【摘要】：目的:比较长期生活在中海拔地区藏、汉族健康青年男性睡眠结构、睡眠质量及夜间氧饱和度等指标,探讨两个民族在中海拔地区睡眠状况的差异,从睡眠的角度研究藏、汉族对中海拔高原的适应机制。方法:选择青海大学医学院(青海西宁,海拔为2262m,大气压=77.35k Pa,1mm Hg=0.133k Pa)大三及以上年级的健康男性学生,汉族33名,平均年龄(22.3±1.2)岁,藏族34名,平均年龄(22.2±1.6)岁,进行多导睡眠监测,根据2007版美国睡眠医学学会睡眠分阶规则分析睡眠监测结果,比较两组睡眠结构、睡眠质量及氧饱和度等指标。结果:藏族组的微觉醒指数明显低于汉族组[(15.2±5.7)次/h vs.(18.3±6.2)次/h,P0.05],且藏族组由气流受限引发的微觉醒也较少(P0.05);夜间脉氧饱和度95%占总睡眠时间百分比明显高于汉族组[5.5(1.0,14.5)%vs.1.8(0.3,5.2)%,P0.05]。其他指标包括总睡眠时间、睡眠效率、非快动眼睡眠(1、2、3期)潜伏期、快动眼睡眠潜伏期、睡眠分期、氧饱和度及呼吸暂停低通气指数等均无明显差异(均P0.05)。结论:中度海拔对藏、汉族睡眠的影响均较小,但中海拔地区藏族微觉醒明显少于汉族且能维持更高的氧饱和度,提示藏族较汉族有更好的睡眠。
[Abstract]:Objective: to compare the sleep structure, sleep quality and nocturnal oxygen saturation of young healthy males living at middle altitude for a long time, and to explore the difference of sleep status between the two nationalities at middle altitude, and to study Tibet from the point of view of sleep. The adaptation mechanism of Han nationality to middle altitude plateau. Methods: a total of 33 male healthy male students with an average age of 22. 3 卤1. 2 years old and 34 Tibetans with an average age of 22. 2 卤1. 6 years old were enrolled from the College of Medicine of Qinghai University (Xining, Qinghai, 2262 m above sea level, atmospheric pressure 77.35 k Pa1 mm Hg=0.133k Pa1). The polysomnography was performed on 33 male students with an average age of 22. 3 卤1. 2 years, and 34 Tibetans with an average age of 22. 2 卤1. 6 years. According to the sleep order rules of the American Academy of Sleep Medicine 2007, the results of sleep monitoring were analyzed, and the sleep structure, sleep quality and oxygen saturation were compared between the two groups. Results: the microarousal index in the Tibetan group was significantly lower than that in the Han nationality group [15.2 卤5.7rh vs.(18.3 卤6.2], and the arousal induced by airflow limitation in the Tibetan group was lower than that in the Han nationality group (P 0.05), and the percentage of nocturnal oxygen saturation 95% in the total sleep time was significantly higher than that in the Han nationality group (5.51.014.5vs.1.80.35.2p0.05). There was no significant difference in total sleep time, sleep efficiency, non-REM sleep latency, sleep stage, oxygen saturation and apnea hypopnea index (all P 0.05). Conclusion: moderate altitude has little effect on sleep in Tibetan and Han nationality, but the microarousal of Tibetan at middle altitude is obviously less than that of Han nationality and can maintain higher oxygen saturation, suggesting that Tibetan has better sleep than Han nationality.
