Impact of the Play Active policy intervention on early childhood educator's sedentary behaviour‐related practices, psychosocial influences and meeting policy recommendations: Results from a pragmatic cluster randomized trial

Background
High levels of sedentary behaviour are associated with poor child health outcomes such as obesity. Early childhood education and care (ECEC) services are a key intervention setting. Most ECEC policy-based interventions focus on children's nutrition and physical activity with few aimed at children's sedentary behaviour.

Objective
To evaluate the effect of the Play Active ECEC policy intervention on educator adherence to sedentary behaviour policy recommendations, educator's practices and educator psychosocial influences related to children's sedentary behaviour.

Methods
Pragmatic cluster randomized trial in 81 ECEC services in Perth, Western Australia. Services implemented the Play Active policy over three months. Outcomes were educator-reported changes in adherence to sedentary behaviour policy recommendations, practices and psychosocial influences related to children's sedentary behaviour. Analysis involved descriptive statistics and generalized linear mixed-effects models.

Results
Adherence to sedentary behaviour policy recommendations and educator's practices and psychosocial influences related to children's sedentary behaviour was high at baseline and did not significantly change in response to the Play Active policy intervention.

Conclusions
Educators appeared to adhere to best-practice guidelines for children's sedentary behaviour in ECEC. Clear evidence informed policy, standards and legislation to maintain children's low levels of sedentary behaviours in ECEC is warranted.
