Background & Aims: Coal mining is notoriously challenging and hazardous, often leading to detrimental impacts on workers’ mental health, including anxiety, stress, depression, and sleep disorders. This study evaluates the sleep quality of coal miners in Mongolia and identifies the factors influencing it.
Methods: A cross-sectional survey of 329 mine workers, including 200 shift workers (60.8%) and 129-day workers (39.2%), was conducted in October 2023. Participants’ stress levels and sleep quality were measured using the standardized Perceived Stress Scale and Pittsburgh Sleep Quality Index, alongside anthropometric assessments.
Results: The results revealed that significant sleep disturbances affected 51.2% of day workers and 56.0% of shift workers. Multiple logistic regression analysis showed that among shift workers, moderate-to-high stress levels (AOR＝2.672, 95% CI 1.268-5.628), being female (AOR＝7.377, 95% CI 2.178-24.980), and having 11 years of work experience (AOR＝2.257, 95% CI 1.164-4.377) were significantly associated with sleep disturbances. No significant factors were identified for day workers.
Conclusions: The study concludes that mitigating stress is crucial for improving the sleep quality of coal miners, particularly shift workers. Addressing these issues can enhance overall well-being and safety in the mining industry.
