Desarrollo de un programa informático para estudios nutricionales

Se desarrollo el programa informatico Interfood v. 1.3 para procesar la informacion alimentaria y generar datos sobre el consumo dietetico -en terminos de alimentos, nutrientes y sustancias fitoquimicas- validos para realizar estudios nutricionales y epidemiologicos. El programa se basa en tres componentes fundamentales: el cuestionario de frecuencia de consumo alimentario (CFCA); una base de datos de alimentos frecuentes y su contenido en 131 compuestos (macro y micronutrientes y sustancias fitoquimicas); y una base de datos relacional que asocia la informacion del CFCA con la base de datos de alimentos. De esta forma, el programa informatico Interfood calcula la cantidad de cada uno de los alimentos y los nutrientes y las sustancias fitoquimicas que una persona consume por dia, semana y mes. Interfood es un programa de codigo abierto, por lo que sus bases de datos se pueden modificar y actualizar de acuerdo con las necesidades de la investigacion. Este programa ya ha demostrado su utilidad en diversas investigaciones nutricionales y epidemiologicas.

Agroecología en la escuela y calidad de vida relacionada a la salud de los adolescentes

The study aimed to evaluate the contribution of school agroecology to the quality of life related to health of adolescents of a school of Cordoba, Argentina. Feasibility study. It was a study quasi- experimental whit control group carried out in a middle-level public school. The sample consisted of 58 adolescents in the intervention group and 77 in the control group. After the intervention increased consumption of agro-ecological food (from 26% to 74% p<0,05). Changes were detected in acquired knowledge about agroecology in the classroom level going from 37% to 63% (p< 0,05). Positive changes detected in awareness with the environment and relationship (p<0,05). It was evidenced that the implementation of school agroecology can provide resolutive contributions to some of the problems the health related quality of life of adolescents.The study aimed to evaluate the contribution of school agroecology to the quality of life related to health of adolescents of a school of Cordoba, Argentina.

Contribución nutricional del programa Comedores Escolares a la población infantil de diez escuelas municipales de la ciudad de Córdoba, Argentina

Introduction School canteens are one of the most widespread programs in recent decades which may have significant impacts on nutrition, health, growth and development in children.ObjectiveTo assess the nutritional contribution of School Canteens (PCE) program to children from municipal schools of Cordoba.Material and Method Was a descriptive and analytical study. I applied an observation guide and ration weighing measurements of the school canteens food supply and food recall method was used 24 hours a sample of 170 school children.ResultsThe breakfasts/snacks they had a deficit in Calcium, vitamin A and C and iron and excess of simple sugars. The lunches they had a excess of saturated fats and deficit of energy, calcium, iron, fiber and vitamin A. The food consumption of school children was high in discretionary calories, sugars and saturated fats and deficit in fiber, calcium and vitamin A, associated with some sociodemographic characteristics.There had associations between the inadequacy of the target intake of calcium and vitamin found and suboptimal quality and dining in these nutrients (p< 0,05).ConclusionsWe conclude what in this context there are nutritional aspects that are necessary improve.Introduction School canteens are one of the most widespread programs in recent decades which may have significant impacts on nutrition, health, growth and development in children.

Nutritional Epidemiological Tools for Sodium Intake

Dietary sodium is a determinant of blood pressure. Modern diets provide excessive amounts of salt, and in developed and developing countries the intake of processed foods with high salt levels is increasing. In order to establish effective nutrition policy, it is necessary to know the quantity of consumed salt as well as identify the main dietary sources of salt. Different methods are currently in use for estimating dietary sodium intake. The use of 24-hour urinary collection to assess sodium intake is considered the most accurate method but involves considerable burden for participants. The use of the spot urine method has been proposed as an alternative however in not recommended without calibration methodology. Sodium estimates based on dietary surveys include several methods such the 24-hour dietary recall, the food frequency questionnaire, and the diet record, with often under-estimates intake due to under-reporting and difficulties quantifying sodium in concentration discretionary salt and recipes. Food compositions databases and nutritional softwares can be used to assess sodium consumption. More research is necessary to improve nutritional epidemiological tools for sodium intake
