1 Possible themes for South African- Norwegian Health research collaboration Halvor Sommerfelt, MD, PhD University of Bergen, Currently: University of the Western Cape & Medical Research Council, Cape Town Prof. Mhlanga: A nation without (healthy) women and children is a nation doomed

2 Main messages Cost-effective (mother & child) health promotion programs: Powerful instruments  economic growth and poverty reduction, if:  main disease burden contributors (diseases & risk factors)  research to generate evidence-base for program-relevant interventions  extensive coverage and equitable delivery (Research  functional health system). Experiences from other collaborations, e.g. Indo- Norwegian: RSA as node for health research and post- graduate education in SSA? Suggested areas for collaborative research & post- graduate education in health Suggested strategies for collaborative health research

7 Measles incidence US Vaccine

9 Age-adjusted measles mortality per 1000 US if vaccine available from 1915 Vaccine

10 Historically in industrialized countries: Close link between general std. of living and health, limited effect of specific health interventions 20 th /21 st century transitions (i.e. in developing countries) are often propagated or even initiated by health interventions Declines in mortality and then fertility are often sharper than seen in present day industrialized countries (immunizations, health education, early treatment.....)

11 Historical data on health and disease Countries where large differences in S-E status (e.g. India and South Africa): Different strata of the population are actually simultaneously at two different stages of the demographic and epidemiological transitions! Fight at two fronts: Cheap - to - prevent/treat communicable diseases (of children) vs. expensive - to - treat degenerative diseases of adults/elderly.

12 The good… UN/UNICEF data show that the global child mortality rate has declined from 196 (deaths per 1000 live births) in 1960 to 93 in 1990 to 82 in 2002 Between 1960 and 2002, the child mortality rate has fallen in every country in the world. Immunization coverage increased from 5-10% in 1974 to about 75% by Source: David Bloom and David Canning, Harvard University

13 The bad… 10.5 million children under the age of 5 (=U5) died in 2002, accounting for nearly 20% of all global deaths (U5 only 10% of world population). 6-7 million of those deaths could have been easily averted through immunization and early treatment (as they are due to malnutrition, acute respiratory infections, diarrhea, malaria, and measles). One fourth of children worldwide have not been immunized with DTP. Source: David Bloom and David Canning, Harvard University

14 The ugly…. 98% of child deaths occur in developing countries The ratio of child mortality in developing countries to child mortality in industrial countries was – 5.5 in 1960 –10.3 in 1990 –13.0 in 2002 The child mortality rate increased in 15 countries from , many of which in SSA Source: David Bloom and David Canning, Harvard University

25 Health to income Income A 10 year gain in life expectancy translates into nearly 1 additional percentage point of annual growth of income per capita. Health In addition to this health effect, demographic transition accounted for roughly one-third of the “East Asian miracle”: 2 percentage pts/year. Comparison: E-economy: 2-3 percentage points/year.

26 The bottom line…. The rate of return to investment in the GAVI immunization program is conservatively estimated at 12% in 2005, rising to 18% in Source: David Bloom and David Canning, Harvard University

27 By comparison…. These figures are comparable to average rates of return to investments in schooling (based on a survey of 98 country studies during ): primary: 19% secondary: 13% higher: 11% Source: G. Psacharopoulos and H. Patrinos, “Returns to Investment in Education: A Further Update”, World Bank Policy Research Working Paper 2881, September 2002 (social rates of return from Table 1).

28 Thus… Vaccination and other cost-effective child health promotion programs have a strong claim to be powerful instruments of economic growth, poverty reduction, and human betterment. But: A prerequisite is extensive coverage and equitable delivery and therefore a functional health system that can deliver. Source: David Bloom and David Canning, Harvard University

29 Main Take-Home Message: Immunization and other cost-effective child health promotion programs can be highly cost-beneficial tools for promoting both the health and wealth of nations Source: David Bloom and David Canning, Harvard University

46 Key health research areas to consider Cause-specific burden of disease studies  guide intervention-oriented research. Mother and child health, HIV/AIDS, TB Studies of disease determinants (SA and SSA) with an equity lens Clinical/field trials: –Efficacy trials –Program-relevant effectiveness trials Studies (including trials) of comprehensive, community-based approaches Health systems research, particularly on operational aspects and on evaluation

47 EDCTP aims to: accelerate the development of new clinical interventions to fight HIV/AIDS, tuberculosis and malaria build relevant capacities in developing countries for clinical trials-based evaluation of such interventions Budget: 200ME+200ME+200ME, of which 25% for capacity building, Cape Town selected as hosting institution of the African branch office of EDCTP Secretariat

48 Possible strategies for RSA-Norwegian health research Regional collaboration: SADC Other “South-South” collaboration, e.g. w. India Funding: EU/EDCTP: SA as a regional nodal point Research linked to postgraduate training and institutional strengthening in both (all) countries Management after 2009?: S&T/NRF and Research Council of Norway/Norwegian Centre for International Cooperation in Higher Education?
