Barreras para una alimentación saludable: un análisis cualitativo de las semánticas emergentes en las comunidades escolares de Ciudad Sur

La literatura ha hecho hincapié en la centralidad que cumplen los entornos alimentarios en las elecciones alimentarias y en el estado nutricional de la población. Objetivo: identificar las percepciones de padres, madres y apoderados, profesionales de establecimientos educacionales, funcionarios municipales, y feriantes pertenecientes a la zona sur de Santiago de Chile, respecto a las barreras y limitaciones de la puesta en práctica de una alimentación saludable en el ambiente alimentario escolar. Método: se realizaron seis grupos focales agrupando a 50 actores claves vinculados a los establecimientos educacionales de Ciudad Sur utilizando una muestra no probabilística. Se aplicó un análisis de contenido mediante la técnica de codificación temática buscando relevar los universos semánticos emergentes. Resultados: se identificaron nueve barreras, o semánticas, que caracterizan limitantes a la realización de la alimentación saludable en los entornos escolares desde la perspectiva de los participantes: la familia, kioscos escolares, la salida de los establecimientos escolares, gusto, determinantes socioeconómicos, política pública, falta de conocimiento, publicidad y disponibilidad de productos sin sellos. Conclusiones: las limitaciones asociadas al ambiente alimentario doméstico tienen una representación significativamente alta (47,9%) y contienen un carácter de responsabilización individual en su enunciación. Esta cultura explicativa es opuesta a la evidencia científica y académica respecto al funcionamiento de la conducta alimentaria, y a la centralidad de los ambientes alimentarios respecto a la facilitación u obstaculización del consumo de alimentos saludables o adecuados.

Literature has emphasized on food environments centrality in food choices and nutritional status. Objective: identify social perceptions of fathers, mothers and guardians, professionals from educational establishments, municipal officials, and stallholders belonging to the southern area of Santiago de Chile, regarding limitations of healthy diet implementation on school environments. Method: six focus groups were carried out grouping 50 key actors linked to educational establishments using a non-probabilistic sample. A content analysis was applied through thematic coding technique seeking to reveal emerging semantic universes. Results: Nine barriers, or semantics, were identified characterizing limitations to healthy eating habits in school environments: family, school kiosks, leaving school establishments, taste, socioeconomic determinants, public policy, lack of knowledge, publicity, and availability of products without seals. Conclusions: limitations associated with domestic food environment have a significantly high representation (47,9%) and contain an individualized responsibility feature. This explanatory culture is opposed to scientific and academic evidence regarding the functioning of eating behavior, and the centrality of food environments facilitating or hindering healthy food consumption.

Validation of the Brazilian version of the Short Inventory of Grazing (SIG)

Abstract Objective Grazing is a disturbed eating pattern that has been associated with eating disorders and obesity. One of the new measures to investigate this eating behavior is the Short Inventory of Grazing (SIG), a two-item questionnaire that assesses grazing in general and grazing associated with the feeling of loss of control over eating (LOC grazing). However, the psychometric properties of the SIG have not been assessed in the Brazilian population. The present study aimed to cross-culturally adapt and validate a Brazilian version of the SIG. Methods The SIG was adapted to the Brazilian context following international guidelines. Then, 90 undergraduate students completed an online survey including questions from the SIG, the Binge Eating Scale (BES), the Patient Health Questionnaire-9 (PHQ9), the Generalized Anxiety Disorder-7 (GAD7), and a question related to self-reported health status. The internal consistency, test-retest reliability, and convergent validity of the questionnaire were assessed. Results The prevalence rates of at least one weekly episode of grazing in general and LOC grazing were 71.1 and 54.5%, respectively. The internal consistence of the SIG was acceptable (0.81). In addition, SIG scores on both items were positively and significantly associated with BES, GAD7, and PHQ9 scores, and with poorer self-rated health. However, SIG test and retest scores differed significantly. Conclusion Overall, the Brazilian version of the SIG demonstrated adequate psychometric properties. The instrument had adequate internal consistency, with both items exhibiting good convergent validity with related measures.

Validation and calibration of the Food Consumption Frequency Questionnaire for pregnant women

ABSTRACT BACKGROUND: Few food frequency questionnaires (FFQ) have been validated for pregnant women, particularly those in small- and medium-sized cities in different regions of Brazil. OBJECTIVES: To validate and calibrate a semiquantitative FFQ for pregnant women. DESIGN AND SETTING: The study was validated with a sample of 50 pregnant women (≥ 18 years) enrolled in Brazilian prenatal services. METHODS: An FFQ and a 24-hour recall were used to evaluate dietary intake. Dietary variables were tested for normality and log-converted when asymmetrical. Pearson's Correlation Coefficient was used to validate the questionnaire. Linear regression was applied to extract calibration factors. All variables underlying the consumption analysis were adjusted for energy. RESULTS: The mean age of the pregnant women was 26 years ± 6.2 years; 58% were in their first trimester, and 30% were identified as overweight/obese. The Pearson correlation analysis results indicated that the FFQ overestimated energy and nutrient intake, whose coefficients ranged from −0.15 (monounsaturated fat) to 0.50 (carbohydrate). Adjusting for energy reduced the mean values of intake coefficients, which now ranged from −0.33 (sodium) to 0.96 (folate). The calibration analysis results indicated variation in the coefficients from −0.23 (sodium) to 1.00 (folate). Calibration produced satisfactory coefficients for the FFQ compared with the reference standard for energy, macronutrients, monounsaturated fat, cholesterol, vitamins B12/C, folate, sodium, iron, and calcium. CONCLUSIONS: After validating and calibrating tests, we observed that the FFQ was adequately accurate for assessing the food consumption of the pregnant women in this study.

Evolution of adolescents' dietary patterns in Northeast Brazil from 2008 to 2018

ABSTRACT OBJECTIVE To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil. METHODS Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008-2009 and 2017-2018. A total of 3,095 adolescents were evaluated in 2008-2009 and 3,015 in 2017-2018. Food consumption was assessed using two dietary records in 2008-2009 and two 24-hour recalls in 2017-2018, applied on non-consecutive days. Based on these data, principal components factor analysis (PCFA) was performed, followed by orthogonal rotation of the varimax type, to derive dietary patterns, stratified by sex. The results were described as means or percentage frequencies, with their respective 95% confidence intervals. RESULTS Three main dietary patterns were identified among adolescents from the northeast region of Brazil. Among boys, in 2008-2009, the patterns were called snacks, traditional Brazilian, and coffee; and in 2017-2018, traditional Brazilian, snacks, and mixed, in this order of representativeness of the group's eating habits. Among female adolescents, in 2008-2009, the patterns were snacks, traditional Brazilian, and coffee; and in 2017-2018, traditional Brazilian, snacks, and processed meats. CONCLUSION The dietary patterns identified in 2008-2009 and 2017-2018 were similar in both genders; however, the snacks pattern, which explained most of the data variability in 2008-2009, was replaced by the traditional Brazilian.

Dificuldades alimentares em pré-escolares de uma escola de educação infantil / Feeding difficulties in preschool children at an early childhood education school

Dificuldade alimentar é todo problema que afeta negativamente o processo dos pais ou cuidadores de suprirem alimento ou nutrientes à criança. O objetivo deste trabalho foi investigar as dificuldades alimentares em pré-escolares de uma escola municipal de educação infantil de Uruguaiana/RS. O estudo foi aprovado pelo Comitê de Ética em Pesquisa e realizado entre outubro e novembro de 2022. Foram convidadas a participar da pesquisa todos os pais ou responsáveis das crianças (n=70) que frequentavam a escola, na faixa etária de 4-5 anos. Todos receberam o Termo de Consentimento Livre e Esclarecido, bem como o questionário de pesquisa. O instrumento utilizado foi a Escala Brasileira de Alimentação Infantil (EBAI), que possui 14 perguntas referentes à alimentação das crianças. Foi realizada estatística descritiva, em termos de frequência e realizada análise de variância (ANOVA) para comparações entre os sexos (p<0,05). Foram obtidas 31 respostas dos pais relativas à alimentação das crianças. Os dados revelaram que 9,68% (n=3) possuíam algum grau de dificuldade alimentar, sendo 3,33% (n=1) com grau severo e 6,45% (n=2) com grau moderado. As demais crianças (n=28) também apresentaram comportamentos relacionados às dificuldades alimentares, porém, sem pontuação suficiente para serem classificadas com dificuldade alimentar. Os comportamentos mais frequentemente descritos foram: o responsável usar distrações ou ir atrás da criança para que ela coma, tempo de a alimentação em torno de 31-60min ou mais, criança que nauseia, cospe ou vomita com algum tipo de alimento e a influência negativa da alimentação nas relações familiares. Desta forma, observou-se um baixo percentual de dificuldades alimentares na população estudada, de acordo com a literatura estudada.

Feeding difficulties are any problem that negatively affects the process of parents or caregivers providing food or nutrients to the child. The objective of this work was to investigate eating difficulties in preschool children at a municipal early childhood education school in Uruguaiana/RS. The study was approved by the Research Ethics Committee and carried out between October and November 2022. All parents or guardians of children (n=70) who attended school, aged 4-5 years, were invited to participate in the research. Everyone received the Free and Informed Consent Form, as well as the research questionnaire. The instrument used was the Brazilian Infant Feeding Scale (EBAI), which has 14 questions regarding children's nutrition. Descriptive statistics were performed in terms of frequency and analysis of variance (ANOVA) was performed for comparisons between sexes (p<0.05). 31 responses were obtained from parents regarding children's nutrition. The data revealed that 9.68% (n=3) had some degree of feeding difficulty, 3.33% (n=1) with a severe degree and 6.45% (n=2) with a moderate degree. The remaining children (n=28) also presented behaviors related to feeding difficulties, however, without enough scores to be classified as having feeding difficulties. The most frequently described behaviors were: the caregiver using distractions or going after the child to make them eat, feeding time around 31-60 minutes or more, child who nauseates, spits or vomits with some type of food and the negative influence of food in family relationships. Thus, a low percentage of feeding difficulties was observed in the studied population, in accordance with the literature studied.

Terapia oromotora: Estudio de un modelo educativo para cuidadores primarios / Oral-motor therapy: Study of a distance learning educational model for primary caregivers / Terapia motora oral: estudo de um modelo de ensino à distância para cuidadores primários

Los trastornos alimentarios y de deglución afectan considerablemente la calidad de vida de niños y niñas con discapacidades neuromotoras. La pandemia de COVID-19 agravó estos desafíos al limitar el acceso a la atención en salud. Este estudio evaluó un modelo educativo de aprendizaje a distancia en terapia oral-motora, dirigido a personas cuidadoras de niños y niñas con discapacidades neuromotoras en Mérida, México. Participaron incialmente treinta personas cuidadoras de niños y niñas entre 2 y 12 años de edad con trastornos alimentarios y de deglución, quienes recibían atención en siete instituciones. 23 participantes completaron el programa. Se usó un diseño cuasiexperimental de prueba pre y post. El programa incluyó sesiones teóricas y prácticas. Los resultados mostraron mejoras significativas en el conocimiento teórico y en las competencias prácticas, con niveles de competencia superiores al 80%. Aun así, se reconocen limitaciones del estudio como el tamaño de la muestra y la ausencia de un grupo de control. Abordar estas limitaciones en investigaciones futuras fortalecerá la evidencia sobre la efectividad de este enfoque innovador centrado en la persona cuidadora, crucial para gestionar trastornos alimentarios y de deglución de manera efectiva y mejorar la calidad de vida de niños y niñas con discapacidades neuromotoras.

Eating and swallowing disorders are prevalent among children with neuromotor disabilities, significantly impacting their overall quality of life. The COVID-19 pandemic exacerbated the challenges by restricting access to health care, underscoring the necessity for innovative solutions with caregiver involvement. This study investigated the effectiveness of a distance learning educational model in oral-motor therapy for primary caregivers of children with neuromotor impairments in Mérida, Mexico. The quasiexperimental pretest-posttest design included thirty primary caregivers of children aged 2 to 12 with feeding and swallowing disorders from seven institutions. Twenty-three participants completed the program. The program encompassed theoretical sessions on various aspects of oral motor therapy and practical sessions focusing on hands on training. Results revealed substantial enhancements in theoretical knowledge and practical competencies among caregivers, with competence levels exceeding 80% in all evaluated activities. Despite these positive outcomes, the study acknowledges limitations such as a small sample size and the absence of a control group. Addressing these constraints through future research endeavors will bolster the evidence supporting the effectiveness of this innovative caregivercentric approach. Ultimately, integrating caregivers into the care team is imperative for improving the quality of life for children with neuromotor disabilities and effectively managing eating and swallowing disorders.

Os distúrbios da alimentação e da deglutição afetam significativamente a qualidade de vida das crianças com deficiências neuromotoras. A pandemia da COVID-19 exacerbou esses desafios desafios, sendo que limitou o acesso ao atendimento. Este estudo avaliou um modelo educacional de ensino à distância sobre terapia oral-motora, orientado a cuidadores primários de crianças com deficiências neuromotoras em Mérida, México. Trinta cuida- dores de crianças de 2 a 12 anos de idade com distúrbios de alimentação e deglutição de sete instituições participaram, sendo que 23 deles concluíram o programa. Um estudo quase experimental de préteste-pós-teste foi realizado. O programa incluiu sessões teóricas e práticas. Os resultados mostraram melhorias significativas no conhecimento teórico e nas competências práticas, com níveis de competência acima de 80%. Contudo, são reconhecidas algumas limitações do estudo, como o pequeno tamanho da amostra e a falta de um grupo de controle. A abordagem dessas limitações em pesquisas futuras fortalecerá as evidências respeito da eficácia dessa abordagem inovadora centrada no cuidador, crucial para melhorar a qualidade de vida das crianças com deficiências neuromotoras e gerenciar os distúrbios de alimentação e deglutição de forma eficaz.

Analysis of relationships between personality factors and the risk of Eating Disorders

Introduction: Regarding the origin of Eating Disorders, different psychological variables such as the personality, have been identified as risk factors for the onset and subsequent development of these pathologies. This study aimed to analyse the relationships between personality and different risk variables for the development of ED in the population of female students without disorders. Method: Participants included 627 women, Spanish university students, who completed the Eating Disorder Inventory-3 (EDI-3) and the Five-Factor Inventory (NEO-FFI). Correlation and regression analyses were conducted in order to observe patterns of common variation among the variables, and to determine the contribution of the personality traits in the explanation of the variables. Results: Neuroticism correlated significantly with all scales and is the main predictor of the risk scales (drive for thinness, bulimia and body dissatisfaction), and the seven psychological scales. The remaining factors showed negative correlations with all of the scales. Extraversion was the main predictor variable in the explained variance of interpersonal insecurity and interpersonal alienation. In addition, conscientiousness and agreeableness demonstrated an effect on different scales in combination with other factors. Conclusion: The study sustained the importance of personality in the risk of developing ED. Neuroticism is the factor that is most closely related to the risk variables and psychological constructs which are conceptually relevant in the development and maintenance of these disorders. The study of personality should help in identifying at-risk populations, and will enable adopting solutions aimed at the prevention of ED.

Introducción: En el origen de los trastornos alimentarios han sido identificadas diferentes variables psicológicas como factores de riesgo, como la personalidad, para el inicio y posterior desarrollo de estas patologías. El objetivo del estudio fue analizar las relaciones entre la personalidad y diferentes variables de riesgo para el desarrollo de trastornos alimentarios, en la población de mujeres universitarias sin trastornos. Método: Las participantes fueron 627 mujeres, estudiantes universitarias españolas, que completaron el Eating Disorder Inventory-3 (EDI-3) y el Five-Factor Inventory (NEO-FFI). Se realizaron análisis de correlación y regresión para observar los patrones de variación común entre las variables y para determinar la contribución de los rasgos de personalidad en la explicación de las variables. Resultados: El neuroticismo correlacionó significativamente con todas las escalas, y fue la principal variable predictiva en la varianza explicada de las escalas de riesgo (obsesión por la delgadez, bulimia e insatisfacción corporal), y siete escalas psicológicas. Los rasgos de personalidad restantes mostraron correlaciones negativas con todas las escalas. Extraversión fue la principal variable predictora de la varianza explicada de inseguridad interpersonal y alienación personal. Además, responsabilidad y amabilidad mostraron efecto en combinación con otros factores en diferentes variables. Conclusión: El estudio apoyó la importancia de la personalidad en el riesgo de desarrollar trastornos alimentarios. El neuroticismo es el factor que más se relaciona con las variables de riesgo y constructos psicológicos conceptualmente relevantes en el desarrollo y mantenimiento de estos trastornos. El estudio de la personalidad debería ayudar a identificar a las poblaciones de riesgo y adoptar soluciones dirigidas a la prevención.

A systematic review of the effects of nutrition programmes in high schools

Introduction/Objectives: Obesity rates are reaching alarming levels. Adolescence is a critical period for the prevention of nutritional problems, as it is a time of development of one's own eating habits. These habits will persist into adulthood, so showing adolescents healthy lifestyle patterns is important. The ideal option would be through school-based nutrition intervention programmes. The main objective of this article is to investigate the effectiveness of intervention programmes based on nutritional knowledge and the behaviour of adolescents aged 11-19 years. Method: To carry out this systematic review we employed Scopus, PubMed, and Web of Science as databases and a search period that spanned the last 10 years, following the PRISMA statement. Subsequent to the search, 110 articles were found. Finally, 19 articles were selected for in-depth analysis after a thorough screening. Results: The results show that, in general, intervention programmers have improved the nutritional knowledge of high school students, which means an improvement in their eating behaviours. In addition, these programmes increase their levels of physical activity. However, gender differences are observed, with girls being more concerned about maintaining a balanced diet. Conclusion: In conclusion, schools are an ideal environment for developing programmes that interfere in adolescent eating behaviour.

Introducción/Objetivos: Las tasas de obesidad están alcanzando niveles alarmantes. La adolescencia es un periodo crítico para la prevención de problemas nutricionales, ya que es un momento de desarrollo de los propios hábitos alimentarios. Estos hábitos permanecerán en la edad adulta, por lo que es importante mostrarles a los adolescentes patrones de estilo de vida saludable. La opción ideal sería a través de programas de intervención nutricional en las escuelas. El objetivo principal de este artículo es investigar la efectividad de los programas de intervención basados en el conocimiento y comportamiento nutricional en adolescentes de 11 a 19 años. Métodos: Para llevar a cabo esta revisión sistemática utilizamos como bases de datos Scopus, PubMed y Web of Science y un periodo de búsqueda que abarcó los últimos diez años, siguiendo la declaración Prisma. Después de la búsqueda, se encontraron 110 artículos. Finalmente, 19 artículos fueron seleccionados para un análisis en profundidad después de una revisión exhaustiva. Resultados: Los resultados muestran que, en general, los programas de intervención han mejorado los conocimientos nutricionales de los estudiantes de secundaria, lo que significa una mejora en sus conductas alimentarias. Además, estos programas aumentan sus niveles de actividad física. Sin embargo, se observan diferencias de género, estando las chicas más preocupadas por mantener una dieta equilibrada. Conclusiones: En conclusión, las escuelas son un ambiente ideal para el desarrollo de programas que interfieren en la conducta alimentaria de los adolescentes.

Impacto de la pandemia por COVID-19 en la conducta alimentaria de niñas, niños y adolescentes con trastorno del espectro autista / Impact of the COVID-19 pandemic on the eating behaviors of children and adolescents with autism spectrum disorder

Introducción. Los niños con trastorno del espectro autista (TEA) presentan dificultades de adaptación a situaciones estresantes, como la pandemia por COVID-19. Objetivo. Evaluar el impacto del primer año de pandemia en las dificultades alimentarias de niños con TEA. Población y métodos. Se invitó a participar a cuidadores de niños con TEA no sindromático (edad: 2-18 años) de una unidad de neurodesarrollo. Los participantes respondieron en línea un cuestionario y la escala de evaluación de problemas de conducta alimentaria (BPFAS por su sigla en inglés) antes y durante el primer año de pandemia. Se calculó un puntaje de prioridad (producto entre promedio de frecuencia y problema) para cada ítem del BPFAS. Resultados. El 56,6 % (86/152) de los cuidadores contestó la encuesta (madre 74,4 %), mediana de edad 6,3 años (p25-p75: 4,7-8,2); el 80,2 % de los niños eran de sexo masculino; el 58,1 % mantuvo terapia durante la pandemia y el 61,6 % presentaba problemas de comportamiento previo a esta. Durante el primer año de pandemia, los niños presentaron mayor intensidad en dificultades conductuales (34,9 %) y de alimentación (61,6 %); sin embargo, el 31,4 % refirió mejoría en la alimentación. No existieron diferencias significativas entre puntajes BPFAS antes y durante la pandemia. Los ítems con mayor puntaje de prioridad fueron "se levanta de la mesa durante la hora de comer", "no probar alimentos nuevos", "no come verduras", "no come frutas". Conclusiones. Hubo alta frecuencia de dificultades en las conductas alimentarias durante el primer año de pandemia. No se presentaron diferencias en las características de estas conductas antes y durante la pandemia.

Introduction. Children with autism spectrum disorder (ASD) have difficulties adapting to stressful situations, such as the COVID-19 pandemic. Objective. To assess the impact of the first year of the pandemic on feeding difficulties in children with ASD. Population and methods. The caregivers of children and adolescents with non-syndromic ASD (age: 2­18 years) from a neurodevelopment unit were invited to participate. Participants completed a questionnaire and the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) online before and during the first year of the pandemic. A priority score (product between the average frequency and the problem) for each BPFAS item was estimated. Results. Among the caregivers, 56.6% (86/152) completed the survey (mother: 74.4%); children's median age was 6.3 years (p25­p75: 4.7­8.2); 80.2% of children were males; 58.1% continued with their therapy during the pandemic; and 61.6% had behavioral problems before the pandemic. During the first year of the pandemic, children had greater behavioral problems (34.9%) and feeding difficulties (61.6%); however, 31.4% of caregivers referred improvements in feeding. There were no significant differences in the BPFAS scores before and during the pandemic. The following items obtained the highest priority scores: gets up from table during meal, does not try new food, does not eat vegetables, does not eat fruits. Conclusions. A high frequency of feeding difficulties was noted during the first year of the pandemic. No differences were observed in feeding characteristics before and during the pandemic.

Repercussões da Pandemia de COVID-19 no Tratamento de Pacientes com Anorexia/Bulimia: Revisão de Escopo / Repercussions of the COVID-19 Pandemic on the Treatment of Patients with Anorexia and Bulimia: Scoping Review

A emergência sanitária deflagrada pela pandemia de COVID-19 exigiu que os serviços de saúde especializados na assistência aos Transtornos Alimentares se adaptassem às novas circunstâncias impostas pela necessidade de distanciamento social. Considerando essa perspectiva, delineou-se uma revisão de escopo com objetivo de analisar as estratégias de cuidado adotadas por profissionais da saúde para garantirem a continuidade do atendimento interdisciplinar aos pacientes em tempos de COVID-19. Foram consultadas as bases Web of Science, Scopus, PubMed/MEDLINE, CINAHL, PsycINFO, Embase, LILACS e SciELO entre 2020 e 2022. Identificaram-se 387 registros nas bases de dados, dos quais 11 preencheram os critérios de elegibilidade e foram selecionados. Os resultados foram organizados em três categorias temáticas: (1) a "não escolha" da escolha do formato online: prós e contras; (2) foco na comunicação e acolhimento: ressignificando o uso do dispositivo online; (3) intervenções online: adaptações, inovações e recursos alternativos. As principais estratégias utilizadas durante a transição do tratamento para o ambiente online foram: teleatendimento e psicoterapia online. Apesar de terem sido bem avaliadas, foram percebidas barreiras para superar as limitações do cuidado online, como a desconfiança dos pacientes e seus potenciais efeitos na qualidade do vínculo terapêutico.

The health emergency triggered by the COVID-19 pandemic demanded that health services specialized in treating Eating Disorders adapt to the new circumstances imposed by social distancing. Considering this perspective, a scoping review was designed with the objective of analyzing the care strategies adopted by health professionals to maintain continuity of interdisciplinary care to patients in times of COVID-19. The Web of Science, Scopus, PubMed/MEDLINE, CINAHL, PsycINFO, Embase, LILACS, and SciELO databases were queried. A total of 387 records were identified in the databases, of which 11 met the eligibility criteria and were selected. The results were organized into three thematic categories: (1) the "non-choice" of choosing the online format: pros and cons; (2) focus on communication and welcoming: resignifying the use of the online device; (3) online interventions: adaptations, innovations and alternative resources. The main strategies used during the transition of the treatment to the online environment were: telehealth and online psychotherapy. Although well evaluated, barriers to overcome the limitations of online care were perceived, such as patients' distrust and its potential effects on the quality of the therapeutic bond.

Emociones autoconscientes relacionadas con el cuerpo y la apariencia y sintomatología de trastornos de la conducta alimentaria en una muestra de hombres adultos / Body and appearance-related self-conscious emotions and eating disorder symptoms in a sample of adult men

Abstract: In recent years, the number of men suffering from an Eating Disorder (ED) has increased. However, very few studies on ED have been conducted in samples of men. This paper aims to shed some light on this issue by exploring the following questions in a sample of adult men: 1) to analyse the relationships between body and appearance-related self-conscious emotions and ED symptomatology and, 2) to study the differences between a group of men who are at risk of developing an ED and another group of men who are not at risk of developing an ED in body and appearance-related self-conscious emotions. A total of 207 Spanish or Latin American men aged 18-50 years participated. Men who were at risk of developing an ED had more body shame and body guilt than those who were not at risk. However, no statistically significant differences were found between the two groups in body pride. These findings show that, unlike in women, body pride does not seem to play as important a role in these disorders as body shame or body guilt.

Resumen: En los últimos años, ha aumentado el número de hombres que padecen un Trastorno de la Conducta Alimentaria (TCA). Sin embargo, apenas se han realizado estudios sobre TCA con muestras de hombres. Este trabajo pretende arrojar algo de luz a este respecto, explorando las siguientes cuestiones en una muestra de hombres adultos: 1) analizar las relaciones entre las emociones autoconscientes asociadas al cuerpo y a la apariencia y la sintomatología de TCA y, 2) estudiar las diferencias entre un grupo de hombres que están en riesgo de desarrollar un TCA y otro grupo de hombres que no presentan dicho riesgo en las emociones autoconscientes asociadas al cuerpo y a la apariencia. Participaron 207 hombres de entre 18 y 50 años de nacionalidad española o latinoamericana. Los hombres que estaban en riesgo de desarrollar un TCA presentaron más vergüenza corporal y culpa corporal que aquellos que no tenían dicho riesgo. Sin embargo, no se encontraron diferencias estadísticamente significativas entre ambos grupos en el orgullo corporal. Estos hallazgos muestran que, a diferencia de lo que ocurre en mujeres, el orgullo corporal no parece desempeñar un papel tan relevante en estos trastornos como el que tienen la vergüenza corporal o la culpa corporal.

Impacto del uso de plataformas de video llamadas en las preocupaciones con la apariencia física en pacientes con Trastornos Alimentarios y de la población general durante la Pandemia por COVID 19 / Video call platforms impact on physical appearance concerns in patients with Eating Disorders and general population during the COVID 19 Pandemic

Resumen: Objetivo: Explorar el impacto del uso cotidiano de plataformas de videollamadas en las cogniciones, emociones y comportamientos relacionados con la autoimagen en pacientes con Trastornos del Comportamiento Alimentario (TCA) y personas de la población general, durante la pandemia por COVID-19. Métodos: Sesenta y ocho pacientes con TCA en tratamiento y 106 personas de la población general respondieron a un cuestionario diseñado para el estudio a través de Lime Survey; (98.5 y 79.2% respectivamente eran mujeres), con edad promedio de 17.6 (DE:3.47) y 33.5 (DE:9.35) respectivamente. Las pacientes discutieron y explicaron sus respuestas en cinco sesiones de terapia grupal presenciales dirigidas por un psiquiatra. Posteriormente, se realizó un análisis temático reflexivo con un enfoque inductivo para determinar las categorías. Resultados: Los pacientes reportaron una mayor incomodidad frente a la cámara, preocupación con la apariencia física, miedo a la crítica, vergüenza y sentimientos de vulnerabilidad, comparados con las personas de la población general. Predominaron los pensamientos negativos sobre la forma y el tamaño del rostro y otras partes del cuerpo y las conductas de chequeo y/o evitación de la imagen corporal, que interfirieron con la concentración y el rendimiento. Conclusión: además del impacto negativo de la pandemia de COVID-19 en la salud mental, la nueva virtualidad desafía a los clínicos a enfrentar dificultades adicionales con la imagen corporal en pacientes con TCA y alerta a la detección de nuevas preocupaciones dismórficas también en la población general.

Abstract: Objective: To explore the impact of video call platforms on physical appearance concerns (cognitions, emotions and behaviors) in Eating Disorders (ED) patients and in general population, during COVID 19 pandemic. Methods: Sixty-eight patients attending a treatment program for ED, and 106 people from the general population responded to a questionnaire designed for the study through Lime Survey; (98.5 and 79.2% respectively were women), with a mean age of 17.6 (SD:3.47) and 33.5 (SD:9.35) respectively. Patients discussed and explained their answers in five in vivo group therapy sessions directed by a psychiatrist. Then, a reflective thematic analysis with an inductive approach to determine the categories was performed. Results: Patients reported a higher discomfort in front of the camera, preoccupation with physical appearance, fear of criticism, embarrassment, and feelings of vulnerability, compared with general population. Negative thoughts about the shape and size of the face and other body parts predominated, as well as body image checking/avoidance behaviors that interfered with concentration and performance. Conclusion: In addition to the negative impact of the COVID-19 pandemic on mental health, the new virtuality challenges clinicians to face additional body image difficulties in ED patients and alerts on the detection of dysmorphic concerns in the general population as well.

Relación entre resiliencia y conductas alimentarias de riesgo / Relationship between resilience and risk eating behaviors

Resumen: Los trastornos de la conducta alimentaria son de las enfermedades crónicas más frecuentes en adolescentes y mujeres jóvenes. En México se han encontrado porcentajes desde 5 hasta 18% de conductas alimentarias de riesgo en muestras de mujeres estudiantes universitarias (Unikel-Santoncini, et al., 2004). Por otro lado, la resiliencia se define como un constructo que incluye ciertos fenómenos que consisten en la adecuada adaptación del individuo ante situaciones traumáticas, privación extrema, amenazas graves o estrés elevado (González-Arratia, 2008, en Camacho-Valadez, 2016). Esta investigación examina la relación entre la resiliencia y las conductas alimentarias de riesgo por medio de la aplicación de los instrumentos EAT-26 y RESI-M a 201 mujeres mexicanas, con un promedio de edad de 22 años. Se realizó un análisis de correlación de Producto Momento de Pearson, el cual demostró que, aquellas mujeres con mayores niveles de resiliencia mostraban menos conductas alimentarias de riesgo. Se propone realizar el mismo estudio con poblaciones más jóvenes, así como con participantes de sexo masculino.

Abstract: Eating disorders are one of the most frequent chronic diseases in adolescents and young women. In Mexico, percentages from 5 to 18% of risk eating behaviors have been found in samples of female university students (Unikel-Santoncini, et al., 2004). On the other hand, resilience is defined as a construct that includes certain phenomena that consist of the individual's adequate adaptation to traumatic situations, extreme deprivation, serious threats, or high stress (González-Arratia, 2008, in Camacho Valadez, 2016). This research examines the relationship between resilience and risk eating behaviors through the application of the EAT-26 and RESI-M instruments to 201 Mexican women, with an average age of 22 years. A Pearson Product Moment correlation analysis was performed, which showed that those women with higher levels of resilience showed less risk eating behaviors. It's proposed to carry out the same study with younger populations, as well as with male participants.

Terapia de remediación cognitiva en bulimia nerviosa: Un estudio de caso / Cognitive remediation therapy in bulimia nervosa: A case study

Resumen El objetivo de este estudio fue realizar una evaluación preliminar de la terapia de remediación cognitiva (TRE) en una paciente con bulimia nerviosa (BN). Bajo un diseño pre-post-tratamiento, la paciente (20 años de edad e índice de masa corporal [IMC] de 22.41) completó cuatro pruebas neuropsicológicas, tres medidas de síntomas de BN y dos de sintomatología psiquiátrica (depresión y ansiedad). Con base a las puntuaciones pre y post TRE fue calculado el cambio clínico objetivo (CCO). Los principales efectos neuropsicológicos se registraron en: flexibilidad de pensamiento, proceso visocontructivo, coherencia central y planificación (CCO = 0.39-0.99). También se identificaron cambios relevantes en las medidas de sintomatología psiquiátrica y de BN (CCO = 0.53-0.88), no así en el IMC. Este estudio suma evidencias respecto a la utilidad de la CRT en el tratamiento multidisciplinario, ya no solo de la anorexia nerviosa, sino que extiende su aplicabilidad a la BN.

Abstract The aim of this study was to perform a preliminary evaluation of cognitive remediation therapy (CRT) in a patient with bulimia nervosa (BN). The participant was 20 years old with a 22.41kg/m2 body mass index (BMI). Under a pre-post treatment design, the patient was administered four neuropsychological tests, three measures of BN symptoms and two of psychiatric symptomatology (depression and anxiety). Based on the pre and post CRT scores, the objective clinical change (OCC) was calculated. The main neuropsychological effects were observed in cognitive flexibility, visoconstructive processing (memory and central coherence) and working memory (OCC = 0,39-0,99). Relevant changes were also identified in the measures of psychiatric symptomatology and BN (OCC = 0,53-0,88), with no change in BMI. This study adds evidence regarding the usefulness of CRT in the multidisciplinary treatment not only of anorexia nervosa, but also extends its applicability to another eating disorder, BN.

Avoidant restrictive eating disorder and panic attacks in an adult man: A case report / Trastorno evitativo restrictivo de la ingesta alimentaria y ataques de pánico en un hombre adulto: Reporte de caso

Abstract Avoidant or Restrictive Food Intake Disorder (ARFID) is an eating disorder (ED) not common in adults. In this article we present a clinical case of ARFID in a 37-year-old male patient treated in an ED center in Medellin, Colombia; displaying anxious symptoms that began a year earlier and concomitant weight loss, following a traumatic event causing an overall impairment with that patient. Several medical evaluations/examinations looking for organic causes, were excluded. Interventions were implemented by a psychiatry, a psychotherapist using cognitive-behavior therapy (CBT), and a nutritionist, all in face-to-face modality, which were carried out weekly for the first three months, then biweekly and subsequently quarterly. each lasting approximately 40-60 minutes. After the set of pharmacological interventions and psychotherapy, a great improvement in the functionality of the patient was observed. Improvement was found with respect to eating in public, food variation and panic attacks. In the absence of guidelines, it is important to use standardized and replicable treatments in this population.

Resumen El trastorno evitativo restrictivo de la ingesta (TERIA) es un trastorno alimentario (TCA) raro en adultos. Se presenta el caso de un hombre de 37 años con TERIA y trastorno de pánico atendido en un centro para TCA en Medellín, Colombia, quien presentó un año de síntomas ansiosos y pérdida de peso después de evento traumático, generando disfuncionalidad. Fue evaluada y excluida organicidad. Se realizaron intervenciones por parte de psiquiatría, psicoterapia con enfoque cognitivo conductual y nutrición, todas en modalidad presencial, las cuales se realizaron semanalmente los primeros tres meses, luego quincenalmente y posteriormente trimestralmente. Cada una con una duración de 40-60 minutos aproximadamente por sesión. Posterior al conjunto de intervenciones farmacológicas y psicoterapia, se observó una gran mejoría la funcionalidad del paciente, se encontró mejoría con respecto a comer en público, variación en los alimentos y ataques de panico. Ante la ausencia de guías de manejo de TERIA en adultos es relevante realizar tratamientos estandarizados que puedan ser replicados.

Hábitos de alimentación infantil y su relación con las prácticas y conocimientos nutricionales parentales

Objetivo: Evaluar la relación entre las prácticas parentales de alimentación, los conocimientos nutricionales de los padres y los hábitos de alimentación infantil reportados por padres de cuatro instituciones educativas del suroccidente de Colombia. Método: Estudio observacional con diseño transversal correlacional. Se analizaron los datos de 1.162 padres de niñas y niños matriculados en los grados de preescolar hasta tercero de primaria de cuatro instituciones educativas públicas, quienes contestaron cuestionarios de autoinforme. Se realizaron análisis descriptivos e inferenciales. Resultados: La dieta de las niñas y los niños se caracteriza por un consumo frecuente de alimentos ultraprocesados y un consumo de frutas y verduras menor de lo esperado. Se encontraron relaciones entre las prácticas parentales de alimentación responsivas y el consumo de alimentos saludables en los hijos, así como entre las prácticas autoritarias y permisivas con el consumo frecuente de alimentos ultraprocesados. El nivel de conocimiento nutricional de los padres no se relacionó con la dieta de las niñas y los niños; sin embargo, se encontró una relación entre las prácticas parentales responsivas, un bajo nivel de conocimientos nutricionales de los padres y una baja frecuencia de consumo de frutas y verduras en los hijos. Conclusión: La alimentación es un fenómeno complejo, e implica la interacción entre los factores individuales y contextuales; en esta medida, la promoción de hábitos saludables involucra un trabajo conjunto en los múltiples niveles de interacción. Se espera que los resultados de este estudio posibiliten la construcción de intervenciones interdisciplinares oportunas, en poblaciones de bajos y medios ingresos en el territorio observado.

Purpose: To evaluate the relationship between parental feeding practices, parental nutritional knowledge, and child feeding habits reported by parents in four educational institutions in southwestern Colombia. Method: Observational study with correlational cross-sectional design. Data were analysed from 1.162 parents of children enroled in grades from preschool to third grade from four public educational institutions. Parents answered self-report questionnaires. Descriptive and inferential analyses were performed. Results: The children's diet is characterised by frequent consumption of ultra-processed food and a lower consumption of fruits and vegetables. Relationships were found between responsive parenting practices and healthy food consumption in children, as well as between authoritarian and permissive practices with frequent consumption of ultra-processed foods. The level of nutritional knowledge of parents was not related to the children's diet; however, a relationship was found between responsive parenting practices, a low level of nutritional knowledge of parents, and a low frequency of fruit and vegetable consumption in children. Conclusion: Eating is a complex phenomenon and involves the interaction between individual and contextual factors. To this extent, the promotion of healthy habits involves joint work at multiple levels of interaction. The results of this study are expected to allow the construction of timely interdisciplinary interventions in low- and middle-income populations in the observed territory.

Calidad de la dieta y estado nutricional de un grupo de estudiantes de una Universidad Pública de Paraguay

Introducción: La calidad de la dieta se refiere a la composición nutricional y equilibrio de los alimentos consumidos, lo que puede influir en la salud y bienestar a largo plazo. El objetivo de este estudio fue evaluar la calidad de la dieta y el estado nutricional en estudiantes de una universidad pública de Paraguay. Materiales y métodos: Estudio transversal descriptivo realizado en estudiantes universitarios. Se recolectaron dos recordatorios de 24 horas en días no consecutivos, mediante metodología de pasos múltiples, para clasificar la calidad de la dieta (muy baja, baja, moderada, buena) de acuerdo con el índice de calidad de la dieta (DQI). Se tomaron medidas antropométricas (peso talla, circunferencia de cintura) y de composición corporal, para determinar el estado nutricional. Se utilizó estadística descriptiva y pruebas estadísticas como Chi2 y prueba exacta de Fisher. El protocolo fue aprobado por la Dirección de Investigaciones, UNA_FCM_DI N° 262/2021. Resultados: Participaron 39 estudiantes universitarios, de los cuales 31 eran mujeres. El 64,1% tenía menos de 25 años y 21 (53,8%) estaban en carreras de salud. Se observó que el 64,1% de los estudiantes tenían una baja o muy baja calidad de la dieta, el 33,3% una calidad moderada y el 2,6% una calidad buena. Además, 17 estudiantes presentaron exceso de peso (43,6%) y 19 se encontraban en normopeso (48,7%). Se destacó que el 68,2% de los estudiantes sin exceso de peso tenían una dieta de baja o muy baja calidad. Conclusión: Los estudiantes universitarios evaluados en este estudio presentaron baja calidad de la dieta y desequilibrio en el aporte de macronutrientes. A pesar de esto, el estado nutricional más frecuente fue el normopeso. Se destaca la importancia de promover intervenciones para mejorar la calidad de la dieta y fomentar hábitos saludables en esta población.

Introduction: Diet quality refers to the nutritional composition and balance of the consumed foods, which can influence health and well-being in the long term. This study aimed to evaluate the diet quality and nutritional status among students at a public university in Paraguay. Materials and methods: A descriptive cross-sectional study was conducted among university students. Two 24-hour recalls were collected on non-consecutive days, using the multi-step methodology, to classify diet quality (very low, low, moderate, good) according to the Diet Quality Index (DQI). Anthropometric measurements (weight, height, waist circumference) and body composition were taken to determine the nutritional status. Descriptive statistics and statistical tests such as Chi2 and Fisher's exact test were used. The protocol was verified by the Research Directorate, UNA_FCM_DI N° 262/2021. Results: 39 university students participated, of which 31 were females. 64,1% were under 25 years old and 21 (53,8%) were enrolled in health-related careers. It was observed that 64,1% of the students had poor or very poor diet quality, 33,3% had moderate quality and 2.6% a good quality. Additionally, 17 students were overweight (43,6%) and 19 were within the normal weight range (48,7%). It was highlighted that 68,2% of the students with no excess weight had a diet of poor or very poor quality. Conclusion: The university students evaluated in this study presented poor diet quality and imbalance in macronutrients intake. Despite this, the most frequent nutritional status was within the normal weight range. The importance of promoting interventions to improve diet quality and promote healthy habits in this population is highlighted.

Jogo da alimentação saudável: tecnologia de prática educativa para crianças com Síndrome de Down / Healthy eating game: educational practice technology for children with Down Syndrome

O objetivo foi desenvolver uma Tecnologia Educacional sobre alimentação saudável para crianças com Síndrome de Down. Estudo metodológico realizado em três etapas, iniciado com a revisão narrativa da literatura e o diagnóstico situacional na APAE-Belém, com pais ou responsáveis de crianças com SD ao participaram de uma entrevista. Como resultado, após o procedimento de análise e a interpretação dos achados, foram identificadas três categorias: alimentação saudável, alimentação da criança e a tecnologia educacional sobre alimentação saudável. Na segunda etapa ocorreu a pré-produção e na terceira etapa a produção final do protótipo do jogo de tabuleiro intitulado "Meu prato pai d'égua". Com a evolução do estudo concluiu-se que a produção de TE sensíveis à realidade desses indivíduos, possibilita a inovação de dispositivos convergentes com suas necessidades e demandas, gerando um efeito positivo no que tange aos saberes relacionados à alimentação saudável e educação em saúde.

The objective was to develop an Educational Technology on healthy eating for children with Down Syndrome. Methodological study carried out in three stages, starting with the narrative review of the literature and the situational diagnosis in theAPAE-Belém, with pparents or guardians of children with DS when participating in an interview. As a result, after the analysis procedure and interpretation of the findings, three categories were identified: healthy eating, children's eating and educational technology about healthy eating. In the second stage, pre-production took place and in the third stage, the final production of the board game prototype entitled "MI dish it, father of mare". As the study progressed, it was concluded that the production of TEs that are sensitive to the reality of these individuals enables the innovation of devices converging with their needs and demands,generating a positive effect in terms of knowledge related to healthy eating and health education.

Association between Variables of Eating Habits and Gastric Trophic Changes in a Gastroenterology Institution in Medellín, Colombia

Aim: To establish the relationship between consuming foods considered risk factors for gastric cancer and trophic changes in gastric mucosa. Materials and methods: Cross-sectional study. We included patients older than 18 admitted for upper GI endoscopy with biopsies who adequately answered a survey of personal history and eating habits. Those with a history of gastric cancer or gastric surgical resection for any reason were excluded. The association between feeding variables and trophic changes in the gastric mucosa was estimated. Results: In a population of 1,096 patients, the average age was 51 years (standard deviation [SD]: 15.5), and 59% were women. Trophic changes in the gastric mucosa were identified in 173 patients (15.8%). No statistical association was found between the independent variables of eating habits, obesity, and positive Helicobacter pylori versus the variable "trophic changes," unlike the variable "family history of gastric cancer" (odds ratio [OR]: 1.49 95% confidence interval [CI]: 1.03-2.17, p = 0.036). One case of high-grade dysplasia was detected in the study population (0.91 cases in 1,000 patients). Conclusions: No association was established between eating habits and trophic changes in the gastric mucosa in the studied population. A family history of gastric cancer is a statistically significant risk factor for developing atrophy, metaplasia, or dysplasia changes.

Objetivo: establecer la relación entre el consumo de alimentos considerados como factores de riesgo para cáncer gástrico y la presencia de cambios tróficos de la mucosa gástrica. Materiales y métodos: estudio de corte transversal. Se incluyeron los pacientes mayores de 18 años admitidos para realización de endoscopia digestiva superior con toma de biopsias que respondieron adecuadamente una encuesta de antecedentes personales y hábitos de alimentación. Se excluyeron aquellos con antecedente de cáncer gástrico o resección quirúrgica gástrica por cualquier motivo. Se estimó la asociación entre las variables de alimentación y la presencia de cambios tróficos de la mucosa gástrica. Resultados: en una población de 1096 pacientes, el promedio de la edad fue 51 años (desviación estándar [DE]: 15,5), y correspondió en un 59% a mujeres. Se identificaron cambios tróficos de la mucosa gástrica en 173 pacientes (15,8%). No se obtuvo asociación estadística entre las variables independientes de hábitos de alimentación, obesidad y Helicobacter pylori positivo frente a la variable "cambios tróficos", a diferencia de la variable "antecedente familiar de cáncer gástrico" (odds ratio [OR]: 1,49; intervalo de confianza [IC] 95%: 1,03-2,17; p = 0,036). Se obtuvo 1 caso de displasia de alto grado en la población estudiada (0,91 casos en 1000 pacientes). Conclusiones: no se estableció una asociación entre los hábitos de alimentación y la presencia de cambios tróficos de la mucosa gástrica en la población estudiada. El antecedente familiar de cáncer gástrico se muestra como un factor de riesgo estadísticamente significativo para el desarrollo de cambios de atrofia, metaplasia o displasia.
