According to Masten and Coatsworth (2001), obesity leads to social stigmatization that makes it difficult for the affected students to compete favorably with the rest of the students and attain higher grades. It is due to the fact that it impacts upon their esteem and hence undermines active participation in classroom and field activities.
In addition, it has negative health implications like diabetes that prevents the affected students from participating fully in academic activities. Indirectly, it promotes behavioral constrains such as violence, bullying and drug use and abuse. In this regard, Eliot (1998) indicates that obese students tend to have pronounced mood disorders that partly stem from stigmatization that the society accords them. As such, they resort to violence as a protective measure or drug use and abuse in order to have temporary relief from the perceived hostile school environment.
