Summary
Nutritional status may be assessed by measurement of skin-fold thickness with callipers (the area overlying the triceps muscle is often used) or by calculation of the body mass index (BMI). BMI is obtained by dividing weight (kg) by the square of the height (m). Values between 20 and 24 are normal, with > 30 indicating obesity and > 40 severe obesity. BMI is also called Quetelet’s test after Adolphe Quetelet (1796–1874), a Belgian mathematician who came up with the concept of the ‘average’ man.
