Objective To assess the occupational stress of workers in small manufacturing enterprises after modified assembly line worktable-centered working conditions.
Methods An ergonomic intervention adopting improved worktable-centered conditions was conducted to 261 workers from five small manufacturing enterprises.Comparison of occupational stress was made with 271 workers without intervention approach as the control group to evaluate the intervention effect.
Results Compared to the control group at the end of the intervention,the scores of the intervention group decreased in occupational role,role boundary,physical environment,personal strain,psychological stress,and physical strain (P < 0.05).
Conclusion Ergonomic measures such as improving worktables and working conditions could effectively decrease the occupational stress of workers.Future studies should focus on expanding ergonomics intervention measures to reduce occupational stressgroup
