Water turnover of healthy children measured by deuterated water elimination

For healthy children up to 15 years of age, no data exist regarding water turnover as directly measured using stable isotope techniques. Water turnover was measured in 171 healthy children (88 girls, 83 boys, age: 6 weeks–15 years) whilst living in their normal environment. Water turnover was calculated from the equilibrium of2H2O concentration reached in the urine 2–3 h after an oral test load of 2 ml2H2O/kg and the subsequent elimination rate …
