Physical activity surveillance in the European Union: reliability and validity of the European Health Interview Survey-Physical Activity Questionnaire (EHIS-PAQ)

Table 4 Concurrent validity comparing the European Health Interview Survey Interview Physical Activity Questionnaire (EHIS-PAQ) with the International Physical Activity Questionnaire (IPAQ), 7-day Physical Activity Record (PAR), GT3X+ accelerometer, physical work capacity at 75 % maximum heart rate (PWC_75%), and grip strength
