We studied 1164 injured Hispanic and 2560 injured non-Hispanic White children newborn through 14 years triaged to the San Diego County Regionalized Trauma System from 1985 through 1990. Incidence rates did not differ by ethnic group. Hispanic children were more likely to be struck as pedestrians (odds ratio [OR] = 1.5) and less likely to be injured in falls (OR = 0.7) than non-Hispanic White children. For motor vehicle and pedal cycle injuries, Hispanic children were more likely not to have been restrained by seatbelts (OR = 4.0) or car seats (OR = 3.7).
