*Model 1 adjusted for age, sex and accelerometry wear time.

†Model 2 also adjusted for smoking, alcohol, education, BMI and social occupational group employment long-standing illness (non-mental only).

‡Model 3 also adjusted for tertiles of accelerometry-measured MVPA (for sedentary and light PA exposures) or sedentary time (for MVPA exposure).

BMI, body mass index; MVPA, moderate-to-vigorous physical activity; PA, physical activity.
