Abstract

 

Lifestyle affects the health of children and adolescents, especially those living with socio-economic disadvantages. The purpose of this study was to evaluate nutritional status, level of fitness, and diet in children and adolescents from different socio-economic environments. To evaluate nutritional status and nutritional habits, Body Mass Index Z-score, Waist-to-Height Index and the Mediterranean Diet Quality Index, were chosen. To measure physical fitness, Eurofit battery was used. Participants were 290 healthy children and adolescents of two groups. Group 1 (78) was part of a social integration project through sport; group 2 (212) belonged to a private school with a high socio-economic status. Differences between groups were found in the nutritional status and physical fitness tests. There were no differences in the total score of the Kid Med Test (p=.42), but data suggested a better quality of food consumption in group 2. Even though both groups exhibited healthy values, results were slightly more favorable for speed of movement and flexibility (p<.05), and for diet habits (better intake of olive oil, less sweet consumption, p < .05) in the group 2. The study, even with limitations, shows that there is still room for equal opportunities in promoting the quality of life of young people. 

Resumen: El estilo de vida afecta a la salud de los niños y adolescentes, especialmente a los que viven en riesgo de exclusión social y económica. El propósito de este estudio fue evaluar el estatus nutricional, el nivel de condición física y la dieta en niños y adolescentes de diferentes entornos socioeconómicos. Para evaluar el estatus nutricional y los hábitos nutricionales, se eligió el índice de masa corporal z-score, el índice cintura-estatura y el índice de calidad de la dieta mediterránea. Para medir la aptitud física, se utilizó la batería Eurofit. Los participantes fueron 290 niños y adolescentes sanos de dos grupos. El grupo 1 (78) formaba parte de un proyecto de integración social a través del deporte; el grupo 2 (212) pertenecía a un colegio privado de alto nivel socioeconómico. Se encontraron diferencias entre los grupos en las pruebas de estatus nutricional y de aptitud física. No hubo diferencias en la puntuación total del Kid Med Test (p=.42), pero los datos sugirieron una mejor calidad del consumo de alimentos en el grupo 2. Aunque ambos grupos presentaban valores saludables, el grupo 2 obtuvo mejores resultados en la velocidad de movimiento y la flexibilidad (p<.05), y en los hábitos dietéticos (mejor consumo de aceite de oliva, menos consumo de dulces, p <.05). El estudio, aun con limitaciones, muestra que todavía hay espacio para la igualdad de oportunidades en la promoción de la calidad de vida de los jóvenes.
