Background: A massive open online course (MOOC) is an online course aimed at unlimited participation and open access via the Web. Aim: To assess the MOOC experience for teaching nutrition, healthy food consumption, physical activity and health promotion to prevent obesity. Material and Methods: Two MOOC courses, (one with two versions), are described with the registration and evaluation instruments such as surveys carried out at the beginning and at the end of the courses. Effective participants in the three versions were 17.456, 11.121 in MOOC1, 2.351 in MOOC1 second version and 3.984 in MOOC2. Their median age was 31 years, 82% were women, 60% were professionals and 12% were foreigners. Results: In the final evaluation of the three courses, 85% to 99% qualified as “very good” or “good” all the surveyed topics. Thirty five percent of participants reported having lack of time, 11% reported problems with internet connectivity and 3.9%, personal or work problems. Conclusions: This is the first experience with MOOC in health and nutrition to prevent obesity in Chile. Considering the good results and positive evaluation of these courses, we estimate that they are an important tool to prevent obesity and chronic diseases in Chile, Latin America and other regions of the world.

ABSTRACT This article describes the nutritional status, food consumption, dietary behavior and culinary skills of third to fifth grade public school students from the La Reina neighborhood, Santiago de Chile, in order to propose healthy eating interventions. This is a cross-sectional, descriptive study in 617 children (349 males and 268 females) from third (n= 193), fourth (n= 202) and fifth grade (n= 222). Obesity prevalence was 30.3%, greater than the 24.2% reported by National Board of Scholarships and Grants in first grade in 2015. Most of the children reported liking cooking (66.2%), but just 20.0% cooked mixed or seasoned vegetables, made sandwiches, or peeled or cut 4 or 5 days per week. All children (100%) ate a late snack in the afternoon, but only 60.9% ate dinner at night. A second breakfast was eaten by 20.7% of the children and a second lunch by 35.7%. Almost all children (97%) brought money or a snack from home: 78.4% brought candies, 60.0% fruit, 50.0% dairy products and 48.4% soft drinks or juices with sugar, and 45.0% money (500 to 1000 Chilean pesos). It is necessary to educate children in healthy eating habits, with participation of parents and support from the Ministry of Education to prevent children obesity.

Introduction: FINDRISK questionnaire evaluates the probability of developing mellitus (DM) within 10 years. Objective: To determine the probability of developing DM within 10 years in healthcare personnel, considering lifestyle and family burden using the FINDRISK questionnaire. Material and methods: Cross-sectional descriptive prospective study performed in 100 individuals, healthcare personnel of the Hospital de Clínicas from September 1 to October 3, 2015. Results: The sample population was mostly women (77%), predominantly young (73%), 19% has parents and/or brothers/sisters with DM. Thirty two percent had normal weigh, 27% was overweight, 24% had GI obesity and 17% GII obesity. Only 30.4% made physical activity. Half eats fruits and vegetables every day. Only 6% had history of hyperglycemia and 43% presented a very high risk by abdominal circumference. Only 16% used regularly drugs for arterial hypertension. Applying the FINDRISK questionnaire, the global mean was 14.4 ± 4.4 (range 7 - 24) being similar in both genders (p = 0.6). In the risk assessment, almost half (47%) of the employees presented high risk followed by slightly high risk (31%), moderate risk (11%) and very high risk (11%). In the bivariate analysis using 15 of FINDRISK as a cut-off point, it was found that 38% of the employees had high risk levels. Conclusion: More than a third of the healthcare personnel had high risk level of developing DM in their evolution if preventive measures are not taken to avoid it. Measures should be taken to reduce the appearance of new cases or delay the beginning of DM.

Introducción: el cuestionario FINDRISK permite evaluar la probabilidad de desarrollar diabetes mellitus (DM) a 10 años. Objetivo: determinar la probabilidad de desarrollar DM a 10 años en el personal de salud, teniendo en cuenta el estilo de vida y su carga familiar utilizando el cuestionario FINDRISK. Materiales y métodos: estudio prospectivo, descriptivo, de corte trasversal, realizado en 100 individuos, personal de blanco del Hospital de Clínicas, desde el 1 de septiembre de 2015 a 31 de octubre de 2015. Resultados: la muestra fue mayoritariamente del sexo femenino (77%), predominantemente joven (73%), 19% tienen padres y/o hermanos con DM. Tenían peso normal 32%, sobrepeso 27%, obesidad GI 24% y obesidad GII 17%. Solo realizan actividad física 30,4%. La mitad consumen frutas y verduras todos los días. Solo 6% presentaban antecedentes de hiperglicemia. El 43% presenta riesgo muy elevado por circunferencia abdominal. Solo 16% consumen regularmente medicamentos para la hipertensión arterial. Aplicando el cuestionario de FINDRISK la media global fue de 14,4 ± 4,4 (rango 7 -24) siendo similar en ambos sexos (p 0,6). En la valoración del riesgo, presentaban FINDRISK riesgo alto casi la mitad (47%) de los funcionarios, seguido de 31% riesgo ligeramente elevado, riesgo moderado 11% y riesgo muy alto 11%. En el análisis bivariado, utilizando como punto de corte de 15 del FINDRISK, encontramos que 38% de los funcionarios tienen nivel de riesgo alto. Conclusión: más de un tercio del personal de blanco tiene un alto nivel de riesgo de desarrollar DM en su evolución si no se toman medidas preventivas para evitarlo. Se deberían tomar medidas para disminuir la aparición de casos nuevos o retardar el inicio de la DM.

Objective: To know nutrition, education and gastronomic expert opinion to get consensus about education methodologies in healthy food topics for third to fifth school-age children, their parents and teachers, with the Delphi method. Methods: A questionnaire was developed with the results of surveys and focus groups in children, parents and teachers made previously. The questionnaire was mailed to 51 experts in nutrition, education and gastronomic in a first round. The results were analyzed and forwarded in a second round with the subjects without consensus, with 38 experts answering the questionnaire. Results: Food habits can be modified at school with cooking workshops with chefs or monitors in an experiential learning and with school gardens. Parents and teachers should have cooking skills to educate children in healthy food. Children should do a rational management of their money at school buying healthy food. For this purpose it is necessary to change the food offered by the kiosk or remove the kiosk if is non healthy. Teachers should be trained in self-care and healthy lifestyles and they should educate children with education materials, cooking workshops with recipes, taking advantage of breakfast and lunch time for education activities. Parents should participate in workshops learning about healthy food choices and how to prepare healthy menus. Children should learn very simple culinary skills, preparing and tasting healthy food. Conclusions: These results are critical to design educational materials on healthy eating plans to change current eating habits.

Objetivo: mediante la técnica de consenso Delphi, conocer la opinión de un grupo de expertos en nutrición, educación y gastronomía para buscar consenso sobre metodologías educativas en alimentación saludable en alumnos de tercero a quinto año básico, sus familias y profesores. Métodos: con los resultados de encuestas y grupos focales realizados previamente a niños, padres y profesores, se elaboró un cuestionario que fue enviado a 51 expertos en nutrición, educación y gastronomía en una primera ronda. Los resultados fueron analizados y reenviados en una segunda ronda con las preguntas no consensuadas, obteniendo 38 respuestas. Resultados: hubo consenso en que se pueden cambiar hábitos en escuelas mediante talleres de cocina con chefs o monitores, educación activo-participativa y huertos escolares. Padres y profesores deben tener habilidades culinarias saludables para educar a los niños. Estos deben hacer uso racional del dinero en la escuela. Para ello es necesario cambiar la oferta del kiosko hacia alimentos saludables, o suprimirlo si no es saludable. Los profesores deben capacitarse con talleres de autocuidado y vida sana para educar en alimentación saludable a los niños en horarios de clase con material educativo, talleres de cocina con recetas y aprovechar horarios de desayuno y almuerzo para actividades educativas. Los padres deben participar en talleres para escoger alimentos saludables en lugares de venta y preparar menús saludables. Los niños deben aprender habilidades culinarias simples, preparando y degustando alimentos saludables. Conclusiones: estos resultados son fundamentales para diseñar materiales educativos en alimentación saludable que cambien los malos hábitos alimentarios actuales.

Background: Unhealthy lifestyles and overweight are common among blue collar workers. Aim: To evaluate a nutrition education intervention in construction workers to prevent chronic diseases. Material and Methods: One hundred forty two participants were randomly assigned to an experimental group (n = 69) and or a control group (n = 73). The experimental group received nutrition education consisting in individual lifestyle counseling, group workshop, group counseling in healthy lifestyles, and environmental intervention. At baseline and after one year of intervention, clinical evaluations consisting in laboratory determinations, anthropometry and nutritional assessment evaluation were carried out. Results: The experimental group experienced a significant decrease in waist circumference, total cholesterol, triglycerides, and an increase in HDL cholesterol. A significant reduction in total calorie intake, especially at the evening snack was observed during week-days. The same reduction in total calories occurred at dinner during the week-end. A significant increase was observed in the consumption of fruits, vegetables and fish. In the control group there was a significant increase in weight, waist circumference, body mass index, glucose and insulin, without changes in total calorie intake or healthy food consumption. High soft drink consumption did not change in both groups. Conclusions: In construction workers, integral nutrition intervention at the individual, group and environmental level had an impact in nutritional and biochemical indicators.

The objective of this study was to describe food consumption, dietary behaviour and culinary habits in third to fifth grade students and their families through surveys and focus groups to implement nutrition education interventions in healthy eating habits at schools. Surveys in parents and children demonstrated that healthy food consumption was under the Chilean Dietary Guidelines recommendations. Consumption of fruits, vegetables and dairy food in parents was less than in children, but non-healthy food consumption was also less in parents. In dietary behavior 22% of children consumed breakfast at home and also at school, and 33% consumed double lunch. Snack was carried from home in 60% of children, but 72% carried money to buy non-healthy snacks at school. Parents said that they had norms related to dietary behavior at home, but 60% watched TV during dinner and 96% had afternoon tea and just 42.2% had dinner. Regarding culinary habits, students had the skills to prepare simple food but did not have the skills to prepare a dish. The mothers said they had the culinary skills but they cook simple food like pasta, rice and potatoes. Focus groups confirmed survey findings, identifying three profiles in mothers and separating eating behaviour during the weekdays and weekend. Its notorious that mothers consuming a healthy diet were those who had more health problems. Barriers to healthy eating were lack of time and money. Surveys and focus groups showed a good access by parents and children to Information and Communication Technologies. In conclusion, it is urgent to design nutrition education programs to create healthy eating habits considering the current situation in food consumption, dietary behaviour and culinary habits in students and their parents.

El objetivo de este estudio fue describir el consumo, los hábitos alimentarios y las habilidades culinarias en alumnos de tercero a quinto año básico y de su familia por medio de encuestas y grupos focales para realizar intervenciones educativas en alimentación saludable en el ámbito escolar. Para ello se realizaron encuestas a alumnos y padres, que se complementaron con grupos focales. Según las encuestas, el consumo de alimentos saludables en alumnos y padres estuvo por debajo de lo recomendado en las Guías Alimentarias. El consumo de frutas, verduras y lácteos en los padres fue menor que en los hijos, pero consumieron menos alimentos no saludables. En hábitos, 22% de los niños tomaba doble desayuno y 33% doble almuerzo. Un 60% llevaba colación de la casa, pero 72% llevaba dinero destinado a compra de alimentos poco saludables. Los padres decían tener normas, pero un 60% veía televisión cuando comía, 96% tomaba once y 42,2% cenaba. En habilidades culinarias, los alumnos podían preparar alimentos simples, pero no un plato de comida. Las madres decían tener habilidades culinarias, pero cocinaban en forma ocasional y comida básica como papas, arroz y fideos. Los grupos focales confirmaron lo anterior, identificando tres perfiles de madres y diferenciando lo que comen en la semana con los fines de semana. Destaca el perfil de madres que se alimenta saludable, que eran las que han tenido un problema de salud. Las barreras para alimentarse bien son el alto costo y la falta de tiempo. Las encuestas y grupos focales mostraron un buen acceso de padres e hijos a las Tecnologías de la Información y Comunicación. Lo anterior demuestra el imperativo de contar con programas de educación nutricional prácticos para crear hábitos de alimentación saludable que consideren la situación actual de consumo, hábitos alimentarios y habilidades culinarias de los alumnos y sus padres.

Introduction: An instrument to measure food knowledge, food consumption, cooking skills, food habits and food expenses at school is necessary to assess changes in food practices. Objective: To validate an instrument to measure changes in food knowledge, food consumption, cooking skills, food habits and food expenses in Chilean school children 8 - 11 years from third to fifth grade. Methods: A validation of a questionnaire with 42 questions was conducted in two stages: the first to assess temporal stability, concordance and internal consistency in 45 children. The second one to apply the survey, modified with the results of the first stage, in 90 children assessing internal consistency. Results: The first survey with 42 questions showed a reasonable temporal stability, concordance and internal consistency for cooking skills, habits and food expenditure at school. Internal consistency was good for food consumption, but not so good for food knowledge. In the final validation with 90 children, there was good consistency for food consumption but bad for food knowledge. Besides, children with cooking skills ate more healthy food and those who expended more money at school, consumed less healthy food. Conclusions: Food knowledge questions were eliminated from the instrument, which was elaborated with 28 questions about food consumption, cooking skills, food habits and food expenses at school. This instrument is useful to assess changes in food and nutrition education interventions in 8 -11 years children, in particular to measure cooking skills and food expenses at school.

Introducción: Para medir cambios en prácticas alimentarias, se requieren instrumentos que midan conocimiento, consumo, habilidades culinarias, hábitos y gastos en alimentos en las escuelas. Objetivo: Validar un instrumento que permita medir cambios en conocimiento, consumo, habilidades culinarias, hábitos y gastos en niños de 8 a 11 años, de tercero a quinto básico, en escuelas públicas de Chile. Métodos: Se realizó un estudio de validación de un cuestionario de 42 preguntas de conocimiento, consumo, habilidades culinarias, hábitos y gastos en la escuela. Se realizó en dos etapas: la primera en 45 niños para evaluar la estabilidad temporal, concordancia y consistencia interna. La segunda fue aplicar el instrumento modificado con los resultados de la primera etapa en 90 niños para medir consistencia interna. Resultados: El cuestionario aplicado en los 45 niños mostró estabilidad temporal, concordancia y consistencia interna aceptables para habilidades culinarias, hábitos y gastos en la escuela. La consistencia fue buena para frecuencia de consumo, pero mala en conocimiento. En la validación final con 90 niños, se confirmó la buena consistencia para frecuencia de consumo y mala para conocimiento. Se observó que aquellos niños con habilidades culinarias, consumen más alimentos saludables y los que gastan más dinero en la escuela, consumen menos alimentos saludables. Conclusiones: Al instrumento se le quitaron las preguntas de conocimiento, quedando con 28 preguntas de consumo, habilidades culinarias, hábitos y gasto en alimentos en las escuelas. Este instrumento es útil para medir cambios en intervenciones educativas en alimentación y nutrición en niños de 8 a 11 años.

The objective of this paper is to analyze the theoretical and methodological basis for a nutrition education program in healthy food for the school community. Conceptual basis and the experience of a nutrition education intervention for parents and teachers are described. An innovative and participative methodology with the utilization of Information and Communication Technologies (ICT) are presented. In this methodology parents and teachers transfer healthy food concepts to children at home and in the school. A proposal for an integral education model for schools is presented.

El objetivo de este artículo es presentar las bases teóricas y metodológicas para un programa educativo de alimentación saludable en la comunidad escolar. Se describen los fundamentos conceptuales y la experiencia de una intervención educativa experimental con padres y profesores en escuelas básicas. Se presenta una metodología innovadora, de carácter participativo y práctico con uso de Tecnologías de la Información y Comunicación (TIC) en el cual los profesores transfieren lo aprendido a los niños en la escuela y a los padres en el hogar. Se realiza una propuesta para un modelo educativo integral para los establecimientos educacionales.

El objetivo del estudio fue evaluar el efecto de un programa de intervención con metodologías educativas innovadoras en alimentación y nutrición en profesores y alumnos de prebásica y básica, para lograr una mejoría en sus conocimientos, ingesta alimentaria y estado nutricional. Se realizó un estudio cuasi experimental en que se evaluó conocimiento, consumo alimentario y estado nutricional al inicio y término de la intervención educativa. La muestra quedó constituida por 25 profesores y 465 alumnos de Los Andes y 352 estudiantes controles de San Felipe. La intervención consistió en 9 sesiones educativas para los profesores en temas de alimentación saludable durante 5 meses, con transferencia de conocimientos a sus alumnos. Hubo una mejoría significativa en conocimiento y una disminución en el consumo de alimentos poco saludables en los alumnos de los profesores que recibieron la capacitación, con respecto al grupo control, sin cambios significativos en el estado nutricional de ambos grupos. En conclusión, la intervención en los profesores mejoró el conocimiento e ingesta de alimentos saludables en sus alumnos, sin modificar el estado nutricional por su corta duración. Si esta estrategia se mantiene en el tiempo y se incorpora al currículo escolar, puede lograr resultados en el largo plazo, incorporando a los padres en esta tarea.

The objective of the study was to assess the impact of a nutrition education program for teachers to improve food knowledge, food consumption and the nutritional status of their pre basic and basic students. A quasi-experimental study was carried out, with a pre-post evaluation of food knowledge, food consumption and nutritional status. The sample was 25 teachers and 465 students in Los Andes, with 352 students as control group in San Felipe. The nutrition intervention consisted in 9 interactive workshops for teachers during 5 months, transferring the information to the students. In the experimental group there was a significant improvement in food knowledge and a decrease in non-healthy food consumption in students, compared with the control group, without changes in nutritional status. In conclusion, the intervention in teachers improved food knowledge and healthy food consumption in students. As a consequence of the short period of intervention, the nutritional status did not change. If these strategies are maintained over time and incorporated to the school curricula could achieve more significant results, in particular if parents are incorporated in school nutrition education programs.

Background: The less affluent and educated members of the society tend to be less prone to healthy lifestyles. Aim: To describe feeding habits, nutrition, quality of life and working conditions of construction workers comparing two recent surveys, namely the 2009 Chilean National Health Survey (NHS) and the 2010 Work, Employment and Health Survey (WEH). Material and Methods: One hundred ninety male workers aged 43 ± 13 years were surveyed about feeding habits during working days and weekends, smoking and usual physical activity. Weight, height and blood pressure were also measured. Results: In 2010, 82% of workers were overweight or obese compared with 67% rates in the NHS of 2009. The rate of sedentariness was 86% compared with 84% in the NHS of 2009 and 93% in the WEH 2010. Forty one percent smoked and those aged less than 25 years consumed more calories than the other age groups. There was a high intake of carbonated beverages, bread, salted and red meats and a low consumption of fruits, vegetables, legumes and fish. Seventy seven percent had a meal at midafternoon and only 25% ate supper. Lunch had a fixed schedule, was considered good and usually was prepared by a family member. The level of satisfaction with work, family life and life in general was high. The satisfaction with health and physical condition was lower. Conclusions: The unhealthy lifestyles of these construction workers should alert health authorities.
