InBody Validation Study


About this study

With, one in three Americans now having a body mass index (BMI) greater than 30, and the fastest growing segment of the population having a BMI greater than 40, it is paramount to conduct validation of approaches to measure body composition. Currently the dual-energy x-ray absorptiometry (iDXA) is the gold standard for measuring the body composition. But it is often difficult to perform since it is limited to specific height, weight and BMI's. InBody is a tool which uses bio electric impedance to measure the body composition. This study will compare both approaches. Validation is necessary as it is clinically quite pertinent to accurately assess a patients' body fat percentage, fat free mass, and total body water and changes that are occurring with nutritional support.
