S.2.34 - Goldilocks and the Three Postdocs: Exploring the optimal day for health and wellbeing

Details
Purpose: To present and discuss novel analytical approaches for estimating the optimal balance of daily time-use behaviours. The optimal “Goldilocks” day will be explored using a range of health and wellbeing outcomes across the lifespan.
Rationale: Time-use behaviours, including device-based movement (e.g., sedentary time, physical activity) and self-reported contextual behaviours (e.g., reading, TV watching), impact health and wellbeing. However, spending more time in one behaviour means less available time in a day for the remaining behaviours. It is important that time-use behaviours are investigated simultaneously to account for their co-dependence. Compositional Data Analysis (CoDA) is recommended to investigate these behaviours concurrently rather than in isolation. However, few studies have used CoDA to investigate the ideal distribution of time-use behaviours for optimal health and wellbeing. Finding the optimal balance between behaviours has direct implications for informing the development of future guidelines and interventions.
Objectives:
1) Summarise recent methodological developments for estimating the “Goldilocks Day” for health and wellbeing across the lifespan.
2) Present different applications of the “Goldilocks Day” technique for determining optimal distributions of time-use behaviours, including device-based movement and self-reported contextual behaviours.
3) Discuss strengths, limitations, and future possibilities of using this technique for estimating optimal patterns of time-use behaviours for optimal health and wellbeing.
Summary: The chair will introduce CoDA and the concept of exploring the “Goldilocks Day”. All speakers will discuss the optimal distribution of time-use behaviours. Speaker 1 will focus on movement behaviours and self-reported overall health among young Australian adults. Speaker 2 will discuss self-reported contextual behaviours for health and wellbeing in youth. Speaker 3 will consider movement behaviour compositions, including longer and shorter physical activity and sedentary bouts, for perceived health in children. Finally, the discussant will synthesise the presented findings and reflect on how these contribute to understanding the optimal day for health and wellbeing. The discussion will also focus on strengths, limitations, and future directions of using CoDA to investigate the “Goldilocks Day” in order to advance this field.
