Establishing method for juvenile height predication model

Abstract

The invention relates to an establishing method for a juvenile height predication model. The establishing method comprises the following steps of: tracking and testing height and bone ages per year of N juveniles from S years old to (S+M-1) years olds for M years, and recording life ages of the juveniles in those years; measuring height, at the age of (S+M) years old, of the N juveniles; constructing a sample set by utilizing the life ages, the height and the bone ages per year of the N juveniles from S years old to (S+M-1) years old; establishing a ternary linear-regression mathematical model by taking the life ages, the height and the bone ages per year of the N juveniles from S years old to (S+M-1) years olds as independent variables and utilizing the height, at the age of (S+M) years old, of the N juveniles as dependent variables; and utilizing a linear-regression analysis tool to obtain a ternary height predication model, at the age of (S+M) years old, of the juveniles through a least square method. The establishing method has the beneficial effects that: the condition that a height predication formula made by utilizing Chinese data is not provided in China for a long term is ended, so that the height predication model which is more suitable for the Chinese is obtained.

Description

technical field [0001] The invention belongs to the field of juvenile height prediction, and in particular relates to a method for establishing a juvenile height prediction model. Background technique [0002] It is of great significance to predict the adult height of adolescents in the childhood stage, which is of great significance in the evaluation of the growth and development of adolescents and in the scientific selection of athletes. At a certain time during the individual growth and development of children, use developmental indicators such as height and bone age to estimate their height at the end of their future growth, which is adult height prediction. The relationship between height, bone age and other developmental indicators and adult height is the basis of height prediction, so the prediction of adolescent height should rely on long-term follow-up research on adolescent developmental indicators. [0003] In the past, my country did not have tracking data on th...

Problems solved by technology

Due to the physical differences between the Asian population and the European and American population, the adult height of Chinese teenagers obtained by using the height prediction formula of Europe and the United States in the past is very inaccurate
