Objetivo: comparar imagen corporal y riesgo de trastornos alimentarios (TA) en niños con sobrepeso/obesidad y normopeso. Muestra y Metodología: 92 niños/as de 9-12 años completaron un Cuestionario sociodemográfico y de sintomatología de TA, el Children’s Eating Attitudes Test (ChEAT)(Maloney, McGuire, & Daniels, 1988), y el Child/adolescent Silhouette Rating Scale (Collins, 1991). Fueron pesados y medidos por una nutricionista según normas de la Sociedad Argentina de Pediatría. Resultados: 7(7.6%) presentaron riesgo de bajo peso, 46(50%) normopeso, 24(26.1%) sobrepeso y 15(16.3%) obesidad. Se dividieron dos grupos según Índice de Masa Corporal: sobrepeso/obesidad (SO) y normopeso (NP). 56.52% del grupo NP considera que su peso es el adecuado; sin embargo 26.09% se ve un poco gordo y 32.61% desea pesar un poco menos. Si bien los niños de ambos grupos desean verse en promedio más delgados, la distancia entre cómo se perciben y cómo desean verse es superior en el grupo SO, indicando mayor insatisfacción con la imagen corporal. Se observaron puntajes más elevados en el ChEAT en el grupo SO en comparación con el grupo NP. Se halló una relación entre pertenencia a cada grupo y riesgo de TA. El 23.08% de los niños con SO y ninguno con NP presentó este riesgo.

Sample and Methodology: 92 children between 9-12 years old completed a Sociodemographic questionnaire wich inquires about symptoms of ED as well, the Children’s Eating Attitudes Test (ChEAT) (Maloney, McGuire, & Daniels, 1988) and the Child/Adolescent Silhouette Rating Scale (Collins, 1991). They were weighed and measured by a nutritionist according to the norms of the Sociedad Argentina de Pediatría. Results: 7(7.6%) were at risk of underweight, 46(50%) normal range, 24(26.1%) overweight and 15(16.3%) obese. They were divided in two groups according to Body Mass Index: Overweight/obesity(O) and normal range(NR). 56.52% of NR group believe that his weight is fine, but 26.09% states that he´s a little overweight and 32.61% wanted to weigh a little less. Although children of both groups want to be thinner on average, the gap between how they look and how they want to look is greater in group O, indicating greater body image dissatisfaction. Moreover, children in group O show higher rates in the ChEAT . A relationship between membership in each group and risk of ED was found. 23.08% of children with O and none with NR showed this risk.
