The overall aim of this study was to validate the EPIC physical activity questionnaire across EPIC centres. In addition, the validity of a newly derived questionnaire suitable for use in future follow-up studies of the EPIC population (RPAQ – Recent Physical Activity Questionnaire) and the short, last 7 day self-administered version of the International Physical Activity Questionnaire (IPAQ) was also tested.
This study was carried out across 10 European centres. In the UK site, a total of 219 healthy participants, with a gender distribution similar to the EPIC cohort and similar in age to those originally recruited for the baseline assessments in the EPIC study, were recruited. Participants were asked to visit the study site two times, with the second visit four months subsequent to the first. At the first visit, the following measures were taken: 1) anthropometric characterisation; 2) body composition measurements; 3) eight minute step test; 4) free-living physical activity assessment. The second visit mimicked the first, with the addition of the three physical activity questionnaires. Average data on PAEE was used as the criterion instrument and compared to a 4 level physical activity index (sedentary, moderately inactive, moderately active, active) based on occupational and cycling and other physical exercises.
Field work completed. Objective and subjective datasets from all centres is open to collaborative partners and has been used in number of publications. Further analysis and publication is ongoing.
