Are low-income preschoolers physically active at preschool settings? A cross-sectional study.

BACKGROUND: Preschools may provide opportunities for children to engage in physical activity (PA), to benefit their health, although little is known when concerning low-income preschoolers. This study aimed (1) to describe time spent in PA among low-income children during preschool hours and (2) to analyse how many children meet the PA recommendations during preschool hours. METHODS: A total of 204 low-income preschoolers (4.51 ± 0.79 years) from João Pessoa/Brazil provided valid accelerometer (Actigraph, WGT3-X) data during the preschool period. Children were grouped in quartiles of PA in counts per minute, according to sex and age. The General Linear Model Univariate was used to examine the differences in PA intensities between the quartiles and the time spent in total PA (TPA) and moderate-to-vigorous PA (MVPA) by quartiles, according to age. An hour-by-hour description of children's PA was presented. RESULTS: TPA during preschool hours ranged from 68.33% to 113.89% of the recommended and from 28.34% to 81.68% of the MVPA recommendations. Among 5-year-old children, those in the highest quartile met the PA recommendations. All children were more active outdoors than indoors. For the less actives, preschool time corresponded to 30% of the recommended daily MVPA. CONCLUSION: The current results reinforce the importance of preschool settings for promoting preschoolers' PA and provide particularly important and useful information for tailoring preschool-based interventions focused on those who need it most. Strategies to increase children's MVPA should be prioritized during free-play time.

Associação entre parâmetros do sono e atividade física em corredores durante a pandemia de COVID-19 / Association between sleep parameters and physical activity in runners during the COVID-19 pandemic

Determinar associação entre qualidade do sono (QS), sonolência diurna excessiva (SDE) e a atividade física (AF) em corredores de rua durante a pandemia deCOVID-19. Em86 voluntários, as seguintes variáveis foram avaliadas: QS (pelo Índice de Qualidade do Sono de Pittsburgh, ESE (pelaEscala de Sonolência de Epworth) e a AF (pelo aplicativo Google Fit®).Utilizou-se o teste de correlação de Pearson ou teste de correlação de Spearman. A análise de regressão linear simples foi realizada entre as variáveis que apresentaram correlação. Consideraram-se significantes os valores de p<0,05. Houve correlação entre a SDE e a contagem de passos, bem como entre a SDE e a AF. Verificou-se associação entre a SDE e a AF, mas não entre a QS e a AF.

To determine the association between sleep quality (SQ), excessive daytime sleepiness (EDS) and physical activity (PA) in amateur street runners during the COVID-19pandemic. Eighty-six volunteers were evaluated, and the analyzed variables were: SQ (By Pittsburgh Sleep Quality Index), EDS (By Epworth Sleepiness Scale), and PA (By the Google Fit® app). The data was collected remotely, via email, using Google Forms. Pearson correlation test or Spearman correlation test was used for data correlation. Simple linear regression analysis was performed between variables that showed correlation. P values < 0.05 were considered significant. There was a correlation between EDS and step count [r (p) = 0.219 (0.042)], and only an association between PA and EDS was observed. Based on the results, an association was found between EDS and PA. However, no association was found between SQ and PA.

Physical activity, sedentary behavior and sleep measured by smartwatch: a scoping review protocol / Atividade física, comportamento sedentário e sono medidos por smartwatch: protocolo de revisão de escopo

The health impacts of physical activity (PA), sedentary behavior (SB), and sleep are well established; thereby, the identification of instruments to assess and monitor these behaviors at a populational lev-el is relevant. In this context, smartwatches, which are wristwatch-shaped devices equipped with sen-sors, have been identified as alternatives for objectively measuring PA, SB, and sleep. Therefore, this protocol aimed at describing the goals and methods of a scoping review to map the literature on the use of smartwatches to objectively measure PA, SB, and/or sleep across the lifespan (e.g., children, adolescents, adults, and elderly) and in different contexts. Studies will be included if they use smart-watches to objectively measure at least one of the behaviors (PA, SB, and sleep) in children, adoles-cents, adults, and older adults, published after 2013. No language filter will be applied. Searches will be carried out in six databases (Pubmed/Medline, Scopus, Web of Science, LILACS, IEEE Xplore Digital Library, Scielo, Health Technology Assessment Database, and Cochrane clinical trials) and two clinical trial repositories. The screening and data extraction will be performed independently by two authors who had previous experience in reviews and technologies. The synthesis of the results will follow the Joanna Briggs Institute framework for extracting the results in scoping reviews. The results can contribute to scientific progress by identifying gaps and research trends, guiding future studies, and informing companies, healthcare professionals, and the general public who use smart-watch as a measurement tool for physical activity, sedentary behavior, and sleep

Os impactos da atividade física (AF), comportamento sedentário (CS) e sono na saúde são bem estabelecidos, tornando-se relevante identificar instrumentos que permitam avaliar e monitorar esses comportamentos em nível populacional. Nesse contexto, os smartwatches, que são dispositivos em formato de relógio de pulso, com-postos por sensores, tem sido apontado como alternativa para mensurar objetivamente AF, CS e sono. Portanto, o objetivo deste protocolo foi descrever os objetivos e métodos de uma revisão de escopo para mapear a literatura científica sobre o uso de smartwatches para medir objetivamente AF, CS e/ou sono em diferentes populações e contextos. Os estudos serão incluídos se usarem smartwatches para medir objetivamente pelo menos um dos comportamentos (AF, CS e sono) em crianças, adolescentes, adultos e idosos, publicados após 2013. Nenhum filtro de idioma será aplicado. As buscas serão realizadas em sete bases de dados (Pubmed/Medline, Scopus, Web of Science, IEEE Xplore Digital Library, Scielo, LILACS, Health Technology Assessment Database e Cochrane Clinical Trials) e dois repositórios de ensaios clínicos. A triagem e extração dos dados serão realizadas de forma independente por dois autores com experiência prévia em revisões e tecnologias. A síntese dos resultados seguirá o framework do Joanna Briggs Institute para extração dos resultados nas revisões de escopo. Os resultados podem contribuir para o progresso científico, identificando lacunas e tendências de pesquisa, orientando futuros estudos, empresas que atuam neste mercado, profissionais de saúde e o público em geral que utilizam smartwatch como um instrumento de medição para atividade física, comportamento sedentário e sono

A Study on the Health and Wellness of Undergraduate Students (SABES-Grad): methodological aspects of a nationwide multicenter and multilevel study overlapping with the Covid-19 pandemic.

INTRODUCTION: The academic environment can negatively impact the mental health of undergraduate students, particularly in the context of the coronavirus disease 2019 (Covid-19) pandemic. This study aimed to describe the methodological and operational aspects of a study of the health and well-being of undergraduate students: the Study on the Health and Wellness of Undergraduate Students (SABES-Grad) project. METHOD: This was a nationwide cross-sectional study divided across two data collection strategies: a single-center, on-site data collection carried out in 2019 at the Universidade Federal do Rio Grande (FURG) and a multicenter, multilevel, online data collection carried out in 2020/2021 at FURG, the Universidade Federal Fluminense (UFF), the Universidade Federal do Mato Grosso (UFMT), the Universidade do Estado do Amazonas (UEA), and the Universidade Federal Rural de Pernambuco (UFRPE). The main outcomes of interest were depressive symptoms, generalized anxiety, and suicide risk. RESULTS: A total of 996 students participated in the 2019 data collection (63.8% female; median age of 22 years; response rate of 85.2%) and 5,720 students participated in the 2020/2021 collection (66.7% female; median age of 22 years; response rate of 84.3%). Significant variations in socioeconomic and demographic profiles were observed between the different universities. Approximately one-third of the sample had been tested for Covid-19 in 2020/2021, 7.8% of whom had tested positive. CONCLUSION: The SABES-Grad project was the result of collaborative work between several actors from public universities in Brazil. Several aspects of the preparation and execution of this research are discussed in terms of its originality and relevance. Barriers and limitations and strategies adopted to overcome them are also presented.

Suicide risk among undergraduate students in Brazil in the periods before and during the COVID-19 pandemic: results of the SABES-Grad national survey.

BACKGROUND: Undergraduate students present high rates of psychological distress, including suicide risk. Due to the coronavirus disease 2019 (COVID-19) pandemic, this scenario may have been aggravated. Thus, the objective of the current study was to evaluate changes in the suicide risk rate from the period before to during the COVID-19 pandemic, as well as the factors associated with this outcome among Brazilian undergraduate students. METHODS: This was a nationwide survey carried out in Brazil with a cross-sectional design, including two data collection periods: a single-center in-person collection in 2019 and another multicenter online collection in 2020/2021. Data were collected using self-administered instruments. The outcome was a high risk of suicide, measured through the Mini International Neuropsychiatric Interview. Analyses were carried out on data from two periods, i.e. before and during the pandemic (bivariate analysis and interaction tests), and a model of associated factors (multivariate analysis using Poisson regression) was developed including all participating universities distributed in the five regions of Brazil. RESULTS: In total, 6716 Brazilian undergraduate students participated (996 in 2019 and 5720 in 2020/2021). The prevalence of a high suicide risk rose from 11.3% to 17.0%, especially among women and poorer individuals. The prevalence of a high risk of suicide among Brazilian undergraduates was 19.6% and was associated with several socioeconomic, academic, pandemic, and mental health factors. CONCLUSIONS: The prevalence of a high suicide risk increased from prepandemic to during the pandemic, appearing to be largely influenced by social determinants, in conjunction with the implications of the COVID-19 pandemic.

Physical activity, sedentary time and nutritional status in Brazilian children with cerebral palsy

Abstract Objective: This study had the purpose investigate the physical activity (PA) and sedentary time profile of children with cerebral palsy and its association with body composition. Methods: A cross-sectional study evaluated 53 children, between 2 and 10 years old, enrolled in three health services Recife-city, northeast of Brazil. Sedentary and PA were measured for a week using the ActiGraph GTX3 accelerometer. Body composition was assessed by anthropometry and an electrical bioimpedance device. Results: Time on PA was one hour longer among the mild/moderate CP compared to severe ones, but, sedentary time is similar. Dyskinetic children spent more time in PA, but also in sedentary activities (15.5 hours a day) than spastic ones (12.8). Stunting occurred in 15 (30%) of the sample, all children with stunting had severe impairment. Underweight occurred in 25% of the severe group and 11.8% in the mild/moderate group. Overweight affected 3% of the sample; no overweight children were in the severe group. Body fat% was inversely related to time spent in moderate to vigorous PA. Conclusions: Children with CP spend more than a half of their daily time in sedentary activity. In contrast, children with mild to moderate CP spent twice as much time in moderate to vigorous PA and had a tendency (p = 0.07) to spend 50% more time in light PA. Moreover, time spent on moderate to vigorous activity was inversely related to fat mass.

COVID-19 pandemic and physical inactivity in Brazilian university students: a multicenter study / Pandemia de COVID-19 e inatividade física em estudantes universitários brasileiros: um estudo multicêntrico

The aim of this study was to investigate the prevalence of physical inactivity during the COVID-19 pandemic and its association with variables of the pandemic context in Brazilian university students. A cross-sectional, multicentric study was carried out in five public universities in different geographic regions of Brazil. The study included 5,720 students, aged 18 or over, between September 2020 and May 2021. Data collection was performed through a self-administered online questionnaire on the REDCap platform. The dependent variable was physical inactivity. The independent variables were the aspects related to the pandemic. The prevalence of physical inactivity was 48.8% (95%CI: 47.5%; 50.1%), ranging from 26.3% for those who went out every or almost every day for non-essential activities and 64.9 % for those who stayed at home all the time. University students who reported continuing to work normally and who were afraid of the pandemic were more likely to be physically inactive. The groups that were less likely to have the outcome were those with a reduction in income, those who left home more often for essential and non-essential activities, those who started working at home, those who complied with the social distancing, and those who had a risk factor for COV-ID-19. The findings indicate that one in two Brazilian university students are physically inactive and the main risk factors were isolation and fear of the pandemic. Interventions are recommended to promote physical activity, especially for the groups most affected by the COVID-19 pandemic

O objetivo deste estudo foi investigar a prevalência de inatividade física durante a pandemia de COVID-19 e a associação com variáveis do contexto pandêmico em universitários brasileiros. Conduziu-se uma pesquisa transversal, multicêntrica, em cinco universidades públicas das diferentes regiões geográficas do Brasil. Participaram do estudo 5.720 estudantes, de 18 anos ou mais, entre setembro de 2020 e maio de 2021. A coleta de dados foi realizada por meio de um questionário autoaplicável online na plataforma REDCap. A variável dependente foi inatividade física. As variáveis independentes foram os aspectos relacionados à pandemia. A prevalência de inatividade física foi de 48,8% (IC95%: 47,5%; 50,1%), variando entre 26,3% para os que saíram todos ou quase todos os dias para atividades não essenciais e 64,9% para os que ficaram em casa o tempo todo. Universitários que referiram continuar trabalhando normalmente e que tinham medo da pandemia tiveram maior probabilidade de serem inativos fisicamente. Já os grupos que tiveram menor probabilidade para o desfecho foram os que tiveram redução na renda, os que saíram mais de casa para atividades essenciais e não-essenciais, os que passaram a trabalhar em casa, os que cumpriram o distanciamento social e os que tinham algum fator de risco para COVID-19. Os achados indicam que um a cada dois universitários brasileiros são inativos fisicamente e os principais fatores de risco foram continuar trabalhando normalmente e medo da pandemia. Recomendam-se intervenções para promover a atividade física, especialmente para os grupos mais afetados pela pandemia de COVID-19

Participação nas aulas de Educação Física em Pernambuco: uma análise de tendência temporal / Participation in Physical Education classes in Pernambuco: a temporal trend analysis

O objetivo do estudo foi analisar a tendência temporal e fatores associados à participação nas aulas de educação física de estudantes de Pernambuco. Estudo de tendência temporal composto por três levantamentos de abrangência estadual. Foram entrevistados 4.207 estudantes em 2006, 6.264 em 2011 e 6.002 em 2016, por meio do questionário "Global School-based Student Health Survey" (GSHS). O desfecho foi a participação nas aulas de Educação Física e as exposições foram as informações sociodemográficas. A análise bivariada foi realizada mediante teste Qui-quadrado e as análises multivariadas por regressão logística binária. Observou-se um aumento na prevalência de participação nas aulas de Educação Física (2006: 35%, 2011: 74% e 2016: 81,2%) destacando o aumento significativo no sexo masculino Δ% (2006-2016) = 123,5%. Ser do sexo masculino, estudar no período integral e ser filho de mães que estudaram, independente do tempo de estudo foi associado a maior participação nas aulas de educação física, assim como residir nas regiões do Agreste, Sertão e Sertão do São Francisco. Apesar do aumento na participação nas aulas de Educação Física em Pernambuco, a garantia deste componente curricular deve ser fortalecida, levando em consideração os grupos de risco para que aumente a participação nas aulas desses grupos

The aim of the study was to analyze the temporal trend and factors associated with participation in physical education classes in Pernambuco. The temporal trend study was composed of three surveys. A total of 4,207 students were interviewed in 2006, 6,264 in 2011 and 6,002 in 2016, using the "Global School-based Stu-dent Health Survey" (GSHS) questionnaire. The outcome was participation in Physical Education classes and the independent variables were sociodemographic information. The bivariate analysis was performed using the chi-square test and the multivariate analysis using binary logistic regression. There was an increase in the prevalence of participation in Physical Education classes (2006: 35%, 2011: 74% and 2016: 81.2%), highlighting the significant increase in males Δ% (2006-2016) = 123.5%. Male, studying full-time and being the son of mothers who studied was associated with greater participation in physical education classes, as well as living in the regions of Agreste, Sertão and Sertão do São Francisco. Despite the increase in par-ticipation in Physical Education classes in Pernambuco, the guarantee of this curricular component must be strengthened, considering risk groups in order to increase participation in classes for these groups

Movement behaviors in short versus adequate nocturnal sleepers: A compositional analysis of preschoolers.

BACKGROUND: Accruing adequate daily amounts of time spent on movement behaviors (physical activity (PA), sedentary behavior (SB), and sleep) in childhood has been associated with positive short and long-term health outcomes. Nonetheless, how waking time is distributed across PA and SB among preschoolers who are short and adequate sleepers at night is unknown. AIM: This study investigated: (1) if there are differences in a movement behaviors composition among adequate and short nocturnal sleepers; and (2) the association between preschoolers' time spent in PA, SB, and sleep among adequate and short nocturnal sleepers. METHODS: A total of 270 preschoolers (132 boys; 3.97 ± 0.81 years old; 15.48 ± 1.62 kg/m2 ) participated in this study. PA and SB were assessed using accelerometry (model wGT3X). Sleep duration was assessed through a parental-proxy interview, and preschoolers were stratified as short and adequate sleepers, according to attendance to international sleep duration guidelines. Compositional data analysis was used to explore the time-use patterns of behaviors among adequate and short sleepers. RESULTS: Short sleepers spent 64 min less time asleep, accumulated 32 min in more sedentary time (p = .005, Cohen's d = 0.36, Bayes Factor: 6.17), and 24 min more in light PA (p = .0005, Cohen's d = 0.44, Bayes Factor: 46.37) compared to adequate sleepers. CONCLUSIONS: Being a short sleeper was associated with greater time spent in SB and light PA during their waking hours. The health implications of movement behaviors composition among short sleep preschoolers should be further investigated.

Moreover, time spent on moderate to vigorous activity was inversely related to fat mass.

School-Time Movement Behaviors and Fundamental Movement Skills in Preschoolers: An Isotemporal Reallocation Analysis.

Little is known of how reallocations of time spent in different movement behaviors during preschool might relate to preschoolers' fundamental movement skills (FMS), a key predictor of later physical activity (PA). Thus, the aim of this study was to examine (a) whether preschoolers' school-time movement was associated with their FMS and (b) the effects on FMS of reallocating time between PA and sedentary behavior (SB). This was a cross-sectional study, using intervention data with Brazilian low-income preschoolers. We observed Brazilian preschoolers of both sexes (Mage = 4.5, SD = 0.8 years-old; 101boys) over 10 hours of school-time and objectively assessed their PA and SB with Actigraph wGT3X and their FMS with the Test of Gross Motor Development - Second Edition. We explored the associations between school-time movement behaviors and FMS and between reallocated school-time movement behaviors and FES using compositional analysis in R (version 1.40-1), robCompositions (version 0.92-7), and lmtest (version 0.9-35) packages. This isotemporal reallocation showed that, for manipulative skills, reallocating time (5, 10, and 15 minutes, respectively) from light PA to SB was associated with increasing skill (0.14, 0.28, and 0.42 FMS units), raising questions as to whether fine motor activity occurred during SB. Thus, school-time movement significantly predicted FMS, with a modest increase in SB, at the expense of light PA eliciting improved manipulative skills.

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

Atividade física para pessoas com deficiência: Guia de Atividade Física para a População Brasileira / Physical activity for people with disabilities: Physical Activity Guidelines for the Brazilian Population

Visando orientar a população dos benefícios da prática de atividade física à saúde, pesquisadores nacionais, em parceria com o Ministério da Saúde, elaboraram o Guia de Atividade Física para a População Brasileira (Guia). O objetivo deste estudo foi apresentar o processo de elaboração das recomendações brasileiras de atividade física para pessoas com deficiência (PCD). O processo de elaboração das recomendações específicas para PCD foi liderado por um grupo de trabalho com nove pesquisadores/profissionais que realizaram reuniões semanais, e que conduziram revisões sistemáti-cas e escutas com PCD, familiares, gestores, profissionais da saúde, professores e pesquisadores. Na revisão sistemática, um total de 83 estudos foram revisados e incluídos. As escutas foram realizadas por meio de formulários eletrônicos enviados por e-mail para profissionais, gestores, professores e pesquisadores que trabalhavam com PCD e de escutas virtuais, as quais foram conduzidas em dois momentos: (a) com PCD, familiares e profissionais; (b) com professores, gestores; e pesquisadores da temática. Baseado nos resultados das revisões sistemáticas e das escutas, as recomendações de atividade física para PCD foram elaboradas considerando o tempo mínimo de atividade física de acordo com faixas etárias, domínios da atividade física e recomendações para redução do comporta-mento sedentário. Portanto, o presente trabalho apresentou as estratégias e as etapas utilizadas para a elaboração do Guia, com recomendações de atividade física para PCD, as quais podem ser aliadas a políticas públicas, ambientes e oportunidades de atividade física, tornando-se estratégia essencial para o engajamento de PCD em atividades físicas

Aiming to guide the population of the physical activity benefits to health, national researchers, in partnership with the Health Ministry, have elaborated the Physical Activity Guide for the Brazilian population. The aim of this study is to present the process of elaborating Brazilian physical activity recommendations for people with disabilities (PWD). The process of elaborating specific recommendations for PWD has included the participation of nine researchers/professionals who held weekly meetings, systematic reviews, and focus groups with PWD, caregivers, healthcare managers, professionals, and researchers. In the systematic review, a total of 83 studies were included and reviewed. The focus groups were performed using an electronic form sent by e-mail to health professionals, managers, and researchers who worked with PWD and virtual focus groups, which were conducted in two moments: (a) with PWD, caregivers, and professionals; (b) with pro-fessors and researchers on the theme. Based on the results of systematic reviews and focus groups, the physical activity recommendations for PWD were developed considering the minimum physical activity time accord-ing to age group, types of physical activity, and recommendations for reducing sedentary behavior. Therefore, the present work presented recommendations for physical activity for PWD, which can be combined with public policies, environments, and opportunities for physical activity, becoming an essential strategy for the engagement of PWD in physical activities

Combinations of physical activity, sedentary behavior, and sleep and health outcomes in older adults: a systematic review protocol / Combinações de atividade física, comportamento sedentário e sono e desfechos de saúde em idosos: protocolo de revisão sistemática

Recent systematic reviews highlighted important relationships between combinations of movement behaviors (ie. sleep, sedentary behaviour, and physical activity) and health outcomes among children and adolescents. However, it is unclear whether similar relationships occur in older adults. Therefore, the purpose of this protocol was to describe the aims and methods for a systematic review to sum-marize the studies examining the relationships between movement behaviors and health outcomes in older adults.A systematic review will be developed based on searches of articles in seven electronic databases and references of retrieved articles, contact with authors, and study repositories. Eligibility criteria: observational or experimental studies examining the association of at least two movement behaviours (sleep, sedentary behaviour, and physical activity) with health outcomes in older adults (≥ 60 years old). Selection of the studies and extraction of the data will be carried out by two reviewers independently. Characteristics of the study, participants, methods of combinations, and main results will be extracted and described. Risk of bias and level of evidence in the studies will be assessed according to the study quality tool of the US National Heart, Lung, and Blood Institute and the GRADE guidelines. The data will be synthesized using random effects meta-analysis for results that are sufficiently homogeneous in terms of statistical, clinical, and methodological characteristics. If not, then a narrative synthesis will be conducted. The results of this review may provide insights to improve current guidelines on 24-hour cycle in older adults, as well as guide future studies in this research field

Recentes revisões sistemáticas têm demonstrado haver uma relação entre combinações de sono, comportamento sedentário e atividade física e desfechos de saúde em crianças e adolescentes. Entretanto, ainda permanece incerto se essas relações ocorrem de forma similar em idosos. Portanto, este protocolo objetivou descrever os objetivos e métodos de uma revisão sistemática que sumarizará os estudos que examinaram a relação entre combinações de sono, comportamento sedentário e atividade física e desfechos de saúde em idosos. Uma revisão sistemática será desenvolvida com base nas buscas de artigos em sete bases de dados, nas referências dos artigos incluídos, em contato com os autores e em repositório de estudos. Como critérios de inclusão, estudos observacionais ou experimentais analisando a associação entre a combinação de pelo menos dois dos três comportamentos (sono, comportamento sedentário e atividade física) com desfechos de saúde em idosos (≥ 60 anos). O processo de seleção e extração dos dados será realizado por dois revisores de forma independente. As características dos estudos, participantes, métodos de combinação dos comportamentos e principais resultados serão extraídos e descritos. O risco de viés e o nível de evidência serão analisados, respectivamente, pela ferramenta de avaliação de qualidade do US National Heart, Lung, and Blood Institute e pelo guideline GRADE. Os dados serão sintetizados usando metanálise com efeitos randômicos quando os resultados apresentaram suficiente homogeneidade estatística, clínica e metodológica. Do contrário, os resultados serão apresentados por meio de síntese narrativa. Os resultados desta revisão podem fornecer informações para aprimorar as diretrizes do ciclo das 24 horas, bem como podem fornecer informações para futuros estudos nesse campo de pesquisa

Psychosocial aspects of physical activity: data on brazilian adolescents / Aspectos psicossociais da atividade física: dados sobre adolescentes brasileiros / Aspectos psicosociales de la actividad física: datos sobre adolescentes brasileños

ABSTRACT Introduction Although the benefits of regular physical activity (PA) for adolescents are well-described in the literature, there is little evidence of the role of psychosocial aspects on levels of PA in this population. Objective To investigate the prevalence and sociodemographic factors associated with enjoyment of PA and preference for leisure-time activities in boys and girls. Methods A cross-sectional study, with 6529 adolescents (aged 15 to 19 years) enrolled in secondary education in public schools in the South of Brazil. Logistic regression was used to analyze the association between sociodemographic factors and the variables of interest, with data collection using a standardized questionnaire. Results Boys enjoyed (87.1%) and preferred (44.4%) PA more than girls (enjoyment: 79.2%; preference: 29.5%). Among the boys, enjoyment was associated with family income(OR3-5 wages=1.53; OR≥6 wages=1.62) and, among the girls, it was associated with age (OR19 years=0.28), occupational status (ORworkers=1.45), and income (OR3-5 wages=1.35). Preference was associated with age (OR19 years=2.48) and income (OR≥6 wages=0.70) among the boys and, among girls, it was associated with area of residence (ORrural=1.47) and occupation (ORworkers=1.31). Conclusion Boys (enjoyment: 87.1%; preference: 44.4%) had more positive attitudes toward PA than girls (enjoyment: 79.2%; preference: 29.5%), and some sociodemographic variables appear to be more closely associated with these attitudes than others. Enjoyment was associated with family income for boys, and with age, occupation and income for girls. Preference, in turn, was associated with age and family income for boys, and area of residence and occupational status for girls.

RESUMO Introdução Embora os benefícios da atividade física (AF) regular para os adolescentes sejam consolidados na literatura, há pouca evidência do papel dos aspectos psicossociais nos níveis de AF nessa população. Objetivo Investigar a prevalência e os fatores sociodemográficos associados ao gosto pela AF e à preferência por atividades no lazer em rapazes e moças. Métodos Estudo transversal, com 6.529 adolescentes (15 a 19 anos), matriculados no ensino médio das escolas públicas do sul do Brasil. Usou-se regressão logística binária para analisar a associação entre os fatores sociodemográficos e as variáveis de interesse, coletadas por meio de questionário padronizado. Resultados Os rapazes relataram gostar (87,1%) e preferir (44,4%) AF mais do que as moças (gostar: 79,2%; preferir: 29,5%). Entre os rapazes, o gosto pela AF foi associado à renda familiar (OR3-5 salários = 1,53; OR≥6 salários = 1,62) e, entre as moças, foi associado à idade (OR19 anos = 0,28), ocupação (ORtrabalhadoras = 1,45) e renda (OR3-5 salários = 1,35). A preferência foi associada à idade (OR19 anos = 2,48) e à renda familiar (OR≥6 salários = 0,70) para os rapazes, e, para as moças, à área de residência (ORrural = 1,47) e ocupação (ORtrabalhadoras = 1,31). Conclusões Rapazes (gostar: 87,1%; preferir: 44,4%) tiveram atitudes mais positivas com relação à AF do que as moças (gostar: 79,2% e preferir: 29,5%), e algumas variáveis sociodemográficas parecem estar mais fortemente associadas a essas atitudes do que a outras. Gostar foi associado à renda familiar para os rapazes e à idade, ocupação e renda para as moças. Preferir, por sua vez, esteve associado à idade e à renda familiar para os rapazes e à área de residência e ocupação para as moças.

RESUMEN Introducción Aunque los beneficios de la actividad física (AF) regular para los adolescentes sean consolidados en la literatura, hay poca evidencia del papel de los aspectos psicosociales en los niveles de AF en esa población. Objetivo Investigar la prevalencia y los factores sociodemográficos asociados al gusto por la AF y a la preferencia por actividades en la recreación en adolescentes de ambos sexos. Métodos Estudio transversal, con 6.529 adolescentes (15-19 años), matriculados en la enseñanza media de las escuelas públicas del sur de Brasil. Se usó regresión logística binaria para analizar la asociación entre los factores sociodemográficos y las variables de interés, colectadas por medio de cuestionario estandarizado. Resultados Los adolescentes de sexo masculino relataron gusto (87,1%) y preferencia (44,4%) por AF más que las adolescentes de sexo femenino (gusto: 79,2%; preferencia: 29,5%). Entre los varones, el gusto por la AF fue asociado a la renta familiar (OR3-5 salarios= 1,53; OR≥6 salarios= 1,62) y, entre las adolescentes de sexo femenino, fue asociado a la edad (OR19 años= 0,28), ocupación (ORtrabajadoras= 1,45) y renta (OR3-5 salarios= 1,35). La preferencia fue asociada a la edad (OR19 años= 2,48) y a la renta familiar (OR≥6 salarios= 0,70) para los varones y, para las adolescentes de sexo femenino, al área de residencia (ORrural= 1,47) y ocupación (ORtrabajadoras= 1,31). Conclusiones Los adolescentes de sexo masculino (gusto: 87,1%; preferencia: 44,4%) tuvieron actitudes más positivas con relación a la AF que las adolescentes de sexo femenino (gusto: 79,2%; preferencia: 29,5%), y algunas variables sociodemográficas parecen estar más fuertemente asociadas a esas actitudes que a otras. El gusto fue asociado a la renta familiar para los varones y a la edad, ocupación y renta para las adolescentes de sexo femenino. La preferencia, a su vez, estuvo asociada a la edad y a la renta familiar para los varones, y el área de residencia y ocupación para las adolescentes de sexo femenino.

Adherence to 24-hour movement guidelines in low-income Brazilian preschoolers and associations with demographic correlates.

BACKGROUND: The importance of movement behaviors for health is well known, although few studies have examined the adherence to movement guidelines in low-income preschoolers from a middle-income country, as Brazil. This study reports the proportion of preschoolers meeting the 24-hour movement guidelines and investigates its associations with demographic correlates in Brazilian low-income preschoolers. METHODS: Two hundred and seventy preschoolers (132 boys, means age = 3.97 ± 0.80) provided physical activity (PA) data (Actigraph wGT3X). Sleep duration, screen time, and social correlates were parent-reported. Preschoolers were classified as compliant/not compliant with the 24-hour movement guidelines. Relationships between compliance with movement behaviors guidelines and demographic correlates were calculated using a network analysis (Mplus 8.0; Rstudio). RESULTS: Preschoolers were active (273.52 ± 62.08 minutes/day of total PA), though moderate-to-vigorous physical activity (MVPA) time was below the guideline (58.68 ± 22.51 minutes/day); spent more than the recommended 60 minutes/day on screen time (169.91 ± 97.07 minutes/day); and slept less than 10 hours per night (9.44 ± 1.12 hours/day). Only 3% of the sample complied with the guidelines. PA showed the highest compliance (43%), compared to sleep duration (35%) and screen time (15%). Male sex was related to adherence to MVPA recommendations, while female sex, with adherence to total PA recommendations. Child's primary caregiver was the most important centrality indicator in the network. CONCLUSION: Only 3% of the assessed preschoolers are compliant with the 24-hour movement behaviors guidelines. Strategies to promote adherence to movement behaviors among low-income preschoolers should consider child's primary caregivers to support movement behaviors.

Validation of Questionnaire on Violence in Affective Relationships.

The aim was to describe the criteria for construction, validation of content, and appearance of a questionnaire for the identification of violence in affective relationships in adolescence. Transverse methodological study, with a quantitative approach, conducted in the period between June and November 2017, with the construction of a questionnaire and validation of the content and appearance, by means of a Delphi survey with 20 experts on the area of violence and adolescence. To evaluate the clarity and pertinence of the items of the questionnaire, a pilot test was conducted with 76 adolescents, and analysis of the validity of content and reliability of the items by means of Content Validity Index (CVI), the Interrater Agreement (IRA), and the Cronbach alpha. The data were analyzed and processed by means of the Excel and Stata, version 14.0, programs. The indexes calculated in the first round of Delphi provided the following results: CVI = 0.93 and IRA = 0.93, showing evidence of the validity and reliability of the construct content, and in the second round, the questionnaire yielded a percentage of 100% agreement among the professionals and researchers. Verification of the internal consistency presented a mean value of 0.803, calculated by means of the Cronbach alpha. The questionnaire has validity of content and appearance in accordance with the proposed objective, bearing in mind that the indexes of faithfulness and agreement and the Cronbach alpha attained values above those of the established pattern of 80%.
