Abstract
BACKGROUND: Patients with chronic medical and mental illnesses are more vulnerable to poor sleep quality. However, there is little aggregated evidence about poor sleep quality among this population and its determinants in Ethiopia. This study was aimed at assessing the pooled prevalence of sleep quality and its determinants among patients with chronic diseases in Ethiopia. METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to write this review. Primary articles were retrieved from PubMed, PsycINFO, Hinari, ScienceDirect, African Journal Online (AJOL), and Google Scholar databases. A random-effects model was applied for analysis. I (2), Cochran's, and tau(2) were checked to determine the degree of heterogeneity between the included studies. Egger's test and sensitivity analysis were conducted to check publication bias. RESULTS: The pooled prevalence of poor sleep quality among patients with chronic medical and mental illnesses was 53.12% (95% CI: 47.66, 58.58). Eight factors were associated with poor sleep quality: advanced age (POR = 1.04, 95% CI: 1.02, 1.07), female sex (POR = 2.95, 95% CI: 2.21, 3.93), social support (POR = 2.62, 95% CI: 1.90, 3.61), substance use (POR = 1.76, 95% CI: 1.51, 2.04), anxiety symptoms (POR = 2.92, 95% CI: 2.40, 3.56), comorbidity (POR: 2.47, 95% CI: 1.83, 3.33), sleep hygiene practice (POR: 2.86, 95% CI: 2.02, 4.04), and depression symptoms (POR = 3.73, 95% CI: 2.96, 4.69). CONCLUSION AND RECOMMENDATION: More than half of patients with chronic diseases experienced poor sleep quality. Poor sleep quality was connected with advanced age, female sex, substance use, having comorbidity, inadequate social support and sleep hygiene practices, anxiety, and depression symptoms. Substance use should be restricted, and patients with chronic mental and medical illnesses should be counseled to avoid substance use. Moreover, special focus should be given to female patients, patients with other comorbid conditions, elderly individuals, and those who have poor sleep hygiene and social support. Lastly, patients with chronic medical and mental illnesses should be screened for anxiety and depression symptoms.
