Objectives Our study was conducted to investigate the effects of job demand and control on occupational injuries among Korean EMS workers.
Methods Data from Self-reported questionnaires of Korean EMS workers was used to investigate characteristics of subjects. Data included individual factors (age, sex, marital status, smoking status, alcohol consumption, frequency of exercise, and education) and job-related factor(current job categories, and current job experience). Those who have a score above the median of job stress scale for Korean employees were defined as high job demand group or low job control group. Odds ratio and 95% confidence interval of occupational injuries in subjects with high job demand or low job control was calculated by using negative binomial model.
Results Among EMS workers, the odds ratio of occupational injuries in subjects with high job demand was 1.80 (95% confidence interval 1.50–2.16), and 1.14 with low job control (95% confidence interval 0.94–1.37). The results were calculated after adjusting for sex, age, marital status, smoking status, current job, and current job experience.
Conclusion high job demand was associated with occupational injuries among EMS workers.
