2 Alcohol consumption and Sustainable Development Goals
Alcohol causes large global health, social and economic burdens
SDG 3.5: “strengthen prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol”
Reductions in alcohol consumption will help in achieving the SDG goal of “a reduction of premature mortality from non-communicable diseases by a third by 2030”
3 4 Alcohol-Attributable Global Burden of Disease
5 Alcohol-attributable burden of disease
2016 burden of disease attributable to alcohol consumption • 3.0 million deaths; 5.3% of all deaths globally • 131.6 million DALYs; 5.1% of all DALYs global
Change in the age-adjusted alcohol-attributable burden of disease: 2000 to 2016 • -18.1% for deaths • -14.6% for DALYs
Change in the age-adjusted burden of disease: 2000 to 2016 • -23.7% for deaths • -25·2% for DALYs
6 Effects of Alcohol on Health
7 Diseases and injuries causally related to alcohol consumption
8 9 52.4% of all AA deaths occurred before 60 years of age
10 Main indicators of alcohol consumption
Data from population surveys / imputation
Amount of alcohol Prevalence of current Prevalence of people who Amount of alcohol consumed during heavy drinkers, former drinkers are heavy episodic drinkers consumed by age and sex drinking occasions and lifetime abstainers
Country level alcohol consumption data
Adult per capita consumption of alcohol
Adult p er ca pita consumption Adult p er ca pita consumption Adult per capita consumption of alcohol by tourists and of recorded alcohol of unrecorded alcohol from cross-border shopping
11 Data sources - overview
Data collection recorded WHO survey to FAO and other Industry Other counterparts UN organizations
Data collection tourist collection Data verification UN statistics WHO process via Country statistics countries
Data collection unrecorded Delphi round of Survey of general Studies Other national experts population Modelling overview Alcohol Questions for Surveys A subset of key questions from alcohol surveys
14 Main findings: APC • Between 1990 and 2017, APC decreased from 8.5 L (95% CI 8.3–8.6) to 7.9 L (7.5–8.3) • APC is projected to remain stable with an estimated APC of 7.8 L (95% CI 6.9–8.9) by 2030 – This is contrary to the objectives of: oGlobal Strategy on Alcohol and Health oWHO’s Global Action Plan for the Prevention and Control of NCDs oThe Sustainable Development Goals

25 Main findings: drinking status The prevalence of lifetime abstention (LA) decreased from 20.2% (95% CI 17.7–22.8) in 1990 to 16.9% (14.6–19.4) in 2017 -A further decrease in the prevalence of LA is expected: 15.3% (95% CI: 12.9-18.2) in 2030.
The prevalence of heavy episodic drinking (HED) increased slightly form 24.3% (95% CI: 22.0-26.6) in 1990 to 25.1% (95% CI 22.6-27.6) in 2017 -A further increase in the prevalence of HED is expected: 26.4% (95% CI 23.7 to 29.1) in 2030.

31 Standard drink of alcohol
32 Why use a standard drink?
The amount of alcohol in a standard drink us useful to define for:
• Economics • UK Weights and Measures Act (1963, 1985, 2001)
• Low-risk drinking guidelines (originally dietary
• Studies measuring alcohol consumption
33 A standard drink in the United States
First appeared in the 1985 US Dietary guidelines
A standard drink is any drink that contains about specified amount of pure alcohol

37 Labelling
38 Drinkers’ knowledge of what a standard drink
Drinkers underestimate the alcohol content of beverages based on %ABV – Australia (Stockwell et al., 1991)
Beer is the most standardized and easiest to report -Sold in single serve containers -Variations in strength and container size -A single poor would lead to over-pouring of stronger brands (Kerr et al., 2012)
For wine and spirits there is a tendency to over pour drinks -Generally poor awareness of wine volume pours (Devos-Comby et al., 2006) -Historically increased serving size and strength for wine (Britton et al., 2016) -Over pouring dependent on size and shape of vessel
39 Measuring Alcohol Use Disorders
Multiple definitions of Alcohol Use Disorders: -DSM–III–R, DSM–IV, DSM 5, and ICD–10 Multiple diagnostic instruments -Composite International Diagnostic Interview (CIDI) -Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS) -Schedules for Clinical Assessment in Neuropsychiatry (SCAN) -Semi–Structured Assessment for the Genetics of Alcoholism (SSAGA) -Hazardous drinking identification: AUDIT, ASSIST, CAGE, MAST, SSAGA 40 Using the AUDIT as an indicator of Alcohol Use Disorders
