Intervention(s)

Intervention group:
The pupils in the intervention schools will use a computer-tailored intervention on weight gain related behaviours (physical activity, sedentary behaviour, snack, fruit and vegetable, fibre 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 two hours (preferably divided by eight times 15 minutes) within ten 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.

Primary Outcome(s)

1. BMI calculated from measured height and weight, at baseline and two year follow-up
2. Waist circumference measured between hip bone and lowest rib, at baseline and two 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 two year follow-up
2. Physical condition measured with a shuttle-run-test at baseline and two year follow-up
3. Various dietary sub-behaviours, i.e. fruit and vegetable consumption, soft-drink consumption, snack consumption and fibre consumption measured with self-report questionnaires at baseline, three months and two year follow-up
4. Amount of television viewing/time spend with the computer measured with self-report questionnaires at baseline, three month and two year follow-up
5. Awareness of personal bodyweight status, overweight-related risk perceptions, weight maintenance attitudes, perceived behavioural control, and motivation to engage in weight maintenance behaviours, measured with self-report questionnaires at baseline, three months and two year follow-up
6. Determinants of change for the separate dietary, physical activity and sedentary behaviours, as measured by self-report questionnaires, distributed at baseline, three months and two year follow-up
