Abstract：
To examine the mediation effect of burnout on the association between workaholism and tobacco and alcohol use. A total of 2199 workers from the French national electricity company fulfilled an online questionnaire. Smoking status, alcohol use disorder based on the Alcohol Use Disorders Identification Test-Consumption and workaholism based on the Work Addiction Risk Test were used as binary variables. Burnout was assessed as a continuous variable with the Copenhagen Burn-Out Inventory. Mediation analyses tested the direct effect of the associations between workaholism and each substance use, as well as the indirect effect passing through burnout, while adjusting for sociodemographic factors (gender, age, occupational grade and marital life), work stress using the effort-reward imbalance and overcommitment. When testing the mediation effect of burnout on the relation between workaholism and smoking, there was a significant direct effect of workaholism on smoking (Estimated effect of 0.27 [95% CI 0.01; 0.54]) and a significant indirect effect passing through burnout (Estimated effect of 0.09 [95% CI 0.02; 0.15]). When testing the mediation effect of burnout on the relation between workaholism and alcohol use, the direct effect of workaholism on alcohol use was not significant (Estimated effect of 0.21 [95% CI - 0.01; 0.44]) while the indirect effect passing through burnout was significant (Estimated effect of 0.10 [95% CI 0.04; 0.17]). Information and prevention regarding substance use should be reinforced among workers exposed to workaholism, especially if their workaholism led to a high level of burnout. Preventing the emergence of burnout among workaholics might have some benefits on their tobacco and alcohol use.
摘要：
目的研究职业倦怠对工作狂与烟草和酒精使用之间关系的中介作用。来自法国国家电力公司的2199名工人完成了在线调查问卷。吸烟状况,基于酒精使用障碍识别测试的酒精使用障碍-基于工作成瘾风险测试的消费和工作狂被用作二元变量。倦怠被评估为哥本哈根燃尽清单的连续变量。中介分析测试了工作狂与每种物质使用之间关联的直接影响，以及通过倦怠的间接影响，在调整社会人口因素(性别，年龄,职业等级和婚姻生活)，利用努力回报不平衡和过度承诺的工作压力。在测试倦怠对工作狂与吸烟之间关系的调解作用时，工作狂对吸烟有显著的直接影响(估计效应为0.27[95%CI0.01;0.54]),而通过倦怠有显著的间接影响(估计效应为0.09[95%CI0.02;0.15]).在测试倦怠对工作狂和饮酒之间关系的调解作用时，工作狂对饮酒的直接影响不显著(估计效应0.21[95%CI-0.01;0.44]),而通过倦怠的间接效应显著(估计效应0.10[95%CI0.04;0.17]).应在接触工作狂的工人中加强有关物质使用的信息和预防，特别是如果他们的工作狂导致了高度的倦怠。防止工作狂中出现倦怠可能对他们的烟草和酒精使用有一些好处。
