Stationary time and physical activity level for participants included in the concurrent validity analysis (top) and the convergent validity analysis (bottom). All data are presented as median (Q1–Q3).

* Difference between women and men (Mann–Whitney U Test). MVPA: moderate to vigorous physical activity. ^a Standardized data to 16 h of wear time (960 min/day) in stationary and prolonged stationary time. ^b Prolonged stationary time: total stationary time in bouts ≥20 min; ^c SED-GIH and the question used by Katzmarzyk [3] are categorical with seven and five answer alternatives, respectively. IPAQ is an open-ended question [17]. Marshall is the sum of the domain-specific sitting question on weekdays [18,19].
