Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention involves educational content (e.g. What is tummy time?), an exercise class (e.g. the exercise is practising tummy time together with their baby) and a WhatsApp group to enable the mothers in the mother’s group to share tips, encouragement and strategies they have found helpful regarding infant physical activity. The intervention will be delivered by a Physiotherapist from a local Health district in NSW (Illawarra Shoalhaven) as an additional component to the health district's current mother's groups (groups of 6-10). The intervention (online class) will be implemented once and is approximately 60 minutes duration. Following this class, the mothers will be placed in a WhatsAPp group and standardized messages will be sent 3 times per week for 4 weeks. The intervention (online session) occurs at the last week of the mothers groups (4th week). The educational content (e.g. what is tummy time, benefits of tummy time, how to practice tummy time) will be accessed during the mother's groups via discussion, WhatsApp and printed information handouts, which will be delivered by the Physiotherapist. The intervention has been designed by the investigators of this study but is consistent with WHO recommendations for tummy time. Session attendance and WhatsApp messaging will be monitored by a research assistant.

Comparator / control treatment
The control group will recieve usual care, which is usual mother's groups (approxmately 2 hours duration), once per week, for three weeks, delivered by their Early Childhood Nurse. The usual care (groups of 6-10) will be delivered by Early Childhood Nurses from a local Health district in NSW (Illawarra Shoalhaven). Each session involves support relating to mothercraft, feeding, support and answer to questions posed by mothers about caring for their infant. Session attendance and topics covered will be monitored by a research assistant.

Active

Outcomes
Primary outcome [1] 326842 0
The primary outcome will be the amount of tummy time the infant received using the GENEActiv accelerometer. Mothers will be asked to place an accelerometer on their infant’s right hip (secured with a strap) for three, 24-hour periods during one week.
Timepoint [1] 326842 0
Post-intervention: 1 week after the completion of the intervention
Primary outcome [2] 327212 0
The primary outcome will be the amount of tummy time the infant received using a questionnaire. Mothers will be asked to complete a questionnaire to estimate the amount of time their infant spent in tummy time per day (a typical 24 hours in the last week). None; 1-15 minutes; 16-30 minutes; 31-60 minutes; >60 minutes.
Timepoint [2] 327212 0
Baseline: At least 1 week before starting mother's group
Post-intervention: 1 week after the completion of the intervention
Secondary outcome [1] 394250 0
Process measures: These will include intervention fidelity (measured by calculating (app analytics) the number of messages sent and received via WhatsApp®).
Timepoint [1] 394250 0
Post-intervention: 1 week post intervention

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be conducted by a computer program who will place the participant into the intervention or control group. Allocation involved contacting the holder of the allocation schedule who was "off-site" or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation
Masking / blinding

Efficacy
Statistical methods / analysis
Linear mixed models will be used to determine differences between intervention and control groups in changes in the primary outcome between baseline and post intervention. Intention-to-treat principles will be followed, with all participants analyzed in the group in which they are randomized. To calculate group mean estimates, the direct likelihood estimation method will be used to deal with any missing data (assuming that data are missing at random). Covariates will include sex, age, socioeconomic status, baseline tummy time and accelerometer wear time.
