Alcohol's percentage of the global health burden is large and still growing, researchers say.
"Alcohol consumption has been found to cause more than 200 different diseases and injuries," said Kevin Shield, the lead author of the study. "These include not only well-known outcomes of drinking such as liver cirrhosis or traffic accidents, but also several types of cancer, such as female breast cancer."
Preventable Disease and Injury
Of the 67 health risk factors studied, alcohol was responsible for 5.5% of all worldwide disease and injury health burdens, the study revealed.
"Improving alcohol control policies presents one of the greatest opportunities to prevent much of the health burden caused by alcohol consumption," Shield said in a news release "To improve these policies, information on how much alcohol people are consuming, and how people are consuming alcohol is necessary, and that is exactly the information this article presents."
The study, published in the journal Addiction, was conducted at the Centre for Addiction and Mental Health (CAMH) in Canada and reported the patterns of alcohol consumption by country. The results showed large differences between drinking by geographical regions.
World's Heaviest Drinkers
According to the study:
- The world's heaviest drinkers are in Europe and parts of sub-Saharan Africa.
- Drinkers in Eastern Europe and southern Africa consume large quantities, drink to the get drunk, and go on prolonged binges.
- The least amount of alcohol is consumed in North Africa, the Middle East, and South Asia.
- North Americans consume 50% more alcohol than the worldwide average.
