WHAT'S KNOWN ON THIS SUBJECT: Younger age has been identified as an independent risk factor for all-terrain vehicle (ATV)-related injuries. Since the mid-1980s, one-third of ATVrelated deaths have involved children younger than 18 years of age.
WHAT THIS STUDY ADDS:Using national data, we found both similarities and differences between pediatric age groups in the contribution of known risk factors to ATV-related deaths. The observed differences suggest the importance of targeting injury prevention approaches to specific age ranges. . Ninety-five percent of all pediatric fatalities were on adult-size vehicles. Victims ,6 years old had the highest proportion of girls (24%) and passengers (76%), and the lowest helmet use (17%). More than half of 6-to 11-year-old children were vehicle operators; 1 in 4 were carrying passengers in their own age range. Over the study period, 12-to 15-year-old children accounted for more than half of all pediatric ATV-related fatalities. The proportion of youth riding on the road increased with age, as did the proportion of collisions with other vehicles. Older teens had the highest proportions of roadway fatalities (72%) and collision events (63%), and 19% of their crashes involved alcohol. Head injuries occurred in 63% of victims (the major determinant being roadway riding), and helmets reduced the likelihood of head injury among fatal crash victims by 58%.CONCLUSIONS: There were significant differences between pediatric age groups in the relative contribution of known risk factors for ATV-related fatalities. Future injury prevention efforts must recognize these differences and develop interventions based on the age range targeted.
