Abstract

Although alcohol has been found to be more closely associated with violence-related injury than with injury from other causes, few data are available that document heterogeneity in this association across countries or cultures, taking into consideration usual drinking patterns and other sociocultural variables. Data are reported from 15 countries comprising the Emergency Room Collaborative Alcohol Analysis Project and the WHO Collaborative Study on Alcohol and Injury. Case-crossover analysis was used to analyze the risk of injury (among current drinkers) from drinking 6 hours prior to the event, based on frequency of usual drinking, for violence-related injuries and separately for non-violence-related injuries. Relative risk (RR) for a violence-related injury was significantly greater than for injuries from other causes across all countries (pooled RR = 22.22 vs. 4.33), but the magnitude of risk varied considerably (ranging from 4.68 in Spain to 942 in Canada). Pooled effect size was found to be heterogeneous across countries, and was explained, in part, by the level of detrimental drinking pattern in a country. Risk for a violence-related injury was not significantly different by age (<30 and 30+ years), reporting five or more drinks on at least one occasion during the last year, or reporting symptoms of alcohol dependence. A number of methodological concerns suggest that risk of a violence-related injury compared with injuries from other causes may be inflated, and such variables as context of drinking should be taken into consideration in establishing relative risk and alcohol attributable fraction of violence-related injury across countries and cultures.
