This is an overview of the results from 14 countries or jurisdictions in a Global Matrix of Para Report Cards on physical activity (PA) of children and adolescents with disabilities. The methodology was based on the Active Healthy Kids Global Alliance’s Global Matrix 4.0. Data were aligned with 10 indicators (Overall PA, Organized Sport, Active Play, Active Transport, Physical Fitness, Sedentary Behavior, Family & Peers, Schools, Community & Environment, and Government) to produce Para Report Cards. Subsequently, there were 139 grades; 45% were incomplete, particularly for Active Play, Physical Fitness, and Family & Peers. Collectively, Overall PA was graded the lowest (F), with Schools and Government the highest (C). Disability-specific surveillance and research gaps in PA were apparent in 14 countries or jurisdictions around the world. More coverage of PA data in Para Report Cards is needed to serve as an advocacy tool to promote PA among children and adolescents with disabilities.

Background: To estimate the prevalence of different physical activity (PA) domains and sitting time (ST), and to analyze the association with sociodemographic indicators. Methods: Data from the most recent nationally representative survey from each of the South American countries, comprising 155,790 adults (18–64 y), were used. Data on leisure-time, transport, and occupational PA (all 3 domains as nonzero), total PA (≥150 min/wk), and ST (≥8 h/d) were assessed by specific questionnaires in each survey. Gender, age group (18–34, 35–49, and 50–64 y), and education (quintiles) were used as sociodemographic factors. Random effect meta-analysis of the association between sociodemographic factors and PA and ST were conducted. Results: The prevalence of PA guidelines compliance and elevated ST in South America was 70.3% and 14.1%, respectively. Women were less likely to achieve the recommended levels of total and domain-based PA. Participants in the highest quintile of education were more likely for elevated ST (2.80, 2.08–3.77), lower occupational PA (0.65, 0.44–0.95), but higher leisure-time PA (3.13, 2.31–4.27), in comparison with lowest quintile. Older adults were less likely to participate in total and leisure-time PA. Conclusion: Our findings highlight the urge to tackle the inequalities in PA practice in South America, especially gender and education inequalities, for leisure-time PA.

Background: The Global Matrix 4.0 on physical activity (PA) for children and adolescents was developed to achieve a comprehensive understanding of the global variation in children’s and adolescents’ (5–17 y) PA, related measures, and key sources of influence. The objectives of this article were (1) to summarize the findings from the Global Matrix 4.0 Report Cards, (2) to compare indicators across countries, and (3) to explore trends related to the Human Development Index and geo-cultural regions. Methods: A total of 57 Report Card teams followed a harmonized process to grade the 10 common PA indicators. An online survey was conducted to collect Report Card Leaders’ top 3 priorities for each PA indicator and their opinions on how the COVID-19 pandemic impacted child and adolescent PA indicators in their country. Results: Overall Physical Activity was the indicator with the lowest global average grade (D), while School and Community and Environment were the indicators with the highest global average grade (C+). An overview of the global situation in terms of surveillance and prevalence is provided for all 10 common PA indicators, followed by priorities and examples to support the development of strategies and policies internationally. Conclusions: The Global Matrix 4.0 represents the largest compilation of children’s and adolescents’ PA indicators to date. While variation in data sources informing the grades across countries was observed, this initiative highlighted low PA levels in children and adolescents globally. Measures to contain the COVID-19 pandemic, local/international conflicts, climate change, and economic change threaten to worsen this situation.

Background: The purpose was to determine the proportion of 9- to 11-year-old children meeting the 24-hour movement guidelines (24-HMG) in a low-income town from Chile. Methods: Physical activity, sedentary behavior (recreational screen), and sleep times were measured with both questionnaire and accelerometer in 258 children from third to sixth grade. Meeting the 24-HMG was defined as having ≥60 minutes per day of moderate to vigorous physical activity, ≤2 hour day of screen time, and 9 to 11 hours of sleep per night. Compliance rates were calculated as self-reported 24-HMG, with all estimations based on questionnaires, and mixed 24-HMG, in which physical activity and sleep were determined with an accelerometer and sedentary behavior was determined with a questionnaire. Results: About 198 children (10.1 [0.8] y, range 9–11 y) provided valid data for estimating self-reported 24-HMG, and 141 for mixed 24-HMG. Only 3.2% and 0.7% met the 24-HMG when using the self-reported and mixed methods, respectively. When assessing individual recommendations, 13.1% and 3.7% of the sample were physically active based on the self-report and accelerometer, respectively. About a quarter met the sedentary behavior recommendations, while around 50% met the sleep recommendations with both self-reported and mixed methods. Conclusions: An extremely low percentage of the participants met the 24-HMG. Multicomponent initiatives must be implemented to promote healthy movement behaviors in Chilean children.

Department of Physical Education; Brasil Abstract: Background We aimed to investigate time trends and inequalities of different physical activity (PA) domains and sitting time (ST) in adults from South American countries. Methods We included cross-sectional data of nationally representative surveys on adults (n=597843) from nine South American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Uruguay, and Venezuela), with data collection time frames ranging from 2005 to 2020. Data on different PA domains (leisure-time, transport, and occupational) and ST were assessed through questionnaires. Trends according to education level (quintiles), gender (m/w), and age group (18-34 years, 35-49 years, 50-64 years) were estimated for the harmonized indicators of nonzero PA in the different domains, ≥150min/week of total PA and ≥8hours/d of ST. Results Chile (2009/2010=78.9% vs 2016/2017=70.5%), and Peru (2009/2010=78.6% vs 2011=69.6%) reduced total PA, while Brazil (2013=57.3% vs 2019=67.0%) and Uruguay (2006=69.4% vs 2013=79.4%) increased, and Argentina and Venezuela maintained. There was an increasing trend for ST in Argentina, Peru, and Uruguay. Leisure-time PA increased in most countries (6/8 countries). Transport PA was relatively stable, while occupational PA presented mixed findings. Education inequalities increased over time for total and leisure-time PA, while age and gender inequalities were relatively constant. Conclusions Future South American countries’ efforts may be warranted to promote PA and reduce ST in adults, while addressing inequalities when implementing actions.

Review question / Objective: This systematic review aims to provide evidence of attributes for the concept and structure of the term physical literacy for its understanding in Spanish-speaking countries mainly from Latin America and Spain. Condition being studied: Many definitions of physical literacy refer to a lifelong participation in physical activity, presenting multiple benefits for people's health. Therefore, many organizations (universities, government entities, research groups) in different countries promote interventions for its development. However, the approach to these interventions is based on different concepts and attributes, depending on the country where they are organized. Taking into account that physical literacy is a global approach that is being disseminated worldwide, it is necessary to analyze its different conceptualizations, carrying out a systematic review that presents evidence of how physical literacy is being understood around the world. By describing the attributes characterizing the concept and structure of physical literacy, we aim to contextualize and enhance the understanding of physical literacy in Spanish-speaking countries and regions from Spain, Latin America, Africa and Asia which involve more than 500 millions of people.

Introduction 24-hour movement behaviours (physical activity, sedentary behaviour and sleep) during the early years are associated with health and developmental outcomes, prompting the WHO to develop Global guidelines for physical activity, sedentary behaviour and sleep for children under 5 years of age. Prevalence data on 24-hour movement behaviours is lacking, particularly in low-income and middle-income countries (LMICs). This paper describes the development of the SUNRISE International Study of Movement Behaviours in the Early Years protocol, designed to address this gap. Methods and analysis SUNRISE is the first international cross-sectional study that aims to determine the proportion of 3- and 4-year-old children who meet the WHO Global guidelines. The study will assess if proportions differ by gender, urban/rural location and/or socioeconomic status. Executive function, motor skills and adiposity will be assessed and potential correlates of 24-hour movement behaviours examined. Pilot research from 24 countries (14 LMICs) informed the study design and protocol. Data are collected locally by research staff from partnering institutions who are trained throughout the research process. Piloting of all measures to determine protocol acceptability and feasibility was interrupted by COVID-19 but is nearing completion. At the time of publication 41 countries are participating in the SUNRISE study. Ethics and dissemination The SUNRISE protocol has received ethics approved from the University of Wollongong, Australia, and in each country by the applicable ethics committees. Approval is also sought from any relevant government departments or organisations. The results will inform global efforts to prevent childhood obesity and ensure young children reach their health and developmental potential. Findings on the correlates of movement behaviours can guide future interventions to improve the movement behaviours in culturally specific ways. Study findings will be disseminated via publications, conference presentations and may contribute to the development of local guidelines and public health interventions.

La obesidad infantil es un problema grave en Latinoamérica y entre la población latina de EE. UU. Para ser eficaces, las políticas de salud pública tienen que estar guiadas por evidencias contextuales pertinentes, lo cual exige una capacidad de investigación sostenida a través del tiempo. Los objetivos de este estudio son determinar la productividad de la investigación enfocada en las poblaciones latinas en Latinoamérica y Estados Unidos, y examinar los dominios de la capacidad de investigación (infraestructuras, programas de formación, mentoría, financiamiento y redes de contactos). Realizamos una revisión exploratoria de artículos indexados relacionados con la obesidad infantil publicados entre junio de 2015 y diciembre de 2019. Recabamos información sobre las percepciones de los investigadores latinoamericanos respecto a la capacidad de investigación en obesidad infantil a través de una encuesta en línea. Identificamos 612 artículos relacionados con la obesidad infantil (505 de Latinoamérica, 124 de EE. UU. y 17 de colaboraciones entre EE. UU. y Latinoamérica). Brasil, México, Chile, Colombia y Estados Unidos son los países con más publicaciones. Encontramos aproximadamente el mismo número de artículos sobre obesidad, nutrición y actividad física; sin embargo, observamos que la capacidad de investigación sobre actividad física está rezagada en otros dominios (formación en investigación, financiamiento y oportunidades para establecer contactos). Otras áreas de investigación complementarias, como el comportamiento sedentario, la ciencia de sistemas y los estudios de políticas, son poco frecuentes en Latinoamérica, pero más habituales en Estados Unidos, mientras que la investigación sobre el sueño es incipiente en ambas regiones. Para cumplir la promesa de crear un programa eficaz de colaboración transfronteriza para la prevención de la obesidad infantil será necesario invertir en todos los dominios de la capacidad de investigación y en todos los temas pertinentes.

Carlos Cristi-Montero received funding for the Cogni-Action Project from the National Commission for Scientific and Technological Research CONICYT/FONDECYT INICIACION 2016 grant No. 11160703 (Chile), and the National Research and Development Agency (ANID) from Chile-2019, Postdoctoral Grant No. 74200071., The first aim was to compare differences between school vulnerability groups, fitness levels, and their combination in adolescent cognitive performance. The second aim was to determine the mediation role of fitness in the association between school vulnerability and cognitive performance. A total of 912 Chilean adolescents aged 10–14 years participated in this study. The school vulnerability index (SVI) assigned by the Chilean Government was categorized into high-, mid-, or low-SVI. Adolescents were classified as fit or unfit according to their global fitness z-score computed from their cardiorespiratory (CRF), muscular (MF), and speed/agility fitness (SAF) adjusted for age and sex. A global cognitive scorewas estimated through eight tasks based on a neurocognitive battery. Covariance and mediation analyses were performed, adjusted for sex, schools, body mass index, and peak high velocity. Independent analyses showed that the higher SVI, the lower the cognitive performance (F(6,905) = 18.5; p < 0.001). Conversely, fit adolescents presented a higher cognitive performance than their unfit peers (F(5,906) = 8.93; p < 0.001). The combined analysis found cognitive differences between fit and unfit adolescents in both the high- and mid-SVI levels (Cohen’s d = 0.32). No differences were found between fit participants belonging to higher SVI groups and unfit participants belonging to lower SVI groups. Mediation percentages of 9.0%, 5.6%, 7.1%, and 2.8% were observed for the global fitness score, CRF, MF, and SAF, respectively. The mediation effect was significant between lowwith mid-high-SVI levels but not between mid- and high-SVI levels. These findings suggest that an adequate physical fitness level should be deemed a protective social factor associated with bridging the cognitive gap linked to school vulnerability in adolescents. This favourable influence seems to be most significant in adolescents belonging to a more adverse social background., National Commission for Scientific and Technological Research CONICYT/FONDECYT INICIACION (Chile) 11160703, National Research and Development Agency (ANID) from Chile 74200071

Background: Little is known about of correlates of physical activity (PA), sedentary behaviour (SB), and sleeping in children from Latin America. The aim of this study was to assess the association between potential correlates with device-measured PA, SB and sleeping time in children from 9 to 11 years in Carahue, Chile. Methods: A cross-sectional study was conducted to assess correlates of physical behaviours (demographic, psychological, behavioural, home and school environment factors) from data reported by participants and caregivers. Each participant wore an ActiGraph GT3X+ accelerometer on the hip during seven consecutive days to measure PA, SB and sleeping time. Results: In total, 148 participants completed the study (47.3% male, 10.0±0.8 years). SB was positively associated with age, being female, family income, total screen time and distance to places, and negatively with higher scores of parent support for PA. Light PA was associated with age, family income, total screen time (all negative), and parent support for PA (positive). Moderate PA was associated with being male, self-efficacy and established healthy lifestyle committee at school. Vigorous PA was associated with being male, self-efficacy (both positive) and BMI z-score (negatively). Sleeping time was associated with age, portable videogame ownership (both negative) and PE minutes/week (positive).Conclusion: Variables from different levels explained each behaviour, reinforcing the need for multilevel strategies for promoting and helping to ensure healthier lifestyles in children.Resumen. Antecedentes: se sabe poco sobre los correlatos de la actividad física (PA), el comportamiento sedentario (SB) y el sueño en niños de América Latina. El objetivo de este estudio fue evaluar la asociación entre los posibles correlatos con la PA, la SB y el tiempo de sueño medidos por el dispositivo en niños de 9 a 11 años en Carahue, Chile. Métodos: se realizó un estudio transversal para evaluar los correlatos de los comportamientos físicos (factores demográficos, psicológicos, de comportamiento, del entorno escolar y del hogar) a partir de los datos informados por los participantes y los cuidadores. Cada participante usó un acelerómetro ActiGraph GT3X + en la cadera durante siete días consecutivos para medir la PA, SB y el tiempo de sueño. Resultados: En total, 148 participantes completaron el estudio (47.3% hombres, 10.0 ± 0.8 años). SB se asoció positivamente con la edad, el hecho de ser mujer, el ingreso familiar, el tiempo total de la pantalla y la distancia a los lugares, y negativamente con puntuaciones más altas de apoyo de los padres para PA. La PA leve se asoció con la edad, el ingreso familiar, el tiempo total de la pantalla (todo negativo) y el apoyo de los padres para la PA (positivo). La PA moderada se asoció con ser hombre, autoeficacia y un comité de estilo de vida saludable establecido en la escuela. La PA vigorosa se asoció con ser hombre, autoeficacia (ambos positivos) y puntaje BMI (negativo). El tiempo de sueño se asoció con la edad, la propiedad de los videojuegos portátiles (ambos negativos) y los minutos / semana de PE (positivo) .Conclusión: las variables de diferentes niveles explicaron cada comportamiento, lo que refuerza la necesidad de estrategias multinivel para promover y ayudar a garantizar estilos de vida más saludables en los niños.

Objectives The purpose of this study was to determine the number of monitoring days needed to reliably measure weekly activity behaviours with the ActivPAL (AP) monitor in adults. Design Cross-sectional study. Methods Participants (90 adults (51.1% men); age = 39.1 ± 12.43 years) wore an AP for 7 consecutive days. Mean time spent sitting/lying, standing and stepping per day, and mean number of transitions from sitting to standing per day were calculated for each participant using 7 days of monitoring (reference). Estimates for these activities were also derived from a combination of randomly selected days (from 1 to 6 days), and randomly selected weekdays and weekend days, and compared with the reference using ANOVA, correlation coefficients and Bland-Altman methods Spearman–Brown Prophecy Formula, based on Intraclass correlation of 0.8, was used to predict the minimum number of days needed to represent activity behaviours as measured with the AP. Results At least five days of monitoring were necessary to achieve a reliability of 0.8 for all postures and transitions. Correlation coefficients between estimates derived from any combination of 5 days and the reference were high (rho = 0.96–0.98). When using a combination of weekdays and weekend days, mean biases were comparable with those shown by any combination of days, but 95% limits of agreement were narrower. Conclusions When using the AP for a week, data from a combination of any 5 days provided reliable estimates of all activities and transitions per day, but more precise estimates were achieved if at least 1 weekend day was included.

Summary To prevent obesity among Latino youth in the United States and Latin America, it is necessary to understand the specific context and interplay of physical activity (PA) and the built environment (BE). This paper aims to advance the research agenda of BE and PA for obesity prevention in Latin America and among Latino youth in the United States by (1) identifying environmental indicators to inform the design of interventions and policy, (2) identifying interdisciplinary methodological approaches for the study of the complex association between BE and PA, and (3) presenting case studies of PA‐promoting BE programs. A group of U.S. and Latin American scientists collaboratively worked to propose innovative indicators of the BE, methodological approaches for the study of the complex association between BE and PA, and review case studies of PA‐promoting BE programs in both regions. The results identified gaps in knowledge, proposed environmental indicators (e.g., landscape, street design, mobility patterns, and crime and safety), reviewed methodological approaches (social network analysis, citizen science methods), and case studies illustrating PA‐promoting BE programs (i.e., play streets, active school transport, and school setting interventions). The obesity prevention among Latino and Latin American youth requires advanced research on BE and PA addressing context‐specific priorities and exchanging lessons learned.

Summary Childhood obesity is a major problem in Latin America and among US Latinos. Effective public health policies require contextually relevant evidence to guide them, which demands sustained research capacity. The objectives of this study are to determine research productivity in Latin America and in the United States focused on Latino populations and examine domains of research capacity (research infrastructure, training programs, mentoring, funding, and networks). We conducted a scoping review of indexed childhood obesity‐related articles published June 2015–December 2019. We collected data on perceptions of capacity for childhood obesity research among Latin American investigators through an online survey. We identified 612 childhood obesity‐related articles (505 from Latin America, 124 from the United States, and 17 US–Latin America collaborations). Brazil, Mexico, Chile, Colombia, and the United States are the top publishing countries. There are similar numbers of obesity, nutrition, and physical activity articles, but physical activity research capacity lagged in other domains (research training, funding, and networking opportunities). Complementary research areas, including sedentary behavior, systems science, and policy studies, are uncommon in Latin America but more prevalent in the United States, whereas sleep research is nascent across settings. Realizing the promise of an effective cross‐border collaborative childhood obesity prevention agenda will require committed investment in all domains of research capacity and across all relevant topics.

Prevenir la obesidad entre los jovenes latinos que viven en Estados Unidos y en paises latinoamericanos requiere reconocer la especificidad de los contextos y las interacciones entre actividad fisica (AF) y entorno construido (EC). El objetivo de este articulo es avanzar en la agenda de investigacion sobre el EC y la AF con el fin de prevenir la obesidad en Latinoamerica y entre los jovenes latinos de Estados Unidos mediante (1) la identificacion de indicadores del entorno que contribuyan en el diseno de intervenciones y politicas; (2) la identificacion de enfoques metodologicos interdisciplinarios para el estudio de la relacion compleja que se establece entre el EC y la AF y (3) la presentacion de estudios de casos sobre programas de EC que promueven la AF. Un grupo de cientificos estadounidenses y latinoamericanos trabajo en colaboracion para proponer nuevos indicadores sobre el EC, establecer enfoques metodologicos que permitan estudiar la relacion compleja entre EC y AF, y revisar estudios de caso sobre programas de EC que promueven la AF en ambas regiones. Como resultado, se identificaron lagunas de conocimiento, se propusieron indicadores del entorno (como el paisaje, el diseno de las calles, los patrones de movilidad, la delincuencia y la seguridad), se revisaron enfoques metodologicos (analisis de redes sociales, metodos de ciencia ciudadana) y se analizaron estudios de caso de programas del EC que promueven la AF (calles para el juego, desplazamiento activo a la escuela e intervenciones en el entorno escolar). La prevencion de la obesidad entre los jovenes latinos y latinoamericanos exige una investigacion avanzada del EC y de la AF que aborde las prioridades especificas de cada contexto y permita intercambiar las lecciones aprendidas.

Background To better understand sedentary behaviour and favour international comparisons, more evidence from different countries are needed. However, there are a few tools available in Spanish to measure sedentary behaviour. This study aimed to culturally adapt, translate and validate the Past-day Adults’ Sedentary Time (PAST) questionnaire in Chilean adults compared with the ActivPAL. Method One hundred one workers wore an ActivPAL for 1 week and were asked to respond to the Spanish version of the PAST twice on different visits at a 7-day interval. The PAST assesses sedentary behaviour in several domains, including working time, during the previous day. Reliability was assessed with the intraclass correlation coefficient (ICC). Correlations and Bland-Altman methods were used to determine accuracy properties of the PAST compared with the ActivPAL. Results Seventy-seven participants provided valid data (51.0% male; age = 39.0 ± 12.39 years). The PAST showed moderate reliability (ICC = 0.63). For the total time in sedentary behavior per day, the PAST showed no correlation (r = 0.21, p = 0.07) and a mean bias of 54.9 min/day (LoA 95%: − 484.3, 594.2 min/day) with the ActivPAL. For the total time in SB at work, the PAST showed moderate reliability (ICC = 0.40), weak correlation (r = 0.37, p Conclusions The PAST performed better when estimating sedentary behaviour during working hours compared with the whole day. In this setting, accuracy properties were comparable with other self-report tools.

Movement behaviors (physical activity, sedentary behavior (including screen time), and sleep) have been impacted by the COVID-19 pandemic. We aimed to report changes in and factors influencing movement behaviors during COVID-19 among Latin American/Latino children aged 1 to 5 years in Chile, Mexico, and the USA. We conducted a cross-sectional study between April and August 2020. Caregivers reported changes in movement behaviors and provided information about family and household characteristics. In total, 4,136 children (mean age [SD], 3.1 [1.4] years; 51% boys). The proportion of children who met the WHO Guidelines decreased significantly in all countries, with large declines in meeting the physical activity and screen time guidelines. Factors associated with changes were being an older child, unable to attend an early childhood education and care service, higher parental education levels, not having the opportunity to play with someone, and not having access to spaces to play. During COVID-19, Latino parents reported changes in physical activity, screen time, and sleep quality among their toddlers and preschoolers. The findings highlight the need to minimize disparities faced by families by providing access to early childhood education and care and safe places for children to play.

Objetivo: Analizar las tendencias de búsqueda en Google en Chile sobre opciones para mantenerse activos físicamente durante etapas iniciales de la pandemia por COVID-19, y reportar la recepción de orientaciones sobre conductas físicas en cuidadores de niños y niñas de 1 a 5 años, emitidas desde salas cunas o jardines infantiles durante la pandemia en Chile. Métodos: Se exploraron términos relacionados con actividad física (“actividad física”, “ejercicio”, “juegos” y “juegos para niños en casa”) en Google teniendo como referencia el inicio de las medidas de cuarentena en Chile. La información de cuidadores se recolectó de forma online a lo largo de Chile. Resultados: De los términos explorados, “juegos para niños en casa” tuvo el mayor crecimiento desde el inicio de la pandemia, seguido por “juegos”, “ejercicio”, y “actividad física”. De un total de 1343 cuidadores, alrededor de un tercio recibió recomendaciones de actividad física, cerca de un quinto sobre uso de pantalla y uno de cada diez con relación al sueño. Conclusión: El alto interés y la falta de recepción de recomendaciones constituye un vacío que debe ser abordado a través de acciones educativas complementarias de profesionales, y tomadores de decisiones que habiliten espacios y programas para promover conductas saludables en niños y niñas en Chile.

Given the importance of physical activity and sleep for health, different recommendations have been proposed for the pediatric population. The objective of this study was to determine the association between physical activity and sleep recommendations compliance and excess weight in school children from Temuco, Chile.Physical activity and sleep were measured using ActiGraph wGT3X-BT® accelerometers. Excess weight was categorized on two categories: absence (normal weight) or presence (overweight or obesity) based on body mass index.A total of 183 school children participated (54.1 % were females; mean age = 10.95 ± 1.07). Of them, 85.4 % did not meet physical activity recommendations, whereas 75.6% did not meet sleep recommendations. Significant differences were observed in favor of boys over girls in relation to moderate and vigorous physical activity (p = 0.002), but this was not the case for amount of sleep. School children with excess weight showed less time spent in moderate and vigorous activity (p = 0.004) and a lower amount of sleep (p = 0.010) than normal weight ones. Non-compliance with physical activity recommendations was associated with excess weight (odds ratio [OR] = 8.178; 95 % confidence interval [CI]: 1.465-45.635; p = 0.017), but this was not observed in relation to sleep recommendations.A high percentage of school children do not meet the recommendations for physical activity and sleep. Associations were observed by sex and presence of excess weight. Strategies are required to promote compliance with these recommendations in the pediatric population.Introducción. Dada la importancia que la actividad física y el sueño han adquirido para la salud, se han propuesto diversas recomendaciones para la población infantil. El propósito de este estudio fue determinar cómo se asocia el cumplimiento de las recomendaciones de actividad física y de sueño con el exceso de peso. Población y métodos. Para la medición de la actividad física y el sueño, se utilizaron acelerómetros ActiGraph wGT3X-BT®. Se determinó el índice de masa corporal para las categorizaciones de ausencia (peso normal) o presencia (sobrepeso-obesidad) de exceso de peso. Resultados. Participaron 183 escolares (54,1 % eran niñas, edad M = 10,95 ± 1,07). El 85,4 % no cumple con las recomendaciones de actividad física, mientras que el 75,6 % no cumple con las recomendaciones de sueño. Los niños se diferencian significativamente de las niñas en tiempo de actividades físicas moderadas y vigorosas (p = 0,002), mas no así en cantidad de sueño. Los escolares con exceso de peso presentan menos tiempo de actividades de intensidad moderada y vigorosa (p = 0,004) y una menor cantidad de sueño (p = 0,010) que los escolares de peso normal. El no cumplir las recomendaciones de actividad física se asociaría con el exceso de peso (razón de momios [OR, por su sigla en inglés] = 8,178; intervalo de confianza del 95 % [IC95 %]: 1,465-45,635; p = 0,017), lo que no se observó en las recomendaciones de sueño. Conclusiones. Un alto porcentaje de escolares no cumplen con las recomendaciones de actividad física y cantidad de sueño. Se observaron asociaciones según el sexo y la presencia de exceso de peso. Es necesario desarrollar estrategias para fomentar el cumplimiento de estas recomendaciones en la población infantil.

Summary School-based physical education (PE) is part of a whole-of-school approach to promote physical activity and its benefits for health. However, there are important gaps between the design and implementation of PE policies. This study aimed to describe the implementation fidelity and feasibility of school-based PE policies in Mexico. Data on implementation fidelity and feasibility was collected using semi-structured interviews (n = 17) and focus groups (n = 11) with high- (n = 7) and local-level (n = 122) stakeholders. We conducted a qualitative and triangulation content analysis. Feedback sessions were carried out with some participants. Barriers for implementation fidelity and feasibility of PE policies included inconsistencies in the time allocated to PE across schools and regions in the country; inconsistencies between teachers’ planning of PE classes and the actual class; a wide diversity of professional profiles among PE teachers; a limited number of PE professors, materials and facilities. To address these situations, some PE teachers were able to modify lesson plans and to design PE materials made from recycled materials. In conclusion, the current way in which school-based PE policies are being implemented in Mexico hinder PE from playing a major role in promoting physical activity among children and adolescents.

Background: The study summarizes the findings of the 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents and compares the results with the first Chilean RC and with other countries from the Global Matrix 3.0. Methods: A Research Work Group using a standardized methodology from the Global Matrix 3.0 awarded grades for 13 PA-related indicators based on the percentage of compliance for defined benchmarks. Different public data sets, government reports, and papers informed the indicators. Results: The grades assigned were for (1) “behaviors that contribute to overall PA levels”: overall PA, D−; organized sport participation, D−; active play, INC; and active transportation, F; (2) “factors associated with cardiometabolic risk”: sedentary behavior, C−; overweight and obesity, F; fitness, D; sleep, INC; and (3) “factors that influence PA”: family and peers, F; school, D; inclusion, INC; community and built environment, B; government strategies and investments, B−. Conclusions: Chile’s grades remained low compared with the first RC. On the positive side, Chile is advancing in environmental and policy aspects. Our findings indicate that the implementation of new strategies should be developed through collaboration between different sectors to maximize effective investments for increasing PA and decreasing sedentary time among children and adolescents in Chile.

The trajectory of aging is profoundly impacted by the physical and social environmental contexts in which we live. While “top–down” policy activities can have potentially wide impacts on such contexts, they often take time, resources, and political will, and therefore can be less accessible to underserved communities. This article describes a “bottom–up”, resident-engaged method to advance local environmental and policy change, called Our Voice, that can complement policy-level strategies for improving the health, function, and well-being of older adults. Using the World Health Organization’s age-friendly cities global strategy, we describe the Our Voice citizen science program of research that has specifically targeted older adults as environmental change agents to improve their own health and well-being as well as that of their communities. Results from 14 Our Voice studies that have occurred across five continents demonstrate that older adults can learn to use mobile technology to systematically capture and collectively analyze their own data. They can then successfully build consensus around high-priority issues that can be realistically changed and work effectively with local stakeholders to enact meaningful environmental and policy changes that can help to promote healthy aging. The article ends with recommended next steps for growing the resident-engaged citizen science field to advance the health and welfare of all older adults.

Global changes require urgent integration of health and wellbeing into all urban policies. Complex social and environmental factors define wellbeing outcomes and inequities present in cities. Additionally, political decisions are seldom thought and developed considering the needs and participation of children and adolescents. The REDibuja study aims to develop a multidimensional framework of wellbeing for children and adolescents and to validate an index of opportunities for better wellbeing for children and adolescents in the urban context of Temuco, Chile. This child-centered and cross-sectional study will involve mixed methodologies throughout the implementation of five work packages for two years (2022–2023): (1) development of a conceptual framework for child and adolescent wellbeing, (2) integration of available and public data, (3) studies in the local context, (4) data integration using geographic information systems, and (5) validation of the wellbeing opportunity index for children and adolescents. REDibuja will implement methodologies that until now are little used to facilitate political decisions in our regional context. This process and results could be transferred for assessment and decision-making in Latin America and low- and middle-income countries in other regions.

Background: Device measured physical activity (PA) allow better understanding on how PA is accrued during days. The purpose of this study was to describe pedometer-derived PA levels and patterns by gender in a population of Chilean children. Methods: 100 children were randomly selected from two low-income neighborhoods in Santiago, Chile. PA was measured with a wrist-worn pedometer for 7 consecutive days. Steps were summarized as total steps per hour and steps per day. PA hourly-patterns were compared across subgroups by age, gender, residence type and nutritional status. Results: 85 participants provided valid data (40 boys, 7.9±2.64 years, 47.8% overweight/obese). On an average day, children accumulated 11692.8±6061.8 steps with no differences between sexes (p=0.14). However, boys accumulated more steps in the morning and lunchtime than girls. Only 35.3% of the sample met PA guidelines (active), with no differences by sex (p=0.39). Active children in weekdays were more likely to meet the guidelines in weekend days (adjusted OR: 4.70, CI 95% 1.67-13.20) than those inactive in weekdays. Conclusion: PA guidelines compliance was relatively low. Step accumulation patterns differed between and within days including differences by gender in the morning and lunch time. This information may be used for designing feasible and equitable strategies for increasing the chances for meeting PA recommendations in both girls and boys. Resumen. Antecedentes: los métodos objetivos para medir la actividad física (AF) permiten una mejor comprensión de cómo se acumula la AF durante días. El propósito de este estudio fue describir los niveles y patrones de AF derivados del podómetro en una población de niños chilenos. Métodos: 100 niños participaron de dos barrios de bajos ingresos seleccionados al azar en Santiago de Chile. AF se midió con un podómetro de pulsera durante 7 días consecutivos. Los pasos se resumieron como pasos totales por hora y pasos por día. Los patrones de AF por hora se compararon entre los subgrupos por edad, sexo, tipo de residencia y estado nutricional. Resultados: 85 participantes proporcionaron datos válidos (40 niños, 7.9-2.64 años, 47.8% con sobrepeso / obesidad). En un día normal, los niños acumularon 11692.8±6061.8 pasos sin diferencias entre sexos (p = 0.14). Sin embargo, los niños acumularon más pasos en la mañana y mediodía que las niñas. Solo el 35.3% de la muestra cumplió con las recomendaciones de AF (activo), sin diferencias por sexo (p = 0.39). Los niños activos en los días de semana tenían más probabilidades de cumplir con las recomendaciones en los días de fin de semana (OR ajustado: 4.70, IC 95% 1.67-13.20) que los inactivos en los días de la semana. Conclusión: El cumplimiento de las recomendaciones de AF fue relativamente bajo. Los patrones de acumulación de pasos difieren entre y durante el día, incluyendo diferencias según sexo en relación a la acumulación de pasos en la mañana y almuerzo. Esta información puede ser utilizada para diseñar estrategias equitativas para aumentar las posibilidades de cumplir con las recomendaciones de AF tanto para niñas como para niños.

Accurate estimation of energy expenditure (EE) from accelerometer outputs remains a challenge in older adults. The aim of this study was to validate different ActiGraph (AG) equations for predicting EE in older adults. Forty older adults (age = 77.4 ± 8.1 yrs) completed a set of household/gardening activities in their residence, while wearing an AG at the hip (GT3X+) and a portable calorimeter (MetaMax 3B - criterion). Predicted EEs from AG were calculated using five equations (Freedson, refined Crouter, Sasaki and Santos-Lozano (vertical-axis, vectormagnitude)). Accuracy of equations was assessed using root-mean-square error (RMSE) and mean bias. The Sasaki equation showed the lowest RMSE for all activities (0.47 METs) and across physical activity intensities (PAIs) (range 0.18-0.48 METs). The Freedson and Santos-Lozano equations tended to overestimate EE for sedentary activities (range: 0.48 to 0.97 METs), while EEs for moderate-to-vigorous activities (MVPA) were underestimated (range: -1.02 to -0.64 METs). The refined Crouter and Sasaki equations showed no systematic bias, but they respectively overestimated and underestimated EE across PAIs. In conclusion, none of the equations was completely accurate for predicting EE across the range of PAIs. However, the refined Crouter and Sasaki equations showed better overall accuracy and precision when compared with the other methods.
