Effectiveness of Belt Positioning Booster Seats: An Updated Assessment

This article reports on a study undertaken to provide an updated estimate of the effectiveness of belt-positioning booster (BPB) seats compared with seat belts alone in reducing the risk for injury for children aged 4 to 8 years. The data were collected from a longitudinal study of children who were involved in crashes in 16 states and the District of Columbia from December 1, 1998, to November 30, 2007; data was obtained via insurance claims records and a validated telephone survey. The study sample included children who were aged 4 to 8 years (n = 7,151), seated in the rear rows of the vehicle, and restrained by either a seat belt or a BPB seat. The adjusted relative risk for injury to children in BPB seats compared with those in seat belts was 0.55; thus, children who used BPB seats were 45% less likely to sustain injuries that similarly aged children who used the vehicle seat belt, when considering all crash directions and vehicle model years. This study reconfirms previous reports that BPB seats reduce the risk for injury in children aged 4 through 8 years. Children in side impacts derived the largest relative protection from booster seats. In addition, the results suggest that the effectiveness of backless or high-back booster seats is equal. Backless booster seats are less costly and often more acceptable to older children because of the absence of a back that makes them look like a toddler child restraint. The authors conclude by reiterating the importance of both pediatricians and health educators continuing to recommend as best practice the use of BPB seats once a child outgrows a harness-based child restraint and until he or she is at least 8 years of age.
