Predictive Equation for Body Fat Percentage in College Students Based on Artificial Neural Network

The aim of this study is to establish the predictive equation for body fat percentage (BFP) among university and college students, trying to analyze the relationship between body mass index (BMI) and BFP by using artificial neural networks (ANN) and big dataset of 1201 contemporary college students of China.The results showed that BFP productional functions structured by ANN with BMI have the accuracy of higher than 91%.The fitting precision of quadratic equation is higher than that of linear equation in both genders.The established equation provides a more scientific basis for nutritional assessment, health management and risk prediction of related diseases of contemporary college students in China.
