Total body water model: F = 85.7, p < 0.00; Fat mass and bone mineral content were not significant predictors in this model. Intracellular water model: F = 18.9, p < 0.00; Bone mineral content was not a significant predictor in this model. Extracellular water model: F = 150.6, p < 0.00; Fat mass and bone mineral content were not significant predictors in this model.
