    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.

    The Forward Color Recall task assesses short-term memory in 8 test trials, of which 4 sections are repeated twice. In the task, the child is presented with two circles of colors, and then has to identify the color from a five-color wheel. The test stops if the child fails a trial twice. The total error score can vary between 0 and 8.
