Table 2 Test (test 1) and retest (test 2) of physical activity measures and reliability coefficient of IPAQ-SF, n = 88

From: Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women

PA intensity Test 1 PA measures min/week Mean (SD) Test 2 PA measures min/week Mean (SD) ICC (95%CI)
MPA 72.9 (141.3) 78.0 (132.4) 0.81 (0.71–0.88) (p < 0.001)
VPA 28.1 (61.3) 26.7 (69.9) 0.84 (0.74–0.90) (p < 0.001)
MVPA 95.5 (151.5) 107.6 (167.6) 0.81 (0.69–0.89) (p < 0.001)
  1. PA: physical activity
  2. SD: standard deviation
  3. ICC: intraclass correlation coefficient
  4. MPA: moderate physical activity
  5. VPA: vigorous physical activity
  6. MVPA: moderate to vigorous physical activity
