*Coefficients represent the change in the odds of obesity for an extra 1 h spent in sedentary time per day.
†Model 1 is adjusted for age, sex and accelerometer wear time (for models with accelerometry main exposure).
‡Model 2 is additionally adjusted for head of household occupational social class and portions of fruit and vegetable per day.
§Model 3 is additionally adjusted for self-reported MVPA or objectively measured MVPA, as appropriate.
CPM, counts per minute; MVPA, moderate to vigorous physical activity.
