a Adolescents at health risk are those who are both at metabolic risk (estimated through the waist circumference percentiles) and alcoholic risk (i.e., drinking 12 g or more of ethanol per day). Health risk is referred to the possibility of developing chronic diseases, such as cardiovascular, alcohol-related, and other metabolic diseases. b Parents’ middle school or lower education was defined by the presence of at least one parent with middle school or lower education. c Non sedentary activities: getting ready in the morning, walking or biking to school or back from school, practising physical activity at school, doing home-based physical jobs (cleaning, hovering, cooking, etc.), outdoor activities or walking during free time, and practising sport. d Meals’ adequacy consisted of the presence of at least 3 adequate main daily meals. A proper meal excluded carbonated and sugar-sweetened drinks or “junk food” for breakfast or morning and afternoon breaks; and a proper meal including a first or a second course with vegetables, fruit, bread, and excluding carbonated and sugar-sweetened drinks or junk food, for lunch and dinner. e Food habits were derived by summing up eating out, eating ready meals, eating organic food, eating fresh food, and eating food from vending machines. They were considered “correct” if subjects had at least 4 correct behaviours among those.
