The prevalence of cardiovascular disease in Ethiopia: a systematic review and meta-analysis of institutional and community-based studies.

Background: Worldwide cardiovascular disease is the major cause of disability and premature death. This is due to the ascending trend of consuming an unhealthy diet and obesity which increases the risk of hypertension and type 2 diabetes mellitus. Thus this study aimed to determine the pooled prevalence of the cardiovascular disease in Ethiopia.

Methods: Medline, Scopus, and Google Scholar search engines were accessed using medical subject heading (MeSH) terms for studies based in Ethiopia, from 2000 to 2018. However, studies done among a specific group of the population were excluded from the study. Data were extracted by one reviewer and then checked independently by a second reviewer. Studies were qualitatively synthesis in terms of design, quality, study population, outcomes, and result. Sub-group analysis and sensitivity tests were conducted to identify potential influences on the prevalence estimates. Quantitative results were pooled in a statistical meta-analysis using STATA version 14 software.

Result: Nine eligible cross-sectional studies were included in the analysis. The prevalence ranges from 1 to 20%. The pooled prevalence of cardiovascular disease (CVD) was 5% (95% CI: 3-8%). The prevalence was higher in the population who visits hospitals, 8% (95% CI: 4-12%) compared to the general population, 2% (95% CI: 1-5%). There was no significant difference in the overall prevalence of CVD between males and females.

Conclusion: The prevalence of cardiovascular disease was high. A higher prevalence of CVD was found among patients who visited health institutions than the general population and no observed significant sex difference in the prevalence.
