    Child and adolescent bicycling injuries involving motor vehicle collisions
    (2019-03-04) Pitt, Tona M; Nettel-Aguirre, Alberto; McCormack, Gavin R; Howard, Andrew W; Piatkowski, Camilla; Rowe, Brian H; Hagel, Brent E
    Abstract Background Bicycle-related injuries are among the most common recreational injuries for children in Canada; moreover, bicycle-motor vehicle collisions often result in serious injuries. This study seeks to examine environmental, motorist, and bicyclist characteristics of bicycle-motor vehicle collisions that resulted in police reported severe injuries in youth (< 18 years old) bicyclists, in Alberta, Canada. Findings Using Calgary and Edmonton police collision reports, 423 youth bicycle-motor vehicle collisions were identified from 2010 to 2014. Forty-three (10.2%) of these collisions resulted in major/fatal (severe) injuries. These severe injury cases were compared with the 380 youth bicycle-motor vehicle collisions resulting in minor or no injury (controls) using classification tree and logistic regression analyses. There were no driver or bicyclist characteristics with a significant effect on the odds of severe injury to youth bicyclists; however, lower odds were found on each of: divided roads with no barrier (aOR = 0.36; 95% CI: 0.13–0.97) or during peak traffic time (aOR = 0.44; 95% CI: 0.16–0.99). Conclusion Personal and environment characteristics should be considered in future research and interventions focused on reducing severe youth bicycle-motor vehicle collision injuries.

    Injury and concussion in youth female rugby: Evaluating and informing injury and concussion prevention strategies
    (2024-06-17) Shill, Isla Jordan; Emery, Carolyn A; Hagel, Brent E; Palmer, Debbie; Pike, Ian; Stokes, Keith A
    Injury and concussion rates in Canadian female high school rugby are the highest reported in youth rugby. The tackle accounts for the largest proportion of injuries. All injury prevention strategy evaluations are in male populations with none in youth females. This is insufficient to improve female player welfare. Therefore, the objectives of this dissertation were to (1) summarise the rugby injury epidemiology literature within youth female rugby, (2) discuss strengths and limitations of the literature using video analysis for rugby injury epidemiology, (3) evaluate the association between tackle-related characteristics and concussion in female rugby (high school, varsity), and (4) evaluate the effectiveness of a rugby-specific neuromuscular training (NMT) warm-up on injury and concussion in high school female rugby. The association between tackle-related characteristics and suspected concussion was examined using a case-control video analysis study. Within female varsity rugby, ball-carrier concussion was associated with head contact intensity of 2/4 and 3-4/4, illegal and tap tackle, and down head position. Tackler concussion was associated with 3 tacklers in the event, tap tackle, head contact intensity of 3-4/4, and away head position. Within a female high school population, ball-carrier concussion was associated with illegal and trip/collision tackle, increased tackle height compared with knee to upper leg, deceleration and no change of speed, and any head contact. Tackler concussion was associated with 2-3 tacklers in the event, tap or trip/collision tackle, sternum to armpit tackle height, down head position, and any head contact. The effectiveness of a rugby-specific NMT warm-up in high school female rugby players was evaluated using a multi-year quasi-experimental study. There was no difference in injury and concussion rates between control and intervention cohorts, as well as no differences based on adherence to the NMT warm-up. All match and training injury burden were estimated to be lower in those that used a NMT warm-up compared with those that did not. These studies provide a summary of injury prevention evaluations in female rugby. To inform appropriate recommendations for female player safety, a multifaceted approach to injury prevention should be considered. A combination of a NMT warm-up and a tackle injury prevention intervention, such as a tackle training program or tackle law change (e.g., lower legal tackle height), should be considered.

    The built environment and active transportation safety in children and youth: a study protocol
    (2019-06-11) Hagel, Brent E; Macpherson, Alison; Howard, Andrew; Fuselli, Pamela; Cloutier, Marie-Soleil; Winters, Meghan; Richmond, Sarah A; Rothman, Linda; Belton, Kathy; Buliung, Ron; Emery, Carolyn A; Faulkner, Guy; Kennedy, Jacqueline; Ma, Tracey; Macarthur, Colin; McCormack, Gavin R.; Morrow, Greg; Nettel-Aguirre, Alberto; Owens, Liz; Pike, Ian; Russell, Kelly; Torres, Juan; Voaklander, Donald; Embree, Tania; Hubka, Tate
    Abstract Background Active transportation, such as walking and biking, is a healthy way for children to explore their environment and develop independence. However, children can be injured while walking and biking. Many cities make changes to the built environment (e.g., traffic calming features, separated bike lanes) to keep people safe. There is some research on how effective these changes are in preventing adult pedestrians and bicyclists from getting hurt, but very little research has been done to show how safe various environments are for children and youth. Our research program will study how features of the built environment affect whether children travel (e.g., to school) using active modes, and whether certain features increase or decrease their likelihood of injury. Methods First, we will use a cross-sectional study design to estimate associations between objectively measured built environment and objectively measured active transportation to school among child elementary students. We will examine the associations between objectively measured built environment and child and youth pedestrian-motor vehicle collisions (MVCs) and bicyclist-MVCs. We will also use these data to determine the space-time distribution of pedestrian-MVCs and bicyclist-MVCs. Second, we will use a case-crossover design to compare the built environment characteristics of the site where child and youth bicyclists sustain emergency department reported injuries and two randomly selected sites (control sites) along the bicyclist’s route before the injury occurred. Third, to identify implementation strategies for built environment change at the municipal level to encourage active transportation we will conduct: 1) an environmental scan, 2) key informant interviews, 3) focus groups, and 4) a national survey to identify facilitators and barriers for implementing built environment change in municipalities. Finally, we will develop a built environment implementation toolkit to promote active transportation and prevent child pedestrian and bicyclist injuries. Discussion This program of research will identify the built environment associated with active transportation safety and form an evidence base from which municipalities can draw information to support change. Our team’s national scope will be invaluable in providing information regarding the variability in built environment characteristics and is vital to producing evidence-based recommendations that will increase safe active transportation.
