Health Transition & MDR-TB
Review
● DALYs
○ composite measure of global health
○ YLL-YLD
○ combines longevity and something about quality of life
Epidemiological transition theory:
● shift in global burden of disease from communicable (infectious) to non-communicable
(chronic) conditions
● communicable/infectious diseases: transmittable to host by outside source (vector, body
fluids, etc)
○ ex: ZICA is currently in the news
● non-communicable/chronic conditions: conditions “within host”, usually due to degeneration
(aging)
● Transition occurs over centuries of human history
● Health transition accompanied by demographic transition: decline in fertility rates and
increase in life expectancy
○ the demographic transition = generally aging populations
● “A long-term shift in mortality and disease patterns whereby pandemics of infection are
gradually displaced by degeneration and manmade diseases as the main causes of
morbidity and mortality” (Omran 1971)
● From “diseases of poverty” to “diseases of affluence"
● “Marks a fundamental change in main determinants of health… the point in economic
development at which the vast majority… gained access to the basic material necessities of
life” (Wilkinson p 39)
Explanations for the Epi Transition:
● medical advances, public health interventions
● McKeown hypothesis (review) — rising living standards —> decline in infectious diseases
mortality illustrates relationship between economic development and population health
● however, the impact of economic growth on health “levels off”; there is a point where
absolute material standards of living no longer explain population health outcomes
The Health Transition in Critical Perspective
● this transition is uneven; persistence of poverty, under-development & infectious disease
● underlying assumptions are problematic, reflect linear model of “development"
● the shift to chronic conditions (and the re/emergence of infectious conditions) are in fact due
to the conditions of “development"
● in many countries, the worse-off are bearing the burden of chronic diseases
● good thing to go through epidemiological transition

Document Summary
Combines longevity and something about quality of life. Shift in global burden of disease from communicable (infectious) to non-communicable (chronic) conditions. Communicable/infectious diseases: transmittable to host by outside source (vector, body fluids, etc) Ex: zica is currently in the news. Non-communicable/chronic conditions: conditions within host , usually due to degeneration (aging) Transition occurs over centuries of human history. Health transition accompanied by demographic transition: decline in fertility rates and increase in life expectancy. The demographic transition = generally aging populations. A long-term shift in mortality and disease patterns whereby pandemics of infection are gradually displaced by degeneration and manmade diseases as the main causes of morbidity and mortality (omran 1971) From diseases of poverty to diseases of affluence" Marks a fundamental change in main determinants of health the point in economic development at which the vast majority gained access to the basic material necessities of life (wilkinson p 39)
