: Fatigue is prevalent among hospital nurses and has been linked to medical errors and decreased patient safety. However, little is known regarding the relationship between occupational physical activity, sedentary behavior, and fatigue. : To assess the impact of 12-hour shifts on nurses' fatigue and its relationship to occupational physical activity and sedentary behavior. : Prospective-cohort study design Midwestern trauma one academic medical center : A total of 80 registered nurses working 12-hour day and night shifts participated in this study and completed momentary measures of fatigue (texting, aim one). Only 52 participants were included in aim two analyses (included activity monitoring, aim two). : Occupational patterns of momentary fatigue was measured via ecological momentary assessments. Occupational physical activity and sedentary behaviors (e.g., step count, time spent sitting, standing, and walking) were measured for 14 continuous days using the ActivPAL3 micro activity monitor. Mixed models were used to examine the effects of shift type and time within a shift on occupational fatigue. General estimation equations were used to examine the relationship between time spent sitting, standing, and walking on fatigue. : Regardless of shift type, nurses exhibited a significant rise in fatigue; however, the rise was greater during night shifts compared to day shifts. Walking was positively associated with fatigue during day shifts, and negatively associated with fatigue during night shifts. : The rise in fatigue was greater among nurses working night shifts compared to day shifts, which could place them at greater risk for fatigue-related consequences. The relationship between walking and fatigue was moderated by shift-type. Nursing fatigue rises during 12-hour shifts, but the rise is greater for those working night shifts @DrRobertoBenzo.
疲劳在医院护士中很普遍，并且与医疗差错及患者安全降低有关。然而，关于职业体力活动、久坐行为与疲劳之间的关系，我们知之甚少。
评估12小时轮班对护士疲劳的影响及其与职业体力活动和久坐行为的关系。
前瞻性队列研究设计 中西部一级创伤学术医疗中心
共有80名从事12小时昼夜轮班的注册护士参与了本研究，并完成了疲劳的即时测量（短信调查，目标一）。目标二分析中仅纳入了52名参与者（包括活动监测，目标二）。
通过生态瞬时评估法测量瞬时疲劳的职业模式。使用ActivPAL3微型活动监测仪连续14天测量职业体力活动和久坐行为（如步数、坐着、站立和行走所花费的时间）。采用混合模型来检验轮班类型和轮班期间时间对职业疲劳的影响。使用广义估计方程来检验坐着、站立和行走所花费的时间与疲劳之间的关系。
无论轮班类型如何，护士的疲劳都显著增加；然而，与日班相比，夜班期间的增加幅度更大。白天上班时，行走与疲劳呈正相关，而夜间上班时，行走与疲劳呈负相关。
与日班护士相比，夜班护士的疲劳增加幅度更大，这可能使她们面临与疲劳相关后果的更大风险。行走与疲劳之间的关系受轮班类型的调节。护士在12小时轮班期间疲劳会增加，但夜班护士的增加幅度更大 @罗伯托·本佐医生
