Validation Studies of the European Prospective Investigation into Cancer and Nutrition (EPIC) Physical Activity Questions

Wareham et al. 2003

See reference #24

Methods
Relationship of EPIC Physical Activity Index (PAI), and physical activity ratio (PAR) calculated from 4-day heart-rate monitoring; VO2 max, energy intake/BMR assessed by 7-day food diaries (EI/BMR).
Sample
173 men and women; 40 to 65 years of age
Summary Results

Pols et al. 1996

See reference #27

Methods

Sample
33 women; 51-71 years of age
Summary Results
