Background: This study not only analyzed how obesity and one's own subjective body perception have on adolescents’ satisfaction of their own body and self-esteem, but also the moderating effect of gender.
Methods: We carried out GLM (Generalized Linear Mode) to estimate the effects of adolescents’ obesity and subjective body perception on the satisfaction of their own body and self-esteem by using SPSS 20.0.
Results: Those who perceived their weight to be underweight among boys showed statistically lower satisfaction of their body and lower self esteem. In contrast, self perception of being underweight among girls statistically increased both satisfaction of their body and self esteem.
Conclusion: Self perception of being underweight statistically proved to lower one's satisfaction of their own body and self-esteem among boys, in contrast to girls.
