Primary Outcome Measures

Name	Time	Method
Physical activity in terms of number of steps per day, and minutes of Moderate to Vigorous Activity (MVPA) at various times of the day. Measured using Actigraph GT3X accelerometers.[Baseline, 12 months and 24 months.];Excessive weight gain in terms of body mass index (BMI) z-score and waist circumference. BMI will be calculated as weight in kilograms divided by height in metres squared. BMI will then be converted to z-scores using age- and sex-specific CDC reference data.[Baseline, 12 months and 24 months.]

Secondary Outcome Measures

Name	Time	Method
Perceived bullying assessed using a peer-relations package (PRAQ-R) for use with students, parents and teachers.[Baseline, 12 months and 24 months.];Nutrition assessed by a modified version of the Children's Dietary Questionnaire administered to parents.[Baseline, 12 months and 24 months.];Forms of play that best promote activity. Assessed using the same playworker's evaluations of each school's play area and rating it according to a set schedule resulting an overall score for the whole school play environment. Additional assessment of this secondary outcome via small group interviews with students at the school. Both will be used in conjunction with accelerometery data.[Baseline, 12 months and 24 months.]
