Study type
Interventional
Description of intervention(s) / exposure
An intervention to increase the time children spend in moderate to vigorous physical activity in childcare will be delivered to participating centre-based childcare services randomly allocated to the intervention group. Specifically, within a six hour day (9am-3pm) the intervention will involve childcare services implementing three brief (5 minute) structured physical activity sessions (energisers) each day for children aged 3 to 6 years. The energisers will involve educators leading all children in a brief activity or active game with the aim of increasing children's moderate to vigorous physical activity levels. Suggested energisers will be provided as an educational resource for educators. All other service practices will remain unchanged. Childcare services will receive support from the research team to implement three energisers each week day for a period of six months. The intervention will be guided by the socio-ecological framework and will involve the following components: i) obtaining service manager endorsement of the intervention; ii) face-to-face educational meeting with service manager and lead educators; iii) local consensus process with service manager and educators; iv) provision of educational resources designed specifically for this study; and v) tailored telephone support from the research team on a minimum of two occasions throughout the intervention period.

Minimum age
3 Years
Maximum age
6 Years
Gender
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Centre-based childcare services (long day care services and preschools)
Services catering solely for special needs populations will be excluded from participating in the trial, as will services already implementing daily energisers. NSW Department of Education and Communities services will also be excluded, together with services currently participating in alternate trials aiming to improve nutrition and/or physical activity.

Children
Children with an intellectual or physical impairment that may impact on their physical activity capacity or prevent them from complying with data collection protocols will be excluded from participating in the trial.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Childcare services
A list of all centre-based childcare services (preschools and long day care services) located within the study region will be obtained from the NSW Ministry of Health and will serve as the sampling frame (approximately n=420). The Nominated Supervisor of eligible services will be sent an information letter informing them about the study and requesting permission to recruit parents through their service. Approximately one week following the distribution of the information letters, a research assistant will telephone Nominated Supervisors to answer any questions they may have and to confirm their eligibility, consent or otherwise. Random allocation of services to groups will occur following baseline data collection. Allocation to groups will be conducted by an independent statistician, at a centralised location.

Parents/children
A member of the research team will arrange for recruitment packs (one per parent of each enrolled child aged 3 to 6 years) to be delivered to each participating service. Distribution of these packs to parents will occur via methods considered most effective and appropriate by the Nominated Supervisor in communicating with parents (e.g. placed in children’s pigeon holes or lockers, or handed directly to parents at drop-off or pick-up). The recruitment pack will contain an information sheet, consent form and return envelope. The information sheet will explain the study to parents and their opportunity to participate. Parents will be asked to return the consent form in the envelope provided to a drop-box at the service (supplied by the research team). Parents will have two to three weeks to return their consent form. Parents will be provided the direct phone number of a member of the research team to ask questions regarding research participation. One to two weeks after delivery of the recruitment packs, staff will be present at the childcare service, reminding parents of the study and the opportunity to participate. The research team has previously employed all methods of recruitment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Consenting childcare services will be randomly allocated to an intervention or control group in a 1:1 ratio via block randomisation using a random number function in SAS statistical software following baseline data collection. Allocation of services will be undertaken by an independent statistician who will otherwise have no involvement in the study. Randomisation of childcare services will be stratified by the socioeconomic status of the area where the service is located, and the service type (preschool or long day care service).

Statistical methods / analysis
Generalised Linear Mixed Models (GLMM), to take account of the clustering of individual children within services, will be used under an intention to treat framework to examine changes in the study outcomes between groups over time. Data on child physical activity and cognitive function will be assessed on a cohort of children.
The study will approach approximately 420 children from 14 childcare services across the study region. Assuming the standard deviation of moderate to vigorous physical activity is 21 minutes and assuming an intraclass correlation coefficient of 0.07, a sample of 30 children per cluster will be sufficient to detect a change of 10 minutes in moderate to vigorous physical activity in care, with 80% power and an alpha of 0.05.

Summary
Brief summary
Childcare services are an important setting for interventions to improve child physical activity as they provide access to large numbers of children at a critical period in the development of healthy behaviours. Implementing brief structured physical activity sessions (energisers) may represent a simple and effective strategy which is suitable to ‘scale-up’ for population-wide implementation. However while several studies have investigated the impact of energisers on school-aged children’s physical activity, few have rigorously evaluated the impact of such an intervention on the activity levels of preschool-aged children.

This study hypothesises that when compared to children attending control services, children attending intervention services, where three daily energiser are implemented, will spend an additional 10 minutes in moderate to vigorous physical activity per day at childcare. An increase of 10 minutes of moderate to vigorous physical activity in preschool-aged children has been found to have clinically important effects on fat mass and peak bone mass.
