Risk factor
Risk factor is a term used in the field of medicine and epidemiology to describe any attribute, characteristic or exposure of an individual that increases the likelihood of developing a disease or injury. Some examples of the more common risk factors include unhealthy diet, physical inactivity, and tobacco use.

Definition[edit]
A risk factor is a variable associated with an increased risk of disease or infection. Sometimes, the precise cause of the disease is not known, but certain factors are known to increase the likelihood of the disease. These risk factors can be categorized into two main types: modifiable and non-modifiable.
Modifiable risk factors[edit]
Modifiable risk factors are those that can be changed or controlled by the individual. These include lifestyle choices such as diet, physical activity, and tobacco and alcohol use. By making healthier choices, individuals can reduce their risk of disease.
Non-modifiable risk factors[edit]
Non-modifiable risk factors are those that cannot be changed by the individual. These include age, gender, and genetic predisposition. While these factors cannot be changed, understanding them can help individuals make informed decisions about their health.
Risk factor in epidemiology[edit]
In epidemiology, a risk factor is a variable associated with an increased risk of disease or infection. Epidemiologists often use observational studies to identify risk factors. These studies can be cross-sectional, case-control, or cohort studies.
