Insights
Child pedestrian-car collisions are a major cause of injury. Higher impact speed and vehicle damage correlate with more severe injuries and lasting physical and psychological sequels in children.
Area of Science:
- Pediatric trauma
- Road safety
- Injury epidemiology
Background:
- Pedestrian-car collisions are a leading cause of unintentional injury-related death and morbidity in children in motorized countries.
- Understanding the factors influencing injury severity and outcomes is crucial for prevention strategies.
Purpose of the Study:
- To assess correlations between the mode of pedestrian-motor-vehicle collisions and the severity or post-traumatic sequels in children.
- To identify key factors contributing to injury severity and long-term effects.
Main Methods:
- A 12-year retrospective study (1989-2001) of children aged 0-16 years injured in pedestrian-motor-vehicle collisions.
- Anonymous surveys with questionnaires completed by families of 217 injured children.
Main Results:
- Lack of visibility was the leading cause of injury (vehicle 45%, pedestrian 39%).
- Children injured in groups with other children had higher injury severity scores (P=0.016).
- Injury severity correlated positively with impact speed (r=0.31) and distance thrown (r=0.29).
- Physical sequels were reported by 27% and psychological disturbances by 23% of families.
- Impact speed correlated with physical sequels (P<0.001), and vehicle deformation with behavioral disturbances (P<0.004).
Conclusions:
- Post-traumatic sequels are associated with higher impact speed, lack of braking, and greater vehicle deformation.
- Visibility issues and the circumstances of the collision (e.g., being with other children) are significant factors.
- These findings highlight the need for improved road safety measures for child pedestrians.

Pedestrian-car collisions are in motorised countries one of the leading causes of unintentional-injury-related death and morbidity among children. The objective of this study was to assess correlations between the mode and the severity or post-traumatic sequels of the injury. A 12-year (1989-2001) retrospective study of children aged 0-16 years injured in pedestrian-motor-vehicle collisions was undertaken. An anonymous survey with questionnaires completed by families was conducted. In this time period, 501 children (average age: 7.9 years) were injured. The lack of visibility of the vehicle (45%) and/or the pedestrian (39%) was the leading cause of injury. The mean injury severity score was 6.0 (1-75) and the mortality rate was 0.8% ( n=4, injury severity scores 47, 75, 75, 75). In this study, 217 questionnaires were analysed. When the children were injured, 37% of them were alone, 32.3% were in the presence of accompanying adults, and 24.0% were in the presence of other children. The latter group suffered the highest injury severity score ( P=0.016). Positive correlations were noted between injury severity score and impact speed ( r=0.31, P<0.001) and the distances that the children were thrown off or transported on the vehicle front ( r=0.29, P<0.001). Physical sequels were reported by 27% of the families, and 23% noted psychological disturbances. A positive correlation was noted between impact speed and the occurrence of physical sequels ( P<0.001). The number of deformed parts per vehicle was correlated to the occurrence of behavioural disturbances ( P<0.004).
Conclusion:
The incidence of post-traumatic sequels seems to be associated with higher speed at impact, lack of braking attempts, and higher numbers of vehicle parts deformed.
