Abstract:Objectives: The prevalence of heart failure is increasing in the future and its growth is further enhanced by increasing average age. Studies have demonstrated the positive effects of physical activity on heart failure. The aim of this cross-sectional self-report study was to determine the relationship between psychosocial, demographic and medical factors, and the intention to and the performance of physical activity in patients with heart failure. Additionally, the role of the received advice with regard to physical activity was examined. The basis of this study was formed by the Protection Motivation Theory by Rogers (1975). Methods: 93 patients (76.3% man, median age of 70) with heart failure were included in the study. Participants completed a questionnaire for measuring physical activity (International Physical Activity Questionnaire, IPAQ), quality of live (Minnesota Living with Heart Failure Questionnaire, MLHFQ), heart-focused anxiety (Cardiac Anxiety Questionnaire, CAQ), role of the partner (Role Partner Questionnaire) and self-efficacy (Self-efficacy Questionnaire, SEQ). Several items were constructed for measuring the intention, severity of and vulnerability for heart failure, response efficacy en barriers in relation to physical activity. For the descriptive analyses medians, interquartilranges and percentages were calculated. The significant differences between the patients who did en did not receive an advice were examined by using Chi-square and Mann-Whitney U tests and logistic regression analyses were performed to predict the intention and physical activity. Results: About two third of the patients who received an advice concerning physical activity declared to have the intention of preforming physical activity. One half actually showed physical activity at a level of more than 600 MET-minutes per week. One quarter was not physically active at all. The intention for physical activity was significantly (p < 0.05) positively predicted by receiving an advice concerning physical activity and self-efficacy and negatively by perceived barriers. 81% of the model was explained by these factors. Physical activity was significantly (p < 0.05) positively predicted by receiving an advice concerning physical activity and perceived severity and vulnerability for heart failure and negatively predicted by avoidance of exertion and heart-focused sensations, response efficacy and perceived barriers. 58% Of the model was explained by these factors. Conclusion: This study provides unique in-depth insights into the predictors for physical activity and its intention. In particular psychosocial factors on the basis of the protection motivation theory form an important reference point for the future improvement of the supplied care in patients with heart failure.
