Abstract
|
|
|
Objective: To analyze the incidence of obesity in adults aged 19?59 years in Korea and predict its trend in the future.
Methods: We considered a two-compartmental deterministic mathematical model Susceptible-Infected-Susceptible (SIS), a system of difference equations, to predict the evolution of obesity in the population and to propose strategies to reduce its incidence.
Results: The prevention strategy on normal-weight individuals produced a greater improvement than that produced by treatment strategies.
Conclusions: Mathematical model sensitivity analysis suggests that obesity prevention strategies are more effective than obesity treatment strategies in controlling the increase of adult obesity in Korea.
