Air Displacement Plethysmography: Cradle to Grave

Posted in Body Composition, Scientific

indirect calorimetry

A new scientific review paper, published in ASPEN Nutrition in Clinical Practice Journal, tries to find a singular body composition tool that is valid, reliable, precise, and easy to administer across the life span

The primary goal of this review is to determine if there are body composition methods that can accurately track body composition from infancy into adulthood. The review, undertaken by David A. Fields and team at the Department of Pediatrics, Section of Endocrinology and Diabetes, University of Oklahoma Health Sciences Center, analyzes Air Displacement Plethysmography technology and performs a side-by-side comparison of the 3 plethysmography techniques available from COSMED (ie, Pea Pod, Bod Pod, and Bod Pod with Pediatric Option).

The conclusions are that, "after careful consideration and taking into account the best available scientific evidence, we feel air displacement plethysmography is the best instrument at this time for tracking body composition, starting in infancy and forward into adulthood, partly because it is the only “practical” clinical tool currently available for use during infancy."
