Abstract:
Objective To investigate impacts of shift work on the health-related quality of life among metro staff, and provide scientific basis for improving the health literacy of life of them.
Methods A total of 9 960 participants were the employees of a certain Metro Group Co., Ltd. in Wuhan of China. The questionnaires were used to collect information about demographic characteristics, occupational history and so on. Health-related quality of life was measured using the Mos 36-item Short Form Health Survey. Univariate and multivariate Logistic regression models were used to identify the associations between shift work and each domain of the SF-36 before and after gender stratification.
Results Among 9 960 employees, 68.6% were engaged in shift work. Among the subgroups of sex, occupation, passive smoking, physical activity, sleep quality and personal history of diseases, there were statistical significances of the physical and mental component scores of the SF-36 (P < 0.05). Multivariate Logistic regression analysis revealed that compared with the day shift staff, those with variable types of work shifts had a higher risk of low scores of general health status, health transition and social functioning. Compared with the day shift staff, the risk of low scores of physical functioning, role-physical, general health, health transition, vitality, social functioning and mental health presented a trend of fluctuation with the increase of shift work duration. Among male staff, the type of shift work was associated with each domain of the SF-36, but not in female staff.
Conclusion Shift work may be one of the most significant risk factors for health-related quality of life among metro staff, especially for male staff.
