    Skinfold thickness, waist and hip circumference were assessed as an indication of body fat. Skinfold thickness can noninvasively and reliably be measured at various sites of the body using a skinfold caliper. Based on measurements at multiple sites of the body, the total body fat and contribution of fat to the body mass can be estimated.
