skin fold

, skinfoldA doubling of skin and its underlying adherent subcutaneous tissue. To assess a person's body fat, a skin fold is pinched at a standard site, and the thickness of the doubled skin is measured, using skin fold calipers; a body fat estimate is then calculated using a table or a computer program. There are 6-12 standard locations for measuring skin fold thickness, including over the triceps muscle along the back of the arm and just above the iliac crest of the hip. See also: fold
