Prevalence of depression and its associated factors among patients of chronic kidney disease in a public tertiary care hospital in India: A cross-sectional study

Chronic kidney disease (CKD) patients are at high risk of depressive disorders because of considerable psychological stress due to physical and social changes brought on by disease. The aim of this study is to assess the prevalence of depression in patients with CKD and the factors affecting it at a public tertiary care hospital. This cross-sectional study was carried out at the renal clinic of a tertiary care hospital. Data on 612 patients diagnosed with CKD from September 2014 to April 2016 was obtained. Nine-item Patient Health Questionnaire from PRIME-MD was used to assess the depression. Of all the patients, 55.9% had no depression. Mild depression was found to affect 28.4% of the patients followed by moderate depression, moderately severe, and severe depression (11.8%, 3.8%, and 0.8%, respectively). According to multiple logistic regression, the occurrence of depression was significantly higher with age below 60 years [odds ratio (OR) 1.6, 0.8-2.7; P<0.05], male gender (OR 1.3, 0.9-3.1; P<0.05), no treatment funding (OR 2.6, 1.2-4.5; P<0.05), education less than grade 12 (OR1.3, 1.3-3.2; P<0.05), monthly income ≤INR 20,000 (OR 1.6, 1.1-3.6; P<0.05), CKD stage V (OR 1.3, 1.02.9; P <0.05), Patients on hemodialysis (hD) (OR 2.6, 1.2-4.5; P<0.05), comorbidities ≥3 (OR 1.7, 1.1-2.9; P<0.05), overweight (OR 2.5, 1.3-2.9; P<0.05), and duration of CKD >2 (OR 2.2, 1.3-4.3; P<0.05). About 44% of the patients were found to have depression. Patients' age, gender, body mass index, treatment funding, education status, income, CKD duration and stage, HD status, and comorbidities were found to be significant factors affecting depression.
