Abstract

Background  Resident loved ones of patients with COPD can play an important role in helping patients to engage in physical activity. We aimed to compare activity levels and exercise motivation between COPD patients and their resident loved ones; to compare the same outcome measures in patients after stratification for the physical activity level of the loved ones; and to predict the likelihood of being physically active in patients with a physically active resident loved one.

Methods  125 patient-loved one dyads were cross-sectionally and simultaneously assessed. Sedentary behaviour, light activities and moderate-to-vigorous physical activity (MVPA) were measured with a triaxial accelerometer during free-living conditions for at least 5 days. Five exercise motivation constructs were investigated: amotivation, external regulation, introjected regulation, identified regulation, and intrinsic regulation.

Results  Patients spent more time in sedentary behaviour and less time in physical activity than their loved ones (P<0.0001). More intrinsic regulation was observed in loved ones compared to patients (P=0.003), with no differences in other constructs. Despite similar exercise motivation, patients with an active loved one spent more time in MVPA (mean (95% CI) 31 (24, 38) vs 18 (14, 22) min·day-1; P=0.002) and had a higher likelihood of being active (OR (95% CI) 4.36 (1.41, 13.30); P=0.01) than patients with an inactive loved one after controlling for age, body mass index and degree of airflow limitation.

Conclusions  COPD patients are more physically inactive and sedentary than their loved ones, despite relatively similar exercise motivation. Nevertheless, patients with an active loved one are more active themselves and have a higher likelihood of being active.
