RESUMEN
INTRODUCTION: Breastfeeding (BF) is the healthiest form of nutrition for babies and is recommended exclusively (EBF) for at least the first six months of life. The carbon footprint of formula feeding (FF) has been studied, but that of BF is unknown. AIM: To identify the environmental impact of three types of infant feeding taking into account the accessories needed and the diet of postpartum women in the baby's first month of life. METHODS: This is a multicentre, cross-sectional study conducted in the Barcelona North Metropolitan Area (Catalonia, Spain). The participating sites are primary care settings that will recruit 408 postpartum women (4-6 weeks) as per inclusion/exclusion criteria. The data will be collected through a GREEN MOTHER Survey that includes 4 dimensions: 1) socio-demographic and clinical data; 2) data on the newborn and accessories used in infant feeding; 3) general data on the mother's diet (food consumption habits), and 4) recording of 24 h of the mother's diet. The data analysis will be performed to check the prevalence of infant feeding types at birth and month 1, as well as a comparative analysis of three types of infant feeding on environmental impact (climate change; water consumption, and scarcity). ETHICS: This project was approved by the Research Ethics Committee of the Jordi Gol i Gurina University Institute Foundation for Primary Health Care Research (IDIAP) under code 22/101-P dated 22/02/2023. DISCUSSION: A second phase of the GREEN MOTHER study is planned, which will consist of an educational intervention to promote breastfeeding, nutrition and sustainability. This intervention will be based on the results obtained in Phase I. We expect that the project results - through the publication and dissemination of scientific papers and reports among relevant stakeholders (association of community midwives, healthcare and primary care attention professionals and the public) - will increase public awareness of breastfeeding and its impact on sustainability. TRIAL REGISTRATION: Both phases of the GREEN MOTHER study protocol were registered in ClinicalTrials.gov, NCT05729581.

INTRODUCTION: Prep-4-RT is a co-designed stepped-care multimodal prehabilitation program for people scheduled to receive radiotherapy for head and neck cancer (HNC). Prehabilitation, which occurs between diagnosis and treatment commencement, aims to improve a patient's health to reduce the incidence and severity of current and future impairments. HNC treatment can be distressing and has detrimental impacts on function and quality of life. HNC patients have increased social vulnerabilities including higher rates of socio-economic disadvantage and engagement in lifestyle habits which increase cancer risk. High levels of physical and psychological impacts of HNC treatment and increased social vulnerabilities of this population warrant investigation of optimal pathways of care, such as prehabilitation. This paper describes a research protocol to evaluate the feasibility of Prep-4-RT, which was designed to prepare HNC patients for the physical and psychological impacts of radiotherapy. METHODS AND ANALYSIS: At least sixty adult HNC patients, scheduled to receive radiotherapy (with or without chemotherapy), will be recruited over a five-month period. All participants will receive access to Prep-4-RT self-management resources. Participants identified through screening as high-risk will also be offered individualised interventions with relevant allied health professionals prior to the commencement of radiotherapy (psychologists, dietitians, speech pathologists and physiotherapists). Participants will complete evaluation surveys assessing their experiences with Prep-4-RT resources and interventions. Clinicians will also complete program evaluation surveys. Primary feasibility outcomes include adoption (uptake and intention to try) and fidelity (adherence to the specialist prehabilitation pathway). Secondary feasibility outcomes include acceptability (patient and clinician) of and satisfaction (patient) with Prep-4-RT as well as operational costs. Feasibility outcome data will be analysed using exact binomial and one-sample t tests, as appropriate. ETHICS AND DISSEMINATION: Ethics approval has been obtained at the Peter MacCallum Cancer Centre in Melbourne, Australia. Results will be presented at national conferences and published in peer-reviewed journal(s) so that it can be accessed by clinicians involved in the care of HNC patients receiving radiotherapy. If the model of care is found to be feasible and acceptable, the transferability and scalability to other cancer centres, or for other cancer types, may be investigated.

RESUMEN
BACKGROUND: While numerous studies have reported associations between low dietary potassium intake and adverse clinical outcomes, methods to estimate potassium intake, mainly self-reported dietary measures and urinary potassium excretion, entail certain limitations. Self-reported measures are subject to underreporting and overreporting. Urinary potassium excretion is affected by multiple factors including renal function. Revealing the degree of bias inherent in these measures would help accurately assess potassium intake and its association with disease risk. We aim to summarize evidence on the strength of the associations between potassium intake estimated from 24-h urinary potassium excretion and potassium intake estimated from self-reported dietary measures or objective quantification methods in populations with different kidney function levels and age groups. We also aim to identify factors that affect the association strength. METHODS: We will search for potentially eligible studies that examined associations between self-reported potassium intake, 24-h urinary potassium excretion, and objectively quantified potassium intake, using MEDLINE (PubMed), Embase, Web of Science, and Scopus. Studies on children, adolescents, adults, and the elderly are eligible. Studies of patients on dialysis will be excluded. Collective study results, including a meta-analysis, will be synthesized if an adequate number of studies examining similar dietary potassium intake estimation methods are found. Analyses will be performed separately according to age groups and renal function. For the meta-analysis, fixed-effects or random-effect models will be employed depending on the degree of study heterogeneity to combine across studies the correlation coefficient, ratio, or standardized mean difference for potassium intake, comparing dietary potassium intake based on self-reported or objectively quantified methods and intake based on 24-h urinary potassium excretion. The degree of heterogeneity among included studies will be examined by calculating I2 statistics. To investigate sources of study heterogeneity, random-effects meta-regression analyses will be performed. DISCUSSION: Revealing the strength of the association between dietary and urinary measures in populations with different levels of kidney function and age groups will enhance researchers' and clinicians' ability to interpret studies that utilize these measures and help establish a more solid evidence base for the role of potassium intake in changing chronic disease risk. Identifying factors that modify the associations between these measures may aid in developing predictive models to estimate actual potassium intake.

BACKGROUND: Empathy is fundamental to the provision of efficacious patient-centered health care. Currently, there is no comprehensive synthesis of peer-reviewed empirical research related to empathy in the nutrition and dietetics profession. Understanding empathy in the context of nutrition and dietetics care may lead to improved teaching practices that support nutrition and dietetics students and practitioners to provide high-quality, empathic, patient-centered care. OBJECTIVE: This scoping review aimed to understand the approaches through which empathy is conceptualized, measured, and taught in the field of nutrition and dietetics. METHODS: Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Reviews Statement and Checklist, a scoping review process was undertaken. Five databases were searched in February 2023: Cumulative Index to Nursing and Allied Health, Embase, Medline, PsycInfo, and Scopus, with no date limits. Eligible studies were English language-based, peer-reviewed, empirical research exploring or measuring empathy as an outcome in primary data stratified to nutrition and dietetics. Extracted qualitative data were synthesized and analyzed thematically with an inductive, interpretivist approach applied to conceptualize the interrelationship between empathy and dietetic practice. Quantitative data were extracted and summarized in a table. RESULTS: Twenty-six studies were included in the scoping review. Analysis identified 2 overarching themes underpinning the current literature on empathy in nutrition and dietetics that described empathy as a key skill in the application of patient-centered care, which was supported by approaches to lifelong cultivation of empathy in the nutrition and dietetics profession. A range of tools has measured empathy in nutrition and dietetics students and practitioners with no clear consensus in findings across studies. CONCLUSIONS: This review identified the extent and nature of empathy within nutrition and dietetics, from both practitioner and patient perspectives, and the vast array of approaches used to teach and quantify empathy in students and practitioners. Insights from this review inform the need for future studies. The results of this review suggest that future research include exploring implications of empathic dietetics care on patient outcomes and identification of best practice, evidence-based curricula and strategies to support sustainable cultivation and maintenance of empathic care across the career span of nutrition and dietetics practitioners.
RESUMEN
Eating behaviour that does not centralise weight, otherwise known as weight-neutral, is associated with improved physical and psychological health, and greater health promoting behaviours. However, consolidated evidence is lacking. This study aimed to systematically evaluate 'health-centric' eating behaviour reflective of weight-neutral approaches, and their relationship with health (physical and mental) and health promoting behaviours. A systematic search was performed, identifying observational studies with adult populations, ≥1 physical/mental health outcome(s), and ≥1 validated measure(s) of health-centric eating behaviour. Study design, sample characteristics and outcomes were extracted and characterised into four domains. Our search identified 8281 records, with 86 studies, 75 unique datasets, and 78 unique exposures including 94,710 individuals. Eating behaviours included intuitive eating (n = 48), mindful eating (n = 19), and eating competence (n = 11). There were 298 outcomes identified for body composition, size, and physical health (n = 116), mental health and wellbeing (n = 123), health promoting behaviours (n = 51) and other eating behaviour (n = 8). Higher levels of intuitive eating, mindful eating and eating competence were significantly related to a lower BMI, better diet quality and greater physical activity. Higher intuitive and mindful eating were significantly related to lower levels of disordered eating, and depressive symptoms, and greater body image, self-compassion, and mindfulness. Greater eating competence and intuitive eating were significantly related to higher fruit and vegetable intake, and greater eating competence to higher fibre intake and better sleep quality. Our results demonstrate that 'health-centric' eating behaviours are related to a range of favourable health outcomes and engagement in health promoting behaviours. These findings help to enhance our understanding of eating behaviours that do not centre around body weight, providing support for health-centric eating behaviour in healthcare. Future research should focus on intervention studies and more diverse population groups.

AIMS: This scoping review aimed to identify and map the available information on the nutrition care process in older adults with delirium to analyse and summarise key concepts, and gaps, including the barriers and enablers to providing nutrition care for this group. DESIGN: Scoping review. METHODS: This review was conducted in accordance with the JBI methodology for scoping reviews. Published and grey sources in English were considered. DATA SOURCES: Databases searched were CINAHL, Medline, Embase, JBI Evidence-based Practice, Scopus, ProQuest and Google. The initial search was conducted from October 2021 to March 2022 and repeated in October 2023. RESULTS: The database search identified 1561 articles, 186 underwent full-text review and 17 articles were included. The grey literature search identified eight articles. Malnutrition and delirium were identified as mutually reinforcing, and nutrition strategies were included as part of multicomponent interventions for delirium management. There was no mention of barriers or enablers to nutrition care and minimal descriptive or empirical data available to guide nutrition care processes in this group. CONCLUSION: This scoping review revealed a need for further research into nutrition care processes in older patients with delirium, in particular the barriers and enablers, to inform appropriate management strategies in this vulnerable group. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Providing nutrition care for older patients with delirium is important and further practical guidance could help patients, healthcare staff and families. IMPACT: This scoping review yielded instructive data suggesting that delirium is an important risk factor for malnutrition and vice versa, which leads to poor patient and health service outcomes. REPORTING METHOD: This scoping review adhered to relevant EQUATOR guidelines and used the Preferred Reporting Items For Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). PATIENT OF PUBLIC CONTRIBUTION: No patient or public contribution.
RESUMEN
La prestación de servicios para la atención integral de la salud requiere la participación de diversos profesionales con competencias específicas para brindar la mejor atención posible a la población. La inclusión del nutricionista en los diferentes niveles del sistema de salud es crucial para garantizar una atención integral en las diversas etapas de la vida. Una distribución inequitativa de nutricionistas en los niveles de atención puede conducir a una fragmentación de la atención y la pérdida de oportunidades para abordar los problemas relacionados con la alimentación y nutrición. Por ello, se desarrolló un estudio con el objetivo de describir la distribución de nutricionistas en los establecimientos de salud según el nivel de atención, y evaluar el cumplimiento de las recomendaciones de recursos humanos establecidas por la norma técnica de las UPSS de Nutrición y Dietética. Se desarrolló un estudio descriptivo y transversal, mediante el análisis de fuentes secundarias. Se utilizaron los datos de recursos humanos por IPRESS de SUSALUD, del año 2022. Se consideró la Norma técnica de UPSS de Nutrición y Dietética para evaluar el cumplimiento de las recomendaciones de recursos humanos. Entre los principales resultados, se identificó que el 7.93% de los establecimientos de salud del primer nivel de atención tienen al menos un nutricionista. En el segundo nivel de atención, el 96.35% de los establecimientos de salud no cumplen con las recomendaciones de recursos humanos de la norma técnica, y ningún establecimiento del tercer nivel de atención cumplió esta recomendación. La distribución de nutricionistas en los diversos niveles de atención del sistema de salud peruano es desigual. Es necesario mejorar la planificación de recursos humanos en el sistema de salud peruano para garantizar una atención integral de la salud a la población.
The provision of services for comprehensive healthcare requires the involvement of various professionals with specific competencies to provide the best possible care to the population. The inclusion of nutritionists at different levels of the healthcare system is crucial to ensure comprehensive care at various stages of life. An unequal distribution of nutritionists across healthcare levels can lead to fragmented care and missed opportunities to address nutrition-related issues. Therefore, a study was conducted with the aim of describing the distribution of nutritionists in healthcare facilities according to the level of care and evaluating compliance with the human resources recommendations established by the technical standard of Nutrition and Dietetics UPSS. A descriptive and cross-sectional study was conducted using the analysis of secondary sources. Human resources data from SUSALUD for the year 2022 were used. The Technical Standard of UPSS of Nutrition and Dietetics was considered to assess compliance with human resources recommendations. Among the main findings, it was identified that 7.93% of first-level healthcare facilities have at least one nutritionist. In the second level of care, 96.35% of healthcare facilities do not comply with the human resources recommendations of the technical standard, and no third-level healthcare facility met this recommendation. The distribution of nutritionists across various levels of care in the Peruvian healthcare system is unequal. It is necessary to improve human resources planning in the Peruvian healthcare system to ensure comprehensive healthcare for the population..
RESUMEN
Antecedentes: La evaluación de los perfiles de egreso es uno de los aspectos centrales en la acreditación de carreras en Chile, por cuanto su formulación y aplicación en los procesos formativos influyen en sus niveles de pertinencia y calidad. Objetivo: Evidenciar las fortalezas y debilidades del diseño y aplicación de los perfiles de egreso de las carreras de Nutrición y Dietética en Chile, a partir de los resultados de sus procesos de acreditación. Materiales y métodos: Estudio transversal, descriptivo, cualitativo. Se identificaron, en las resoluciones de acreditación entre los años 2004 y 2016, las fortalezas y debilidades de los perfiles de egreso y las contradicciones entre lo declarado y lo ejecutado por los programas. Las carreras se ordenaron en dos grupos según el tiempo de acreditación: i) de dos a cuatro años y ii) de 5 o más años. Usando el software Atlas.ti 7.0 se determinaron los patrones y diferencias conceptuales en los juicios evaluativos de los perfiles de egreso. Resultados: Existe una alta variabilidad entre carreras en los contenidos y aplicación de los perfiles de egreso. Ella se asocia a las capacidades instaladas en las instituciones y a los tiempos de acreditación de la carrera. Existen carreras con déficit en el cumplimiento de competencias, conocimientos y habilidades. Conclusiones: Los contenidos y aplicación de perfiles de egreso son muy heterogéneos y su aplicación se asocia al tiempo de acreditación de la carrera. Es necesario limitar la alta dependencia a la demanda y estimular mayores compromisos institucionales.
Background: Assessment of the graduate profiles is one of the key aspects of program accreditation in Chile, therefore, their development and application in training processes have an impact on their relevance and quality. Objective: To demonstrate the strengths and weaknesses of the design and application of graduate profiles of Nutrition and Dietetics degree programs in Chile, on the basis of the outcomes of their accreditation processes. Materials and methods: Cross-sectional, descriptive, qualitative study. Strengths and weaknesses of graduate profiles, and inconsistencies between what was stated and what was actually implemented in the programs were identified in the accreditation resolutions issued between 2004 and 2016. Degree programs were classified in two groups, according to accreditation years: i) two to four years, and ii) five or more years The Atlas.ti 7.0 software was used to determine patterns and conceptual differences in the evaluative judgement of graduate profiles. Results: There was a high variability in the content and application of graduate profiles between degree programs. This was associated with the institutions' installed capacities and with accreditation years awarded to the program. Some programs were not compliant with the required competencies, knowledge and skills. Conclusions: The content and application of graduate profiles are highly heterogeneous, and its application is associated to accreditation years of the program. It is necessary to limit high dependency on demand to encourage stronger institutional commitments.
RESUMEN
RESUMEN Introducción. El objetivo de este estudio es establecer patrones positivos y negativos de los resultados de los procesos de acreditación de las carreras. Asimismo, identificar desde una perspectiva cualitativa, variables relevantes y relaciones entre los criterios usados en su evaluación. Materiales y métodos. El estudio es transversal, descriptivo y cualitativo. Se analizaron veinte resoluciones de acreditación de las carreras de Nutrición y Dietética en Chile, emitidas entre los años 2004 y 2016 por la Comisión Nacional de Acreditación mediante el software ATLAS ti. Se consideraron las tres dimensiones; Propósitos e Institucionalidad; Condiciones de Operación y Resultados; y Capacidad de Autorregulación para establecer una matriz de relaciones con la identificación de patrones positivos y negativos entre criterios. Resultados. Se evidencian fuertes diferencias entre las carreras. Las relaciones positivas y negativas entre los códigos de los criterios perfil de egreso y plan de estudio indican que solo algunas de ellas proveen una formación adecuada. Del mismo modo, las relaciones entre la calificación del cuerpo docente y la investigación revelan casos de docentes sin niveles suficientes. Otros aspectos deficitarios son el nivel con que ingresan los estudiantes y el uso efectivo de diagnósticos y autoevaluaciones. Conclusiones. El estudio provee información relevante para la toma de decisiones y procesos de retroalimentación orientados al urgente mejoramiento y aseguramiento de la calidad de carreras, en particular de sus planes de estudio, calificación de docentes y efectividad de los procesos de aseguramiento de la calidad, dada la creciente importancia de estos profesionales en la salud pública.
ABSTRACT Introduction. The objective of this study is to establish positive and negative patterns based on the results of accreditation processes of degree programs. Similarly, its aim is to identify, from a qualitative perspective, relevant variables and relationships among the criteria used in their evaluation. Materials and methods. This is a cross-sectional, descriptive and qualitative study. Twenty accreditation resolutions of Chilean Nutrition and Dietetics degree programs were analyzed using the software ATLAS ti. Resolutions were issued between 2004 and 2016 by the National Accreditation Commission. Three dimensions were considered in order to establish a matrix of relationships associated with the identification of positive and negative patterns among criteria: Purpose and Institutionalism; Operating Conditions and Results; and Self-Regulatory Ability. Results. Major differences were found among the degree programs. Positive and negative relationships between criteria codes, graduate profile and curriculum, indicate that only some degree programs provide an appropriate training. In the same way, the relationship between the teaching staff qualification and research work revealed cases of teachers who were not sufficiently qualified. Other weak aspects were the level of knowledge that students have when they enter university and the effective use of diagnostics and self-assessment tests. Conclusions. This study provides relevant information for decision making and feedback processes oriented at the urgent improvement and quality assurance of degree programs, particularly of curricula, teaching staff qualifications, and effectiveness of the quality assurance processes, given the increasing importance of nutrition professionals in the public health area.
RESUMEN
RESUMEN El propósito de este artículo es analizar la evolución de las carreras y programas de Nutrición y Dietética en Chile. Se verifica un incremento sostenido de la oferta formativa, particularmente en los últimos veinte años, asociado a procesos de mercantilización de la Educación Superior. El aseguramiento de la calidad ha operado a través de la acreditación voluntaria y sus resultados son congruentes con el contexto nacional. La creciente importancia de la alimentación y nutrición en la salud pública del país exige formular cambios en la formación en Nutrición y Dietética, para lo cual se plantean diversas recomendaciones para lograr mayores niveles de pertinencia y el mejoramiento continuo de la calidad.
ABSTRACT The purpose of this article is to analyze the evolution of Nutrition and Dietetics degree programs and majors in Chile. This research demonstrated a sustained increase in the number of training programs, particularly during the last twenty years, due to the process of commodification of higher education. Quality assurance has been implemented by voluntary accreditation, which has shown results consistent with the national context. The growing importance given to food and nutrition in the national public health scenario requires changes in Nutrition and Dietetics academic programs. To this end, different recommendations are made in order to achieve improved relevance standards and continuous quality improvement.

Considering the increase in higher education institutions that offer the Nutrition program and the paradigm shift in the healthcare area oriented to a bio psychosocial approach, which can be understood as a holistic look at the principal actors in the educational process and whose development is not only technical and professional, but also educational. The aim of this article was to describe the composition of the cultural and social capital of the students enrolled in the Nutrition and Dietetics program at the University del Mar of Talca. This was a quantitative, non-experimental, cross-sectional and descriptive study; a survey with close ended question was applied to 45 students. The descriptive statistics results were analyzed using SPSS v.20 and indicated the composition of cultural and social capital of the universe of this study, allowing characterization of each individual whose program training implies a search for social mobility, security, notions of self-expression, and valoric composition proper to modernity.
Considerando el incremento de instituciones de educación superior que ofertan la Carrera de Nutrición, y el cambio paradigmático en el área de salud orientado a un enfoque biopsicosocial, el que podemos entender como una mirada holística hacia los actores en este proceso educativo, cuyo desarrollo no es sólo técnico y profesional, sino también formativo; el presente artículo pretende describir la composición del capital cultural y social de estudiantes de la carrera de Nutrición y Dietética de la Universidad del Mar de Talca. Estudio cuantitativo, no experimental, transversal y descriptivo, con muestra de 45 estudiantes a quienes se les aplicó un cuestionario con preguntas cerradas. Los resultados analizados con estadística descriptiva y utilizando el programa SPSS v.20, indican que la composición del capital cultural y social de los sujetos, permite caracterizar a un estudiante cuya formación disciplinar implica una búsqueda de movilidad social, seguridad, generando nociones de autoexpresión, y una composición valórica muy propia de la modernidad.

No cenário mundial, a emergência do campo da Nutrição foi um fenômeno característico do início do século XX. No Brasil, a emergência da Nutrição localizou-se na área das Ciências da Saúde (ou Ciências da Vida), caracterizando-se, à primeira vista, como uma ciência de natureza biológica. Este artigo tem por objetivo analisar a trajetória do processo de produção do conhecimento científico que garantiu especificidade ao campo da Nutrição no Brasil, da emergência aos dias atuais. Os pressupostos teóricos que norteiam o artigo são: o conceito de campo científico, desenvolvido por Pierre Bourdieu e os conceitos de paradigma e comunidade científica, introduzidos por Thomas Samuel Kuhn. A análise histórica evidencia que desde o seu nascimento, além da natureza biológica, a Nutrição brasileira assumiu dimensões sociais e ambientais, caracterizando-se como um campo de conhecimento multidisciplinar, constituído a partir da integração de Ciências Biológicas, Ciências Sociais e Ciências dos Alimentos e Nutrição. Nas últimas décadas, com o intenso desenvolvimento da comunicação e informática, da genética e das teorias sobre a sustentabilidade ecológica do planeta Terra, importantes mudanças paradigmáticas têm ocorrido no campo da Nutrição. Portanto, pode-se afirmar que a Nutrição estaria vivenciando a era pós-genômica, constituindo-se uma ciência multidisciplinar, caracterizada pela integração das dimensões biológica, social e ambiental.
In the world scenario, the emergence of nutrition science was a phenomenon characteristic of the early Twentieth Century. In Brazil, its emergence occurred in the health sciences area (or life sciences) and was characterized, at first, as a science of biological nature. This article aims to analyze the trajectory of the process of producing scientific knowledge which ensured specificity to the field of nutrition in Brazil, from its emergence to the present. The theoretical assumptions that guide the article are: the concept of scientific field, developed by Pierre Bourdieu, and the concepts of paradigm and scientific community, introduced by Thomas Samuel Kuhn. Historical analysis shows that, from birth and in addition to its biological nature, Brazilian nutrition assumed social and environmental dimensions, being characterized as a multidisciplinary field of knowledge formed from the integration of the biological sciences, social sciences and food and nutrition sciences. In the last decades, with the intensive development of communication and information technology, genetics and sustainability theories, major paradigmatic changes have occurred in the field of nutrition. Therefore, one can say that nutrition is experiencing a post-genomic era and becoming a multidisciplinary science, characterized by the integration of the biological, social and environmental dimensions.
