Epidemiological Transition Flashcards
What does the model suggest ?
As socio economic development occurs over time there is a transition from infectious diseases to chronic and degenerative diseases
Why does this transition occur ?
Modernisation from lic to HIC
Demographic transition
Medial advances
Diseases prevention
Sickness treatment
Where are the 3 stages ?
What was the stage added called ?
- Age of pestilence and famine
- Age of reversing pandemics
- Age of degenerative/ manmade diseases
- Age of delayed degenerative diseases
Age of pestilence and famine
Mortality high / fluctuates
Prevent sustained pop growth
Life expectancy 20-40 yrs
Wars/ famine / epidemics
Age of receding pandemics
Mortality declines
Epidemics less frequent
Life expectancy increases
Pop growth sustained/ rises
Medical advances/ healthcare
LE 30-50 yrs
What decreases rate of epidemics during receding pandemics ?
Clean water
Penicillin
Age of degenerative and man made diseases
Mortality decreases / low level
Non communicable diseases
Life expectancy increases more than 50 years
Increase in fertility
Increase in pop growth
Age of delayed degenerative diseases
Decline death rates
Life expectancy 70-80
Non communicable but delayed until older ages as new prevention treatments
Diseases in infection & famine
Communicable infections
HIV / aids
Nutritional deficiencies
Diseases in reducing pandemics
Reduce number of infectious diseases
Strokes
Heart attacks
Diseases in man made and degenerative diseases
High blood pressure Obesity Cancers Heart diseases Dementia

What did Omran discovered about model ?
There was variations in pattern / pace and pop change within transition so he identified 3 types of model
