lence of sleep disturbance in Korean university students and provide evidence to develop appropriate strategies for improving sleep disturbance. Methods: Pooled prevalence of sleep disturbance in Korean university students was assessed using PubMed, CINAHL, Research Information Sharing Service, National Assembly Library, Korean studies Information Service System, and Korea Citation Index databases. A total of 1,843 studies were retrieved from the literature search, and 14 studies were included in the analysis. Statistical analysis was performed using comprehensive meta-analysis software. Results: The overall pooled prevalence was 48.9% (95% confidence interval [CI], 41.6-56.3%). Subgroup analyses revealed that the pooled prevalence rates were 59.2% (95% CI, 38.8-50.7%) in the Pittsburgh Sleep Quality Index (PSQI)-based and 26.0% (95% CI, 19.5-33.9%) in non-PSQI-based studies, 23.2% (95% CI, 15.6-33.1%) in low-quality and 56.9% (95% CI, 49.3-64.2%) in moderate-quality studies, 35.6% (95% CI, 33.4-37.8%) in studies published before 2010 and 51.4% (95% CI, 42.9-59.8%) in studies published since 2011. Conclusions: The prevalence of sleep disturbance is higher in university students. Therefore, further studies are needed to identify sleep problems of university students and gain future-oriented insights to develop mediation strategies.
