Questionnaire Survey The Troop's Sleep Quality And Cognitive Function Of Different Times Coming Into Tibet In Hypoxic Environment

【Objective】Through the questionaire survey of the army personnel who came into Tibet in the different time reffering to Pittsburgh Sleep Quality Index(PSQI)and the Wechsler Adult Intelligence Scale(WAIS-RC),the sleep quality,intelligence quotient,memory condition and the relevance between quality of sleep and high level nerve function about the army person who came into Tibet in different time in environment of high altitude anoxia were acquainted.【Methods】According to different time of the officers and soldiers came into Tibetan plateau,the two companies that have 148 persons were radomly selected as objects.The objects were divided into two groups,groupⅠ(adaptation):serving more than a year in Tibet,there are 73 persons in total;groupⅡ(acclimatization period):total of 75 persons who served in Tibet not more than three months.Carried out a questionaire survey to the above groups by the Pittsburgh sleep Quality Index Scale and Wechsler Intelligence Scale.【Results】1,PSQI total score was taken as a judgement of sleep quality standards.PSQI of the persons who served in Tibet more than one year was 7.58±4.17,but PSQI of the perons who served in Tibet less than three months was 9.60±3.22.And the scores of various factors affecting sleep quality about acclimatization period groups were more than those of adaptation groups, the different scores between the two groups besides drug hypnosis had statistical significance.2,The various constituents of the cognition questionnaire scores of persons who served in Tibet less than three months were lower than ones of who served in Tibet more than one year,and the cognitive questionnaire scores between these two groups were statistically significant differences.3,The research about IQ,memory state of different PSQI scores in the officers and soliders showed that cognitive scores of different sleep quality of persons stationing in Tibet more than one year were no significant difference(p＞0.05);but those of persons stationing in Tibet less than three months were statistically significant difference (p＜0.05).That is,the higher the PSQI scores the lower the cognitive scale scores are.4,For officers and soliders stationing in Tibet,strong negative correlations existed between each factor score of sleep quality(besides medicine hypnosis)and ten factors scoresof IQ and memory condition(p＜0.05).【Conclusion】1,In the environment of high altitude anoxia,the sleep quality of the officers and soliders who stationed in Tibet less than three months was more inferior than that of persons who stationed more than one year,it showed sleep difficulties,daytime dysfunction and bad subjective sleep.So improving sleep quality of officers and soliders stationed in Tibet should be taken from these aspects.2,In the environment of high altitude anoxia,the cognitive function test scores of the officers and soliders who stationed in Tibet less than three months was lower than those of persons who stationed more than one year.Then,through the peacetime training,increasing proficiency so that cognitive level of them could be enhanced.3,After analysing the sleep quality and cognitive function about officers and soliders who stationed less than three months and more one year in Tibet,sleep quality of acclimatization period persons direct influenced their cognition level.Looking from entire sleep quality and the cognition level of officers and soldiers stationed in Tibet, there were negative correlation between each factor(besides medicine hypnosis)of sleep quality and each factor of cognition level.Therefore,their cognition level could be enhanced through improving sleep quality of officers and soldiers stationed in Tibet,especially officers and soldiers in acclimatization period.
