Factors Associated with Self-Regulatory Fatigue in Chinese Older Patients with Coronary Heart Disease: A Cross-Sectional Survey

PURPOSE: To identify important determinants of self-regulatory fatigue in older adults with coronary heart disease based on demographics, health literacy, and health empowerment factors. PATIENTS AND METHODS: A total of 201 older patients with coronary heart disease (CHD) from First Affiliated Hospital of Jinzhou Medical University by cluster sampling method. Demographic Questionnaire, the Health Literacy Management Scale (HLSCP), the Patient Perception Empowerment Scale (PPES), and the Self-Regulatory Fatigue Scale (SRF-S) were used to collect the data. RESULTS: The coronary heart disease elderly scored 44.20±6.98 points in self-regulatory fatigue. The results showed that residence, monthly household income, hospitalized times of CHD since illness, health literacy and health empowerment were significant determinants of self-regulatory fatigue (p<0.001). Self-regulatory fatigue was negatively correlated with health literacy (r=−0.639, P<0.01) and health empowerment (r=−0.580, P<0.01). CONCLUSION: Residence, monthly household income, hospitalized times of CHD since illness influence self-regulatory fatigue among coronary heart disease patients. Health literacy and health empowerment were independent predictors of self-regulatory among coronary heart disease patients.
