24 h完全睡眠剥夺对青年男性主观情绪体验及疲劳感的影响

Effects of 24 hours of total sleep deprivation on subjective emotional feelings and fatigue in young males

目的探索24 h完全睡眠剥夺对青年男性主观情绪体验及疲劳感的变化规律。方法采用自身前后对照研究设计,招募20名健康男性大学生完成24 h完全睡眠剥夺,采用简明心境量表(POMS)和视觉类比量表(VAS)评定主观情绪体验及疲劳感程度。试验开始于07∶00并收集基线值,之后在11∶00、15∶00、19∶00、23∶00、次日01∶00、03∶00及07∶00分别进行评估,共8次。结果与基线值相比,POMS中紧张-焦虑(P<0.01)、抑郁-沮丧(P<0.05)、愤怒-敌意(P<0.01)、疲倦-迟钝(P<0.01)和混乱-迷惑(P<0.01)得分增加,精力-活力(P<0.01)得分下降;VAS中焦虑(P>0.05)、易怒(P>0.05)、神经质(P>0.05)及多话(P>0.05)得分在睡眠剥夺期间无明显变化,警觉(P<0.01)、精力充沛(P<0.01)得分持续下降,自信(P<0.01)得分下降,嗜睡程度(P<0.01)得分增加。结论青年男性在睡眠剥夺8 h即出现主观情绪变化,12 h主观疲劳感开始明显增加。主观评定方法对于评价完全睡眠剥夺中青年男性主观情绪体验及疲劳感是敏感的,但相对于情绪体验,疲劳感的变化趋势更加稳定。

Objective To explore the effects of 24 h total sleep deprivation(TSD)on subjective emotional feelings and fatigue in young men.Methods In this before⁃after study,20 healthy undergraduates were recruited to complete 24 h TSD.The Profile of Mood States(POMS)and Visual Analogue Scale(VAS)were used to evaluate subjective emotional feelings and fatigue.The study began at 07∶00(Baseline),POMS and VAS were completed at 11∶00,15∶00,19∶00,23∶00 on the first day and at 01∶00,03∶00 and 07∶00 on the second day,8 times in all.Results Compared with baseline,tension⁃anxiety(P<0.01),depression⁃dejection(P<0.05),anger⁃hostility(P<0.01),fatigue⁃inertia(P<0.01),confu⁃sion⁃bewilderment(P<0.01)of POMS increased significantly during 24 h TSD,while vigor⁃activity(P<0.01)decreased significantly.Anxiety(P>0.05),irritability(P>0.05),nervousness(P>0.05)and talkativeness(P>0.05)in VAS remained stable,but vigilance(P<0.01)and vigor(P<0.01)decreased persistently.Confidence(P<0.01)decreased while sleepiness(P<0.01)increased during 24 h TSD.Conclusion Subjective emotional feelings can deteriorate at 8 h and fatigue increases at 12 h in TSD for young men.The subjective assessment method is sensitive for evaluation of subjective emotional feelings and fatigue during 24 h total sleep deprivation.However,the sensation of fatigue tends to be more stable than subjective emotional feelings.
