Exacerbations of COPD decrease physical activity. Physical activity interventions after these events are desirable but have had mixed results. Understanding the barriers to and enablers of physical activity may help to improve the results of these interventions. We aimed to assess the barriers to and enablers of physical activity after COPD exacerbation and their association with daily steps.
We carried out a cross-sectional analysis of patients with COPD enrolled during a hospitalisation for an exacerbation. Physical activity was measured with an accelerometer for 7 days after discharge. Patients completed an 6-point Likert scale questionnaire about 13 barriers to and nine enablers of physical activity. We analysed the association between each item and patients' daily step counts.
46 patients with a mean±sd forced expiratory volume in 1 s of 48.6±15.9% predicted completed the assessments. They were 65±10 years old, spent 8±2 days hospitalised and walked 5633±3314 steps·day after discharge. The patients who reported "breathlessness" as a barrier (≥2 out of 6 points on the Likert scale) took statistically fewer daily steps (median (25th-75th centile) 3813 steps·day (2664-5639 steps·day) 5549 steps·day (3692-9984 steps·day), p=0.034). There was a similar finding for those who reported "low mood" as a barrier (≥2 out of 6 points) (3813 steps·day (2456-5471 steps·day) 5426 steps·day (3612-8942 steps·day), p=0.047). If they considered "physical activity as healthy" as an enabler, they walked statistically more (5085 steps·day (3538-8703 steps·day) 2760 steps·day (2271-5298 steps·day), p=0.031).
Some barriers to and enablers of physical activity reported by patients after a COPD exacerbation relate to daily steps. Assessing physical activity barriers and enablers could be useful to improve future physical activity interventions after these events.
慢性阻塞性肺疾病（COPD）急性加重会降低身体活动水平。在这些事件发生后进行身体活动干预是可取的，但结果不一。了解身体活动的障碍和促进因素可能有助于改善这些干预措施的效果。我们旨在评估COPD急性加重后身体活动的障碍和促进因素及其与每日步数的关联。
我们对因急性加重而住院的COPD患者进行了横断面分析。出院后用加速度计测量7天的身体活动情况。患者完成了一份关于13个身体活动障碍和9个促进因素的6点李克特量表问卷。我们分析了每个项目与患者每日步数之间的关联。
46例患者完成了评估，其1秒用力呼气容积平均±标准差为预计值的48.6±15.9%。他们的年龄为65±10岁，住院8±2天，出院后每天步行5633±3314步。将“呼吸急促”报告为障碍（李克特量表上6分中≥2分）的患者，其每日步数在统计学上较少（中位数（第25-75百分位数）为每天3813步（2664-5639步）对5549步（3692-9984步），p=0.034）。将“情绪低落”报告为障碍（6分中≥2分）的患者也有类似发现（每天3813步（2456-5471步）对5426步（3612-8942步），p=0.047）。如果他们将“身体活动有益健康”视为促进因素，他们在统计学上步行更多（每天5085步（3538-8703步）对2760步（2271-5298步），p=0.031）。
COPD急性加重后患者报告的一些身体活动障碍和促进因素与每日步数有关。评估身体活动障碍和促进因素可能有助于改善这些事件后未来的身体活动干预措施。
