Anthropometric measurements
POLAND
Body mass and height were measured using a professional medical scale with a stadiometer (WPT 60/150 OW, RADWAG, Radom, Poland; an accuracy of 0.1 cm and 0.1 kg for height and BM). Body composition and total body water were assessed by means of bioelectric impedance, using Bodystat 1500 (Bodystat Inc., Douglas, UK).
