Urea/creatinine nitrogen levels as indicators of protein intake L Effect of water intake on basal excretion of urea and creatinine in children of different nutritional background
Arch LatinoAmerican Nutr: 203-212
Urea excretion under fasting condition was studied in 3 groups of pre-school age children with different nutritional characteristics, corresponding to "low", "intermediate" and "high" protein intake. The urea excreted was determined under conditions of minimum urinary flow rate, and after water diuresis was provoked. A significant increase in urea excretion was observed associated with the water load, only in the group with low protein intake.
