[Viewpoint] From epidemiological transition to modern cardiovascular epidemiology: hypertension in the 21st century
In 1971, Omran formulated the theory of epidemiological transition to explain the shift in mortality and disease patterns worldwide.1 The theory begins with the major premise that mortality is a fundamental factor in population dynamics. At the beginning of time was the age of so-called pestilence and famine. Mortality was high; life expectancy around 20–30 years; and famine, injuries, and infectious diseases were common causes of death. The first transition took place around 10 000 years ago which brought the world into the age of receding pandemics.
