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(P<0.05或P<0.01),观察组积极情绪状态(有力-好动)的得分显著低于对照组(P<0.05);观察组的简单反应时平均值慢于对照组(P<0.01),数字译码得分显著低于对照组(P<0.05),而错误打点数明显高于对照组(P<0.01),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。
Objective To investigate the effect of air-conditioned environment on the neurobehavioral function of workers. Methods The neurobehavioral functional tests were performed in 86 enterprises (observation group) and 102 non-air-conditioned environmental workers (control group) in Shenzhen, according to WHO-NCTB. Results The scores of the five negative emotional states (stress-anxiety, depression-depression, anger-hostility, fatigue-inertia, confusion- confusion) in the observation group were significantly (or significantly) higher than those in the control group ). The score of positive emotion state (vigorous-active) in the observation group was significantly lower than that of the control group (P <0.05). The average response time of the observation group was lower than that of the control group (P <0.01) In the control group (P <0.05), while the number of errors was significantly higher than the control group (P <0.01), the differences were statistically significant. Conclusion Air-conditioning environment may have some impact on the neurobehavioral function of workers, and it is necessary to take intervention measures on air-conditioning environment to promote the health of workers in air-conditioning environment.
