Prevention of Children Obesity: A Nutrition Education Intervention Model on Dietary Habits in Basic Schools in Chile  [PDF]
Fernando Vio, Gabriela Fretes, Edith Montenegro, Carmen Gloria González, Judith Salinas
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.613128
Abstract: The objective of this study is to describe the process and results of a three-year project designed to create a nutrition education intervention model that promotes healthy dietary habits among teachers, students and their families. The methodology consisted in surveys, focus groups and Delphi method to assess teachers’, students’ and parents’ dietary habits, followed by an intervention for parents, and a participative nutritional education intervention with information and communication technologies applied to teachers, with the purpose to transfer nutritional knowledge and habits to school children and their families. Qualitative results were measured in all the phases of the project with positive results, and quantitative results demonstrated significant changes in food knowledge and healthy dietary habits in parents, teachers and students, compared with the control groups, without changes in students’ nutritional status during the short period of the intervention. With the results, an integral school nutrition education model in healthy eating was developed with children, parents, teachers and support for school management. This model should be applied in the educational sector to address the problem of unhealthy diet and childhood obesity that affects Chile and the world.

Food and Nutrition Sciences (FNS) , 2016, DOI: 10.4236/fns.2016.710088
Abstract: Objective: Use a school-based food garden as an instrument to improve healthy dietary consumption, habits, and practices among children from the third to fifth grade in public schools in Chile. Design: Quasi-experimental, six-month intervention with an evaluation of dietary consumption, habits, and practices and use of the school-based food garden among the 3rd to 5th grade students. Setting: Two municipal schools in a low-middle income district in Santiago de Chile; one with a school garden intervention and a control school without a garden. Subjects: 155 third to fifth grade children, 63 in the intervention school and 92 in the control school (average age 10 years old, 58% boys). Results: In the intervened school, there was a significant improvement in the children’s dietary habits, such as peeling and slicing fruit (p < 0.05), making sandwiches (p < 0.05), and increased motivation to cook (p < 0.05). Fruit purchases at the school rose from 4% to 37% (p < 0.05) by the end of the intervention. Interest in growing vegetables or fruits at home increased from 48% to 70% (p < 0.05). The school children at the intervention school significantly increased their knowledge about 16 of 21 garden crops (p < 0.05), expanding the spectrum of the vegetables they can consume. There were no significant changes in the control school. Conclusions: The school-based food garden was effective in achieving change in dietary habits and practices among the third to fifth grade children. The project should be carried out for a longer period of time, so that the changes will be reflected in the students’ food consumption and nutritional status.
Aproximación a una caracterización molecular de Fasciola hepatica por la técnica RAPDs - PCR MOLECULAR CHARACTERIZATION APPROACH OF Fasciola hepatica BY TECHNIQUE RAPDs-PCR
Parasitología latinoamericana , 2003,
Abstract: El presente estudio muestra la caracterización molecular de Fasciola hepatica obtenidas de bovino, equino y ovino, utilizando la técnica de Amplificación al Azar de Fragmentos de ADN Polimórficos (RAPDs-PCR). Para este fin, se lograron estandarizar las condiciones óptimas de amplificación y programa de termociclación de RAPDs-PCR para F. hepatica, así como marcadores genéticos de identificación poli-mórfica características para cada especie. La metodología utilizada consideró comparar los patrones genéticos interespecie e intraespecie, a partir de muestras de F. hepatica. Los resultados obtenidos muestran marcadores genéticos al azar, que evidencian variabilidad genética de F. hepatica intra e interespecie (polimorfismo), y cuyos fragmentos de amplificación fluctuaron entre los 135 y 741 pares de bases (pb) The present study show the molecular characterization of Fasciola hepatica taken from cows, horses and sheeps, using the Random Amplified Polymorphic ADN Fragments (RAPDs-PCR) technique. The standardization of the optimal conditions of amplification and thermocyclation for F. hepatica by RAPDs-PCR were made, as the genetic markers for polymorphic identification of the parasites collected from different animals specie.The methodology used compared the genetic pattern between species and inside each specie. The results shows random genetic markers, given genetic variations of F. hepatica between species and inside each specie (polymorphism), and the amplifications fragments were between 135 and 741 pair of bases (bp)

Abstract: eosinophilic esophagitis in adults (ee) is a disease of unknown cause, characterized by symptoms such as reflux and dysphagia that traditionally do not respond to antacid treatment. it affects mostly young men with a strong personal or familial history of a topy asthma and allergies. we repot three male patients aged 10, 14 and 15years, all with symptoms of dysphagia, two of them with chest pain caused by spasm of the esophagus, with heterogeneous endoscopic findings which included from leucoplakia to stenosis that needed endoscopic dilatation. all of them had abnormal findings in immunity studies (prick test or ige levels). they received treatment based on diet measures, acid suppression and leukotriene inhibitors, with satisfactory clinical, endoscopic and histological response. ee should be suspected in children and adults with esophageal symptoms and personal or family history of allergy and asthma.
Sedación, Seguridad y Utilidad de la Endoscopia Digestiva Alta en Pediatría Sedation, Safety and Usefulness of Upper Gastrointestinal Endoscopy in Pediatrics
Revista chilena de pediatría , 2010,
Abstract: Introducción: El estudio endoscópico alto es un procedimiento diagnóstico y terapéutico considerado de rutina, pero su realización en pediatría se encuentra limitada dada la necesidad de sedación y monitoreo adecuados. Objetivos: Evaluar la sedación, indicación y percepción de los padres del examen. Materiales y Métodos: Estudio prospectivo de 190 ni os sometidos a endoscopia digestiva alta. Se obtuvieron datos bio-demográficos, tipo de sedación y resultados del examen. Resultados: La edad fue 8,5 + 4,2 a os, la mayoría referidos por pediatra (60%). La principal indicación del estudio fue el dolor abdominal recurrente (29,8%). Los pacientes fueron clasificados de acuerdo al ASA (93% ASA I y II). En la mayoría se requirió de 2 ó más drogas para lograr sedación óptima. La calidad del procedimiento fue satisfactoria en más del 90%. Un 75,5% presentaron amnesia completa y un 42,7% molestias leves posterior al procedimiento. Entre los hallazgos destacaron signos de esofagitis en el 13,9%, observándose un 61% de los exámenes normales. Al analizar los pacientes por peso (mayores y menores de 14 kg), se encontraron diferencias en edad (p < 0,00001), ASA (p = 0,001), indicación de endoscopia (p = 0,001) y evaluación de la sedación por enfermera (p = 0,038). Conclusión: Procedimientos endoscópicos en ni os pueden realizarse de manera segura en forma ambulatoria mediante sedación moderada. Una adecuada monitorización y conocimiento de técnicas de reanimación son básicos al momento de realizar dichos procedimientos. Introduction: Upper gastrointestinal studies are routine diagnostic and therapeutic procedures. In pediatrics, however, they are limited by the need for sedation and monitoring. Objectives: Po evaluate sedation, indication, and parent perception of these exams. Patients and Methods: Aprospective study of 190 pediatric upper gastrointestinal endoscopies was undertaken. Demographic data, as well as information regarding the exam was obtained. Results: Patients' average age was 8.5 ± 4.2, mostly referred by pediatricians (60%) Main reason for referral was recurrent abdominal pain (29.8%). Patients were classified according to ASA criteria (93% ASA I and II). Most patients required two or more medications for optimal sedation, with satisfactory procedure in over 90%. Over 75.5% had complete amnesia, 42.7% presented minor discomfort after the procedure. Findings of these procedures included 61% of normal exams, 13.9% esophagitis. More findings were there result of analyses according to children's weight (over or under 14 kg), age, ASA, reason for referral, n

Abstract: El objetivo de este estudio fue hacer un análisis comparativo del conocimiento y consumo alimentario entre los escolares, sus padres y profesores, que sirva como línea de base para un modelo de intervención educativa en alimentación y nutrición en el ámbito escolar. Para ello se realizaron encuestas a ni os y ni as de prekinder, kínder, primero y segundo a o básico, sus padres y profesores acerca del conocimiento y consumo de alimentos saludables y no saludables. Se encontró un excelente conocimiento en los ni os de lo que era una alimentación saludable, con un adecuado consumo de ellos. En los padres, en cambio, a pesar de tener conocimientos adecuados, su consumo era muy poco saludable, al igual que en los profesores. Respecto a la distribución de las comidas en el día, un 98% de los padres se aló que toman desayuno; un 96% que almuerzan y un 77% que toman té u once. En la noche cenan tan sólo un 55%, siendo este hábito significativamente mayor en los padres de prekinder y kínder que en los de 1° y 2° a o básico. Los padres de prebásica no dan dinero Conducta de los padres en a sus hijos para que compren golosinas en la escuela; sin embargo un 33% de los padres de primero y segundo básico si lo hacen, lo que demuestra que existe una mayor preocupación por la alimentación saludable en los ni os más peque os, que se pierde cuando ingresan a la educación básica. Todo lo anterior demuestra que es imperativo contar con programas de educación alimentaria y nutricional que considere la situación actual de conocimientos y hábitos de consumo de los ni os, sus padres y profesores, para que los incluya en forma conjunta en la educación alimentaria nutricional. The objective of this study was to conduct a comparative analysis about food knowledge and food consumption in preschool and school-age children, their parents and teachers to establish a baseline for a nutrition education intervention model in schools. For that purpose, surveys were administered about healthy and non-healthy food knowledge and food consumption. Results showed an excellent healthy food knowledge and food consumption in children. In parents, despite a good knowledge about healthy food, consumption was unhealthy. The same situation was found in teachers. Distribution of food during the day showed that 98% of parents had breakfast; 96% had lunch, and 77% had an afternoon snack instead of dinner (just 55% had dinner). The number of pre-school age parents who ate dinner was significantly higher than school-age parents. Pre-school age parents did not give money to their children to buy snacks at

Retos : Nuevas Perspectivas de Educación Física, Deporte y Recreación , 2010,
Abstract: The introduction of the European Higher Education Area in a new culture of quality in Higher Education, makes us ask about the aspects that give quality to it. Among the quality factors in Higher Education we can find: University guidance and analysis of the graduate′s incorporation into the labour world. In this article we present the research we did in conducted at the six classes of graduates of Teaching in Physical Education from the University of Seville (N = 292). From the data we obteined, we can observe that 95% of the surveyed population does not ask for work or professional guidance during their degree and 63% of the surveyed population find their first job connected with the world of sport and physical activity, while 37% of this population has a work connected with other topics. Thus, we can conclude that most graduates of Teaching in Physical Education do not receive guidance for their incorporation into the labour world. This is why no everygraduate can get a job connected with the world of sport and physical activity.
