The aim of the study is to compare, in coronary artery disease patients, physical
activity (PA) assessed with the Dijon Physical Activity Questionnaire (DPAQ) and
the true PA objectively measured using an accelerometer. Seventy patients wore an
accelerometer (MyWellness Key actimeter) throughout 1 week after a cardiac
rehabilitation program that included therapeutic education about regular PA.
Patients completed the DPAQ at the end of the week. The mean weekly active energy
expenditure was 619.9+/-374.6 kcal, and the mean DPAQ score was 21.3+/-3.1/30
points. There were low but significant correlations between total active energy
expenditure and the DPAQ score (rho=0.4, P=0.009). There were no correlations
between peak power output and total DPAQ score. The DPAQ significantly correlates
with objective measures given by the MyWellness Key actimeter. The choice between
these tools relies on the clinician's appreciation, taking into account patients'
characteristics and goals as well as the cost of the method and availability of
the tool.
