Health risk assessment is a key technical part in the process of health management, which can only be achieved through health management. It is the first step of chronic disease prevention, also known as risk prediction model. Based on a large number of personal health information collected, it analyzes and establishes the quantitative relationship between lifestyle, environment, heredity and other risk factors and health status, predicts the possibility of an individual suffering from a certain disease or dying from a certain disease in a certain period of time, and accordingly provides targeted control and intervention according to the needs of the crowd, thus helping the government, enterprises, insurance companies and individuals to achieve the maximum health effect at the lowest cost.
The most commonly used method of health risk assessment is multi-factor model method, which is based on multi-factor mathematical analysis, that is, the relationship model between disease risk and risk factors is obtained by using statistical probability theory, which can contain multiple risk factors at the same time, and the commonly used methods are multiple regression (logistic regression and Cox regression).
