NEW CREATININE STANDARD FOR BASAL METABOLISM AND ITS CLINICAL APPLICATION

I. NORMAL CHILDREN: GROUP A  The study reported in this section of the present paper extended and confirmed previous investigations on the relation between creatinine excretion and basal energy metabolism.¹ In a recent publication^1b two of us with F. Broughton presented a creatinine standard of metabolism which was based on a mixed group composed of "hospital normal" patients, normal children and normal adults. Those studies were carried further with the series of subjects reported on here. This group was made up entirely of normal school children and may therefore be considered ideal. Using the newer series alone, we prepared a new creatinine standard by statistical methods.The data were obtained from two groups of children who differed in age and socioeconomic status. The children composing the first group attended a private day school. They were enrolled in a growth study project,² the physical aspects of which were
