Abstract:

Objective To analyze the status and related influencing factors of occupational stress and sleep disorders of workers in a ferrous metallurgical manufacturing enterprise in Wuhu City,and provide a basis for the prevention and control of occupational stress and sleep disturbances in staff. Methods From May to June 2025,a cluster sampling method was used to select 846 employees from an enterprise in Wuhu City as the study subjects. The concise occupational stress questionnaire,effort-reward imbalance(ERI) questionnaire,and Pittsburgh sleep quality index(PSQI) were employed to investigate the status of job-demand control(JDC) model occupational stress,effort-reward imbalance(ERI) model occupational stress,and sleep disorders among the enterprise employees,and the data were analyzed. Results The prevalence rates of JDC mode occupational stress,ERI mode occupational stress and sleep disorders were 48.23%(408/846),45.98%(389/846) and 41.37%(350/846),respectively. In ERI and JDC models,the prevalence of sleep disorders in the high occupational stress group was higher than that in the low occupational stress group(P<0.05). In the JDC model,monthly income of 5 000-<7 000 yuan was the influencing factor of occupational stress(P<0.05). In the ERI model,college and above enterprise workers,heavy physical labor and length of service were the influencing factors of occupational stress(all P<0.05). Work intensity,JDC and ERI mode,occupational stress,length of service and educational level were the influencing factors of sleep disorders(all P<0.05). Conclusion The detection rate of occupational stress and sleep disorders of 846 employees is high in a ferrous metallurgical manufacturing enterprise in Wuhu City. Monthly income of JDC model,education level of ERI model,work intensity and length of service are the influencing factors of occupational stress. Education level,length of service,work intensity and occupational stress are the influencing factors of sleep disorders.
