Abstract

This study investigates the relationship between sleep quality, study stress, and mental health among medical undergraduates in Anhui Province. Utilizing the Pittsburgh Sleep Quality Index (PSQI) and Depression-Anxiety-Stress Scale-21 (DASS-21), data from 550 students were analyzed. Findings reveal that heavy academic burdens, including high weekly course loads and examination stress, significantly impact sleep quality and mental health. Students attending 45–50 classes/week had a significantly higher PSQI score (5.41 ± 3.25) compared to those with lighter loads (e.g., 30–35 classes: 4.61 ± 2.75, p = 0.050; Table 8). Although no significant association was found between caffeine and alcohol consumption and mental health, lifestyle factors such as exercise frequency and interpersonal relationships showed notable effects. These results underline the need for targeted interventions, including stress management programs and healthy lifestyle promotion, to enhance student well-being.

安徽省医学本科生睡眠质量及其相关因素：学业压力、心理健康和生活方式因素的横断面研究

本研究旨在探讨安徽省医学本科生睡眠质量、学习压力与心理健康的关系。利用匹兹堡睡眠质量指数（PSQI）和抑郁-焦虑-压力量表-21 (DASS-21)，分析了550名学生的数据。研究结果显示，沉重的学业负担，包括每周高课程负担和考试压力，会显著影响睡眠质量和心理健康。每周上45-50节课的学生PSQI得分（5.41±3.25）显著高于负荷较轻的学生(例如，30-35节课：4.61±2.75,p = 0.050；表8)。虽然咖啡因和酒精摄入与心理健康之间没有明显的联系，但生活方式因素，如运动频率和人际关系，却有显著的影响。这些结果强调需要有针对性的干预措施，包括压力管理方案和促进健康的生活方式，以提高学生的福祉。
