Workers’ attitudes towards people with disabilities can influence labor inclusion. Despite the relevance of learning about these attitudes, in Chile, there are no reliable and validated instruments to measure them in workers. An instrumental study was carried out to adapt and psychometrically analyze the Spanish version of the Scale of Attitudes towards People with Disabilities (EAPCD) in the Chilean population. By means of a non-probabilistic convenience sampling, 310 people between 19 and 76 years of age (M = 39.4; SD = 11.2) from different regions of Chile participated in the study. The linguistic adaptation included the change in Spanish idioms and expressions to the Chilean context, whose relevance was validated with cognitive interviews. Descriptive analysis, internal consistency analysis, and CFA (confirmatory factor analysis) were performed. The CFA indicated an adequate fit to the three-factor model proposed in the original scale (χ2(431) = 808.070, p < 0.01; RMSEA = 0.053; CFI = 0.93; TLI = 0.93). The Social Relations and Normalization dimensions were reliable; however, it is recommended that the items of the Intervention Programs dimension be revised or eliminated, since they could be confusing in the local context. It is concluded that the scale is reliable and valid to evaluate attitudes towards the inclusion of people with disabilities in Chile in the work context.

The main objectives of this study were to adapt the AUTODDIS scale to the cultural and social dimensions of Chile and to analyze its reliability and validity. The reliability and validity were assessed through a pilot study conducted with a population of students with intellectual disabilities (ID). The linguistic adaptation was executed according to expert judgments of each indicator: adequacy, coherence, relevance, and clarity. After the scale adaptation, a scale pilot was conducted to explore its technical properties. It was performed in a public school for students with ID. The validity coefficient result was 0.998, while the complete reliability result was α = 0.978. For the reliability subscales, the results were the following: autonomy α = 0.941, self-initiation α = 0.925, self-direction α = 0.970, self-regulation α = 0.804, and self-concept α = 0.935. The results confirm the AUTODDIS scale as a valid and reliable instrument to evaluate self-determination. However, it is necessary to apply this scale to a larger number of students with ID to generalize these results.

Aunque las investigaciones actuales indican que el modo activo de desplazamiento influye en la salud de los escolares, lo que se sabe sobre la relación entre la condición física autoinformada y su relación con la forma de desplazarse activamente hacia y desde la escuela (ACS, por sus siglas en inglés) se sabe menos. Los objetivos de este estudio fueron a) analizar la aptitud física autoinformada y la ACS, y b) determinar la asociación entre la aptitud física autoinformada con ACS a través de una encuesta realizada en el sur de Chile. Se realizó un diseño analítico transversal. La muestra estuvo compuesta por 733 escolares (de 10 a 16 años, 46,1% niñas) de colegios públicos chilenos. Se utilizó la International Fitness Scale (IFIS) para determinar la aptitud física autoinformada. Se evaluaron los modos de desplazamiento de los estudiantes a la escuela mediante preguntas separadas sobre ACS. Los principales resultados mostraron que los niños presentaron una mejor aptitud física autoinformada que las niñas, excepto en la autopercepción de flexibilidad (p= 0,041). Además, se observó asociación entre el tipo de ACS y la flexibilidad autoinformada (OR:1,53, p=0,022; OR:1,47, p= 0,036), asociación que se mantuvo al ajustar por sexo y la edad (OR:1,55, p=0,020; OR:1,50, p= 0,030), la velocidad y la agilidad autoinformada se asociaron sólo con el desplazamiento activo desde la escuela (OR:1,60, p=0,005), también después del modelo ajustado (OR:1,81, p=0,024). En conclusión, este estudio proporciona evidencia sobre la relación entre la aptitud física autoinformada y las formas de ACS. Para promover la salud en los escolares se deben buscar estrategias que favorezcan los ACS.

La obesidad es vinculada a una inflamación crónica que altera no sólo los marcadores inflamatorios sino también al sistema nervioso autonómico, estableciendo una predominancia simpática conduciendo a un riesgo cardiovascular. De esa manera el entrenamiento cardiovagal es reconocido un tratamiento que no sólo modifica la condición física sino también responde a regular el sistema autonómico y a los marcadores inflamatorios. El objetivo de este estudio fue analizar los resultados de un entrenamiento cardiovagal de 8 semanas valorando la respuesta autonómica, inflamatorios y metabólicas en obesos. Un total de 28 participantes con obesidad fueron estratificados según su HOMA-IR, el grupo sin resistencia a la insulina (NIR) y grupo con resistencia a la insulina (IR). Los participantes se sometieron a un entrenamiento cardiovagal durante 8 semanas. Se consideraron variables metabólicas como la insulina, leptina, TNFa, IL6 y el índice HOMA-IR como también variables de la variabilidad de la frecuencia cardíaca (VFC). Los resultados muestran que en las diferencias de cambio entre el pre y post intervención de los marcadores inflamatorios representaron cambios favorables en IL10 (NIR -0,21 y IR -0,45 pg/ml) y en TNFa (NIR -0,23 y IR -0,51 pg/mL). Mientras que en la VFC sus diferencias de cambio fueron favorables (p=>0,005) SDNN (NIR 3,17 y IR 17,32 ms), RMSSD (NIR 11,45 y IR 23,27 ms) y en LF/HF ratio (NIR 0,74 y IR 2,25 Hz). Se concluye que después de 8 semanas de intervención, el entrenamiento cardiovagal en personas obesas con RI aumentó la modulación parasimpática y atenuó los marcadores inflamatorios.

BackgroundThe incidence of mental health issues in children is increasing worldwide. In Chile, a recent surge in reports of deteriorating mental health among school populations and an increase in complaints related to poor school climate have been observed. Physical activity, specifically active breaks in the classroom, has shown positive effects on children’s health. However, evidence regarding its impact on mental health and school climate in children is limited.ObjectiveThis work outlines the design, measurements, intervention program, and potential efficacy of the “Active Classes + School Climate and Mental Health” project. This project will assess a 12-week program of active breaks through guided videos with curricular content in the school classroom, and its effects on mental health and school climate as its primary indicators. Additionally, it will measure physical activity, physical fitness, motor competence, and academic performance in students aged 6–10 years in the Biobío province, Chile, as secondary indicators. Methodology: A multicenter randomized controlled trial involving 823 students from 1st to 4th grade (6–10 years old), six schools (three intervention and three control) will be conducted in the Biobío region, Chile. Participants belonging to the intervention group will implement video-guided active breaks through the “Active Classes” web platform, featuring curricular content, lasting 5–10 min and of moderate to vigorous intensity physical activity, twice a day, Monday to Friday, over a span of 12 weeks. Expected Results/Discussion: To our knowledge, this will be the first study in Chile to evaluate the effects of incorporating video-guided active breaks with curricular content on mental health variables and school climate in schoolchildren. Thus, this study contributes to the scarce evidence on the effects of video-guided active breaks on mental health variables and school climate in schoolchildren worldwide. Additionally, it will provide crucial information about active teaching methodologies that have the potential to positively contribute to the wellbeing of students, thus addressing the problems of mental health and climate in Chilean schools.

Introducción. El ejercicio físico mejora la salud psicofísica de los adultos mayores. Sin embargo, existen variables sociodemográficas que favorecen o dificultan la práctica deportiva que han sido escasamente investigadas (educación, ingresos, género y estado civil), ni se ha prestado atención a estas variables en relación con los diferentes deportes practicados (gimnasia, actividades acuáticas, yoga, pilates y danza). Objetivo. Por ello, el objetivo de este estudio ha sido conocer el perfil sociodemográfico de los adultos mayores que realizan algún deporte. Procedimiento. Se utilizó la escala de calidad de vida CUBRECAVI y un cuestionario sociodemográfico en una muestra de 358 personas mayores de 60 años (M = 69,66, DT = 4,74). Resultados. Los resultados han mostrado que entre los mayores que hacen gimnasia hay más participantes que tienen menor cualificación académica (p < 0,001), bajos ingresos (p < 0,001); y mujeres (p = 0,003); y que los solteros y divorciados realizan actividades de danza en mayor proporción que otras actividades (p = 0,004). Conclusiones. En conclusión, la actividad deportiva practicada por los adultos mayores está relacionada con el nivel de educación que tienen, los ingresos que perciben, el género y su estado civil. Palabras clave: Personas mayores; envejecimiento; deporte, actividad física; diferencias socioeconómicas; educación; ingresos; género. Abstract. Introduction: Physical exercise enhances the psychophysical well-being of older adults. However, sociodemographic variables that may either facilitate or impede the engagement in physical activities, such as education, income, gender, and marital status, have been insufficiently explored. Furthermore, limited attention has been given to these variables concerning specific physical activities, including gymnastics, aquatic activities, yoga, pilates, and dance. Objective: The aim of this study is to delineate the sociodemographic profile of physically active older adults based on the specific type of physical activity they participate in. Procedure: A sample of 358 individuals aged over 60 years (M = 69.66, SD = 4.74) participated in the study, utilizing the Quality of Life Scale and a sociodemographic questionnaire, specifically the CUBRECAVI. Results: The findings indicate that older adults engaged in gymnastics are more likely to possess lower academic qualifications (p < .001), lower income (p < .001), and be women (p = .003). Additionally, single and divorced individuals participate in dance activities at a higher rate compared to other activities (p = .004).Conclusion: In summary, the choice of physical activity among older adults is associated with their educational level, income, gender, and marital status. Keywords: older adults; aging; physical activity; sport; socioeconomic differences; education; income; gender.

La investigación sobre personas mayores y su experiencia durante la pandemia, considerando si han contraído o no COVID-19, es limitada. Por este motivo, este estudio propuso analizar las dimensiones físicas y emocionales de las personas mayores en el contexto de la pandemia, teniendo en cuenta su historial de infección por el virus. Para llevar a cabo este análisis, se utilizaron la escala de felicidad subjetiva (SHS), el cuestionario de gratitud (CG-6), la escala de Percepción de Salud (SF-12), el cuestionario de Estrés Percibido (PSS), la Evaluación del Dolor (VAS), la Escala de Calidad de Sueño (CS) y la Actividad Física Autoreportada (FAF). Este estudio se basó en una muestra de 71 individuos con edades entre los 55 y 75 años (M= 63.07 años; Sd= 5.49). Los hallazgos revelaron que las personas adultas mayores que habían sido previamente infectados por el virus mostraban una mejor salud mental en comparación con sus pares no infectados (p = .049, d = 0.48). Además, este grupo tenía una mayor tendencia a participar en actividades físicas de manera regular (p = .042; Phi = .250) y experimentaba una mejor calidad de vida. Sin embargo, resulta destacable que los niveles de estrés y felicidad en ambos grupos eran comparables, independientemente de si habían estado expuestos al virus o no. En resumen, este estudio sugiere que las personas mayores que habían superado la infección por COVID-19 presentaban mejores resultados en ciertos indicadores de su bienestar físico y emocional en comparación con aquellos que no habían estado expuestos al virus. Palabras clave: personas mayores, covid-19; salud mental,calidad de vida, actividad física. Abstract. The research on older adults and their experience during the pandemic, considering whether they have contracted COVID-19 or not, is limited. For this reason, this study aimed to examine the physical and emotional dimensions of older adults in the context of the pandemic, considering their history of virus infection. To carry out this analysis, we employed the Subjective Happiness Scale (SHS), the Gratitude Questionnaire (CG-6), the Short Form Health Survey (SF-12), the Perceived Stress Scale (PSS), the Visual Analog Scale for Pain Assessment (VAS), the Sleep Quality Scale (CS), and the Self-Reported Physical Activity Scale (FAF).This study was based on a sample of 71 individuals aged between 55 and 75 years (M= 63.07 years; SD= 5.49). The findings revealed that older adults who had previously been infected by the virus exhibited better mental health compared to their non-infected counterparts (p = .049, d = 0.48). Additionally, this group showed a higher tendency to engage in regular physical activities (p = .042; Phi = .250) and experienced an improved quality of life. However, it is noteworthy that stress and happiness levels in both groups were comparable, regardless of whether they had been exposed to the virus or not. In summary, this study suggests that older adults who had overcome COVID-19 infection demonstrated better outcomes in certain indicators of their physical and emotional well-being compared to those who had not been exposed to the virus. Keywords: older people, covid-19; mental health, quality of life, physical activity.

Abstract Objective: To investigate the association between a lifestyle score and all-cause mortality in the Chilean population. Design: Prospective study. Settings: The score was based on seven modifiable behaviours: salt intake, fruit and vegetable intake, alcohol consumption, sleep duration, smoking, physical activity and sedentary behaviours. 1-point was assigned for each healthy recommendation. Points were summed to create an unweighted score from 0 (less healthy) to 7 (healthiest). According to their score, participants were then classified into: less healthy (0–2 points), moderately healthy (3–4 points) and the healthiest (5–7 points). Associations between the categories of lifestyle score and all-cause mortality were investigated using Cox proportional hazard models adjusted for confounders. Nonlinear associations were also investigated. Participants: 2706 participants from the Chilean National Health Survey 2009–2010. Results: After a median follow-up of 10·9 years, 286 (10·6 %) participants died. In the maximally adjusted model, and compared with the healthiest participants, those less healthy had 2·55 (95 % CI 1·75, 3·71) times higher mortality risk due to any cause. Similar trends were identified for the moderately healthy group. Moreover, there was a significant trend towards increasing the mortality risk when increasing unhealthy behaviours (hazard ratio model 3: 1·61 (95 % CI 1·34, 1·94)). There was no evidence of nonlinearity between the lifestyle score and all-cause mortality. Conclusion: Individuals in the less healthy lifestyle category had higher mortality risk than the healthiest group. Therefore, public health strategies should be implemented to promote adherence to a healthy lifestyle across the Chilean population.

Existe información limitada respecto a la respuesta de la frecuencia cardiaca (FC) a partir de fórmulas predictivas y prueba de ejercicio real entre adultos con hipertensión arterial (HTA) y normotensos, así como sobre las similitudes o diferencias vasculares entre muestras de diferente control de la presión arterial. El objetivo de este estudio fue describir y comparar la frecuencia cardiaca durante el ejercicio entre adultos con HTN y normotensos, así como describir parámetros de función endotelial y vasculares. Se realizó un estudio clínico descriptivo con 64 adultos (hombres y mujeres) que fueron divididos en tres grupos: hipertensión arterial (HTN n=26), presión arterial elevada (Ele n=16), o normotensos control (CG n=22). Los participantes se sometieron a una prueba de ejercicio, en la que se midió la FC (variable principal) y parámetros vasculares secundarios (clasificación percentil de la velocidad de la onda del pulso (%ILEPWVba), grosor máximo de la íntima-media carotídea (cIMTmax) y edad arterial entre otras. En la etapa 2 del test (50-100 vatios), el grupo HTN mostró una FC significativamente mayor vs. el grupo GC (+14 latidos/min), y vs. el grupo Ele (+15 latidos/min), ambos p

Positional cranial deformities are associated with prematurity evolving during the first 2 years of life due to the malleable characteristics of the skull, the first year being the main/primary therapeutic window for intervention. The objectives were (a) to describe health characteristics, peri- and postnatal pathologies, and positional cranial deformities in infants enrolled in an early intervention program and (b) to analyze the effects of a parent education-based intervention program on positional cranial deformity in premature infants. A quantitative, analytical, longitudinal study was conducted. It included 103 premature infants enrolled in an early intervention program (EIP) during the year 2017, all under 4 months of corrected age, to whom a parent education-based intervention program was applied. Cranial circumference, cranial width, diagonals, and anteroposterior diameter were measured, and the cranial asymmetry index (CAI) and cephalic index (CI) were calculated at baseline and during two subsequent evaluations separated by a 3-month period. The main results showed that 75.7% of the infants belonged to a very premature gestational age category, and 57.3% had an adequate weight for gestational age. The most frequent pathologies were premature jaundice, premature anemia, and hyaline membrane disease. The most frequent positional cranial deformity was plagiocephaly. The parent education-based intervention program resulted in (1) a significant decrease in the CAI and a significant increase in the IC, (2) plagiocephalies: an increase in the mild category and a decrease in the moderate + severe categories, (3) brachycephalies: a decrease in the absence category and an increase in the moderate + severe category, and (4) dolichocephalies: an increase in the absence category and a decrease in the mild category. In conclusion, the recommended first line of intervention was not enough for this population, and future studies should support the development of national clinical guidelines, where education is complemented with other therapeutic measures.

Background and Objectives: Although there is strong evidence of the positive effects of physical exercise on health, adherence to face-to-face exercise programs in the adult population is low, identifying several barriers that hinder their practice. There is research that demonstrates the viability of physical exercise programs with the use of Mobile Health in Ecological Momentary Assessment (EMA) mode, which contributes to overcoming many reported barriers. To synthesize the methodological characteristics and health effects of physical exercise programs based on mobile health in EMA modality in adults in developing countries. Materials and Methods: This systematic review was conducted according to guidelines established by the PRISMA statement in APA PsycArticles and CINAHL databases by EBSCOhost, Cochrane Library, PubMed, and Web of Science for articles published between 2008 and March 2024. Results: Telephone counseling on clinical–behavioral factors is believed to reduce morbidity and mortality in developed countries, but this aspect is not explored in developing countries. We included nine randomized controlled trials with a total of 4394 male and female participants aged 18 to 60 years. The interventions were mainly carried out by text messages, lasting between 20 to 80 min per session, 3 to 5 days per week, and most were carried out over 12 months. The interventions on the variables of physical activity, nutrition, and medical assessments showed significant effects, and variables such as quality of life and anthropometric measurements were not significant in most studies. Conclusions: This systematic review included studies from different developing countries, the most common diseases being diabetes, overweight, obesity, and hypertension. All the studies used mobile devices as the technology, finding a profile of the adults studied, as well as the characteristics of exercise programs based on mobile health in EMA modality.

Antecedentes: Aunque se ha documentado la eficacia de las intervenciones vía mobile health (mHealth) para aumentar el ejercicio físico, existe evidencia limitada sobre la motivación, las barreras y los beneficios asociados a la práctica de ejercicio físico en este tipo de intervenciones mHealth. Objetivo: Examinar las diferencias de motivación, barreras y beneficios entre el ejercicio físico vía mHealth y presencial. Método: Estudio preexperimental en 37 adultos (96,5% mujeres, 43 ±10,5 años) del Biobío, Chile, quienes participaron de una intervención de ejercicio físico vía mHealth. Se utilizó el Cuestionario de la Regulación de la Conducta en el Ejercicio (BREQ-3), y la Escala de Beneficios/Barreras para el Ejercicio (EBBS). Resultados: Luego de la intervención, el grupo de ejercicio físico mHealth presentó mayor puntaje de motivación de tipo regulación externa (3,25 ±3,79 v/s 1,08 ±1,60; t(33,676)= 2,434, p= 0,020, d= 0,676), un menor puntaje de motivación de tipo integrada (3,25 ±3,79 v/s 1,08 ±1,60; t(33,676)= 2,434, p= 0,020, d= 0,676), y un menor índice de autodeterminación en la práctica de ejercicio físico (45,25 ±26,54 v/s 67,38 ±19,61; t(35)= - 2,635, p= 0,012, d= 0,908) que el grupo de ejercicio físico presencial. No se observaron diferencias significativas en las barreras y beneficios para la práctica de ejercicio físico. Conclusiones: El ejercicio vía mHealth generó una mayor motivación externa y una menor motivación integrada en comparación con el ejercicio presencial. Estos hallazgos respaldan el potencial de la tecnología mHealth para promover la motivación en la actividad física y superar las barreras percibidas. Palabras clave: ejercicio; mobile health; motivación; barreras y facilitadores; intervención. Abstract. Background: Although the efficacy of interventions via mobile health (mHealth) to increase physical exercise has been documented, there is limited evidence on the motivation, barriers and benefits associated with practicing of physical exercise in this type of mHealth intervention. Objective: To examine the differences in motivation, barriers and benefits between the practice of physical exercise via mHealth and in person. Method: Pre-experimental study in 37 adults (96.5% women, 43 ±10.5 years old) from the Biobío, Chile, who participated in a physical exercise intervention via mHealth. The Exercise Behavior Regulation Questionnaire (BREQ-3), and the Exercise Benefits/Barriers Scale (EBBS). Results: After the intervention, the mHealth physical exercise group presented a higher external regulation type motivation score (3.25 ±3.79 v/s 1.08 ±1.60; t(33.676)= 2.434, p= 0.020, d= 0.676), a lower integrated motivation score (3.25 ±3.79 v/s 1.08 ±1.60; t(33.676)= 2.434, p= 0.020, d= 0.676), and a lower index of self-determination in the practice of physical exercise (45.25 ±26.54 v/s 67.38 ±19.61; t(35)= -2.635, p= 0.012, d= 0.908) than the group face-to-face physical exercise. No significant differences were observed in the barriers and benefits for the practice of physical exercise. Conclusions: The exercise via mHealth generated greater external motivation and less integrated motivation compared to the face-to-face exercise. These findings support the potential of mHealth technology to promote physical activity motivation and overcome perceived barriers.

Although benefits have been reported from the practice of physical activity in children with autism spectrum disorder (ASD), to a lesser extent the characteristics of the programs carried out in the school context and their effects on health are known. The objective of this review was to characterize school based physical activity programs and their effects on the health of schoolchildren with ASD. The review was carried out in accordance with the PRISMA statement in the databases, Medline and PsycINFO, between the years 2010 to 2023. A total of 20 articles were analyzed. A total sample of 683 schoolchildren with ASD (x̄=10.5 years and 73.1% male) were included. Schoolchildren with ASD had 98.1% adherence to the programs. The school based physical activity programs were mainly based on aerobic exercises, such as walking, jogging, running, and cycling (45% of the articles) with a duration between 10-16 weeks (55% of the articles), with a frequency of 2-3 times a week (60% of the articles) and with 60-minute sessions (45%). On the other hand, the most studied variables were language and motor skills (60% of the articles) and psychosocial and cognitive function (50% of the articles); together with the variables of physical and nutritional activity, these were where a higher percentage of articles with positive effects were found. The findings suggest a profile of schoolchildren with ASD and the main characteristics of school based physical activity programs in schoolchildren with ASD in terms of their extension, frequency, duration, intensity, location and provider as well as the variables most frequently evaluated and with the greatest positive effects. Keywords: Exercise; Autism Spectrum Disorder; ASD; Cognition; Physical Activity; Scoping Review.

Materiales y método: 14 personas mayores (x̄=74 años), sometidas a un programa de kinesiterapia/fisioterapia/ terapia física (TF) a través de TR por un periodo de 12 semanas. El grupo control recibió intervención educativa a través de un cuadernillo de actividad física que debieron desarrollar de forma autónoma, con supervisión telefónica semanal; mientras que el grupo experimental recibió 20 sesiones de TF por video llamada mediante aplicación WhatsAppTM. Ambos grupos fueron evaluados pre y post intervención con escala índice de Barthel (IB) y el número de caídas mediante cuestionario de la valoración geriátrica integral (VGI). Resultados: El grupo experimental aumentó el puntaje del IB (↑3,6), mientras que el grupo control disminuyo este puntaje (↓6,9). Ambos grupos disminuyen el número de caídas, sin encontrar diferencias entre grupos. Al comparar ambos grupos, las personas mayores sometidas a un programa de TF a través de TR presentaron mejoras significativamente mayores en el IB que el grupo control (p

Introducción: El aumento del uso de teléfono celular y la baja actividad física en universitarios se han asociado a un bajo rendimiento académico. Objetivo: Analizar la relación entre tiempo de uso del teléfono celular, el nivel de actividad física y rendimiento académico en estudiantes universitarios. Materiales y métodos: Estudio de alcance correlacional y temporalidad longitudinal. Participaron 36 estudiantes universitarios, a quienes se evaluó durante un semestre, el tiempo que destinaron al uso de teléfono celular, a través de la aplicación “Moment” y la actividad física mediante la aplicación “Pacer”. Se registró el rendimiento académico con el promedio de notas. Resultados: Durante el semestre, los hombres realizaron mayor actividad física y utilizaron por mayor tiempo el teléfono. En periodos de evaluación, las mujeres tuvieron mayor actividad física y menor uso del teléfono celular (p=0,019 y p=0,033, respectivamente). Además, los hombres que tuvieron mejores notas promedio hacían un menor número de pickups diarios (p=0,032). Conclusiones: Los hombres universitarios son físicamente más activos y usan más el celular durante el semestre, aunque en periodo de evaluaciones las mujeres tienden a ser más activas y usar menos tiempo su celular. Los universitarios que usan menos el teléfono celular tienen mejor rendimiento académico.

This scoping review synthesizes the evidence of the psychological outcomes of physical activity interventions in the classroom in children aged 6 to 12 years and describes the characteristics of the physical activity interventions implemented. We systematically searched in databases MEDLINE, SCOPUS, PsycINFO, ScienceDirect, Web of Science and SciELO, of randomized control trials published up to July 2020 of classroom-based physical activity interventions with children´s psychological health variables as outcomes. Sixteen trials (14,877 participants) with children aged 6 to 12 years were included. There were significant effects on several indicators of: a) psychological health outcomes: well-being, self-esteem, body image satisfaction b) self-efficacy and motivation to physical activity and c) behavior inside the classroom: self-regulation, bullying and disruptive behavior. The most effective interventions are those that included physical activity integrated into the curriculum 2-5 times a week, in sessions between 4' to 10', implemented mainly by the classroom teacher and with audio-visual support. However, the heterogeneity in program designs did not allow definitive conclusions. While psychological outcomes are mainly primary outcomes in the interventions studied, more evidence is required on other indicators of psychological health such as mental health symptoms. In addition, studies need to employ objective measures of physical activity to a better comprehension of their effects on psychological health of schoolchildren.

Introducción: La incontinencia urinaria por esfuerzo (IUE) tiene una alta prevalencia en mujeres adultas, afectando variables psicológicas, sociales y funcionales como la disminución de capacidad de equilibrio, debido a una escasa contribución en los movimientos del tronco hacia una corrección postural. Objetivo: Determinar los efectos de un programa basado en ejercicio muscular de piso pélvico y educación sobre el equilibrio estático y la calidad de vida en mujeres con IUE. Materiales y métodos: Participaron 18 mujeres con IUE durante 12 semanas en 10 sesiones de ejercicio muscular de piso pélvico y educación (hábitos de higiene, micción, ingesta de líquidos). Pre y post-intervención se evaluó equilibrio estático mediante oscilografía postural y calidad de vida mediante el International Consultation on Incontinence Questionnaire Short-Form (ICQ-SF). Los datos fueron analizados con la prueba no paramétrica de Wilcoxon. Resultados: Se encontró una disminución significativa en el área de desplazamiento del centro de presión en el subtest ojos abiertos (p=0,027) y en el subtest ojos cerrados (p=0,006). Disminuyó la sintomatología asociada a IUE (p=0,0001). Conclusiones: Pos-intervención mejora equilibrio estático y calidad de vida, confirmando los efectos positivos de este programa que pueden servir de orientación a profesionales de la salud que trabajan con mujeres con IUE.

La mejora de la fuerza de las extremidades inferiores tiene implicancias significativas en la funcionalidad de las personas mayores. El objetivo del estudio fue evidenciar el efecto del entrenamiento pliométrico (EP) sobre los parámetros de velocidad de desplazamiento, fuerza resistencia y explosiva en mujeres mayores sedentarias. 30 mujeres entre 60-75 años fueron intervenidas en un programa de 4 semanas, 3 veces por semana divididas en Grupo Experimental (GE) y Grupo Control (GC). Fueron evaluadas pre y post intervención con el test velocidad en 10 metros, potencia mediante la prueba CMJ y la evaluación del Test 30s CST. Se analizaron las variables mediante la prueba estadística U de Mann-Whitney. Resultados: El EP mejoró en forma significativa la velocidad de desplazamiento (p

Resumen: Objetivo: Identificar la asociación entre salud oral y sospecha de deterioro cognitivo en personas mayores chilenas. Método: Estudio transversal con 1826 participantes ≥60 años de la Encuesta Nacional de Salud de Chile, 2016-2017. La salud oral fue evaluada por el número de dientes, la presencia de caries, el uso de prótesis dental y el autorreporte de salud oral y dolor en la cavidad oral. La sospecha de deterioro cognitivo fue evaluada mediante el Mini-Mental State Examination (MMSE). Se empleó regresión logística y lineal, ajustada por variables sociodemográficas y de estilos de vida. Resultados: En comparación con personas sin sospecha de deterioro cognitivo, aquellas con sospecha de deterioro cognitivo presentaron cinco dientes menos (13,4 vs. 8,5 dientes), diferencia muy superior en mujeres que en hombres, y mayor frecuencia de dolor oral. El edentulismo y el menor número de dientes se asociaron a mayor probabilidad de sospecha de deterioro cognitivo, asociaciones que no se mantuvieron en modelos ajustados. El dolor oral se asoció a mayor probabilidad de sospecha de deterioro cognitivo (odds ratio: 1,99; intervalo de confianza del 95% [IC95%]: 1,09-3,63). Por cada diente adicional se observó un aumento del 2% (IC95%: 0,01-0,05) en la puntuación del MMSE. Conclusiones: La mala salud oral, en particular la pérdida de dientes y la presencia de dolor, se asociaron con deterioro cognitivo en personas mayores chilenas. Abstract: Objective: To identify the association between oral health and suspected cognitive impairment in older adults in Chile. Method: Cross-sectional study including 1826 people ≥60 years who participated in the National Health Survey of Chile, 2016-2017. Oral health was evaluated by the number of teeth, presence of caries, use of dental prostheses, self-reported oral health, and pain and/or discomfort in the oral cavity. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE). The association was evaluated by logistic and linear regression, adjusted for sociodemographic and lifestyle variables. Results: Compared with people without suspicion of cognitive impairment, people with suspected impairment had five fewer teeth (13.4 vs. 8.5 teeth), a much higher difference in women than in men, and a higher frequency of oral pain. Edentulism and fewer teeth were associated with a higher likelihood of suspected cognitive impairment, associations that were not maintained in adjusted models. Oral pain was associated with a higher likelihood of suspected impairment even in the most adjusted model (odds ratio: 1.99; 95% confidence interval [95%CI]: 1.09-3.63). In linear models, an increase of 2% (95%CI: 0.01-0.05) in the MMSE score was observed for each additional tooth. Conclusions: Poor oral health, particularly tooth loss and the presence of pain, was associated with cognitive impairment in older adults in Chile.

Inclusive education acknowledges and values the capabilities and needs of every student. Exploring their perceptions of psychosocial variables and academic performance can significantly enhance inclusive practices and improve overall school performance, particularly for students with special educational needs (SEN). This study aimed to assess mental health, subjective well-being, and academic performance among students in the school inclusion program (SIP) and those not in the program. Conducted as an analytical cross-sectional study, this research endeavor entailed the utilization of a probabilistic, stratified sampling approach designed to ensure community representativeness. The study sample encompassed a cohort of 730 school students aged between 10 and 15 years (M = 12; SD = 1.3 years) representing five different public schools in the Biobío region, all integrating SIPs into their educational structure. Student assessments involved the Rosenberg Self-Esteem Scale, Beck Anxiety Inventory, and Subjective Happiness Scale. Additionally, their academic performance was measured based on grade point averages (GPAs) and final accumulated grades in language and literature as well as mathematics. Students enrolled in the SIP obtained lower scores in the self-esteem, anxiety, and happiness assessments along with poorer academic performance compared to their non-SIP counterparts. Consequently, students participating in the SIP displayed lower levels of mental health and subjective well-being along with inferior academic performance in contrast to their non-participating counterparts. These findings are alarming, as SIP implementation is a key strategy for promoting inclusive education in Chile and enhancing the learning of all students, especially those with SEN.

The Mediterranean diet stands as a widely acknowledged and health-promoting dietary pattern, renowned for its notable linkage to the mitigation of noncommunicable chronic maladies. Nonetheless, the existing body of evidence concerning the potential interrelation between sleep hygiene and this dietary regimen remains circumscribed. The main objective was to determine the association between sleep hygiene and adherence to the Mediterranean diet in Chilean schoolchildren from rural public schools in southern Chile. A non-experimental study was carried out, with an analytical, cross-sectional design. A total of 265 students (56.6% women, mean age 13.5 ± 1.8) from a rural community in southern Chile were recruited. Sleep habits were evaluated using Section 6 of the Life Habits and Adolescence Questionnaire, Sleep and Rest, and adherence to the Mediterranean diet was assessed with the KIDMED Mediterranean Diet Adherence Questionnaire. The main results indicated that 52.8% of schoolchildren need to improve adherence to the Mediterranean diet and 16.6% have a low-quality Mediterranean diet. A high percentage of schoolchildren have behaviors related to poor sleep hygiene (going to bed late (46%), waking up tired and wanting to continue sleeping (63.8%), and having problems falling asleep (42.6%)). Schoolchildren who got up after 8:30 a.m., those who fell asleep after midnight, upon conducting a comparative analysis of the students based on their sleep patterns, those who woke up tired and those who had trouble falling asleep had a lower level of adherence to the Mediterranean diet compared to schoolchildren who got up earlier than 8:30 a.m., fell asleep before midnight, did not wake up tired, and those who did not find it difficult to fall asleep, respectively. In conclusion, having poor sleep patterns including difficulties in both awakening and falling asleep are associated with less adherence to the Mediterranean diet in schoolchildren from rural public schools in southern Chile. Monitoring these variables and promoting healthy lifestyle habits within the educational community are essential measures.

Fundamento: una intervención basada en ejercicio multicomponente favorecería la funcionalidad. Sin embargo, son escasos los estudios locales, en Chile, que los han utilizado.Objetivo: determinar los efectos del ejercicio multicomponente en la disminución del riesgo de caída y riesgo de deterioro cognitivo, la mejora del equilibrio, fuerza muscular, capacidad funcional y calidad de vida en personas mayores que viven en comunidad.Métodos: estudio preexperimental pre-post sin grupo control. La muestra fue intencionada (n=17; 47,1 % mujeres; 70 años de mediana). Se aplicó un plan de ejercicio multicomponente durante nueve semanas. Pre y post ejercicio se evaluó equilibrio dinámico con el test Timed Up and Go, equilibrio estático con un oscilógrafo postural y la prueba de Estación Unipodal, fuerza muscular con el test de Sentarse y Levantarse, capacidad funcional con el test de Marcha 6 Minutos, calidad de vida con el Cuestionario SF-36 y sospecha de deterioro cognitivo con el Mini Mental State. Para determinar diferencias pre-post ejercicio se aplicó la prueba de Wilcoxon.Resultados: después de los ejercicios se observó un mejor rendimiento en las pruebas: Timed Up and Go (p=0,004), Estación Unipodal (p=0,023 pierna derecha, p=0,005 pierna izquierda), Sentarse y Levantarse (p=0,014), Marcha de 6 Minutos (p=0,006) y en el Cuestionario SF-36: dolor corporal (p=0,003), salud mental (p=0,000) y puntaje total (p=0,002).Conclusiones: un programa de ejercicio multicomponente de nueve semanas logró disminuir el riesgo de caídas, mejorar equilibrio, fuerza muscular, capacidad funcional y calidad de vida de personas mayores que viven en comunidad.

Background: Childhood obesity has tripled, reaching critical levels of malnutrition. This factor is directly associated with a poorer health-related quality of life of the child and adolescent population. This article presents the study protocol of the project “Strong schoolchildren with a healthy lifestyle” (EF-Salud), which seeks to analyze the effects of a multicomponent program based on muscle strength exercises, sleep nutritional recommendations, and the use of screens in Chilean educational centers with extremely cold weather. Methods: The study protocol of a randomized controlled trial with a pre- and post-test conducted according to the CONSORT statement is reported. The total sample (n = 144) will be schoolchildren from six different school years, four of which will perform an intervention and two control. Intervention group 1 (from two different school years) will receive a muscular strength exercise program in the classroom once a day from Monday to Friday for six months and nutritional, sleep, and use of screens recommendations once a week. Intervention group 2 (from two different school years) will receive a program of nutritional, sleep, and use of screens recommendations once per week for six months. The control group (from two different school years) will carry out their usual school day in relation to physical education classes. Before and after the intervention, the investigators will evaluate the cardiovascular risk, physical condition, and lifestyle related to sleep and use of screens. Expected results: The schoolchildren in intervention group 1 will obtain significant results in increased strength, decreased cardiovascular risk, improved sleep habits, and fewer hours of screen use compared to the other two groups.

Zapata Lamana, R., Fuentes Figueroa, V., Reyes Molina, D., Geisse Zárate, A. E. y Cigarroa, I. (2021). Características metodológicas en el estudio del compromiso hacia la práctica de actividad física y ejercicio en población general: una revisión sistemática. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(1), 1-23. Aunque la literatura sobre el compromiso deportivo en población deportista es extensa, se requiere profundizar sobre el compromiso hacia la práctica de actividad y ejercicio físicos en la población general. El objetivo del estudio fuesintetizar las características metodológicas de los artículos que han estudiado el compromiso hacia la práctica de actividad y ejercicio físicos en la población general. Se desarrolló una revisión sistemática siguiendo la declaración PRISMA. Se realizaron búsquedas electrónicas en las bases de datos PsycINFO y Medline desde 2009 al 2019. Un total de 14 artículos fueron elegidos, principalmente con diseños transversales. La población más estudiada fue de estudiantes universitarias mujeres, sin condición clínica. Todos los instrumentos utilizados para evaluar el compromiso hacia la actividad física y ejercicio estaban escritos en inglés, en su mayoría aplicados en Estados Unidos. Utilizaban una escala Likert con alta fiabilidad. Las principales variables asociadas a la evaluación del compromiso fueron la edad, género, origen étnico, nivel educativo y económico, nivel de actividad física, comportamiento, patologías alimentarias e índice de masa corporal y variables sociocognitivas, como autoeficacia, apoyo social, barreras y beneficios percibidos para la realización de la actividad física. Esta revisión entrega un perfil de la población en quien se evalúa el compromiso hacia la actividad física y ejercicio, los instrumentos utilizados y variables asociadas, lo que actualiza el conocimiento existente sobre el compromiso hacia la actividad física y ejercicio en la población general.

Aims: To verify a Brazilian Jiu-Jitsu fighter profile studied in the literature and to characterize the variables, techniques and instruments for measuring sports performance. Methods: The review was carried out according to the declaration criteria PRISMA, considering studies between the years 2010 and 2020 in the SportDiscus, PubMed/Medline, SCOPUS, LILACS, Dialnet and SCIELO. Results: A total of 51 studies were chosen, mostly of Brazilian origin (82.4%). The total sample was integrated by 1,493 fighters (98% men), with an average age of 27.1 years. The most assess variables were the physiological (24 studies) and the physical (13 studies). Of them, the most analyzed were the lactate and grip force, respectively. The assessment instruments most used were the Borg Rating of Perceived Exertion for the physiological variables (13 studies), the dynamometry for the physical variables (13 studies), and the weight scale for anthropometric and nutritional variables (15 studies). Conclusions: It has been generated a Brazilian Jiu-Jitsu fighter profile. The most frequently studied variables were the physiological and physical. The most assessment instrument used were the weight scale, dynamometry and Borg Rating of Perceived Exertion. Moreover, there are few studies that perform measurements in real time, in female fighters, in Brazilian Jiu-Jitsu fighters and who report the fighter style. Resumen: Objetivos: Verificar un perfil de luchador de Jiu-Jitsu brasileño estudiado en la literatura y caracterizar las variables e instrumentos utilizados para valorar el rendimiento deportivo. Metodología: La revisión se realizó de acuerdo con los criterios de declaración PRISMA, considerando estudios entre los años 2010 y 2020 en el SportDiscus, PubMed / Medline, SCOPUS, LILACS, Dialnet y SCIELO. Resultados: Se eligieron un total de 51 estudios, en su mayoría de origen brasileño (82,4%). La muestra total estuvo integrada por 1.493 combatientes (98% hombres), con una edad promedio de 27,1 años. Las variables más evaluadas fueron las fisiológicas (24 estudios) y las físicas (13 estudios). De ellos, los más analizados fueron el lactato y la fuerza de agarre, respectivamente. Los instrumentos de evaluación más utilizados fueron el Borg Rating of Perceived Esfuerzo para las variables fisiológicas (13 estudios), la dinamometría para las físicas (13 estudios) y la escala de peso para las variables antropométricas y nutricionales (15 estudios). Conclusiones: Se ha generado un perfil de luchador de Jiu-Jitsu brasileño. Las variables más estudiadas fueron las fisiológicas y físicas. Los instrumentos de evaluación más utilizados fueron la escala de peso, la dinamometría y el índice de Borg de esfuerzo percibido. Además, existen pocos estudios que realicen mediciones en tiempo real, en luchadoras femeninas, en luchadoras de Jiu-Jitsu brasileñas y que reporten el estilo de luchadores.

RESUMEN Objetivos: Determinar si la velocidad de marcha lenta se asocia a un mayor riesgo de deterioro cognitivo en personas mayores de 60 años, sanas, que viven en la comunidad, e investigar si esta asociación es modificable según niveles de actividad física y tiempo que permanecen sentados. Métodos: Estudio correlacional, transversal y retrospectivo. Se incluyeron 1082 personas mayores de 60 años de la Encuesta Nacional de Salud (ENS) 2009-2010 de Chile. La velocidad de la marcha (normal o lenta) fue autorreportada y el riesgo de deterioro cognitivo se evaluó con el cuestionario Mini-Mental State Examination. Las variables sociodemográficas y de estilos de vida se obtuvieron mediante la aplicación de cuestionarios validados en la ENS 2009-2010. Adicionalmente se evaluó el estado nutricional a través del índice de masa corporal. Resultados: Las personas mayores que presentaban una menor velocidad de marcha evidenciaron un mayor riesgo de presentar deterioro cognitivo en comparación con aquellos que caminan a velocidad de paso normal (OR:1,62 [IC95%:1,06;2,54], p=0,036). Esta asociación fue independiente de factores sociodemográficos, obesidad, tiempo sedente, actividad física y estilos de vida. Conclusión: Las personas mayores que reportaron caminar a un paso más lento que sus pares de la misma edad presentan un mayor riesgo de deterioro en comparación con aquellos que tienen una velocidad de la marcha normal. La probabilidad de deterioro cognitivo en personas mayores con marcha lenta aumenta en aquellas que no cumplen con las recomendaciones de actividad física dadas por la Organización Mundial de Salud o pasan más de 4 horas diarias en actividades sedentarias. Estos resultados refuerzan la idea de que la velocidad de la marcha podría ser usada como una herramienta de detección de riesgo de deterioro cognitivo en personas mayores.

Objetivo: Analizar las características metodológicas y de investigación, los antecedentes del sujeto de estudio y de las evaluaciones e intervenciones de las tesis de pregrado de la carrera de kinesiología en una universidad chilena durante los años 2010 - 2018.Materiales y métodos: Se analizaron 91 tesis; para su análisis se utilizó un instrumento validado que se organizó en tres grandes categorías: a) características metodológicas y de investigación, b) antecedentes del sujeto de estudio y c) antecedentes de las evaluaciones e intervenciones, y se registró un total de 38 ítems.Resultados: Se reportó que las tesis mayoritariamente las realizan dos estudiantes tesis-tas, en conjunto con un guía con grado licenciado, presentan un alcance descriptivo, diseño no experimental, temporalidad transversal, con muestras pequeñas, no probabilísticas, por conveniencia, utilizando cuestionarios y/o encuestas para medir parámetros de actividad y condición físicas principalmente en las áreas respiratoria y traumatológica. Las tesis cumplen con la estructura de un reporte científico, aun cuando un gran porcentaje de ellas tiene referencias poco actualizadas y no incluyen datos de aprobación del comité de ética. Los sujetos de estudio principalmente eran jóvenes y adultos pertenecientes a centros educativos de enseñanza básica, media, universitaria o a una red de atención de salud pública que presentaban algún diagnóstico médico de enfermedad cardiometabólica.Conclusión: Este estudio reveló información valiosa respecto a cómo se ha llevado a cabo la formación investigativa de esta carrera de la salud, identificó áreas de conocimiento, poblaciones y condiciones de salud poco exploradas y los tratamientos usados frecuentemente.

In Latin America, various experiences that promote active aging are recognized, and can be replicated in various communities, as strategies aimed at a better quality of life. The objective of this review is to identify interventions or recommendations aimed at promoting active aging in Ibero-American countries. The search for evidence was carried out in publications of articles available between 2010 and 2019, using the Medline, Scopus, Scielo, Science-Direct, Virtual Health Library, MEDES and Dialnet databases. Recommendations and experiences carried out for this age group include classic activities such as physical activity or health education workshops, but also cultural, tourist, intergenerational, cognitive strengthening actions, intersectoral activities, life stories, place of residence or use of information technologies. Future promotional experiences for this age group should be planned with an integrating perspective of activities that promote healthy living through creation, culture and healthy living.

El estudio de la relación entre el desarrollo de patrones motores y los niveles de actividad física en la infancia, ha tomado un renovado interés con el objetivo de reorientar las prácticas en este grupo etario. El objetivo de la presente investigación fue comparar el efecto de una intervención de 12 semanas, mediante la ejecución de circuitos de actividad física, sobre el rendimiento motor en preescolares, la muestra seleccionada fue un grupo de niños y niñas de entre 4-6 años, que para efectos de la investigación se dividieron en dos grupos de acuerdo a su estado nutricional: normopeso (n=12) y sobrepeso/obesidad (n=9).Corresponde a un estudio cuantitativo, en el que se evaluó IMC/edad, circunferencia de cintura y rendimiento motor. De acuerdo con los resultados se logró evidenciar que existen mejoras significativas en el rendimiento motor del grupo normopeso, específicamente en el equilibrio, salto y carrera y en el grupo con sobrepeso/obesidad, solo hubo una mejora en la carrera. En conclusión, una intervención de actividad física, mediante circuitos, mejoró el rendimiento motor en la muestra de preescolares, principalmente en el grupo con estado nutricional normal. Abstract: The study of the relationship between the development of motor patterns and levels of physical activity in childhood has taken a renewed interest with the aim of reorienting practices in this age group. The objective of this research was to compare the effect of a 12-week intervention, through the execution of physical activity circuits, on motor performance in preschoolers, the selected sample was a group of boys and girls between 4-6 years old, that for research purposes were divided into two groups according to their nutritional status: normal weight (n = 12) and overweight / obesity (n = 9). It corresponds to a quantitative study, in which BMI / age, circumference waist and motor performance. According to the results, it was possible to show that there are significant improvements in motor performance in the normal weight group, specifically in balance, jumping and running and in the overweight / obese group, there was only one improvement in running. In conclusion, a physical activity intervention, using circuits, improved motor performance in the preschool sample, mainly in the group with normal nutritional status.

There is a discrepancy about the characteristics and effects of exercise-based programs in older cancer survivors (OCS). Therefore, this scoping review aimed to identify the characteristics and effects of physical activity programs in OCS health. This scoping review followed the PRISMA guidelines and included randomized clinical trials and clinical trials from MEDLINE by PubMed, Scopus, Scielo, and PEDro, published between 2010 and 2020. Results suggest that physical programs were carried out in health centers (54.2%) and were based on physical exercise (74.4%). The length of the exercise interventions was between 3–6 months (87.5%) was performed 2–3 times per week (73.1%) with a duration between 20–60 minutes (78.2%) and was run by health professionals (94.4%). The health outcomes with the most positive effects were physical activity, depression, and quality of life. In conclusion, physical programs for OCS based on aerobic exercises are safe and could be a therapeutic strategy to improve different health markers in OCS. Resumen. En la literatura existe discrepancia sobre las características y los efectos de los programas basados en el ejercicio físico en sobrevivientes de cáncer (SC) de edad avanzada. Por lo tanto, esta revisión de alcance tuvo como objetivo identificar las características y los efectos de los programas de actividad física en la salud de personas SC de edad avanzada. Esta revisión de ensayos clínicos aleatorizados y ensayos clínicos, se realizó considerando las siguientes bases de datos: MEDLINE (de Pubmed), Scopus, Scielo y PEDro, entre los años 2010 y 2020. Los resultados indican que los programas de ejercicio se realizaron en centros de salud (54.2%), y se basaron en ejercicio físico principalmente (74.4%). La extensión de las intervenciones físicas fue entre 3–6 meses (87.5%), se realizaron 2–3 veces por semana (73.1%) con una duración entre 20–60 minutos, y fueron dirigidas por profesionales de salud (94.4%). El impacto sobre la salud con mayores efectos positivos fueron la actividad física, la depresión y la calidad de vida. En conclusión, los programas de ejercitación física para personas SC en edad avanzada, basados en ejercicios aeróbicos son seguros y podrían ser una estrategia terapéutica para mejorar diferentes variables de salud en este grupo de personas.

This review describes the adherence characteristics and reasons for abandonment physical exercise-based interventions in older adults in Latin America. This scoping review was conducted in accordance with the PRISMA statement. Articles were searched in MEDLINE by PubMed, ELSEVIER by SCOPUS and SciELO. The MeSH terms "Exercise", Exercise Therapy" and "Aged" were used between 2015 and 2020. We searched for articles in Spanish, English, and Portuguese carried out in people aged 65 years and over.101 out of 4,642 randomized controlled trials (RCT) were included. A total sample of 5,013 older adults (79% women), with an average age of 68.2 years started their studies and 4,312 finished it, presenting an adherence to the interventions of 86%. Most of the studies were carried out in healthy older adults, in places enabled for the practice of physical activity, in charge of a physical activity professional, and the interventions were performed carried out through group therapeutic exercise. No article reported information on the minimum time of participation to the session to be considered as carried out. Only 30% of the articles reported the minimum participation of older adults in the intervention to include them in the study analysis, and 21% reported the average number of sessions attended to the intervention. The main reasons for abandonment were personal causes unrelated to the intervention. Only 5% of the articles reported injury of one of the participants (in two of them the injury was related to the intervention applied). This review characterized the physical exercise programs in older adults in Latin America, as well the adherence characteristics and the main reasons for abandonment to physical exercise-based interventions, by summarizing available evidence derived from RCTs. Resumen. Esta revisión describe las características de adherencia y motivos de abandono de las intervenciones basadas en ejercicio físico en adultos mayores en América Latina. Esta revisión de alcance se realizó de acuerdo con la declaración PRISMA. Los artículos fueron buscados en MEDLINE por PubMed, ELSEVIER por SCOPUS y SciELO. Los términos MeSH "Ejercicio", Terapia de ejercicio "y" Anciano "se utilizaron entre 2015 y 2020. Se buscaron artículos en español, inglés y portugués realizados en personas de 65 años o más. Se incluyeron 101 de 4.642 ensayos aleatorizados controlados (ECA), en una muestra total de 5.013 adultos mayores (79% mujeres), con una edad promedio de 68,2 años, que iniciaron sus estudios finalizando 4.312, presentando una adherencia a las intervenciones del 86%. La mayoría de los estudios fueron realizado en adultos mayores sanos, en lugares habilitados para la práctica de actividad física, a cargo de un profesional de actividad física, y las intervenciones se realizaron a través de ejercicio terapéutico grupal. Ningún artículo reportó información sobre el tiempo mínimo de participación a la sesión Sólo el 30% de los artículos informaron la participación mínima de los adultos mayores en la intervención para incluirlos en el análisis del estudio, y el 21% informó el número medio de sesiones. atendidos a la intervención. Los principales motivos de abandono fueron causas personales ajenas a la intervención. Solo el 5% de los artículos reportaron lesión de uno de los participantes (en dos de ellos la lesión estuvo relacionada con la intervención aplicada). Esta revisión caracterizó los programas de ejercicio físico en adultos mayores en América Latina, así como las características de adherencia y los principales motivos de abandono a las intervenciones basadas en ejercicio físico, al resumir la evidencia disponible derivada de ECA.

Los altos índices de obesidad y el aumento del tiempo sedentario en los escolares tienen consecuencias directas en la prevalencia de enfermedades no transmisibles en edad adulta. El entorno escolar es una oportunidad para combatir estos factores de riesgo y la importancia de la clase de educación física es relevante. El objetivo del estudio fue comparar el nivel de actividad física, gasto energético y tiempo sedentario entre una jornada con y sin clases de educación física en niños y niñas de primer ciclo básico. Es un estudio no experimental, analítico transversal con una muestra intencionada de 46 escolares de primer ciclo básico. Se midió índice de masa corporal (IMC), actividad física, gasto energético y tiempo sedentario con acelerometría en jornada escolar con y sin clase de educación física. Se utilizó la prueba no paramétrica de Wilcoxon para determinar diferencias entre las jornadas escolares (p < .05). Los resultados muestran que, durante la jornada con clases de educación física, los escolares presentaron un nivel de actividad física moderada (3.03 MET) y, en la jornada sin clases de educación física, un nivel ligero (2.32 MET). Los estudiantes en la jornada escolar con educación física tuvieron mayores niveles de actividad física moderada (Z = -4.430; p < .0001), vigorosa (Z = -5.403; p < .0001), muy vigorosa (Z = -3.940; p < .0001) y disminuyeron el tiempo sedentario (Z = -4.149; p < .0001) con respecto a la jornada sin clase de educación física. Se concluye que aun cuando durante la jornada con educación física, los escolares tienen mayor actividad física, mayor gasto energético y menor tiempo sedentario, este rendimiento resulta insuficiente de acuerdo con las recomendaciones internacionales para la salud.

School coexistence is a fundamental aspect for good academic performance. The objective of the study was to identify school coexistence indices, and to analyze differences in academic performance according to these indices in students from public schools in the province of Biobío, Chile. This cross-sectional study involved 730 children (53.8% boys; 12 ± 1.2 years). School coexistence indices as a quality of interpersonal relationships between school bodies, the perception of violence and aggressiveness from a gender perspective, and the perception of levels of safety and unsafety in different school areas as well as academic performance through accumulated final grades (AFG) and grade point averages (GPA) were measured. A total of 40.9% and 41.3% of schoolchildren agreed or strongly agreed that stronger students are violent toward weaker students and boys are violent toward one another, respectively. The school areas most classified as unsafe or very unsafe were the restrooms (20.4%), followed by the playgrounds (10%), and the gym and fields (9.5%). Schoolchildren who classified the relationships within the school bodies as bad, or very bad, presented significantly lower AFG in subjects such as math, language (Spanish), and physical education and health as well as GPA. In the same line, those who perceived greater violence and aggressiveness among peers and higher insecurity in different school areas presented significantly poorer academic performance. In conclusion, students perceived violence and aggressiveness among themselves, and the school areas perceived as unsafe were identified. Furthermore, students who perceived poorer school coexistence indices presented a weaker academic performance.

In the past few years, the level of physical fitness in children has decreased globally. According to the SIMCE test carried out in 2015, 45% of 8th year students in Chile were overweight. Moreover, international studies have shown that being overweight is associated with the development of chronic illnesses, negatively affecting cognitive mechanisms and processes. Nevertheless, there is little to no evidence that analyzes the relationship between physical fitness and executive functions in students, at a national level. The aim was to analyze the relationship between cardiorespiratory, musculoskeletal, and motor fitness, and performance in an executive functions test, in students from a public school in the south of Chile. A qualitative, descriptive –correlational, non-experimental, and cross-sectional approach was used. In total, 100 students between 9 and 12 and 11 months of age from a public school in the south of Chile completed the physical fitness assessments through the ALPHA fitness test, and 81 students completed the executive function assessments through the ENFEN test. It was evidenced that students who achieved a longer duration of time and a later stage in the Course Navette test, more centimeters in the standing broad jump (SBJ) test, and a shorter duration in the 4 × 10 shuttle run obtained a better score in the gray trail test. Additionally, students who presented a stronger dominant handgrip scored higher in the colored trail tests. We conclude that students who show a higher level of physical fitness also present a better development of executive functions such as working memory and inhibitory control. In addition, these results suggest physical condition is a factor to consider for better cognitive and school performance.

Studies that analyze the predictors of satisfaction with the health of the elderly are scarce. That is the reason why the objective of this study is to analyze whether the physical-psychological state, sports practice, and the use of socio-health resources are factors that predict satisfaction with health status in physically active elderly people. The Physical Activity and Quality of Life questionnaires were applied to a sample of 397 elderly people in this cross-sectional observational study. The data have been analyzed using Student’s t-test chi-square test, Cohen’s d, Phi Coefficient and Cramer’s V. The results have shown that the lack of physical illnesses (OR = 3.920; p < 0.001) and psychological problems (OR = 1.940; p = 0.032), practicing a high level of physical activity (OR = 2.049; p = 0.001), having high scores in functional skills (OR = 8.059; p < 0.001) and using little social and health services (OR = 2.595; p < 0.001) are all predictors of being highly satisfied with one’s health. In conclusion, predictors associated with high health satisfaction of active older people have been found, such as functional abilities, the existence of physical illness, psychological problems, level of physical activity, frequency of use of health and social services and satisfaction with health and social services; but it is not associated with gender or age of participants.

Introdution: The environment and the type of co-living of older people are crucial to understanding how the nature of their context influences a healthy lifestyle. However, no studies have investigated to what extent their type of co-living may be associated with the sports and the profile practice according to their age. Objective: This study aimed to assess the association between the types of co-living and the age of the physically active elderly and the sports they practice. Hypothesis: It is thought that the age, situation, and satisfaction with the way of living in physically active older people differ according to the type of sport they practice. Methods: Cross-sectional study. We included 358 individuals aged between 61 and 93 years old (M = 69.66, SD = 4.74). Type of co-living was classified as living alone or living with others. The sports activities evaluated were: gym, dance, water activities, and yoga/pilates. Differences in the type of co-living and sports practiced were evaluated by ANOVA or Chi2. Results: Among the elderly who practice gymnastics, most of them live alone and in a tight core (p < 0.001) (Phi = 0.244). Furthermore, those who practice aquatic activities are more frequently the youngest (p < 0.001) (Phi = 0.198). Conclusion: Older people who do gymnastics have smaller living groups, those under 69 opt for gymnastics and aquatic activities, while those aged 70 and over prefer dance, yoga, and pilates.

Objective: To analyze the effects of movement representation techniques (MRT) combined with conventional physical therapy (CFT) in people undergoing knee and hip arthroplasty compared to conventional physical therapy alone in terms of results in physical and functionality variables, cognitive function, and quality of life. Methodology: the review was carried out according to the criteria of the PRISMA statement, considering studies in the electronic databases PubMed/Medline, Pubmed Central/Medline, Web of Science, EBSCO, and ScienceDirect. Results: MRT plus CFT generated therapeutic effects in some aspects of the physical variables: 100% pain (7 of 7 studies); 100% strength (5 out of 5 studies); range of motion 87.5% (7 out of 8 studies); 100% speed (1 of 1 study), functional variables: 100% gait (7 of 7 studies); functional capacity 87.5% (7 out of 8 studies); cognitive variables: 100% motor visualization ability (2 out of 2 studies); cognitive performance 100% (2 of 2 studies); and quality of life 66.6% (2 of 3 studies). When comparing its effects with conventional physical therapy, the variables that reported the greatest statistically significant changes were motor visualization ability, speed, pain, strength and gait. The most used MRT was motor imagery (MI), and the average time extension of therapies was 3.5 weeks. Conclusions: movement representation techniques combined with conventional physical therapy are an innocuous and low-cost therapeutic intervention with therapeutic effects in patients with knee arthroplasty (KA) and hip arthroplasty (HA), and this combination generates greater therapeutic effects in physical, functional, and cognitive variables than conventional physical therapy alone.

Context: High-intensity interval training (HIIT) is considered a time-efficient strategy to improve cardiometabolic health markers in children and adolescents. However, the evidence regarding the characterization of each intervention and the quantification of their health effects within the school environment is required. Objectives: To systematically review the characteristics of HIIT-based interventions during school time and quantify their effects on the health of children and adolescents. Data Sources: Recommendation of PRISMA for systematic review was applied. The protocol was registered in the PROSPERO repository 2018 CRD42018089017. A search of the literature (2008 - 2018) on the databases PubMed,Web of Science, CINHAL and PsycINFo was carried out. Study Selection: Twelve publications using HIIT on children and adolescents in a school-based environment were selected. The inclusion criteria were: (1) HIIT; (2) intervention and, (3) type of study. Data Extraction: The inclusion criteria to the titles and abstracts, or three independent researchers analyzed the articles. PRISMA’s recommendation for systematic reviews, Cochrane tool and ROBINS for randomized and non-randomized studies were used. Results: We identified 12 studies that included a total of 917 children and adolescents; 83% of the interventions were performed during physical education classes. The average duration and intensity of the interventions were 8 weeks and > 90% HR, respectively. The most important variables evaluated and impacted by HIIT were cardiovascular fitness, nutritional status, and physiological wellbeing. Conclusions: HIIT seems to be a reliable and time-efficient approach to impact especially cardiovascular fitness of children and adolescents during school time. The focus on class intensity and the number of repetitions needs further investigation to find interventions based on each school due to individual differences regarding time and implementation constraints to impact health parameters.

Current evidence suggests that attitude towards older people may be associated with sociodemographic and educational variables; hence, a positive attitude towards older people is key when training new university professionals. However, there is little evidence of this association in Chilean university students. The objective was to analyze students from a Chilean university’s attitudes towards older people, according to sociodemographic and educational variables. Analytical and cross-sectional study; 515 students from a Chilean university were consulted online about their attitude towards older people using Kogan’s Attitudes towards Old People scale. Additionally, sociodemographic and educational variables were recorded. The average score for positive attitude was 70.8 (±9.7), while the negative attitude score was 68.3 (±11.6). The total score was 139.1 (±16.6). Mostly, university students perceive themselves with a low-level positive attitude (61.2%). Additionally, older university students (26–42 years old); women; Chileans; students of law, speech therapy, and occupational therapy; students in their final years of the programs; and those who had training in older people outside the university have a more positive attitude towards older people. In Conclusion, a profile of sociodemographic and educational characteristics of students with a lower and higher attitude towards older age was investigated. These results are relevant since the way of seeing the aging process could regulate the training of future professionals and consequently generate changes in dealing with older people. Young people’s perception of ageing would affect the treatment and incorporation of the older people in society and the adaptation of policies in this age group.

There has not been much study of risk profiles in older people according to different levels of practice in physical activity. For this reason, the aim of this research was to evaluate whether the elements that influence the quality of life and factors such as gender and education can predict the level of physical activity in the physically active elderly population. The Fernández–Ballesteros quality of life questionnaire and the WHO International Physical Activity Questionnaire were applied to a sample of 397 people with a mean age of 69.65 years (SD = 4.71). The results revealed the following predictive factors of practicing a low level of physical activity (p < 0.05): being a woman; having a low educational level; and low scores in activity and leisure and in functional skills. In conclusion, gender, education, functional skills, activity and leisure, and health are elements of quality of life that predict the level of physical activity performed by the elderly, where it is necessary to use leisure activities (visiting friends, playing games, running errands) as an indirect way to increase participation in physical activity.

Understanding the perception that students have about their own cognitive processes is a key aspect that allows for a deeper assimilation of the different factors that affect school performance. However, there is limited evidence explaining the link between students’ perception of their own cognitive functions and their academic performance. The objective of this study was to analyze the association between perception of cognitive functions, such as memory, processing speed, attention, execution of complex tasks and nervousness, and academic performance in Chilean schoolchildren from the province of Biobio. A cross-sectional analytic design was conducted. The sample consisted of 590 elementary school students (12 ± 1.3 years old; 48.3% female) from Chilean public schools. The academic performance was measured by means of the accumulated final grades in the language, mathematics, physical education and health subjects, and the grade point average (GPA) of each student. Moreover, a survey to measure the cognitive functions of the participants was applied. The results show that 20.3% of the students perceived themselves as very nervous and 16.8% felt distracted. Differences in marks were observed in all the measured subjects, as well as in GPAs, depending on the perception of cognitive functions. Thus, the students with low to moderate perceptions of their cognitive functions received lower marks than those who reported a high perception. These results were consistent after a multivariate analysis adjusted for a socio-educational variables model. In conclusion, one in five public school students in the Biobío Region of Chile expressed a low perception of their cognitive functions, which is consistent with their weaker school performance. Therefore, it is believed that integrating curricular activity and cognitive work could potentially boost the perception of said functions, and thus reduce the risk of poor academic performance.

Introducción: Durante el envejecimiento se observa involución de algunos sistemas corporales. Entre estos cambios, los que afectan al sistema osteomuscular como la sarcopenia y la debilidad muscular, pueden alterar el desarrollo de actividades de la vida diaria, y por lo tanto, afectar la calidad de vida relacionada con la salud. Objetivo: Determinar la relación entre la fuerza de prensión manual y la calidad de vida relacionada con la salud en personas mayores. Métodos: Estudio descriptivo, correlacional. Evaluó 79 personas mayores (63 mujeres y 16 hombres) entre 65 y 78 años, de tres organizaciones sociales de la ciudad de Talca, Chile, seleccionados a través de un muestreo no probabilístico por conveniencia. Para medir la fuerza de prensión manual se utilizó un dinamómetro de mano y el cuestionario SF-36 fue usado para valorar la calidad de vida relacionada con la salud. Resultados: Se observaron relaciones significativas entre la fuerza de prensión manual y las dimensiones de la calidad de vida función física (p = 0,03; r = 0,76), dolor corporal (p = 0,01; r = 0,44) y salud general (p = 0,05; r = 0,48). Conclusiones: Existe relación entre la fuerza de prensión manual y tres dimensiones de la calidad de vida relacionada con la salud de personas mayores. Estos hallazgos corroboran la relevancia de evaluar la fuerza muscular en personas mayores como un marcador de salud y calidad de vida en estas.

Introduction: During aging, involution of some body systems is observed. Among these changes, those that affect the musculoskeletal system such as sarcopenia and muscle weakness can alter the development of activities of daily life, and therefore affect health-related quality of life. Objective: to determine the relationship between hand grip strength and quality of life in elderly. Methods: Cross-sectional study. A total of 79 elderly (63 women and 13 men) between 65 and 78 years of age from three social organizations of Talca, Chile was included. A non-probabilistic convenience sample was used. To measure manual grip strength and the SF-36 questionnaire was used. Results: Significant relationships between hand grip strength and dimensions of quality of life, physical function (p=0,03; r=0.76), body pain (p=0,01; r=0,44) and general health (p=0,05; r=0,48) were observed. Conclusions: There is a relationship between hand grip strength and three measurements of quality of life in elderly. These findings corroborate the relevance of evaluating muscle strength in older people as a marker of health and quality of life in elderly.

The factors that make physically active older people feel more satisfied in adulthood have not been extensively studied. For this reason, the aim of this work has been to evaluate, among physically active older adults, whether the level of physical activity they perform and the factors that foster their quality of life can be predictors of their satisfaction with life. For this, the IPAQ, CUBRECAVI and LSI-A scales were applied to a sample of 397 people between 61 and 93 years old (M = 69.65, SD = 4.71). The results show that health (β = 0.373), functional abilities (β = 0.159) and environmental quality (β = 0.105) are predictors of satisfaction in the most active adults. In conclusion, neither physical activity (to a greater or lesser extent) nor income are predictive variables of satisfaction with life but, rather, predict some of the components that cement their quality of life (health, fending for themselves and the home environment).

Objective: To compare cardiovascular risk and cardiorespiratory capacity in schoolchildren from a region in the extreme south of Chile according to nutritional status and muscular strength. Methods: An analytical cross-sectional study was performed on a sample of 594 schoolchildren from 5th to 8th grade in the extreme south of Chile. Based on body mass index and lower limb muscle strength, participants were divided into four groups: high strength-normal weight, high strength-overweight/obese, low strength-normal weight, and low strength-overweight/obese. Then, waist-to-height ratio and cardiorespiratory capacity, measured with the 20 m shuttle run test, were assessed to determine their cardiovascular risk, comparing the four groups. Results: The overweight/obese group with high muscular strength presented better indicators in anthropometric variables (waist circumference and waist-to-height ratio) than their peers with low muscular strength. Additionally, the overweight/obese group with low muscular strength presented a lower cardiorespiratory capacity than their peers with high muscular strength. Both results were observed in boys and girls. Conclusion: The results of this study suggest that overweight/obese schoolchildren with high muscle strength present healthier anthropometric indicators and greater cardiorespiratory capacity than their peers with low muscle strength. These results confirm the relevance of measuring muscle strength in schoolchildren and its usefulness to assess functionality. These results encourage the scientific community to continue studying the role that muscle strength plays in modulating the effects of overweight and obesity on respiratory and cardiovascular conditions in childhood.

Introduction: Volume and intensity are major variables governing exercise training-mediated beneficial effects in both athletes and patients. Although polarized endurance training optimizes and maximizes physiological gains in highly trained individuals, its cardiometabolic protective-effects have not been established. The purpose of the present single site, randomized-controlled trial was to compare the effects of 12-weeks of high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), and polarized volume training (POL) programs on cardiometabolic risk factors in young overweight and obese women.Materials and Methods: A total of 64 overweight/obese young women (age 23.3 ± 3.8 years, body mass index 33.8 ± 3.8 kg/m2) were randomly assigned to four groups: control group (CTRL), polarized volume training group, moderate-intensity endurance training group, and HIIT group. The cardiorespiratory capacity, glycemic and lipid profiles, whole-body substrate utilization, and body composition were assessed before and after the intervention.Results: After the intervention, VO2peak and power output at VO2peak increased in all exercised-groups (time effect: p < 0.0001). Power output at VT1 was increased only in the POL group compared to the CTRL group (p = 0.019). Relative fold changes in fasting plasma glucose concentrations decreased only in POL group (p = 0.002). Training induced a significant increase in relative fat oxidation in all the groups (time effect: p < 0.001). Relative fat oxidation increased only in the POL group compared to the CTRL group (training effect: p = 0.032).Conclusion: Twelve-weeks of polarized volume training showed overall superior effects on cardiorespiratory fitness, basal glycemic control, and substrate oxidation in comparison to MICT and HIIT training modalities. These data suggest that polarized volume training is an effective non-pharmacological treatment strategy for reducing cardiovascular disease risk factors in young overweight and obese women. The trial is registered at ISRCTN, number ISRCTN34421723.

The current prevalence of diet-induced overweight and obesity in adolescents and adults is continuously growing. Although the detrimental biochemical and metabolic consequences of obesity are widely studied, its impact on stress-coping behavior and its interaction with specific exercise doses (in terms of intensity, duration and frequency) need further investigation. To this aim, we fed adolescent rats either an obesogenic diet (cafeteria diet, CAF) or standard chow (ST). Each group was subdivided into four subgroups according to the type of treadmill intervention as follows: a sedentary group receiving no manipulation; a control group exposed to a stationary treadmill; a low-intensity treadmill group trained at 12 m/min; and a higher intensity treadmill group trained at 17 m/min. Both the diet and treadmill interventions started at weaning and lasted for 8 weeks. Subjects were tested for anxiety-like behavior in the open field test and for coping strategies in the two-way active avoidance paradigm at week 7 and were sacrificed at week 8 for biometric and metabolic characterization. CAF feeding increased the weight gain, relative retroperitoneal white adipose tissue (RWAT %), and plasma levels of glucose, insulin, triglycerides and leptin and decreased the insulin sensitivity. Treadmill intervention partially reversed the RWAT% and triglyceride alterations; at higher intensity, it decreased the leptin levels of CAF-fed animals. CAF feeding decreased the motor activity and impaired the performance in a two-way active avoidance assessment. Treadmill intervention reduced defecation in the shuttle box, suggesting diminished anxiety. CAF feeding combined with treadmill training at 17 m/min increased the time spent in the center of the open field and more importantly, partially reversed the two-way active avoidance deficit. In conclusion, this study demonstrates that at doses that decreased anxiety-like behavior, treadmill exercise partially improved the coping strategy in terms of active avoidance behavior in the CAF-fed animals. This effect was not observed at lower doses of treadmill training.

Among adolescents, overweight, obesity and metabolic syndrome are rapidly increasing in recent years as a consequence of unhealthy palatable diets. Animal models of diet-induced obesity have been developed, but little is known about the behavioural patterns produced by the consumption of such diets. The aim of the present study was to determine the behavioural and biochemical effects of a cafeteria diet fed to juvenile male and female rats, as well as to evaluate the possible recovery from these effects by administering standard feeding during the last week of the study. Two groups of male and female rats were fed with either a standard chow diet (ST) or a cafeteria (CAF) diet from weaning and for 8 weeks. A third group of males (CAF withdrawal) was fed with the CAF diet for 7 weeks and the ST in the 8th week. Both males and females developed metabolic syndrome as a consequence of the CAF feeding, showing overweight, higher adiposity and liver weight, increased plasma levels of glucose, insulin and triglycerides, as well as insulin resistance, in comparison with their respective controls. The CAF diet reduced motor activity in all behavioural tests, enhanced exploration, reduced anxiety-like behaviour and increased social interaction; this last effect was more pronounced in females than in males. When compared to animals only fed with a CAF diet, CAF withdrawal increased anxiety in the open field, slightly decreased body weight, and completely recovered the liver weight, insulin sensitivity and the standard levels of glucose, insulin and triglycerides in plasma. In conclusion, a CAF diet fed to young animals for 8 weeks induced obesity and metabolic syndrome, and produced robust behavioural changes in young adult rats, whereas CAF withdrawal in the last week modestly increased anxiety, reversed the metabolic alterations and partially reduced overweight.
