Assessment of Central Obesity and Body Mass Index in Youth Using a Non-Contact Radar Sensor

Choi Jinjoo , Choe Yunsoo , Yang Seung

Background: Central obesity in children is a significant risk factor for cardiovascular diseases, potentially more critical than BMI-defined obesity, and can persist into adolescence and adulthood. Measuring the Waist-to-Hip Ratio (WHR), an indicator of central obesity and associated health risks, typically requires direct measurement with a tape, which can be inconvenient and socially unacceptable. Therefore, non-contact anthropometric techniques to measure b...
