Very little is known about the biologic predictors of the occupational burnout in firefighters. The aim of this study was to characterize testosterone profile of active firefighters and quantify its association with three domains of the occupational burnout.
We enrolled 100 firefighters (median age 28 (interquartile range (IQR) 9.8) years with 5 (IQR 9) years in service) of three fire departments in Almaty, Kazakhstan. Demographics, smoking status, health-related quality of life (HRQL) and burnout scores of Maslach Burnout Inventory were assessed using a questionnaire, while total blood testosterone was measured in venous blood. Logistic regression models were used to quantify the association of blood testosterone with each burnout domain in the adjusted for confounders models.
The median blood testosterone level was 14 (IQR 3.5) nmol/l and was only predicted by age (beta - 0.14, p < 0.01, 79% power). There were no differences in blood testosterone levels between occupational groups (Group 1 (firefighters), 14.6 (IQR 3.4); Group 2 (fire truck drivers), 14.7 (IQR 5.6); Group 3 (shift commanders, division heads, department managers and engineers), 14 (IQR 4.1) nmol/l, Kruskal-Wallis p = 0.32) or departments. Testosterone could not predict EX or CY, but had a negative association with PE score reflecting more burnout (odds ratio 1.18 (95% confidence interval 1.01;1.38)), adjusted for age, mental component of HRQL and education.
Firefighters with higher testosterone may develop burnout in PE earlier, and this should be considered for proper work placement within the rescue system.
关于消防员职业倦怠的生物学预测因素，人们了解甚少。本研究的目的是描述在职消防员的睾酮水平特征，并量化其与职业倦怠三个维度的关联。
我们招募了哈萨克斯坦阿拉木图三个消防部门的100名消防员（中位年龄28岁（四分位间距（IQR）9.8），服役5年（IQR 9））。使用问卷评估人口统计学、吸烟状况、健康相关生活质量（HRQL）和马氏职业倦怠量表的倦怠得分，同时测定静脉血中的总血睾酮水平。在调整混杂因素的模型中，使用逻辑回归模型量化血睾酮与每个倦怠维度的关联。
血睾酮水平中位数为14（IQR 3.5）nmol/l，仅由年龄预测（β -0.14，p <0.01，检验效能79%）。不同职业组（第1组（消防员），14.6（IQR 3.4）；第2组（消防车司机），14.7（IQR 5.6）；第3组（轮值指挥官、部门主管、部门经理和工程师），14（IQR 4.1）nmol/l，Kruskal-Wallis检验p = 0.32）或不同部门之间的血睾酮水平无差异。睾酮不能预测情感耗竭（EX）或去人格化（CY），但与反映更高倦怠程度的个人成就感（PE）得分呈负相关（优势比1.18（95%置信区间1.01；1.38）），在调整年龄、HRQL的心理成分和教育程度后。
睾酮水平较高的消防员可能更早出现个人成就感维度的倦怠，在救援系统内进行合理的工作安排时应考虑这一点。
