Résumé:
In this paper, we propose a mathematical model based on employing social networks in supporting
the general health of obese people through positive behaviors related to nutrition and
physical activity within these networks. The proposed model is represented mathematically
by a non-linear time system of ordinary differential equations. We analyze the stability of
the equilibria with the negative and positive effects of social networks. Then, we perform
sensitivity analyses on our model to determine the relative importance of model parameters
to reduce complications due to obesity. Finally, numerical simulation results are obtained
and displayed in graphical profiles. The results of our model and the health ramifications are
then raised, discussed, and confirmed by other researchers’ results. This study is a theoretical
study and is thought to be useful for other work to do.
