Intervention(s)

Intervention group:
The pupils in the intervention schools will use a computer-tailored intervention on weight gain related behaviours (physical activity, sedentary behavior, snack, fruit and vegetable, fiber and soft-drink consumption) during their first year of secondary school. The intervention will be used during school hours as part of the education program. The intervention will be used for an average of 2 hours (preferably divided by 8 times 15 minutes) within 10 subsequent weeks.

Control group:
The control group will receive regular school lessons. After two years the intervention will be available for the control group as well.

Waist circumference measured between hipbone and lowest rib, at baseline and 2 year follow-up.

Secondary Outcome(s)

1. Physical activity measured with self-report questionnaires plus pedometer counts (for part of the participants) at baseline, three months and 2 year follow-up;
