高原官兵精神运动警觉性测试与主观疲劳状态、睡眠质量的关系

The relationship between psychomotor vigilance test and subjective fatigue and sleep quality of officers or soldiers at high altitude

目的研究高原部队官兵精神运动警觉性测试(psychomotor vigilance test,PVT)与主观疲劳状态、睡眠质量的关系。方法选取2019年8月~9月空军军医大学唐都医院调查研究的73例高原某部官兵,完成PVT及疲劳严重程度量表(FSS)、失眠严重程度量表(ISI)、匹兹堡睡眠质量量表(PSQI)、Epworth嗜睡量表(ESS)、清晨夜晚型量表(MEQ)评估,根据主观疲劳严重程度分为疲劳组(31例)与非疲劳组(42例)。比较两组间PVT以及睡眠质量的差异,进一步研究PVT、疲劳与睡眠质量的关系。结果与非疲劳组相比,疲劳组PVT参数测试前主观疲劳、测试后主观疲劳、最大反应时间、大遗漏次数更差,整体PVT更差,PSQI、ESS、ISI分值更高,睡眠质量更差,差异有统计学意义(P<0.05)。PVT、主观疲劳感与睡眠质量相关。结论PVT可以作为检测疲劳状态的客观方法,改善高原部队官兵睡眠质量可能降低其主观、客观疲劳,提升部队战斗力。

Objective To investigate the relationship between psychomotor vigilance test and subjective fatigue and sleep quality of officers or soldiers at high altitude.Methods 73 officers or soldiers were included in this study.They all completed PVT and fatigue severity scale(FSS),insomnia severity scale(ISI),pittsburgh sleep quality scale(PSQI),epworth sleepiness scale(ESS),morningness-eveningness questionnaire(MEQ).We compared the differences of PVT and sleep quality between fatigue group and non-fatigue group,and further studied the relationship between PVT,subjective fatigue and sleep quality.Results Compared with the non-fatigue group,react pre mood,react post mood,maximum RT and major lapses of the PVT parameters which fatigue group did were worse(P<0.05),the overall PVT was worse;the scores of PSQI,ESS and ISI were higher(P<0.05),and the sleep quality was worse.PVT and subjective fatigue may be related to sleep quality.Conclusion PVT can be used as an objective method to detect fatigue state.Improving the sleep quality of officers and soldiers at high altitude can reduce the risk of their subjective and objective fatigue and enhance the combat effectiveness of troops.
