Influencing factors of physical activity among young and middle-aged patients with coronary heart disease: a multicenter cross-sectional study.

The rate of physical activity compliance among young and middle-aged patients with CHD was 34.36%.

• 326 young and middle-aged patients with CHD were surveyed across four tertiary hospitals in Hubei Province.
• 112 participants were classified in the qualified group (meeting guideline-recommended PA standards) and 214 in the non-qualified group.
• The qualified group represented 34.36% of the total sample.
• Assessment used the International Physical Activity Questionnaire-Long (IPAQ-L) to measure physical activity levels.

Binary logistic regression identified hemoglobin as a significant influencing factor of physical activity in young and middle-aged CHD patients.

• Hemoglobin was identified as a statistically significant predictor (P < 0.05).
• This represents a physiological factor contributing to PA levels.
• Analysis was performed using SPSS 25.0 with binary logistic regression.

Glycated hemoglobin was identified as a significant influencing factor of physical activity in young and middle-aged CHD patients.

• Glycated hemoglobin was a statistically significant predictor of PA compliance (P < 0.05).
• This represents a physiological/metabolic factor in the regression model.
• Univariate analysis preceded binary logistic regression to identify candidate variables.

Fear of movement (kinesiophobia) was a significant influencing factor of physical activity among young and middle-aged CHD patients.

• Fear of movement was measured using the Fear of Activity in Patients with Coronary Artery Disease (Fact-CAD) scale.
• It was identified as a statistically significant predictor in binary logistic regression (P < 0.05).
• This represents a psychological factor influencing PA levels.

Exercise self-efficacy was a significant influencing factor of physical activity among young and middle-aged CHD patients.

• Exercise self-efficacy was measured using the Exercise Self-Efficacy Scale (ESES).
• It was a statistically significant predictor in binary logistic regression (P < 0.05).
• This represents a psychological factor contributing to PA compliance.

Family care (family function) was a significant influencing factor of physical activity among young and middle-aged CHD patients.

• Family care was assessed using the Family Adaptation, Partnership, Growth, Affection, Resolve index (APGAR).
• It was identified as a statistically significant predictor (P < 0.05).
• This represents a social factor in the multivariate model.

Fatigue was a significant influencing factor of physical activity among young and middle-aged CHD patients.

• Fatigue was measured using the Piper Fatigue Scale-12 (PFS-12).
• It was identified as a statistically significant predictor in binary logistic regression (P < 0.05).
• This represents a physiological/psychological factor influencing PA levels.

The study used a cross-sectional multicenter design enrolling 326 young and middle-aged CHD patients from four tertiary hospitals.

• Data were collected from four tertiary hospitals in Hubei Province, China.
• Assessment tools included the IPAQ-L, Fact-CAD, ESES, APGAR, PFS-12, and Patient Health Questionnaire-9 items (PHQ-9).
• Participants were divided into qualified (n = 112) and non-qualified (n = 214) groups based on guideline-recommended PA standards.
• Statistical analysis involved univariate analysis followed by binary logistic regression using SPSS 25.0.
