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.
