C17 ADVANCES IN PHYSICAL ACTIVITY, PULMONARY REHABILITATION, AND EXERCISE TRAINING: Patterns Of Change In Daily Step Count Among COPD Patients Enrolled In A 3-Month Physical Activity Intervention

Description
Summary:Methods U.S. Veterans with stable COPD (defined as FEV1FVC ratio < 0.7 or radiographic evidence of emphysema on clinical chest computed tomography) were enrolled and randomized (1:1) to receive either a pedometer alone or a pedometer plus access to an interactive website which provided feedback, goal-setting, disease education, and an online community forum. Generalized linear mixed effects models for repeated measures with 1 st-order auto-regressive covariance matrices (PROC MIXED, SAS v9.4) were constructed with the difference between daily step count averaged weekly and baseline daily step count as the dependent variable and intervention group, time (in weeks), FEV1FVC ratio (included a priori), and season of intervention week as the independent variables.
