OBJECTIVE
To assess the reliability of bioelectric impedance analysis (BIA) for predicting total body water (TBW) and extracellular water (ECW) in obese children.
METHODS
Comparison of five prediction models based on: (i) body weight (Wt), (ii) the impedance (Z) index (ZI = height2/Z), (iii) the
The water balance in Wistar, Zucker obese and Zucker lean rats, aged 60 days, was measured by determining the amount of water they drank, that contained in the solid food eaten, the water lost through urine and droppings, the net water accrued (estimated from the composition of the body and the
Adequate intake (AI) standards for water in adolescents range between 2.4-3.3 l/day for males and 2.1-2.3 l/day for females, independent of obesity status. Water intakes and excretions of this population are not well documented. The purposes of this study were to assess water turnover, inputs, and
