Objective: This study analyses factors associated with work-related traumatic brain injury (TBI), specifically in the construction industry in Ontario, Canada.

Methods: This cross-sectional study utilized data extracted from the Ontario Workplace Safety and Insurance Board (WSIB) records indicating concussion/intracranial injury that resulted in days off work in 2004-2005.

Results: Analyses of 218 TBI cases revealed that falls were the most common cause of injury, followed by being struck by or against an object. Mechanisms of injury and the temporal profile of injury also varied by age. For instance, a significantly higher proportion of injuries occurred in the mornings for young workers compared to older workers.

Conclusions: The results of this study provide important information for prevention of TBI which suggest important age-specific strategies for workers in the construction industry.
