Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction.

This study examined prospective associations between 10-year-olds' weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls' increments in body dissatisfaction, the mere perception of being too heavy was associated with boys' poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls' weight-esteem, teasing targeted towards appearance was associated with boys' more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.
