Associated factors for depressive disorder in patients with end-stage renal disease treated with continuous ambulatory peritoneal dialysis

BACKGROUND: The aim of this study was to primarily determine factors associated with the depressive disorders in continuous ambulatory peritoneal dialysis (CAPD). METHODS: CAPD patients were recruited from the chronic kidney disease and CAPD Clinic of University Hospital. The stable CAPD patients for at least 3 months were included in the study. Sociodemographic data, renal conditions, and depressive disorder were evaluated. In addition to determining prevalence rate of depressive disorders, identification of factors associated with depressive disorders in CAPD patients were analyzed by using the multivariable logistic regression analysis with backward elimination procedure. RESULTS: The eligible participants were 108 patients. The study found that 11% of CAPD patients were diagnosed with depressive disorders including, minor depressive, dysthymic, and major depressive disorders. Additionally, the depressive disorders were associated with the duration between the diagnosis date of the end-stage renal disease (ESRD) and the initial treatment date (P=0.043). Accordingly, the ESRD patients diagnosed in <12 months had 3.57-fold higher risk of depressive disorders than the patients diagnosed after a long time. CONCLUSION: The rate of prevalence for depressive disorder is high in the CAPD patients. Additionally, the results of this study have shown the relationship between depressive disorder and time for diagnosis of ESRD. Specifically, the risk of depressive disorder increases when patients have a shorter duration between the dates of ESRD diagnosis and initial treatment. In addition to closed monitoring for those patients, the psychiatrists should be consulted for evaluation and treatment of depressive disorders for the suspected high risk patients.
