School-based physical activity interventions are considered ideal given their potential to reach most children. They can help children achieve the recommended guidelines of 60 minutes of moderate-to-vigorous physical activity per day. The Daily Mile is a popular school-based active mile intervention with a global reach. It recommends ten core principles for successful implementation, three of which are key for effectiveness: that it is quick (15 minutes), the whole school participates, and that it takes place in the school day during lessons (excluding physical education lessons and scheduled breaks). Studies assessing the impacts of The Daily Mile do not often report implementation of the ten core principles which is crucial to identifying the potential impact and feasibility of scalable interventions in real-world settings. Our aim was to assess adherence to The Daily Mile's ten core principles in Greater London primary schools. We created and distributed a survey to 1717 primary schools during September 2020 and achieved a 21% (n = 369/1717) response rate by September 2021. Our sample was representative of Greater London primary schools with responses from every London borough. A total of 196/369 (53%) schools reported implementing The Daily Mile but none of them reported adherence to all ten core principles. Adherence to at least 6/10 principles in various combinations was reported by 54/196 (28%) schools. Only 19/196 (10%) schools that reported implementing The Daily Mile reported adherence to the three key principles recommended for effectiveness. Despite its popularity and global reach, our findings suggest that an implementation gap exists when The Daily Mile is adopted in real-world settings which is likely to challenge its intended purpose. Further research in school settings is needed to understand factors that can improve adherence to increase the potential public health impact of The Daily Mile and other similar interventions.
基于学校的身体活动干预措施被认为是理想的，因为它们有可能接触到大多数儿童。这些干预措施可以帮助儿童达到每天 60 分钟中等到剧烈身体活动的推荐指南。“每日一英里”是一种流行的基于学校的积极一英里干预措施，在全球范围内都有涉及。它为成功实施推荐了十个核心原则，其中三个原则对于有效性至关重要：快速（15 分钟）、全校参与以及在学校日的课程期间进行（不包括体育课和规定的休息时间）。评估“每日一英里”影响的研究并不经常报告十个核心原则的实施情况，这对于确定在现实环境中具有可扩展性的干预措施的潜在影响和可行性至关重要。我们的目的是评估大伦敦地区小学对“每日一英里”十个核心原则的遵守情况。我们在 2020 年 9 月向 1717 所小学创建并分发了一份调查，并在 2021 年 9 月达到了 21%（n=369/1717）的回应率。我们的样本具有代表性，涵盖了大伦敦地区的所有小学，每个伦敦行政区都有回应。共有 196/369（53%）所学校报告实施了“每日一英里”，但没有一所学校报告完全遵守所有十个核心原则。54/196（28%）所学校报告了遵守至少 6/10 个原则的各种组合。只有 19/196（10%）报告实施了“每日一英里”的学校报告遵守了建议的三个关键原则。尽管“每日一英里”很受欢迎且在全球范围内有涉及，但我们的研究结果表明，在现实环境中采用该措施时存在实施差距，这可能会对其预期目的构成挑战。需要在学校环境中进行进一步研究，以了解可以提高遵守率的因素，从而增加“每日一英里”和其他类似干预措施的公共卫生影响。
