Anthropometric measurements of the students; height was 169.3±8.4 cm, weight was 63.7±12.0 kg, and waist circumferences were 75,8±10,3 cm. The frequency of eating away from home of the university students was for breakfast 4.3 ± 1.5 times a week, for lunch 2.6 ± 1.5 times a week, for dinner 2.2 ± 1.4 times a week.
