医学生睡眠质量与焦虑抑郁情绪关系的探讨

目的 研究医学生睡眠质量与焦虑抑郁情绪的相关性，并对影响睡眠质量的有关因素进行探讨。方法 以匹慈堡睡眠质量指数（PSQI）、焦虑自评量表（SAS）、自评抑郁量表（SDS）为评价工具，采用分层整群抽样方法，调查某医学院1－4年级医学本科生睡眠障碍的发生率及分布特征。结果 医学生睡眠障碍的发生率为15．75％，男生（9．42％）女生（6．34％）间无显著性差异。19．18％的学生有抑郁情绪，男女生分别为10．10％和9．08％（P＜0．05），15．75％的学生存在焦虑，并且10．27％的学生焦虑、抑郁情绪并存。PSQI总分与SAS、SDS得分均呈显著正相关。回归分析表明，影响PSQI总分的因素依次为睡眠效率、睡眠障碍、入睡时间、睡眠质量、日间功能、催眠质量、日间功能、催眠药物、睡眠时间。结论 焦虑、抑郁情绪是影响医学生睡眠质量的重要因素，提高医学生的心理素质，增强其适应环境的能力，对于保持良好的健康状态是十分必要的。

Study of sleep quality and anxiety/depression in medical college students

Objective To research the correlation between sleep quality and anxiety/depression in medical college students, and explore other influencing factors of sleep quality. Methods Pittsburgh Sleep Quality Index (PSQI), Self Rating Anxiety Scale (SAS) and Self Rating Depression Scale (SDS) were applied to evaluate sleep quality, anxiety and depression. The prevalence and distribution character of sleep disorders were investigated in grade 1~4 medical college students by means of stratified cluster sampling. Results The prevalence of sleep disorders was 15.75%, boys 9.42%, girls 6.34%, there was no significant difference between sex. The prevalence was 15.75% and 19.18% for anxiety and depression, respectively, and 10.27% for both anxiety and depression. Analysis of correlation showed that there was positive correlation between the scores of PSQI and SAS/SDS. Multiple linear regression revealed that main influencing factors of PSQI scores were sleep efficiency, sleep disturbance, sleep latency, sleep quality, daytime dysfunction, use of sleep medication, sleep duration. Conclusion Anxiety and depression was the main influencing factors of sleep quality. Getting rid of them was an important measure of improving sleep quality.
