简要总结
By reconstructing schoolyards with greenery, physical activity levels among children can be increased at the population level and also mitigate health and environmental risks resulting from rising climate changes in urban areas.
The overarching purpose of the proposed project is to:
i. increase physical activity levels among school-aged children, independent of socioeconomic factors, and thus affect short- and long-term health outcomes on a population level ii. establish an evidence-based bottom-up approach for schoolyard reconstructions iii. evaluate the cost-effectiveness of schoolyard reconstructions with greening on health outcomes and its environmental impact
详细描述
Background More than half of Swedish schoolchildren do not meet the physical activity guidelines, which will have long-lasting effects on their health in adulthood. The school environment plays a crucial role in establishing healthy physical activity behaviors for a population.
A formal decision has been made to reconstruct 15 Stockholm public schoolyards from 2024 to 2026. This project is evaluating the effects of this decision.
Project design The project is designed as a quasi-experimental stepped-wedge trial, with schools serving as both intervention and control schools. Over the course of 3 years (2023-2026), a total of 15 schoolyard reconstructions will be evaluated, with 5 reconstructions per year. The units of observation will be second and fifth grade children, totaling 2,700 children.
Methods for data collection The following primary and secondary outcomes will be measured at baseline (May) and at follow-up one year later (May the following year), in all schools, among participating children.
