The US Consumer Product Safety Commission estimated that an average of 254 allterrain vehicle (ATV)related deaths occurred annually in the 1990s.1,2 Despite widespread education and training efforts by the Consumer Product Safety Commission and major ATV manufacturers,3 average annual deaths have risen to 267 since 1995.1 Renewed efforts are directed at adolescents younger than 17 years, among whom more than one third of ATV-related deaths have occurred.4 The Specialty Vehicle Institute of America's annual list5 of state-specific ATV safety requirements for 2000 can be viewed as 3 mutually exclusive groups: (1) helmet and other safety equipment requirements (21 states), (2) machine-related safety but no helmet requirement (23 states), and (3) no safety legislation (6 states and the District of Columbia). Death data, obtained from the Consumer Product Safety Commission, were divided into 4 age groups: 116 years, 1749 years, 5064 years, and 6584 years. The few deaths in persons older than 84 years were not included. Although the Consumer Product Safety Commission has estimated death rates based on national ATV user information to identify broad populations at risk,6 reliable and accurate state-specific user information is not consistently available from ATV distributors. Therefore, population-based rates were calculated on the basis of US Census Bureau state-, age-, and sex-specific population estimates.7 Rates were based on 10-year composites of numerator and denominator data for 1990 to 1999 and were not calculated for any cell with fewer than 5 deaths.
States without safety legislation had a collective death rate twice that of the other 2 groups0.17 deaths per 100 000 vs 0.08 and 0.09, respectively (see Table 1
Rates based on few events are often subject to large fluctuations. This phenomenon is likely at play with the crude rates presented here. Accepting that limitation and the notion that these rates are not the most valid assessment of risk in terms of ATV user populations, these rates do provide a broad state-by-state population-based risk comparison. To my knowledge, this report is the first comprehensive state listing of sex- and age-specific ATV-related fatality rates. These results also show clearly that states with some level of safety legislation, be it mandated helmet use or machine-related requirements, have substantially fewer deaths and lower fatality rates than do states that have no ATV safety laws.
The research was supported by grant R49/CCR308469 from the Centers for Disease Control and Prevention to the West Virginia University Injury Control Training and Demonstration Center. I am most grateful to Suzanne Marsh for collating census data, assisting in the calculation of rates, and critically reviewing this brief.
