Abstract:
Objective To explore the effect of occupational stress on sleep quality and health-related productivity loss, and the mediating effect of sleep quality on occupational stress and health-related productivity loss in programmers of an Internet enterprise, in order to suggest intervention strategies for reducing health-related productivity loss.
Methods In April 2021, a cross-sectional survey on occupational stress, sleep quality and health-related productivity was carried out among programmers in an Internet enterprise in Shanghai, with a work content questionnaire, a Pittsburgh sleep quality index questionnaire, and a work productivity and impaired activity questionnaire. Complete questionnaires were obtained from 251 individuals (response rate: 89.6%). Multiple regression analysis was used to explore the effects of occupational stress and sleep quality on health-related productivity loss of programmers in the Internet enterprise, and the mediating effect of sleep quality on occupational stress and health-related productivity loss was tested by mediating effect analysis.
Results Occupational stress and sleep quality were important influencing factors of health-related productivity loss, a significant positive correlation was observed (P<0.01), and occupational stress was positively correlated with sleep quality problems (P<0.01). Sleep quality had a positive mediating effect on occupational stress and health-related productivity loss. The mediating effect on the occupational stress and reduced work efficiency, invalid working hours, sickness absenteeism, and total health-related productivity loss was 11.97%, 10.14%, 34.60% and 12.52%, respectively.
Conclusion There is a close correlation between occupational stress, sleep quality and health-related productivity of programmers in the Internet enterprise, and sleep quality plays a partial mediating role between occupational stress and health-related productivity. A series of sleep quality improvement plans should be designed to reduce the impact of occupational stress on the loss of health-related productivity, and to improve health-related productivity in Internet enterprises.
