Alcohol-related measures as factors in traffic fatalities.
OBJECTIVE
The purpose of this study was to determine if alcohol-related measures (per capita consumption, drinking-driving arrest rate, alcohol abuse treatment rate and Alcoholics Anonymous [AA] membership rate) were related to differences between states in traffic fatality rates (total and alcohol-related).


METHODS
Fatality rates were regressed onto the alcohol-related variables, using state level data for 1982 and 1990 as well as measures of relative change between the 2 years.


RESULTS
Fatality rates demonstrated significant positive relationships with per capita consumption and drinking-driving arrest rates, and significant negative relationships with AA membership rates, for the years 1982 and 1990. Also, changes in per capita consumption were significantly and positively related to changes in both traffic fatality measures.


CONCLUSIONS
Per capita alcohol consumption measures were the strongest and most consistent determinants of traffic fatality measures. The negative relationship between AA membership rates and traffic fatality measures for 1982 and 1990 suggests a beneficial impact of AA on these measures at the aggregate level, although other explanations are possible.
