BACKGROUND: 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.
OBJECTIVES: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.
