OBJECTIVES: This study evaluated the contributions of rural residence, alcohol use, and pedestrian fatalities to the high American Indian motor-vehicle crash mortality rate in Arizona. METHODS: Records from the Fatal Accident Reporting System were used to examine mortality rates between 1979 and 1988. RESULTS: American Indians had increased relative risks in all motor-vehicle crash categories in all residence-gender groups. The percentage of excess mortality associated with alcohol varied from 36.8% to 66.7%, and the percentage associated with pedestrian deaths ranged from 27.2% to 55.4%. CONCLUSIONS: Efforts to reduce excess motor-vehicle crash mortality among American Indians should concentrate on preventing pedestrian and alcohol-related fatalities.
