All models adjusted for gender, age, body mass index, physical function, marital status, educational attainment, and total accelerometer wear time.
β=Regression coefficients correspond to a 30 min increment of each activity.
*P<0.05.
SB, sedentary behaviour; LPA, light-intensity physical activity; MVPA, moderate-to-vigorous physical activity.
