Abstract: Background　Physical activity is an excellent index to predict the mortality of patients with chronic obstructive pulmonary disease （COPD）.It is of great significance for COPD patients to obtain a higher level of physical activity in their daily life to reduce the risk of rehospitalization，improve the quality of life and improve the outcome of the disease.Objective　To analyze the experience and associated common facilitators and barriers of physical activity in COPD patients based on the interviews with such patients from a grade A tertiary hospital in Guangzhou，providing strategies for improving the level of daily physical activity，and encouraging long-term adherence to healthy behavior in these patients.Methods　By use of purposive sampling，stable COPD patients from Department of Respiratory Medicine，the Third Affiliated Hospital，Sun Yat-Sen University，were enrolled from October 2017 to April 2018，and were interviewed in a semi-structured way until content and theme saturations were reached.The interview results and non-verbal behavior observation data during the interview of 18 cases were finally included，and were analyzed with thematic analysis.Results　Three themes affecting daily physical activity of COPD patients were extracted：perception and motivation（including value cognition, experience, goal and motivation of physical activity），social support （including medical staff support, family support, peer support） and environmental resources（including seasons, lack of oxygen therapy assistance, community resources）.Conclusion　The physical activity of patients with COPD in Guangzhou is affected by many factors.To improve the level of physical activity，quality of life and outcome in such patients，it is necessary to increase patients and their family members' awareness of physical activity，integrate medical and social support resources，rationally use physical activity facilitators，and effectively solve barriers to physical activity.

摘要： 背景　体力活动状况是预测慢性阻塞性肺疾病（COPD）患者死亡率的一个极佳指标，COPD患者在日常生活中获得更高水平的体力活动有助于减少再住院风险、提高生活质量、改善疾病转归，具有重要意义。目的　对广州市某三甲医院COPD患者进行访谈，了解 患者进行体力活动的真实体验，明确常见促进和阻碍其进行体力活动的因素，为提高COPD患者日常体力活动水平，鼓励坚持长期健康行为提供策略。方法　采用目的抽样法，抽取2017年10月—2018年4月就诊于中山大学附属第三医院呼吸内科门诊的稳定期COPD患者作为研 究对象，研究样本量以受访者的资料重复出现且资料分析时不再有新的主题呈现为标准。最终访谈18例患者，采用半结构访谈结合观察法收集资料，应用主题分析法进行资料分析。结果　提炼出影响COPD患者体力活动状况的3个主题：感知与动机（包括对体力活动的价值 认知，体力活动的经历，目标和动机）、社会支持（包括医务人员的支持，家庭支持，同伴支持）、环境资源（包括季节，缺乏氧疗的协助，社区资源）。结论　广州市COPD患者的体力活动状况受到多种因素影响，应唤醒患者及家属对体力活动的关注度，整合医疗社会 支持资源，合理利用促进因素，有效解决障碍因素，以促进COPD患者体力活动水平、提高生活质量、改善疾病转归。
