: Recent research indicates that shift work is associated with neurocognitive function. However, studies that examine the association between shift work and neurocognitive function in firefighters have not yet been performed. We examined the effect of shift work on neurocognitive function in firefighters by measuring and comparing neurocognitive function before and after night shift. : 352 firefighters from eight fire stations in South Korea were included in this study. We performed neurocognitive function test using central nervous system vital signs (CNSVS) during daytime work and on the next day after night work. We performed paired -tests to assess differences between neurocognitive function before and after night work. We also compared neurocognitive function in insomnia and depression. We used a general linear model to analyze the associations between shiftwork schedule and the changes in neurocognitive function. : The neurocognitive function significantly decreased in six domains (composite memory, verbal memory, visual memory, complex attention, psychomotor speed, and motor speed) as did the neurocognitive index on the next day after night work compared with during day work. These decreased domains were the same following night work regardless of the type of shift work. : Night work in firefighters may cause neurocognitive decline.
最近的研究表明，轮班工作与神经认知功能有关。然而，尚未有研究考察轮班工作与消防员神经认知功能之间的关系。我们通过测量和比较轮班前后的神经认知功能来检验轮班工作对消防员神经认知功能的影响。
本研究纳入了韩国 8 个消防站的 352 名消防员。我们在白天工作时和夜班后的第二天使用中枢神经系统生命体征（CNSVS）进行神经认知功能测试。我们进行了配对检验，以评估夜班前后神经认知功能的差异。我们还比较了失眠和抑郁患者的神经认知功能。我们使用一般线性模型分析轮班时间表与神经认知功能变化之间的关联。
与白天工作相比，夜班后第二天的神经认知功能在六个领域（综合记忆、言语记忆、视觉记忆、复杂注意力、心理运动速度和运动速度）以及神经认知指数显著下降。无论轮班类型如何，夜班后都会出现相同的下降领域。
消防员的夜班工作可能导致神经认知能力下降。
