The purpose of this study is to assess the prevalence and preferences of moderate-to-vigorous physical activities (MVPA) in patients with advanced lung cancer, explore the social cognitive factors that were associated with MVPA and interest in PA counseling and program, and examine the mediating role of social cognitive factors.
This was a cross-sectional study. Questionnaires on PA levels, PA counseling and programming preferences, and social cognitive variables (social support and self-efficacy) were administered to 105 patients with advanced lung cancer. Linear regression model was used to explore the social cognitive factors associated with MVPA, and logistic regression model was used to explore the factors associated with interest in PA counseling and program. Mediation analysis was used to examine the mediating role of self-efficacy on social support and MVPA.
Merely 30.5% of patients met the recommended level of MVPA; however, the majority of patients (89.5%) were interested in PA program. Social support (β = 0.60; p = 0.007) and self-efficacy (β = 1.06; p = 0.027) were positively associated with MVPA. Specifically, self-efficacy mediated the relationship between social support and MVPA (β = 0.63, p = 0.004).
The majority of the patients with advanced lung cancer did not meet the recommended level of MVPA; however, they are interested in receiving PA counseling and joining PA programs. Social support was key to promoting higher levels of MVPA, and the association was mediated by self-efficacy. The established mediating model provides insights into designing PA programs and targeting the mediating variable, self-efficacy, to enhance the level of MVPA.
本研究旨在评估晚期肺癌患者进行中高强度身体活动（MVPA）的流行率和偏好，探讨与 MVPA 及对 PA 咨询和项目的兴趣相关的社会认知因素，并检验社会认知因素的中介作用。
这是一项横断面研究。向 105 例晚期肺癌患者发放关于 PA 水平、PA 咨询和项目偏好以及社会认知变量（社会支持和自我效能）的问卷。采用线性回归模型探讨与 MVPA 相关的社会认知因素，采用逻辑回归模型探讨与对 PA 咨询和项目的兴趣相关的因素。采用中介分析检验自我效能在社会支持与 MVPA 之间的中介作用。
仅有 30.5%的患者达到了 MVPA 的推荐水平；然而，大多数患者（89.5%）对 PA 项目感兴趣。社会支持（β=0.60；p=0.007）和自我效能（β=1.06；p=0.027）与 MVPA 呈正相关。具体而言，自我效能在社会支持与 MVPA 之间起中介作用（β=0.63，p=0.004）。
大多数晚期肺癌患者未达到 MVPA 的推荐水平；然而，他们有兴趣接受 PA 咨询并参加 PA 项目。社会支持是促进更高水平 MVPA 的关键，这种关联是由自我效能介导的。所建立的中介模型为设计 PA 项目和针对中介变量自我效能以提高 MVPA 水平提供了思路。
