BACKGROUND: Study of the causes of the reduced levels of
                physical activity in patients with COPD has been scarce and
                limited to biological factors. AIM: To assess the relationship
                between novel socio-environmental factors, namely dog walking,
                grandparenting, neighbourhood deprivation, residential
                surrounding greenness and residential proximity to green or blue
                spaces, and amount and intensity of physical activity in COPD
                patients. METHODS: This cross-sectional study recruited 410 COPD
                patients from five Catalan municipalities. Dog walking and
                grandparenting were assessed by questionnaire. Neighbourhood
                deprivation was assessed using the census Urban Vulnerability
                Index, residential surrounding greenness by the
                satellite-derived Normalized Difference Vegetation Index, and
                residential proximity to green or blue spaces as living within
                300 m of such a space. Physical activity was measured during 1
                week by accelerometer to assess time spent on
                moderate-to-vigorous physical activity (MVPA) and vector
                magnitude units (VMU) per minute. FINDINGS: Patients were 85%
                male, had a mean (SD) age of 69 (9) years, and
                post-bronchodilator FEV1 of 56 (17) %pred. After adjusting for
                age, sex, socio-economic status, dyspnoea, exercise capacity and
                anxiety in a linear regression model, both dog walking and
                grandparenting were significantly associated with an increase
                both in time in MVPA (18 min/day (p<0.01) and 9 min/day
                (p<0.05), respectively) and in physical activity intensity
                (76 VMU/min (p=0.05) and 59 VMUs/min (p<0.05), respectively).
                Neighbourhood deprivation, surrounding greenness and proximity
                to green or blue spaces were not associated with physical
                activity. CONCLUSIONS: Dog walking and grandparenting are
                associated with a higher amount and intensity of physical
                activity in COPD patients. TRIAL REGISTRATION NUMBER:
