目的抑郁症状与睡眠不足密切相关，医学生抑郁症状发生率较高。睡前拖延症被认为是睡眠不足的一个新的、重要的预测指标。然而，睡前拖延症和抑郁症状之间是否存在关联尚不清楚。本研究旨在探讨就寝拖延症对医学生抑郁症状的影响。方法共邀请419名中国医学生参与本研究，最终纳入401名受试者，平均年龄19.48岁，年龄范围17 ~ 23岁。采用贝克抑郁量表（BDI-II）和就寝拖延量表（BPS）分别对抑郁症状和就寝拖延进行评估。结果中国医学生抑郁症状患病率为26.9%。抑郁组的平均BPS得分明显高于非抑郁组。二元逻辑回归分析发现，睡前拖延症是抑郁症状流行的独立因素。进一步的相关分析和多元线性回归分析表明，BDI得分与无抑郁学生的BPS得分呈显著正相关，而BDI得分与有抑郁的男生呈显著正相关。结论抑郁症状在中国医学生中越来越普遍，与就寝拖延症独立相关。特别是，抑郁症状的严重程度与睡前拖延症的增加呈正相关，而只有在抑郁状态下才与性相关。
PurposeDepression symptoms are closely related to inadequate sleep and are experienced by medical students at an increased rate. Bedtime procrastination is considered a new, important predictor of sleep deficiency. However, whether there is a correlation between bedtime procrastination and depression symptoms remains unclear. This study aimed to examine the impact of bedtime procrastination on depression symptoms among medical students.MethodsA total of 419 Chinese medical students were invited to participate in this study, and 401 participants (mean age, 19.48 years; range, 17–23 years) were included in the final statistical analysis. Depression symptoms and bedtime procrastination were assessed using the Beck Depression Inventory-II (BDI-II) and the Bedtime Procrastination Scale (BPS), respectively.ResultsThe prevalence of depression symptoms in Chinese medical students was 26.9%. The mean BPS scores were significantly higher in the depressed group than in the non-depressed group. Binary logistic regression analysis identified that bedtime procrastination was an independent contributor to the prevalence of depression symptoms. Further correlation and multiple linear regression analyses demonstrated that the BDI scores were significantly and positively associated with the BPS scores in students without depression, while the BDI scores correlated with male students experiencing depression.ConclusionsDepression symptoms, which become more prevalent among Chinese medical students, are found to independently associate with bedtime procrastination. In particular, the severity of depression symptoms shows a positive correlation with increased bedtime procrastination before developing into depression, and it shows correlation with sex only in a state of depression.
