Abstract
Background: Physical activity (PA) is heterogeneous among patients with COPD, little is known about correlates of PA beyond physiological factors.
Aim: Investigating correlates of PA in patients with COPD, taking an ecological approach through a broad spectrum of COPD.
Methods: In this observational analysis, mean steps per day were objectively measured for 7 consecutive days by the Dynaport MoveMonitor in outpatients with COPD. Data on physiological, psychological, socio-demographic, interpersonal factors and seasonality were collected. Univariate regression analysis or ANOVA was used to investigate the relationship between PA and possible correlates of PA.
Results: For this preliminary analysis, cross-sectional data on 95 patients with COPD (mean±SD 67±8 years, 60% male, FEV1 57±16%pred, 6MWD 462±106m, 5655±3904 steps/day) showed a significant univariate relationship between mean steps per day and exercise capacity, quadriceps muscle force, symptoms of dyspnea, importance of PA and fatigue (table 1). The relationship between these variables and PA was stronger in patients with 6MWD<450m compared to patients with a better 6MWD.
Additionally, PA was associated with the presence of cardiovascular comorbidities and season. No other physiological, psychological, socio-demographic and interpersonal factors were related to objective PA (table 1).
Conclusion: PA is a complex concept and we could not identify strong extra-personal correlates for PA.
