Systematic review and meta-analysis on the prevalence and associated factors of depression among hypertensive patients in Ethiopia

Abstract

Background Identifying individuals at increased risk for depression allows for earlier intervention and treatment, ultimately leading to better outcomes and potentially preventing severe symptoms. However, to date, no systematic reviews or meta-analyses have estimated the prevalence of depression among hypertensive patients. Thus, this review was initiated to determine the prevalence and factors associated with depression among patients with hypertension in Ethiopia. Methods Multiple databases, such as PubMed, African Journals Online, the Cochrane Library, and Google Scholar, were used to ensure wider coverage of relevant studies. The data extracted from Microsoft Excel were imported into STATA version 11 (Stata Corp LLC, TX, USA) for further analysis. The pooled prevalence of depression was estimated using a random effects model. To evaluate statistical heterogeneity, the Cochrane Q test and I2 statistic were used. Results The random effect model indicated that the pooled prevalence of depression in 12 studies conducted in Ethiopia was 32.43% (95% CI: 25.18, 39.67%). Being female (POR = 2.41; 95% CI: 1.89, 3.07, I2 = 17.7%, P = 0.302), having comorbid illnesses (POR = 3.80; 95% CI: 2.09, 6.90, I2 = 81%, P = 0.005), having poor blood pressure control (POR = 3.58; 95% CI: 2.51, 5.12, I2 = 0.0%, P = 0.716), having a family history of depression (POR = 3.43; 95% CI: 1.98, 5.96, I2 = 62.6%, P = 0.069), being single (POR = 2.30; 95% CI: 1.35, 3.99, I2 = 48.0%, P = 0.146) and having poor social support (POR = 4.24; 95% CI: 1.29, 13.98, I2 = 95.8%, P<0.001) were positively associated with depression among hypertensive patients. Conclusion Overall, the results of our review showed that depression affects a significant number of Ethiopians who have hypertension. Being female, being single, having comorbidities, having poor blood pressure control, having a family history of depression, and having poor social support were factors associated with depression among patients with hypertension. For those who are depressed, improving the psycho-behavioral treatment linkage with the psychiatric unit can result in improved clinical outcomes.
