急性轻、中度缺氧暴露对人情绪的影响

目的 研究急性轻、轻中度缺氧对人的情绪及焦虑状态的影响。方法 利用低压舱模拟３００ｍ（对照）、２８００ｍ、３６００ｍ、４４００ｍ高度缺氧暴露１ｈ，采用情绪状态问卷和状态－－焦虑问卷（Ｓ－ＡＩ），考察了１８名健康男性青年受试者的情绪变化。结果随着高度的增加，ＰＯＭＳ问中紧张－－焦虑（Ｔ），困惑－迷芒（Ｃ）和疲惫－惰性（Ｆ）消极情绪状态值及Ｓ－ＡＩ得分逐渐增加，而其中的积极情绪状态值即有力－－好动（Ｖ

Effects of Acute Mild and Moderate Hypoxia on Human Mood State

Objective To explore the effects of acute mild and moderate hypoxia on human mood state. Method The mood states of 18 healthy male volunteers were evaluated by self assessment questionnaires, profile of mood state (POMS) and state anxiety inventory (S AI) after random exposure to simulated altitude of 300 m (control),2800 m,3600 m and 4400 m for 1 h in a hypobaric chamber. Result The data at 300 m level were taken as the baseline control. The negative mood state factor points (tension, fatigue etc.) increased gradually as the altitude level increased while V (vigor-activity) points had a tendency to decrease (P<0.05 or P<0.01).No significant difference was found in the points of (D,A) even under exposure to 4400 m(P>0.05). At the early period of 2800 m exposure the tension points of POMS and S-AI scores were higher than those of control level (P<0.05) then dropped to baseline level when exposure to this altitude for 1 h. Conclusion Exposure to acute mild hypobaric hypoxia at 2800 m for 1 h has adverse effect on mood state of healthy person and the negative effect was further aggravated with the increment of altitude level.
