title: Studies on the effect of nutritional deprivation during childhood on body composition of adolescent boys: creatinine excretion.
abstract: Forty-eight hour urinary creatinine excretion was measured in 50 boys aged 14 yr. who had had varying degrees of growth retardation during their preschool years. Subjects with growth retardation continued to be shorter and lighter and also had lower urinary creatinine excretion values per cm height or per kg weight. Creatinine height index values showed a deficit of about 40%. It is not clear whether this reduction in creatinine index represents a reduction in muscle mass or an altered creatine turnover. There is a need to study the body composition pattern among undernourished communities using direct methods.
