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.
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.
10 male firefighters completed 3 nights of polysomnography recordings (SleepProfiler (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 < 0.05.
Three important variables, cortical arousals ( < 0.05), autonomic activations ( < 0.01), and spindle duration ( < 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.
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.
（1）通过多导睡眠图量化消防员的睡眠，（2）确定在军营和家中睡眠的差异，以及（3）将消防员的数据与年龄匹配的正常数据进行比较。我们预计两种条件（在家和在军营）之间以及将这两种条件与正常数据进行比较时，都会存在显著差异。
10 名男性消防员在家中或军营各完成了 3 晚的多导睡眠图记录（SleepProfiler（Advanced Brain Monitoring，加利福尼亚州卡尔斯巴德））。采用单因素重复测量方差分析统计方法，如果发现有显著差异，则采用 Bonferroni 校正进行睡眠值差异的分析，显著性水平设置为<0.05。
有 3 个重要变量（皮层唤醒<0.05）、自主激活<0.01）和纺锤波持续时间<0.01）在在家或在军营睡眠时存在统计学差异，军营睡眠的干扰更大。在家和军营条件之间也观察到了临床差异，与正常数据相比，所有睡眠结果都更具危害性。
数据表明，消防员的睡眠质量较差，睡眠结构受到严重影响。这可能是由于轮班和职业压力对睡眠-觉醒周期的影响。与年龄匹配的正常数据相比，这些结果显示了消防员人群中睡眠障碍的临床表现。
