Physical Education for Health Among School-Aged Children and Adolescents: A Scoping Review of Reviews.

BACKGROUND: Physical education (PE) classes in schools are considered relevant to implement interventions, especially focused on physical activity. However, evidence overviews on how PE classes contribute to general health (physical, social, affective, and cognitive domains) are still needed. Thus, we summarized evidence synthesis (eg, systematic reviews) that addressed the contribution of PE classes to the health of school-aged children and adolescents. METHODS: We performed a scoping review with searches in 8 databases and institutional websites to find systematic reviews or meta-analyses that answered this review's research question. Data charting form included the identification of the study, health outcomes, and PE classes' strategies (policies and environment, curriculum, appropriate instructions, and evaluation). An interactive process was performed to build the evidence summary. RESULTS: An initial search yielded 2264 titles, and 49 systematic reviews (including 11 with meta-analysis) were included in this review. Most documents reported the main benefits of PE classes on physical domain outcomes (eg, physical activity, cardiorespiratory fitness, body mass index, and fundamental motor skills). However, evidence on the benefits of PE classes in affective (eg, enjoyment, motivation, and autonomy); social (eg, cooperation, problem-solving, and making friends); and cognitive (eg, memory, attention, concentration, and decision making) domains were found. Strategies on PE classes for health benefits were highlighted. CONCLUSIONS: These elements were detailed in the evidence summary, which may be considered to guide researchers, teachers, and practitioners to define research and practice priorities on PE class interventions for health in the school context.

Physical Activity Guidelines for the Brazilian Population: Development and Methods.

BACKGROUND: This article describes the process and methods used in the development of the first ever Physical Activity Guidelines for the Brazilian Population. METHODS: The steering committee established 8 working groups based on other guidelines and the Brazilian agenda for public health and physical activity (PA) promotion: (1) understanding PA; (2) children up to 5 years; (3) children and youth (6-17 y); (4) adults; (5) older adults (60 years and above); (6) physical education at school; (7) pregnant and postpartum women; and (8) people with disabilities. Working groups were formed to (1) synthesize the literature on each topic; (2) conduct workshops with stakeholders, health professionals, researchers, and the public; and (3) prepare a draft chapter for open online consultation. RESULTS: The document provides guidance for the population on the benefits of being active and recommendations regarding the amount (frequency, intensity, and duration) of PA recommended across all chapters. It also includes information on supporting networks for PA. CONCLUSIONS: The PA guidelines are widely accessible in Portuguese, including versions in English, Spanish, audiobook, and Braille, and will assist policy makers and professionals from several sectors to promote PA. The ultimate goal is to increase population levels of PA in Brazil.

Mapping recommended strategies to promote active and healthy lifestyles through physical education classes: a scoping review.

BACKGROUND: Understanding which strategies have been recommended for the promotion of active and healthy lifestyles through physical education (PE) classes can guide PE policies and practice. Therefore, we summarized worldwide recommendations regarding strategies for PE classes that have aimed to promote active and healthy lifestyles among school-aged children and adolescents. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines were utilized. A literature search was carried out in June 2020 in eight peer-reviewed literature databases, in addition to searches in institutional and personal libraries. The eligibility criteria included any online document that included recommendations targeting any dimension of PE classes (e.g., policy and environment, curriculum, appropriate instruction, student assessment, and strategies that interact with PE) published since 2000. RESULTS: In total, 2,408 potentially eligible documents were screened. Of these, 63 were included in the final analysis. The recommended strategies were as follows: six referred to policy and environment (valuing PE, higher frequency and duration of classes, inclusive PE classes, mandatory daily classes, evaluation of PE classes, and qualified teachers), five to curriculum (structure, type of content, cross-cutting themes, and components that improve PE classes), four to appropriate instruction (promotion of physical activities, inclusion of social issues, employment of the use of innovative technologies, and organization of the teaching-learning process), and three to student assessment (understanding human movement concepts, evaluation of contents, and assessment methods to develop an active and healthy lifestyle). CONCLUSION: Twenty-one strategies recommended for PE classes linked to five dimensions aimed at different target populations were identified. Over half were linked to the dimensions of policy and environment and appropriate instruction. PE is recommended to be mandatory and valued at all educational levels, with weekly frequency that contributes to an active and healthy lifestyle. This review shows that guaranteeing different experiences beyond sports, improving social inclusion, using innovative technologies, and providing adequate materials and spaces to be important challenges and ways to guide policies, programs, and new research in this field of knowledge.

Temporal Trends in Children's School Day Moderate to Vigorous Physical Activity: A Systematic Review and Meta-Regression Analysis.

BACKGROUND: Evidence from a limited sample of countries indicates that time for physical education and recess during school have declined. Schools are called to provide children with 30 minutes of moderate to vigorous physical activity (MVPA). This systematic review and meta-analysis estimated temporal trends in children's school day MVPA. METHODS: Three online databases were searched to identify studies with objectively measured MVPA, during school hours, in school aged children (5-18 y). Multilevel random-effects meta-analyses estimated MVPA by year, and meta-regression analyses estimated temporal trends in school day MVPA. RESULTS: Studies (N = 65) providing 171 MVPA estimates, representing 60,779 unique children, from 32 countries, and spanning 2003-2019 were identified. Most studies were conducted in North America (n = 33) or Europe (n = 21). School day MVPA ranged from 18.1 (95% confidence interval, 15.1-21.1) to 47.1 (95% confidence interval, 39.4-54.8) minutes per day in any given year. Meta-regression analyses indicated that MVPA declined from 2003 to 2010 (approximately 15 min decline), plateaued from 2010 to 2015 (approximately 1 min decrease), and increased from 2015 to 2019 (approximately 5 min increase). CONCLUSIONS: School day MVPA decreased from 2003 to 2010 and has recently begun to increase. However, the majority of the evidence is from North America and Europe with some evidence from Oceania and very little evidence from Asia to South America.

A estratégia LET US Play aumenta a atividade física de crianças nas aulas de educação física escolar / The LET US Play strategy increases children`s physical activity in physical education classes

O estudo objetivou comparar duas estratégias (Tradicional x LET US Play) com o intuito de aumen-tar o número de passos (NP) durante as aulas de educação física escolar de crianças. Trata-se de um ensaio clínico randomizado cruzado (cross over), realizado em uma escola municipal de Cuiabá, Mato Grosso. Foram aplicadas 10 aulas à 25 crianças (11 meninos e 14 meninas) do 4º ano do Ensino Fun-damental. Dividida em dois momentos de 15 minutos (monitorados), com um espaço de 10 minutos entre eles para hidratação (não monitorados), a aula consistia na aplicação das atividades (estafeta, base quatro, futsal, queimada e empresta bandeira) usando a estratégia Tradicional ou LET US Play, de forma alternada e aleatória. Ao final de cada atividade, o NP foi medido por meio da pulseira inteligente Xiaomi Mi band 2. Utilizou ANOVA One Waypara analisar o NP entre as estratégias, estratificada por sexo, com grau de significância de 5%. Observou-se que, o NP dados pelas crianças na intervenção LET US Play foi superior ao Tradicional em todas as atividades (estafeta, base quatro, futsal, queimada, empresta bandeira), tanto em meninos quanto em meninas, independentemente da ordem de aplicação (p < 0,01). Conclui-se que o LET US Play aumentou o NP das crianças durante as aulas de educação física e pode ser uma estratégia interessante para maximizar a atividade física nesse público

This study aimed to compare two strategies (Traditional x LET US Play) focused on increasing the number of steps (NS) during physical education classes for children. This is a randomized crossover clinical trial, carried out in a municipal elementary school from Cuiabá-MT. Ten classes were given to 25 children (11 boys and 14 girls) from the 4th grade. Divided into two moments of 15 minutes each (monitored), with a 10 minutes break between for hydration (not monitored). The class sessions consisted of activities (relay races, base four, futsal, dodgeball and borrow flag) using Traditional or LET US Play strategies, selected randomly and alternately. At the end of each activity the NS was measured through the Xiaomi Mi band 2 smart bracelet. The NP between the strategies and interactions with sex were assessed using one-way analysis of variance (ANOVA) with a statistical significance set at p < 0.05. It was observed that the NS given by the children in the LET US Play intervention was higher than the Traditional in all activities (relay races, kickball, indoor soccer, dodgeball, lend flag) in boys and girls regardless of the delivered order (p < 0,01). It was concluded that LET US Play increased children's NS during physical education classes and can be an interesting strategy to maximize physical activity among this population

Can physical education state policies impact on youth's health behaviors? A natural experiment study / Instrução normativa da educação física impacta nos comportamentos de saúde? Um experimento natural

Since 2011 an educational policy promulgated that public schools from Pernambuco have had to offer physical education (PE) class in the same shift where students are enrolled. This study examined the impact of the implementation of an educational policy on PE offering and students' participa-tion, and whether health related behaviors could be moderated by PE participation. It was a natural experiment study performed with data obtained from two cross-sectional studies (2007 and 2012) of a sample (n = 715) of high-school students from Caruaru. PE offering was assessed by asking students if they had PE class and adaptedquestionnairewas used to assess health-related informa-tion. It was observed that before policy implementation, most of the students (♂: 72.4%; ♀: 69.0%) was not engaged in any PE class during the week. After policy implementation the proportion of students who had at least one PE class/week increased (♂: 68.7%; ♀: 68.9%). Having ≥1 PE classes was not associated with the amount of physical activity either before (♂: OR = 1.47 (95%CI: 0.78 ­ 2.76)); ♀: OR = 1.02 (95%CI: 0.61­ 1.72) or after (♂: OR = 0.90 (95%CI: 0.51 ­ 1.58); ♀: OR = 1.06 (95%CI: 0.63 ­ 1.80)) policy implementation. Fruit consumption was the only health-related behavior associated to PE class (♂: OR = 1.55 (95%CI: 1.01 ­ 2.70); ♀: OR = 1.48 (95%CI: 1.02 ­ 2.10)). PE offering and participation of students improved and it seems that implementation of new policies for PE might impact on students' behaviors, although, regarding to some limitations, not sufficiently to impact on overall students' health behaviors

Desde 2011 uma instrução normativa estipulou que escolas públicas de Pernambuco ofertassem aulas de educação física (EF) no turno em que estudantes estão matriculados. Este estudo examinou o impacto dessa normativa na oferta de aulas de EF, na participação e sua associação com comportamentos de saúde dos estudantes. Tratou-se de um experimento natural realizado com dados de dois estudos transversais (2007 e 2012) de uma amostra (n = 715) de estudantes do ensino médio de Caruaru. A oferta de EF foi avaliada perguntando aos estudantes se eles tinham aula de EF, e um questionário adaptado foi utilizado para avaliar comportamentos de saúde. Verificou-se que antes da implementação da normativa a maioria dos estudantes não tinha aulas de EF (♂: 72,4%; ♀: 69,0%). Depois da implementação, a proporção de estudantes que tiveram uma aula de EF/semana aumentou (♂: 68,7%; ♀: 68,9%). Ter ≥1 aula de EF não foi associado o nível de atividade física em adolescentes antes (♂: RO= 1,47 (95%IC: 0,78­2,76); ♀: RO = 1,02 (95%IC: 0,61 ­ 1,72)) ou depois (♂: RO = 0,90 (95%IC: 0,51 ­ 1,58); ♀: RO = 1,06 (95%IC: 0,63 ­ 1,80)) da implementação. Consumo de frutas foi o único comportamento de saúde associado com as aulas de EF (♂: RO = 1,55 (95%IC: 1,01 ­ 2,70); ♀: RO = 1,48 (95%IC: 1,02 ­ 2,10). Após implementação da norma-tiva houve melhorias na oferta de aulas de EF e participação dos estudantes. Parece que isto pode impactar comportamentos de saúde em adolescentes, porém, devido limitações, é insuficiente para impactar os compor-tamentos de saúde no geral

Educação física escolar: Guia de Atividade Física para a População Brasileira / Physical Education: Physical Activity Guidelines for the Brazilian Population

As aulas de educação física (EF) escolar representam um momento propício para conhecer e viven-ciar a pluralidade do movimento humano, favorecendo a promoção de uma vida ativa e saudável. A importância da EF escolar foi reconhecida pelo Guia de Atividade Física para a População Brasileira (Guia), que dedicou um capítulo para orientar a comunidade escolar sobre os benefícios à saúde e as estratégias de sucesso adotadas nas aulas de EF escolar. O objetivo deste estudo é apresentar o processo de elaboração das recomendações brasileiras de EF escolar para a população brasileira, mais especificamente os estudantes, professores, pais e responsáveis, e gestores. Esse capítulo do Guia foi desenvolvido por dez pesquisadores brasileiros, incluindo um representante do Ministério da Saúde. Três sínteses de evidências, escutas ao público-alvo e consulta pública foram realizadas para a construção das recomendações. Dados de 49 revisões sistemáticas sobre os benefícios da EF escolar à saúde e de 22 intervenções nas aulas de EF escolar com estudantes brasileiros foram sumarizados. Ainda, foram sintetizados 63 documentos nacionais e internacionais com estratégias recomendadas para a EF escolar, com foco nas dimensões: política e ambiente; currículo; instrução apropriada; avaliação; e estratégias que interagem com a EF escolar. Os grupos focais e a consulta pública fun-damentaram a elaboração e o aprimoramento da versão final das recomendações. Espera-se que estas recomendações alicercem a criação de políticas públicas, melhorem a conscientização sobre a importância da prática de atividade física na EF escolar e enfatizem a necessidade de realizar estudos futuros nesta área de conhecimento

Physical Education (PE) classes represent an appropriate time to know and experience the plurality of the human movement, favoring the promotion of a healthy and active life. The importance of PE was recognized by the Physical Activity Guide for the Brazilian Population, which dedicated a chapter to guide the school community on the health benefits and successful strategies adopted in PE classes. This study aimed to show the process of elaborating Brazilian recommendations for PE for the Brazilian population, more specifically students, teachers, parents and guardians, and managers. This chapter of the Guide was developed by ten Brazilian researchers, including a spokeswoman of the Ministry of Health. Three syntheses of evidence, focus groups/interviews and public consultation were carried out to construct the recommendations. Data from 49 systematic reviews on the health benefits of PE and 22 interventions in PE classes with Brazilian students were summarized. Also, 63 documents were synthesized with strategies recommended for PE classes, focusing on the dimensions: politics and environment; curriculum; appropriate instruction; evaluation; and strategies that interact with PE. The focus groups and the public consultation were the basis for the elaboration and improvement of the final version of the recommendations. It is expected that these recommendations can assist the creation of public policies, the improvement of practice PE and the need to conduct future studies in this area of knowledge

Children's moderate-to-vigorous physical activity on weekdays versus weekend days: a multi-country analysis.

PURPOSE: The Structured Days Hypothesis (SDH) posits that children's behaviors associated with obesity - such as physical activity - are more favorable on days that contain more 'structure' (i.e., a pre-planned, segmented, and adult-supervised environment) such as school weekdays, compared to days with less structure, such as weekend days. The purpose of this study was to compare children's moderate-to-vigorous physical activity (MVPA) levels on weekdays versus weekend days using a large, multi-country, accelerometer-measured physical activity dataset. METHODS: Data were received from the International Children's Accelerometer Database (ICAD) July 2019. The ICAD inclusion criteria for a valid day of wear, only non-intervention data (e.g., baseline intervention data), children with at least 1 weekday and 1 weekend day, and ICAD studies with data collected exclusively during school months, were included for analyses. Mixed effects models accounting for the nested nature of the data (i.e., days within children) assessed MVPA minutes per day (min/day MVPA) differences between weekdays and weekend days by region/country, adjusted for age, sex, and total wear time. Separate meta-analytical models explored differences by age and country/region for sex and child weight-status. RESULTS/FINDINGS: Valid data from 15 studies representing 5794 children (61% female, 10.7 ± 2.1 yrs., 24% with overweight/obesity) and 35,263 days of valid accelerometer data from 5 distinct countries/regions were used. Boys and girls accumulated 12.6 min/day (95% CI: 9.0, 16.2) and 9.4 min/day (95% CI: 7.2, 11.6) more MVPA on weekdays versus weekend days, respectively. Children from mainland Europe had the largest differences (17.1 min/day more MVPA on weekdays versus weekend days, 95% CI: 15.3, 19.0) compared to the other countries/regions. Children who were classified as overweight/obese or normal weight/underweight accumulated 9.5 min/day (95% CI: 6.9, 12.2) and 10.9 min/day (95% CI: 8.3, 13.5) of additional MVPA on weekdays versus weekend days, respectively. CONCLUSIONS: Children from multiple countries/regions accumulated significantly more MVPA on weekdays versus weekend days during school months. This finding aligns with the SDH and warrants future intervention studies to prioritize less-structured days, such as weekend days, and to consider providing opportunities for all children to access additional opportunities to be active.

Effects of a teacher training intervention on teachers' and students' motivation to physical education class / Efeitos de uma intervenção de formação de professores na motivação de professores e alunos para a aula de educação física

ABSTRACT The present study evaluated the effects of a teacher training intervention, based on Self-Determination Theory, on teachers' and students' motivation in physical education class. This is a pre-post quasi-experimental study with 4 physical education teachers and 611 students from four public schools. A handbook was developed and teacher training sessions were conducted. Statistical analysis consisted of paired t-tests and general linear model repeated measures to assess teachers' self-determined motivation and linear mixed effect regression to evaluate students' motivation. A significant increase in teachers' and students' motivation score was observed after the intervention. Among teacher, we verified an increase in self-determined motivation. Among students there were significant interaction time by group in Extrinsic Motivation Identified Regulation (F=5.6), Extrinsic Motivation External Regulation (F=7.41), Amotivation (F=5.32) and Self-determined Motivation (F=4.87). Also, Intrinsic Motivation significantly declined with age for boys (β= -0.151) and girls (β= -0.121) as well as Extrinsic Motivation Introjected Regulation for girls β= (-0.141). Training sessions can support teachers in planning lessons resulting in increasing teacher and students' motivation in physical education classes. However, this strategy was not enough to improve intrinsic motivation during the investigated period.

RESUMO O presente estudo avaliou os efeitos de uma intervenção com professores, baseada na Teoria da Autodeterminação, sobre a motivação de professores e alunos para a aula de educação física (EF). É um estudo quase-experimental do tipo antes e depois com 4 professores de EF e 611 alunos. Foi elaborado um manual e realizadas sessões de formação de professores. Análise estatística incluiu testes t pareados e medidas repetidas através do modelo linear geral e da regressão linear de efeito misto. Um aumento significante no escore de motivação de professores e alunos foi observado após a intervenção. Entre os professores verificou-se um aumento na motivação auto-determinada. Entre os alunos houve interação significante entre tempo por grupo (Motivação Extrínseca Regulação Identificada (F=5,6), Motivação Extrínseca Regulação Externa (F=7,41), Amotivação (F=5,32) e Motivação Autodeterminada (F=4,87). Além disso, a Motivação Intrínseca diminuiu significantemente com a idade para rapazes (β= -0.151) e moças (β= -0.121), bem como a Motivação Externa Regulação Introjetada para moças (β= -0.141). Sessões de formação podem apoiar os professores no planejamento resultando no aumento da motivação dos professores e alunos nas aulas de EF. No entanto, esta estratégia não foi suficiente para melhorar a motivação intrínseca no período investigado.

Physical activity and sedentary time of youth in structured settings: a systematic review and meta-analysis.

BACKGROUND: Structured settings, such as school, childcare, afterschool programs, summer camps, and physical activity/sport programs are crucial to promoting physical activity (PA) opportunities and reducing sedentary (ST) for children and adolescents. However, little is known about how much PA and ST children and adolescents accumulate in structured settings. The aim of this study is to conduct a systematic review and meta-analysis of the absolute amount of time youth spend physically active and sedentary in different structured settings (Prospero number: 42018111804). METHODS: Observational and experimental/quasi-experimental studies (baseline data only) with full-text available, written in English and published in a peer-reviewed journal, reporting the total amount of objectively measured PA (light, moderate, vigorous, and/or total physical activity) and/or time spent ST during structured settings among youth (3 to 18 years) were eligible. Adjusted meta-analysis was conducted to estimate the pooled mean of time spent in PA and ST, by settings and sex. RESULTS: A total of 187 studies (childcare n=60; school n=91; afterschool programs n=14; summer camp n=4; and Physical activity/ sport programs n=18) from 30 countries (47.9% United States), representing 74,870 youth (mean age 8.6 years old) were included. Overall, there was a high variation between studies in outcomes and settings. The meta-analyses revealed, on average, youth spend 221.8 minutes (36.7 min/hour) in ST and 32.1 minutes (5.1 min/hour) in MVPA during childcare hours, and 223.9 minutes (36.7min/hour) in ST and 27.8 min (4.4 min/hour) in MVPA at school. Relatively, youth are engaged in more MVPA in afterschool programs (11.7 min/hour), PA/ sport programs (20.9 min/hour), and summer camps (6.4 min/hour), when compared to childcare and school. CONCLUSION: Total PA accumulated during childcare and MVPA accumulated during schools hours were close to recommendations, despite high proportion of ST. Afterschool programs, summer camp and PA/ sport programs are important settings that can contribute to daily PA and reduced ST. Ensuring all youth have access to these structured settings may be an important step forward for public health.

Research on the Academia da Cidade and Academia da Saúde Programs: scoping review / Pesquisas sobre os Programas Academia da Cidade e Academia da Saúde: revisão de escopo

In order to identify the research that addressed the Academia da Cidade and Academia da Saúde Programs (ACP/ASP), a scoping review was conducted in April 2020 in five electronic databases and in reference lists aiming to identify scientific articles that had data collections carried out in the facilities of the ACP/ASP or, that somehow involved the populations of the localities where the programs were implemented. Of the 321 initial records, the descriptive synthesis consisted of 59 studies, which had as their most frequent characteristics: cross-sectional design, use of quantitative approaches in data collection and analysis, Nutrition as a central topic, and involvement of users (adults and the elderly). In conclusion, longitudinal studies involving all actors (managers, practitioners and users) and covering different health topics, besides promoting the approximation between academia and decision makers, may be promising in the sense of better evaluating the impact that the program represents in the life of the communities that are attended

No sentido de identificar as pesquisas que abordam os Programas Academia da Cidade e Academia da Saúde (PAC/PAS), em abril de 2020 foi conduzida uma revisão de escopo, em cinco bases de dados eletrônicas em listas de referências, a fim de identificar artigos científicos originais que tiveram coletas de dados realizadas nas instalações do PAC/PAS ou, que, de alguma forma envolveram as populações das localidades em que foram implantados os programas. De 321 registros iniciais, a síntese foi composta por 59 artigos científicos, que apresentaram como características mais frequentes: delineamento transversal, uso de abordagens quantitativas nas coletas e análises de dados, Nutrição como temática central e envolvimento de usuários (adultos e idosos). Em conclusão, estudos longitudinais envolvendo todos os atores (gestores, profissionais e usuários) e distintas temáticas da saúde, além de promoverem a aproximação entre a academia e tomadores de decisão, podem ser promissores no sentido de melhor avaliar o impacto que o programa representa na vida das comunidades que são atendidas

Sleep, sedentary behavior and physical activity: changes on children's routine during the COVID-19 / Sono, comportamento sedentário e atividade física: mudanças na rotina de crianças durante a COVID-19

Social isolation was adopted as a strategy to reduce the transmission speed of the severe acute respiratory syndrome of coronavirus 2 (SARS-CoV-2) in several countries in the world, including Brazil. As a result, schools were closed and the routines of children altered, affecting sleep, sedentary behavior, and physical activity. The present study aims to compare the children's weekly routine and time spent on sleep, sedentary behavior and physical activity before and during the Coronavirus disease 2019 (COVID-19) pandemic. A cross-sectional study with a quantitative and qualitative approach was performed, with 120 parents, mothers or guardians of children from 5 to 10 years of age of both sexes enrolled in 5 full-time schools in Arapiraca, Alagoas, Brazil. To meet the research objective, two interviews were conducted between 27 May and 5 June, out addressing aspects of sleep, sedentary behavior, and physical activity before and during the COVID-19 pandemic. In the analysis of quantitative data, the paired sample t test was performed, while for qualitative data, discourse analysis was used. Significant differences (p < 0.05) were found in the routine and in sleep time (increase 10%) and screen time (increase 36%) before vs during the COVID-19 pandemic, on weekdays and weekends. There was also a reduction in the practice of physical activity (54%). Therefore, the findings indicate that behaviors during the COVID-19 pandemic could be harmful to children's health and that the school may be an important social environment to protect children from exposure to these behaviors

O isolamento social foi adotado como estratégia para reduzir a velocidade de transmissão da síndrome respiratória aguda grave de coronavírus 2 (SARS-CoV-2) em vários países do mundo, incluindo o Brasil. Como resultado, as escolas foram fechadas e as rotinas das crianças alteradas, afetando o sono, o comportamento sedentário e a atividade física. O presente estudo tem como objetivo comparar a rotina semanal das crianças e o tempo dispendido em sono, comportamento sedentário e atividade física antes e durante a pandemia da doença coronavírus 2019 (COVID-19). Estudo de caráter transversal e com abordagem quanti-qualitativa, com 120 pais, mães ou responsáveis de crianças de 5 a 10 anos de ambos os sexos, matriculadas em 5 escolas de tempo integral de Arapiraca, Alagoas, Brasil. Foram realizadas duas entrevistas, no período de 27 de Maio à 05 de Junho, abordando os aspectos do sono, comportamento sedentário e atividade física antes e durante a pandemia, a fim de atender o objetivo de pesquisa. Na análise dos dados quantitativos foi realizado o teste t de amostra emparelhada, já para os dados qualitativos foi utilizada a análise do discurso. Foram encontradas diferenças significativas (p < 0,05) na rotina e no tempo de sono (aumento de 10%), no tempo de tela (aumento de 36%) antes vs durante a pandemia de COVID-19, em dias de semana e finais de semana. Foi observada também uma redução na prática de atividade física (54%). Portanto, os achados indicam comportamentos durante a pandemia de COVID-19 que podem ser prejudiciais à saúde das crianças e a escola pode ser um ambiente social importante na proteção a exposição de tais condutas

Clusters of non-dietary obesogenic behaviors among adolescents in Brazil: a latent profile analysis.

OBJECTIVES: To identify patterns of non-dietary obesogenic behaviors, and social and environmental factors associated with overweight and obesity (OWOB). METHODS: A representative sample (n = 5520) of high school students (55.4% girls, 16.3 ± 1.0 years) from Pernambuco State, Brazil. Latent profile analyses were performed using self-reported daily sleep duration, television use, computer use, videogame use, seated time during the week and weekend days, physical activity, and active commuting to school during the week. Social and environmental factors and body mass index were included to identify classes. Multinomial analysis explored differences in social, environmental factors, and BMI by classes. RESULTS: Five patterns were identified [Computer users (C1), Short sleepers (C2), Typical behaviors (C3), Techno-active-gamers (C4), and Lower screen engagement (C5)]. Three groups (C1, C3 and C4) included students from better social conditions and a more urbanized environments. The prevalence of OWOB was higher in C1 (34.5%; 95% CI 31.1-38.0) and in C2 (29.7%; 95% CI 26.1-33.5) compared to C5 (23.3% 95% CI 21.3-25.3). CONCLUSIONS: In one of the poorest regions of Brazil, different groups of social/environmental factors and behavior patterns emerged associated with OWOB.

Validação do Perceived Locus Of Causality Questionnaire para avaliação da motivação nas aulas de Educação Física / Validation of Perceived Locus Of Causality Questionnaire for motivation assessment on Physical Education classes

A Educação Física possui um papel central durante os anos escolares, pois a participação de forma regular pode proporcionar, dentre outros, benefícios biológicos, psicológicos e acadêmicos. Conhecer a motivação dos estudantes pode contribuir no planejamento de estratégias para melhorar a participação nas aulas. Para o conhecimento da motivação faz-se necessário à utilização de instrumentos, que muitas vezes não são validados para a população a qual se quer investigar, dificultando assim a comparação dos resultados obtidos. O presente estudo teve como objetivo realizar a adaptação transcultural e avaliar as propriedades psicométricas do Perceived Locus of Causality Questionnaire (PLOCQ) que visa medir as dimensões motivacionais definidas em um continuum da Teoria da Autodeterminação para articipação nas aulas de Educação Física Escolar. As etapas de validação foram: tradução do instrumento, retro-tradução, revisão técnica e avaliação da equivalência semântica, validação do conteúdo, avaliação do instrumento pelos especialistas e população-alvo e avaliação das propriedades psicométricas. O instrumento foi aplicado a 464 estudantes (58,4% de moças) do ensino médio com idade entre 13 e 17 anos. Foram realizadas a adaptação transcultural e avaliação das propriedades psicométricas por meio da reprodutibilidade, análise de consistência interna, análise fatorial exploratória (AFE) e confirmatória (AFC). Os itens da escala apresentaram boa consistência interna com variação do coeficiente α de Cronbach de 0,71 a 0,79 e boa reprodutibilidade teste-reteste (Kappa entre 0,61 a 0,88). A análise fatorial exploratória identificou cinco componentes e vinte itens que explicaram 57,9% da variância do questionário. O modelo final da análise fatorial confirmatória foi significativo (RMSEA de 0,071; GFI de 0,91, RMSR de 0,04 e CFI de 0,95). O instrumento poderá ser utilizado, com um elevado grau de confiança, em futuras investigações que pretendam avaliar a motivação dos estudantes no contexto das aulas de Educação Física no Brasil...(AU)

The physical education class has a central role during scholar years because a regular participation could provide among others biological, psychological and academic benefits. Knowing student motivation can contribute to planning strategies to improve participation in class. To know the motivation, it is necessary to use instruments, which are often not validated for the target population, making it difficult to compare the results obtained. The objective of this study was to translate and perform a cross-cultural adaptation and analyze psychometric properties of the Perceived Locus of Causality Questionnaire (PLOCQ) that aims to measure the motivational dimensions forms defined on a continuum of Self-determination Theory for participation in physical education classes. The validation stages were translation of the instrument, back translation, technical review and evaluation of semantic equivalence, validation of content, evaluation of the instrument by specialists and target population and evaluation of psychometric properties. This instrument was administered to 464 high school students (58.4% female) aged 13 to 17 years. The stages of cultural adaptation were conducted as well as evaluation of the psychometric properties through reproducibility, internal consistency and exploratory factor analysis. The items of the scale showed good internal consistency with coefficient α Cronbach ranging from 0.71 to 0.79 and good test-retest reproducibility (Kappa coefficient ranged from 0.61 to 0.88). Exploratory factor analysis identified five components that explained 57.9% of the variance of the questionnaire items. The final model of confirmatory factor analysis was significant (RMSEA of 0.071, GFI of 0.91, RMSR of 0.04 and IFC of 0.95). We conclude that this tool can be used with a high degree of confidence in future investigations aiming to assess the student motivation in the context of physical education classes in Brazil...(AU)

Participação de adolescentes brasileiros nas aulas de educação física escolar: revisão sistemática / Participation of brazilian adolescents in school physical education classes: systematic review / Participación de adolescentes brasileños en las clases de educación física escolar: revisión sistemática

Identificar e comparar artigos sobre a participação de adolescentes brasileiros nas aulas de Educação Física (EF) e verificar os fatores associados constituem os objetivos deste trabalho. O método utilizado foi busca sistematizada da literatura nas bases: MEDLINE, Scielo, LI-LACS, Google acadêmico, ERIC, CAPES e Adolec. Disso, dez estudos foram incluídos, sen-do 70% realizados no Nordeste e 100% utilizaram questionário. A participação variou de 29,3 a 75,0%. A variável comportamental associada à participação mais avaliada foi a prática de atividadefísica. Portanto, conclui-se que poucos estudos foram realizados, sendo a maioria deles no Nordeste. Dado isso, este trabalho incentiva a produção de estudos em outras regiões do Brasil, a utilização de outros instrumentos, a investigação dos fatores associados e a identi-ficação dos motivos que levam à participação nas aulas de EF.

Screen time, physical activity and cardiovascular risk factors in adolescents / Tempo de tela, atividade física e fatores de risco cardiovasculares em adolescentes

The aim of this study was to examine the independent and combined associations of physical activity and different types of screen time in cardiovascular disease risk factors in adolescents. The sample was comprised for 1,045 adolescents (51.7% female) aged 11-17 years old randomly selected. Screen time was considered by the self-related electronic devices such as time watching TV, using computer (PC) and playing videogame (VG). Physical activity was estimated by the number of steps per day (steps/day) measured by pedometers. Cardiovascular risk factors were sum of triceps and subscapular skin-folds (∑SF), total cholesterol (TC) and blood pressure (BP). Predictors and outcome variables were dichotomized using standardized cut off points. Categories of steps/day and different types of screen time were cross tabulated to the combined analyses. A set of sociodemographic variables was used as confounders. To test the independent and combined associations Chi-square tests (unadjusted) and binary logistic regression (adjusted) were used. TV time was directly and independently associated to ∑SF in females and to TC in males. Steps/day was inversely and independently associated to TC and to BP (not in female). Overall, combined analyses showed that adolescents who did not meet recommendations of steps/day and exposure an excessive screen time are more likely to present car-diovascular risk factor. Public health programs to increase physical activity and reduce screen time, especially TV time, should be developed to improve and prevent cardiovascular health in adolescents

O objetivo deste estudo foi identificar as associações independentes e combinadas da atividade física e de diferentes tipos de tempo de tela com fatores de risco para doenças cardiovasculares (DCV ) em adolescentes. A amostra foi composta por 1.045 adolescentes (51,7% meninas) de 11 a 17 anos de idade selecionados aleato-riamente. O tempo de tela (TT) foi considerado a partir do autorrelato do tempo de médio diário assistindo TV, e usando computador (PV ) e jogando videogame ( VG). A atividade física foi estimada pelo número de passos (passos/dia) medido por pedômetros. Os fatores de risco para DCV foram o somatório de dobras cutâneas (∑DC), colesterol total (CT) e pressão arterial (PA). Preditores e desfechos foram dicotomizados usando pontos de corte padronizados. As categorias do passos/dia e TT foram combinadas. Diferentes variá-veis sociodemográficas foram utilizadas como variáveis de ajuste. Para testar as associações independentes e combinadas foram utilizados teste qui-quadrado (brutas) e a regressão logística binária (ajustada). O tempo de TV se associou direta e independentemente com o ∑DC nas meninas e com o CT nos meninos. Os passos/dia se associou inversa e independentemente com o CT e a PA (meninos). De maneira geral, as análises combinadas mostraram que adolescentes que não atendem as recomendações para passos/dia e TT apresen-tam probabilidade aumentada de estarem expostos a fatores de risco para doenças CDV. Programas de saúde pública para o aumento da atividade física e redução do tempo de tela, principalmente o tempo de TV, devem ser desenvolvidos para prevenção da saúde cardiovascular de adolescentes

Validation of psychosocial scales for physical activity in university students.

OBJECTIVE Translate the Patient-centered Assessment and Counseling for Exercise questionnaire, adapt it cross-culturally and identify the psychometric properties of the psychosocial scales for physical activity in young university students. METHODS The Patient-centered Assessment and Counseling for Exercise questionnaire is made up of 39 items divided into constructs based on the social cognitive theory and the transtheoretical model. The analyzed constructs were, as follows: behavior change strategy (15 items), decision-making process (10), self-efficacy (6), support from family (4), and support from friends (4). The validation procedures were conceptual, semantic, operational, and functional equivalences, in addition to the equivalence of the items and of measurements. The conceptual, of items and semantic equivalences were performed by a specialized committee. During measurement equivalence, the instrument was applied to 717 university students. Exploratory factor analysis was used to verify the loading of each item, explained variance and internal consistency of the constructs. Reproducibility was measured by means of intraclass correlation coefficient. RESULTS The two translations were equivalent and back-translation was similar to the original version, with few adaptations. The layout, presentation order of the constructs and items from the original version were kept in the same form as the original instrument. The sample size was adequate and was evaluated by the Kaiser-Meyer-Olkin test, with values between 0.72 and 0.91. The correlation matrix of the items presented r < 0.8 (p < 0.05). The factor loadings of the items from all the constructs were satisfactory (> 0.40), varying between 0.43 and 0.80, which explained between 45.4% and 59.0% of the variance. Internal consistency was satisfactory (α ≥ 0.70), with support from friends being 0.70 and 0.92 for self-efficacy. Most items (74.3%) presented values above 0.70 for the reproducibility test. CONCLUSIONS The validation process steps were considered satisfactory and adequate for applying to the population.

Os construtos analisados foram: estratégia de mudança de comportamento (15 itens), processo de tomada de decisão (10), autoeficácia (seis), apoio da família (quatro) e dos amigos (quatro). Os procedimentos de validação foram de equivalências conceitual, de itens, semântica, operacional, de mensuração e funcional. As três primeiras equivalências citadas foram realizadas por comitê especializado. Na equivalência de mensuração, o instrumento foi aplicado em 717 estudantes universitários. Foi utilizada análise fatorial exploratória para verificar a carga de cada item, variância explicada e consistência interna dos construtos. A reprodutibilidade foi mensurada por meio de correlação intraclasse.RESULTADOS As duas traduções se mostraram equivalentes, a retrotradução foi semelhante à versão original, sendo realizadas poucas adaptações. Foram mantidos o mesmo layout, ordem de apresentação dos construtos e dos itens que compunham o instrumento original. O tamanho da amostra foi adequado e avaliado pelo teste de Kaiser-Meyer-Olkin, com valores entre 0,72 e 0,91. A matriz de correlação dos itens apresentou r < 0,8 (p < 0,05). As cargas fatoriais dos itens de todos os construtos foram satisfatórias (> 0,40), com variação entre 0,43 e 0,80, explicando entre 45,4% a 59,0% da variância. A consistência interna foi satisfatória (α ≥ 0,70), sendo 0,70 para apoio dos amigos e 0,92 para autoeficácia. A maioria dos itens (74,3%) apresentou valores acima de 0,70 para o teste de reprodutibilidade.CONCLUSÕES As etapas do processo de validação foram satisfatórias e consideradas adequadas para aplicação na população.
