The percent body fat in moderately and severely mentally retarded adult males can be estimated with a regression equation using 4 body measurements.
Subjects: 170 adult males from 18 to 40 with moderate-to-severe mental retardation
Parameters:
(1) body weigh in kilograms
(2) height in centimeters
(3) forearm circumference in centimeters
(4) waist circumference in centimeters
percent body fat =
= (0.077 * (body weight in kilograms)) - (0.155 * (height in centimeters)) - (0.527 * (forearm circumference in centimeters)) + (0.487 * (waist circumference in centimeters)) + 13.545
