Types of Epidemiology Studies

Epidemiology is the study of the distribution of health problems and their determinants in human populations. In this context, one of its aims is to study the impact of behavioral, occupational and environmental factors on health. An epidemiological study aims to analyze the factors which influence the frequency or distribution of diseases and other health phenomena in the populations exposed to these factors. Its objective is to attempt to establish an association between exposure to certain substances and the occurrence of disease. There are two main types of epidemiology studies, experimental and non-experimental. The non-experimental studies are also called observational studies.
