Prevalence of poor sleep quality in the Ethiopian population: a systematic review and meta-analysis

Abstract

Background: Only a limited amount of data is available from lower-income countries regarding the prevalence of poor quality of sleep. This meta-analysis of the scientific literature was performed to estimate the pooled prevalence of poor sleep quality in the Ethiopian population.

Methods: The study protocol followed was the Preferred Reporting of Items for Systematic Review and meta-analysis (PRISMA) statement.

Results: The nine studies which met the inclusion criteria provided data based on a total of 9103 participants who were studied at various health and academic institutions. The incidences of self-reported poor sleep quality ranged from 26 to 66.2%. The pooled estimate of poor sleep quality was 53%.There was a high prevalence of reported poor quality of sleep among younger subjects and among those who were studied in community (noninstitutional) settings.

Conclusion: The pooled prevalence of poor sleep quality is quite high among Ethiopians.
