Increased work stressors and decreased coping resources were correlated with the risk of sleep disturbances in both male and female workers. Reducing work stressors was found to be a protective factor against sleep disturbances in female workers. Coping resources had a modifying effect on the relationship between increased work stressors and sleep disturbances.
Study Objectives: We investigated whether changes in psychosocial work conditions affect the risk of sleep disturbances. Methods: Data pertaining to 2738 males and 1431 females were obtained from the Occupational Health Study of Petroleum Industry Workers (OHSPIW), a prospective cohort study of Chinese petroleum industry workers. The subjects were assessed with regard to work-related stressors, coping resources, and sleep disturbances at baseline (2012) and follow-up (2018). The variations in work stressors and coping resources, which were assessed using the Occupation Stress Inventory-Reviewed (OSI-R), were calculated. Sleep disturbances were evaluated with the self-reported Pittsburgh Sleep Quality Index (PSQI). Results: Increased work stressors (OR = 1.57, 95% CI = 1.24-1.99) and decreased coping resources (OR = 2.03, 95% CI = 1.48-2.78) were correlated with the likelihood of sleep disturbances in male and female workers. The primary risk factors included high role overload, increased responsibility, enhanced physical environment stressors, reduced self-care, and reduced rational coping. A reduction in work stressors was a protective factor against sleep disturbances in females only (OR = 0.63, 95% CI = 0.45-0.88). Coping resources had a modifying effect on the relationship between increased work stressors and sleep disturbances, with increased coping resources being associated with a lower odds of increased works stressors on sleep disturbances (OR = 1.29, 95% CI = 1.01-1.66) than decreased coping resources (OR = 3.60, 95% CI = 1.10-11.81). Conclusions: Changes in work stressors and coping resources have a significant influence on the risk of sleep disturbances. Our findings highlight important precautionary strategies to abate adverse psychosocial working environments and to strengthen coping resources to prevent work-related sleep disturbances.
