The alcohol-attributable fraction (AAF) denotes the proportion of a health outcome which is caused by alcohol (i.e. that proportion which would disappear if alcohol consumption was removed). Alcohol consumption has a causal impact on more than 200 health conditions (diseases and injuries).
Method of estimation:
Population-attributable fractions are calculated based on the level of exposure to alcohol and the risk relations between consumption and different disease or injury categories. For each disease the exact proportion is different and will depend on the level and patterns of alcohol consumption, and on the relative risks.
