[Andalies project: consumption, offer and promotion of healthy eating habits within secondary schools in Andalusia].

INTRODUCTION
The school context stands out as one of the factors influencing the food practices of adolescents. Food consumption during the school day, the cafeterias´ supply and the promotional activities proposed by the centers are objects of increasing attention to community health services.

OBJECTIVES
To describe students´ eating habits during the school day; to analyze the food on offer by the cafeterias and surrounding establishments; and to assess whether secondary schools are suitable environments for the promotion of healthy eating habits.

DESIGN AND SAMPLE
Cross-sectional study during 2010-2012 courses. Sampling units: public secondary schools (95) and students (8.068). Multistage cluster sampling: random and stratified selection by province and habitat size. Selection of students: systematic sampling of classrooms.

RESULTS
77.5% of students have breakfast at home: cereals and a dairy product (40.9%) or a liquid (29.2%); 70.3% eat something at school and most of them choose a cold meat sandwich. Fruit consumption is infrequent (2.5%) while packed juices are very common (63.3%). 75% eat sweets, the figure increasing significantly in schools with cafeterias. Cafeterias offer a large number of non-recommended products: soft drinks (97,3%), cold meats (91,8%), sweets and chips (89%). Lack of control of the products on offer is common (68.42%); only 28.4% of the managers know the law. 72.5% of the centers undertake isolated activities for the promotion of healthy eating habits. 71.5% of the centers are surrounded by shops that supply the students.

DISCUSSION
Low protection of students´ food health is evident, resulting from: students´ nutritional deficits, the low quality of the food offered by the cafeterias and the lack of activities to encourage healthy habits. For which reason, educational, health and local administrations must accept shared responsibility on this subject.
