旅途精神病的危险因素及其相关分析

Risk factors of travelling psychosis

作者对长途列车旅行中发生旅途精神病的危险因素及其与生理指标、心理指标、临床症状的相关性进行了调查。结果表明：①发病者多是农民、文化程度较低，女性亦占一定比例；②车厢ＣＯ２浓度、有无座位、乘车时间、性格内外向、乘车次数是与旅途精神病发生有关的危险因素；③相关分析进一步对危险因素与生理指标、心理状态、临床症状的关系予以揭示。本研究提示，旅途精神病可能是易感人群对长途旅行这一应激的极端表现，车厢的ＣＯ２浓度亦起重要作用。

Objective:To study the risk factors of travelling psychosis.Method:72 patients with travelling psychosis were compared with 95 normal controls who took long journey by train. Demographic data, details of travelling, psychophysiological profile and clinical features were examined.Results:1)There were more females,more peasants and lower education in the patient than controlled group. 2)Five other risk factors were identified which included high concentration of carbon dioxide in the train carriage,having no seats,long travelling time, introverted personality and inexperience with long distance travel. 3)Some association was found between the risk factors, psychophysiological index and clinical manifestations.Discussion:It is suggested that travelling psychosis is a response in susceptible persons to stresses of long distance travel and the high concentration of carbon dioxide in the train carriage plays an important role.
