To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Specifically, within a six hour day (9am-3pm) the intervention will involve services implementing continuous free indoor/outdoor play for children. The only time when an opportunity for outdoor free play will be unavailable for children is when structured activity is occurring. At all other times, children will be free to move between indoors and outdoors as they wish. All other service activities will remain unchanged. The duration of the intervention period will be approximately 3 months.
Services will be supported by a childhood physical activity consultant with experience working with childcare services to implement the intervention. Support will be provided via service visits and telephone calls. Adherence will be monitored by the external consultant who will ensure the intervention is delivered as per protocol (unless inclement weather, special events or offsite activities)

Outcomes
Primary outcome [1] 299065 0
Minutes children spend in moderate-to-vigorous physical activity from the time that children arrive at care until 3pm, measured by accelerometers using recommended cut-points. Accelerometer data will be collected on every day of one week.
Timepoint [1] 299065 0
At baseline and at the end of the intervention period (approximately 3 months after baseline)
Secondary outcome [1] 326053 0
% time in moderate-to-vigorous physical activity out of total activity in care assessed by accelerometers. Accelerometer data will be collected on every day of one week.
Timepoint [1] 326053 0
At baseline and at the end of the intervention period (approximately 3 months after baseline)
Secondary outcome [2] 326054 0
Total volume of activity (assessed via counts per 5 sec epoch) will also be assessed using accelerometers. Accelerometer data will be collected on every day of one week.
Timepoint [2] 326054 0
At baseline and at the end of the intervention period (approximately 3 months after baseline)
Secondary outcome [3] 326055 0
Adverse events. Child injuries requiring documentation assessed via Nominated Supervisor survey. The survey has been used in previous childcare-based physical activity studies.
Timepoint [3] 326055 0
At baseline and at the end of the intervention period (approximately 3 months after baseline)
Secondary outcome [4] 328379 0
Measures of child cognitive function (inhibitions, visual-spatial working memory and shifting) assessed via validated tool (Early Years Toolbox)
Timepoint [4] 328379 0
At baseline and at the end of the intervention period (approximately 3 months after baseline)

Eligibility
Key inclusion criteria
Childcare services (long day care services and preschools)
For a service to be eligible it will be within the Hunter New England geographic region of NSW Australia and have a minimum total number of children enrolled aged 3-6 years of at least 25.

Children
For children within the service to be eligible to participate they will be aged 3-6 years, have parental consent and attend care during any of the days of designated data collection.
Minimum age
3 Years
Maximum age
6 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Childcare services (long day care services and preschools)
Services serving special needs populations will be excluded from participating in the trial given the specialist care required for such children and the likelihood of a differential effect in this population group. Services already implementing continuous indoor/outdoor play within the core hours of 9am to 3pm will be deemed ineligible.

Children
Children at the service with special needs will be excluded from participating in the trial.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Childcare services
A current list of all childcare services in the Hunter New England region which have licensed places for 3 to 6 year olds will be obtained from the NSW Department of Health. The Nominated Supervisor of eligible services will be sent a letter informing them about the study and requesting permission to recruit parents through their service. Within two weeks from the initial information letters being sent, a study research assistant will telephone a Nominated Supervisor to answer any questions they may have and to confirm their eligibility, consent or otherwise.

Children
A member of the research team who will not be involved in intervention delivery will arrange for recruitment packs (one per parent of each enrolled child 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 engaging 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. Staff involved in recruitment of long day care services and children will be blind to the group allocation. Allocation to groups will be conducted by an independent statistician, at a centralised location using a computerised random number function. Random allocation of services to groups will occur following baseline data collection of children from childcare services.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A statistician with no involvement in the study procedures will allocate services to either the intervention or control condition in a 1:1 ratio using a computerised random number generator. Randomisation of services will be stratified by the socioeconomic status of the area where the service is located based on evidence of an association between services locality and services physical activity policies and practices.
