By using the stepped-wedge study design, with internal control schools, will enable the control for the seasonal variation in children's physical activity levels and for the age-related decline in physical activity throughout childhood. That is, without control schools we would be unable to attribute a change in physical activity to the reconstruction of the schoolyards - as any difference in physical activity before and after the schoolyard reconstruction in the intervention group could be explained by the natural change in physical activity over time.",[9],null,[21],{"name":22,"affiliation":5,"role":23},"Daniel Berglind, PhD","PRINCIPAL_INVESTIGATOR",[25],{"name":22,"role":26,"phone":27,"phoneExt":19,"email":28},"CONTACT","+46703644797","daniel.berglind@ki.se",[30],{"facility":5,"status":31,"city":32,"state":19,"zip":33,"country":34,"countryCode":35,"cosmosGeoPoint":36,"geoPoint":41,"contacts":42},"RECRUITING","Stockholm","113 65","Sweden","SE",{"type":37,"coordinates":38},"Point",[39,40],18.06871,59.32938,{"lat":40,"lon":39},[43],{"name":44,"role":26,"phone":19,"phoneExt":19,"email":19},"Daniel Berglind, Phd.",{"type":23,"investigatorFullName":46,"investigatorTitle":47,"investigatorAffiliation":5,"oldNameTitle":19,"oldOrganization":19},"Daniel Berglind","Associate Professor",[49,52,54],{"name":50,"class":51},"The City of Stockholm","UNKNOWN",{"name":53,"class":51},"Cancerfonden",{"name":55,"class":51},"Arwidssonstiftelsen","100505776","reconstructing-schoolyards-with-greenery-to-increase-schoolchildrens-physical-activity-and-mitigate-climate-changes-100505776",false,"NCT05865782","Reconstructing Schoolyards With Greenery to Increase Schoolchildren's Physical Activity and Mitigate Climate Changes","Skolgårdsprojketet: Bygga om skolgårdar i Stockholm Med grönska för Att öka Skolbarns Fysisk Aktivitet Och hälsa Samt Mildra klimatförändringarna i städer","Inclusion Criteria:\n\nOn school level:\n\n-School selected for schoolyard reconstruction by the City of Stockholm\n\nOn individual level (schoolchildren):\n\n* Enrolled in participating school\n* 8-13 years old at the time of study start\n* In 2nd or 5th grade\n* Parents signed informed consent\n\nExclusion Criteria:\n\nOn school level:\n\n-School not selected for schoolyard reconstruction by the City of Stockholm\n\nOn individual level (schoolchildren):\n\n* Not enrolled in participating school\n* Outside 8-13 years old age range and\u002For not in 2nd or 5th grade\n* Parents declined informed consent",true,"ALL","8 Years","13 Years",{"count":68,"type":69},3600,"ESTIMATED","INTERVENTIONAL",[72],"NA","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.\n\nThe overarching purpose of the proposed project is to:\n\ni. 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",[75,76,77],"Physical Inactivity","Environmental Exposure","Mental Health Wellness 1","2024-06-17",{"date":80,"type":81},"2024-06-20","ACTUAL",{"date":83,"type":81},"2024-05-22",{"date":85,"type":69},"2027-11-30",{"name":5,"class":6},1]
