ABSTRACT

Introducción: La obsesión por la delgadez y la insatisfacción corporal pueden llevar a las adolescentes a seguir dietas sin supervisión, lo que podría asociarse además a conductas riesgosas de control de peso, tales como ayuno, vómitos, uso de diuréticos y laxantes. El objetivo fue explorar conductas de control de peso en adolescentes dietantes y relacionarlas con insatisfacción corporal (IC) y obsesión por la delgadez (DT). Pacientes y Método: Estudio transversal en 439 adolescentes de colegios públicos de Valparaíso diseñado para indagar conductas de control de peso riesgosas a través de escalas de IC y DT del Cuestionario de Trastornos Alimentarios (EDI-2), comparando dietantes y no dietantes. Resultados: El 43% había realizado dieta sin supervisión médica. Las dietantes presentan valores superiores en DT e IC. El 29,6% de ellas presenta restricción alimentaria de riesgo moderado a alto, tomando como base el criterio de expertos, y se encuentran diferencias en la presencia y severidad de las conductas purgativas de control de peso entre los dos grupos estudiados. Conclusiones: Un tercio de las adolescentes estudiadas hacen dietas sin supervisión profesional, presentan mayor IC y DT y conductas riesgosas de control de peso. Aquellas con sobrepeso y obesidad realizan dietas más restrictivas y conductas de control de peso más riesgosas.


Introduction: Obsession with thinness and body dissatisfaction can lead adolescents to follow unsupervised diets, which could result in risky weight control behaviors such as fasting, vomiting, use of diuretics and laxatives. The aim of the current study is to examine weight control behaviors in dieting adolescents and relate them to body dissatisfaction (BD) and obsession with thinness (OT). Methods: A cross-sectional study was conducted on 439 adolescents from Valparaiso public schools to investigate risky weight control behaviors due to BD and OT scales from the Eating Disorders Inventory-2 (EDI-2), comparing restrained eaters and non-restrained eaters. Results: A total of 43% adolescents had followed a weight loss diet without medical supervision. The dieters had higher BD and OT values. Moderate to severe food restriction, based on expert judgment, was observed in 29.6%, and differences in the presence and severity of purging behaviors were found between the 2 groups. Conclusions: One third of the adolescents studied followed diets without professional supervision and had higher BD and OT values, as well as risky weight control behaviors. Overweight and obese adolescents followed more restrictive diets and developed riskier weight control behaviors.
