[Diet quality in a population aged over 65 and related socioeconomic factors]. / Calidad de la dieta en mayores de 65 años y factores socioeconómicos relacionados.

INTRODUCTION: The consumption of certain foods and healthy eating habits are related to preventing and suffering from a number of chronic diseases. These foods tend to be included in food pyramids, such as that proposed by the Spanish Society for Community Nutrition. One method of analysing diet quality is the use of indices that assess the frequency of consumption of different food groups. AIM: To analyse diet quality in a Spanish population of persons aged over 65years using the Healthy Eating Index and to determine how sociodemographic factors affect scores on the index. DESIGN: A cross-sectional, descriptive study was conducted on the diet followed at home by Spanish population aged over 65years, using the Healthy Eating Index and taking information from the 2014 European Health Interview Survey in Spain. Multiple linear regression analysis was used to determine the socioeconomic factors associated with diet quality. RESULTS: Of the study population, 89.6% need to make changes in their diet, while only 8.2% follow a healthy diet. Suffering from chronic diseases, overweight and occasional physical exercise were associated with higher scores on the Healthy Eating Index. CONCLUSION: Most of the population aged 65years or over need to make changes in their dietary patterns. Those with potential health risks are more careful about their diet. These findings confirm the need to promote guidelines for healthy eating in the non-clinical population.

[Improvement in adherence to Mediterranean diet in children attending preschool centers]. / Mejoría de la adherencia a la dieta mediterránea en preescolares asistentes al jardín infantil.

Introduction: Background: the Mediterranean diet has been associated with a lower prevalence of obesity and metabolic syndrome, and with healthier lifestyles in adults and children, but data is scarce in younger ages. The Mediterranean-type ecosystem of the central region of Chile as well as its traditional gastronomy would facilitate the adoption of this dietary pattern. Objectives: to assess the adherence to Mediterranean diet in preschoolers and their parents, and to evaluate the impact of a nutrition education intervention and diet implementation. Methods: prospective cohort study. The KidMed index was applied to children older than 18 months, and the Mediterranean Dietary Index in Chile (Chilean-MDI) to their parents, before and after a remote educational intervention. Results: one hundred and thirty-nine families participated, with 95 preschoolers; 56 % were girls, aged 26.2 ± 8.7 months. The basal mean KidMed score was 7.4 ± 1.9 and increased to 7.9 ± 1.9 after the intervention (p = 0.1). The Chilean-MDI score was 6.9 ± 1.8 and 7.1 ± 1.7, respectively (p = 0.09). When separated by categories, there was improvement from low and moderate adherence to optimal adherence in both children and their parents (Chi2, p = 0.009 y p = 0.04). In 58 dyads, there was a positive correlation between the KidMed and the Chilean-MDI index, pre- and post-intervention (Pearson R = 0.3 y 0.34; p = 0.004 y 0.003, respectively). Conclusions: most of these sample of preschoolers and their parents had a moderate adherence to Mediterranean diet, with an improvement after an educational intervention.

Introducción: Introducción: la dieta mediterránea se ha asociado a menor prevalencia de obesidad y síndrome metabólico y a estilos de vida saludable en adultos y escolares, siendo escasa la información en edades menores. La región central de Chile tiene un ecosistema de tipo mediterráneo, lo que, junto con su gastronomía tradicional, facilitaría la adopción de este estilo de alimentación. Objetivos: determinar la adherencia a la dieta mediterránea en preescolares y sus padres y evaluar el impacto de una intervención educativa y su implementación. Métodos: estudio de cohorte prospectiva. Se aplicaron los índices KidMed en niños/as mayores de 18 meses y el Índice Chileno de Dieta Mediterránea (IDM-Chile) en los padres, antes y después de una intervención educativa remota. Resultados: participaron 139 familias, con 95 preescolares, 56 % mujeres, con edad de 26,2 ± 8,7 meses. Inicialmente, el KidMed en los niños fue de 7,4 ± 1,9 puntos y aumentó hasta 7,9 ± 1,9 puntos postintervención (p = 0,1). El IDM-Chile en los padres fue de 6,9 ± 1,8 y 7,1 ± 1,7 puntos, respectivamente (p = 0,09). Al separar por categorías, hubo mejoría desde una adherencia baja o moderada hacia una óptima en los niños y adultos (Chi2, p = 0,009 y p = 0,04). En 58 diadas hubo una correlación positiva entre los índices KidMed e IDM-Chile preintervención y postintervención (R Pearson: 0,3 y 0,34; p = 0,004 y 0,003, respectivamente). Conclusiones: la mayoría de esta muestra de preescolares y sus padres presentaron una adherencia moderada a dieta mediterránea, con una mejoría posterior a la intervención educativa.

[Bioactive components of whole grain and their effect on health]. / Componentes bioactivos del grano integral y su efecto en la salud.

Introduction: Non-communicable diseases represent a global health burden with increasing prevalence. To prevent or improve this type of diseases, dietary strategies based on healthy foods have been suggested. Cereals are the most consumed foods in the world and preventive effects of whole grains on health have been described. The germ and bran of cereals are abundant in bioactive compounds, including phytochemicals, vitamins, minerals and fibers, and these compounds are effective in preventing and improving non-communicable diseases. This review analyzes the content and distribution of the primary components of whole grains (wheat, barley, oats, rice and black wheat) and their fractions, focusing on the mechanisms by which phenolic acids and dietary fiber contribute to reducing the risk of metabolic and cardiovascular diseases and cancer. There is clear evidence of the broad cellular and physiological effects of bioactive compounds in whole grains, supporting the health value of a diet rich in whole grains.

Introducción: Las enfermedades no transmisibles representan una carga sanitaria mundial con una prevalencia cada vez mayor. Para prevenir o mejorar este tipo de enfermedades se han sugerido estrategias dietéticas basadas en alimentos saludables. Los cereales son los alimentos más consumidos en todo el mundo y se han descrito efectos preventivos de los cereales integrales sobre la salud. El germen y el salvado de los cereales son abundantes en compuestos bioactivos, incluidos fitoquímicos, vitaminas, minerales y fibras, y estos compuestos son eficaces para prevenir y mejorar las enfermedades no transmisibles. En esta revisión se analiza el contenido y distribución de los componentes primarios de los cereales integrales (trigo, cebada, avena, arroz y trigo negro) y sus fracciones, centrándose en los mecanismos por los que los ácidos fenólicos y la fibra dietética contribuyen a disminuir el riesgo de padecer enfermedades metabólicas, cardiovasculares y cáncer. Existen pruebas claras de los amplios efectos celulares y fisiológicos de los compuestos bioactivos de los granos enteros, que respaldan el valor saludable de una dieta rica en cereales integrales.

Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention.

We present the Spanish adaptation of the 2021 European Guidelines on Cardiovascular Disease (CVD) prevention in clinical practice. The current guidelines besides the individual approach greatly emphasize on the importance of population level approaches to the prevention of cardiovascular diseases. Systematic global CVD risk assessment is recommended in individuals with any major vascular risk factor. Regarding LDL-Cholesterol, blood pressure, and glycemic control in patients with diabetes mellitus, goals and targets remain as recommended in previous guidelines. However, it is proposed a new, stepwise approach (Step 1 and 2) to treatment intensification as a tool to help physicians and patients pursue these targets in a way that fits patient profile. After Step 1, considering proceeding to the intensified goals of Step 2 is mandatory, and this intensification will be based on 10-year CVD risk, lifetime CVD risk and treatment benefit, comorbidities and patient preferences. The updated SCORE algorithm-SCORE2, SCORE-OP- is recommended in these guidelines, which estimates an individual's 10-year risk of fatal and non-fatal CVD events (myocardial infarction, stroke) in healthy men and women aged 40-89 years. Another new and important recommendation is the use of different categories of risk according different age groups (< 50, 50-69, ≥70 years). Different flow charts of CVD risk and risk factor treatment in apparently healthy persons, in patients with established atherosclerotic CVD, and in diabetic patients are recommended. Patients with chronic kidney disease are considered high risk or very high-risk patients according to the levels of glomerular filtration rate and albumin-to-creatinine ratio. New lifestyle recommendations adapted to the ones published by the Spanish Ministry of Health as well as recommendations focused on the management of lipids, blood pressure, diabetes and chronic renal failure are included.

The Quality Index for Nutrition in Nursing Homes (QUINN). A new tool for evaluating diet quality in long-term care homes.

Introduction: Background: the assessment of diet quality (DQ) is fundamental to the study of disease-diet associations, and it is necesary to implement an easy to-apply tool in nursing homes (NHs). Our objective was to propose and apply a novel diet quality indicator (DQIn) using an a priori approach for NHs. Methods: the QUality Index for Nutrition in Nursing homes (QUINN) was implemented in a public NH located in Valladolid, Spain, during a 5-week period (n = 137 subjects). The choice of the QUINN components was based on a rapid review. The QUINN was based on 15 dietary components - 12 were basic (vegetables, fruits, legumes, olive oil, cereals, dairy, white fish and seafood, white-meat, eggs/positive; other fats, red and processed meat, and sweets/negative), and 3 were supplementary (fruits and vegetables variety, oily-fish, and whole-grains/positive). Each component was classified into 4-categories (0, 1, 2 o 3 points; range: 0-45 points). Results: the QUINN was tested on a menu offered by a NH giving a result of 34 points (good diet). The components with the highest scores were related to the Mediterranean diet (high consumption of legumes, olive oil, white fish and shellfish; low intake of other fats; and a wide variety of fruits and vegetables), together with cereals, white meat, dairy, and eggs. The components that required a major change were red- and processed-meats, sweets, and whole grains. Conclusion: the menu of this Spanish NH showed a good DQ according to the QUINN. The assessment of the DQ in NHs using QUINN will allow the proposal of interventions aimed at improving their diet.

Introducción: Antecedentes: la valoración de la calidad de la dieta es fundamental para el estudio de las asociaciones enfermedad-dieta, y es necesario implantar una herramienta de fácil aplicación en las residencias de ancianos. Nuestro objetivo fue proponer y aplicar un nuevo indicador de calidad de la dieta (diet quality indicator, DQIn) utilizando un enfoque a priori para su utilización en residencias de ancianos. Métodos: el Índice de Calidad Nutricional en Residencias de Ancianos (QUality Index for Nutrition in Nursing homes, QUINN) se aplicó en una residencia pública de Valladolid durante un periodo de 5 semanas (n = 137 sujetos). La elección de los componentes del QUINN se basó en una revisión rápida. En el QUINN se consideraron 15 componentes dietéticos, 12 básicos (verduras, frutas, legumbres, aceite de oliva, cereales, lácteos, pescado blanco y marisco, carnes blancas, huevos/positivos; otras grasas, carnes rojas y procesadas, y dulces/negativos) y 3 adicionales (variedad de frutas y verduras, pescado azul, y cereales integrales/positivos). Cada componente se clasificó en 4 categorías (0, 1, 2 o 3 puntos; rango: 0-45 puntos). Resultados: el QUINN se aplicó en el menú ofertado por una residencia de ancianos dando un resultado de 34 puntos (dieta de buena calidad). Los componentes con mayor puntuación estaban relacionados con la dieta mediterránea (alto consumo de legumbres, aceite de oliva, pescado blanco y marisco, bajo consumo de otras grasas y variedad de frutas y verduras), junto con los cereales, las carnes blancas, los lácteos y los huevos. Los componentes que requerían un cambio importante fueron las carnes rojas y procesadas, los dulces y los cereales integrales. Conclusión: el menú de esta residencia de ancianos situada en España mostró una calidad de la dieta buena según el QUINN. La evaluación de la calidad de la dieta en las residencias de ancianos mediante el QUINN permitirá proponer intervenciones para mejorar la dieta.

The importance of knowing and listening to all those involved in the design and use of nutrition mobile apps. Getting to know the Great GApp.

INTRODUCTION: Almost every country worldwide suffers from one or more types of malnutrition. Mobile technology (mHealth) interventions seem to represent a promising approach to this problem because they help share information about healthy eating patterns, offer motivation for behavioral change, etc. From this perspective we introduce a theoretical model that attempts to explain the gap that currently prevails between the elements involved in the development of nutritional mHealth strategies (which we have called the Great GApp). Evidence tells us that it is necessary to consider all the parts involved to ensure positive outcomes of an mHealth-based nutritional intervention: patients, health care providers, and stakeholders (technological companies). If these elements are not considered in the design of mHealth strategies a Great GApp arises, which may lead to lack of adherence to the proposed change, and decrease the potential for improving the quality of health outcomes.

INTRODUCCIÓN: Casi todos los países del mundo sufren uno o más tipos de malnutrición. Las intervenciones con tecnología móvil (mHealth) parecen representar un enfoque prometedor para este problema porque son útiles para compartir información sobre patrones de alimentación saludable y ofrecer motivación para el cambio de comportamiento, entre otras posibilidades. Desde esta perspectiva, introducimos un modelo teórico que intenta explicar la brecha que prevalece actualmente entre los elementos que participan en el desarrollo de estrategias nutricionales de mHealth (que hemos denominado el Gran GApp). La evidencia nos dice que es necesario tener en cuenta a todos los interesados en el proceso para asegurar los resultados positivos de una intervención de nutrición basada en la mHealth: los pacientes, los proveedores de atención de la salud y las empresas tecnológicas. Si estos elementos no se tienen en cuenta en el diseño de las estrategias de mHealth, surge el Gran GApp, que puede conducir a falta de adherencia al cambio propuesto y disminuir el potencial de mejora de la calidad de los resultados en materia de salud.

Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Cardiovascular Prevention Guidelines. / Comentario del CEIPV a la actualización de las Guías Europeas de Prevención Vascular en la Práctica Clínica.

We present the adaptation for Spain of the updated European Cardiovascular Prevention Guidelines. In this update, greater stress is laid on the population approach, and especially on the promotion of physical activity and healthy diet through dietary, leisure and active transport policies in Spain. To estimate vascular risk, note should be made of the importance of recalibrating the tables used, by adapting them to population shifts in the prevalence of risk factors and incidence of vascular diseases, with particular attention to the role of chronic kidney disease. At an individual level, the key element is personalised support for changes in behaviour, adherence to medication in high-risk individuals and patients with vascular disease, the fostering of physical activity, and cessation of smoking habit. Furthermore, recent clinical trials with PCSK9 inhibitors are reviewed, along with the need to simplify pharmacological treatment of arterial hypertension to improve control and adherence to treatment. In the case of patients with type 2 diabetes mellitus and vascular disease or high vascular disease risk, when lifestyle changes and metformin are inadequate, the use of drugs with proven vascular benefit should be prioritised. Lastly, guidelines on peripheral arterial disease and other specific diseases are included, as is a recommendation against prescribing antiaggregants in primary prevention.

[Nutrition and gastronomy in the community of Cantabria]. / Nutrición y gastronomía en la comunidad de Cantabria.

INTRODUCTION: Introduction: Cantabria is characterized by a large coastal territory and an important livestock tradition, which define its gastronomy. Objectives: population increasingly demands a healthy gastronomy, which promotes a state of health. We will analyze how is the gastronomy, food consumption, and nutritional profile in the community of Cantabria. We will try to relate it to the prevalence of obesity in Cantabria Methods: bibliographic search of scientific articles in PubMed, Google academic databases, and nutrition books. In addition, a search of materials in newspapers of Cantabria and institutions of Cantabria has been developed. Results: in Cantabria a greater amount of fish, oil, dairy products, pastries, pastries, cookies and cereals and fresh fruits is consumed compared to the national average. However, the consumption of soft drinks and soda, fresh vegetables, and bread is lower. With Galicia it occupies the first place in the consumption of fish, food of high nutritional value and high protein content. This consumption profile could contribute to lower energy intake (2038 kcal in 2016) and influence the prevalence of obesity in our community. According to data from 2016, Cantabria with a rate of 17,6% is the fourth community with the lowest prevalence of obesity in Spain. Conclusions: although the prevalence of obesity in our community is in the last places in Spain, the recommendations and nutritional objectives established for the Spanish population have not been reached. Cantabrian gastronomy has to promote a healthy diet, based on a lower contribution of fats and more complex carbohydrates to reach these recommendations.

INTRODUCCIÓN: Introducción: Cantabria se caracteriza por un gran territorio costero y una importante tradición ganadera, que definen su gastronomía. Objetivos: la población demanda cada vez más una gastronomía saludable que promueva un buen estado de salud. Analizaremos cómo es la gastronomía, el consumo alimentario y el perfil nutricional en Cantabria, y trataremos de relacionarlo con la prevalencia de obesidad. Métodos: búsqueda bibliográfica de artículos científicos en las bases de datos PubMed, Google Académico y en tratados de nutrición. Además, se ha realizado una búsqueda de materiales en la prensa local y en las instituciones de Cantabria. Resultados: en Cantabria se consume más pescado, aceite, derivados lácteos, bollería, pastelería, galletas y cereales y frutas frescas que la media nacional. Sin embargo, el consumo de bebidas refrescantes y gaseosas, hortalizas frescas y pan es menor. Junto a Galicia, ocupa el primer puesto en el consumo de pescado, alimento de alto valor nutritivo y elevado contenido proteico. Este perfil de consumo podría contribuir a que la ingesta energética sea menor (2038 kcal en 2016) e influir en la prevalencia de obesidad. Cantabria, en 2016, con una tasa de 17,6%, fue la cuarta comunidad con menor obesidad en España. Conclusiones: aunque la prevalencia de obesidad en nuestra comunidad se encuentra en los últimos puestos de España, no se alcanzan las recomendaciones y objetivos nutricionales establecidos para la población española. La gastronomía cántabra ha de promover una alimentación saludable, basada en un menor aporte de grasas y mayor de hidratos de carbono complejos para cumplir estas recomendaciones.

El moralismo de nuestro plato / The Moralism of our Plate: Reflections on Contemporary Food

Antecedentes: el presente trabajo pretendió abordar, desde un enfoque crítico, los discursos dominantes sobre la alimentación saludable en el campo de la promoción de la salud. Reflexión: las exploraciones sobre el tema permitieron evidenciar las tensiones vinculadas a la normalización de los patrones de consumo como estrategia de moralización dietética que se encuentra instalada en los discursos de la alimentación saludable. Conclusión: estos discursos vienen siendo atravesados por una narrativa normalizadora que ha contribuido a la masificación de recomendaciones sobre consumos alimentarios, independiente de las particularidades socioeconómicas, culturales y simbólicas de los grupos poblacionales. Se identifica una uniformidad de los discursos alimentarios desarraigados de su contexto social y cultural. La dieta saludable se visualiza como una nueva categoría organizadora. Se precisa rediscutir las recomendaciones en torno a la alimentación saludable para que estas no profundicen desigualdades, y recuperar así la alimentación como hecho social y objeto político.

Background: This paper aimed to address, from a critical approach, the dominant discourses on healthy eating in the field of health promotion. Reflection: Explorations on the subject allowed to evidence the tensions linked to the normalization of consumption patterns as a strategy of dietary moralization that is installed in the discourses of healthy eating. Conclusion: These discourses have been influenced by a normalizing narrative that has contributed to the massification of recommendations on food consumption regardless of the socio-economic, cultural, and symbolic particularities of population groups. A uniformity of food discourses is identified, uprooted from their social and cultural context. The healthy diet is visualized as a new organizing category. It is necessary to reconsider recommendations on healthy eating so as not to deepen inequalities, and to recover food as a social fact and political object

Estrés, estrategias de afrontamiento y consumo de alimentos no saludables durante la pandemia de COVID-19 en estudiantes universitarios

Los estudiantes universitarios suelen presentar una dieta poco saludable por estar expuestos, entre otros factores, a situaciones estresantes que se han visto exacerbadas por la pandemia del COVID-19. Para enfrentar el estrés se pueden utilizar diferentes estrategias, sin embargo, se desconoce si los estudiantes universitarios han utilizado dichas estrategias y/o cambiado sus hábitos alimentarios como mecanismo para manejar el estrés durante la pandemia. Este estudio evaluó si el estrés generado durante la pandemia de COVID-19 impactó en los hábitos alimentarios de los estudiantes universitarios y en las estrategias de afrontamiento para enfrentar el estrés. La muestra fue no probabilística y estuvo compuesta por 236 estudiantes universitarios de dos instituciones universitarias chilenas. Se aplicó una encuesta en línea que evaluó consumo de alimentos no saludables, estrés, estrategias de afrontamiento, e información sociodemográfica. Los datos se analizaron mediante regresión binomial negativa. El análisis reveló un aumento en el consumo de alimentos poco saludables, especialmente en estudiantes con altos niveles de estrés. Las estrategias utilizadas se agruparon en 'evitación emocional' y 'mantenerse ocupado'. Se evidenció que los estudiantes más jóvenes preferían las estrategias de evitación emocional y había una fuerte asociación entre las estrategias de "mantenerse ocupado" con un menor consumo de alimentos poco saludables. Estos resultados respaldan el desarrollo de estrategias para el manejo del estrés y de esta forma evitar el consumo excesivo de alimentos poco saludables durante períodos estresantes como la pandemia de COVID-19.

College students often have an unhealthy diet due to exposure to, among other factors, stressful situations that have been exacerbated by the COVID-19 pandemic. Different strategies can be used to cope with stress; however, it is unknown whether university students have used such strategies and/or changed their dietary habits as a mechanism to manage stress during the pandemic. This study assessed whether the stress generated during the COVID-19 pandemic impacted college students' eating habits and coping strategies to deal with stress. The sample was non-probabilistic and was composed of 236 university students from two Chilean university institutions. An online survey was administered that assessed unhealthy food consumption, stress, coping strategies, and sociodemographic information. Data were analyzed using negative binomial regression. The analysis revealed an increase in the consumption of unhealthy foods, especially in students with high levels of stress. The strategies used were grouped into 'emotional avoidance' and 'keeping busy'. It was evident that younger students preferred emotional avoidance strategies and there was a strong association between 'keeping busy' strategies with lower consumption of unhealthy foods. These results support the development of stress management strategies to avoid excessive consumption of unhealthy foods during stressful periods such as the COVID-19 pandemic.

Transición saludable y sostenible en Argentina / Transition healthy and sustainable in Argentina

Inseguridad alimentaria, malnutrición por exceso, patrones alimentarios poco saludables e insostenibles y encarecimiento diferencial de los alimentos más nutritivos, son los factores que intervienen en el complejo panorama alimentario de la población argentina y constituyen sendos desafíos contemporáneos que requieren de cambios en la forma en que se producen, distribuyen, comercializan y consumen los alimentos. Objetivo. Diseñar un modelo de cambios dietarios de transición alimentaria adecuado en términos nutricionales y adaptado a las particularidades del escenario local. Materiales y Métodos. Sobre las principales brechas de excesos dietarios del patrón alimentario argentino se diseñó una matriz de cambios dietarios, considerando tres dimensiones: cantidades, ocasiones y diversificación, transicionales hacia el modelo de referencia (EAT-Lancet) y se determinaron las implicancias económicas del proceso de cambio dietario propuesto. Resultados. Se identificaron 20 estrategias de adaptación dietaria para acortar parcialmente las brechas de carnes (máximo 25%), alimentos feculentos (máximo en torno a ⅕) y sus productos derivados; priorizando aquellos frescos, estacionales y de cercanía. La combinación de cambios dietarios implicaría un ahorro neto de 11% comparado con una canasta saludable. Conclusión. La transición alimentaria hacia modelos más saludables y sostenibles debe considerar cambios flexibles, progresivos y factibles; resguardando los factores socioculturales característicos de la población argentina. Su implementación y mantenimiento requiere de políticas públicas efectivas y voluntad de los diversos actores involucrados, incluyendo a los propios consumidores(AU)

Introduction. NFood insecurity, overnutrition, unhealthy and unsustainable dietary patterns and disproportionate increase in the cost of nutritious foods are the factors that play an important role in the complex nutritional food landscape of the Argentine population and represent contemporary challenges that require changes in the way food is produced, distributed, marketed, and consumed. Objective. Design a model of dietary transition changes that is nutritionally adequate and adapted to the specificities of local scenario. Materials and methods. Regarding the main excesses in the dietary pattern of the Argentinean population, a matrix of dietary changes was designed, considering three dimensions: quantities, occasions and diversification, transitioning towards the reference model (EAT-Lancet). The economic implications of the change process were determined. Results. 20 dietary adaptation strategies were identified to partially reduce the gaps in meat (maximum 25%), starchy foods (maximum around ⅕) and their derivatives products; prioritizing those that are fresh, seasonal and locally sourced products. The combination of dietary changes would imply a net savings of 11% compared to a healthy food basket. Conclusion. The dietary transition towards healthier and more sustainable models must consider flexible, progressive and feasible changes; the sociocultural factors characteristic of the population. Its implementation and maintenance requires effective public policies and the willingness of the various actors involved, including consumers themselves(AU)

Marcadores de alimentação saudável entre adolescentes da rede municipal de ensino de Pelotas, Rio Grande do Sul, 2019: estudo transversal / Healthy eating markers among adolescents from the municipal school system in Pelotas, Rio Grande do Sul, Brazil, 2019: a cross-sectional study / Marcadores de alimentación saludable entre adolescentes del sistema escolar municipal de Pelotas, Rio Grande do Sul, Brasil, 2019: estudio transversal

Objetivo: analisar o consumo de marcadores de alimentação saudável entre adolescentes escolares de Pelotas, Rio Grande do Sul, Brasil, em 2019. Métodos: estudo transversal, realizado nas escolas vinculadas ao Programa Saúde na Escola; o consumo dos cinco marcadores (feijão, leite, frutas, vegetais cozidos, saladas cruas) em até cinco dias antecedentes ao estudo, obtido mediante questionário autoaplicado, foi definido como regular; a associação de variáveis demográficas, socioeconômicas e comportamentais com os desfechos foi analisada por regressão de Poisson. Resultados: entre os 797 entrevistados, 2,8% (IC95% 1,8;4,1) referiram consumo regular; o feijão foi o alimento mais consumido regularmente (48,3%); frutas, vegetais cozidos e saladas cruas foram consumidos regularmente por menos de 30% dos escolares; praticar atividade física, tomar café da manhã e realizar refeições com a família estiveram associados ao consumo regular dos alimentos avaliados. Conclusão: o consumo regular de alimentos saudáveis, encontrado baixo nessa população, associou-se com fatores comportamentais.

Objective: to analyze the consumption of healthy eating markers among adolescent students in Pelotas, Rio Grande do Sul, Brazil, in 2019. Methods: this was a cross-sectional study carried out in schools taking part in the Health at School Program. Consumption of the five markers (beans, milk, fruit, cooked vegetables and raw salads) within five days prior to the study, obtained through a self-administered questionnaire, was defined as regular. Association between demographic, socioeconomic and behavioral variables and the outcomes was analyzed using Poisson regression. Results: among the 797 respondents, 2.8% (95%CI 1.8;4.1) reported regular consumption. Beans were the most regularly consumed food (48.3%); fruit, cooked vegetables and raw salads were consumed regularly by less than 30% of the students. Doing physical activities, having breakfast and having meals with the family were associated with regular consumption of the foods assessed. Conclusion: regular consumption of healthy foods was low in this population, and was associated with behavioral factors.

La práctica de actividad física, el desayuno y las comidas en familia se asociaron con mayor consumo de los alimentos evaluados. Conclusión: el consumo regular de alimentos saludables fue bajo en esta población y se asoció con factores conductuales.

Diseño y validación de una escala para medir la alfabetización alimentaria entre estudiantes universitarios

El objetivo de esta investigación es diseñar y validar una escala para medir la alfabetización alimentaria entre estudiantes universitarios. Su validez se basó en análisis de contenido, de consistencia interna, factorial exploratorio y factorial confirmatorio, aplicados sobre datos correspondientes a estudiantes universitarios de 18 a 25 años, de los programas de administración y nutrición de una universidad mexicana. Los resultados indican que medir la alfabetización alimentaria entre estudiantes universitarios debe considerar cuatro componentes: la selección de insumos y alimentos, el consumo de alimentos con calidad nutricional y en la cantidad apropiada, las actitudes acerca de lo importante que es desarrollar hábitos de alimentación saludables y la percepción del control que las personas tienen sobre su propia alimentación. Una de las principales limitaciones de esta investigación consiste en que la muestra es muy específica, por lo cual, la validación de la escala entre muestras estudiantiles más amplias es una oportunidad para desarrollar futuras investigaciones. Los hallazgos obtenidos son de interés para académicos que participan en el diseño de programas educativos enfocados en el desarrollo de hábitos alimenticios saludables, así como de personas responsables de instrumentar políticas, programas e iniciativas en materia de nutrición, alimentación y salud tendientes a mejorar el bienestar general de la población.

This paper aims to design and validate a scale to measure food literacy among university students. We performed content, internal consistency, exploratory factor, and confirmatory factor analyses, based on data corresponding to management and nutrition university students aged 18-25, at a Mexican university. Our results indicate that measuring food literacy among university students must consider four components: the selection of supplies and foods, the consumption of meals with nutritional quality and in the appropriate quantity, attitudes about the importance of developing healthy eating habits, and the perception of control that consumers have about their diet. One of the main limitations of this study is that the sample is very specific, so the validation of the scale among larger student samples is an opportunity to develop future research. Our findings are of interest to academics who participate in the design of educational programs focused on the development of healthy eating habits, as well as to the designers and developers of policies, programs, and initiatives regarding nutrition, food, and health aimed at improving general well-being.

Urban-rural differences in food consumption and environment and anthropometric parameters of older adults: results from ELSI-Brazil. / Diferenças urbano-rurais relativas ao consumo e ambiente alimentar e aos parâmetros antropométricos de adultos mais velhos: resultados do ELSI-Brasil

Objetivou-se identificar diferenças alimentares e antropométricas entre adultos mais velhos brasileiros (≥ 50 anos) residentes em áreas urbano-rurais. Trata-se de um estudo transversal com dados da segunda onda (9.949 participantes) do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil), de 2019-2021. Foram avaliados: consumo alimentar semanal de fruta/hortaliça, feijão e peixe; autopercepção do consumo de sal; ambiente alimentar (disponibilidade de fruta/hortaliça na vizinhança e produção própria de alimentos); e parâmetros antropométricos objetivos (índice de massa corporal [IMC] e circunferência da cintura [CC]). As análises foram ajustadas por escolaridade. Em comparação com as áreas urbanas, observaram-se nas rurais: menor consumo de fruta/hortaliça em cinco dias da semana ou mais (74,6% vs. 86,4%) e maior consumo adequado de sal (96,8% vs. 92,1%) ­ diferenças observadas para homens e mulheres. A CC elevada foi menor nas áreas rurais (61,9% vs. 68%), sendo significativa somente para homens. Houve menor disponibilidade de fruta/hortaliça na vizinhança (41,2% vs. 88,3%) e maior produção própria de alimentos (38,2% vs. 13,2%) nas áreas rurais. O consumo de fruta/hortaliça em cinco dias da semana ou mais foi menor nas áreas rurais quando houve disponibilidade de fruta/hortaliça na vizinhança e ausência de produção própria de alimentos. Há diversidade alimentar e nutricional entre áreas urbano-rurais. O incentivo ao consumo de fruta/hortaliça nas áreas urbanas deve considerar a disponibilidade de fruta/hortaliça na vizinhança, enquanto nas áreas rurais deve ser em conjunto com a produção do próprio alimento. O consumo adequado de sal e a manutenção da CC nos valores ideais devem ser reforçados nas áreas urbanas

Telessaúde no consumo e comportamento alimentar em adultos: uma revisão rápida de revisões sistemáticas / Telehealth, food consumption, and eating behavior in adults: a rapid review of systematic reviews

Objetivo. Sintetizar as evidências sobre os efeitos de intervenções de telessaúde oferecidas por meio de aplicativos de celular e de mensagens de texto no comportamento de adultos com vistas à alimentação saudável. Métodos. Foi realizada uma revisão rápida por meio de buscas em nove bases eletrônicas da literatura para identificar revisões sistemáticas publicadas em inglês, português e espanhol que avaliassem estratégias de telessaúde comparadas a atendimento presencial para melhoria da alimentação na população adulta (18 a 59 anos). As buscas foram realizadas em novembro de 2020 e atualizadas em abril de 2022. As revisões sistemáticas incluídas foram avaliadas quanto à qualidade metodológica com a ferramenta AMSTAR 2. Resultados. Cinco revisões sistemáticas foram incluídas, sendo uma com avaliação de confiança moderada e as demais com confiança criticamente baixa. Verificou-se uma escassez de estudos comparando o uso de estratégias de telessaúde com o atendimento presencial para a promoção da alimentação saudável em adultos. Os resultados mais consistentes referem-se ao aumento no consumo de frutas e vegetais com o uso de aplicativo ou mensagens de texto, além de melhoria do padrão alimentar de pessoas com diabetes ou intolerância à glicose com o uso de mensagens de texto. Conclusão. A maioria das análises de intervenções utilizando aplicativos de celular ou mensagens de texto mostrou efeitos positivos nos desfechos de alimentação saudável. No entanto, esses achados se referem aos poucos ensaios clínicos com amostras pequenas de participantes incluídos nas revisões sistemáticas da presente revisão rápida, a maioria de baixa qualidade metodológica. Conclui-se que há uma lacuna no conhecimento, sendo importante a realização de estudos metodologicamente mais robustos.

El objetivo fue identificar diferencias alimentarias y antropométricas entre adultos mayores brasileños (≥ 50 años) que viven en áreas urbano-rurales. Se trata de un estudio transversal con datos de la segunda ola (9.949 participantes) del Estudio Longitudinal Brasileño sobre el Envejecimiento (2019-2021). Se evaluaron el consumo semanal de alimentos, como frutas/verduras, frijoles y pescado; autopercepción del consumo de sal; entorno alimentario (disponibilidad de frutas/verduras en el barrio y la producción propia de alimentos); y parámetros antropométricos objetivos (índice de masa corporal [IMC] y circunferencia de la cintura [CC]). Los análisis se ajustaron por escolaridad. Se observó un menor consumo de frutas/verduras en las zonas rurales respecto a las urbanas en ≥ 5 días/semana (74,6% vs. 86,4%), mayor consumo adecuado de sal (96,8% vs. 92,1%), y estas diferencias se observaron para hombres y mujeres. La CC elevada fue menor en las zonas rurales (61,9% vs. 68%), y fue significativa solo para los hombres. Hubo una menor disponibilidad de frutas/verduras en el barrio (41,2% vs. 88,3%) y mayor producción propia de alimentos (38,2% vs. 13,2%) en las zonas rurales. El consumo de frutas/verduras en ≥ 5 días/semana fue menor en las zonas rurales cuando hubo frutas/verduras disponibles en el barrio y ausencia de producción del propio alimento. Existe una diversidad alimentaria y nutricional entre las zonas urbanas y rurales. Fomentar el consumo de frutas/verduras en las zonas urbanas debe tener en cuenta la disponibilidad de frutas/verduras en el barrio, mientras que en las zonas rurales debe tener en cuenta también la producción del propio alimento. Se debe reforzar el consumo adecuado de sal y el mantenimiento de la CC en valores ideales en las zonas urbanas.

This study aimed to identify dietary and anthropometric differences in older Brazilian adults (≥ 50 years old) living in urban-rural areas. This is a cross-sectional study with data from the second wave (9,949 participants) of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) from 2019-2021. Weekly dietary intake of fruit/vegetables, beans, and fish; self-perception of salt consumption; food environment (availability of fruit/vegetables in the neighborhood and self-production of food); and objective anthropometric parameters (body mass index [BMI] and waist circumference [WC]) were evaluated. Analyses were adjusted for schooling level. Compared to urban areas, rural areas show lower consumption of fruit/vegetables five days or more per week (74.6% vs. 86.4%) and greater adequate salt intake (96.8% vs. 92.1%) - differences we observed for men and women. Rural areas showed lower high WC (61.9% vs. 68%), significant only for men. Considering food environment, rural areas had lower fruit and vegetable availability in the neighborhood (41.2% vs. 88.3%) and higher self-production of food (38.2% vs. 13.2%). We observed a lower consumption of fruit/vegetables five days or more per week in rural areas with fruit/vegetable availability in the neighborhood and no self-production of food. Urban and rural areas show food and nutritional diversity. Incentives for fruit or vegetable consumption among residents in urban areas should consider the greater availability of these foods in their neighborhood, whereas, in rural areas, self-production of food should be encouraged. Adequate salt intake and ideal WC maintenance should be reinforced in urban areas.

ABSTRACT Objective. To synthesize the evidence about the effects of telehealth interventions provided through smart-phone apps and text messages on the behavior of adults regarding healthy food consumption. Method. A rapid systematic review of the literature was performed through searches in nine electronic databases to identify systematic reviews published in English, Portuguese, and Spanish that evaluated telehealth strategies compared to face-to-face interventions to improve dietary intake in the adult population (18 to 59 years old). Searches were performed in November 2020 and updated in April 2022. The included systematic reviews were assessed for methodological quality using the AMSTAR 2 tool. Results. Five systematic reviews were included. Methodological quality was moderate in one review and critically low in four. There was a dearth of studies comparing the use of telehealth strategies with face-to-face interventions for the promotion of healthy eating in adults. The most consistent results refer to an increase in the consumption of fruits and vegetables with the use of an app or text messages, in addition to improvement in the dietary habits of people with diabetes or glucose intolerance with the use of text messages. Conclusion. Positive effects were observed on healthy eating outcomes for most interventions using mobile apps or text messages; however, the findings refer to a few clinical trials with small samples that were analyzed in the systematic reviews covered in the present rapid review, most of which had low methodological quality. Thus, the current knowledge gap warrants the performance of further methodologically robust studies.

RESUMEN Objetivo. Sintetizar la evidencia sobre los efectos de las intervenciones de telesalud ofrecidas por medio de aplicaciones de telefonía móvil y mensajes de texto en el comportamiento de la población adulta relacionado con una alimentación saludable. Métodos. Se realizó un examen rápido mediante búsquedas en nueve bases bibliográficas electrónicas para localizar revisiones sistemáticas publicadas en español, inglés y portugués en las que se evaluaran estrategias de telesalud en comparación con atención presencial para mejorar la alimentación de la población adulta (de 18 a 59 años). Las búsquedas se realizaron en noviembre del 2020 y se actualizaron en abril del 2022. La calidad metodológica de las revisiones sistemáticas incluidas se evaluó con la herramienta AMSTAR 2. Resultados. Se incluyeron cinco revisiones sistemáticas, una con un grado de confianza moderado y las otras con un grado de confianza sumamente bajo. Se comprobó una falta de estudios en los que se compararan el uso de estrategias de telesalud con la atención presencial para promover la alimentación saludable de la población adulta. Los resultados más coherentes se refieren al aumento del consumo de frutas y verduras con el uso de aplicaciones móviles o de mensajes de texto, así como a la mejora del patrón alimentario de las personas con diabetes o con intolerancia a la glucosa con el uso de mensajes de texto. Conclusión. La mayoría de los análisis de las intervenciones en las que se emplearon aplicaciones de telefonía móvil o mensajes de texto mostraron efectos positivos en los resultados relativos a una alimentación saludable. Sin embargo, estos hallazgos se refieren a unos pocos ensayos clínicos con pequeñas muestras de participantes incluidos en las revisiones sistemáticas del presente examen rápido, en su mayoría de baja calidad metodológica. En conclusión, existe una laguna en los conocimientos y es importante realizar estudios con una metodología más sólida.
