Weight was measured to the nearest 1 g using a standard beam scale (Seca GmbH & Co KG, Hamburg, Germany). Height was measured using a wall-mounted stadiometer to the nearest 0.1 cm. Waist circumference (WC) was measured at the midpoint between the last rib and the iliac crest on the midaxillary line. Bioelectrical impedance analysis (BIA) was undertaken by a single frequency (50 kHz) tetrapolar device (RJL 101; Akern SRL, Florence, Italy). BIA was performed with a single-frequency measurement. FM and FFM were obtained from measures of resistance and reactance using the algorithm provided by the manufacturer.
