Method for predicting age by using blood marker

Abstract

The invention relates to the field of biological information, and discloses a method for predicting age by using a blood marker, which comprises the following four steps of: collecting blood marker data, preprocessing the data, establishing and evaluating a model and testing the model. Compared with other methods and markers, the method has the advantages that the blood marker serves as an evaluation object of the physiological age, the individual aging condition can be reflected more comprehensively, the aging level can be explained more comprehensively, meanwhile, the selected blood marker is predicted through the machine learning model, the process is more intelligent, and the result is more accurate; the selected blood marker, namely a blood biochemical index, is the most common indexin clinical and physical examination institutions, and is low in acquisition difficulty, low in cost and high in interpretation degree.

Description

technical field [0001] The invention relates to the field of biological information, in particular to a method for predicting age using blood markers. Background technique [0002] Aging is an inevitable life stage of an individual, and a continuous, dynamic and slow stage after biological development and maturity. In this stage, individual function declines, physiological structural components gradually degenerate, and a series of Degenerative diseases, such as senile bone hyperplasia, Alzheimer's disease (senile dementia), Parkinson's syndrome, etc. Aging is closely related to disease and death because of the decline in organ function and the changes at the cellular and molecular levels that accompanies aging and progressively affects health. In recent years, research on individual aging has also become a hot research field in life sciences. Aging varies greatly among individuals, and the aging level and speed of various systems and organs of the same individual are not ...

Problems solved by technology

[0005] Existing methods for predicting an individual's age only target a certain organ or tissue of the individual, lacking an overall description and explanation of individual aging, and unable to fully reflect individual aging. It is difficult and costly to obtain the indicators that need to be detected in the method of measuring aging and individual age through substances, telomere length, number of immune cells and response effect. Therefore, a method of predicting age using blood markers is designed, which will be used clinically. The more common and easier-to-obtain blood markers can be used as the characteristic value of predicting the individual's physiological age, and can also describe the individual's aging situation more comprehensively, which has practical significance and good application prospects
