贵州省医学研究生睡眠质量与负性情绪的相关性分析

Correlation analysis between sleep quality and negative emotions in medical graduate students in Guizhou province

目的:了解贵州省医学研究生的睡眠质量与负性情绪现状,分析睡眠质量的影响因素及其与负性情绪的关系。方法:使用分层随机整群抽样,抽取贵州省1630名医学研究生,采用匹兹堡睡眠质量指数量表(PSQI)、抑郁-焦虑-压力自评量表(DASS-21)开展问卷调查,运用Spearman相关和Logistic回归分析探讨睡眠与负性情绪的关系。结果:1630名医学研究生中男485名(29.75%),女1145名(70.25%);汉族1301人(79.82%),少数民族329人(20.18%);平均年龄为(25.00±2.60)岁。医学研究生的PSQI总分为(4.98±3.01)分,睡眠障碍检出率为18.71%,压力、焦虑、抑郁检出率分别为14.79%、29.69%、28.77%。Spearman相关分析显示睡眠质量及各因子得分与负性情绪得分均呈正相关(均r>0,P<0.01);Logistic回归分析显示自评健康差(OR=3.57,95%CI:2.16~5.92)、压力(OR=2.54,95%CI:1.75~3.69)、焦虑(OR=1.52,95%CI:1.02~2.26)、抑郁(OR=2.41,95%CI:1.62~3.60)是医学研究生睡眠质量的危险因素。结论:医学研究生睡眠质量得分与负性情绪得分呈正相关,高校应采取有针对性措施加强研究生心理健康教育,改善研究生负性情绪,提高研究生睡眠质量。

Objective:To investigate the current status of sleep quality and negative emotions of medical postgraduates in Guizhou,and to analyze the influencing factors of sleep quality and its relationship with negative emotions.Methods:A total of 1630 medical postgraduates in Guizhou province were selected by stratified random cluster sampling.The Pittsburgh Sleep Quality Index(PSQI)and Depression Anxiety Stress Self-Rating Scale(DASS-21)were used to conduct a questionnaire survey.Spearman correlation analysis and Logistic regression analysis were used to explore the relationship between sleep and negative emotions.Results:Among the 1630 medical postgraduates,485(29.75%)were males and 1145(70.25%)were females;1301(79.82%)were Han nationality and 329(20.18%)were ethnic minorities,and the average age was(25.00±2.60)years old.The total PSQI score of medical postgraduates was(4.98±3.01),and the detection rate of sleep disorders was 18.71%.The detection rates of stress,anxiety and depression were 14.79%,29.69%and 28.77%,respectively.Correlation analysis showed that sleep quality and each factor score were positively correlated with negative emotions(all r>0,P<0.01).Logistic regression results showed that poor self-rated health(OR=3.57,95%CI:2.16-5.92),stress(OR=2.54,95%CI:1.75-3.69),anxiety(OR=1.52,95%CI:1.02-2.26)and depression(OR=2.41,95%CI:1.62-3.60)were risk factors for sleep quality of medical postgraduates.Conclusion:The sleep quality score of medical postgraduates is positively correlated with the score of negative emotions.Colleges and universities should take targeted measures to strengthen the mental health education of postgraduates,improve the negative emotions of postgraduates,and improve the sleep quality of postgraduates.
