Abstract: Objective To investigate the sleep disorders and their influencing factors in occupational pneumoconiosis patients. Methods A total of 1 176 occupational pneumoconiosis patients were selected by convenient sampling method to investigate their employer information, individual information, and pneumoconiosis related situation. Multivariate Logistic regression was used to explore the influencing factors of sleep disorders. Results A total of 994 （84.52%） patients with occupational pneumoconiosis had sleep disorders, and the median PSQI score was 12 （10, 14） points, including 13 （11, 15） points in the group with sleep disorders and 4 （3, 5） points in the group without sleep disorders （P < 0.01）. Compared with occupational pneumoconiosis patients without sleep disorders, the scores of subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disorders, sleep medication use, and daytime dysfunction in occupational pneumoconiosis patients with sleep disorders were significantly higher （all P < 0.01）. The results of multivariate Logistic regression analysis showed that marital status （OR _other =1.553）, health status （OR _general =0.473, OR _satisfactory =0.759）, quality of life （OR _better =0.110, OR _good =0.085）, and type of employer （OR _{private enterprise} =1.205） were associated with sleep disorders in occupational pneumoconiosis patients. Conclusions Occupational pneumoconiosis patients have high incidence of sleep disorders, which are related to marital status, health status, quality of life, and the type of employer.
