Resum
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:
