Objectives: Studies show significant variability in adolescent sleep quality prevalence, likely due to differing definitions of adolescence and the use of various assessment questionnaires. This meta-analysis aimed to determine the prevalence of poor sleep quality using the Pittsburgh Sleep Quality Index (PSQI) among adolescents aged 10 to 19 years. Materials 95% CI = 23%-38%) when compared to other regions. No significant differences were observed in the impact of other factors, including gender, development level, sample size, survey time, PSQI cut-off, response rate, and quality score, on the overall heterogeneity of the analyzed data. Conclusion: The present study is a first for providing a comprehensive overview of the problem of poor sleep quality among adolescents, with a large sample size and consistent definitions and measurements.
