Certain proportion of workers developed psychological symptoms within 1 year after occupational injury. Mental health is associated with overall health status. However, few studies examined the effect of psychological symptoms after occupational injury on long-term health status. This study aims to determine the impact of psychological symptoms within 1 year after occupational injury on health status six years later.Method
2308 workers who sustained an occupational injury in 2009 and responded to a survey at 3 or 12 months after their injury were followed up in 2015. At 6 years after the injury, they were invited to participate in a questionnaire survey, which included return-to-work condition and self-rated health status.Population attributable risks (PARs) were estimated to assess the effect of psychological symptom on self-rated poor health.Results
A total of 570 workers (33.5%) completed the questionnaire. Injured workers who had adverse life event within follow-up period, had family member requiring care, did not return-to-work within 1 year after the injury, had severe psychological symptom within 1 year after the injury, and whose physical appearance was severely affected had a higher risk of self-rated poor health. Adverse life event within follow-up period was most important factor, accounting for 34.3% of self-perceived poor health, followed by severe psychological symptom within 1 year after the injury (15.0%), and severely affected physical appearance (11.7%).Conclusion
Injury severity and severe psychological symptoms after occupational injury were risk factors for poor health status. Interventions addressing these factors are warranted to reduce psychological ailments after occupational injury.
