Table 2 Performance of the overall IPAQ-SF: Correlations between the objective measures and the IPAQ-SF overall physical activity levels (MET score, time spent, or novel definition by investigators) from 16 studies

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

  1. AEE: average energy expenditure
  2. TEE: total energy expenditure
  3. MET: metabolic equivalent task
  4. MET min/wk (Freedson): moderate PA: 1952≤ count/min ≤5724, vigorous PA: count/min > 5724
  5. Studies cited more than once have been identified with the same superscript number
  6. 3 categories‡: novel definition [23] of: low, moderate, high
  7. #: Accelerometer counts were transformed to AEE, and then AEE was transformed to time spent on moderate and vigorous activity
