El presente estudio pretende explorar preocupaciones y actitudes respecto al peso y la imagen corporal que presentan mujeres adolescentes con riesgo de trastorno alimentario (RTA). Las adolescentes con RTA forman parte de una muestra mayor conformada por 202 mujeres y 106 varones, entre 13 y 19 años de escuelas medias de CABA (Proyectos UBACyT y UBANEX). Se realizó un estudio de doble fase con el fin de detectar trastornos alimentarios (TA) y RTA mediante instrumentos autoadministrables y entrevistas individuales. Finalmente, se identificaron tres grupos: adolescentes con TA, con RTA y sin TA ni RTA. En este estudio se incluyen únicamente las 17 adolescentes RTA. Si bien todas las adolescentes con RTA presentan un peso saludable, la mayoría se considera “gorda” o “con exceso de peso” y desearía pesar en promedio, 5.54 kg menos. Además, realizan dietas y actividad física excesiva para bajar de peso. Presentan gran preocupación por el peso y la silueta encontrándose altamente influenciadas respecto de los modelos estéticos que se divulgan en los medios masivos de comunicación. El estudio de población con RTA resulta fundamental para poder diseñar e implementar programas de prevención específicos.
