大学生的睡眠质量与抑郁、焦虑的关系

Relation of sleep quality to depression and anxiety in college students

目的:探讨大学生的睡眠质量与抑郁、焦虑症状严重程度的关系。方法:选取580名大学生,采用匹兹堡睡眠量表(PSQI)、抑郁自评量表(SDS)、焦虑自评量表测试(SAS)分别测查其睡眠质量以及抑郁、焦虑症状严重程度。SDS标准分≥53分为抑郁组,<53分为无抑郁组;SAS标准分≥50分为焦虑组,<50分为无焦虑组。结果:PSQI总分与SDS得分、SAS得分正相关(r=0.58、0.47,均P<0.01)。得到抑郁组39例、无抑郁组488例,焦虑组147例、无焦虑组380例;其中抑郁症状的大学生PSQI总分高于无抑郁症状者[(9.2±2.2)vs.(5.5±2.2),P<0.01],有焦虑症状的大学生PSQI总分高于无焦虑症状者[(7.2±2.6)vs.(5.3±2.1),P<0.01];且PSQI总分对SDS得分和SAS得分的主效应均有统计学意义(F=22.64、14.00,均P<0.01)。PSQI总分与SDS得分正向关联(β=0.58,P<0.01),对SDS得分解释率为33.4%;PSQI总分与SAS得分正向关联(β=0.47,P<0.01),对SAS得分的解释率为22.1%。结论:大学生睡眠质量是衡量抑郁、焦虑严重程度的重要指标。

Objective： To explore the relation of sleep quality to severity of depression and anxiety symptoms in college students. Methods： Totally 580 college students w ere selected. The Pittsburgh Sleep Quality Index（ PSQI）,Self-rating Depression Scale（ SDS） and Self-rating Anxiety Scale（ SAS） w ere adopted to measure the sleep quality and severity of depression and anxiety symptoms, respectively. The subjects, w hose SDS standards w ere more than or equal to 53,w ere divided into the depression group; less than 53,no depression group. And the subjects,w hose SAS standards w ere more than or equal to 50,w ere divided into the anxiety group; less than 50,no anxiety group. Results： The total score of PSQI w ere positively correlated w ith SDS score,SAS score（ r = 0. 579,r= 0. 472,P〈0. 01）. There w ere 39 cases of depression group,488 cases of no depression group,147 cases of anxiety group and 380 cases of no anxiety group. PSQI score of no depression group w as low er than that of depression group [（ 9. 2 ± 2. 2） vs.（ 5. 5 ± 2. 2）,P〈0. 01],and PSQI score of no anxiety group w as low er than that of anxiety group [（ 7. 2 ± 2. 6） vs.（ 5. 3 ± 2. 1）,P〈0. 01]. The main effect of PSQI score on the SDS score w as significant,and that on the SAS score（ F = 22. 64,14. 00; P〈0. 01）. Regression analysis show ed that,the total score of PSQI w as positively correlated w ith the score of SDS（ β = 0. 58,P〈0. 01）,and it explained the variation rate of33. 4%; the total score of PSQI w as positively correlated w ith the score of SAS（ β = 0. 47,P〈0. 01）,and it explained the variation rate of 22. 1%. Conclusion： It suggests that sleep quality is an important indicator to evaluate depression and anxiety,especially subjective sleep feeling.
