The aim of this study was to investigate the prevalence and severity of firefighter sleep quality across department shift schedules.
Sleep quality was assessed using a Pittsburgh Sleep Quality Index in a sample of 109 male career firefighters from six fire departments in three Southwestern US states. The three shift schedules studied were 24on/48off, 48on/96off, and Kelly.
Seventy-three percent of firefighters report poor sleep quality. The 24on/48off shift schedule is associated with the best sleep quality and Kelly is associated with the worst sleep quality. Firefighters working second jobs report significantly poorer sleep quality than those who do not.
Shift schedules that disrupt normal circadian rhythms more result in poorer sleep quality, which can lead to less effective emergency response and increased risk to firefighter health and safety.
本研究旨在调查不同部门轮班时间表下消防员睡眠质量的患病率及严重程度。
采用匹兹堡睡眠质量指数对美国西南部三个州六个消防部门的109名男性职业消防员进行睡眠质量评估。研究的三种轮班时间表分别是24小时在岗/48小时休息、48小时在岗/96小时休息以及凯利制。
73%的消防员报告睡眠质量差。24小时在岗/48小时休息的轮班时间表与最佳睡眠质量相关，而凯利制与最差睡眠质量相关。从事第二份工作的消防员报告的睡眠质量明显比不从事第二份工作的消防员差。
更扰乱正常昼夜节律的轮班时间表会导致睡眠质量更差，这可能会导致应急反应效率降低，并增加消防员健康和安全风险。
