Introduction: Injuries sustained by adolescents in Canada represent a costly public health issue. Much of the limited research in this area uses administrative data, which underestimate injury prevalence by ignoring injuries that are not treated by the health care system. Self-reported data provide population-based estimates and include contextual information that can be used to identify injury correlates and possible targets for public health interventions aimed at decreased injury burden. Methods: The 2017 wave of the Canadian Community Health Survey was used to calculate the prevalence of self-reported total, intentional and unintentional injuries. We compared injury prevalence according to age, sex, employment status, presence of a mood disorder, presence of an anxiety disorder, smoking and binge drinking. Analyses were performed using logistic regression to identify significantly different injury prevalence estimates across key correlates. Methods: The 2017 wave of the Canadian Community Health Survey was used to calculate the prevalence of self-reported total, intentional and unintentional injuries. We compared injury prevalence according to age, sex, employment status, presence of a mood disorder, presence of an anxiety disorder, smoking and binge drinking. Analyses were performed using logistic regression to identify significantly different injury prevalence estimates across key correlates. Conclusion: The data suggest that injury prevention interventions aimed at reducing alcohol consumption, particularly binge drinking, may be effective in reducing adolescent injury across Canada. Future research is needed to determine how provincial context (such as mental health support for adolescents or programs and policies aimed at reducing substance use) impacts injury rates.

Background: Injuries are among the top 10 leading causes of death in Canada. However, the types and rates of injuries vary between rural versus urban settings. Injury rates increase with rurality, particularly those related to motor vehicle collisions. Factors such as type of work, hazardous environments and longer driving distances contribute to the difference in rural and urban injury rates. Further examination of injuries comparing rural and urban settings with increased granularity in the nature of injuries and severity is needed. Methods: The study population consisted of records from the electronic Canadian Hospitals Injury Reporting and Prevention Program (eCHIRPP) from between 2011 and July 2017. Rural and urban status was determined based on postal codes as defined by Canada Post. Proportionate injury ratios (PIRs) were calculated to compare rural and urban injury rates by nature and severity of injury and sex, among other factors. Results: Rural injuries were more likely to involve multiple injuries (PIR = 1.66 for 3 injuries) and crush injuries (PIR = 1.72). More modestly elevated PIRs for rural settings were found for animal bites (1.14), burns (1.22), eye injuries (1.32), fractures (1.20) and muscle or soft tissue injuries (1.11). Injuries in rural areas were more severe, with a higher likelihood of cases being admitted to hospital (1.97), and they were more likely to be due to a motor vehicle collision (2.12). Conclusion: The nature of injuries in rural settings differ from those in urban settings. This suggests a need to evaluate current injury prevention efforts in rural settings with the aim to close the gap between rural and urban injury rates. [ABSTRACT FROM AUTHOR]

Objective: Cross-sectional epidemiologic studies have inconsistently reported associations between injuries and depressive symptoms. The significance of these findings remains unclear. Major depressive episodes (IVIDEs) may increase the risk of injury and injuries may increase the risk of iVIDEs. Longitudinal data are needed to distinguish between these possibilities. Method: Data from the Canadian National Population Health Survey (NPHS) were used in this analysis. The NPHS is a prospective study based on a representative sample of household residents in Canada. Injuries were evaluated using self-report items. MDE was assessed using the Composite International Diagnostic Interview-Short Form for major depression. Results: During each round of interviews, an association between MDE and injuries was evident. In longitudinal analyses a bidirectional association was found. MDEs increased the risk of injury (adjusted hazard ratio [HR] 1.6, 95% CI 1.3 to 2.0) and injury increased the risk of MDEs (adjusted HR 1.4, 95% CI 1.1 to 1.8). Conclusions: Injury prevention efforts may benefit from consideration of MDE as an injury determinant. For example, particular occupational or recreational activities may have a higher risk of injury during depressive episodes. Improved access to mental health resources in clinical settings where injuries are treated may also be valuable. However, additional studies are necessary to confirm these observations and to develop evidence-based interventions. [ABSTRACT FROM AUTHOR]
