The aim of this cross-sectional study was to assess the associations of burnout with cortisol parameters in 197 police officers from the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study (2010-2014). The Maslach Burnout Inventory-General Survey assessed depersonalization, exhaustion, and professional efficacy. Officers provided salivary cortisol samples collected upon awakening, and 15, 30, and 45 min thereafter as well as three additional samples at lunchtime, dinnertime, and bedtime. Total area under the curve with respect to increase (AUCW for waking and AUCD for diurnal), total area under the curve with respect to ground (AUCW for waking and AUCD for diurnal), and diurnal slope were determined and used in this study. Unadjusted and adjusted (age, sex, and race/ethnicity) associations were examined using linear regression. The mean age of the officers was 48 years and 72% were males. The depersonalization component of burnout was negatively associated with AUCD (β = -108.4; p = 0.036). Similarly, as exhaustion increased, AUCW (β = -9.58, p = 0.038), AUCD (β = -114.7, p = 0.029) and the diurnal slope (β = -0.000038; p = 0.017) decreased. The Professional efficacy was not associated with any of the cortisol parameters. These results suggest that certain characteristics of burnout may be associated with diminished cortisol secretion in this group of urban police officers. Our findings add to previous studies examining associations of burnout with the cortisol awakening response. Future longitudinal studies are needed to evaluate the temporal relationship between burnout and these cortisol parameters.
这项横断面研究的目的是评估来自布法罗心脏代谢职业警察压力（BCOPS）研究（2010 - 2014年）的197名警察中职业倦怠与皮质醇参数之间的关联。马氏职业倦怠量表 - 一般调查评估了去个性化、耗竭和职业效能。警察提供了醒来时采集的唾液皮质醇样本，以及之后15分钟、30分钟和45分钟时的样本，以及午餐时间、晚餐时间和就寝时间的另外三个样本。确定了觉醒时曲线下面积增加量（觉醒时的AUCW和昼夜的AUCD）、相对于基线的曲线下总面积（觉醒时的AUCW和昼夜的AUCD）以及昼夜斜率，并用于本研究。使用线性回归检验未调整和调整后（年龄、性别和种族/民族）的关联。警察的平均年龄为48岁，72%为男性。职业倦怠的去个性化成分与AUCD呈负相关（β = -108.4；p = 0.036）。同样，随着耗竭程度增加，AUCW（β = -9.58，p = 0.038）、AUCD（β = -114.7，p = 0.029）和昼夜斜率（β = -0.000038；p = 0.017）降低。职业效能与任何皮质醇参数均无关联。这些结果表明，职业倦怠的某些特征可能与这组城市警察的皮质醇分泌减少有关。我们的研究结果补充了之前关于职业倦怠与皮质醇觉醒反应关联的研究。未来需要进行纵向研究来评估职业倦怠与这些皮质醇参数之间的时间关系。
