Clinical Role of Three-Dimensional Body Scanners in Presenting Direct Anthropometrics for Estimation of Body Composition: Three-Dimensional Body Scanner and Body Composition

Objective: Anthropometric quantities were calculated to evaluate the growth kinetics in children and health-related diseases in adults. Dual-energy x-ray absorptiometry is highly valuable to measure the effectiveness of three-dimensional body image. This study aims to investigate the clinical relevance of the three-dimensional body scanners in providing direct anthropometrics for estimations related to body composition. Methods: In this analytical cross-sectional study, 2 significant groups were recruited through purposive sampling. The first included the calibration group, where 38 participants were recruited based on the age groups between 20 and 60 years. Besides, age, body mass, height, and body mass index calculations were examined by using dual-energy x-ray absorptiometry and three-dimensional scans to provide valuable results. Results: Differences in measurements were observed between the calibration group and the validation group. Linear models were used to predict dual- energy x-ray absorptiometry body composition from three-dimensional scan measurements. High clinical relevance for three- dimensional optical measurements related to height (0.02 m(2)), right arm (0.02m(2)), and left leg (0.05 m(2)) was observed. The highest coefficient variation of 3.46% was achieved for the average left/right arm. The body mass index values were indicated by the mean values of 25.6 kg/m(2) and 24.5 kg/m(2), respectively. Conclusions: The mass of individuals in both groups was provided at the mean values of 80.0 kg and 79.5 kg, respectively. Test-retest measurements showed a strong association for whole body fat, fatfree mass, and arms, legs, and trunk. Three- dimensional body scanners were found effective in clinical settings for treatment procedures.
