空运进驻高原急性高原病症状因子分析

Factor analysis on symptoms of acute mountain sickness (AMS) entered alititude by air

目的：探讨经空运进驻高原时，发生急性高原病（AMS）的主要症状之间的潜在联系。方法：采用随机抽样方法抽取307人作为高原研究组，运用症状调查表调查急性高原病（AMS）的主要症状及评分，运用WinSAS6．11统计软件对症状及评分进行因子分析。结果：提取的三个公因子分别为脑型AMS公因子、肺型AMS公因子和轻型AMS公因子，其解释脑型AMS公因子的主要症状为：恶心、呕吐、食欲减退、头痛；解释肺型AMS公因子的主要症状为：气急、胸闷、乏力、呼吸困难；解释轻型AMS公因子的主要症状为：心悸、烦燥不安、睡眠障碍、咳嗽。结论：运用因子分析加斜交旋转提取的三个公因子模型能够较好的解释空运进驻高原发生的各型AMS。

0bjective: To study potential interrelation of symptoms of acute mountain sick-ness (AMS) entered altitude by air. Meth0ds: 3O7 subjects as alititude group were divided by ran-dom sampling, Symptoms Questionaire was used to investigate the mostly AMS common symp-toms of alititude group entered altitude and the most1y symptoms scoring of AMS was analysied byfactor analysied. Results: Three factors extracted by principal factor analysis and obliquely rotationwere cerebral AMS, Respiratory AMS and gently AMS respectively. The leading symptoms ofcerebral AMS were nauses、vomiting、lose of appetitie. headache; the leading symptoms of respira-tory AMS were short of breathe. chest pain. feel tired, hard of breathe and gently AMS were heartfast . feel irritable. cann't sleep. cough . Conclusion: It indicated that three factors pattern extractedby principle fator analysis and obliquely rotation could better interpretability all type of AMS en-tered alititude by air.
