What are the four dimensions of disease study?

Molecular, tissue, organic, population.

What is the focus of epidemiology?

Disease frequency, distribution, health determinants in populations.

Frequency, distribution, determinants, population.

Studies diseases at a population level to prevent diseases.

People, host, environment; primary and secondary determinants.

Epidemiology, rooted in the Greek language, delves into disease patterns, causes, and distribution within populations, employing statistical methods and demographic analysis for preventive medicine collaboration.
Diseases exhibit complex origins involving internal and external factors interacting to create conditions like hypertension or lung cancer, highlighting the importance of understanding primary and secondary determinants in disease development.

The study of diseases can be approached through four dimensions: molecular, tissue, organic, and population, each utilizing different disciplines like molecular biology, immunology, pathological anatomy, and epidemiology.
Epidemiology, a discipline originating from Greek, focuses on studying disease frequency, distribution, and health determinants in populations, collaborating with preventive medicine and using statistics, mathematics, and demography.
Key terms in epidemiology include frequency (how often a disease occurs), distribution (where it appears geographically and in which populations), determinants (factors influencing disease appearance), and population (a group with common characteristics).
Epidemiology differs from clinical medicine by studying diseases at a population level, aiming to prevent diseases by understanding causes and comparing healthy and sick groups.
Diseases often have multifactorial etiology, with internal and external factors interacting synergistically or antagonistically, leading to diseases like hypertension or lung cancer.
Determinants influencing disease appearance or progression can be classified into three categories: people, host, and environment, with primary determinants being crucial for disease onset and secondary determinants having a minor effect or acting as predisposing factors.
