目的研究急性轻、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300 m( 对照) 、2800 m 、3600 m 、4400 m 高度缺氧暴露1 h ,采用情绪状态问卷(POMS) 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 问卷中紧张—焦虑(T) ,困惑—迷茫(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) 得分则依此下降( P< 0 .05 或P< 0 .01) ,但POMS 中愤怒- 敌意(A) 和抑郁- 沮丧(D) 的得分并无显著变化( P> 0 .05) 。2800 m 急性暴露的即刻,紧张- 焦虑(T) 和S- AI得分显著高于对照水平( P< 0 .05) ,而暴露1 h 后又下降至地面水平。结论急性轻、中度缺氧暴露1 h 在2800 m 高度水平即对人的情绪及心境产生负面影响,随着高度的增加上述影响进一步加重。
Objective To study the effects of acute mild hypoxia on human emotion and anxiety. Methods The hypoxia chamber was used to simulate the hypoxia exposure of 300 m (control), 2800 m, 3600 m and 4400 m for 1 h. The emotional state questionnaire (POMS) and state-anxiety questionnaire (S- AI) Emotional changes in young subjects. Results As the height increased, the values of negative emotional state (T-anxiety), confusion-confusion (C) and fatigue-inertia (F) negative emotions and S-AI scores gradually increased in the POMS questionnaire. The positive emotional state values (P <0.05 or P <0.01), but there was no significant change in POMS scores of anger-hostility (A) and depression-depression (P > 0 .05). Immediate, stress-anxiety (T) and S-AI scores at 2800 m acute exposure were significantly higher (P <0 .05) than control levels, but dropped to ground level 1 h after exposure. Conclusion The acute and moderate hypoxia exposure at 1 h at 2800 m has a negative impact on human emotion and mood, which further aggravates with the height increase.
