Developing Size Specifications of 3D Body Models for Males Aged between 7 and 18

This study aims to set the size ranges for male human body aged between 7 and 18, and to develop detailed body measurement criteria for each size. For that purpose, total 31 items were selected from the references of 5th SizeKorea Survey to carry out a statistical analysis, and they included 11 items for height, 15 for circumference and 15 items for length. Through the factorial analysis of those 31 items for body measurement, two dominant factors of obesity and height could be extracted as representative elements for body types. The circumference of waist was designated as the representative element for obesity factor, and the height as the representative element for height factor, and the size ranges were set to 3cm and 5cm intervals each for waste circumference and height. With two age groups of 7-12 and 13-18, the waste circumference and the height were cross-analyzed to decide high frequency sections, and based on this, the size ranges for 3D model development were decided. Lastly, detailed measurement specifications according to size ranges were developed through regression analysis. In this regression analysis, the circumference of waist was put as independent variable and the height as dependent variable. As a result, it was proved in this study that the circumference of waste was a strong element to explain obesity factor, and the height was to explain height factor in body measurement, and size specifications were developed according to different size ranges.
