Design outcomes

Primary

MeasureTime frame
Current primary outcome meaures: The difference in BMI z-scores (standardised deviation scores) between control and intervention schools at the first follow up, taking into account clustering, baseline levels and other relevant co-variates. Previous primary outcome measures: 1. The difference in BMI z-scores (standardised deviation scores) between control and intervention schools at the first follow up, taking into account clustering, baseline levels and other relevant co-variates. 2. Comparing the percentage of children categorised as overweight and obese in control compared to intervention schools.

Secondary

MeasureTime frame
Current secondary outcome measures as of 01/11/2017: Secondary outcomes are either binary (e.g. physically active vs. inactive), or continuous (e.g. energy expenditure), and therefore either logistic or linear link functions will be used, with transformations where appropriate to accommodate any non-normality. All model assumptions will be checked, goodness of fit explored and models selected using step wise procedures and analysis of deviance. Anthropometric measures (including percentage of overweight and obesity as defined by the WHO 2007 Growth Charts, waist circumference and body fatness). 1. Dietary Assessment: Parents questionnaire and child diary, where several self designed and adapted validated (University of Leeds SFFQ; Day in Life Questionnaire) questionnaires are included. 2. Physical Activity Assessment: Through parents questionnaire, child questionnaire and child diary, self designed questions and adapt validated (Godin Leisure-Time Exercise Questionnaire; Day in Life Questionnaire and PAQ-C) tools will be used to measure physical activity and sedentary behaviours of participating children. Additionally, a validated objective method (GENEActiv Original) will be used to assess physical activity and sedentary behaviours of the children. 3. Process Evaluation: To understand intervention fidelity as well as participants and facilitators’ barriers and facilitators. These will include focus groups and personal interviews with representatives of participants and programme facilitators. Programme facilitators will also be asked to complete a log book on participant attendance, withdrawals, and note any changes or adaptations that they had to make to any sessions, and known reasons. 4. Economic Evaluation: Comparisons will be made between the situation of supplying the intervention package and a situation where no intervention is in existence (i.e. usual current practice). The pr
