The developments of modern healthcare and medicine, such as antibiotics, drastically reduce infant mortality rates and extend average life expectancy which, coupled with subsequent declines in fertility rates, reflects a transition to chronic and degenerative diseases as more important causes of death. The theory of epidemiological transition ...
This describes the shift from high fertility and high mortality in underdeveloped societies to lower fertility and mortality rates as a result of development. [3] Then around 1970, the Epidemiological transition framework was used to characterize changes in the health of societies during development. [4]

For the full specification of the model, the arrows should be labeled with the transition rates between compartments. Between S and I, the transition rate is assumed to be (/) / = /, where is the total population, is the average number of contacts per person per time, multiplied by the probability of disease transmission in a contact between a susceptible and an infectious subject, and / is ...
Nutrition transition is the shift in dietary consumption and energy expenditure that coincides with economic, demographic, and epidemiological changes. Specifically the term is used for the transition of developing countries from traditional diets high in cereal and fiber to more Western-pattern diets high in sugars, fat, and animal-source food.
Epidemiological (and other observational) studies typically highlight associations between exposures and outcomes, rather than causation. While some consider this a limitation of observational research, epidemiological models of causation (e.g. Bradford Hill criteria) [7] contend that an entire body of evidence is needed before determining if an association is truly causal.

In much of his writings, he calls for the learning of a "dying art", which he describes as becoming necessary at a time when death comes too late, rather than too early. This phenomenon is often referred to as the 'fourth phase' of the epidemiological transition . [ 3 ]
