Little is known about the association between psychosocial factors and injury absence in the workplace.
This study aims to assess the association of comprehensive workplace psychosocial factors with work-related injury absence among Korean workers.
The data (n = 7,856) were derived from the First Korean Working Conditions Survey conducted in 2006 with a representative sample (n = 10,043) of the Korean working population. The survey instrument contained questions about hours of work, physical risk factors, work organization, and the effect of work on health/injury. Work-related injury absence was indicated by a dichotomous variable with at least 1 day absence during the preceding 12 months. Logistic regression models were used to calculate odds ratio and confidence interval (CI). Incremental adjustments for sociodemographic, health behavior, and occupational confounding variables were employed in the models.
The overall 1-year prevalence of work-related injury absence in this study was 1.37 % (95 % CI, 1.11–1.63 %). Those who experienced violence at work (adjusted odds ratio (aOR), 7.05 (95 % CI, 2.69-18.5)), threat of violence at work (aOR, 4.25 (95 % CI, 1.32–13.64)), low job autonomy (aOR, 1.79 (95 % CI, 1.17–2.74)), and high job strain (aOR, 2.38 (95 % CI, 1.29–4.42) had an increased risk of injury absence, compared with their respective counterparts (p < 0.05). Among all job types, skilled workers in Korea were at a near fourfold risk of work absence due to occupational injuries, compared with managers in low-risk jobs.
Workplace violence and increased job strain were two key workplace psychosocial factors associated with work-related injury absence.
