Table 5 Differences between accelerometer and the Global Physical Activity Questionnaire measurements based on body mass index

From: Convergent validity: agreement between accelerometry and the Global Physical Activity Questionnaire in college-age Saudi men

Variables Underweight (n = 17) Normal weight (n = 26) Overweight (n = 9) Obese (n = 9) p value
∆ MVPA (min/week) 9.0 (−74.0 to 220.0) 59.0 (−161.0 to 149.0) 68.0 (26.0–152.0) −121.0 (−412.0 to 2.0) 0.21
∆ Sedentary time (min/day) 98.5 (14.0–171.7) 224.2 (49.5–383.4) 278.3 (161.0–313.6) 313.4 (201.6–388.0)a 0.03
  1.  data measured using accelerometer–data reported using the GPAQ
  2. Underweight (BMI <18.5 kg/m2), Normal weight (BMI 18.5–24.9 kg/m2), Overweight (BMI 25.0–29.9 kg/m2), Obese (BMI ≥30.0 kg/m2)
  3. Data presented as median (1st–3rd quartiles)
  4. GPAQ Global Physical Activity Questionnaire, BMI body mass index, MVPA moderate-vigorous physical activity
  5. aIndicates a significant difference from Underweight, p ≤ 0.05
