Study Notes
Epidemiologic Transition Model
- The first stage of the epidemiologic transition model is characterized by high and fluctuating mortality rates, precluding sustained population growth.
Focus of Epidemiologic Transition
- According to Abdel Omran, the main focus of the epidemiologic transition is the shift from infectious to chronic diseases.
Phases of Epidemiologic Transition Model
-
In the third phase of the epidemiologic transition model, the mortality rates from infectious diseases continue to decline, while the rates from chronic diseases start to rise.
-
The fourth phase of the epidemiologic transition model is characterized by a decline in mortality rates from chronic diseases, resulting in a steady increase in life expectancy.
Life Expectancy at Birth
- In the first stage of the epidemiologic transition model, the average life expectancy at birth is very low, typically around 20-40 years.
