    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.

    Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps blood around the body. Systolic pressure is the pressure when the heart contracts and pushes blood out and diastolic pressure is the pressure when the heart relaxes and fills with blood. In adults, the systolic pressure normally ranges between 80 and 120 and the...
