A comparison of body composition measurement techniques

Abstract

The data indicate that ADP and BIA cannot be used interchangeably, although both measurements had good within- and between-day agreement.

Hand‐to‐foot bioelectrical impedance analysis to measure fat mass in healthy children: A comparison with air‐displacement plethysmography

“…Strong Spearman correlation coefficients were found between FM% ADP and FM% BIA , especially in girls, in accordance with previous studies . Similar results were found based on ICC: good exchangeability in girls but inadequate exchangeability in boys.…”

“…FM% BIA did not result in an overall significant difference but overestimated and underestimated FM% in children with lower and higher FM% respectively. Other studies found significant overall differences for FM% BIA : an underestimation using another HtF BIA in adults and an FtF BIA in children and an overestimation in adults using the same HtF as ours …”

“…There are studies in adults that compare HtF BIA with BodPod (e.g. Refs ), but they do not reflect the challenge in paediatric population of continuing chemical maturation of the fat‐free mass …”

“…All these results show that the BIA cannot replace the BodPod. Also, other authors discouraged the exchangeable use of the examined methods . Differences in specific results can be explained by a different BIA device/formula and biological differences in the study populations, for example, age, ethnicity and overweight status.…”

“…There are studies in adults that compare HtF BIA with BodPod (e.g. Refs 15,16 ), but they do not reflect the challenge in paediatric population of continuing chemical maturation of the fat-free mass. 3 Strong Spearman correlation coefficients were found between FM% ADP and FM% BIA , especially in girls, in accordance with previous studies.…”
