Body water estimates in intrauterine-growth-retarded versus normally grown baboon neonates

Body water content and distribution were compared in 6 intrauterine-growth-retarded and 10 normally grown term baboon neonates. Growth-retarded baboons had larger mean antipyrine and corrected bromide spaces than their normally grown peers. Other water compartments were on the average similar in both groups. This pattern of comparisons is identical to that observed between normally grown and growth-retarded human neonates. Mean estimates for the various body water volumes were strikingly similar for growth-retarded neonates in baboons and humans.
