  • Data are presented as n (%) for categorical variables and median (IQR) for non-normally distributed continuous variables. P values represent a test of group differences by sex performed using χ2 tests or Kruskal-Wallis tests as appropriate. Bold font signifies statistically significant difference between women and men (p<0.05).

  • CVD, cardiovascular disease; M0.5, average acceleration above which the most active 30 min of the day were accumulated; MVPA, moderate-to-vigorous physical activity; Proportion SB, proportion of total SB time accumulated in bouts longer than 60 min; PWV, pulse wave velocity; SB, sedentary behaviour.
