School-based active mile initiatives such as The Daily Mile™ are widely promoted to address shortfalls in meeting physical activity recommendations. The iMprOVE study aims to examine the impact of The Daily Mile on children’s physical and mental health and educational attainment throughout primary school.
Methods and analysis iMprOVE is a longitudinal quasi-experimental cohort study. We will send a survey to all state-funded primary schools in Greater London to identify participation in The Daily Mile. The survey responses will be used for non-random allocation to either the intervention group (Daily Mile schools), or to the control group (non-Daily Mile schools). We aim to recruit 3,533 Year 1 children (aged 5-6 years) from 77 primary schools and follow them up annually until the end of their primary school years. Data collection taking place at baseline (children in school Year 1) and each primary school year thereafter, includes device based measures of moderate to vigorous physical activity (MVPA), and questionnaires to measure mental health (Strengths and Difficulties Questionnaire), and educational attainment (ratings from ‘below expected’ to ‘above expected levels’). The primary outcome is the mean change in MVPA minutes from baseline to Year 6 during the school day among the intervention group compared with controls. We will use multilevel linear regression models adjusting for socio-demographic data and participation in The Daily Mile. The study is powered to detect a 10% (5.5 minute) difference between the intervention and control group which would be considered clinically significant.
Ethics and dissemination Ethics has been approved from Imperial College Research Ethics Committee, reference 20IC6127. Key findings will be disseminated to the public through research networks, social, print and media broadcasts, community engagement opportunities and schools. We will work with policy makers for direct application and impact of our findings.
