1 ALCOHOL S BURDEN (with special attention to Africa and the NCDs) Isidore S. Obot, PhD, MPH Professor of Psychology, University of Uyo Director, Centre for Research and Information on Substance Abuse (CRISA), Uyo/Abuja, Nigeria

2 Outline Introduction Why alcohol is associated with harm Alcohol s attributable death and DALYs The economic and social costs The burden of NCDs Confronting NCDs: evidence for action The best buys Conclusion

3

4 DALYs lost attributable to 10 leading risk factors for the age group years in the world, 2004

5 Why the high burden?

6 Evidence shows that: (i) the volume of lifetime alcohol use and (ii) a combination of frequency of drinking and amount drunk per drinking occasion increase the risk of alcohol-related harm, largely in a dose-dependent manner

7 Alcohol is an intoxicant Alcohol is an intoxicant affecting a wide range of structures and processes in the central nervous system Alcohol interacts with personality characteristics and sociocultural expectations Alcohol is a causal factor for intentional and unintentional injuries and harms to people other than the drinker, including interpersonal violence, suicide, homicide, crime and drink-driving fatalities, Alcohol is a casual factor for risky sexual behaviour, sexually transmitted diseases and HIV infection.

8 Alcohol is a dependence producing substance Alcohol is a dependence-producing drug, similar to other substances under international control, through its reinforcing properties and neuro-adaptation in the brain

9 Alcohol is a toxic substance Alcohol has direct and indirect effects on a wide range of organs and systems. Beverage alcohol is classified as a carcinogen by the International Agency for Research on Cancer. Alcohol increases the risk of cancers of the oral cavity and pharynx, oesophagus, stomach, colon, rectum and breast in a linear dose-response relationship.

10 Alcohol is an immunosuppressant Alcohol increases the risk of communicable diseases, including tuberculosis and community acquired pneumonia.

11 Alcohol and young people The adolescent brain is particularly susceptible to alcohol. There is evidence that drinking can impair educational attainment due to effects on cognitive functions.

12 Harms associated with alcohol We can measure the negative impact of alcohol on at least three different areas: 1. Economic costs 2. Harm to the individual 3. Harm to the society

13 The more you drink

14 Harm to the individual: Alcohol and non-communicable diseases Cancer Cardiovascular disease (heart disease and strokes) Diabetes Chronic respiratory diseases

15 NCDs: Behavioural risk factors and their determinants Risk Factors Tobacco Harmful use of alcohol Unhealthy diet (salt and fat) Physical inactivity Social Determinants Socio-economic status Environment (social and physical) Socio-cultural Gender Poverty

16 4 diseases + 4 risk factors NCDs Cardiovascular diseases Tobacco use Risk factors Unhealthy diets Physical inactivity Harmful use of alcohol Diabetes Cancer Chronic lung disease

17 Burden of NCDs 40% of all deaths in Africa are attributable to NCDs and injuries 20% due to premature deaths from preventable conditions 13% due to other deaths 7% due to injuries

30 Evidence for action There is at present clear and growing evidence for the following: Alcohol s harm to the drinker, others, and society Availability of effective interventions

33 No beneficial effects of alcohol in Africa Analysis of death and disease burden in 2009 showed: High detrimental effects of alcohol due mainly to alcohol attributable unintentional and intentional injuries Higher burden among men than women Higher burden in AFR E than in AFR D and No beneficial effects of alcohol Source: Roerecke, Obot, Petra & Rehm (2009)

34 REDUCTION OF THE HARMFUL USE OF ALCOHOL: A STRATEGY FOR AFRICA Priority areas Awareness and community action Public education Health sector response Information, surveillance and research Drink-driving legislation and countermeasures Marketing regulation Access, availability and affordability Illegal and informal production

36 Conclusion NCDs have become a developing world problem. 85% of people who die from NCDs between the ages of 30 and 69 years live in a developing country. The estimated cumulative lost output in developing countries associated with NCDs between is 7 trillion US$. The overall cost of scaling up action by implementing a set of best buys interventions to prevent premature deaths is 170 billion US$. Effective interventions exist for different risk factors. For alcohol, reduction in levels of consumption and prevalence of HED are beneficial to public health.
