Prevalence of poor sleep quality in the Ethiopian population: a systematic review and meta-analysis
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.
The study protocol followed was the Preferred Reporting of Items for Systematic Review and meta-analysis (PRISMA) statement.
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.
The pooled prevalence of poor sleep quality is quite high among Ethiopians.
