Objectives. This study investigated the activity behavior of patients with COPD in detail compared to asymptomatic controls, and the relationship between subjective and objective activities (awareness), and readiness to change activity behavior. Methods. Thirty-nine patients with COPD (66.0 years; FEV(1)% predicted: 44.9%) and 21 healthy controls (57.0 years) participated. Objective daily activity was assessed by accelerometry and expressed as amount of activity in counts per minute (cpm). Patients' baseline subjective activity and stage of change were assessed prior to measurements. Results. Mean daily activity in COPD patients was significantly lower compared to the healthy controls (864 ± 277 cpm versus 1162 ± 282 cpm, P < 0.001). COPD patients showed a temporary decrease in objective activities in the early afternoon. Objective and subjective activities were significantly moderately related and most patients (55.3%) were in the maintenance phase of the stages of change. Conclusions. COPD patients show a distinctive activity decrease in the early afternoon. COPD patients are moderately aware of their daily activity but regard themselves as physically active. Therefore, future telemedicine interventions might consider creating awareness of an active lifestyle and provide feedback that aims to increase and balance activity levels.
目的。本研究详细调查了慢性阻塞性肺疾病（COPD）患者与无症状对照组相比的活动行为，以及主观和客观活动之间的关系（认知），以及改变活动行为的意愿。方法。39例COPD患者（66.0岁；预测FEV(1)%：44.9%）和21名健康对照者（57.0岁）参与研究。通过加速度计评估客观日常活动，并以每分钟计数（cpm）表示活动量。在测量前评估患者的基线主观活动和改变阶段。结果。与健康对照组相比，COPD患者的平均每日活动量显著降低（864±277 cpm对1162±282 cpm，P<0.001）。COPD患者在下午早些时候客观活动出现暂时下降。客观和主观活动显著中度相关，大多数患者（55.3%）处于改变阶段的维持期。结论。COPD患者在下午早些时候活动明显减少。COPD患者对其日常活动有一定程度的认知，但自认为身体活跃。因此，未来的远程医疗干预可能会考虑提高对积极生活方式的认知，并提供旨在增加和平衡活动水平的反馈。
