From: Validity of the international physical activity questionnaire short form (IPAQ-SF): A systematic review

Reference Cutoff used IPAQ-SF MET-min/wk Accelerometer MET-min/wk Over-report %
(based on accelerometer as criterion)
Lachat 2008 [35] Trost 1512 812 86%
Macfarlane 2007 [19] Freedson 3931 1440 173%
Dinger 2006 [25] Freedson 2607 1299 101%

  1. MET: metabolic equivalent task
  2. Trost: MET = 2.757+(0.0015 × counts/min) -0.08957 × age)-(0.000038 × counts/min×age)
  3. Swartz: moderate PA: 574≤ count/min ≤4945, vigorous PA: count/min > 4945
  4. Freedson: moderate PA: 1952≤ count/min ≤5724, vigorous PA: count/min > 5724
