轮班和职业紧张交互作用对电力企业员工职业倦怠的影响
Interaction between shift work and occupational stress on occupational burnout among em-ployees in power companies
摘要
Abstract
[Background]The power industry is characterized by typical shift work systems,with 24-hour uninterrupted work demands,high intensity and high standard job characteristics,as well as emergent task pressure,which exposes employees to the long-term dual pressure of shift work and occupational stress and may lead to occupational burnout.It not only endangers the physical and mental health of employees,but also threaten the safe and stable operation of the power system. [Objective]To explore the impact of shift work and occupational stress,as well as their potential interaction,on occupational burnout among employees in power enterprises. [Methods]From November 2024 to April 2025,cluster sampling was used to select 1 378 workers from two power companies in Fuzhou.A self-designed questionnaire,the Effort-Reward Imbalance model,and the Maslach Burnout Inventory were used to investigate the participants'general information,shift work patterns,occupational stress,and occupational burnout.Statistical analysis was conducted using SPSS 19.0 software.Chi-square test was employed for intergroup comparison.Logistic regression was used to examine the associations between shift work,occupational stress,and job burnout.The multiplicative interaction and additive interaction between shift work and occupational stress on occupational burnout were evaluated. [Results]A total of 1 378 questionnaires were distributed,and 1 113 were valid questionnaires,with an effective rate of 80.77%.Among the participants,37.92%were engaged in shift work,the positive rate of occupational stress was 29.83%,and the positive rate of occupa-tional burnout was 55.80%.The logistic regression analysis showed that after adjusting for confounding factors,the risks of occupational burnout in the non-shift x occupational stress group and the shift x occupational stress group were 1.59 times(95%CI:1.12,2.27;P=0.01)and 4.07 times(95%CI:2.56,6.45;P<0.01)higher than that in the non-shift x non-occupational stress group.A multiplicative interaction(shift work and occupational stress b=0.75,P=0.01,OR=2.12,95%CI:1.18,3.80)and an additive interaction(relative excess risk ratio=2.24,95%CI:0.54,3.94;attributable fraction=0.55,95%CI:0.32,0.78;interaction index=3.71,95%CI:1.47,9.40)between shift work and occupational stress on job burnout were identified. [Conclusion]Shift work and occupational stress are risk factors for occupational burnout among employees in power enterprises,and there is a synergistic interaction between these two factors in terms of their impact on occupational burnout.关键词
