Magnitude of depression and its associated factors among patients with diabetes mellitus at public hospitals in Southwest Ethiopia, 2021

Depression is the third-leading cause of disability measured in terms of disability-adjusted life-years. When depression coexists with diabetes mellitus, it is associated with major health consequences and results in poor health outcomes, decreased quality of life, lost productivity and increased risk of death. The current study aimed to assess the magnitude of depression and its associated factors among adult patients with diabetes mellitus attending follow-up at the public hospitals of Buno Bedele zone, Southwest Ethiopia. A multi-centre cross-sectional study was done among people living with diabetes mellitus at an outpatient clinic of Buno Bedele zone hospitals. The study period was from April to May 2021. A systematic random sampling technique was used to select the study participants. Data were collected using a structured questionnaire. Depression was assessed by the Patient Health Questionnaire-9. Patient Health Questionnaire-9 is a validated tool to assess depression with sensitivity 86% and specificity 67%. The collected data were cleaned, edited, and entered into epi-data version 3.1, and analysed using SPSS version 24. Logistic regression analysis was employed to identify factors associated with depression occurrence. A p value of 0.05 was considered statistically significant. A total of 310 study participants were included in this study. Among study participants, 41.6% fulfilled the criteria for depression. Variables significantly associated with depression were female gender [AOR: 2.26, 95% CI (1.30, 3.95)], duration of diabetes greater than 5 years [AOR: 2.68, 95% CI (1.57, 4.56)], poor social support [AOR: 2.46, 95% CI (1.10, 5.49)], moderate social support [AOR: 2.63, 95% CI (1.34, 5.16)], current alcohol consumption [AOR: 3.55, 95% CI (1.20, 10.52)] and previous alcohol consumption [AOR = 2.81, 95% CI (1.40, 5.60)]. According to this study, depression is relatively common among diabetic individuals. Being a female, having diabetes for a long time, having poor social support, using alcohol now and in the past were factors that substantially linked to depression. Healthcare professionals should consider screening for depression using the Patient Health Questionnaire-9 or other validated tools in all diabetic patients, especially in those who are at higher risk.
