Objective: To evaluate the prevalence of depression and the association between depression and health-related quality of life among hemodialysis (HD) and peritoneal dialysis (PD) patients.
Materials and Methods: This analytical cross-sectional study was conducted using the Beck Depression Inventory Thai version (BDI-II) and the Kidney Disease Quality of Life Short Form Thai version (KDQOL-SF) during July 1st-November 19th 2015. Linear regression was used to analyze an association between depression and quality of life. Meanwhile, logistic regression was performed to determine association between dialysis modality and depression level categorized into two groups; depression (BDI-II≥14), and no depression (BDI-II<14).
Results: Of 81 dialysis patients; 60.5% was male, mean±standard deviation age was 57.9±13.6 years old. Forty and 41 patients underwent HD and PD, respectively. Overall, dialysis patients had the prevalence of depression of 35.8% (95% confidence interval (95% CI)=25.4-47.2), 37.5% (95% CI=22.7-54.2) and 34.1% (95% CI=20.1-50.6), respectively. There was no association between dialysis modality and depression score. The results revealed the reverse of association between depression score and the KDQOL-SF score. The beta coefficient (β) were -1.08 (95% CI -1.34 to -0.82; p-value<0.001) in overall patients, -0.96 [95% CI -1.30 to -0.63; p-value<0.001] in HD patients, and -1.28 [95% CI -1.73 to -0.82; p-value<0.001] in PD patients.
Conclusion: Depression is commonly revealed in dialysis patients and significantly associated with their quality of life. Healthcare providers need to pay attention to depression not merely emphasizing in physical treatments.
