Insights
This study found no significant link between childhood obesity and the severity or type of injuries sustained in car crashes. Overweight children were not more likely to experience severe injuries or misuse restraints.
Area of Science:
- Pediatric Traumatology
- Public Health
- Epidemiology
Background:
- Childhood obesity is a significant public health issue in the U.S.
- The impact of obesity on pediatric traumatic injuries is not well understood.
- Existing research lacks comprehensive data on overweight children involved in motor vehicle collisions.
Purpose of the Study:
- To investigate the relationship between overweight status and injury severity in children involved in motor vehicle collisions.
- To determine if overweight children experience different injury distributions.
- To assess the association between overweight status and the appropriateness of restraint use.
Main Methods:
- Secondary analysis of the Child Injury Prevention and Control (CIREN) database.
- Inclusion criteria: subjects aged 2-17 years involved in motor vehicle collisions.
- Overweight defined as Body Mass Index (BMI) percentile >85% for age; significant injury defined by Injury Severity Score (ISS) >15 or Abbreviated Injury Scale (AIS) >1.
Main Results:
- 35.5% of the 335 subjects were overweight.
- No significant association found between overweight status and overall significant injury (Odds Ratio [OR] 1.2, 95% Confidence Interval [CI] 0.8-1.9).
- No significant associations observed for injury distribution (AIS) or restraint use (OR 1.3, 95% CI 0.8-2.1).
Conclusions:
- The study found no statistically significant relationship between being overweight and pediatric injury severity, injury distribution, or restraint use in motor vehicle collisions.
- Limitations include a small sample size and a high proportion of unrestrained subjects.
- Further research with larger datasets is warranted to confirm these findings.
Background:
Obesity is an epidemic in the United States. The relationship between traumatic injury and obesity in children is not well-studied. We hypothesized that overweight children suffer more severe injuries, different distributions of injuries and improper use of restraints in motor vehicle collisions.
Methods:
We conducted a secondary analysis of the CIREN database of motor vehicle collisions of subjects 2-17 years old. Overweight was defined as a BMI percentile for age >85%. Significant injury was an Injury Severity Score (ISS) >15 or an Abbreviated Injury Scale (AIS) score greater than one. Further analysis looked at injuries classified as head, trunk, or extremities and appropriateness of restraints. Odds ratios compared the overweight to lean groups.
Results:
335 subjects met inclusion criteria with 35.5% of cases being overweight. For significant injury, overweight cases had an odds ratio of 1.2 [95% CI: 0.8-1.9]. Analysis by AIS for overall significant injury and to specific body regions also did not show any significant associations. Overweight versus lean subjects had an odds ratio of 1.3 [95% CI: 0.8-2.1] for improper use of restraints.
Conclusions:
We found no significant relationship between pediatric injury severity, distribution of injuries, or restraint use and being overweight. Limitations of this study were the small sample size in this database and the large number of unrestrained subjects.
