Functional Analysis of Childhood BMI based on Simplicial Band Depth

This paper mainly studied the relationship between obesity and BMI. BMI is the ratio of height to weight and measures a person’s health. In this paper, height and weight data of obese children from 2 to 18 years old in local hospitals were collected. The linear regression method was used to find the correlation between BMI and children’s health degree, and the regression curve between age and BMI was plotted. This paper supplemented the vacancy of BMI study on children, and a complete BMI curve could be obtained for each child according to the curve, so as to predict possible health problems of children in advance
