1 Why Non communicable Diseases? Why now? Professor Michelle A. Williams Chair, Department of Epidemiology Harvard School of Public Health November 8, 2012 Addis Ababa, Ethiopia

2 Non communicable Diseases (NCDs) NCDs include CVDs, diabetes, cancer and chronic respiratory disease and mental health Account for 60% of all deaths globally, 80% are in low and middle income countries Contrary to common perception, the burden of NCDs is worst in low & middle income countries In sub Saharan Africa, NCDs are projected to surpass infectious diseases by 2030

3 Non communicable Diseases (NCDs) Prevalence of many of known risk factors for NCDs has dramatically increased in developing countries societal and environmental changes NCDs have serious implications for economic development and growth Affordable solutions exist to prevent 40 to 50% of premature deaths from NCDs 14 million lives per year in developing countries

4 Deaths attributed to 19 leading factors,by country, WHO 2004

5 Percentage of disability adjusted life years (DALYs) attributed to 19 leading risk factors, by country income level, WHO 2004 A DALY is a healthy life year lost

6 Top leading risk factor causes of death in high income coutries, 2004 Risk factor Tobacco use High blood pressure Overweight and obesity Physical inactivity High blood glucose High cholesterol Low fruit and vegetable intake Urban outdoor air pollution Alcohol use Occuopational risks Percentage of total

7 Projected deaths by cause and income (2004 to 2030) WHO Estimates Intentional injuries Other unintentional Road traffic accidents Deaths (millions) Other NCD Cancers CVD High income Middle income Low income Mat//peri/nutritional Other infectious HIV, TB, malaria

13 WHO: Commission on Macroeconomics and Health Ill health undermines economic development and efforts to reduce poverty. Investments in people s health are vital pre conditions for economic growth and human development.

15 The UN Millennium Development Goals and Non Communicable Diseases (NCDs)

16 The UN Millennium Development Goals and Non Communicable Diseases (NCDs) MDGs state that health is critical to the economic, political and social development of all countries NCDs are a major cause of poverty, a barrier to economic development, and a neglected global emergency

17 What is happening in Ethiopia?

18 Population Pyramid, 2011, Ethiopia ~80 86 million Data from EDHS 2011

19 Projections ETHIOPIA source: populationpyramid.net

20 Proportional Mortality NCDs are estimated to account for 34% of all deaths WHO NCD Country Profiles, 2011

21 Urbanization Urban population~ 18% of total population (2010) Rate of urbanization: 4.3% per annum Capital Addis Ababa 2010: ~ 3.6 million 2015: Projected 5.1 million > 97.7% urban and the rest in peri urban fringes Regional cities are also growing fast CIA World Factbook and UNEP

22 A It is not all bad news there are prevention and control strategies that can work

23 Specific Prevention & Control Strategies 1. Raise the priority to NCDs in development work at global and national levels, and integrate prevention & control of NCDs into policies across all government departments 2. Establish and strengthen national policies and plans for the prevention and control of NCDS 3. To promote interventions to reduce the main shared modifiable risk factors for NCDs WHO Global Strategy, Action Plan

24 Specific Prevention & Control Strategies 4. Promote research for the prevention and control of NCDs 5. Monitor NCDs and their determinants and evaluate progress at the national, regional and global levels 6. Promote partnerships for the prevention and control of NCDs WHO Global Strategy, Action Plan

25 WHO Best Buy Interventions Risk factor/ disease Tobacco use Harmful alcohol use Unhealthy diet and physical inactivity Cardiovascular disease (CVD) and diabetes Interventions Tax increases Smoke free indoor workplaces and public places Health information and warnings Bans on tobacco advertising, promotion & sponsorship Tax increases Restricted access to retailed alcohol Bans on alcohol advertising Reduced salt intake in food Replacement of trans fat with polyunsaturated fat Public awareness through mass media on diet and PA Counseling and multi drug therapy for people with a high risk of developing heart attacks and strokes (including those with established CVD) Treatment of heart attacks with aspirin
