摘要
为阐明职业因素对列车乘务员神经系统功能的影响，探讨其发生原因，采用ＷＨＯ推荐的神经行为核心测试组合（ＮＣＴＢ）测试了４９名乘务员和４８名商店售货员的神经行为功能。结果除情感状态两组得分接近外（Ｐ＞０．０５），乘务员的其余各项行为测试值均明显差于对照组（Ｐ＜０．０５），其中简单反应时、手敏捷度、视觉保留、目标追踪Ⅱ与对照组比较，差异均有非常显著意义（Ｐ＜０．０１）。而长途列车乘务员的此种神经行为改变可能是倒班制度、车内噪声、二氧化碳等职业因素联合作用所致。
To expound the neurobehavioral influences of occupational factors on train attendants and the causative factors of the influences,the 49 attendants on long distance train and of 48 shop assistants as control group were measured by neurobehavioral core test battery(NCTB)recommended by WHO.The results showed that the train attendants were found to have significantly lower scores nearly in all behavioral tests(P<0 05) except the mood states,especially in simple reaction time,manual dexterity,visual retention,pursuit aiming test Ⅱ(P<0 01)compared with the control group.The changes detected in NCTB were considered the results of the combined effects of shift work,noise and CO 2 pullution in the train.
