All session notes were compared and controlled by recorded files for identifying the main themes to be encoded, classified and analyzed. More than half of the students ate snacks to reduce lack of energy and satisfy hunger. About 50% of girls took cake, waffle and milk while some boys ate fruits, sandwich and cake.

More than half of them stated that the snacks and foods in buffets were invariable, expensive, unhealthy and nonnutritive. With respect to undesirable snack patterns of students, improving the condition of school buffets to have more nutritious foods is a significant step in altering eating habits of them
