COHORT STUDY Meaning and
Definition
-
A cohort study is a type of observational research design used in medical, epidemiological, and social sciences to examine the relationship between various factors and the development of a particular outcome. In this study design, a group of individuals, known as a cohort, is followed over a period of time to determine the occurrence of a specific event, such as disease incidence or the occurrence of an adverse health outcome, and to investigate the factors associated with it.
This type of study is generally conducted by selecting a sample of participants who are initially free from the outcome being studied, and then monitoring their progress over time. Cohort studies can be either prospective or retrospective, depending on the direction of data collection. In prospective cohort studies, data is collected from the participants going forward in time, while retrospective cohort studies collect data from past records and follow the participants from a specific point in time to the present.
Cohort studies provide valuable information about the natural history of diseases, risk factors, and potential causal relationships. They allow researchers to observe the exposure and follow its effects over time, providing insights into the development and progression of the outcome of interest. By measuring exposure and outcome variables in a large sample of participants, cohort studies can provide reliable estimates of disease risk and can evaluate the impact of various factors on health outcomes.
Overall, cohort studies are a crucial research tool in understanding the etiology, prevention, and treatment of various diseases, as they enable the investigation of factors that contribute to the occurrence and development of health-related outcomes in a real-world setting.

Etymology of COHORT STUDY
The word "cohort" originates from the Latin word "cohors", which referred to a division of the Roman army, consisting of about 600 soldiers. Over time, the term "cohort" came to represent a group of people who share something in common or are part of a specific population.
The term "cohort study" emerged in the field of epidemiology, where researchers aimed to understand the causes and effects of diseases. In a cohort study, a group of individuals with similar characteristics or shared exposure to a risk factor is followed over time to examine the incidence of a particular disease or the outcomes associated with it. The term "cohort" in this context refers to the group of participants being studied, reflecting its original meaning of a group with a common characteristic.
