Determination of Percent Body Fat Using 3D Whole Body Laser Scanning: A Preliminary Investigation

Abstract

The purpose of this study was to investigate the use of 3D whole body laser scanning technology to estimate body fat content. Percent body fat determined from current Army equations using manual and 3D laser scanning methods were compared to each other and to percent body fat obtained from Dual Energy X-ray Absorptiometry (DEXA), used here as a reference method. Manual measurements of body lengths and circumferences, 3D whole body laser scans and DEXA scans were performed on fifty-one men and women age 18-62. Mean percent body fat was not statistically different between the three methods. Correlation coefficients (R) were moderately high with low standard errors (SEE) and Lin's (1989, 2000) concordance analyses revealed moderate to strong measurement agreement between the three methods. This preliminary study demonstrates that the novel application of 3D whole body laser scanning to determine percent body fat is in close agreement with percent body fat determined using both Army manual measurements and DEXA.
