Abstract

OBJECTIVES: To assess professional status (PS) differences in the risk of road crash involvement (RCI) (irrespective of crash severity), and to examine the underlying mechanism by evaluating the role of exposure to road risk (ERR). METHOD: A total of 15,271 subjects selected from the French GAZEL cohort were studied. A proportional hazard model for recurrent events was used to calculate the relative risks (RR) of RCI associated with PS. The associations between RCI and PS were investigated by adjusting for ERR (kilometers travelled and risk behaviors on the road). RESULTS: In all, 1890 RCI were reported. Managers have greater crude RCI risk than unskilled workers (male, RR=1.30; female, RR=1.44). This difference was no longer statistically significant when adjusting for factors describing the drivers' behaviors. Female managers' risks were also insignificant when adjusted for vehicle kilometers travelled (VKT). Managers seemed at lower risk of injury when involved in a crash. CONCLUSION: Socially advantaged subjects have the greatest RCI risk. Qualitative and quantitative ERR factors explain these disparities. These results highlight the importance to focus on ERR when studying the effect of an individual characteristic on RCI. They also highlight the importance to analyse separately the"RCI"and the"susceptibility to injury".
