The invention discloses a
disease risk prediction method and
system based on
big data analysis, and relates to the technical field of
disease risk prediction. The method comprises the steps of obtaining multi-
source data, and performing data cleaning,
feature selection and data
standardization processing; marking and labeling the collected data, constructing a
disease risk prediction model through
supervised learning, and performing real-time prediction and dynamic updating; the comprehensive
disease risk value of the patient is calculated according to the multiple indexes, and abnormal early warning and personalized intervention including health suggestion, follow-up visit management and psychological support are carried out. The
system comprises a
data acquisition module, a screening module, a risk prediction module, an evaluation module, an abnormity early warning module and a control module. According to the
system, through multi-
source data acquisition and intelligent
processing, accurate prediction and comprehensive evaluation of disease risks are realized, prediction accuracy is improved,
personalization of health management is enhanced, and timely early warning and
disease risk reduction are facilitated. According to the invention, the early discovery rate and prevention effect of diseases can be improved, and the medical cost is reduced.
