This research aims to identify one or more programs for parents of children aged 2-6 years that are effective in improving their child’s health behaviours (nutrition, physical activity, sedentary time and sleep). The programs will be implemented in NSW and contribute to the Premier’s Priority to reduce childhood overweight and obesity by 5 per cent by 2025.
The study will employ a three-arm parallel-group randomised preference trial design of a telephone-based intervention (modified Healthy Habits), an online intervention (modified Time2bHealthy) and educational material intervention (which will serve as a minimal intervention comparison).
The study will address the following research questions:
1. What is the relative effectiveness and cost effectiveness of an online behaviour change program (Time2bHealthy) and a telephone-based support program (Healthy Habits) targeting parents of 2-6 year olds in improving child diet in accordance with Australian recommendation?
2. What is the relative effectiveness and cost effectiveness of the Time2bHealthy and Healthy Habits programs on child physical activity, sedentary behaviour (including screen time), sleep and weight status?
3. What are the most optimal approaches to maximise recruitment to and retention of parents in both interventions?
