Estimates of alcohol-related burden in South America
• Epidemiological developments (i.e. changes in distribution of disease such as chronic disease vs. infectious disease)
• Changes in drinking (average level and patterns of drinking) => slides with green background
Exposure: Characteristics of adult alcohol consumption in different
regions of WHO AMRO:
based on CRA 2000 (i.e. no new data on consumption included)
(population weighted averages across countries; cf. Rehm et al., 2003b, 2004; Babor et al., 2003)

Comparison of alcohol-related deaths of 2002 to 2000 –
epidemiological model only • For all of America, the relative size of
mortality of alcohol-related deaths decreased slightly (4.4% in 2002; 4.7% in 2000).
• The numbers of alcohol-related deaths -decreased in all three regions, with biggest decreases in America Region D.
• For the world, the relative size of alcohol-related deaths stayed at about the same level (3.2% in 2000; 3.1% in 2002).

Comparison of alcohol-related deaths from 2000 to 2002 – best
estimates for 2002• There are no major changes in estimates of
alcohol-related mortality from 2000 to 2002• Two developments:
– Epidemiological change -> less deaths in alcohol-related categories
– More heavy drinking -> more deaths….
• Americas continue to have a high mortality burden from alcohol
• Please note, that this is a net burden, after subtracting cardio-protective effects

Comparison of alcohol-related DALYs from 2000 to 2002 – best
estimates for 2002
• There are no major changes in estimates of alcohol-related burden of disease from 2000 to 2002
• Americas continue to have a burden of disease from alcohol
• Please note, that this is a net burden, after subtracting cardio-protective effects
Relative impact of alcohol for different age groups
• For all three regions, for both genders, with one small exception, the relative weight of alcohol on deaths is strongest in the age group 15-29 years of age
• In this age group, there are no beneficial effects of alcohol on mortality

Conclusion for policy -> main targets based on epidemiology
This is the major aim of this conference, but from an epidemiological side, policies to reduce health burden in the following areas should be considered:
• Heavy drinking occasions • Overall level of consumption• Youth• Injury• Alcohol use disorders
