Abstract

Sitting for prolonged periods of time impairs people’s health. Prior research has mainly investigated sitting behaviour on an aggregate level, e.g., by analysing total sitting time per day. By contrast, taking a dynamic approach, here we conceptualise sitting behaviour as a continuous chain of sit-to-stand and stand-to-sit transitions. We use multilevel time-to-event analysis to analyse the timing of these transitions. We analyse ~30,000 objectively-measured posture transitions from 156 people during worktime. Results indicate that the temporal dynamics of sit-to-stand transitions differ from stand-to-sit transitions, that people are quicker to switch postures later on the workday, and quicker to stand up after having been more active in the recent hours. We found no evidence for associations with physical fitness. Altogether, these findings provide insights into the origins of people’s stand-up and sit-down decisions, show that sitting behaviour is fundamentally different from exercise behaviour, and provide pointers for the development of interventions.
