The U.S. Army
uses equations developed by Vogel et al for predicting the
percent body fat in adults.
Parameters
(1) gender
(2) body weight in kilograms
(3) height in centimeters
(4) abdomen circumference at the level of the umbilicus in
centimeters (abdomen II)
(5) neck circumference in centimeters below the larynx
(Adam's apple)
(6) wrist circumference in centimeters
(7) forearm circumference in centimeters (arm abducted at
90 to body with hand supinated upwards; measurement taken
at largest part of the forearm)
(8) hip circumference in centimeters at the level of
greatest protrusion of the buttocks
Formulae
(1) male percent body fat = (76.5 * LOG10((abdomen II) -
(neck circumference))) - (68.7 * LOG10(height)) + 46.9
(2) female percent body fat = (105.3 * LOG10(weight)) -
(0.200 * (wrist circumference)) - (0.533 * (neck
circumference)) - (1.574 * (forearm circumference)) +
(0.173 * (hip circumference)) - (0.515 * (height)) - 35.6
