Sleep disruption is a growing concern among military personnel. Very little is known, however, regarding sleep and associated factors in military members serving in combat environments. We sought to quantify the prevalence of sleep disruption among military personnel serving in a combat zone during Operation Enduring Freedom, utilizing a cross-sectional survey of active duty and reserve U.S. Navy personnel in the Afghanistan combat theater (N = 6,118). Survey sleep measures included total hours of sleep per day, total hours of sleep needed to feel well rested, difficulty falling asleep, and difficulty staying asleep. Other reported outcomes included accidents related to the mission. Participants reported an average of 5.9 hours of sleep per day despite needing an average of 6.8 hours to feel well rested. Fifty-seven percent reported insufficient sleep, and this interacted with mission type. Sleep disruption was associated with number of prior deployments, as well as total number of months in a combat zone. Further, those who reported less sleep were more likely to report causing an accident or error that affected the mission. This article documents basic sleep metrics and deployment-related correlates of sleep disruption among military members in a combat zone.
睡眠中断在军事人员中日益受到关注。然而，对于在战斗环境中服役的军事人员的睡眠及相关因素，我们所知甚少。我们试图通过对在阿富汗战区的现役和后备役美国海军人员（N = 6,118）进行横断面调查，来量化在持久自由行动期间在战斗区服役的军事人员中睡眠中断的患病率。调查的睡眠指标包括每天的总睡眠时间、感觉休息良好所需的总睡眠时间、入睡困难和睡眠维持困难。其他报告的结果包括与任务相关的事故。尽管平均需要6.8小时才能感觉休息良好，但参与者报告平均每天睡眠5.9小时。57%的人报告睡眠不足，且这与任务类型有关。睡眠中断与先前部署的次数以及在战斗区的总月数有关。此外，报告睡眠时间较少的人更有可能报告导致影响任务的事故或失误。本文记录了战斗区军事人员睡眠中断的基本睡眠指标以及与部署相关的关联因素。
