Introduction.
The aim of the present study was to determine the closeness of agreement between a self-reported and an objective measure of physical activity in low back pain patients and healthy controls.
Beyond, influencing factors on overestimation were identified.
Methods.
27 low back pain patients and 53 healthy controls wore an accelerometer (objective measure) for seven consecutive days and answered a questionnaire on physical activity (self-report) over the same period of time.
Differences between self-reported and objective data were tested by Wilcoxon test.
Bland-Altman analysis was conducted for describing the closeness of agreement.
Linear regression models were calculated to identify the influence of age, sex, and body mass index on the overestimation by self-report.
Results.
Participants overestimated self-reported moderate activity in average by 42 min/day ( p = 0.003 ) and vigorous activity by 39 min/day ( p < 0.001 ).
Self-reported sedentary time was underestimated by 122 min/day ( p < 0.001 ).
No individual-related variables influenced the overestimation of physical activity.
Low back pain patients were more likely to underestimate sedentary time compared to healthy controls.
Discussion.
In rehabilitation and health promotion, the application-oriented measurement of physical activity remains a challenge.
The present results contradict other studies that had identified an influence of age, sex, and body mass index on the overestimation of physical activity.
