Table 2.
Panel A: means with standard deviations and medians with inter-quartile ranges for total minutes of sedentary, all measures. Panel B: proportion of MSTQ-reported waking time spent sitting and proportion of accelerometer wear-time <100 counts (relative sedentary time).
| A | MSTQ (minutes sitting) |
Activity Log (minutes sitting) |
Accelerometer (minutes <100 counts) |
B | MSTQ % (% of waking time sitting) |
Relative accelerometer (% weartime <100 counts) |
