RESUMO
Objetivo Evaluar los cambios en los hábitos de alimentación y actividad física así como la prevalencia de obesidad y sobrepeso que se han producido en una cohorte de alumnos entre 1° y 4° de secundaria tras una intervención no estructurada de educación para la salud. Método Estudio descriptivo longitudinal. Se recogieron variables antropométricas y de hábitos de alimentación, ocio y actividad física a los alumnos de 1° de ESO (n=61) y se midieron de nuevo cuando cursaban 4° de ESO. Se realizo un analisis apareado de los datos mediante el test Mc Nemar-Bowker. Durante el periodo de estudio se realizaron sesiones educativas sobre alimentación saludable y actividad física. Resultados La prevalencia de sobrepeso ha mejorado significativamente (de 14,8% a 3,7%) y se ha incrementado el nivel de actividad física. No se han detectado cambios en la calidad del desayuno ni en la calidad de la dieta mediterránea. Conclusiones Algunos de los aspectos estudiados han mejorado sin poderse atribuir esa mejora a las sesiones educativas realizadas. Conocer y analizar los hábitos de vida saludable de los adolescentes permitirá planificar intervenciones realistas, adaptadas al entorno concreto, estructuradas y continuadas en el tiempo, que aborden las áreas de conocimientos, habilidades y emociones y que vayan dirigidas no sólo a los jóvenes sino también a sus familias, al entorno interno del centro educativo y a la coordinación de los recursos comunitarios que permita un abordaje coordinado (AU)
Objective To evaluate the changes in dietary habits and physical activity, as well as the prevalence of obesity and overweight that have occurred in a cohort of 1st and 4th year secondary school pupils after non-structured health education activities. Method A descriptive, longitudinal study, in which anthropometric variables, dietary habits, leisure and physical activity were collected in the 1st year secondary school pupils (n=61), and they were measured again when they were in the 4th year. The differences between the two school years were analysed using the Mc Nemar-Bowker Test. During the period of the study educational sessions were given on healthy eating and physical activity. Results The prevalence of overweight decreased significantly (from 14.8% to 3.7%) and the level of physical activity has increased. No statistical differences were detected in the quality of breakfast or in the quality of the Mediterranean diet. Conclusions Some of the aspects studied have improved without being able to attribute this improvement to the educational sessions given. To determine and analyse the healthy living habits of adolescents would enable us to plan realistic interventions, adapted to the particular environment. They should be structured and continuous over time and approach areas of knowledge, skills and emotions, and directed, not only at the young people, but also their families, the internal environment of the educational centre. There should be coordination of community resources in order to make a coordinated approach (AU)
