About this trial

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
