Obesity is a global health problem that affects not only adults and older adults, but also children and adolescents, thus recognizing the need to adapt the educational intervention programs of the Ministry of Education, in partnership with the Ministry of Public Health, to adapt them to the children's universe. It has been demonstrated in practice that physical activity is an ideal space for the educational inclusion of all schoolchildren; we have moved from the paradigm of integration to the paradigm of inclusion, where everyone enjoys differentiated attention according to their needs. It is the authors' purpose to communicate about an educational intervention applied to 9-year-old children with obesity and overweight, with actions that modify their lifestyle and educate the family to face this alarming health problem in this age group.

Background: Pulmonary congestion is a strong predictor of mortality and cardiovascular events in chronic kidney disease (CKD); however, the effects of the mild form on functionality have not yet been investigated. The objective of this study was to assess the influence of mild pulmonary congestion on diaphragmatic mobility (DM) and activities of daily living (ADL) in hemodialysis (HD) subjects, as well as compare ADL behavior on dialysis and non-dialysis days. In parallel, experimentally induce CKD in mice and analyze the resulting pulmonary and functional repercussions. Methods: Thirty subjects in HD underwent thoracic and abdominal ultrasonography, anthropometric assessment, lung and kidney function, respiratory muscle strength assessment and symptoms analysis. To measure ADL a triaxial accelerometer was used over seven consecutive days. Twenty male mice were randomized in Control and CKD group. Thoracic ultrasonography, TNF-α analysis in kidney and lung tissue, exploratory behavior and functionality assessments were performed. Results: Mild pulmonary congestion caused a 26.1% decline in DM (R2 = .261; P = .004) and 20% reduction in walking time (R2 = .200; P = .01), indicating decreases of 2.23 mm and 1.54 min, respectively, for every unit increase in lung comet-tails. Regarding ADL, subjects exhibited statistically significant differences for standing (P = .002), walking (P = .034) and active time (P = .002), and number of steps taken (P = .01) on days with and without HD. In the experimental model, CKD resulted in increased levels of TNF-α on kidneys (P = .037) and lungs (P = .02), attenuation of exploratory behavior (P = .01) and significant decrease in traveled distance (P = .034). Thoracic ultrasonography of CKD mice showed presence of B-lines. Conclusion: The mild pulmonary congestion reduced DM and walking time in subjects undergoing HD. Individuals were less active on dialysis days. Furthermore, the experimental model implies that the presence of pulmonary congestion and inflammation may play a decisive role in the low physical and exploratory performance of CKD mice. Resumen: Antecedentes: La congestión pulmonar es un fuerte predictor de mortalidad y eventos cardiovasculares en la enfermedad renal crónica (ERC); sin embargo, aún no se han investigado los efectos de la forma leve sobre la funcionalidad. El objetivo de este estudio fue evaluar la influencia de la congestión pulmonar leve en la movilidad diafragmática (MD) y las actividades de la vida diaria (AVD) en sujetos en hemodiálisis (HD), así como comparar el comportamiento de las AVD en los días de diálisis y no diálisis. Paralelamente, inducir de forma experimental la ERC en ratones y analizar las repercusiones pulmonares y funcionales resultantes. Métodos: Treinta sujetos en HD fueron sometidos a ecografía torácica y abdominal, evaluación antropométrica, función pulmonar y renal, evaluación de la fuerza de los músculos respiratorios y análisis de síntomas. Para medir las AVD se utilizó un acelerómetro triaxial durante 7 días consecutivos. Se aleatorizaron 20 ratones machos en el grupo control y con ERC. Se realizó ecografía torácica, análisis de TNF-α en tejido renal y pulmonar, comportamiento exploratorio y evaluaciones de funcionalidad. Resultados: La congestión pulmonar leve provocó una disminución del 26,1% en la MD (R2 = ,261; P = ,004) y una reducción del 20% en el tiempo de caminata (R2 = 0,200; P = ,01), lo que indica disminuciones de 2,23 mm y 1,54 minutos, respectivamente, por cada unidad de aumento de las colas de cometa pulmonares. En cuanto a las AVD los sujetos mostraron diferencias estadísticamente significativas para estar de pie (P = ,002), caminar (P = ,034) y tiempo activo (P = ,002) y número de pasos dados (P = ,01) en los días con y sin HD. En el modelo experimental la ERC resultó en un aumento de los niveles de TNF-α en los riñones (P = ,037) y los pulmones (P = ,02), la atenuación del comportamiento exploratorio (P = ,01) y una disminución significativa en la distancia recorrida (P = ,034). La ecografía torácica de ratones con ERC mostró la presencia de líneas B. Conclusión: La leve congestión pulmonar redujo la MD y el tiempo de marcha en sujetos sometidos a HD. Los individuos eran menos activos en los días de diálisis. Además, el modelo experimental implica que la presencia de congestión e inflamación pulmonar puede desempeñar un papel decisivo en el bajo rendimiento físico y exploratorio de los ratones con ERC.

Introduction: Some previous evidence supports the fact that physical activity is associated with resilience in different populations; however, the results are inconsistent. Objective: To determine the prevalence of resilience; and the association between physical activity and resilience during the pandemic in a sample of medical students. Methods: Cross-sectional study in 508 medical students. Resilience was categorized as adequate and low, while physical activity was categorized as low, medium and high. To assess the strength and magnitude of association, Poisson regression with robust variance was used. The results were presented in crude and adjusted prevalence ratios (aPR) with their 95% confidence intervals (95% CI). The confounding variables were sex, academic year; having been diagnosed with COVID-19 and having relatives diagnosed with COVID-19. Results: The prevalence of adequate resilience was 40.35%. In the multivariable regression analysis, the presence of those who performed high physical activity increased the prevalence of adequate resilience by 1.56 times (aPR=1.56; 95% CI 1.23-1.97) compared to those who performed low physical activity. No association with moderate physical activity was found. Conclusions: Less than half of the medical students presented an adequate level of resilience. At the same time, an association was found with high physical activity.

Objetivo: determinar la prevalencia de síntomas de ansiedad y depresión, al igual que su asociación con el tiempo de pantalla, la dieta y la actividad física, en una cohorte de estudiantes de enfermería. Método: estudio descriptivo y transversal sobre una muestra de 648 estudiantes de enfermería. Se utilizaron la Hospital Anxiety and Depression Scale, la versión corta del International Physical Activity Questionnaire y el Índice de Alimentación Saludable español. Se llevaron a cabo diferentes modelos de regresión lineal múltiple para analizar la asociación entre los síntomas de ansiedad y depresión, y el tiempo de pantalla, la dieta y la actividad física. Resultados: la prevalencia de síntomas de ansiedad y depresión fue de 24,1% y 3,7%, respectivamente. El tiempo de pantalla prolongado (>6 horas por día), baja actividad física y dieta inadecuada se asociaron de manera independiente y significativa con una mayor sintomatología psicológica. Conclusión: la salud mental de los estudiantes de enfermería podría beneficiarse de implementarse iniciativas que promuevan estilos de vida saludables.

El objetivo de este estudio fue determinar los valores centiles de la coordinación motriz para escolares entre 10 y 14 años de los municipios del departamento del Atlántico, Colombia. Se diseñó un estudio transversal con muestreo aleatorio simple (MAS) en colegios públicos y privados. La coordinación motriz se midió con el test motor complejo. Los datos se analizaron con el programa SPSS. Se establecieron valores normativos por edad y sexo, expresados en percentiles P3, P10, P25, P50, P75, P90 y P97. Con este estudio se plantean los primeros valores de referencia en la coordinación motriz por edad y sexo para escolares de las ciudades de un departamento de la costa atlántica colombiana para determinar la habilidad motriz de los niños.

Objetivo: describir los patrones de actividad física de una cohorte de gestantes de nuestro medio y explorar su asociación con la ganancia de peso en cada uno de los trimestres del embarazo. Método: estudio descriptivo longitudinal sobre una muestra de 151 mujeres. Se utilizó el Cuestionario Internacional de Actividad Física para evaluar la actividad física durante el embarazo en función del volumen, intensidad y ámbito de realización. Se llevaron a cabo diferentes modelos de regresión lineal múltiple para analizar la asociación entre actividad física y ganancia de peso gestacional. Resultados: la actividad física disminuyó durante el embarazo, tanto en tiempo como en intensidad. El índice de masa corporal pre-gestacional fue el principal factor asociado con una menor ganancia de peso a lo largo de todo el embarazo. La influencia de la actividad física sobre la ganancia de peso gestacional se limitó al tercer trimestre del embarazo en el que se observó una asociación inversa entre ambas variables. Conclusión: los resultados de este estudio muestran un importante descenso de la actividad física en la época del embarazo y sugieren una influencia limitada de ésta sobre la ganancia de peso gestacional.

This study aimed to correlate cognitive function with the physical activity level (pal) and physical fitness over three years of patients undergoing hemodialysis and to compare the pal and physical fitness over this period of patients with and without cognitive problems. Therefore, a cohort study was carried out, including patients evaluated between 2018 and 2020, through the Mini-Mental State Exam, functional physical record, Elbow Flexion test, Sit-to-stand test, Handgrip Strength test (hgs), and by the physical activity monitor. Data analysis was performed using the Pearson's Correlation test and the paired Student's t-test and its non-parametric equivalent, when necessary, with a significance level of 5%. The results showed that cognitive function assessed in the different years of the research was positively correlated with physical fitness and with pal: in 2018, with hgs (r = 0.313; p = 0.019); in 2019, with cardiorespiratory fitness (r = 0.288; p = 0.038), with hgs (r = 235; p = 0.033) and with pal on hd days (r = 359; p = 0.010) and on days without treatment (r = 314; p = 0.026); and in 2020, with the pal up to date without hd (r = 387; p = 0.014). In addition, patients without probable cognitive deficit had higher pal and physical fitness values in all years of analysis compared to those with the probable cognitive deficit: in 2018, this difference was significant in hgs and pal on a day contrary to hemodialysis; in 2019, in cardiorespiratory fitness and pal on a day contrary to treatment; and in 2020, in cardiorespiratory fitness, hgs and pal on both days. It is concluded that patients with higher pal and better physical fitness had a better cognitive function, suggesting the importance of physical activity practice as an effective alternative in improving physical fitness and, consequently, cognitive function in hd patients.

Objective: To evaluate the level of physical activity, sitting hours and Body Mass Index in a university community associated with the mandatory isolation decreed due to the COVID-19 pandemic. Method: Descriptive, cross-sectional study in workers, teachers and students with an age range of 18 to 59 years, carried out between February and April 2021 with convenience sampling. The body mass index was determined and the International Physical Activity Questionnaire, short version endorsed for Colombia, was applied. Results: A total of 52 people were evaluated, 35 women (67.3%) and 17 men (32.7%), mean age of 37.6 years ± 11.4, mean BMI of 25.9 kg/m² ± 3.8. The BMI level showed excess weight in 67.9% of the group aged 39 or over. In the younger group only 4.2% showed levels of obesity. People with low weight level were not found. A low level of physical activity was found in 57.7% of the participants, 15.4% showed a moderate level and 26.9% showed a high level of physical activity. The sitting hours of the elderly was found to be 8.4 hours per day. Conclusions: Changes in lifestyle associated with mandatory isolation had a negative impact on the level of physical activity, on the body mass index and on the number of hours sitting for the members of the university community.

Objetivo. Analizar el efecto de la actividad física (AF) sobre la calidad de vida (CV) en personas de 15 años o más, consi­derando características sociodemográficas, epidemiológicas y psicosociales levantadas en una encuesta nacional. Material y métodos. Estudio cuantitativo-analítico-transversal de­sarrollado en Chile 2020, a partir de estadística descriptiva e inferencial. Resultados. Edad promedio de 49 años, 63% de sexo femenino. Un 15% informó practicar algún deporte o entrenar de manera intensa; 75% tiene una buena o muy buena CV y 53% buena o muy buena CV en salud. Quienes practi­caban algún deporte intenso tenían más posibilidad de tener una buena o muy buena CV (RM=1.58; IC95%= 1.28,1.96) y CV asociada a la salud (RM=1.67; IC95%= 1.40,1.99) en comparación con quienes no practicaban. Conclusiones. La AF es un aspecto que impacta positivamente en la CV de las personas y en la salud general de la población, además de que es económica y fácil de instaurar.

INTRODUCCIÓN: Las Enfermedades Crónicas No Transmisibles (ECNT) representan las principales causas de muerte en Argentina y la identificación temprana de sus factores de riesgo (FR) es clave para su prevención. El objetivo de este estudio fue describir la frecuencia de FR y ECNT en estudiantes de la Universidad Nacional de La Matanza. MÉTODOS: Se realizó un estudio de corte transversal, utilizando un cuestionario adaptado de la Encuesta Nacional de Factores de Riesgo por autorreporte, para describir los FR y su asociación con características sociodemográficas. RESULTADOS: Se encuestaron 130 estudiantes de ambos sexos. El 6,9% identificó su salud como “regular” y un 48,5% algún grado de ansiedad o depresión. El 26,2% reportó bajo nivel de actividad física y casi todos los encuestados consumieron menos de 5 porciones de frutas y verduras al día. Un 6,2% reportó ser fumador y un 38,5% estar expuesto al humo del tabaco. La prevalencia de sobrepeso fue de 23,2% y de obesidad de 6,4%. El 20,4% y el 16,8% de los estudiantes informaron respectivamente colesterol y presión arterial elevados “alguna vez”. CONCLUSIÓN: El ámbito universitario es un espacio ideal para el abordaje de actividades de promoción y prevención de estos FR.

Objective. To analyze the effect of Physical Activity (PA) on the Quality of Life (QL) of people aged 15 years and over considering sociodemographic, epidemiological, and psychosocial characteristics collected in a national survey carried out in Chile. Materials and methods. Quantitativeanalytical-transversal developed in Chile 2020. Descriptive and inferential statistics. Results. Average age of 49 years, 63% female. 15% reported practicing some sport or training intensely; 75% have a good or very good QL, and 53% have a good or very good QL in health. Those who practiced an intense sport were more likely to have a good or very good QL (OR= 1.58; 95%CI= 1.28,1.96) and QL associated with health (OR= 1.67; 95%CI= 1.40,1.99) compared to those who did not do it. Conclusions. PA is an aspect that impacts people's QL, cheap, easy to establish, and positively impacts the general health of the population. [ABSTRACT FROM AUTHOR]

Objective. To synthesize the findings on correlates of physical activity (PA) and sedentary behavior (SB) in South American children. Method. A search was carried out from June 24 to October 27, 2020, in the LILACS, PubMed, SciELO, Scopus and Web of Science databases. To broaden the search, the references of identified review articles were examined, and a panel of experts was surveyed. Observational and interventional studies conducted with South-American children from zero to 5 years of age were included. Results. Of 3 111 articles initially identified, 18 were eligible: 14 observational studies, 12 studies conducted in Brazil, and 17 studies investigating preschool children (3 to 5 years of age). In addition to Brazil, only Chile and Ecuador were represented. PA and SB were measured by accelerometers in seven studies; however, high variability was observed in the instruments and cut-off points used. Although children were classified as physically active in 12 studies, six studies showed that they spent considerable time in SB. Most studies assessed the individual (14 studies) and interpersonal (11 studies) domains, followed by the environmental (eight studies) and political (one study) domains. Interventions in the school context (four studies) increased PA levels and reduced the time spent in SB. However, the evidence from cross-sectional and interventional studies presented a high risk of bias. Conclusions. Given the knowledge gap identified in this review, studies with robust designs, covering additional South American countries are warranted, focusing on infants and children under 3 years of age and investigating correlates in the environmental and political domains.

In Peru, one of the first interventions to flattened the epidemiologic curve of the pandemic was quarantine that changed eating behavior, physical activity and mental health of the population. Objective: to determine modifications in eating behavior, physical activity and mental health in young adults before and after the quarantine. Methods: cohort study involving 384 adults from 18 to 24 years of age that were subjected to a virtual interview and application of an international questionnaire to evaluate changings in eating behavior, physical activity and mental health contrasted by Chi square. Results: an increase in the distribution of daily foods [breakfast (p<0.001), morning snack (p<0.05), lunch (p<0.001), afternoon snack (p<0.001), dinner (p<0.05)] and an increase in ingestion of fruits (p=0.005) and reduction in the ingestion of fast food (p<0.05) and candies (p=0.03). Physical activity decreases specially in males vs females (28.4% vs. 25.3%) and there was a reduction in the total number of sleep hours, mental health was severely affected. Conclusions: quarantine induced variations in eating behavior, reduction in physical activity and increase in mental health disorders. These modifications put the population at risk for weight gain or obesity and eventually to non-transmissible diseases. [ABSTRACT FROM AUTHOR]

Introduction: The paramedian lobule of the cerebellum is involved in learning to correctly perform motor skills through practice. Dendritic spines are dynamic structures that regulate excitatory synaptic stimulation. We studied plastic changes occurring in the dendritic spines of Purkinje cells from the paramedian lobule of rats during motor learning. Methods: Adult male rats were trained over a 6-day period using an acrobatic motor learning paradigm; the density and type of dendritic spines were determined every day during the study period using a modified version of the Golgi method. Results: The learning curve reflected a considerable decrease in the number of errors made by rats as the training period progressed. We observed more dendritic spines on days 2 and 6, particularly more thin spines on days 1, 3, and 6, fewer mushroom spines on day 3, fewer stubby spines on day 1, and more thick spines on days 4 and 6. Conclusion: The initial stage of motor learning may be associated with fast processing of the underlying synaptic information combined with an apparent “silencing” of memory consolidation processes, based on the regulation of the neuronal excitability. Resumen: Introducción: El lóbulo paramediano del cerebelo está involucrado en el desempeño correcto de las habilidades motoras a través de la práctica. Las espinas dendríticas son estructuras dinámicas que regulan la estimulación sináptica excitadora. En este trabajo se estudiaron los posibles cambios plásticos en espinas de células de Purkinje del lóbulo paramediano cerebelar de ratas, durante el aprendizaje motor. Métodos: Se entrenaron a ratas macho adultas durante un período de seis días, en un paradigma de aprendizaje motor acrobático y se cuantificó tanto la densidad como los tipos de espinas dendríticas en cada uno de los seis días de estudio, mediante una modificación al método de Golgi. Resultados: La curva de aprendizaje reflejó una disminución consistente de los errores cometidos en el transcurso de los días de entrenamiento. Así mismo, se observaron más espinas dendríticas en los días 2 y 6 y, en particular, más espinas delgadas en los días 1, 3 y 6, menos espinas en hongo el día 3, menos espinas gordas el día 1 y más espinas anchas los días 4 y 6. Conclusión: El período inicial de aprendizaje motor podría estar asociado con el procesamiento rápido de la información sináptica subyacente y con un aparente «silenciamiento» de los procesos de consolidación mnémica, en una base de regulación de la excitabilidad neuronal.

El presente trabajo tiene como propósito caracterizar las políticas públicas que, en materia de actividad física, deporte y recreación se desarrollaron en la República Bolivariana de Venezuela en el período que abarca los años 1999 y 2014. Para ello se ha privilegiado la investigación retrospectiva, usando el método histórico a través de la técnica documental en función de materiales como memorias y cuenta de los ministerios responsables, páginas web oficiales de instituciones del Estado, declaraciones de responsables como ministros, decretos, leyes, balances de gestión, documentos elaborados por asesores del Estado en el período señalado. Se ha encontrado que las políticas públicas en materia de actividad física, deporte y recreación en Venezuela tienen una reorientación si se comparan con las que venían en desarrollo antes del período señalado entre 1999 y 2014, se generan políticas en campos como la recreación que hasta 1999 jamás se habían desarrollado, entre otros elementos. Finalmente, se encuentra que existen elementos necesarios para corregir durante el proceso de desarrollo y puesta en ejecución.

Objetivo: Evaluar los procesos de una intervención de actividad física durante el embarazo y postparto. Métodos: En el contexto de un programa social que combate la pobreza extrema, las beneficiarias (n=927) recibieron una intervención que consistió en la promoción de la práctica de actividad física, a través de consejería, talleres y materiales educativos. En 2008-9, 2010 y 2012 se visitaron unidades de salud urbanas y rurales, seleccionadas aleatoriamente, de cuatro entidades federativas de México. Se recolectó información de procesos a través de prestadores de servicios de salud, observación en consulta y aplicación de encuestas de salida a beneficiarias. Se estudiaron cuatro indicadores de implementación de la intervención: fidelidad a actividades planeadas; dosis entregada a la población; alcance de la población objetivo; y recepción de la intervención por embarazadas y en el posparto de las participantes. Resultados: Se visitaron unidades de salud en la etapa inicial (n=91), intermedia (n=47) y final (n=82) del estudio. La dosis liberada presentó un nivel del 81-86% de implementación. La fidelidad presentó

OBJETIVO: Analizar las políticas públicas vinculadas al control de las Enfermedades Crónicas No Transmisibles (ECNT) mediante la promoción de la actividad física (AF) en la ciudad de Rosario entre 2003 y 2017. MÉTODO: Se consideraron aquellas intervenciones públicas con finalidad de fomentar la AF en Rosario, reglamentadas por normativa entre 2003-2017. Normativas y contenidos de los sitios web oficiales de la provincia de Santa Fe y la municipalidad de Rosario fueron analizados mediante la técnica de análisis de contenido. RESULTADOS: Fueron captadas 35 intervenciones. Nueve intervenciones se propusieron explícitamente controlar las ECNT y solo una de ellas estuvo focalizada en la población socioeconómicamente vulnerable. CONCLUSIONES: La política de promoción de la AF en Rosario experimentó un impulso acentuado a partir del final de la década del 2000, estuvo mayormente dirigida a la población general y comenzó a explicitar su vinculación con las ECNT desde el inicio de la década siguiente.
