Calculation of risk:
Health risk assessment is an estimate of whether an individual with a certain health characteristic will develop a certain disease or health condition within a certain period of time. The commonly used health risk assessment usually leads to death. Due to the development of technology and the change of health management requirements, health risk assessment has gradually expanded to disease-based risk assessment.
There are generally two methods for disease risk assessment and prevention. The first is based on a single risk factor and incidence, and the relationship between these single factors and incidence is expressed as relative risk, and the weighted score of each related factor is the risk of illness.
