Child restraint use is higher than ever, according to a report released Sept. 22 by the Children’s Hospital of Philadelphia and the Association for International Automobile Manufacturers. Over an eight-year period, from 1999 to 2007, researchers noted that overall child restraint use increased from 51 percent to 80 percent among children younger than 9. During this same period, age-appropriate restraint use, including booster seats, among 4- to 8-year-olds quadrupled, from 15 percent appropriately restrained in 1999 to 63 percent in 2007.
