Principles and techniques of health risk assessment

Health risk assessment includes three basic modules: questionnaire survey, risk calculation and assessment report. Today, most health risk assessments have been computerized. Questionnaire survey is an important means to collect information in health risk assessment. According to the focus and purpose of the assessment, the required information will be different.

Generally speaking, the main components of the questionnaire include: 1) physiological and biochemical data, such as height, weight, blood pressure, blood lipid and so on. 2) Lifestyle data, such as smoking, diet and exercise habits; 3) Personal or family health history; 4) Other risk factors, such as mental stress; 5) Information about attitude and knowledge. 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. Common health risk assessment is generally based on the risk of 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. Because the latter can make individuals understand the role of risk factors more effectively. And control measures can be implemented more effectively and the cost can be reduced.

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. Because the scheme is simple and practical, it does not need a lot of data analysis, and it is the main risk assessment method in the early stage of health management development. Typical evaluation methods are Carter Center and American Diabetes Association.

The second method is based on multi-factor analysis, that is, the relationship model between disease risk and risk factors is obtained by statistical probability theory. In order to include more risk factors and improve the accuracy of evaluation, this data-based model has developed greatly in recent years. In addition to the common multiple regression, there are neural network methods based on fuzzy mathematics and Monte Carlo models. The typical representative of this method is Framingham's coronary heart disease model, which is based on prospective research and is widely used. The types of health risk assessment reports and the combination of various reports vary widely. In a better case, the evaluation report includes the personal report of the assessed and the crowd report summarizing all the assessed. Meanwhile, corresponding to the purpose of health risk assessment, personal reports usually include the results of health risk assessment and health education information. A population report generally includes an overview of the demographic characteristics of the assessed group, a summary of health risk factors, and suggested intervention measures and methods.

There are many forms to evaluate newspapers. It can be predicted that with the continuous popularization of the Internet, publishing educational information through the Internet will become an important form of education because of its wide audience, fast update and strong accessibility.
