Body composition calculation method based on bioelectrical impedance, device, computer equipment and storage medium

Abstract

The invention discloses a body composition calculation method based on bioelectrical impedance, a device, computer equipment and a storage medium. Firstly, characteristic parameters are selected; then, body composition training is carried out, including: (1) establishing a training sample database; (2) taking temporary samples and establishing a mathematical model; (3) training the mathematical model by a partial least squares method to solve the problem of multiple correlations between the characteristic parameters; and finally, the samples to be detected are input into the trained body composition mathematical model, and the body composition is obtained through analysis and calculation. The invention can accurately find influencing factors that affect the body composition, and avoids incorporating unnecessary body characteristic parameters into the body composition calculation or slipping away important body characteristic parameters. The use of the partial least squares method can avoid the multiple correlations between independent variables, and can complete the calculation under the condition of small sample size, with higher calculation accuracy than the calculation accuracyof multiple linear regressions.

Description

technical field [0001] The invention relates to a human body composition calculation method, device, computer equipment and storage medium applied to a human body composition analyzer, and belongs to the technical field of human body composition detection. Background technique [0002] With the improvement of people's living standards, the problem of obesity has become more and more serious. People are also gradually aware of the dangers of obesity, and are more concerned about whether body composition such as body fat, protein, and muscle is within a healthy range. Therefore, an accurate, simple and fast method for measuring body composition is very necessary, which can help the measurer to detect his own health status. [0003] Over the past few decades, many national experts and scholars have adopted many methods and developed many body composition analysis equipment for measuring body composition. The main methods are: underwater weighing method, air substitution metho...
