Prevalence and associated factors of depression among diabetic outpatients attending diabetic clinic at public hospitals in Eastern Ethiopia: A cross-sectional study

Abstract

Introduction: Depression is one of the most common comorbid psychiatric disorders among diabetic patients. Depression among diabetic people has led to poor treatment adherence, defective treatment outcomes, and consequently worsened quality of life. However, there is a limited study conducted to assess the magnitude and factors associated with depression among diabetic patients in Ethiopia including this study area. Objective: This study aimed to assess the prevalence and factors associated with depression among adult diabetic outpatients attending diabetic clinic in Eastern Ethiopia. Methods: An institution-based cross-sectional study was conducted among 407 adult diabetic outpatients on treatment in Ethiopia in 2020. Patient Health Questionnaire-9 was used to assess depression among randomly selected samples. Bivariate and multivariate logistic regression was fitted to identify factors associated with depression among diabetic outpatients. A p value less than 0.05 with a 95% confidence interval was considered statistically significant. Results: The overall prevalence of depression among diabetic outpatients was found to be 48.9% (95% confidence interval: 44.2%, 53.4%). Being female (adjusted odds ratio = 1.50, 95% confidence interval: 1.39, 2.73), Khat chewing (adjusted odds ratio = 1.88, 95% confidence interval: 1.22, 2.93), having poor and moderate social support (adjusted odds ratio = 1.79, 95% confidence interval: 1.07, 2.98 and adjusted odds ratio = 1.90, 95% confidence interval: 1.14, 3.17, respectively), taking both oral hypoglycemic agents and insulin medication (adjusted odds ratio = 1.33, 95% confidence interval: 1.13, 2.80) and duration of diabetes mellitus for more than 6 years (adjusted odds ratio = 5.40, 95% confidence interval: 3.42, 8.14) were significantly associated with depression. Conclusion: This study revealed a relatively high prevalence of depression in diabetic outpatients. A lesser level of social support, taking oral and insulin treatment regimes, longer duration of illness, using Khat, and being female were associated with depression among diabetic outpatients. Therefore, early screening and identification of such factors could help ameliorate some of the deleterious effects of depression in diabetic outpatients.
