Air Displacement Plethysmography

Abstract

Differences in body composition are associated with increased disease risk in various stages of life. Despite numerous available methods in assessing body composition (air displacement plethysmography, dual-energy X-ray absorptiometry, bioelectrical impedance, hydrometry, and magnetic resonance imaging), due to innate technical limitations, the ability for one singular method to track body composition over the life span (ie, infancy to adulthood) is challenging and imperfect. 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. 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.

The effect of maternal DHA supplementation on body fat mass in children at 7 years: follow-up of the DOMInO randomized controlled trial

“…This study has a number of strengths. A major strength is the assessment of body composition using two different methods, including the BOD POD method that has been favourably compared with criterion methods, including DXA, in pediatric populations [22].…”

“…However, fat mass in this study was assessed by Bioelectrical Impedance Spectroscopy (BIS), which is not the preferred method of assessment of body composition in children. Air Displacement Plethysmography (ADP), assessed using the BOD POD system, however, has been shown to compare favourably to criterion methods and is rapidly becoming the method of choice for assessment of body composition in paediatric populations [19][20][21][22].…”

Feasibility of Studying Body Composition in Order to Assess and Monitor the Nutritional Status in Children with Congenital Dystrophic Epidermolysis Bullosa

“…Методы оценки состава тела применяются как в научных исследованиях, так и в клинической нутрициологии для более точной и целенаправленной организации нутритивной поддержки различным категориям больных, а также с целью коррекции питания у здоровых лиц. И воздушная бодиплетизмография [7,8,14], и биоимпедансометрия [15][16][17] рекомендованы к использованию в клинической практике. Известно, что дистрофические формы врожденного буллезного эпидермолиза в большинстве случаев сопровождаются тяжелой нутритивной недостаточностью [1][2][3], что показало и наше исследование.…”

Noninvasive assessment of autonomic function in human neonates born at the extremes of fetal growth spectrum

“…Air‐displacement plethysmography is an age‐appropriate method for assessing body composition (Fields et al. ), and has been validated in both term and preterm infants (Ma et al. ; Ellis et al.…”

“…Body composition was measured in infants in the first 24 h of life with air-displacement plethysmography (PEA POD â , COSMED USA, Inc), as part of routine clinical practice. Air-displacement plethysmography is an age-appropriate method for assessing body composition (Fields et al 2015), and has been validated in both term and preterm infants (Ma et al 2004;Ellis et al 2007;Roggero et al 2012). This technique accurately measures body volume by the application of Boyle's law to the displacement of air by the infants in a sealed chamber.…”
