A risk factor a) precedes the outcome, and b) when used it divides a population into high risk and low risk subgroups. Risk factors may be population specific. They may be fixed markers, variable markers or causal risk factors.
A risk factor is a characteristic, condition or habit that increases a person’s chances to develop a particular disease or injury, for example, physical inactivity may, over time, contribute to weight gain, high blood pressure and high cholesterol levels.
