Table 2 Cross-sectional comparisons of MVPA, LPA and ST between weekdays and weekends at three time points

From: Longitudinal changes in objectively measured physical activity differ for weekdays and weekends among Chinese children in Hong Kong

  T1 (n = 263) T2 (n = 537) T3 (n = 421)
  Weekday Weekend Weekday Weekend Weekday Weekend
Wearing time (mind−1) 816 (90) 738 (132) 828 (84) 726 (98) 834 (96) 732 (126)
Daily time in minutes
 MVPA (mind−1) 61 (24) 70 (37) 51 (21) 53 (34) 46 (21) 48 (33)
 LPA (mind−1) 329 (74) 307 (76) 336 (68) 311 (75) 322 (70) 297 (79)
 ST (mind−1) 420 (79) 356 (108) 436 (79) 360 (91) 463 (86) 380 (107)
Proportion of time (% of wearing time)
 % MVPA 7.6 (2.9) 9.7 (5.3) 6.2 (2.6) 7.3 (4.6) 5.6 (2.5) 6.7 (4.8)
 % LPA 40.4 (7.0) 42.0 (7.8) 40.8 (6.7) 43.0 (8.2) 38.7 (6.9) 41.0 (8.8)
 % ST 52.0 (8.0) 48.3 (10.5) 53.0 (8.0) 49.7 (10.2) 55.7 (7.9) 52.3 (11.2)
  1. Values are means (SD); MVPA, moderate-to-vigorous physical activity; LPA light-intensity physical activity; ST sedentary time
  2. All differences between weekdays and weekend days are significant (p < 0.05) except for MVPA (mind−1) at T2 and T3
  3. No gender-outcome interactions were found; the results were combined for both boys and girls
