Six- and seven-year-olds in West Midlands primary schools will spend a year getting extra physical activity, healthy cooking classes, and a football-club wellness programme, as researchers test whether a community-wide intervention can prevent childhood obesity. Childhood obesity rates in the UK remain high, and effective prevention programmes that work in real-world school settings are scarce. This trial directly tests whether a multi-component approach—combining school-day activity boosts, family cooking sessions, and signposting to local leisure opportunities—can shift the weight distribution of an entire year group, compared to schools that continue usual practice. If the intervention proves effective and cost-effective, it could give local authorities and school leaders a ready-to-use, evidence-based package for obesity prevention. The programme’s partnership with Aston Villa Football Club also suggests a replicable model for leveraging iconic local institutions to engage families. Even if the results are negative, the trial will provide rigorous data on what does not work, saving future public health investment from being wasted on ineffective approaches. The study is applied research with a direct, practical aim: reducing obesity prevalence in primary-age children.

Aim To assess the effectiveness and cost-effectiveness of a community-level, multi-component intervention programme in preventing obesity in 6-7 year old children, compared to usual practice. Design A cluster randomised controlled trial, using schools as units of randomisation and analysis. Setting Local Education Authority maintained primary schools within the West Midlands. Population Children age 6-7 attending primary schools in the West Midlands. Schools will be stratified according to urban vs. rural location, proportion of pupils from ethnic minority groups and proportion of children entitled to free school meals (as a proxy for deprivation). Schools in each stratum will be randomly allocated to intervention or control arms. Intervention A multi-component intervention programme will be delivered to schools in the intervention arm for one year. This programme consists of several elements; activities to increase the time spent doing physical activity within the school day, participation in the ‘Villa Vitality’ programme (a programme that is delivered by an iconic sporting institution (Aston Villa Football Club), which provides interactive learning and opportunities for physical activity and healthy eating), healthy cooking sessions in school time for parents and children, and provision of information to families signposting local leisure opportunities. Outcome measures Primary outcome measure: The difference in percentage of children categorised as normal weight, overweight and obese in control compared to intervention schools. Overweight and obese will be defined by BMI, using cut-offs at the 85th and 95th percentiles on the UK 1990 reference charts for BMI centiles for boys and girls. Secondary outcome measures: As BMI has limitations as a proxy measure for adiposity, other indirect measures of adiposity will be undertaken, including waist circumference, skinfold thickness and bioimpedance analysis. In addition, blood pressure, 24 hour dietary intake and physical activity will be assessed. Health-related quality of life and body image will also be assessed.
