Children and Adolescents' Anthropometrics Body Composition from 3-D Optical Surface Scans

Area of Science:

• Biomedical Engineering
• Pediatric Health
• Body Composition Analysis

Background:

• Accurate anthropometry and body composition are crucial for pediatric health assessment.
• Traditional methods can be time-consuming and invasive.
• Novel technologies are needed for precise and accessible measurements.

Purpose of the Study:

• To evaluate the accuracy and precision of three-dimensional optical (3DO) whole-body scanning.
• To assess 3DO scanning for automated anthropometry and body composition estimation in children and adolescents.

Main Methods:

• 181 healthy children and adolescents (ages 5-17) participated.
• Dual-energy x-ray absorptiometry and 3DO scans were performed.
• Conventional tape measurements served as the criterion standard.

Main Results:

• 3DO estimates showed strong associations with dual-energy x-ray absorptiometry for percent body fat (R²=0.83), fat mass (R²=0.96), and fat-free mass (R²=0.98).
• 3DO provided reliable measurements for fat mass, fat-free mass, and percent body fat with high precision (low coefficients of variation and RMSE).

Conclusions:

• Three-dimensional optical scanning is accurate and precise for anthropometry and body composition in pediatric populations.
• 3DO scanning is a safe, accessible, and practical tool for research and clinical evaluation of body shape and composition.
