It has been shown that the firefighter occupation leads to poor sleep quality and sleep architecture. Disturbed sleep in these occupations can lead to deleterious outcomes including a series of chronic diseases and illnesses such as CVD.

Purpose: The aims were (1) to quantify firefighters' sleep via polysomnography, (2) to identify differences between sleeping in the barracks versus sleeping at home, and (3) to compare firefighter data to age-matched normative data. We expected significant differences between both the home and the barrack conditions as well as significant differences when both conditions were compared to normative data.

Methods: 10 male firefighters completed 3 nights of polysomnography recordings (SleepProfiler^TM (Advanced Brain Monitoring, Carlsbad, CA, USA)) counterbalanced in both their own beds or barracks. A one-way rmANOVA statistical analysis was used to determine differences in sleep values with a Bonferroni correction if a significant difference was found with significance set at p < 0.05.

Results: Three important variables, cortical arousals (p < 0.05), autonomic activations (p < 0.01), and spindle duration (p < 0.01), had differences that were statistically significant between sleep at home or in the barracks, with sleep in the barracks being more disturbed. Clinical differences were also observed between the home and barrack conditions and all sleep results were more deleterious when compared to normative data.

Conclusions: The data demonstrates that firefighters show poor sleep quality and heavily impacted sleep architecture. This may be due to the effects of rotating shifts and occupational stress on the sleep-wake cycle. These results, when compared to age-matched normative data, show clinical manifestations of disturbed sleep in the firefighter population.

已经证明，消防员的职业会导致睡眠质量差和睡眠结构不良。这些职业中的睡眠紊乱可能导致一系列慢性疾病和病症，例如心血管疾病。

目的：

本研究的目的是（1）通过多导睡眠图量化消防员的睡眠情况；（2）识别在宿舍睡觉与在家睡觉之间的差异；（3）将消防员数据与同年龄匹配的正常数据进行比较。我们预期两者条件（即在家里和在宿舍中）之间存在显著差异，以及当这两种条件与正常数据相比较时也存在显著差异。

方法：

10名男性消防员完成了3晚多导睡眠图记录（SleepProfiler™ (Advanced Brain Monitoring, Carlsbad, CA, USA)），这些记录分别在家或在宿舍进行，并进行了交叉平衡设计。使用了一向重复测量方差分析（one-way rmANOVA）来确定睡眠值之间的差异，在显著差异的情况下应用Bonferroni校正，显著性水平设定为p < 0.05。

结果：

三个重要的变量——皮质唤醒(p<0.05)、自主激活(p<0.01)和纺锤体持续时间(p<0.01)，在在家睡觉和宿舍睡觉之间存在统计学上的显著差异，而在宿舍的睡眠更为紊乱。家庭环境与宿舍条件之间的临床差异也有所观察，并且所有睡眠结果与正常数据相比更加不利。

结论：

数据显示消防员表现出较差的睡眠质量和严重受损的睡眠结构。这可能是由于轮班制度和职业压力对睡眠-觉醒周期的影响所致。当与同年龄匹配的正常数据相比较时，这些结果显示出消防员群体中存在临床意义上的睡眠紊乱现象。
