Objectives: The purpose of this study was to identify the associated factors with physical activities in people with chronic obstructive pulmonary diseases (COPD). Methods: This study enrolled 1,176 COPD patients aged 40 and over who had the pulmonary function test in 2013-2015 Korean National Health and Nutrition Examination Survey (KNHANES VI). The measured physical activities were self-reported walking and strength exercise. Descriptive statistics, chi-square test and multiple logistic regression analysis were used for statistical analyses. Results: The self-reported rates of walking and strength exercise were 45.1% and 26.6% among all the subjects. Age, gender, education level, income status, smoking status and stress perception were statistically significant associated with physical activities. Conclusions: Physical activity in patients with COPD was associated with non-modifiable factors including age, gender and socio-economic status and modifiable factors including smoking and stress perception. These findings suggest that a multi-dimensional program for patients with COPD comprising lifestyle modification and the amelioration of socioeconomic factors may be necessary to increase physical activity and improve health status from the long perspective.
