Insights
Child passengers in alcohol-related crashes face double the injury risk and higher rates of improper restraint. These findings highlight the critical need for policies to protect children in impaired driving incidents.
Area of Science:
- Pediatric injury prevention
- Traffic safety research
- Public health policy
Background:
- Alcohol involvement in fatal crashes with children is known.
- Non-fatal injury burden on child passengers from alcohol-related crashes is understudied.
Purpose of the Study:
- To assess injury burden in child passengers (ages 1-15) in alcohol-related motor vehicle crashes.
- To examine restraint use among these child passengers.
Main Methods:
- Retrospective cohort study of Wisconsin crashes in 2007.
- Included crashes with injuries or property damage >$1000 involving child passengers (ages 1-15).
Main Results:
- 2.5% of 22,464 child passengers were in alcohol-related crashes.
- Children in alcohol-related crashes had double the injury risk (RR=2.42).
- Inappropriate restraint use was higher in alcohol-related vehicles (34.5% vs 17.1%).
Conclusions:
- Alcohol-related driving significantly increases child passenger injuries.
- Inappropriate child restraint use is linked to alcohol-related crashes.
- Evidence-based policies are recommended to mitigate this public health issue.
Background:
The role of alcohol in fatal motor vehicle crashes involving children has been well established. However, the nonfatal injury burden of alcohol on child passengers has not been comprehensively assessed.
Purpose:
This study sought to determine injury burden and restraint use in child passengers aged 1-15 years in alcohol-related motor vehicle crashes.
Methods:
A retrospective cohort study including all people involved in all crashes with an injury or at least $1000 property damage occurring in Wisconsin in 2007 and involving at least one child passenger aged 1-15 years.
Results:
A total of 22,464 child passengers were involved in motor vehicle crashes in Wisconsin in 2007; 2.5% (n=570) were in alcohol-related crashes. Child passengers in alcohol-related crashes experienced twice the risk of injury compared to non-alcohol-related crashes (risk ratio [RR]=2.42, 95% CI=2.08, 2.80). Two-vehicle crashes that were alcohol-related were more than two times more likely to result in child injury than those that were not (RR=2.78, 95% CI=2.30, 3.35). In alcohol-related crashes, the risk of injury in children was higher if they were passengers in the alcohol-related vehicle compared to the non-alcohol-related vehicle (RR=1.35, 95% CI=1.01, 1.79). Inappropriate restraint of child passengers was higher in alcohol-related vehicles (34.5% vs 17.1%, p<0.00005), particularly in the group aged 4-7 years (70.8% vs 44.9% inappropriately restrained).
Conclusions:
Motor vehicle crashes resulting from alcohol-related driving significantly increased child passenger injury and were associated with inappropriate child passenger restraint. Several evidence-based policies are recommended to address this public health problem.
