Minority children might be at greater risk for car crash-related injuries because fewer wear seat belts, a study finds. The study, presented Saturday at the American Academy of Pediatrics' national conference in Boston, looked at statistics on 37,375 children younger than 16 collected from the National Trauma Database from 2002 to 2006. Among those children, less than half -- 45.7% -- were in restraints. The lowest use of seat belts was found among black, Hispanic and Native American children.
