Parameters:
(1) gender
(2) body weight in kilograms
(3) height in centimeters
(4) chronological age in years
(5) bone age in years
For normal males:
total body water in liters =
= (0.611 * (body weight)) + 0.251
= (2 * (chronological age)) + 0.76
= (1.877 * (bone age)) + 4.352
= (0.00255 * ((height)^2)) – (0.295 * (height)) + 12.773
= (0.181 * (height)) – 7.524 if height <137.22 cm
= (0.612 * (height)) – 66.662 if height >= 137.22 cm
= (0.397 * (weight)) + (0.067 * (height)) – 2.778 if height < 137.22 cm
= (0.381 * (weight)) + (0.257 * (height)) – 28.985 if height >= 137.22 cm
For normal females:
total body water in liters =
= (0.551 * (body weight)) + 1.244
= (1.7 * (chronological age)) + 2.126
= (1.49 * (bone age)) + 3.363
= (0.00162 * ((height)^2)) – (0.123 * (height)) + 5.487
= (0.141 * (height)) – 4.655 if height <113.02 cm
= (0.337 * (height)) – 26.792 if height >= 113.02 cm
= (0.024 * (weight)) + (0.136 * (height)) – 4.476 if height < 113.02 cm
= (0.320 * (weight)) + (0.135 * (height)) – 9.577 if height >= 113.02 cm
