REGIONAL DIFFERENCES IN ALCOHOL AND FATAL INJURY - A COMPARISON OF DATA FROM 2 COUNTY CORONERS

Objective: While alcohol has been found to be associated with fatal in jury, this association may vary in different regions of the United Sta tes where drinking patterns and problems are known to vary. The purpos e of this study was to analyze alcohol in injury fatalities in a ''dry '' area of the country (Hinds County, Miss.) compared to a ''wet'' are a (Contra Costa County, Calif.). Method: Data on all unnatural causes of death during a 1-year period among those 18 years and older were ab stracted from county coroner records in Hinds County, Miss. (n = 222) and Contra Costa County, Calif. (n = 304). Results: Across all causes of death, those in Hinds County were more likely to be alcohol-involve d (57%) compared to those in Contra Costa (40%). Those in Hinds County were twice as likely as those in Contra Costa to have died from homic ide (32% vs 17%), but the proportion of homicides which was alcohol po sitive did not differ between the two regions (51% vs 46%). Using logi stic regression, gender (male) and region (South) were predictive of a positive blood alcohol concentration across all causes of fatality co mbined. Age (younger) and ethnicity (black) were predictive of homicid e. Ethnicity (non-black), a negative blood alcohol concentration and a positive drug screen were predictive of suicide, while age (younger), ethnicity (non-black), a positive blood alcohol concentration and a n egative drug screen were predictive of motor vehicle accidents. Conclu sions: These data suggest that regional variations in alcohol's associ ation with fatal injury do exist, and vary by demographic characterist ics and cause of death. In addition, areas of the country that have re latively low rates of per capita consumption may have higher rates of alcohol-related injury fatalities than areas with greater per capita c onsumption.
