The prevalence of childhood obesity has increased to epidemic proportions in Western Europe and North America. School-based interventions to prevent obesity have shown evidence of a reduction in the odds of obesity and weight, but most studies are from the US. The aims of this thesis are to examine the feasibility of transferring a US school based obesity prevention intervention for 9 to 10 year olds in England and to complete a feasibility study and pilot cluster randomised controlled trial of this intervention. The intervention is called 'Active for life year 5' (AFLY5). Using data from nationally representative surveys I found that obesity was at least 8% higher in US children aged 9-10 than English children. I found it is feasible and acceptable to adapt a US obesity prevention intervention to England. The intervention may lead to improvements in sedentary behaviour, physical activity, active travel to school, and eating healthy portions of fruit/vegetables, snacks and high energy drinks in English children. However, my pilot studies were too small to provide precise estimates that exclude the null. Homeworks engage some parents and may support behaviour change in a proportion of children. A sample size of 1300 children and 52 schools would be required for a full scale trial. A full-scale RCT of the intervention will provide robust evidence of the effectiveness of the intervention to decrease sedentary behaviour, increase physical activity and healthy eating. There are opportunities to integrate the intervention into existing public health initiatives.
