Abstract

Adolescent obesity has a high risk of developing into adult obesity and may cause many psychological problems. This paper aims at giving a mathematical model for the obesity of Korean adolescents and predicting how much the prevalence of obesity among adolescents will increase using real data. We estimate that the obesity rate of boys will increase until about 28 ~ 29% in 2025.
