Index of subcutaneous fat and hence body fat content. Measured at four sites: biceps (midpoint of front upper arm), triceps (midpoint of back upper arm), subscapular (directly below point of shoulder blade at angle of 45 degrees), supra-iliac (directly above iliac crest in mid-axillary line). Rapid surveys often involve only biceps. See also anthropometry.
