Abstract:
Background With the unprecedented development of aviation business, the work load and job burnout of airport employees are becoming more and more serious, and the impact on sleep quality needs to be addressed. Objective To explore the current situation of work load and sleep quality of airport employees, and whether job burnout plays a role in the relationship between the two variables. Methods During September 2023, a cross-sectional survey was conducted among employees of an airport in Hunan Province, and
1503 employees were surveyed. A basic information questionnaire, a work load measurement questionnaire, Maslach Burnout Inventory General Survey, and Pittsburgh Sleep Quality Index were used in the survey. Logistic regression was used to analyze the influencing factors of sleep quality. SPSS 25.0 PROCESS v4.1 plug-in was used to analyze the mediating effect of job burnout. Results A total of1503 questionnaires were distributed in this study, and1424 valid questionnaires were recovered, with a recovery rate of 94.7%. The rate of heavy work load was 50.0% (712/1424 ), the rate of job burnout was 74.6% (1062 /1424 ), and the rate of sleep disorders was 58.7% (836/1424 ). The results of logistic regression analysis showed that individuals with job burnout had a 1.734 times higher risk of reporting sleep disorders compared to those without job burnout (95% CI: 1.306, 2.302); compared to those with light work load, individuals with heavy work load have a higher risk of sleep disorders (OR=3.422, 95%CI: 2.639, 4.437). The results of mediating effect test indicated a work load-burnout-sleep quality pathway (P <0.001), with a mediation effect value of0.1052 (95%CI: 0.019, 0.067), accounting for 18.02% of the total effect. Conclusion The rate of job burnout and the rate of reporting poor sleep quality are high among airport employees, and job burnout plays a mediating role in the relationship between work load and sleep quality. Adopting measures to reduce work load and reduce burnout can improve the sleep quality of airport employees.
