Globalization – I
• Rapid economic integration carried out on a global scale • Compression of time and space• Technology facilitated• Values driven – accumulation of wealth,
growth, social connectors• Capitalism unchecked• Integrating and fragmenting
![Page 3: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/3.jpg)
Globalization II• New heights of achievement in wealth,
technology, and food production: Since 1820, 50-fold increase in real world output and 6-fold increase in world population
• New heights in disparities: Trends in global income inequality by (income/cap ratio between world’s richest and poorest countries): 1800—3:1 ; 1900—10:1; and by 2000—60:1

Globalization - III• Not new but more rapid• European conquest of Americans from 15th
century onward• Introduction of tuberculosis, smallpox, yellow
fever, malaria in immunologically naive population led to 50-80 million deaths
• Agriculture products to Europe - corn, potatoes, tomatoes, tobacco, chillies etc.

Globalizations Impact on Health?
• Shapes the determinants of health• Directly affects health status and outcome• Societies must adapt collective responses to
changing health determinants and outcomes
![Page 6: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/6.jpg)
Transitional Factors• Macroeconomic –(structural adjustment etc.)• Trade—liberalization, foreign investment• Travel• Communication• Migration and demographic changes• Behavioral changes• Food production/security and dietary habits• Environmental degradation• Technology development and transfer (IPR)• Break down of public sector programs
![Page 7: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/7.jpg)
Health Risks • Pollution of air and water• Export of tobacco, alcohol, psychoactive drugs • Production of unsafe drugs, counterfeit drugs, spread of
drug resistance• More rapid spread of infectious diseases• Export of life styles—diet, less physical activity • Increase consumption of foods increasing risks—
saturated fats, salt, sugar• Inappropriate health products• Global warming
![Page 8: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/8.jpg)
Other Factors Impacting on Health
• Marketing• Role of public and private sectors• Health care financing and service provision• Pharmaceutical industry—development,
production, and distribution• Health sector reform• Manpower development and migration
![Page 9: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/9.jpg)
Public Health Benefits of Globalization
• Disease eradication (smallpox)• Vaccines & therapeutic agents R & D• Drugs and vaccines that are inexpensive and
more widely available• Diagnostic techniques improved • Communications improved • Access to scientific data and literature• More safe water• Better surveillance

Defining and Improving Global Health
![Page 23: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/23.jpg)
Global Health-Definitions
• Limited definitions are often based on the following: health problems (ID, NCDs); populations of interest (the poor); geography (global South); mission (equity)
• Two key elements to a definition: level of analysis; degrees of interdependence
• Two dimensions should be analyzed: health conditions; how society responds
![Page 24: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/24.jpg)
Global Health-Definitions II
• An area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide (Koplan et al-Lancet)
• The goal of global health is to improve the health of all people in all nations by promoting wellness and eliminating avoidable diseases, disabilities, and deaths. It can be attained by combining clinical care….. with population-based measures to promote health and prevent disease. (IOM—US—2008)
![Page 25: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/25.jpg)
Health as a Public Good - I
• Non-divisibility - none cut out• Non-excludability – all benefit• Broad themes
• Equity – Increased disparity• Markets – Privitization• Opportunity
![Page 26: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/26.jpg)
Health as a Public Good - II
• Forces pushing the agenda• Trade, migration, information• Increased pressure on common pool resources
– esp. air and water• Responsibilities for health is local, but the
determinants of health are increasingly global
![Page 27: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/27.jpg)
Health as a Public Good
• Non-divisibility - none cut out• Non-excludability – all benefit• Increasing disparity in terms of equity, and
privatization of markets• Increased pressure on common pool resources
– esp. air and water• Responsibilities for health is local, but the
determinants of health are increasingly global
![Page 28: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/28.jpg)
Why Improve Health?
• Reduce unnecessary morbidity• Reduce premature mortality• Improve individual and group potential for
development• Create greater equity • Reduce the cost of poor health in terms of trade,
and travel
![Page 29: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/29.jpg)
Globalizing Health and the Health Sector
• Disease—democratization of microbes, NCDs• Risk factors—diet, smoking, air and water pollution
(common public goods)• Health professionals—movement of nurses, doctors,
allied professionals• Drugs—availability, production, standardization,
counterfeit products, trade• Technologies—rapid spread of information, wide
availability of devices
![Page 30: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/30.jpg)
Global Efforts to Improve Health
• Convention on the Rights of the Child• Polio eradication campaign• Global Outbreak Alert and Response Networks
(GOARN--built on Flu Net etc.)• Tobacco treaty• WTO agreement an drug pricing• Global Fund for HIV/AIDS/TB/Malaria• GAVI
![Page 31: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/31.jpg)
Global Health Governance
• WHO – WH Assembly one vote per country• World Bank – Executive Board – Directors
representing members with votes weighted by ownership of Bank’s capital
• Global Fund and GAVI – Board with members including governments, agencies, CSOs, private sector
• National Aid Agencies – politicians, citizens• Private Philanthropy and Corporations – owners
![Page 32: Richard A. Cash, MD, MPH 4 September 2013 Globalization and its Impact on World Health](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649de75503460f94ae071e/html5/thumbnails/32.jpg)
Global Health—Challenges
• Unfinished agenda of infectious diseases, under nutrition, reproductive health issues
• Rising burden of NCD’s and associated risk factors (smoking, diet etc.)
• Globalization and risk factors that are outside the traditional health areas
• Local and global inequities in health and national differences in health and health systems
• Changing definitions of diseases and risk factors
