Changes in Height and Body Weight Within a Time Period of 35 Years in Males of the Same Age / Cambios en la Altura y el Peso Corporal en un Período de 35 Años en Hombres de la Misma Edad

SUMMARY: Height and body weight measurements are among the most important anthropometric variables when assessing a population's growth, development and body composition. This study aimed to evaluate the height and body weight variability of male entities aged 17-18 years within 35 years. This goal was realized by comparing the height and body weight of the population of the same gender and age in three different time studies. The descriptive statistical parameters and T-test for independent groups show systematic and significant differences in measured variables between three measurements in different timelines. Both in body height and body weight, from measurement to measurement, significant systematic and statistically significant differences (p<0.01) have been identified (1985: BH= 172.8cm, BW= 61.7kg; 2004: BH=176.8 cm, BW=66.9 kg; 2019: BH=178.5 cm, BW=72 kg). The results of this study prove that the change in the socio-economic status of a population over a period time of 35 years can significantly affect the growth and development of children/adolescents.

Las medidas de altura y peso corporal se encuentran entre las variables antropométricas más importantes a la hora de evaluar el crecimiento, el desarrollo y la composición corporal de una población. Este estudio tuvo como objetivo evaluar la variabilidad de la altura y el peso corporal de entidades masculinas de 17 a 18 años dentro de 35 años. Este objetivo se logró comparando la altura y el peso corporal de la población del mismo sexo y edad en tres estudios temporales diferentes. Los parámetros estadísticos descriptivos y la prueba T para grupos independientes muestran diferencias sistemáticas y significativas en las variables medidas entre tres mediciones en diferentes líneas de tiempo. Tanto en la altura como en el peso corporal, de medición en medición, se han identificado diferencias significativas sistemáticas y estadísticamente significativas (p<0,01) (1985: BH= 172,8 cm, BW= 61,7 kg; 2004: BH=176,8 cm, BW=66,9 kg; 2019: BH=178,5 cm, BW=72 kg). Los resultados de este estudio demuestran que el cambio en el estatus socioeconómico de una población durante un período de 35 años puede afectar significativamente el crecimiento y desarrollo de niños/ adolescentes.

Association between telomere length in the DNA of peripheral blood leukocytes and the propofol dose in anesthesia induction: an observational study

Abstract Introduction: Propofol is a widely used anesthetic and its dose is closely related to aging. Telomere length (TL) is a unique heritable trait, and emerging as a biomarker of aging, health and disease. Telomerase RNA component (TERC) plays an important role in maintaining TL. We proposed a hypothesis that propofol dose in general anesthesia can be predicted by measuring TL before operation, which greatly reduced the risk of anesthesia, especially the elderly. Methods: The association between the propofol dose in anesthesia induction and: TL in the DNA of peripheral blood leukocytes; body weight; sex; difference of the Bispectral Index (BIS) before and after anesthesia induction in patients was evaluated by multivariable linear regression analyses. The mutation at the 5'end or 3'end of TERC was detected. We recruited 100 patients of elective surgery. Results: We found that propofol dose in anesthesia induction was clearly correlated significantly with TL (r = 0.78, p < 0.001), body weight (r = 0.84, p = 0.004), sex (r = 0.83, p= 0.84, p = 0.004), sex (r = 0.83, p = 0.004), and difference of BIS before and after anesthesia induction (r = 0.85, p = 0.029). By comparing the absolute values of standardized regression coefficients (0.58, 0.21, 0.19, and 0.12) of the four variables, it can be seen that TL contributes the most to the propofol dose in anesthesia induction. However, the mutation at the 5' end or 3' end of TERC was not found. Conclusions: These findings provide preliminary evidence that the propofol dose in anesthesia induction was clearly correlated with genetically determined TL. TL may be a promising predictor of the propofol dose, which is beneficial to improve the safety of anesthesia and reduce perioperative complications.

Cardiovascular Fitness in Normal Weight and Obese Children and Adolescents - A Systematic Review of Studies Published After 2000s / Condición Cardiovascular en Niños y Adolescentes con Peso Normal y Obesos: Una Revisión Sistemática de Estudios Publicados Después de la Década del 2000

SUMMARY: The primary aim was to gather available data published after the 2000s, on cardiovascular fitness in normal weight and obese children and adolescents. Based on the data, the secondary aims were to identify the most used outcomes and to determine the differences in cardiovascular fitness in the mentioned populations. Following PRISMA recommendations, multiple databases were searched: Google Scholar, PubMed, Cochrane Library, ProQuest, and Research Gate, with additional inclusion criteria: original study published in English, normal weight and obese children and adolescents as participant sample, studies that have assessed cardiovascular fitness parameters, and studies with participant's nutrition state. A total of 19 studies, with a total of 4,988 included participants (both obese and normal weight) were identified, with the most common participants have presented better results in terms of BMI, BF%, VO2max, VO2peak and METs, while the HR values are inconsistently presented. Despite deficiencies the study deficiency in the last two decades, there are differences in the mentioned populations. Further studies should focus on including the technology that reaches teens and families for overweight and obesity prevention and advancements in standard measurements for juvenile overweight and obesity, as well as for the creation, adaption, and validation of measuring instruments. As good framework for future directions, there is a need for more concise and unified measurements of cardiovascular fitness parameters in normally weight and obese children and adolescents.

El objetivo principal fue recopilar datos disponibles publicados después de la década del 2000 sobre la condición cardiovascular en niños y adolescentes con peso normal y obesos. En base a estos datos, los objetivos secundarios fueron identificar los resultados más utilizados y determinar las diferencias en la condición cardiovascular en las poblaciones mencionadas. Siguiendo las recomendaciones de PRISMA, se realizaron búsquedas en múltiples bases de datos: Google Scholar, PubMed, Cochrane Library, ProQuest y Research Gate, con criterios de inclusión adicionales: estudio original publicado en inglés, niños y adolescentes con peso normal y obesidad como muestra participante, estudios que hayan evaluado enfermedades cardiovasculares, parámetros de condición física y estudios con el estado nutricional de los participantes. Se identificaron un total de 19 estudios, con un total de 4.988 participantes incluidos (tanto obesos como con peso normal), siendo las variables más comunes: IMC, %BF, VO2máx, VO2pico, FC, PAD, PAS y MET. Generalmente, los participantes con peso normal han presentado mejores resultados en términos de IMC, %BF, VO2máx, VO2peak y MET, mientras que los valores de FC se presentan de manera inconsistente. Independientemente de la deficiencia de estudios en las últimas dos décadas, existen diferencias en las poblaciones mencionadas. Estudios futuros deberían centrarse en incluir tecnología que llegue a adolescentes y familias para la prevención del sobrepeso y la obesidad y avances en las mediciones estándar del sobrepeso y la obesidad juvenil, así como para la creación, adaptación y validación de instrumentos de medición. Como buen marco para direcciones futuras, se necesitan mediciones más concisas y unificadas de los parámetros de la condición cardiovascular en niños y adolescentes con peso normal y obesos.

Liver Size and its Correlation with Anthropometric Parameters and Age / El Tamaño del Hígado y su Correlación con los Parámetros Antropométricos y la Edad

SUMMARY: The liver has over 500 physiological and biochemical roles in our organism so checking of liver size and function is a part of every clinical examination. Aim of our research was to estimate liver size on computed tomography (CT) of the abdomen images and to determinate relations between liver dimensions and anthropometric parameters. The research included 99 patients, 49 men and 50 women, who were referred for CT of abdomen. We measured body height (BH) and body mass (BM), and calculated body mass index (BMI) and body surface area (BSA). Also, on CT images we measured anteroposterior (AP), laterolateral (LL) and two craniocaudal liver diameters (one at the level of midclavicular line - CCmcl, and the other was maximal - CCmax). Liver volume (LV) was calculated with formula. Our results showed that AP diameter positively correlated with BSA (r=0.30) in women. LL diameter positively correlated with BH (r=0.43), and BSA (0.31) in men. CCmcl diameter positively correlated with BH (r=0.33), BM (r=0.31), and BSA (r=0.34) in men, while in women it correlated only with BH (r=0.38). CCmax diameter positively correlated with BH (r=0.33) and BSA (r=0.33) in men. LV positively correlated with BH and BSA in both men (r=0.36, r=0.33, respectively) and women (r=0.42, r=0.31, respectively), and in men also with BM (r=0.34). LL, CCmcl, CCmax, and LV negatively correlated with aging in both sexes After the age of 60, there was a decrease in size of LL, CC diameters, as well as in LV. We concluded that liver dimensions decrease with aging, regardless of sex at the expanse of LL and CC diameters which are related to the size of body parameters, so that for a precise evaluation of liver size all three diameters should be measured, LV as well as BH, BM, and BSA.

El hígado desempeña más de 500 funciones fisiológicas y bioquímicas en nuestro organismo, por lo que comprobar el tamaño y la función de este órgano es parte de cada examen clínico. El objetivo de nuestra investigación fue estimar el tamaño del hígado mediante tomografía computarizada (TC) de imágenes del abdomen y determinar las relaciones entre las dimensiones del hígado y los parámetros antropométricos. La investigación incluyó a 99 pacientes, 49 hombres y 50 mujeres, que fueron remitidos para TC de abdomen. Medimos la altura corporal (BH) y la masa corporal (BM), y calculamos el índice de masa corporal (IMC) y el área de superficie corporal (BSA). Además, en las imágenes de TC medimos los diámetros hepáticos anteroposterior (AP), laterolateral (LL) y dos craneocaudales (uno a nivel de la línea medioclavicular - CCmcl, y el diámetro máximo - CCmax). El volumen del hígado (VI) se calculó con una fórmula. Nuestros resultados mostraron que el diámetro AP se correlacionó positivamente con BSA (r = 0,30) en mujeres. El diámetro de LL se correlacionó positivamente con BH (r=0,43) y BSA (0,31) en hombres. El diámetro CCmcl se correlacionó positivamente con BH (r=0,33), BM (r=0,31) y BSA (r=0,34) en hombres, mientras que en mujeres se correlacionó solo con BH (r=0,38). El diámetro CCmax se correlacionó positivamente con BH (r=0,33) y BSA (r=0,33) en hombres. El VI se correlacionó positivamente con BH y BSA tanto en hombres (r=0,36, r=0,33, respectivamente) como en mujeres (r=0,42, r=0,31, respectivamente), y en hombres también con BM (r=0,34). LL, CCmcl, CCmax y LV se correlacionaron negativamente con el envejecimiento en ambos sexos. Después de los 60 años, hubo una disminución en el tamaño de los diámetros LL, CC y LV. Concluimos que las dimensiones del hígado disminuyen con la edad, independientemente del sexo, en la extensión de los diámetros LL y CC que están relacionados con el tamaño de los parámetros corporales, por lo que para una evaluación precisa del tamaño del hígado se debe medir LV como BH, BM y BSA.

Anthropometric Similarities and Differences in Children of Aymara and Non-Aymara Descent in Northern Chile: Implications for Health and Development / Similitudes y Diferencias Antropométricas en Niños de Etnia Aymara y Ascendencia No-Aymara en el Norte de Chile: Implicaciones para la Salud y el Desarrollo

SUMMARY: This study aims to assess the nutritional status of Aymara and non-Aymara children in Arica, comparing anthropometric measurements of boys and girls aged 4-10 to inform interventions for child health and development. We conducted a non-experimental, quantitative, cross-sectional study in Arica, Chile. The sample included 458 children, with equal representation of Aymara and non-Aymara children from diverse socioeconomic backgrounds. Trained research assistants collected anthropometric data using standardized techniques. IBM SPSS statistical software was used for data analysis, including Student's t-test and the Levene test. Both Aymara and non-Aymara children showed high prevalence of overweight and obesity. Boys had a meso-endomorph somatotype, while girls had an endomorph somatotype. Among 8-year-olds, non-Aymara children had a slightly higher mean body weight (35.87, SD 4.50) compared to Aymara children (32.27, SD 4.31), but the difference was not statistically significant (p>0.05). However, 10-year-old Aymara girls had a significantly higher mean body mass index (22.34, SD 4.21) than non-Aymara girls (20.10, SD 3.58) (p=0.05). Regarding body fat percentage, 10-year- old non-Aymara girls had a slightly higher mean (31.01, SD 5.64) than Aymara girls (26.12, SD 5.63), but the difference was not statistically significant (p>0.05). The study found high levels of overweight and obesity in children from northern Chile, increasing with age for both Aymara and non-Aymara groups. The somatotype patterns were consistent across both groups. Although the differences between Aymara and non-Aymara children were not statistically significant, the Aymara group showed slightly higher levels of overweight and obesity. Further research with a larger sample size is needed to confirm these results and identify potential trends. Efforts should focus on promoting healthy nutrition and physical activity to address the growing problem of overweight and obesity in this region.

Este estudio tiene como objetivo evaluar el estado nutricional de los niños Aymaras y no Aymaras en Arica, comparando las medidas antropométricas de niños y niñas de 4 a 10 años para informar las intervenciones para la salud y el desarrollo infantil. Realizamos un estudio no experimental, cuantitativo, de corte transversal en Arica, Chile. La muestra incluyó a 458 niños, con igual representación de niños Aymaras y no Aymaras de diversos estratos socioeconómicos. Asistentes de investigación capacitados recolectaron datos antropométricos utilizando técnicas estandarizadas. Se utilizó el software estadístico IBM SPSS para el análisis de datos, incluyendo la prueba t de Student y la prueba de Levene. Tanto los niños Aymaras como los no Aymaras presentaron una alta prevalencia de sobrepeso y obesidad. Los niños tenían un somatotipo meso-endomorfo, mientras que las niñas tenían un somatotipo endomorfo. Entre los niños de 8 años, los niños no Aymaras tenían un peso corporal medio ligeramente superior (35,87, DE 4,50) en comparación con los niños Aymaras (32,27, DE 4,31), pero la diferencia no fue estadísticamente significativa (p>0,05). Sin embargo, las niñas Aymaras de 10 años tenían un índice de masa corporal medio significativamente mayor (22,34, SD 4,21) que las niñas no Aymaras (20,10, SD 3,58) (p=0,05). En cuanto al porcentaje de grasa corporal, las niñas no Aymaras de 10 años tuvieron una media ligeramente superior (31,01, DE 5,64) que las niñas Aymaras (26,12, DE 5,63), pero la diferencia no fue estadísticamente significativa (p>0,05). El estudio encontró altos niveles de sobrepeso y obesidad en niños del norte de Chile, aumentando con la edad tanto para los grupos Aymaras como para los no Aymaras. Los patrones de somatotipo fueron consistentes en ambos grupos. Aunque las diferencias entre los niños Aymaras y no Aymaras no fueron estadísticamente significativas, el grupo Aymara mostró niveles ligeramente más altos de sobrepeso y obesidad. Se necesita más investigación con un tamaño de muestra más grande para confirmar estos resultados e identificar tendencias potenciales. Los esfuerzos deben centrarse en promover una nutrición saludable y la actividad física para abordar el creciente problema del sobrepeso y la obesidad en esta región.

Objetivo. Analizar los cambios en el sobrepeso, obesidad y alimentación de escolares del noroeste de México antes y después del aislamiento por COVID-19. Materiales y métodos. 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)

Perfil antropométrico de judocas de elite argentinos / Anthropometric profile of Argentine elite Judokas

Introducción: el judo es un deporte de combate cuya clasificación competitiva depende del peso corporal, lo cual está destinado a promover competencias parejas y equitativas en cuanto a capacidades físicas se refiere. El avance de las ciencias del entrenamiento y de la nutrición deportiva generó una mejora de la composición corporal en los deportistas, redundando en un aumento de los valores de masa muscular y en una disminución de la masa adiposa. El objetivo del estudio fue estimar la composición corporal de las personas que practican Judo participantes del campeonato nacional argentino del año 2021. Materiales y métodos: se realizó un estudio transversal descriptivo a los/as participantes del campeonato nacional de judo del año 2021. Fueron evaluados un total de 183 judocas (51 mujeres y 132 varones), según el protocolo de medición de la ISAK. Para la determinación de la composición corporal se utilizó el método de fraccionamiento anatómico de cinco componentes de Kerry Ross. Resultados: el promedio de las judocas fue de 30,5% para la masa adiposa y de 44,5% para la masa muscular; no se encontraron diferencias estadísticamente significativas en los distintos grupos de edad. Los varones obtuvieron un valor promedio de 22,4% para la masa adiposa y 49,1%para la masa muscular; en este caso se encontraron diferencias significativas entre los distintos grupos de edad, tanto para la masa adiposa como para la muscular y la masa ósea. Discusión: se necesitan más estudios con grupos estratificados en función de la división de peso corporal para poder establecer patrones de referencia específicos para el trabajo en ciencias del ejercicio y la nutrición. Conclusión: la optimización de la composición corporal de las personas que practican Judo redunda positivamente en la mejora de las capacidades físicas específicas. Los datos presentados constituyen una referencia específica de utilidad para la evaluación y seguimiento de las personas que practican Judo. La estratificación por grupos etarios y división de peso corporal permitirá delimitar mejor aún los valores de cada categoría de edad. Se considera relevante vincular la composición corporal con las pruebas físicas y los resultados deportivos, a fin de establecer un mejor perfil del judoca argentino. (AU)

Introduction: judo is a combat sport whose competitive classification depends on body weight, intended to promote even and equitable compe-titions in terms of physical abilities. Advances in the sciences of training and sports nutrition have led to an improvement in the body composition of athletes, resulting in an increase in muscle mass and a decrease in adipose mass. This study aimed to estimate the body composition of judo fighters participating in the 2021 Argentine National Championship. Materials and methods: we conducted a descriptive cross-sectional study of participants of the 2021 national judo championship. We evaluated 183 judokas (51 women and 132 men) applying the ISAK measurement protocol. We used the Kerry Ross five-component fractional anatomic method to determine body composition. Results: the average for female judo players was 30.5% for adipose mass and 44.5% for muscle mass; we found no statistically significant diffe-rences in the different age groups. The average value for males was 22.4% for adipose mass and 49.1% for muscle mass; in this case, we found significant differences between the different age groups for adipose mass and muscle and bone mass. Discussion: there is a need for more studies with stratified groups according to body weight division to establish specific reference standards for the work in exercise science and nutrition. Conclusion: the optimization of the body composition of female and male judo players has a positive effect on the improvement of specific physical capacities. The data presented constitute a relevant reference for the evaluation and follow-up of judokas. The stratification by age groups and body weight division will allow a better delimitation of the values of each age category. Linking body composition with physical tests and results is considered relevant to obtain a better profile of the Argentinian judo player. (AU)

Percentiles de peso, talla e índice de masa corporal de escolares de Mendoza. Comparación con la referencia de la Organización Mundial de la Salud / Body mass index, weight, and height percentiles in school-aged children from Mendoza. A comparison with the WHO reference

Introducción. La Organización Mundial de la Salud (OMS) recomienda el uso de tablas de referencia para monitorear el crecimiento y estado nutricional de niños, niñas y adolescentes. El peso corporal, la talla y el índice de masa corporal (IMC) son las variables más utilizadas. El presente trabajo tiene como objetivos estimar los percentiles de peso, talla e IMC de escolares (2009-2011) residentes en el departamento San Rafael (Mendoza) y compararlos con la referencia internacional de la Organización Mundial de la Salud, a fin de establecer su pertinencia para la evaluación del crecimiento y estado nutricional de dicha población. Población y métodos. Se realizó un estudio antropométrico transversal en 3448 escolares de entre 4,00 y 13,49 años de edad. Se utilizó el programa LMS ChartMarker Pro para calcular los valores percentilares de peso/edad, talla/edad e IMC/edad, por sexo y edad, y se compararon con las curvas de la OMS. Además, se calcularon diferencias porcentuales (D%) para estimar las diferencias y su significación estadística mediante prueba de Wilcoxon. Resultados. La población de San Rafael mostró, en varones y mujeres, valores percentilares superiores de peso e IMC (D% ≈7 % y 9 %, respectivamente), y menores de talla (D% ≈0,8 %) que los de la OMS (p <0,05). Conclusión. Las diferencias encontradas alertan sobre el empleo de la referencia OMS en la población escolar de San Rafael, ya que sobreestimaría las prevalencias de sobrepeso, obesidad y desnutrición crónica, y subestimaría la de desnutrición aguda y global. Esta situación resalta la importancia de contar con una referencia local.

Introduction. The World Health Organization (WHO) recommends the use of reference tables to monitor the growth pattern and nutritional status of children and adolescents. Body mass index (BMI), weight, and height are the most commonly used variables. The objective of this study was to estimate the BMI, weight, and height percentiles for school-aged children (2009-2011) living in the department of San Rafael (Mendoza) and compare them to the international World Health Organization reference to establish their relevance for the evaluation of the growth pattern and nutritional status of this population. Population and methods. A cross-sectional anthropometric study was conducted in 3448 school-aged children aged 4.00 to 13.49 years. The LMS ChartMarker Pro software was used to estimate the BMI- for-age, weight-for-age, and height-for-age percentiles, by sex and age, and they were compared with the WHO curves. Besides, percentage differences (%D) were calculated to estimate the differences and their statistical significance using the Wilcoxon test. Results. The population of boys and girls in San Rafael showed higher weight and BMI (%D ≈ 7% and 9%, respectively) percentiles, and lower height (%D ≈ 0.8%) values than WHO reference (p < 0.05). Conclusion. The differences found warn about the use of the WHO reference in the school-aged population of San Rafael since it would overestimate the prevalence of overweight, obesity, and chronic malnutrition and underestimate the prevalence of acute and global malnutrition. This situation highlights the importance of having a local reference resource

Variaciones morfológicas de la glándula submandibular en ratas obesas por acción de glutamato monosódico / Morphological variations of the submandibular gland in obese rats by the action of monosodium glutamate

Este estudio tuvo como objetivo demostrar la existencia de variaciones morfológicas en el tejido conectivo de la glándula submandibular de ratas obesas expuestas a glutamato monosódico (GMS). Se utilizaron 12 ratas Sprague Dawley machos recién nacidas (6 ratas para el grupo 1, control; 6 ratas para el grupo 2 (GMS), 4 mg/g de glutamato monosódico de peso (5 dosis) mantenidas por 16 semanas respectivamente con una dieta y agua ad libitum. En el estudio se realizó un análisis estereológico e histológico, demostrándose una variación en el tejido conectivo presentando una disminución del volúmen glandular, mayor fibrosis, y disminución de adipocitos a nivel periférico siendo reemplazado por tejido rico en colágeno. Los vasos sanguíneos observados a nivel estereológico no presentan mayores cambios en cuanto a volumen, superficie y área.

SUMMARY: This study aims to demonstrate the existence of morphological variations in the connective tissue of the submandibular gland of obese rats exposed to MSG. Twelve male newborn Sprague Dawley rats were used (6 rats for group 1, control; 6 rats for group 2 (MSG), 4 mg/g of monosodium glutamate of weight (5 doses) maintained for 16 weeks respectively with a diet and water ad libitum. In the study, a stereological and histological analysis was carried out, demonstrating a variation in the connective tissue, presenting a decrease in the glandular volume, greater fibrosis, and a decrease in adipocytes at the peripheral level, being replaced by tissue rich in collagen. Blood cells observed at the stereological level do not present major changes in terms of volume, surface and area, but in the histological study greater vascularization is observed.

Avaliação do consumo alimentar e estado nutricional de crianças menores de dois anos de uma comunidade quilombola / Assessment of food consumption and nutritional status of children under two years of age in a quilombola community / Evaluación del consumo de alimentos y del estado nutricional de niños menores de dos años en una comunidad quilombola

A Vigilância Alimentar e Nutricional é uma das diretrizes da Política Nacional de Alimentação e Nutrição, sendo considerada essencial para a atenção nutrição e monitoramento do estado nutricional e das práticas de consumo alimentar, possibilitando o reconhecimento de alimentos ou comportamentos que se relacionam à alimentação saudável e não saudável para fornecer subsídios para o planejamento e organização do cuidado. O objetivo deste estudo foi avaliar o consumo alimentar e o estado nutricional de crianças de 0 a 23 meses que residem na Comunidade Quilombola de Córrego dos Iús-CE. O percurso metodológico trata-se de um estudo do tipo pesquisa- intervenção, que consistiu em uma tendência das pesquisas participativas que busca compreender a vida de coletividades na sua diversidade qualitativa. Identificamos 11 crianças, menores de dois anos na comunidade. Devido às perdas, às recusas ou à ausência do responsável no domicílio, a amostra estudada foi composta por 9 participantes. A partir da avaliação antropométrica, verificamos os agravos nutricionais mais importantes foram o peso elevado para idade (44.4%), risco de sobrepeso para estatura e obesidade para estatura apresentaram respectivamente (11.1%), sobrepeso para IMC por idade (11.1%). Os achados sugerem que a população estudada esteja passando por uma transição nutricional. Nossa pesquisa nos permitiu perceber que as crianças pertencem as famílias de baixo poder econômico. É necessário a consolidação de políticas públicas para melhorar a saúde da comunidade estudada.

Food and Nutrition Surveillance is one of the guidelines of the National Food and Nutrition Policy, and is considered essential for nutritional care and monitoring of nutritional status and food consumption practices, enabling the recognition of foods or behaviors that are related to healthy eating and unhealthy to provide subsidies for the planning and organization of care. The objective of this study was to evaluate the food consumption and nutritional status of children aged 0 to 23 months living in the Quilombola Community of Córrego dos Iús-CE. The methodological course is a research- intervention type study, which consisted of a trend of participatory research that seeks to understand the life of collectivities in its qualitative diversity. We identified 11 children under two years of age in the community. Due to losses, refusals or the absence of the responsible person at home, the studied sample consisted of 9 participants. From the anthropometric assessment, we verified the most important nutritional problems were high weight for age (44.4%), risk of overweight for height and obesity for height presented respectively (11.1%), overweight for BMI for age (11.1%). The findings suggest that the studied population is going through a nutritional transition. Our research allowed us to realize that children belong to families with low economic power. It is necessary to consolidate public policies to improve the health of the studied community.

Atletas de Taekwondo apresentam desequilíbrio muscular entre os músculos flexores e extensores do joelho: achados preliminares / Taekwondo athletes have muscle imbalance between knee flexors and extensions: preliminary findings / Los atletas de Taekwondo presentan un desequilibrio muscular entre los flexores y los extensores de la rodilla: hallazgos preliminares

Durante a prática de taekwondo com movimentos repetitivos, sistematizados e com certa sobrecarga de treino, o indivíduo pode gerar possíveis adaptações orgânicas que resultam em problemas posturais com grandes chances de desencadear desequilíbrio muscular. Objetivo: Verificar a presença de desequilíbrio entre os grupos musculares agonistas e antagonistas da articulação do joelho e entre membros dominantes e não dominantes de praticantes de taekwondo por meio da dinamometria isocinética. Método: Estudo transversal, observacional e descritivo realizado com nove praticantes de taekwondo do sexo masculino. Utilizou-se um dinamômetro isocinético para investigar o pico de torque, pico de torque por peso corporal, trabalho total, potência média, relação agonista/antagonista e índice de fadiga. Os dados dos membros dominante e não dominante foram comparados por meio do teste t-student para amostras pareadas. Foram calculados o intervalo de confiança de 95% da diferença média, o tamanho de efeito e o poder das análises. Resultados: Os músculos extensores dos membros dominante e não dominante apresentaram diferença média significante de 15,49 Nm (IC95% 7,27; 23,70; p=0,002) para pico de torque e de 22,64% (IC95% 11,83; 33,46; p=0,001) para pico de torque por peso corporal a 60°/s, representando tamanho de efeito médio. Conclusão: Os atletas de taekwondo apresentaram maior pico de torque e maior pico de torque por peso corporal dos músculos extensores do joelho a 60º/s no lado dominante. A relação agonista/ antagonista foi inferior a 60% e mais da metade dos atletas apresentaram uma diferença maior que 10% no pico de torque flexor no lado não dominante.

During taekwondo practice with the repetitive motions, systematized and with certain training overload, the person can generate possible organic adaptations that result in postural problems with a great chances of triggering muscle imbalance. Objective: To verify the presence of imbalance between agonist and antagonist muscle groups of knee joint and between dominant and non-dominant limbs through isokinetic dynamometry. Methods: Cross-sectional, observational and descriptive study realized with nine male taekwondo practitioners. An isokinetic dynamometer was used to investigate the peak torque, peak torque by body weight, total work, average power, agonist/antagonist ratio and fatigue index. Data from the dominant and non-dominant limbs were compared by t-student test for pared samples. The 95% confidence interval of the mean difference, the effect size and the power of analyses power were calculated. Results: The extensor muscles of the dominant and non-dominant limbs showed mean difference of 15,49 Nm (IC95% 7,27; 23,70; p=0,002) for peak torque and of 22,64% (IC95% 11,83; 33,46; p=0,001) for peak torque by body weight at 60°/s, representing average effect size. Conclusion: The taekwondo athletes had higher peak torque and higher peak torque by body weight of the knee extensors muscles in the dominant side. The agonist/ antagonist ratio was less than 60% and more than half of the athletes showed a difference greater than 10% in the peak flexor torque on the non-dominant side.

Assessment of eating habits of preschool children and parent attitudes / Avaliação dos hábitos alimentares de pré-escolar e atitudes dos pais

ABSTRACT Objective The purpose of this study is to investigate preschoolers' eating behaviors and parents' attitudes. Methods This descriptive observational study employed a convenience sampling method to investigate the eating behavior of preschool children aged 3-6 years. Data was collected through a Personal and Parent Information Form and the Children's Eating Behavior Inventory. The study included 206 participants, and the findings provide insights into parental attitudes toward feeding and children's eating behaviors in 3-6 age group. Results The study sample included 206 parents of children between the ages of 3 and 6, with the majority of children having a normal weight. Parents' responses to the survey questions revealed significant correlations between children's weight percentiles and parental education level, maternal body mass index level, and income level. Positive eating behaviors in children were positively correlated with parental age and education level, income level, child age, and child percentile level, while negative eating behaviors were negatively correlated with parental age, educational status, income level, and positively correlated with maternal body mass index level. Gender differences were observed, with male children exhibiting lower mean scores in negative eating behaviors, maternal views and behaviors, child food preparation behavior, and negative meal situations compared to female children. Conclusion We found that parental education level and income level were correlated with children's positive eating behavior, while they were negatively associated with negative eating behavior. Negative eating behavior and food preparation behavior were lower in boys than in girls.

RESUMO Objetivo Este estudo observacional descritivo teve como objetivo investigar os comportamentos alimentares de crianças em idade pré-escolar e as atitudes dos pais. Métodos Foi utilizado um método de amostragem por conveniência para coletar dados sobre o comportamento alimentar de crianças com idades entre 3 e 6 anos. Foram aplicados um Formulário de Informações Pessoais e de Pais e o Inventário de Comportamento Alimentar Infantil, e a análise estatística foi realizada utilizando o programa IBM®SPSS® 16.0. O estudo contou com a participação de 206 pais fornecendo informações sobre as atitudes dos pais em relação à alimentação e os comportamentos alimentares das crianças na faixa etária de 3 a 6 anos. Resultados A amostra do estudo incluiu 206 pais de crianças com idades entre 3 e 6 anos, sendo a maioria das crianças com peso normal. As respostas dos pais às perguntas da pesquisa revelaram correlações significativas entre os percentis de peso das crianças e o nível educacional dos pais, índice de massa corporal materno e nível de renda. Comportamentos alimentares positivos nas crianças foram positivamente correlacionados com a idade e nível educacional dos pais, nível de renda, idade da criança e percentil de peso da criança, enquanto comportamentos alimentares negativos foram negativamente correlacionados com a idade dos pais, nível educacional, nível de renda e positivamente correlacionados com o índice de massa corporal materno. Foram observadas diferenças de gênero, com as crianças do sexo masculino apresentando pontuações médias mais baixas em comportamentos alimentares negativos, visões e comportamentos maternos, comportamento de preparação de alimentos infantis e situações negativas durante as refeições em comparação com as crianças do sexo feminino Conclusão Demonstra-se que o nível educacional e o nível de renda dos pais estão relacionados ao comportamento alimentar positivo das crianças, enquanto estão inversamente associados ao comportamento alimentar negativo. Comportamentos alimentares negativos e comportamentos de preparação de alimentos foram menores em meninos em comparação com meninas.

Transtornos alimentares: vivências de mulheres acima de 30 anos / Eating disorders: experiences of women aged over 30 years / Trastornos alimentarios: experiencias de mujeres de más de 30 años

O objetivo deste estudo foi compreender como mulheres adultas (acima de 30 anos) diagnosticadas com transtornos alimentares (TAs) vivenciam o adoecer. Trata-se de um estudo qualitativo, descritivo e exploratório, desenvolvido com base no referencial teórico-metodológico da Análise Fenomenológica Interpretativa (AFI). Participaram seis mulheres, com idades entre 34 e 65 anos, atendidas em um serviço especializado. Os dados foram coletados por meio de entrevista aberta, de inspiração fenomenológica, na modalidade remota. As entrevistas foram audiogravadas, transcritas e analisadas seguindo os passos da AFI. Duas categorias temáticas foram identificadas: "Vivendo antes do adoecer" e "Encontrando-se doente." Constatou-se que os sintomas tiveram início anteriormente à vida adulta e que houve dificuldade na confirmação do diagnóstico. Na perspectiva das participantes, conviver com a sintomatologia ficou mais complicado em função de particularidades de manejo dos sintomas na vida adulta, e a idade é percebida como um fator que impacta e dificulta ainda mais a recuperação. As participantes relataram desesperança em relação ao futuro, apesar de a maioria reconhecer melhoras no quadro clínico ao longo do tempo e de valorizar a relação de confiança estabelecida com a equipe multiprofissional.(AU)

This study aimed to understand the experience of illness of adult women (over 30 years) diagnosed with eating disorders (ED). This is a qualitative, descriptive, and exploratory study, using Interpretative Phenomenological Analysis (IPA) as theoretical and methodological framework. A sample of six women aged 34-64 years, assisted in a specialized service, were recruited to complete a phenomenological in-depth open interview. The data were remotely collected. Interviews were audio-recorded, transcribed and analyzed following the IPA. Two thematic categories were identified: "Living before the illness" and "Finding about the illness." It was found that the symptoms started before adulthood and that there was difficulty establishing the diagnosis. Living with the symptoms became more complicated due to particularities of symptom management in adulthood and age is perceived as a factor that impacts recovery and makes it even more difficult. The participants reported hopelessness about the future, although most recognized improvements in the clinical condition over time and valued the trusting relationship they established with the multiprofessional team.(AU)

El objetivo de este estudio fue comprender las experiencias de las mujeres adultas (mayores de 30 años) diagnosticadas con trastornos alimentarios (TA) respecto a la enfermedad. Se trata de un estudio cualitativo, descriptivo y exploratorio, desarrollado a partir del marco teórico y metodológico del Análisis Fenomenológico Interpretativo (AFI). Participaron seis mujeres, con edades de entre 34 y 65 años, atendidas en un servicio especializado. Los datos se recogieron mediante entrevistas abiertas, de inspiración fenomenológica, en la modalidad a distancia. Las entrevistas fueron grabadas en audio, transcritas y analizadas siguiendo los pasos del AFI. Se identificaron dos categorías temáticas: "Vivir antes de enfermar" y "Encontrarse enfermo." Se constató que los síntomas comenzaron antes de la edad adulta y que hubo dificultades de establecer el diagnóstico. La convivencia con síntomas se complicó debido a las particularidades del manejo de los síntomas en la vida adulta y la edad se percibe como un factor que influye y dificulta aún más la recuperación. Los participantes manifestaron desesperanza sobre el futuro, aunque reconocieron mejoras en el cuadro clínico con el paso del tiempo y valoraron la relación de confianza establecida con el equipo multiprofesional.(AU)

Effects of chronic restraint stress in the prostate of prepubertal and adult rats

Purpose: To investigate the effects of chronic stress in the prostate of prepubertal and adult rats. Methods: Thirty-two male rats were assigned into four groups depending on the type of treatment (control or stressed) and the age at which stress was initiated (prepubertal or adult). Restraint stress stimuli were applied for six weeks. Stressed prepubertal and adult rats evaluated immediately after the last stress stimuli were named SP and SA groups, respectively. Age-matched rats were used as control groups (CP and CA). At the end of the experiment, the rats were euthanized, and prostate morphological parameters were evaluated and statistically compared. Results: Application of stress stimuli to the SP group resulted in reduced body weight, but no prostate morphological modification was noted. The SA group showed reduced testosterone level and prostatic epithelium surface density, in comparison to CA group. Further, the prostatic lumen surface density was increased in adult stressed animals, in comparison to adult controls. Conclusions: The stress stimuli promoted changes in hormonal and morphological parameters in the prostate of adult stressed rats. Prepubertal stressed animals did not presented modifications of prostate morphology.

O nível de ansiedade, a renda e o acompanhamento psicológico podem influenciar na recorrência de peso corporal em mulheres submetidas a cirurgia bariátrica / Anxiety level, income and psychological monitoring can influence the recurrence of body weight in women submitted to bariatric surgery

Introdução: A melhora nos sintomas de ansiedade após a cirurgia bariátrica pode não permanecer estável em longo prazo, favorecendo a adoção de comportamentos alimentares disfuncionais. Objetivo: Testar a correlação entre o nível de ansiedade e a recorrência de peso em mulheres no pós-operatório tardio de cirurgia bariátrica e metabólica. Métodos: Foram avaliadas 50 mulheres adultas com no mínimo 24 meses após a cirurgia bariátrica e metabólica. Foram coletados dados sociodemográficos (idade, renda e nível de escolaridade) e de acompanhamento psicológico. Foram aferidos dados antropométricos (peso e altura). Para avaliar o nível de sintomas de ansiedade, foi utilizado o Inventário de Beck. Resultados: Foi encontrada média de idade de 40,9±11,4 anos. Todas apresentavam sintomas de ansiedade moderados a graves. Aquelas que estavam sem acompanhamento psicológico apresentavam maior peso corporal (p=0,049) e maior recorrência de peso (p=0,040). Observou-se correlação positiva entre o escore de ansiedade e a recorrência de peso, e correlação negativa entre o escore de ansiedade e a renda familiar. No modelo de regressão linear, a correlação entre o escore de ansiedade com a recorrência de peso (B=0,276; IC 0,003;0,594; p=0,048) e a renda (B=-0,310; IC -0,004;0,000; p=0,027) permaneceu significativa. Contudo, ao adicionar a variável "tempo de cirurgia", observou-se perda de significância entre ansiedade e recorrência de peso (B=0,270; IC -0,040; -0,624; p=0,083), mas manteve-se a correlação com a renda (B=-0,310; IC -0,004;-0,000; p=0,029). Conclusões: Ressalta-se a importância de suporte financeiro no pós-operatório, pelos custos com o tratamento, além de manter o acompanhamento com a equipe multiprofissional em longo prazo.

Introduction: The improvement in anxiety symptoms after bariatric surgery may not remain stable in the long term, favoring the adoption of dysfunctional eating behaviors. Objective: To test the correlation between anxiety level and weight recurrence in women in the late postoperative period of bariatric and metabolic surgery. Methods: Fifty adult women with at least 24 months after bariatric and metabolic surgery were evaluated. Sociodemographic data (age, income and level of education) and psychological monitoring were collected. Anthropometric data (weight and height) were measured. To assess the level of anxiety symptoms, the Beck Anxiety Inventory was used. Results: A mean age of 40.9±11.4 years was found. All had moderate to severe anxiety symptoms. Those who were without psychological support had higher body weight (p=0.049) and greater recurrence of weight (p=0.040). There was a positive correlation between the anxiety score and body weight recurrence, and a negative correlation between the anxiety score and family income. In the linear regression model, the correlation between anxiety score and weight recurrence (B=0.276; CI 0.003; 0.594; p=0.048) and income (B=-0.310; CI -0.004; 0.000; p=0.027) remained significant. However, when adding the variable "surgery time", there was a loss of significance between anxiety and weight recurrence (B=0.270; CI -0.040; -0.624; p=0.083), but the correlation with income was maintained (B=-0.310; CI -0.004; -0.000; p=0.029). Conclusions: We emphasize the importance of financial support in the postoperative period, due to treatment costs, in addition to maintaining monitoring with the multidisciplinary team in the long term.

Grupo multifamiliar em transtornos alimentares durante a primeira onda da pandemia de covid-19: transição para a modalidade online / Multifamily group on eating disorders during the first wave of the covid-19 pandemic: transitioning to the online modality / Grupo multifamiliar de trastornos alimentarios durante la primera ola de la pandemia de la covid-19: transición a la modalidad en línea

As restrições impostas pela pandemia de covid-19 levaram os serviços de saúde a reorganizarem seu funcionamento, ajustando-se à modalidade remota. A transição repentina e sem o devido preparo técnico impôs desafios adicionais para usuários e profissionais. Para aprimorar as estratégias assistenciais, torna-se imprescindível dar voz aos usuários dos serviços, para que narrem suas experiências e possam manifestar suas facilidades e dificuldades com essa passagem. Este estudo tem como objetivo investigar como os principais cuidadores familiares de pessoas com transtornos alimentares vivenciaram a transição do grupo de apoio para o formato remoto e identificar vantagens e desvantagens percebidas nesse modelo. Estudo clínico-qualitativo, exploratório, realizado em um serviço de atendimento especializado de um hospital terciário. O cenário investigado foi o grupo de apoio psicológico aberto a familiares que, desde o início da pandemia de covid-19, passou a ser oferecido na modalidade online. Participaram do estudo cinco mães e três pais presentes em 13 sessões grupais consecutivas. Entrevistas individuais foram aplicadas com a Técnica do Incidente Crítico logo após o término de cada encontro grupal, totalizando 26 entrevistas audiogravadas, transcritas e submetidas à análise temática. A transição para o online foi vivenciada pelos participantes como um recurso válido para permitir que o grupo funcionasse em tempos de grave crise sanitária. Como vantagens, foram mencionadas: a continuidade do cuidado, maior acessibilidade e facilidade em relação à logística da participação. Como limitações do formato online, foram destacadas: nem todos os familiares contam com conexão de internet de qualidade e possível dificuldade para manusear a tecnologia digital. Apesar dos desafios impostos pela súbita mudança para a modalidade online, na perspectiva dos usuários do serviço os esforços de adaptação foram bem-sucedidos, possibilitando a continuidade do cuidado à saúde mental.(AU)

The constraints imposed by the COVID-19 pandemic led health services to reorganize their operation, adjusting to the online modality. The sudden and unprepared technical transition has imposed additional challenges for both users and professionals. To improve care strategies, it is essential to give voice to services users, so that they can narrate their experiences and express their facilities and difficulties with this transition. This study aims to investigate how main family caregivers of people with eating disorders experienced the transition of the support group to the remote modality and to identify perceived advantages and disadvantages in this model. This is a clinical-qualitative, exploratory study carried out in a specialized care service of a tertiary hospital. The investigated setting was the psychological support group open to family members, which since the beginning of the COVID-19 pandemic has been offered online. Five mothers and three fathers who attended 13 consecutive group sessions participated in the study. Individual interviews were carried out with the Critical Incident Technique shortly after the end of each group meeting with all members, totaling 26 audio-recorded interviews. Data were subjected to thematic analysis. Transition was experienced as a valid resource to maintain the group active in times of a severe health crisis. As advantages of the remote modality were mentioned: continuity of care, greater accessibility, and ease in relation to the logistics of participation. As limitations of the online format were highlighted: not everyone has a good-quality connection to the internet, and difficulty in handling the digital technology. Despite the challenges imposed by the sudden shift to the online modality, from the service users' perspective the adaptation efforts were successful, enabling continuity of mental health care.(AU)

Las limitaciones que impuso la pandemia de la COVID-19 llevaron a los servicios sanitarios a reorganizar su funcionamiento adaptándose a la modalidad remota. El súbito cambio y sin la preparación técnica adecuada implicó retos adicionales a los usuarios y profesionales. Para mejorar las estrategias de atención es fundamental dar voz a los usuarios de los servicios, para que puedan narrar sus experiencias y expresar sus facilidades y dificultades con esta transición. Este estudio pretende investigar cómo han vivido los cuidadores de personas con trastornos alimentarios la transición del grupo de apoyo presencial al formato remoto e identificar las ventajas y desventajas percibidas en este modelo. Se trata de un estudio clínicocualitativo, exploratorio. El escenario investigado fue el grupo de apoyo psicológico abierto a los familiares en la modalidad en línea. Cinco madres y tres padres participaron en 13 sesiones de grupo consecutivas. Se realizaron entrevistas individuales con la técnica de incidentes críticos inmediatamente después de cada reunión del grupo, con un total de 26 entrevistas grabadas en audio, transcritas y sometidas a análisis temático. La transición a la red fue experimentada como un recurso válido para permitir que el grupo funcione en tiempos de crisis sanitaria grave. Las ventajas de la modalidad remota fueron conexión segura en tiempos de confinamiento físico, continuidad, mayor accesibilidad y facilidad en relación con la logística de la participación. Las limitaciones del formato en línea fueron la falta de una conexión de calidad a Internet y la posible dificultad de manejo de la tecnología digital. A pesar de las dificultades impuestas por el cambio repentino a la modalidad en línea, desde la perspectiva de los usuarios del servicio los esfuerzos de adaptación fueron un éxito, lo que permitió seguir con la atención de salud mental.(AU)

Measurement of the Thermic Effect of Food in a Chinese Mixed Diet in Young People / 生物医学与环境科学（英文）

OBJECTIVE@#To determine the thermic effect of food (TEF) in a Chinese mixed diet in young people.@*METHODS@#During the study, the participants were weighed and examined for body composition every morning. The total energy expenditure (TEE) of the participants was measured by the doubly labeled water method for 7 days, and during this period, basal energy expenditure was measured by indirect calorimetry and physical activity energy expenditure was measured by an accelerometer. The value obtained by subtracting basal energy expenditure and physical activity energy expenditure from TEE was used to calculate TEF.@*RESULTS@#Twenty healthy young students (18-30 years; 10 male) participated in the study. The energy intake of the participants was not significantly different from the Chinese Dietary Reference Intake of energy ( P > 0.05). The percentage of energy from protein, fat and carbohydrate were all in the normal range. The intakes of fruits, milk and dietary fiber of the participants were significantly lower than those in the Chinese Dietary Guidelines ( P < 0.05). There was no significant difference in the body weight of the participants during the experiment ( P > 0.05). When adjusted for body weight, there was no significant difference in either TEE or basal energy expenditure between the male and female participants ( P > 0.05). In addition, there was no significant difference in physical activity energy expenditure and TEF between the male and female participants ( P > 0.05). The percentage of TEF in TEE was 8.73%.@*CONCLUSION@#The percentage of TEF in TEE in a Chinese mixed diet in young people was significantly lower than 10% ( P < 0.001). A value of 10% is usually considered to be the TEF in mixed diets as a percentage of TEE.
