社会生态学视角下老年COPD患者久坐行为的影响因素

Influencing Factors of Sedentary Behavior in Elderly Patients with COPD from the Perspective of Social Ecology

摘要: 久坐行为已成为影响老年慢性阻塞性肺疾病(COPD)患者预后的重要独立危险因素。本文基于社会生态学理论框架，系统梳理了老年COPD患者久坐行为的个体、人际、社区及政策层面影响因素。个体层面，呼吸困难、活动恐惧、疾病认知偏差及负性情绪是主要内在驱动；人际层面，家庭过度保护或支持不足、社交网络减弱以及医护人员行为指导能力有限均显著调节久坐时间；社区与环境层面，建成环境障碍、社区资源可及性与安全性直接制约活动机会；政策与医疗体系层面，公共卫生政策对久坐行为关注不足、肺康复可及性低下及跨部门协作缺失构成宏观屏障。在此基础上，本文从个体、家庭、社区及政策等层面系统分析了影响久坐行为的关键因素，以期为打破活动减少、功能下降与久坐增多之间的恶性循环、构建本土化干预方案提供理论依据。

Abstract: Sedentary behavior has been recognized as a significant independent risk factor affecting the prognosis of elderly patients with chronic obstructive pulmonary disease (COPD). Drawing upon the socio-ecological model, this paper systematically reviews the multi-level factors influencing sedentary behavior in this population, spanning individual, interpersonal, community, and policy domains. At the individual level, dyspnea, fear of activity, misconceptions about the disease, and negative emotions are primary intrinsic drivers. Interpersonally, overprotection or insufficient support from family, weakened social networks, and limited behavioral guidance capabilities of healthcare providers significantly modulate sedentary time. At the community and environmental level, barriers in the built environment, limited accessibility of community resources, and safety concerns restrict opportunities for physical activity. At the policy and healthcare system level, insufficient attention to sedentary behavior in public health policies, low accessibility of pulmonary rehabilitation, and lack of cross-sectoral collaboration constitute macro-level barriers. Building on this analysis, integrated multi-level intervention strategies are proposed, emphasizing individualized cognitive-behavioral interventions, family-inclusive support, age-friendly community environmental optimization, and policy-resource integration, with the aim of breaking the vicious cycle of “reduced activity-functional decline-increased sedentariness” and providing a theoretical basis for the development of localized intervention programs.
