Study Finds Limited Availability of Child Safety Seat Types For Obese Young Children

COLUMBUS, OH - 4/3/2006

Childhood obesity is a critical health issue. And the use of child safety seats is required by law. But how many child safety seat types are available for the increasing number of obese children? Not nearly enough—according to a study published in the April issue of Pediatrics and conducted by Lara Trifiletti, PhD, MA, of the Center for Injury Research and Policy in the Columbus Children’s Research Institute at Columbus Children’s Hospital and assistant professor in the Department of Pediatrics at The Ohio State University.

According to study estimates, a total of 283,305 children one to six years of age in the United States would have a difficult, if not impossible, time fitting safely and appropriately into a child safety seat because of their age and weight. The vast majority of these children are three years of age and weigh more than 40 lb (182,661 children). For these children, there are currently only four child safety seat types available, each of which costs between $240 and $270.

“While we await reductions in the childhood obesity epidemic, it is essential to develop child safety seats that can protect children of all shapes and sizes,” Trifiletti said. “Motor vehicle crashes pose the single greatest risk to children, accounting for 23% of injury deaths among infants and 30% among preschool-aged children. Options for maximizing the protection of obese children in automobiles must be identified.”

The types of appropriate child safety seats were assessed by using National Highway Traffic Safety Administration 2005 Child Safety Seat Ease of Use Ratings. Estimates of the numbers of children weighing above the maximal weight for those child safety seats were calculated by using the tabulations of growth curves based on National Health and Nutrition Examination Survey 1999 to 2000 data that were assembled by the National Center for Health Statistics and the US Census for the year 2000.

Obesity is generally considered a health problem with long-term consequences. However, there is an immediate need for child safety seats that have been designed, tested and approved for use at higher weights.

“Debate regarding what to do to reduce and to prevent childhood obesity is just beginning,” Trifiletti said. “We do know, however, that childhood obesity is increasing, and we can expect even more children to face the prospect of limited child safety seats available to protect them.”

This research was supported and conducted in collaboration with researchers from by the Johns Hopkins Bloomberg School of Public Health’s, Center for Injury Research and Policy in Baltimore, Maryland and conducted in collaboration with its researchers.
