Risk factors for body dissatisfaction in adolescent boys and girls: a prospective study.

Objective: Despite evidence that body dissatisfaction predicts the onset of eating pathology and depression, few prospective studies have investigated predictors of body dissatisfaction.

Method: We examined risk factors for body dissatisfaction using prospective data from 531 adolescent boys and girls.

Results: Elevations in body mass, negative affect, and perceived pressure to be thin from peers, but not thin-ideal internalization, social support deficits, or perceived pressure to be thin from family, dating partners, or media, predicted increases in body dissatisfaction. Gender moderated the effect of body mass on body dissatisfaction and revealed a significant quadratic component for boys, but not girls. Gender also moderated negative affect.

Discussion: Results support the assertion that certain sociocultural, biologic, and interpersonal factors increase the risk for body dissatisfaction, but differ for boys and girls. Results provided little support for other accepted risk factors for body dissatisfaction.
