Table 4.

Comparison of International Physical Activity Questionnaire (IPAQ) and accelerometry-derived moderate-to-vigorous intensity physical activity and sedentary time for the 54 participants with valid data, and the 31 participants who participated in qualitative interviews. Data are mean ± standard deviation.

Variables All (n = 54) Sub-Sample (n = 31) p-Value from T-Test Comparison between All Participants and the Sub-Sample p-Value from T-Test Comparison between Accelerometer and IPAQ
IPAQ MVPA (MET–min/week) 675.7 ± 532.0 764.5 ± 549.9 p = 0.211 p < 0.001
IPAQ ST (min/day) 577.8 ± 860.7 723.6 ± 1155.0 p = 0.205 p < 0.001
Accelerometery MVPA (MET min/week) 1253.0 ±771.2 1409.3 ± 909.9 p = 0.195
Accelerometery ST (min/day) 551.4 ± 95.0 566.7 ± 95.4 p = 0.314

ST: Sedentary Time; MET: Metabolic Equivalent of Task.
