The second issue is how best to estimate AAFs for injury categories? One way would be to apply the same procedure as with chronic disease categories, based on average volume of consumption with risk relations taken from the meta-analyses of Corrao and colleagues [222]. However, this procedure cannot take into consideration the cultural differences between societies in the relationship between alcohol consumption and injury, involving both the physical and social context of drinking and the proportion of heavy drinking occasions in the overall volume of drinking. Particularly for intentional injuries, cultural differences in the meaning of drinking are also involved [223]. For example, Rossow [224] found a considerably greater increase in homicide per litre of alcohol per capita consumption in Nordic countries compared to countries in Southern Europe.
