Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consists of one, 2-hour group discussion session, Positive Parenting for Baby Healthy Living, designed to target the direct and indirect pathways of parenting impact on infant obesity outcomes i.e. feeding practices, parenting practices, parents’ beliefs and knowledge, and parenting confidence and stress. The content draws on the theoretical principles that form the basis of Triple P, and is designed to be interactive and provide opportunities for discussion.

The Baby Healthy Living session focuses on providing parents with strategies that empower them to promote effectively good habits in their baby by having realistic expectations of their child and themselves, encouraging their baby’s self-regulation, setting early age appropriate limits and reducing stress. The session begins by exploring the challenges of being a parent in our society and discussing strategies to raise a healthy baby. The principles of positive parenting are then introduced as a way to promote babies’ healthy development (e.g. eating, sleeping, getting active) and manage infants’ behaviour and emotions in a constructive way. Finally, parents learn about coping strategies to manage stress.

Parents in the intervention receive a workbook and view a set of slides including short video segments. Detailed resources including a presentation guide and a session checklist are followed by the practitioner to guide them in delivering the session.

Behaviour
Comparator / control treatment
Families in the control group (Care As Usual) will be assessed on entry to the trial, 6 weeks later, and then again at 6 months. During this time, families will be free to access any resources they might need per usual. After the 6-month follow-up assessment families will be offered participation in the intervention.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A pre-prepared series of sealed opaque envelopes, each labelled with a participant ID number and containing a Randomisation Notification Letter, will be used to conceal the group allocation from both researchers and participants until after completion of the time 1 assessment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation of participants to either the intervention group or the care as usual control group will be done using a random allocation sequence generated using a computer-based random number generator.

Efficacy
Statistical methods / analysis
A power analysis was conducted to determine the required sample size. To detect a medium effect size of .30 with alpha set at .05, and power at .80, a minimum sample size of 55 participants per group is needed (i.e., N=110 for this two group study). Allowing for potential attrition of 20% the proposed sample size will provide sufficient power to
conduct the proposed analyses.

Summary
Brief summary
Existing data indicate that obesity affects individuals as early as the first two years of life and that overweight in infancy strongly predicts overweight in pre-school years and onwards. Thus, starting prevention during infancy appears essential. Despite this, preventive strategies targeting parents with children under the age of two are still in minority.
The present research project primarily aims to evaluate the efficacy of a brief, preventive Triple P parenting program (Baby Healthy Living) for parents with 4 to 18 months old children who may be at risk for overweight. The main goal of this intervention is to promote positive feeding practices and empower parents in setting healthy habits in infancy. The study targets families in more vulnerable situations (e.g., single parenthood, lower socio-economic status) who are at increased risk of having overweight or obese children. The intervention may benefit those families the most. If proven effective, such an intervention could make a significant difference in reducing risk factors associated with the early onset of childhood obesity.
