Study Overview
Brief Summary
This study examines the effectiveness and appropriateness of a written physical activity policy implemented in licensed centre-based childcare on the physical activity levels of toddlers (1-2) and preschoolers (3-5 years). Half of the childcare centres will adopt the physical activity policy while the other half will continue with their typical daily programming and care. It is hypothesized that children enrolled in childcare centres that adopt the policy will display increased levels of physical activity during, and after participating in the policy intervention compared to children enrolled in centres that do not adopt the policy.
Detailed Description
A pilot, cluster single-blind randomized controlled trial (RCT) will be conducted. Approximately 8 licensed childcare centres will be randomly selected from an online listing of centres in London, Canada. Since it is necessary to implement the policy at the centre-level to groups of children, the childcare centres (i.e., the clusters) rather than the individual participants, will be randomly allocated to either implement the physical activity policy (experimental; n = 4), or maintain their daily programming (control; n = 4) for the 8-week intervention period.
In both groups, toddlers' and preschoolers' physical activity will be objectively measured using motion sensors (ActiGraph wGT3X-BT accelerometers) worn on an elastic waistband for 5 consecutive days, during childcare hours, before the policy is implemented (baseline; week 0; September 2018), mid-intervention (week 4; October 2018), one week after the intervention period ends (post-intervention; week 9; November/December 2018), and 6-months post-intervention (May-June 2019).
The aim of the study is to examine the impact of a childcare physical activity policy on the objectively measured physical activity levels (light physical activity, LPA; moderate-to-vigorous physical activity, MVPA), and combined total physical activity (TPA), and sedentary time of young children in childcare centres compared to children from centres that maintain their usual standard of care.

Masking Description
Children and childcare providers will be aware of whether or not they receive the intervention. However, research assistants who are collecting data will remain blind to each centre's group assignment.

Arms & Interventions
PLAY (PhysicaL ActivitY) Policy Intervention
The childcare physical activity policy will be adopted for 8 weeks within participating toddler and preschool classrooms of facilities allocated to the experimental group.
Intervention: PLAY (PhysicaL ActivitY) Policy Intervention (Behavioral)
Control group
Childcare centres will maintain their typical daily programming and standard of care for the duration of the 8-week intervention period.
Outcomes
Primary Outcomes
Changes in young children's Total Physical Activity (TPA)
Time Frame: Measured for 5 consecutive days at baseline (i.e., week 0), mid-intervention (i.e., week 4), post-intervention (i.e., week 9), and at 6-months post-intervention.
TPA, the accumulation of light-, moderate-, and vigorous-intensity physical activity will be assessed using ActiGraph wGT3X-BT accelerometers worn on each child's right hip for 5 consecutive days during childcare hours only at 4 time-points. Differences in TPA will be compared across groups (control vs. experimental) and over time (i.e., week 0, week 4, week 9, and 6 months post-intervention).
Secondary Outcomes
- Changes in children's Moderate-to-Vigorous Physical Activity (MVPA)(Measured for 5 consecutive days at baseline (i.e., week 0), mid-intervention (i.e., week 4), post-intervention (i.e., week 9), and at 6-months post-intervention.)
- Changes in children's Sedentary Time (ST)(Measured for 5 consecutive days at baseline (week 0), mid-intervention (week 4), post-intervention (week 9), and at 6-months post-intervention.)
- Self-efficacy scale for physical activity(Providers will be asked to complete this survey one week prior to baseline measures (Time 1), at baseline (i.e., week 0; Time 2), then again at mid-intervention (i.e., week 4; Time 3), post-intervention (i.e., week 9; Time 4), and at 6 months follow-up.)
- Environment and Policy Assessment and Observation Self-Report Today (EPAO-SR Today)(Administered to childcare providers in participating classrooms to complete once at baseline (i.e., week 0), mid-intervention (i.e., week 4), post-intervention (i.e., week 9), and at 6-months follow-up.)
- Policy intervention implementation log(Childcare providers within participating classrooms will be asked to complete the log on three days of each week of the 8-week intervention period.)
- Director Environment and Policy Assessment and Observation Self-Report (EPAO-SR)(Completed at baseline (i.e., week 0) only.)
- Feasibility and appropriateness(Conducted post-intervention (after week 9))
