Abstract
A method will be described of measuring body volume which depends on placing a baby for a few seconds in a closed perspex box and injecting a known quantity of air into the box. The pressure change enables one to calculate the volume change in. the air of the box and thus the baby's volume. This principle is well known but is too insensitive for accurate results. Accurate determination has been made possible by employing a second box of identical dimensions, a differential pressure transducer between the two, and cyclical pressure changes to eliminate artefact caused by the baby's breathing and moving. Total body fat measurements in small for dates, and in preterm babies are given.
