Physical activity is essential for children’s healthy development, yet COVID-19 physical distancing restrictions such as school closures and staying at home, playground closures, and the cancelling of organised community sport have dramatically altered children’s opportunities to be physically active. This study describes changes in levels of physical activity and screen time from February 2020 (i.e., before COVID-19 restrictions were introduced in Western Australia) to May 2020 (i.e., when COVID-19 restrictions were in place). Parents of children aged 5 to 9 years from Western Australia were eligible to participate and recruited through convenience sampling. An online survey instrument that included validated measures of their children’s physical activity (unstructured, organized, home-based, indoor/outdoor active play, dog play/walking), sociodemographic, and other potential confounders was administered to parents. Paired t-tests and mixed ANOVA models assessed changes in physical activity outcomes. The analytic sample comprised parents of 157 children who were 6.9 years of age (SD = 1.7) on average. Overall, weekly minutes of total physical activity (PA) did not change from before to during COVID-19. However, frequency and duration (total and home-based) of unstructured physical activity significantly increased. Outdoor play in the yard or street around the house, outdoor play in the park or playground or outdoor recreation area, and active indoor play at home all significantly increased. Frequency and total duration of organised physical activity significantly declined during COVID-19 distancing. During Western Australian COVID-19 restrictions, there was an increase in young children’s unstructured physical activity and outdoor play and a decrease in organised physical activity. It remains to be seen whether children’s increased physical activity has been sustained with the easing of physical distancing restrictions.

Background The aim of this study was to gain consensus on an evidence informed physical activity policy template for early childhood education and care (ECEC) and determine best-practice dissemination and implementation strategies using the Delphi process. Methods Three-round modified Delphi methodology. During round one an expert working group developed an evidence informed ECEC specific physical activity policy template. Rounds two and three involved national online surveys to seek insight from a group of experts on the draft physical activity policy template. Results Ninety per cent of experts reported ECEC services are fully responsible for having a physical activity policy. There was consensus on the components of the policy and key physical activity and sedentary behaviour statements and recommendations. The most effective methods for disseminating a physical activity policy to ECEC providers included online (websites, social and electronic media), ECEC targeted launch events, direct mail outs and via professional associations. Twenty five key strategies related to management, supervisors and educators; the ECEC physical environment; communicating with families; and accreditation, monitoring and review, were identified as necessary for the successful implementation of physical activity policy in ECEC. Experts reached consensus on nine of these strategies indicating they were both easy to implement and likely to have a high level of influence. Key barriers and enablers to implementing ECEC-specific physical activity were also identified. Conclusions This evidence informed physical activity policy template for ECEC provides recommendations on the amount of physical activity and sedentary time (including screen time) children should have whilst attending ECEC and aligns with national/international guidelines. A number of effective physical activity policy implementation strategies for ECEC were identified. An important next step is advocating for the introduction of legislative requirements for services to have and implement a physical activity policy.

Background Daily physical activity is critical during the early years of life for facilitating children’s health and development. A large proportion of preschool children do not achieve the recommended 3 h of daily physical activity. Early childhood education and care (ECEC) services are a key setting to intervene to increase physical activity. There is a significant need for ECEC specific physical activity policy, including clearer guidelines on the amount of physical activity children should do during care, and strategies for implementation of these guidelines. Methods This study is a pragmatic cluster randomised trial to evaluate the effectiveness of the Play Active physical activity policy intervention to improve early childhood education and care educator’s physical activity-related practices. The central component of Play Active is an evidence-informed physical activity policy template which includes 25 practices to support nine age-specific recommendations on the amount of physical activity and sedentary time, including screen time, young children should do while in care. There are six implementation support strategies to facilitate physical activity policy implementation: (i) personalise policy (services select at least five of the 25 practices to focus on initially); (ii) policy review and approval; (iii) a resource guide; (iv) a brief assessment tool for monitoring children’s energetic play; (v) professional development; and (vi) Project Officer implementation support (phone calls). A total of 60 early childhood education and care services will be recruited from metropolitan Perth, Western Australia. After baseline assessment, services will be randomly allocated to either intervention or wait-listed comparison conditions. Primary (educator-reported frequency and amount of daily time provided for children’s physical activity, sedentary and screen time) and secondary (educator physical activity-related practices, self-efficacy, motivation, attitudes and beliefs, social support, and supportive physical environment) outcomes will be assessed at baseline and post-intervention, after intervention services have had a minimum 3 months of policy implementation within their service. Discussion The Play Active trial will rigorously evaluate a novel physical activity policy intervention with implementation support that promotes positive physical activity behaviours in educators and children attending ECEC. If effective, the program could be adapted, scaled-up and delivered in ECEC services nationally.
