  1. Regression coefficients correspond to a 60 min/day increment of each activity.
  2. All models were adjusted for age, education, marital status, body mass index, living status, income, working status, and smoking. The single-activity and isotemporal models were also adjusted for the accelerometer daily wear time.
  3. SB sedentary behaviour, LPA light-intensity physical activity, MVPA moderate-to-vigorous physical activity.
  4. *p < 0.05; **p < 0.001.
