Objective To explore the status and influencing factors of occupational stress among assembly-line workers in labor-intensive enterprises.
Methods A total of 1 420 assembly-line workers from five labor-intensive enterprises in Foshan City were surveyed from August to September 2019 with the Effort-Reward Imbalance questionnaire. Binary logistic regression was used to analyze the influencing factors of occupational stress.
Results Totally 1 228 valid questionnaires were collected, with a recovery rate of 86.48%. Occupational stress affected 42.02% of workers (516 out of 1 228). Regression analysis revealed that the risk of occupational stress of workers in the aluminum manufacturing group was 2.199 times greater than that of workers in the electronic manufacturing group(P < 0.01); the risk of occupational stress of shiftworkers was 1.745 times greater than that of day-shift workers (P < 0.01); and the risk of occupational stress of workers with working times of 2-4 and/or 5-9 years was 0.645 and 0.468 times greater than that of workers with working times less than 1 year (P < 0.05). The risk of occupational stress for workers with average monthly incomes higher than 5 000 yuan was 6.186 times that of workers with average monthly incomes less than 3 000 yuan (P < 0.01).
Conclusions The level of occupational stress among assembly line workers in labor-intensive enterprises was high. It is suggested that enterprises reasonably arrange employees' duties, improve the performance system, appropriately improve their welfare benefits, and carry out mindfulness decompression therapy for those workers in the aluminum manufacturing industry engaged in shift work or with short working times and high average monthly income so as to alleviate their occupational tension.
