Objective To analyze the influencing factors of sleep disorders and the relationship between working hours per week and sleep disorders among employees in oil field enterprises in Gansu Province. Methods The employees of oil field enterprises in Gansu Province were investigated from January to June 2022. The basic information and sleep quality data of 2 178 subjects were collected by self-made questionnaire combined with Pittsburgh Sleep Quality Index scale. The normal sleep group and sleep disorder group were matched according to 1:1 by propensity score matching (PSM). Univariate analysis and multivariate logistic regression analysis were performed to analyze the influencing factors of sleep disorder. Restricted cubic spline (RCS) model was used to analyze the dose-response relationship between working hours per week and sleep disorder. Results The detection rate of sleep disorders among oil field workers in Gansu Province was 45.68%. In total 957 pairs of propensity scores were matched successfully, and the baseline data of the two groups were basically balanced after matching. Multivariate logistic regression analysis showed that hypertension (OR=1.507, 95%CI: 1.124-2.022), diabetes mellitus (OR=1.743, 95%CI: 1.020-2.980), length of service of 10 to 19 years (OR=1.325, 95%CI: 1.021-1.719), length of service of 20 to 29 years (OR=1.437, 95%CI: 1.071-1.927), length of service ≥ 30 years (OR=1.581, 95%CI: 1.095-2.282), weekly working hours of 49 to 55 hours (OR=1.381, 95%CI:1.026-1.859), working hours ≥ 56 hours per week (OR=1.999, 95%CI: 1.551-2.575), and work injury (OR=1.479, 95%CI: 1.114-1.962) were the risk factors of sleep disorder, while physical exercise (OR=0.694, 95%CI: 0.573-0.839) was the protective factor. The results of restricted cubic spline model showed that there was a non-linear dose-response relationship between the working hours per week and sleep disorders. When the working hour per week exceeded 40 hours, the risk of sleep disorders increased. Conclusion The sleep problem of oil field workers should be paid attention to. Enterprises should urge workers to develop healthy living habits, improve working environment, arrange working hours reasonably, and improve sleep quality, to reduce the risk of sleep disorders.
