The CHANGE! pilot study is a clustered randomised controlled trial (RCT) investigating the efficacy of a twenty lesson school-based physical activity and healthy eating intervention. CHANGE! is delivered through the Personal and Social Health Education strand of schools curricula and the curriculum resource is supplemented by homework tasks that target family involvement.
Twelve schools from the Wigan Borough in North-West England were recruited to the study, Six randomly assigned using a random number generator to the intervention condition. Randomisation occurred prior to baseline measures. Class teachers from the intervention schools received training in the curriculum resource over two twilight training sessions, and were fully familiarised with the CHANGE! curriculum prior to implementation. CHANGE! consists of 20 lesson plans, including worksheets and other resources. This curriculum resource is supplemented by homework tasks that target family involvement. Control schools will receive the curriculum and training in the following academic year once the study has been completed. Measures were completed for intervention and control groups at baseline and will be repeated post-intervention (20 weeks) and at 30-32 weeks follow up, prior to the school summer holidays.
Primary outcome measure
Levels of habitual physical activity, moderate to vigorous physical activity (MVPA)-outcome measured at baseline and will be repeated post-intervention (20 weeks) and at 30-32 weeks follow up, prior to the school summer holidays.
Secondary outcome measures
1. Anthropometrics and body composition
2. Cardiorespiratory fitness
3. Food intake
4. Eating behaviour and knowledge
5. Physical self-perceptions
6. Family nutrition and physical activity
7. Behaviour change
8. Quality of life
9. Cardiometabolic disease risk markers
10. Fundamental movement skills
Outcomes were measured at baseline and will be repeated post-intervention (20 weeks) and at 30-32 weeks follow up, prior to the school summer holidays.
To reduce ionising radiation dosage, DEXA body composition scans will be conducted at baseline and follow-up only.
