Changing the behavior of physical activity (PA) in COPD patients remains a challenge, because this population faces the same barriers to PA as the general population, as well as disease-specific barriers, especially dyspnea-related kinesiophobia.
This study aimed to assess the status of dyspnea-related kinesiophobia in people with COPD, and investigate its impact on PA levels, further examine the mediated moderation effects of exercise perception and social support on this relationship.
A cross-sectional survey was conducted with COPD patients recruited from four tertiary hospitals in Jinan Province, China. We used Breathlessness Beliefs Questionnaire to identify dyspnea-related kinesiophobia. International Physical Activity Questionnaire-short-form, Exercise Benefits/Barriers Scale, and Social Support Rating Scale were used to assess PA, exercise perception and social support, respectively. The data were statistically processed using correlation analysis and a test of mediated moderation model.
A total of 223 COPD patients were included, and all of them had a symptom of dyspnea-related kinesiophobia. Dyspnea-related kinesiophobia was negatively correlated with exercise perception, subjective social support and PA. Exercise perception partially mediated the impact of dyspnea-related kinesiophobia on PA levels, and subjective social support indirectly influences PA by moderating the relationship between dyspnea-related kinesiophobia and exercise perception.
People with COPD commonly have dyspnea-related kinesiophobia and experienced physical inactivity. The mediated moderation model provides a better understanding of how dyspnea-related kinesiophobia, exercise perception, and subjective social support work together to influence PA. Interventions seeking to improve the levels of PA in COPD patients should consider these elements.
改变慢性阻塞性肺疾病（COPD）患者的身体活动（PA）行为仍然是一项挑战，因为该人群面临着与普通人群相同的PA障碍，以及特定疾病的障碍，尤其是与呼吸困难相关的运动恐惧。
本研究旨在评估COPD患者中与呼吸困难相关的运动恐惧状况，并调查其对PA水平的影响，进一步检验运动感知和社会支持对这种关系的中介调节作用。
对从中国山东省济南市四家三级医院招募的COPD患者进行横断面调查。我们使用呼吸困难信念问卷来识别与呼吸困难相关的运动恐惧。国际身体活动问卷简表、运动益处/障碍量表和社会支持评定量表分别用于评估PA、运动感知和社会支持。使用相关分析和中介调节模型检验对数据进行统计处理。
共纳入223例COPD患者，所有患者均有与呼吸困难相关的运动恐惧症状。与呼吸困难相关的运动恐惧与运动感知、主观社会支持和PA呈负相关。运动感知部分介导了与呼吸困难相关的运动恐惧对PA水平的影响，主观社会支持通过调节与呼吸困难相关的运动恐惧和运动感知之间的关系间接影响PA。
COPD患者普遍存在与呼吸困难相关的运动恐惧且身体活动不足。中介调节模型有助于更好地理解与呼吸困难相关的运动恐惧、运动感知和主观社会支持如何共同影响PA。旨在提高COPD患者PA水平的干预措施应考虑这些因素。
