Table_1_Prevalence of Sleep Problems Among Chinese Medical Students: A Systematic Review and Meta-Analysis.xls

BackgroundSleep is a necessary physiological process, which is closely related to cognitive function, emotion, memory, endocrine balance, and immunity. The prevalence of sleep problems continues to rise in Chinese medical students, which has a potential influence on living and work.
ObjectiveThis study aimed to observe the prevalence of sleep problems among medical students in China.
MethodThe included cross-sectional studies on the prevalence of sleep problems of medical students in China were retrieved from PubMed, Embase, the Cochrane Database of Systematic Reviews, CNKI, and Wanfang database. An 11-item checklist recommended by the Agency for Healthcare Research and Quality was adopted to evaluate the methodological quality of the included studies. Software Stata 12.0, SPSS 26.0, and R were used to analyze the data. Registration: PROSPERO, CRD 42021237303.
ResultThe prevalence of sleep problems among Chinese medical students was 27.38%. The subgroup analysis showed significant differences in the prevalence of sleep problems among different regions, educational backgrounds, grades, and University types. The region, latitude, and gross domestic product (GDP) were significant heterogeneous sources of sleep problems. The prevalence is positively correlated with latitude and negatively correlated with GDP per capita. Regular screening and appropriate intervention are recommended for these mental health problems.

背景
睡眠是一项必需的生理过程，与认知功能、情绪、记忆、内分泌平衡及免疫功能密切相关。当前中国医学生睡眠问题的患病率持续攀升，对其生活与工作存在潜在影响。
目的
本研究旨在调研中国医学生睡眠问题的患病率。
方法
本研究从PubMed、Embase、Cochrane系统综述数据库（Cochrane Database of Systematic Reviews）、中国知网（CNKI）及万方数据库中，检索有关中国医学生睡眠问题患病率的横断面研究。采用美国医疗保健研究与质量局（Agency for Healthcare Research and Quality）推荐的11条目清单，对纳入研究的方法学质量进行评价。使用Stata 12.0、SPSS 26.0及R软件对数据进行分析。本研究已完成注册：PROSPERO，注册号CRD 42021237303。
结果
中国医学生睡眠问题的患病率为27.38%。亚组分析显示，不同地区、学历背景、年级及院校类型的医学生睡眠问题患病率存在显著差异。地区、纬度及国内生产总值（GDP）是睡眠问题患病率的显著异质性来源。患病率与纬度呈正相关，与人均国内生产总值呈负相关。针对此类心理健康问题，建议开展定期筛查并采取适当干预措施。
