Resident loved ones of patients with COPD can play an important role in helping these patients engage in physical activity. We aimed to compare activity levels and exercise motivation between patients with COPD 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.
One hundred twenty-five patient/loved one dyads were cross-sectionally and simultaneously assessed. Sedentary behavior, 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.
Patients spent more time in sedentary behavior and less time in physical activity than their loved ones (P < .0001). More intrinsic regulation was observed in loved ones compared with patients (P = .003), with no differences in other constructs. Despite similar exercise motivation, patients with an active loved one spent more time in MVPA (mean 31 min/d; 95% CI, 24-38 min/d vs mean, 18 min/d; 95% CI, 14-22 min/d; P = .002) and had a higher likelihood of being active (OR, 4.36; 95% CI, 1.41-13.30; P = .01) than did patients with an inactive loved one after controlling for age, BMI, and degree of airflow limitation.
Patients with COPD 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.

慢性阻塞性肺疾病（COPD）患者的常住亲属在帮助这些患者进行体育活动方面可以发挥重要作用。我们旨在比较COPD患者及其常住亲属之间的活动水平和运动动机；在根据亲属的身体活动水平对患者进行分层后，比较相同的结局指标；并预测有身体活跃的常住亲属的患者进行身体活动的可能性。
对125对患者/亲属进行横断面同时评估。在自由生活条件下，使用三轴加速度计测量至少5天的久坐行为、轻度活动和中度至剧烈身体活动（MVPA）。研究了五种运动动机结构：无动机、外部调节、内摄调节、认同调节和内在调节。
与亲属相比，患者久坐行为时间更长，身体活动时间更短（P <.0001）。与患者相比，亲属中观察到更多的内在调节（P =.003），其他结构无差异。尽管运动动机相似，但在控制年龄、体重指数和气流受限程度后，有活跃亲属的患者MVPA时间更长（平均31分钟/天；95%CI，24 - 38分钟/天 vs平均18分钟/天；95%CI，14 - 22分钟/天；P =.002），且活跃的可能性更高（OR，4.36；95%CI，1.41 - 13.3；P =.01）。
尽管运动动机相对相似，但COPD患者比其亲属身体活动更少且久坐时间更长。然而，有活跃亲属的患者自身更活跃，且活跃的可能性更高。
