Anthropometric assessment was done with the individuals using light clothes and barefoot, standing up with the feet together (Heyward, 2000). Weight was determined by a digital scale with an accuracy of 100 g and height by a portable stadiometer with an accuracy of 0.1 cm. The body mass index (BMI) was then calculated and the nutritional status of the individual was classified according to the WHO’s criteria (WHO, 1995). Waist circumference (WC) was measured with an inelastic tape measure at the midpoint between the lowest rib and the iliac crest.
