空调作业环境对神经行为功能的影响

目的探讨空调环境对作业工人神经行为功能的影响。方法运用WHO推荐的神经行为功能测试组合(WHO-NCTB)对深圳市某企业密闭空调环境作业工人86名(观察组)及非空调环境作业工人102名(对照组)进行了神经行为功能测试。结果观察组5项消极情绪状况(紧张-焦虑、忧郁-沮丧、愤怒-敌意、疲劳-惰性、困惑-迷茫)的得分均显著(或非常显著)高于对照组(P0.05或P0.01),观察组积极情绪状态(有力-好动)的得分显著低于对照组(P0.05);观察组的简单反应时平均值慢于对照组(P0.01),数字译码得分显著低于对照组(P0.05),而错误打点数明显高于对照组(P0.01),差异均有统计学意义。结论空调环境可对作业工人神经行为功能产生一定的影响,有必要对空调环境采取干预措施,以促进空调环境作业工人的身体健康。

Effect of air-conditioned environment on neurobehavioral function of workers

Objective]To study the effects of air-conditioned environment on neurobehavioral function in workers. Methods]Following the neurobehavioral core test battery(NCTB) recommended by WHO,86 workers who worked in enclosed air-conditioned environment(observation group) and 102 worked in non-air-conditioned environment(control group)were studied on their neurobehavioral function in a factory of Shenzhen City. Results]The scores of negative mood state(stress-anxiety,sullen-depression,anger-hostility,fatigue-inertia,obfuscation-confusion) of workers in the observation group were significantly(or extremely significantly) higher than those in the control group(P<0.05 or P<0.01),while the scores of positive mood state(powerful-active)was significantly lower than that in the control group(P<0.05).The average of the simple reaction time in the observation group was significantly longer than that in the control group(P<0.01).The scores of digit symbol test in the observation group was significantly lower than that in the control group(P<0.05).The number of error hitting points in the observation group was significantly higher than that of control group(P<0.01). Conclusion]Air-conditioned environment has a certain adverse effect on neurobehavioral function of workers.It is necessary to carry out the intervened measures in air-conditioned environment to raise body health of workers.
