Epidemiology of sleep disturbances among medical students in the Middle East and North Africa: a systematic review and meta-analysis
Abstract
Background: Sleep disturbances and their associated health issues are common among medical students. Despite this, the epidemiology of sleep disturbances among medical students in the Middle East and North Africa (MENA) region remains inadequately understood. Our objective was to synthesise the prevalence of sleep disturbances, including poor sleep quality, insufficient sleep duration, and excessive daytime sleepiness (EDS), and their variation in relation to academic performance and stress levels.
Methods: We performed a systematic review and meta-analysis. Two independent reviewers searched PubMed, Web of Science, Google Scholar, and the reference lists of relevant studies and reviews up to May 2024. We assessed the quality of the included studies using a risk of bias tool. We performed meta-analyses using random-effects models and used Cochran's Q between-subgroups statistic to test for differences across subgroups. We used the I2 statistic to assess the statistical heterogeneity. Further, we assessed the publication bias using Doi plots.
Results: We included 150 studies conducted in 16 MENA countries. We found that 59.1% of medical students suffer from poor sleep quality (Pittsburgh Sleep Quality Index mean (x̄) = 8.5; 95% confidence interval (CI) = 7.0-10.1), 59.8% have insufficient sleep duration (<7 hours per night) averaging 6.1 hours per night (95% CI = 5.4-6.9), and 38.4% experience EDS (Epworth Sleepiness Scale x̄ = 8.6; 95% CI = 8.0-9.1). Our results indicate a…
