RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVES: The aim of the study is to assess STRONGkids as a tool for predicting weight loss and length of hospital stay in children and to determine whether the anthropometric diagnosis of nutritional status at the time of admission was associated with weight loss and length of hospital stay. METHODS: A methodological study recruiting 245 children age between 1 and 10 years of age admitted to a tertiary hospital. The participants were weighed daily until discharge. Validation of the STRONGkids tool for the identification of patients sustaining weight loss at the end of hospitalization involved the calculation of sensitivity, specificity, and positive and negative predictive values, and anthropometric assessment. RESULTS: A total of 129 (52.7%) children lost weight at the end of hospitalization. Of these, 73 (56.6%) lost over 2% of their weight on admission. The tool had a sensitivity of 55.8%, a specificity of 38.8% and a positive predictive value of 50.3% in identifying children who lost weight. The anthropometric assessment had a sensitivity of 26.5%, a specificity of 75.9%, and a positive predictive value of 49.1%. CONCLUSIONS: The model used to develop the STRONGkids tool incorporated clinical evaluation to a greater extent than the assessment of nutritional status. The tool, however, had a low sensitivity and a high percentage of false positives. Therefore, it should be considered as a preliminary evaluation tool and its use should be complemented with clinical data.

RESUMEN

This study evaluated the effect of a multi-component intervention on motor performance (MP) and metabolic risk markers (MRM) in overweight/obese youth. A secondary aim was to examine whether changes in MP are associated to changes in MRM. A 3-month multi-component intervention was performed, consisting of physical exercise sessions (twice/week;1h), nutritional education sessions (once/month), and parental support (twice/week). The sample included 35 volunteers (7-13 y.o), allocated to intervention (INT, n = 17) and control (CONT, n = 18) group. Variables were measured pre (T0) and post intervention (T1). Fasting blood samples were analyzed for MRM. MP tests included the measurement of health related physical fitness components and motor coordination performance (KTK battery). To assess food intake, a 24-hour recall diary was used. GLM-ANCOVA was performed. Standardized scores were calculated for the outcome variables, and multilinear regressions were applied to analyze associations between the key variables. INT group showed improvements in MP, glycolytic and hepatic profiles. After adjustments for MVPA, SB, total intake and maturational stage, negative associations between %ΔMP and %Δglycolytic (ß = -.424; 95%CI:-0.343:-0.022), and %Δhepatic scores (ß = -.382 95%CI:-0.001:-0.009) were observed. The intervention produced a moderate-to-high effect on the MP and some MRM. Changes in MP were inversely associated with changes in glycolytic and hepatic markers.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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%.

RESUMEN

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.

RESUMEN

In Brazil, physical activity is a priority area in health promotion in the Brazilian Unified National Health System (SUS). The study aims to describe users' profiles and the barriers and facilitators in basic healthcare for participation in programs to promote physical activity. This was a statewide cross-sectional study in municipalities (counties) in Pernambuco State. Between 2 and 21 individuals were interviewed per municipality, using a previous tested instrument, validated in the following dimensions: sociodemographic; health status; participation; information on the program; reasons for participation; facilitators; barriers; and preference of activities. Descriptive and inferential analyses (chi-square) were performed. The sample consisted of 1,153 users, 35.9% of whom between 41-59 years of age; 90.1% lived in urban areas; 58.2% had participated in physical activities for at least a year. Weekly frequency of 3-4 days was 44.9%, and 71.1% practiced activities of an hour or more. The results showed that 40% of the barriers to participation in physical activity programs and 77.5% of the facilitators belonged to the intrapersonal domain. The most prevalent barrier was "current health condition" and the facilitator was the desire "to be healthier". Women perceived more barriers than men. The conclusion is that barriers and facilitators from the intrapersonal domain, related to health, are the main factors involved in users' engagement and retention in programs and interventions to promote physical activity, developed in basic healthcare services in the state of Pernambuco.


No Brasil, a atividade física é eixo prioritário das ações de promoção da saúde no Sistema Único de Saúde (SUS). O presente estudo tem como objetivo descrever o perfil dos usuários, as barreiras e os facilitadores para participação em programas para promoção de atividades físicas na atenção básica à saúde. Trata-se de um estudo transversal com abrangência estadual realizado nos municípios de Pernambuco. Foram entrevistados de 2 a 21 indivíduos, por município, por meio de instrumento previamente testado e validado nas dimensões: sociodemográfica; estado de saúde; participação; informações sobre o programa; motivos de participação; facilitadores para a prática; barreiras para a prática e preferência de atividades. Foram realizadas análises descritivas e inferenciais (qui-quadrado). A amostra foi de 1.153 usuários, sendo 35,9% com idade entre 41-59 anos; 90,1% residentes em áreas urbanas; 58,2% dos usuários participavam das atividades há, pelo menos, um ano. A frequência semanal de 3-4 dias foi de 44,9%, e 71,1% praticavam atividades de uma hora ou mais. Observou-se que 40% das barreiras para a participação nos programas de atividade física e 77,5% dos facilitadores relatados foram de domínio intrapessoal. A barreira mais prevalente foi "condição atual de saúde", e o facilitador foi "ter uma condição melhor de saúde". As mulheres percebem mais barreiras do que os homens. Conclui-se que as barreiras e os facilitadores de domínio intrapessoal, relacionados com a saúde, são os fatores envolvidos na manutenção e no engajamento dos usuários dos programas e intervenções para promoção da atividade física desenvolvidos pela atenção básica à saúde do Estado de Pernambuco.

RESUMEN

Restricted sodium intake has been recommended for more than 1 century for the treatment of hypertension. However, restriction seems to increase blood cholesterol. In women with excess weight, blood cholesterol may increase even more because of insulin resistance and the high lipolytic activity of adipose tissue.The aim of this study was to assess the association between blood cholesterol and sodium intake in hypertensive women with and without excess weight.This was a cross-sectional study with hypertensive and nondiabetic women aged 20 to 59 years, recruited at the primary healthcare units of Maceio, Alagoas, Brazilian Northeast. Excess weight was defined as body mass index (BMI) ≥25.0 kg/m. Sodium intake was estimated by the 24-hour urinary excretion of sodium. Blood cholesterol was the primary outcome investigated by this study, and its relationship with sodium intake and other variables was assessed by Pearson correlation and multivariate linear regression using a significance level of 5%.This study included 165 hypertensive women. Of these, 135 (81.8%) were with excess weight. The mean sodium intake was 3.7 g (±1.9) and 3.4 g (±2.4) in hypertensive women with and without excess weight, respectively. The multiple normal linear regression models fitted to the "blood cholesterol" in the 2 groups reveal that for the group of hypertensive women without excess weight only 1 independent variable "age" is statistically significant to explain the variability of the blood cholesterol levels. However, for the group of hypertensive women with excess weight, 2 independent variables, age and sodium intake, can statistically explain variations of the blood cholesterol levels.Blood cholesterol is statistically inversely related to sodium intake for hypertensive women with excess weight, but it is not statistically related to sodium intake for hypertensive women without excess weight.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Abstract 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.

RESUMEN

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

RESUMEN

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

RESUMEN

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.

RESUMEN

The aim of this study was to analyze the influence of the number of visits and the number of blood pressure (BP) measurements on the prevalence of high blood pressure (HBP) in adolescents. A cross-sectional epidemiologic study with 481 adolescents (14-19 years old) selected using a random cluster sampling strategy. We measured the BP three times in a first visit. Adolescents with HBP performed subsequent visits. The final calculation of BP followed four strategies: the 1st measure, mean of 1st and 2nd measurements, mean of all three measurements, and averaging the 2nd and 3rd measurements. The prevalence of HBP in the first and second visits was 6.4% and 1.9%, and the prevalence of hypertension (after three visits) was 1.7%. The prevalence of HBP varied from 8.6%-18.6% for boys and 4.6%-9.2% for girls, using the average 2nd and 3rd measurements and the 1st measurement, respectively. In all strategies, HBP and hypertension were more prevalent in boys and students attending the nocturnal shift. The number of visits and number of measurements affect the prevalence of HBP and hypertension in adolescents. Thus, clinicians and researchers should consider these aspects when assessing BP in adolescents aged 14-19 years old.
