[Exploring Needs, Motivations, and Limitations Towards Healthy Eating and Digital Resources: A Qualitative Study in a Mexican Primary Education Setting]. / Exploración de necesidades, motivaciones y limitaciones en relación con la alimentación saludable y recursos digitales: un estudio cualitativo en un entorno de educación primaria en México.

OBJECTIVE: To explore the needs, motivations, and limitations related to healthy eating and digital materials, as well as to identify patterns for their design as a strategy aimed at Mexican families. DESIGN: A qualitative observational study of the phenomenon through focus group sessions. LOCATION: A public primary education center in the city of Querétaro, Mexico. PARTICIPANTS: Children aged 9 to 11 years and parents, mothers, or caregivers with children in primary education. METHOD: Twelve sessions were conducted with three groups of students and two sessions with parents, mothers, or caregivers using an interview guide. Various digital materials, developed based on social cognitive theory, were presented during the sessions. The sessions were recorded with the participants' or their guardians' prior consent and transcribed for analysis. Coding was performed for key points of analysis, and information saturation was confirmed. RESULTS: Students expressed motivation towards digital material that promotes play and experimentation, especially within the family context. The main perceived barrier was the caregivers' resistance to change. Parents expressed motivation and a need for explanatory material on diseases, with economic and time-related barriers. CONCLUSIONS: Digital material based on social cognitive theory, designed to improve nutrition, can be an effective strategy in nutritional education if it considers the circumstances of the target population. It is advisable to include affective and behavioral elements to achieve meaningful learning within households.

Plan técnico para la ejecución de la "Jornada a nivel nacional de acciones integrales e intersectoriales para lucha contra las Arbovirosis en Centros Escolares y Centros de Votación 2024" / Technical plan for the implementation of the "National day of comprehensive and intersectoral actions to combat Arbovirosis in Schools and Voting Centers 2024

En la situación del dengue en El Salvador, inciden determinantes (ambientales, económicos, políticos y sociales), la constante migración del campo a la ciudad, una creciente urbanización sin planificación ni regulación alguna, pobreza, inequidad en el ingreso y condiciones de exclusión que relegan a la población en esta situación a exponerse permanentemente a condiciones de alto riesgo y vulnerabilidad que favorecen la persistencia de la transmisión de arbovirosis, entre ellos se pueden señalar crecimiento poblacional, construcción de viviendas inadecuadas que generan condiciones críticas de hacinamiento, deficiente abastecimiento de agua que obliga a las personas a almacenarla inadecuadamente, una deficiente recolección de desechos sólidos, todo lo cual genera condiciones adecuadas para la multiplicación del Aedes aegypti y la transmisión de la enfermedad. El Ministerio de Salud, anticipándose al retorno de alumnos a un aproximado de 5,000 centros escolares públicos y privados, además de la prevención en 1,600 centros de votación, se ha programado la ejecución de una jornada a nivel nacional de acciones, la cual tiene por objetivo el control del vector en su fase larvaria y adulta; así como, la realización de acciones gubernamentales de carácter preventivas, en el que se realizarán actividades de promoción de la salud encaminadas a la eliminación de criaderos y otras actividades que sean factibles de desarrollar por la comunidad.

In the situation of dengue in El Salvador, determinants (environmental, economic, political and social), the constant migration from the countryside to the city, a growing urbanization without any planning or regulation, affect poverty, inequity in income and conditions of exclusion that relegate the population in this situation to be permanently exposed to conditions of high risk and vulnerability that favor the persistence of transmission of arbovirosis, These include population growth, construction of inadequate housing that generates critical conditions of overcrowding, poor water supply that forces people to store it improperly, poor solid waste collection, all of which generates adequate conditions for the multiplication of Aedes aegypti and the transmission of the disease. The Ministry of Health, anticipating the return of students to approximately 5,000 public and private schools, in addition to prevention in 1,600 voting centers, has scheduled the execution of a day at the national level of actions, which has as its objective the control of the vector in its larval and adult phase; as well as the carrying out of preventive governmental actions, which will include health promotion activities aimed at the elimination of hatcheries and other activities that are feasible to develop by the community

Vitimização por bullying e fatores associados entre escolares de um município do Sul do Brasil / Bullying victimization and associated factors among schoolchildren in a city in the south of Brazil

Resumo O objetivo foi avaliar a prevalência de vitimização por bullying e seus fatores associados entre adolescentes da cidade de Pelotas, RS. Estudo transversal de base escolar realizado com 795 alunos do 9o ano do ensino fundamental de 25 escolas municipais urbanas vinculadas ao PSE. O bullying foi avaliado por meio de perguntas que abordaram a ocorrência, a frequência, o local, o tipo de violência sofrida e o quanto isso incomoda as vítimas. Análises bruta e ajustada foram feitas por regressão de Poisson. Aproximadamente 71% dos estudantes relataram ter sofrido bullying, a escola foi o local de maior ocorrência (86,7%). Entre os tipos de agressões sofridas, "apelidos" foi a queixa mais recorrente (88,4%), seguida por exclusão ou isolamento (26,6%). A vitimização foi mais frequente entre as meninas (RP 1,13; IC95% 1,02-1,27), estudantes com cor da pele/raça não branca (RP 1,16; IC95% 1,05-1,29), que já experimentaram tabaco (RP 1,14; IC95% 1,03-1,27), insatisfeitos (RP 1,42; IC95% 1,27-1,58) ou indiferentes (RP 1,21; IC95% 1,02-1,43) em relação ao corpo e que apresentavam excesso de peso (RP 1,15; IC95% 1,04-1,27). Os resultados mostram que o bullying é uma prática frequente no ambiente escolar, apontando para a necessidade de práticas educativas voltadas para a redução e prevenção desse tipo de violência.

Abstract The objective was to assess the prevalence of bullying victimization and associated factors among adolescents in the city of Pelotas, Rio Grande do Sul. A cross-sectional school-based study was conducted with 795 ninth grade students from 25 urban municipal schools linked to the School Health Program. Bullying was assessed using questions that addressed the occurrence, frequency, location, type of violence suffered and how much it bothers the victims. Gross and adjusted analyses were performed by Poisson regression. Approximately 71% of the students reported having suffered bullying, and school was the location of greatest occurrence (86.7%). Among the types of aggression suffered, "nicknames" was the most recurrent complaint (88.4%), followed by exclusion or isolation (26.6%). Victimization was more frequent among girls (PR 1.13; 95%CI 1.02-1.27), students with non-white skin color/race (PR 1.16; 95%CI 1.05-1.29), who have already tried tobacco (PR 1.14; 95%CI 1.03-1.27), dissatisfied (PR 1.42; 95%CI 1.27-1.58) or indifferent (PR 1.21; 95%CI 1.02-1.43) about their bodies, and who were overweight (PR 1.15; 95%CI 1.04-1.27). The results show that bullying is a frequent practice in the school environment, pointing to the need for educational practices aimed at reducing and preventing this type of violence.

Effect of school reopening on pediatric morbidity and mortality during the third epidemiological wave of COVID-19 in a Mexican state / Efecto de la reapertura de escuelas en la morbimortalidad pediátrica durante la tercera ola epidemiológica por COVID-19 en un estado mexicano

Abstract Background: Determining the effect of reopening schools on pediatric SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection rates increased the need to share the experience of governments in many geographic regions for better future decision-making in similar health emergencies. Methods: Through a prospective study based on a population-based cohort, students from 18,988 schools in the State of Mexico who began returning to school were followed. Daily sanitation filters were implemented in each school and district liaisons were informed on a daily basis through a negative network. Identified cases were confirmed by reverse transcriptase-polymerase chain reaction. Simple case frequencies, percentages, and incidences of COVID-19 were estimated. State incidences were compared with the national incidence. Results: A total of 3,586 cases were confirmed; 2,048 (57.1%) were children. Twenty-four (0.6%) were hospitalized for moderate to severe COVID-19; nine (37.5%) died, and only one was a schoolchild. From week 36, an average infection rate of 0.36 was observed. The highest infection rate in schoolchildren was observed in epidemiologic week 40 (1.01); from this week on, a decrease in the number of cases was observed until week 50. Conclusions: The use of non-pharmaceutical interventions has more advantages than limitations, as long as the strategies are homogeneous and properly implemented to ensure adequate control of infections.

Resumen Introducción: La determinación del efecto de reabrir las escuelas sobre las tasas de infección pediátrica por SARS-CoV-2 (síndrome respiratorio agudo grave coronavirus 2) incrementó la necesidad de trasmitir la experiencia de los gobiernos de muchas regiones geográficas para mejores decisiones futuras en emergencias sanitarias similares. Métodos: Mediante un estudio prospectivo basado en una cohorte poblacional se dio seguimiento a los alumnos de 18,988 escuelas del Estado de México que iniciaron con el regreso a clases. Se implementaron filtros sanitarios diarios en cada escuela y cotidianamente se informaban a los enlaces jurisdiccionales a través de una red negativa. Los casos identificados eran confirmados a través de RT-PCR (reacción en cadena de la polimerasa con transcriptasa inversa). Se estimaron frecuencias simples de casos, porcentajes e incidencias de COVID-19. Las incidencias del estado se compararon con la incidencia nacional. Resultados: Un total de 3,586 casos fueron confirmados; 2,048 (57.1%) correspondieron a niños. Veinticuatro (0.6%) fueron hospitalizados por COVID-19 moderado a grave; nueve (37.5%) fallecieron, y solamente una correspondió a un escolar. A partir de la semana 36 se observó una tasa promedio de infecciones de 0.36. En la semana epidemiológica 40 se observó la mayor tasa de infección en escolares (1.01); a partir de esta semana se observa un declive de los casos hasta la semana 50. Conclusiones: La implementación de intervenciones no farmacéuticas tiene más ventajas que limitaciones, siempre y cuando las estrategias sean homogéneas y correctamente ejecutadas, lo que asegurará un adecuado control en los contagios.

Análisis de la coordinación motora por Índice de Masa Corporal y sexo en escolares de Chile

La investigación tuvo como objetivo analizar la relación entre la Coordinación Motora (CM) con el Índice de Masa Corporal en escolares chilenos de entre 7 y 9 años. El estudio fue observacional de corte transversal, con características descriptivas y correlacionales. Se evaluaron a 180 escolares (90 mujeres de 8.4 ± 0.9 años y 90 hombres de 8.5± 0.9 años). Se midieron variables antropométricas de peso y talla. Se calculó el Índice de Masa Corporal (IMC). La coordinación motora (CM) se evaluó utilizando la batería de Körperkoordinationstest Für Kinder (KTK). Los resultados mostraron que en las mujeres el grupo Normopeso tenía un mejor desempeño en la transposición lateral que los grupos Sobrepeso y Obesidad (p˂0.05). En los hombres, el grupo Normopeso superó al grupo Obesidad en los saltos monopedales (p˂0.05). Además, al analizar las diferencias entre sexos, se determinó que las mujeres registraron mayor puntaje que los hombres en el equilibrio a la retaguardia (p<0.05), por su parte, los hombres registraron mejores rendimientos en saltos laterales, transposición lateral y el puntaje total del KTK (p<0.05). Se concluye que existe menor índice de CM en los escolares con elevado IMC, y que existen diferencias significativas entre hombres y mujeres en el equilibrio, saltos laterales, transposición lateral y el puntaje total del test KTK.

The objective of this research was to analyze the relationship between motor coordination (CM) and Body Mass Index in Chilean schoolchildren between 7 and 9 years of age. The study was observational cross-sectional, correlational and descriptive study. 180 students of both sexes were evaluated (90 women aged 8.4 ± 0.9 years and 90 men aged 8.5 ± 0.9 years). Anthropometric weight and height variables were measured and the Body Mass Index (BMI) was calculated. The CM was evaluated using the battery of Körperkoordinationstest Für Kinder (KTK). The results showed that in the lateral transposition, the normal weight group outperforms the overweight and Obesity group (p˂0.05) for women. For men, in monopedal jumps, the normal weight group also outperformed the obesity group (p˂0.05). In addition, when analyzing the differences between the sexes, it was noted that women had a higher score than men in the rear balance (p˂0.05). On the other hand, men had performed better in lateral jumps, lateral transposition and the total KTK score (p˂0.05). In conclusion, the study found that there was a lower CM index in schoolchildren with a high BMI, and that there were significant differences between men and women in terms of balance, lateral jumps, lateral transposition, and the total score of the KTK test.

O objetivo da pesquisa foi analisar a relação entre a coordenação motora (CM) com o Índice de Massa Corporal corporal em escolares chilenos entre 7 e 9 anos de idade. O estudo foi observacional transversal, com características descritivas e correlacionais. Foram avaliados 180 escolares de ambos os sexos (90 mulheres com idade de 8,4 ± 0,9 anos e 90 homens com idade de 8,5 ± 0,9 anos). Variáveis antropométricas de peso e altura foram medidas. O Índice de Massa Corporal (IMC) foi calculado. Além disso, a coordenação motora (MC) foi avaliada por meio da bateria Körperkoordinationstest Für Kinder (KTK). Os resultados mostraram que, para mulheres em transposição lateral, o grupo Peso Normal supera o grupo Sobrepeso e Obeso (p˂0,05). Para os homens, nos saltos monopedais o grupo Peso Normal supera o grupo Obesidade (p˂0,05). Além disso, ao analisar as diferenças entre os sexos, percebe-se que as mulheres apresentam pontuação maiores que os homens no equilíbrio de retaguarda (p<0,05), enquanto os homens apresentam melhor desempenho nos saltos laterais, transposição lateral e pontuação total KTK (p< 0,05). Conclui-se que há menor índice de CM em alunos com IMC elevado, e que existem diferenças significativas entre homens e mulheres para equilíbrio, saltos laterais, transposição lateral e pontuação total do teste KTK.

Relación entre Índices Antropométricos de Obesidad y Condición Física en Escolares de 9 a 14 Años de la Región de Valparaíso, Chile / Relationship Between Anthropometric Indices of Obesity and Physical Condition in Schoolchildren Aged 9 to 14 Years From the Valparaíso Region, Chile

Los objetivos de este estudio fueron 1) describir factores antropométricos asociados a la obesidad y pruebas de condición física junto con 2) determinar la correlación entre estas variables en un grupo de escolares provenientes de la región de Valparaíso. Participaron un total de 109 escolares divididos por sexo y por grupos de edad. Los escolares fueron divididos en dos grupos entre 9 a 11 años (24 hombres= 47,98 ± 10,4 kg; 145,73 ± 7,3 cm; 25 mujeres= 45,06 ± 11,1 kg; 145,30 ± 6,6 cm) y entre 12 a 14 años (24 hombres= 54,85 ± 13,2 kg; 158,42 ± 8,8 cm; 36 mujeres= 52,21 ± 9,1 kg; 155,36 ± 6,1 cm). Se realizaron evaluaciones de la condición física utilizadas en el proceso de evaluación del Sistema de Medición de la Calidad de la Educación (SIMCE) de educación física para escolares chilenos. Estas evaluaciones incluyeron parámetros de flexibilidad, carrera, salto horizontal, y resistencia muscular. Junto con esto, se evaluaron variables antropométricas como peso, estatura y perímetro de cintura para establecer índices antropométricos de obesidad como el índice de masa corporal (IMC), el perímetro de cintura (PC) y el índice de cintura estatura (ICE). Se encontraron diferencias significativas entre los grupos de hombres de los diferentes grupos de edad en las pruebas de condición física, resistencia muscular abdominal (p = 0,001), salto horizontal (p = 0,002) y prueba de carrera (p = 0,003). Entre los grupos de mujeres se encontraron diferencias significativas en las variables de condición física, salto horizontal (p = 0,002) y carrera (p = 0,003). Tanto en hombres como en mujeres del grupo de 9 a 11 años se encontraron correlaciones significativas entre las variables antropométricas con pruebas de salto horizontal y capacidad de carrera (p = 0,03, r = -0,42 - 0,83, moderado a muy fuerte). En este mismo grupo solo las mujeres presentaron una correlación significativa entre parámetros antropométricos y la prueba de resistencia muscular en flexo extensiones de codo (p < 0,05, r = -0,42 - -0,52, moderado a fuerte) y abdominales (p < 0,05, r = -0,57 - -0,60, fuerte). Para el grupo entre 12 y 14 años se obtuvieron correlaciones negativas entre el ICE y la prueba de carrera en hombres (p < 0,016, r = -0,48, moderado), PC y la prueba de carrera en mujeres (p < 0,011, r = -0,41, moderado). Sólo en mujeres fue posible encontrar correlaciones significativas entre PC, IMC e ICE con salto horizontal (p < 0,05, r = 0,38 - 0,48, moderado). Los resultados sugieren una correlación negativa entre parámetros antropométricos de exceso de peso corporal y el rendimiento en pruebas físicas, siendo en el grupo de mayor edad las mujeres quienes presentan mayor cantidad de correlaciones significativas entre variables. Estos datos refuerzan la importancia de incluir abordajes integrales en las clases de educación física considerando estilos de vida activos y saludables en conjunto con la promoción de la actividad física.

SUMMARY: The objectives of this study were 1) to describe anthropometric factors associated with obesity and physical fitness tests and 2) to determine the correlation between these variables in a group of schoolchildren from the Valparaíso region. A total of 109 schoolchildren divided by sex and age groups participated. The schoolchildren were divided into two groups between 9 to 11 years (24 males = 47,98 ± 10,4 kg; 145,73 ± 7,3 cm; 25 females = 45,06 ± 11,1 kg; 145,30 ± 6,6 cm) and between 12 to 14 years (24 males = 54,85 ± 13,2 kg; 158,42 ± 8,8 cm; 36 females = 52,21 ± 9,1 kg; 155,36 ± 6,1 cm). Physical fitness assessments used by the Sistema de Medición de la Calidad de la Educación (SIMCE) evaluation process for physical education for Chilean schoolchildren were performed. These assessments included flexibility, sprint capacity, horizontal jump, and muscular endurance parameters. In addition, anthropometric variables such as weight, height and waist circumference were evaluated to establish anthropometric indices of obesity such as body mass index (BMI), waist circumference (WC) and waist-height index (WHI). Significant differences were found between the groups of men in the different age groups in the physical fitness tests, abdominal muscular endurance (p = 0.001), horizontal jump (p = 0.002), sprint test (p = 0.003) and the anthropometric index BMI (p = 0.048). Among the female groups, significant differences were only found in the physical condition variables, horizontal jump (p = 0.002) and sprint (p = 0.003). In both males and females in the 9- to 11- year-old group, significant correlations were found between anthropometric variables and tests of horizontal jumping and sprint ability (p = 0.03, r = -0.42 - 0.83, moderate to very high). In this same group, only females presented a significant correlation between anthropometric parameters and muscular endurance tests in elbow flexion (p < 0.05, r = -0.42 - -0.52, moderate to high) and abdominals (p < 0.05, r = -0.57 - -0.60, high). For the group between 12 and 14 years, negative correlations were obtained between WHI and the sprint test in males (p < 0.016, r = -0.48, moderate), WC and the sprint test in females (p < 0.011, r = -0.41, moderate). Only in women was it possible to find significant correlations between WC, BMI and ICE with a horizontal jump (p < 0.05, r = 0.38 - 0.48, moderate). The results suggest a negative correlation between anthropometric parameters of excess body weight and performance on physical tests, with women in the older age group presenting the highest number of significant correlations between variables. These data reinforce the importance of including integral approaches in physical education classes that consider active and healthy lifestyles together with the promotion of physical activity.

Desperdicio de alimentos en comedores escolares de una región de la zona centro sur de Chile: Percepciones de manipuladoras de alimentos del Programa de Alimentación Escolar

Introducción: Los desperdicios de alimentos en los comedores escolares son un problema que afecta al uso de recursos naturales, humanos y económicos. Objetivo: Identificar las opiniones y percepciones de manipuladoras de alimentos sobre factores relacionados al desperdicio de alimentos y posibles estrategias para disminuirlo en comedores escolares del Programa de Alimentación Escolar de la Junta Nacional de Auxilio Escolar y Becas en Chile. Métodos: Diseño cualitativo mediante técnica de grupos focales, con 33 participantes. Se aplicó un protocolo de investigación cualitativo que incluyó consentimiento informado, caracterización sociodemográfica, pauta de observación y guion con las dimensiones exploradas. Cada grupo contó con moderador experto y un observador. Se grabó y transcribió el audio de cada sesión y se analizó mediante ATLAS. Ti, versión 8. Resultados: Según las manipuladoras, los alimentos menos consumidos por los estudiantes son las legumbres, verduras frescas, productos marinos y algunas salsas. Estiman que el desperdicio de alimentos oscila entre los 25 a 100 Kilos al día. Las mujeres identifican factores claves en el rechazo de los alimentos por parte de los escolares; estética, olor y sabor del plato; repetitividad del menú; y aspectos culturales. Como estrategias para reducir el desperdicio proponen variar el menú, incorporar alimentos conocidos por los escolares, educar a los padres en la importancia de ofrecer alimentos y preparaciones saludables y sostenibles; fomentar la participación de toda la comunidad educativa en el proceso alimentario. Conclusiones: El estudio reveló que el desperdicio de alimentos en los comedores escolares es un problema complejo que requiere una intervención multidimensional que involucre a todos los actores del sistema alimentario escolar.

Introduction: Food waste in school canteens is a problem that affects the use of natural, human and economic resources. Objective: Identify the opinions and perceptions of food handlers about food waste factors and possible strategies to reduce them in school canteens of the School Feeding Programme of the Junta Nacional de Auxilio Escolar y Becas in Chile. Methods: Qualitative design using a focus group technique with 33 participants. A qualitative research protocol that included informed consent, sociodemographic characterisation, observation guidelines, and a script with the dimensions explored was applied. Each group had an expert moderator and an observer. The audio of each session was recorded, transcribed, and analysed using ATLAS. Ti, version 8. Results: According to the handlers, the foods least consumed by the students are legumes, fresh vegetables, seafood, and some sauces. They estimate that food waste ranges from 25 to 100 kg per day. Women identify critical factors in the rejection of food by schoolchildren: aesthetics, smell, and taste of the dish; repetitiveness of the menu; and cultural aspects. As strategies to reduce waste, they propose varying the menu, incorporating foods familiar to schoolchildren, educating parents about the importance of offering healthy and sustainable food and preparations, and encouraging the participation of the entire educational community in the food process. Conclusions: The study revealed that food waste in school canteens is a complex problem that requires a multidimensional intervention that involves all actors in the school food system.

[Nutritional factors related to insulin resistance in children and adolescents]. / Factores nutricionales relacionados con la resistencia a la insulina en escolares y adolescentes.

Introduction: Insulin resistance is described as a defect in the binding of insulin to its receptor and is associated with several diseases, including obesity and type 2 diabetes. Insulin resistance has been linked to vitamin and mineral deficiencies, especially those involved in oxidative stress. The Mediterranean diet, a diet based on the Healthy Eating Index or the Dietary Approaches to Stop Hypertension (DASH) diet are dietary patterns that have been associated with a lower risk of developing insulin resistance in children. Therefore, a diet rich in antioxidant vitamins and minerals, fiber, calcium, and polyunsaturated fatty acids and low in free sugars, sodium and saturated fatty acids may decrease the risk of insulin resistance in this age group. In addition, other nutritional factors, such as avoiding fast food, eating dinner with the family, not eating while watching TV or eating a sufficient and healthy breakfast on a regular basis seem to be associated with a lower risk of insulin resistance. Therefore, it is important to establish balanced daily eating habits to prevent and treat insulin resistance in schoolchildren and adolescents.

Introducción: La resistencia a la insulina se explica como un defecto en la unión de la insulina con su receptor y está asociada con numerosas enfermedades, como la obesidad o la diabetes tipo 2, entre otras. La resistencia a la insulina se ha relacionado con la deficiencia de vitaminas y minerales, especialmente de aquellos involucrados en el estrés oxidativo. La dieta mediterránea, una dieta basada en el Healthy Eating Index o la dieta Dietary Approaches to Stop Hypertension (DASH) son patrones dietéticos que se han asociado con un menor riesgo de presentar resistencia a la insulina en edad infantil. Por tanto, una dieta rica en vitaminas y minerales antioxidantes, fibra, calcio y ácidos grasos poliinsaturados y baja en azucares libres, sodio y ácidos grasos saturados puede disminuir el riesgo de presentar resistencia a la insulina en este grupo de edad. Además, otros factores nutricionales, como evitar la comida rápida, cenar en familia, no comer mientras se ve la televisión o el consumo regular de un desayuno suficiente y saludable son hábitos que parecen estar relacionados con menor riesgo de presentar resistencia a la insulina. Por tanto, es importante establecer hábitos alimentarios diarios equilibrados para prevenir y tratar la resistencia a la insulina en escolares y adolescentes.

Se colectaron y analizaron el peso, talla y circunferencia de cintura de escolares del noroeste de México pre y post pandemia por COVID 19 (n=479 y n=820). Además, se analizaron los cambios en la alimentación en una submuestra de 203 y 179 escolares pre y post pandemia, respectivamente. Resultados. La edad promedio de los escolares en 2019 fue 8,9 ±1,75 y en el 2022 de 9,1 ± 1,54 años. Se observó un aumento de 6,2 puntos porcentuales en la prevalencia de sobrepeso y obesidad y diferencias en la distribución de las categorías del estado nutricio (p=0,049) entre los dos periodos. También, se observaron cambios en la adiposidad central con un aumento de 3 centímetros en la circunferencia de cintura (p=0,001; 62,6 y 65,6 cm). El índice de alimentación saludable (IAS) mostró una alimentación poco saludable durante los dos periodos. Conclusiones. El aumento en las prevalencias de sobrepeso y obesidad, así como de obesidad central durante la emergencia epidemiológica, indicaron un deterioro del estado nutricio de los escolares, que coincide con los reportes en poblaciones a nivel mundial y en Latinoamérica; los resultados resultan preocupantes dada la problemática antes de la emergencia(AU)

Introduction. Negative health consequences due to social isolation during the COVID-19 pandemic were observed worldwide; overweight and obesity showed increasing trends. Objective. To analyze the changes in overweight, obesity and diet of schoolchildren in northwest Mexico before and after lockdown due to COVID-19. Materials and methods. Weight, height, and waist circumference of schoolchildren (n=479 pre-pandemic and n=820 post-pandemic) were collected in public schools located in medium to high marginalization neighborhoods. In the same periods dietary data was collected from a subsample of 203 and 179 schoolchildren, respectively. Results. The average age of schoolchildren in 2019 was 8,9 ±1,75 and 9,1 ± 1,54 in 2022. An increase in percentage of 6,2 was observed in the overweight plus obesity prevalence and a significant difference in the distribution of nutritional status (p=0,049) between the two periods. In addition, changes in central adiposity were observed, with an increase of 3 centimeters in waist circumference (p=0,001; 62,6 and 65,6 cm). The healthy eating index (HAI) classified the diet of schoolchildren as unhealthy during both periods. Conclusions. The increase in the prevalence of overweight and obesity, as well as central adiposity is worrying given that they were already a health problem before the COVID 19 confinement(AU)

Introducción. En los refrigerios escolares se ha incrementado el consumo de los productos industrializados y se ha observado una disminución en la ingesta de alimentos frescos. Objetivo. Determinar la prevalencia y tendencia de sobrepeso, obesidad y consumo de alimentos no recomendables en escolares del norte de México. Materiales y métodos. Estudio descriptivo y transversal, realizado del año 2015 a 2022 en una muestra de 468 niños de ambos sexos de 9 a 12 años de escuelas públicas, se les realizó mediciones antropométricas de peso, estatura y circunferencia de cintura. Para diagnosticar el estado nutricional se utilizó el puntaje Z del índice de masa corporal (IMC) por medio del software Anthro Plus. El consumo alimentario de los escolares se evaluó por medio de una lista de cotejo durante cinco días consecutivos por observación directa los alimentos y bebidas que los escolares llevaron de casa para consumir durante el horario escolar. Resultados. Se encontró que el sobrepeso (SBP) y la obesidad (OB) aumentó durante la pandemia, siendo mayor el SBP en las niñas (17,0%) y mayor la OB en los niños (46,8%). En cuanto a la ingesta alimentaria se observó que durante la pandemia aumentó el consumo de alimentos no recomendables asociándose con el IMC. Conclusiones. El sobrepeso y la obesidad aumentó durante la pandemia, siendo mayor el sobrepeso en las niñas y mayor la obesidad en los niños. En cuanto a la ingesta alimentaria se observó que durante la pandemia el consumo de alimentos no recomendables específicamente en las bebidas azucaradas aumentó y se asoció con el IMC(AU)

Introduction. School snacks have increased consumption of industrialized products and a decrease in the intake of fresh food has been observed. Objective. Determine the prevalence and trend of overweight, obesity and consumption of undesirable foods in schoolchildren in northern Mexico. Materials and methods. A descriptive and cross-sectional study was conducted in a sample of 468 children of both sexes aged 9 to 12 in public schools and anthropometric measurements of weight, height and waist circumference were made. The body mass index (BMI) Z score was used to diagnose nutritional status using the Anthro Plus software. Food consumption of schoolchildren was evaluated by means of a checklist for five consecutive days by direct observation of the food and beverages that schoolchildren took from home to consume during school hours. Results. Overweight (PBS) and obesity (OB) were found to increase during the pandemic, with higher PBS in girls (17.0%) and higher OB in boys (46.8%). About food intake, it was observed that during the pandemic consumption of undesirable foods increased in association with the BMI. Conclusions. Overweight and obesity increased during the pandemic, being more overweight in girls and obesity in boys. As for food intake it was noted that during the pandemic consumption of foods not specifically recommended in sugary drinks increased and was associated with BMI(AU)

Measuring categorisation in pre-school children: new toolkit, new insights

Introduction: whilst recent years have witnessed considerable research into infant categorisation, its development during the pre-school period has garnered far less interest and innovation. Objective: this paper documents the development of a valid and reliable new toolkit for measuring categorisation in children, designed to allow fine-grained differentiation through four short tasks. Methods: the paper outlines how a pilot study with 55 children reduced confounding variables, ruled out several explanations for performance variations and enabled procedural refinements. It then documents a study conducted with 190 children aged 30-60 months. Results: this more sophisticated testing mechanism challenges previously accepted developmental norms and suggests both sex and socio-economic status (and their interaction) influence categorisational abilities in pre-schoolers. Conclusion: the results indicate that preschool children's ability to categorise varies markedly, with implications for their capacity to access formal education.

Introdução: embora nos últimos anos tenha havido pesquisas consideráveis sobre a categorização infantil, seu desenvolvimento durante o período pré-escolar atraiu muito menos interesse e inovação. Objetivo: este artigo documenta o desenvolvimento de um novo kit de ferramentas válido e confiável para medir a categorização em crianças, projetado para permitir diferenciação refinada por meio de quatro tarefas curtas. Método: o artigo descreve como um estudo piloto com 55 crianças reduziu variáveis de confusão, descartou várias explicações para variações de desempenho e permitiu refinamentos de procedimentos. Em seguida, documenta um estudo realizado com 190 crianças de 30 a 60 meses. Resultados: este mecanismo de teste mais sofisticado desafia as normas de desenvolvimento previamente aceitas e sugere que o sexo e o status socioeconômico (e sua interação) influenciam as habilidades de categorização em pré-escolares. Conclusão: os resultados indicam que a capacidade de categorização dos pré-escolares varia acentuadamente, com implicações na sua capacidade de acesso à educação forma

[Do socioeconomic determinants influence school menus?] / ¿Influyen los determinantes socioeconómicos en la oferta de los menús escolares?

Introduction: Introduction: the components of school menus is an important area in health strategies. Objectives: the aim of this study was to analyse differences in adherence to recommended food frequencies and other characteristics of school meals in educational centres according to the type of school and neighbourhood income. Method: schools in the city of Barcelona with a lunch service were offered a three-year review. In the three academic years, 341 schools participated: 175 were public and 165 were private. To identify any differences, the Pearson Chi-squared test or Fisher exact test were used, as appropriate. Statistical analyses were performed with the STATA SE/15 programme. Results: no statistically significant differences were found by the socioeconomic level of the school neighbourhood. Private and subsidised schools showed lower adherence to recommendations on pasta (11.1 %), red and processed meat (24.7 %), total meat (7.4 %) and fresh fruit (12.1 %), and lower use of the recommended cooking oil (13.1 %). In contrast, public schools showed lower adherence to the recommended type of frying oil (16.9 %). Conclusions: in private and subsidised schools, improvements should be recommended on the frequency of intake of certain foods. Future studies should examine the causes of lower adherence to certain recommendations in these centres.

Introducción: Introducción: la oferta de menús escolares es un área relevante en las estrategias de salud. Objetivos: analizar las diferencias en el cumplimiento de las frecuencias recomendadas de alimentos y otras características del comedor escolar en los centros educativos según su titularidad y la renta del barrio. Métodos: se ofreció la revisión trienal a los centros escolares de la ciudad de Barcelona que disponían de servicio de comedor. En los tres cursos académicos, participaron 341 centros: 175 públicos y 165 de titularidad privada. Para observar si existían diferencias, se utilizó la prueba de Pearson Chi-cuadrado o el test exacto de Fisher según el caso. Los análisis se realizaron con el programa estadístico STATA SE/15. Resultados: no se encontraron diferencias significativas según el nivel socioeconómico del barrio del centro educativo. Los centros educativos privados y concertados presentaban un menor cumplimiento en la pasta (11,1 %), las carnes rojas y procesadas (24,7 %), la carne total (7,4 %) y la fruta fresca (12,1 %), así como un menor uso del aceite recomendado para cocinar (13,1 %). Por el contrario, en los centros educativos públicos se observaba un menor cumplimiento en la recomendación del tipo de aceite para freír (16,9 %). Conclusiones: en los centros privados y concertados es necesario recomendar mejoras en la adecuación de las raciones. Se debería indagar en las causas que pueden explicar esta menor adecuación en varios aspectos como en el cumplimiento de las adecuaciones en estos centros.

[Food quality in pre-school and school children in Chile during the COVID-19 pandemic]. / Calidad de la alimentación en preescolares y escolares en Chile durante la pandemia de COVID-19.

Introduction: Introduction: the COVID-19 pandemic can affect the quality of food and nutrition of preschoolers and schoolchildren through an increase in food insecurity of families, by measures such as confinement and closure of educational establishments, which affects the daily structure, feeding schedules, and quality of food. Objectives: analyze the overall food quality of preschool and school children in Chile during the COVID-19 pandemic. Methods: five hundred and fifty-one schoolchildren (22.5 % boys and 77.5 % girls) from five Chilean cities distributed in northern, central, and southern macro zones participated in a convenience sampling. The Global Food Quality Index was applied. The data were analyzed in the IBM SPSSV24 statistical program. Differences in proportions were analyzed employing crossed tables. Results: schoolchildren from rural areas presented lower eating quality than their urban peers (p = .005). Schoolchildren who eat with the whole family had better indicators of eating quality than those who ate alone (p = .002). In nine out of 12 dietary components, evaluated females present higher compliance with dietary recommendations. Conclusions: further research is needed on changes in dietary intake and dietary quality of children and their families during the pandemic. This will allow us to analyze the impact of the pandemic on eating behavior and its possible consequences.

Introducción: Introducción: La pandemia por COVID-19 puede afectar en la calidad de la alimentación y la nutrición de preescolares y escolares a través de un incremento de la inseguridad alimentaria de las familias, por medidas como el confinamiento y cierre de establecimientos educacionales, lo que afecta la estructura diaria, horarios de alimentación y calidad de la alimentación. Objetivo: analizar la calidad global de la alimentación de preescolares y escolares en Chile durante la pandemia de COVID-19. Métodos: en un muestreo por conveniencia participaron 551 escolares (22,5 % niños y 77,5 % niñas) de cinco ciudades de Chile distribuidas en macrozonas norte, centro y sur. Se aplicó el índice de calidad global de la alimentación. Los datos fueron analizados en el programa estadístico IBM SPSSV24. Se analizaron diferencias de proporciones a través de tablas cruzadas. Resultados: escolares de zonas rurales presentaron menor calidad de la alimentación que pares de zonas urbanas (p = ,005). Escolares que comen con toda la familia presentan mejores indicadores de calidad de la alimentación que aquellos que lo hacen solos (p = ,002). En nueve de 12 componentes de la alimentación evaluados, las mujeres presentan mayor cumplimiento de recomendaciones alimentarias. Conclusiones: se requieren más investigaciones sobre los cambios de ingesta dietética y calidad de la alimentación de los niños y niñas y sus familias durante la pandemia. Esto permitirá analizar el impacto de la pandemia en la conducta alimentaria y sus posibles consecuencias.

Catecismos matemáticos en los Estados Unidos de Colombia (1863-1886)

El ideal educativo en los Estados Unidos de Colombia (1863-1886) fue implantar las innovaciones de los pedagogos europeos del momento: Pestalozzi, Froebel y Herbart, según los cuales el aprendizaje se lograba con la experimentación y el contacto con la naturaleza. La escuela primaria enseñaba el dominio del idioma para la lectura y la escritura; la matemática proporcionaba el conocimiento de las operaciones con números, para resolver problemas prácticos de la vida cotidiana y las actividades comerciales con el dominio de lo referente a pesas y medidas. Teniendo en cuenta estos motivos puede decirse que los catecismos matemáticos se adaptaron a estos requerimientos en lo que respecta a la temática.

The educational ideal in the United States of Colombia was to implement the innovations of the European pedagogues of the time: Pestalozzi, Froebel, and Herbart, according to whom learning was achieved through experimentation and contact with nature. The elementary school taught the mastery of language for reading and writing; mathematics provided the knowledge of operations with numbers, to solve daily-life practical problems and commercial activities with the mastery of weights and measures. By taking these reasons into account, it can be said that mathematical catechisms were adapted to these requirements in terms of the subject matter.

Conhecimento, atitudes e práticas em primeiros socorros no ambiente escolar: uma revisão integrativa / Knowledge, attitudes and practices in first rescue in the school environment: an integrative review / Conocimientos, actitudes y prácticas de primeros auxilios en el entorno escolar: una revisión integradora

Conclusão: Constata-se que há desconhecimento sobre as ações necessárias no atendimento em primeiros socorros, o que impacta nas atitudes e práticas executadas, bem como no tratamento e prognóstico. Assim, intervenções educativas são estratégias que promovem o desenvolvimento de conhecimento, atitudes e práticas necessárias ao atendimento em primeiros socorros

Conclusion: It was observed that there is a lack of knowledge about the necessary actions in first aid care, which impacts the attitudes and practices performed, as well as the treatment and prognosis. Thus, educational interventions are strategies that promote the development of knowledge, attitudes and practices necessary for first aid

Conclusión: Se observó que existe un desconocimiento sobre las acciones necesarias en la atención de primeros auxilios, lo que repercute en las actitudes y prácticas realizadas, así como en el tratamiento y pronóstico. Así pues, las intervenciones educativas son estrategias que promueven el desarrollo de los conocimientos, las actitudes y las prácticas necesarias para la atención de primeros auxilios

Intergenerational associations of adverse and positive maternal childhood experiences with young children's psychosocial well-being.

Background: Maternal adverse childhood experiences (ACEs) are believed to have negative consequences on offspring health. However, positive childhood experiences (PCEs) may be concurrent with ACEs, and little is known about how ACEs and PCEs transmit intergenerationally in the context of each other.Objective: To explore the independent effect of maternal ACEs and PCEs on offspring psychosocial well-being and how ACEs and PCEs are intergenerationally transmitted in their context.Method: Data were 2587 mother-child dyads in Anhui provinces of China. Mothers retrospectively reported their ACEs and PCEs, as well as provided demographic characteristics and their children's psychosocial well-being. Logistic regression models were performed to explore the associations of maternal ACEs and PCEs with offspring psychosocial well-being.Results: Separate unadjusted logistic regression models showed that children with mothers reported high ACEs scores were more likely to have psychosocial challenges (total difficulties and prosocial problems), while children whose mothers reported high PCEs scores were less likely to have psychosocial challenges. When we added maternal ACEs and PCEs to a same model, we found that PCEs slightly neutralised the negative effects of ACEs on offspring's total difficulties and prosocial problems. When stratified by sample, mothers with high PCE scores and higher maternal ACEs were related with a higher risk of offspring total difficulties; mothers with low levels of ACEs and high PCEs tend to report a lower risk of offspring total difficulties.Conclusions: Results suggest that PCEs are positively and intergenerationally transmitted. Results suggest that PCEs are positively and intergenerationally transmitted. More programme should be provided to increase maternal PCEs. When preventing the intergenerational transmission of ACEs, specific interventions should be provided to mothers with different levels of PCEs.

Positive childhood experiences positively transmit intergenerationally.Stronger relationship between maternal ACEs and risk of offspring total difficulties was observed among mothers with above-average positive childhood experiences scores.A stronger relationship between maternal PCEs and fewer offspring total difficulties was observed among mothers with low adverse maternal childhood experiences scores.

Correlation of body mass index and waist to height ratio with cardiovascular risk factors in Colombian preschool and school children

Objective: To analyze the agreement between body mass index (BMI) and waist-to-height Ratio (WHtR) to identify preschool and school children with cardiovascular risk factors (CRFs). Methods: Three-hundred-twenty-one kids were divided into preschool (3-5 years) and school children (6-10 years). BMI was used to classify children as overweight or obese. Abdominal obesity was defined with a WHtR ≥0.50. Fasting blood lipids, glucose and insulin were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. The presence of CRFs and multiple non-waist circumference (non-WC) metabolic syndrome factors (MetS-Factors) [high HOMA-IR, high triglycerides and low high-density lipoprotein cholesterol (HDL-C)] were analyzed. Results: One-hundred-twelve preschool and 209 school children were evaluated. WHtR ≥0.50 classified abdominal obesity in more than half of the preschool children, exceeding those classified with overweight+obesity by BMI (59.5% vs. 9.8%; p0.05). There were similar proportions of school children classified with abdominal obesity by the WHtR and overweight+obesity by the BMI (18.7% vs. 24.9%; p>0.05). There was substantial agreement between WHtR and BMI to identify school children with high total cholesterol values, low-density lipoprotein cholesterol (LDL-C), triglycerides, non-HDL-C, insulin, HOMA-IR, low HDL-C values, and the presence of multiple non-WC MetS-Factors (kappa: 0.616 to 0.857, p<0.001). Conclusion: In preschool children WHtR ≥0.5 disagree with BMI results, but in school kids, it has good agreement with the BMI to classify the children´s nutritional status and to identify those with CRFs.

Objetivo: Analizar el grado de acuerdo entre el índice de masa corporal (IMC) y la relación/cintura estatura (rCE) para identificar niños con factores de riesgo cardiovascular (FRC). Métodos: Estudio transversal analítico con 112 niños preescolares (3-5 años) y 209 escolares (6-10 años). El sobrepeso y la obesidad se clasificaron con el IMC y la obesidad abdominal con la rCE ≥0.50. Se tomaron muestras sanguíneas en ayuno para análisis de glucosa, insulina, lípidos y cálculo del índice HOMA-IR. Se analizó la presencia de FRC y de múltiples factores del síndrome metabólico (Factores-SinMet) diferentes a la cintura [HOMA-IR elevado, triglicéridos elevados y colesterol de alta densidad (HDL-C) bajo]. Resultados: rCE ≥0.50 clasificó con obesidad abdominal a más de la mitad de los niños preescolares, excediendo el número de niños clasificados con sobrepeso+obesidad por IMC (59.5% vs 9.8%; p0.05). Fueron similares las proporciones de niños escolares clasificados con obesidad abdominal por la rCE o con sobrepeso+obesidad por el IMC (18.7% vs. 24.9%; p>0.05). Hubo acuerdo sustancial entre la rCE y el IMC para identificar niños escolares con valores elevados de colesterol total, colesterol de baja densidad, triglicéridos, colesterol no-HDL, insulina, HOMA-IR, valores bajos de HDL-C y la presencia de múltiples Factores-SinMet diferentes a la cintura (kappa: 0.616 a 0.857, p<0.001). Conclusión: En niños preescolares la aplicación de rCE ≥0.5 no presenta acuerdo con el IMC, pero en escolares presenta un acuerdo sustancial con el IMC en la clasificación del estado nutricional y en la identificación de niños con FRC.
