOD POD）相比，SeeHigher BAS-H 多频 BIA 设备是评估中国学龄前儿童 BC 的有效设备，尤其是在 5 岁或肥胖儿童中。需要进一步的研究来规范儿童 BC 的评估。
