Major depressive disorder and suicidal behavior among urban dwelling Ethiopian adult outpatients at a general hospital

- Our study results show that MDD and suicidal behavior are highly prevalent among urban-dwelling Ethiopian adults.
- The lifetime prevalence of major depressive disorder was 18%.
- The prevalence of suicidal behavior was 15.2%.
- Results may help inform future preventive efforts among groups identified as at risk for MDD and suicidal behavior.

BackgroundWe sought to evaluate the prevalence and correlates of major depressive disorder (MDD) and suicidal behavior among urban dwelling Ethiopian adults.MethodsThis was a cross-sectional study of 1097 outpatient adults (≥18 years of age) in a major hospital in Addis Ababa, Ethiopia. Sociodemographic and lifestyle characteristics were collected via structured interviews. MDD and suicidal behavior were assessed using the Composite International Diagnostic Interview (CIDI) among all study participants. Multivariable logistic regression models were fitted to estimate odds ratios (OR) and 95% confidence intervals (95% CI).ResultsPrevalence estimates for lifetime and 12-month MDD were 18.0% and 6.7%, respectively. The prevalence of suicidal behavior during the previous year (i.e., suicidal ideation, plan or attempt) was 15.2% with approximately 4% having reported attempts. Overall, women were more likely to report suicidal behavior (17.8%) than men (11.3%). MDD odds were 1.53-fold higher among women as compared with men (aOR=1.53, 95% CI 1.05-2.23). Lifetime MDD was significantly associated with age, sex, marital status, and self-reported physical health. Participants reporting poor mental health had approximately 3-fold increased odds of MDD (OR=2.93; 95%CI: 1.05-2.23); those between 35 and 44 years old (aOR=1.92; 95%CI: 1.06-3.49) and those older than 55 years (aOR=2.54; 95%CI: 1.16-5.57) had higher odds of MDD. Similarly suicidal behavior was significantly associated with sex, marital status, and self-reported physical and mental health.LimitationsThis cross-sectional study utilized self-reported data from outpatients. Causality cannot be inferred, and results may not be fully generalizable.ConclusionsOverall results show that MDD and suicidal behavior are highly prevalent among urban-dwelling Ethiopian adults. Women and middle-age adults constitute a high-risk group and may therefore benefit from targeted interventions.
