This study investigated the prevalence of weight control and binge eating behaviors in a sample of 767 adolescent girls aged 16–20 years, and the differences between adolescents with and without altered eating behaviors regarding anthropometric and body image variables and beliefs associated with eating disorders. Adolescents who engaged in unhealthy strategies were found to be at a higher risk of eating disorders, since these behaviors were accompanied by higher levels of drive for thinness and body dissatisfaction, as well as by beliefs associated with the importance of weight and body shape as a means of personal and social acceptance.
