Table 2 Baseline 7D-PAR (self-reported) and accelerometer (objectively measured) physical activity (N = 215)

From: New insights into discrepancies between self-reported and accelerometer-measured moderate to vigorous physical activity among women – the mPED trial

Physical activity measures Median /mean (±SD) or % (n)
7D-PAR (self-report)  
 Weekly total minutes of MVPA with 10 min criteria 160 /197 (±175) or
 Last week’s physical activity level, compared to the past 3 months
    Same 61.8 (133)
    Less 24.2 (52)
    More 14.0 (30)
 Meeting a 150 min/week of MVPA recommendation with 10 min criteria 54.5 (117)
Accelerometer (objective measure)
 Weekly total minutes of MVPA by accelerometer with the 10 min criteria without allowing for any interruption 14/38 (±62)
 Weekly total minutes of MVPA by accelerometer with the 10 min criteria allowing for a 1 or 2 min interruption 24/48 (±61)
 Weekly total minutes of MVPA by accelerometer with the 7 min criteria 33/59 (±75)
 Weekly total minutes of MVPA by accelerometer with the 5 min criteria 56/85 (±87)
 Weekly total minutes of MVPA by accelerometer with the 3 min criteria 120/138 (±104)
 Weekly total minutes of MVPA by accelerometer with the 1 min criteria 285/300 (±147)
Meeting a 150 min/week of MVPA recommendation by accelerometer
 10 min criteria not allowing any interruption 4.7 (10)
 10 min criteria allowing for a 1 or 2-min interruption 8.4 (18)
 7 min criteria not allowing any interruption 8.4 (18)
 5 min criteria not allowing any interruption 17.2 (37)
 3 min criteria not allowing any interruption 35.8 (77)
 1 min criteria 87.0 (187)
Self-reported physical activity questionnaires Mean (±SD)
