Scalability and scaling-up strategy of a physical activity policy intervention in Australian childcare centres
There is an urgent need for scalable interventions to promote physical activity in early childhood. An early childhood education and care (ECEC) physical activity policy intervention with implementation support strategies (Play Active) has been proposed for scale-up in Australia. This study sought to assess the scalability of Play Active and describe the Play Active scaling-up strategy. The Intervention Scalability Assessment Tool was used to ass…
Associations between natural blue and green space and preschool children's movement behaviours
Natural outdoor environments provide important settings for children to engage in physical activity. It is unclear if these relationships also exist in preschool aged children. We examined associations between amount and type of neighbourhood vegetation and blue space, proximity to the beach and preschooler's device‐measured movement behaviours. Accelerometer data from 1081 preschool children were processed into physical activity and sedentary be…
