title: [Occupational stress in assembly line workers in electronics manufacturing service and related influencing factors].
abstract: Objective:To investigate occupational stress in assembly line workers in electronics manu-facturing service (EMS) and related influencing factors.Methods:From June to October, 2015, a cross-sectional survey was performed for 5 944 assembly line workers in EMS (observation group) and 6 270 workers from other posts (non-assembly line workers and management personnel; control group) using the self-made questionnaire for basic information, job demand-control (JDC) model questionnaire, and effort-reward imbalance (ERI) model questionnaire to collect respondents' basic information and occupational stress.Results:The observation group had significantly lower work autonomy, social support, and work reward scores than the control group (2.72 ± 0.63/3.64 ± 0.68/4.06 ± 0.80vs3.00 ± 0.67/3.83 ± 0.68/4.24 ± 0.75,t=23.53, 15.41, and 12.70, allP<0.05) , as well as significantly higher work effort and job involvement scores than the control group (2.34±0.78/2.48±0.78vs2.21±0.80/2.33±0.77,t=-9.08 and-10.90, bothP<0.05). The observation group had significantly higher proportions of workers with occupational stress determined by JDC and ERI models than the control group (64.5%/12.7%vs52.6%/9.9%, χ2=182.26 and 23.41, bothP<0.05). Female sex, migrant workers, working time >60 hours/week, and sleeping time <7 hours/day were major risk factors for occupational stress in JDC model; education background of Bachelor's degree or above, working time >60 hours/week, and sleeping time<7 hours/day were major risk factors for occupational stress in ERI model, while female sex and a high monthly income reduced the risk of occupational stress in ERI model.Conclusion:Assembly line workers in EMS are a relatively vulnerable group and have a high degree of occupational stress. Working time >60 hours/week and sleeping time <7 hours/day are major risk factors for occupational stress.
