Evaluation of health-promoting self-care behaviors in hypertensive patients with concomitant chronic kidney disease in primary care.

Aim: This study was to investigate the relationships among health behaviors and quality of life (QOL) and to test a proposed model among people with hypertension and concomitant chronic kidney disease (CKD) in primary care. In addition, the mediation effect of modifiable risk factors between self-care health behaviors and QOL was examined. Methods: This study was prospective, conducted in the centers of primary medical care in the period from January 2018 to January 2020. In total, 170 patients diagnosed with hypertension and CKD at least 12 months previously were included in this study. The following parameters were measured: self-efficacy, self-care health behaviors with the subscales of health responsibility, exercise, consumption of a healthy diet, stress management, and smoking cessation; modifiable risk score; and QOL (assessed using the 36-item Short-Form Health Survey instrument). Results: Self-efficacy had a significantly positive direct effect on self-care health behaviors, with a standardized regression coefficient of 0.87 (P = 0.007), a negative indirect effect on risk factors, with a standardized regression coefficient of 0.11 (P = 0.006), and a positive indirect effect on QOL, with a standardized regression coefficient of 0.62 (P = 0.008). Self-care health behaviors had a significantly positive direct effect on QOL, with a standardized regression coefficient of 0.72 (P = 0.012); there was also an indirect effect of 0.053 (P = 0.004). The direct effect of risk factors on QOL was significant, with a standardized regression coefficient of 0.44 (P = 0.018). The direct effect of self-care health behaviors on QOL was 0.77 (P = 0.008), which has been reduced to 0.72 (P = 0.012). The reduced effect of 0.05 was significant (P = 0.004), confirming the mediating role of modified risk factors. Conclusions: This study indicates health-promoting behaviors in hypertensive patients with CKD have a potential impact on their QOL in primary care. Primary care physicians should focus on motivation strategies to encourage individuals to perform self-care health-promoting behaviors associated with the improved QOL, in order to achieve better outcomes in risk factor management.
