ABSTRACT

Background:

Dietary treatment for obese adolescents should aim to ensure adequate growth and development, by reducing excessive fat mass accumulation, avoiding loss of lean body mass, improving well-being and self-esteem and preventing cyclical weight regain. The aim of this article is to describe the dietary intervention design and the methods used to evaluate nutritional knowledge and behavior in the EVASYON study (Development, implementation and evaluation of the efficacy of a therapeutic programme for overweight/obese adolescents). Methods/

design:

EVASYON is a multi-centre study conducted in 5 Spanish hospital settings (Granada, Madrid, Pamplona, Santander and Zaragoza), where 204 overweight/obese Spanish adolescents were treated in groups of 9 to 11 subjects over 20 visits. The study was implemented in two stages an intensive, calorie-restricted period for the first 9 weeks, and an extensive body-weight follow-up period for the last 11 months. A moderate energy intake restriction was applied in the intensive period according to the degree of obesity, on the basis of a balanced diet supplying 50-55% of daily energy as carbohydrates; 30-35% as fats and 10-15% as proteins. In the intensive period, adolescents were prescribed both a fixed full-day meal plan for the first three weeks and a full day meal plan with different food-choices for 6 weeks. Later, adolescents received a flexible meal plan based on food exchanges for the follow-up period until the end of the trial. Data on food intake, dietary and meal-related habits and behavior were collected by means of dietary questionnaires. To analyse nutritional knowledge, adolescents were examined regarding nutrient concepts and food adoitems for a healthy diet with the appropriate tools. Participants were given nutritional information with complementary teaching material, which was available on the EVASYON website (www.estudioevasyon.com).

Discussion:

The dietary intervention of the EVASYON programme with a moderate calorie restriction for a limited period of time could be a good strategy in treating overweight and obese adolescents and that will be tested further. Moreover, combining fixed plan with free-choice menus may help adolescents and their families to make right decisions for every day meals (AU)
RESUMEN
Antecedentes El tratamiento dietético para los adolescentes obesos debería asegurar el crecimiento y desarrollo adecuados al reducir la acumulación excesiva de masa grasa, evitar la pérdida de masa magra corporal, mejorar el bienestar y la autoestima y prevenir la ganancia cíclica de peso. El objetivo de este artículo es el de describir el diseño de la intervención dietética y los métodos empleados para evaluar el conocimiento y la conducta nutricionales del estudio EVASYON (Desarrollo, implantación y evaluación de la eficacia de un programa terapéutico para adolescentes con sobrepeso/obesidad). Métodos/

diseño:

EVASYON es un estudio multicéntrico realizado en 5 hospitales españoles (Granada, Madrid, Pamplona, Santander y Zaragoza), en el que se trató a 204 adolescentes españoles con sobrepeso/obesidad en grupos de 9 a 11 individuos a lo largo de 20 visitas. El estudio se implantó en dos etapas un período intensivo de restricción calórica durante las 9 primeras visitas y un período extensivo de seguimiento del peso corporal durante los últimos 11 meses. Se aplicó una restricción moderada de consumo de energía durante el período intensivo en función del grado de obesidad, sobre la base de una dieta equilibrada que aporta el 50-55% de la energía diaria en forma de carbohidratos; 30-35% como grasas y 10-15% como proteínas. En el período intensivo, se prescribió a los adolescentes un régimen de comidas fijo para todo el día durante las 3 primeras semanas y un plan de comidas para todo el día con diferentes opciones durante 6 semanas. Posteriormente, los adolescentes recibieron un régimen de comidas flexible sobre la base de los intercambios de alimentos durante el período de seguimiento hasta el final del ensayo. Se recogieron los datos de consumo de alimentos, dietéticos y hábitos relacionados con las comidas mediante cuestionarios de dieta. Para analizar el conocimiento nutricional, se examinó a los adolescentes con respecto a conceptos de nutrición y alimentos concretos para una dieta sana con las herramientas adecuadas. Se proporcionó a los participantes información nutricional con material educativo complementario que estaba disponible en la página web del estudio (www.estudioevasyon.com). 


Discusión:

La intervención dietética del programa EVASYON con una restricción calórica moderada durante un período de tiempo limitado podría ser una buena estrategia para el tratamiento de los adolescentes con sobrepeso y obesidad y se probará más adelante. Además, el combinar el plan fijo con menús de elección libre podría ayudar a los adolescentes y sus familias a tomar las decisiones correctas para las comidas de todos los días (AU)
