Self-Reported versus Measured Height, Weight and Body Mass Index in Spanish Mediterranean Teenagers: Effects of Gender, Age and Weight on Perceptual Measures of Body Image

Background: To have a good physical appearance is a determining factor by which adolescents show a tendency to worry excessively about their weight. The aim of this work is to study the possible relationship between actual and perceived body weight, how it is considered and what strategies are followed for weight control among adolescents residing in Valencia. Methods: A sample of 568 students, 325 girls and 243 boys, aged 14–20 years, were selected from public high schools in Valencia. Their height and weight were used to calculate their actual body mass index (BMIO). The subjective perception of their physical measurements (BMIS) was evaluated by means of a questionnaire. The statistical treatment of data was done with commercially available software. Results: There is a relatively large proportion of underweight subjects among the participants of the survey. Differences between the BMIO and BMIS indicate a misperception of height (overestimated) and weight (underestimated) that is greater in girls than in boys. Girls tend to undergo restrictive dietary measures when they consider themselves overweight. A general lack of knowledge about adequate weight was observed. Conclusion: Valencia teenagers show a poor knowledge of their body size and of the weight that should be adequate for their age and tallness.Background: To have a good physical appearance is a determining factor by which adolescents show a tendency to worry excessively about their weight.

Papel de las leguminosas en la alimentación actual

Resumen En la alimentacion humana y animal se utilizan hasta 150 especies de leguminosas, de las que las mas relevantes para el consumo humano son judias, lentejas, guisantes, garbanzos, habas y cowpeas. En su composicion interesa destacar los contenidos de proteinas, de hidratos de carbono de asimilacion lenta, de minerales (calcio, hierro, cinc), fibra (soluble) y algunos componentes bioactivos minoritarios. El consumo humano de legumbres es menor en Europa que en otras regiones del mundo y muestra una amplia variabilidad. La posibilidad de utilizar legumbres cocidas, listas para su uso, facilita el aumento de su consumo en el hogar y la adaptacion a los cambios sociales, economicos y culturales. El cocinado mejora el perfil nutricional de las judias, ya que reduce componentes toxicos termolabiles y oligosacaridos manteniendo el contenido en proteina y fibra. La OMS recomienda el consumo de legumbres para disminuir el riesgo de enfermedades asociadas a la alimentacion (p. ej., diabetes mellitus tipo 2, obesidad). En recomendaciones dieteticas recientes para la poblacion americana, se destaca la importancia del consumo de judias (incluidas en el grupo de hortalizas y en el de proteinas). Las distintas legumbres muestran un contenido de nutrientes y otros compuestos bioactivos diferentes, por lo que interesa conocer el efecto de su consumo sobre todo en relacion con afecciones cronicas. En Espana hay numerosas variedades de judias, de las cuales se han seleccionado dos para analizar su composicion y valorar su efecto en la glucemia y la insulinemia de diabeticos tipo 2. Los principales resultados se comentan en el articulo.
