Parameters:
(1) total body potassium in mmol (1 mole potassium = 39.0983 grams; 1 mmol = 0.039098 grams)
(2) bone mineral weight in kilograms (determined by dual-energy X-ray absorptiometry as described by Economos et al)
total body protein in kilograms =
= (0.00252 * (total body potassium in mmol)) + (0.732 * (bone mineral weight in kg))
total body protein in kilograms =
= (0.00252 * (total body potassium in mmol)) + 2.00
where:
• Bone mineral density for healthy adult women is 2.62 +/- 0.42 kg.
• Bone mineral density for healthy adult men is 2.85 +/- 0.54 kg
• The first equation is given on page 981 and the second on page 983.
total body protein by in vivo activation in kilograms =
= (0.00240 * (total body potassium in mmol)) + 2.96
where:
• The r = 0.91 and P < 0.001.
