In people with chronic obstructive pulmonary disease (COPD), there is increasing recognition that the prolonged accumulation of sedentary time (ST) is associated with adverse cardio-metabolic health outcomes. Nevertheless, changing this lifestyle, which has evolved over several decades, is likely to be challenging. This study reports the determinants, perceived by individuals with COPD, as being important for reducing ST. An in-depth understanding of this information is essential when planning an intervention to reduce ST. Fourteen individuals with COPD completed semi-structured one-on-one interviews, which were audio recorded and transcribed verbatim. Both the interview schedule and mapping of data items extracted from the interview transcripts were informed by the Theoretical Domains Framework (TDF). A total of 867 quotes were mapped to the 14 TDF domains. Seven of the fourteen domains were identified as being important determinants for reducing ST: knowledge, beliefs about consequences, beliefs about capabilities, environmental context and resources, social influences, social/professional role and identity, and behavioural regulation. There was a lack of knowledge regarding the meaning of sedentary behaviour. Participants' desire to be educated by knowledgeable health professionals in a formal programme was a dominant theme across multiple domains. The most frequently reported barriers to reducing ST related to the domains of social/professional role and identity and environmental context and resources, while the most frequently reported enablers were related to the domains pertaining to beliefs about consequences and social influences. Potential strategies to reduce ST among people with COPD include education and other determinants identified in this research.
在慢性阻塞性肺疾病（COPD）患者中，人们越来越认识到，久坐时间（ST）的长时间积累与不良的心血管代谢健康结果有关。然而，改变这种几十年演变而来的生活方式可能具有挑战性。本研究报告了 COPD 患者认为对减少 ST 重要的决定因素。在计划减少 ST 的干预措施时，深入了解这些信息至关重要。14 名 COPD 患者完成了半结构化的一对一访谈，访谈内容进行了录音并逐字转录。访谈计划和从访谈记录中提取的数据项的映射均由理论领域框架（TDF）提供信息。共有 867 条引语映射到 14 个 TDF 领域。14 个领域中有 7 个被确定为减少 ST 的重要决定因素：知识、对后果的信念、对能力的信念、环境背景和资源、社会影响、社会/职业角色和身份以及行为调节。对于久坐行为的含义缺乏了解。参与者希望在正式计划中接受知识渊博的卫生专业人员的教育，这是多个领域的主导主题。减少 ST 的最大障碍与社会/职业角色和身份以及环境背景和资源领域有关，而最常报道的促进因素与关于后果和社会影响的信念领域有关。减少 COPD 患者 ST 的潜在策略包括教育和本研究中确定的其他决定因素。
