Evaluating Risk Factors for Major Head Injuries in Nova Scotia: A Population-Based Study
MetadataShow full item record
Background: Examining factors unique to major head injury (HI) etiogenesis can help reduce the burden of injury by identifying factors amenable to prevention. Objectives: To describe the epidemiology of HI in Nova Scotia. Risk and protective factors unique to HI were also examined specific to falls and Motor Vehicle Collision (MVC) injuries. Methods: Descriptive analyses and regression models were used to examine the socio-demographic profile of HI and associated risk factors using data from the Nova Scotia Trauma Registry. Results: Regression analyses for MVC-related injury found age, injury place, vehicle type and lack of safety restraint to be independently associated with an increased risk of HI. For falls-related injuries, age, time of trauma, injury mechanism and place were significant factors for a HI event. Conclusion: While HI share many similar characteristics to other major injuries, prevention programs must be aware of both common and unique risk factors for head injuries.
