Estudio de las características antropométricas y nutricionales de los adolescentes del núcleo urbano de Valladolid / Study of the anthropometric and nutritional characteristics of adolescents in the city of Valladolid

Objetivos: Descripción de las características antropométricas de una muestra de adolescentes de Valladolid junto al análisis de ingesta dietética del grupo de población. Material y métodos: Estudio de campo observacional descriptivo transversal, de una muestra de 557 adolescentes (14 - 18 años), seleccionada por muestreo probabilística de entre 6 institutos públicos y privados, de distintos barrios de Valladolid. Se realizó un cuestionario de frecuencia de consumo junto a la medición antropométrica. La clasificación de los individuos se realizó mediante el cálculo del Z-score del Índice de Masa Corporal (IMC),los puntos de corte para el IMC de Cole y criterios de la International Diabetes Federation (IDF). El análisis nutricional se realizó mediante un enfoque probabilístico y el índice de adecuación nutricional. Resultados: El exceso de peso es similar en ambos sexos(17%), sin emabargo existe un 15,2% de prevalencia de bajo peso entre las mujeres estudiadas, frente al 4,5% en varones(p<0,005). El 1,3% presentan riesgo de padecer síndrome metabólico. El consumo energético se distribuye: 30-32% lípidos, 45% hidratos de carbono y 16-17% proteínas. La valoración nutricional refleja probable déficit de consumo en yodo, zinc, vitaminas A y E. Conclusiones: La prevalencia de obesos está próxima ala de otras series, pero la prevalencia de sobrepeso es inferior. Es muy importante el porcentaje de mujeres con IMC por debajo de lo normal para su edad y sexo. Existe un exceso de aporte proteico, de grasas saturadas y de colesterol, con un déficit en el consumo de hidratos de carbono, yodo, zinc y vitaminas A y E (AU)

Objectives: A description of the anthropometric characteristics of a sample of adolescents from Valladolid and the analysis of dietary intake of the population. Materials and methods: Observational study of descriptive cross-field of a sample of 557 adolescents (14 - 18years) by probabilistic sampling from 6 public and private, in different districts of Valladolid. We carried out a food frequency questionnaire with anthropometric measurements. The classification of individuals was by calculating the Z-score of body mass index (BMI), the Cole`s cut off points for BMI and criteria of the International Diabetes Federation (IDF). Nutritional analysis: probabilistic approach and the nutrient adequacyratio. Results: Excess weight is similar in both sexes (17%),but there is a 15.2% prevalence of underweight among the women studied, compared to 4.5% in males (p<0.005). 1.3% risk of having metabolic syndrome. Energy consumption is distributed: 30-32% fat, 45% carbohydrates and 16-17% protein. The nutritional deficiency likely reflects consumption in iodine, zinc, vitamins A and E. Conclusions: The prevalence of obesity is close to that of other series, but the prevalence of overweight is lower. It is very important percentage of women with a BMI below normal for their age and sex. There is an excess of protein intake of saturated fat and cholesterol, with a deficit in the consumption of carbohydrates, iodine, zinc and vitamins A and E (AU)
