Abstract
BackgroundA previous review showed that high stress increases the risk of occupational injury by three- to five-fold. However, most of the prior studies have relied on short follow-ups. In this prospective cohort study we examined the effect of stress on recorded hospitalised injuries in an 8-year follow-up.MethodsA total of 16,385 employees of a Finnish forest company responded to the questionnaire. Perceived stress was measured with a validated single-item measure, and analysed in relation recorded hospitalised injuries from 1986 to 2008. We used Cox proportional hazard regression models to examine the prospective associations between work stress, injuries and confounding factors.ResultsHighly stressed participants were approximately 40% more likely to be hospitalised due to injury over the follow-up period than participants with low stress. This association remained significant after adjustment for age, gender, marital status, occupational status, educational level, and physical work environment.ConclusionsHigh stress is associated with an increased risk of severe injury.
Highlights
A previous review showed that high stress increases the risk of occupational injury by three- to five-fold
A review of 20 studies showed that high stress was associated with a three- to five-fold risk of occupational injury [3]
Gender, and marital status adjusted model, high stress was associated with an increased risk of injury (HR 1.30, 95% confidence intervals (95% CI) 1.08-1.55)
Summary
A previous review showed that high stress increases the risk of occupational injury by three- to five-fold. Most of the prior studies have relied on short follow-ups In this prospective cohort study we examined the effect of stress on recorded hospitalised injuries in an 8-year follow-up. Results: Highly stressed participants were approximately 40% more likely to be hospitalised due to injury over the follow-up period than participants with low stress. This association remained significant after adjustment for age, gender, marital status, occupational status, educational level, and physical work environment. A review of 20 studies showed that high stress was associated with a three- to five-fold risk of occupational injury [3]. Verified, diagnosed injuries would offer a more reliable endpoint
