大学生高海拔驻留时间对睡眠质量的影响

Sleep quality varied along with the time of residence at high altitude

目的:考察高海拔缺氧对睡眠质量影响的时间效应,以及焦虑、抑郁情绪对睡眠质量可能存在的影响。方法:采用序列追踪设计,使用匹兹堡睡眠质量量表(PSQI)、焦虑自评量表(SAS)、抑郁自评量表(SDS),追踪测试首次进入高海拔地区(3650米)大学生的睡眠质量和焦虑、抑郁水平,3次测试分别完成于驻留7天、3个月和1年。结果:对于实验组而言,3次测量的PSQI总分存在显著差异(F=3.62,P<0.05)。进一步多重比较发现,居住满1年时的PSQI总分显著低于3个月时的PSQI总分(P<0.05),其他两两间差异均不显著(P>0.05);实验组3次测量的焦虑总分与对应的3个PSQI总分相关均不显著(P>0.05);实验组3次测量的抑郁总分与对应的3个PSQI总分相关均不显著(P>0.05)。结论:高海拔驻留时间影响睡眠质量,但随着驻留时间的延长,睡眠质量会得到恢复和改善。没有发现焦虑、抑郁情绪对高海拔缺氧环境下的睡眠质量存在影响的证据。

Objective:To investigate the time effect of high altitude hypoxia on sleep quality and the possible influence of anxiety and depression on sleep quality.Methods:In this study,we used sequence tracking design.At the same time,the PSQI,SAS and SDS scales were used as measuring tools.On this basis,data collected in three times(one week,three months and one year at high altitude area,respectively)were analyzed of 30 college students entering the high altitude area(3650 m)for the first time.Results:For the experimental group,there was a significant difference in the total score of PSQI measured three times(F=3.62,P<0.05).Further multiple comparisons revealed that the total PSQI score at the end of 1 year was significantly lower than that at the end of 3 months(P<0.05),there was no significant difference between the other two groups(P>0.05);The total anxiety scores measured three times in the experimental group were not significantly correlated with the corresponding three PSQI scores(P>0.05);The total depression scores measured three times in the experimental group were not significantly correlated with the corresponding three PSQI scores(P>0.05).Conclusion:High altitude residence time affects sleep quality,but sleep quality will be restored and improved with the prolongation of residence time.No evidence is found that anxiety and depression affect the quality of sleep in high altitude hypoxia environment.
