Methods for measuring body composition in newborns--a comparative analysis.
The complexity of nutritional support in infants now makes it necessary to use body-composition methods for accurate nutritional assessment. For this goal a variety of methods of determining body composition have been introduced in research on human nutrition. The purpose of this paper is to review the background and to describe the precision of established techniques, focusing on the results obtained in newborns and infants. The ideal method for assessing newborns' and infants' body composition should be non-invasive, reproducible, accurate, and also relatively inexpensive. In addition, we summarize in this paper data on body composition obtained in normal and pathological newborns by using dual X-ray absorptiometry, one of the reference techniques.
