RESUMO
OBJECTIVE: The aim of the study was to analyze gender inequalities in types of physical activity (PA) and in the use of screen-based devices among schoolchildren from both urban and rural areas in Brazil. METHODS: Data from two population-based surveys conducted in 2019 (urban areas: n = 2,479; 52.6% girls; age = 9.2 ± 1.51 years) and 2022 (rural areas: n = 979; 42.6% girls; age = 9.4 ± 1.52 years) were used. PA (active play, nonactive play, home chores, and structured physical activities) and the use of screen-based devices (TV, cellphone, videogame, and computer) were self-reported in a previous-day-recall online questionnaire (Web-CAAFE). Absolute gender inequalities were evaluated and presented as equiplots. Relative gender inequalities were evaluated by the prevalence ratio (PR) and respective 95% confidence intervals (95% CI), which were estimated by Poisson regression, with adjustments for age and BMI z scores. RESULTS: Girls from urban and rural areas presented a lower prevalence of active play and a higher prevalence of home chores. The prevalence of nonactive play among girls from urban areas was also lower; however, their prevalence of structured physical activities was higher, especially among girls aged seven to nine years. Girls in both urban and rural areas presented a higher prevalence of TV viewing and lower use of video games. CONCLUSION: The gender inequalities observed in the types of physical activities and in the use of screen-based devices could be considered potential correlates of the likelihood of girls' and boys' compliance with the physical activity guidelines.

BACKGROUND: Attendance in physical education classes (PE) helps young people to achieve the physical activity recommendations and to reduce their exposure to sedentary behavior. However, the association between PE attendance and the daily frequency of specific forms of physical activity is less known. The current study analyzed the association between weekly attendance in PE and daily frequencies of different forms of physical activity (active play, non-active play, structured physical activity), and overall daily frequencies of physical activity (PA) and sedentary behaviors (SB) among schoolchildren. METHODS: Cross-sectional study with schoolchildren from second to fifth grade of 11 public schools (n = 2,477; 9.1 ± 1.38-y-old; 53.2% girls; 17.5 ± 3.5 kg/m2) in Feira de Santana (Northeast Brazil). PA, SB, and attendance in PE were self-reported using a previously validated on-line questionnaire based on the previous day's recall (Web-CAAFE). Multiple Binomial Negative regression modeling was carried out to analyze the association (Prevalence Rate: PR) between weekly attendance in PE (0/week, 1/week, ≥ 2/week) and frequencies of active play, non-active play, and structured physical activity, with adjustments by age, school shift, and BMI z-scores. Regression models analyzing overall PA also included adjustments by household chores. RESULTS: Attendance in PE ≥ 2/week was associated with higher frequencies of active play (girls: PR = 1.40, 95%CI = 1.11-1.78; boys: PR = 1.49, 95%CI = 1.15-1.94) and structured physical activity (girls: PR = 2.11, 95%CI = 1.31-3.40; boys: PR = 4.33, 95%CI = 1.63-11.52). Higher attendance in PE (≥ 2/week) was associated with high overall PA (girls: PR = 1.31, 95%CI = 1.06-1.62; boys: PR = 1.42, 95%CI = 1.14-1.77) and low SB (girls: PR = 0.80, 95%CI = 0.71-0.90; boys: PR = 0.81, 95%CI = 0.68-0.97). Attendance in PE 1/week was also associated with a lower frequency of daily SB among girls (PR = 0.73, 95%IC = 0.64-0.84) CONCLUSION: Higher weekly attendance in PE was associated with higher frequencies of active play, structured physical activity, higher overall PA, and lower SB among both girls and boys.

BACKGROUND: The intake of unhealthy food taken on very regular basis may bring even further negative impact on health if associated with excessive time using of screen-based electronic devices. OBJECTIVE: To estimate the association between the use of different types of screen-based devices and the intake of unhealthy foods amongst children and adolescents and to determine whether daily physical activity (DPA) has a moderating effect on the association. METHODS: Cross-sectional study carried out with a probabilistic sample of students from second to fifth grade of public elementary schools in Feira de Santana, Bahia (n = 2,477; girls: 53.2%; age: 9.1 ± 1.38 years; BMI z-score 0.37 ± 4.19 Kg/m²). Food intake, screen use, and physical activity were assessed using an online questionnaire based on previous day recall (Web-CAAFE). Prevalence Ratios (PR) and 95% Confidence Intervals (95%CI) were estimated via multiple zero-inflated negative binomial regression, with adjustments for sex, age, and weekly frequency of school meal intake. The moderating effect of DPA was verified by inserting interaction terms with each screen-based device individually and with the daily sum of screen-based device exposure (∑ Screens). RESULTS: The majority of students (72.2%) reported using screens. The intake of unhealthy foods was positively associated with the use of cell phones (PR = 1.21; 95%CI = 1.13-1.30), computers (PR = 1.33; 95%CI = 1.22-1.46), and video games (PR = 1.36; 95%CI = 1.22-1.52). TV use was inversely associated with intake of unhealthy foods (PR = 0.92; 95%CI = 0.87-0.99). DPA moderated the effect of video game use on intake of unhealthy foods, that is, among students with DPA ≥ 4 who used video games, the intake of unhealthy foods was 21% lower (PR = 0.79; 95%CI = 0. 65-0.97). Overall, ∑ Screen-based devices were associated with a 20% increase in intake of unhealthy foods. CONCLUSION: The intake of unhealthy foods was positively associated with the use of cell phones, computers, and video games. In addition, a frequency of four or more DPA attenuated the effect of video game exposure on intake of unhealthy foods. Upcoming investigations on the use of screen-based devices and the intake of unhealthy foods among schoolchildren should consider the exposure to different types of screen-based devices, as well as the influence of DPA.
RESUMO
O objetivo deste estudo transversal foi analisar a associação entre ambiente construído no bairro e na escola e atividade física diária (AFD) e uso de telas diário (TD) entre estudantes de diferentes padrões de comportamentos. Participaram estudantes (9,1 ± 1,38 anos, 53,2% meninas) do 2º ao 5º ano de escolas públicas (n = 2.384) da cidade de Feira de Santana, BA. Atividades físicas e comporta-mentos sedentários foram avaliadas através de questionário online (Web-CAAFE) e utilizadas para definir os padrões de comportamentos por análise de cluster, segmentada por sexo. Ambiente cons-truído na escola (parquinho e espaços cobertos para atividades físicas) e no bairro (quadras esportivas, campos de futebol, parques e praças) foram as exposições. Os desfechos, AFD e TD, foram obtidos pelos somatórios dos relatos de um dia. Modelos de regressão binomial negativa, controlados por idade e escore-z de Índice de Massa Corporal, estimaram razões de prevalência (RP) e intervalos de confiança de 95% (IC95%). A AFD associou-se a praças entre meninas "jogadoras ativas" (RP = 1,35; IC95%: 1,09 - 1,68) e a Espaços cobertos para atividades físicas entre "sedentárias/executoras de tarefas domésticas" (RP = 0,86; IC95%: 075 - 0,97). Entre meninos "sedentários em atividades acadêmicas" a AFD associou-se a Campos de futebol (RP = 1,20; IC95%: 1,02 - 1,42) e TD a Parquinho (RP = 1,17; IC95%: 1,00 - 1,37). TD também foi associado a Espaços cobertos para atividade física entre "sedentários em telas" (RP = 1,28; IC95%: 1,04 - 1,57). AFD e TD de meninos e meninas com diferentes padrões de comportamento foram associados a diversos fatores do ambiente construído
The aim of this cross-sectional study was to analyze the association between the built environment at school and in the neighborhood and daily physical activity (DPA) and daily screen use (DS) among students with different behavioral patterns. Participants were students (9.1 ± 1.38 years, 53.2% girls) from the 2nd to the 5th year of public schools (n = 2,384), in the city of Feira de Santana, BA. Physical activities and sed-entary behaviors were assessed using an online questionnaire ( Web-CAAFE) and used to define behavioral patterns by cluster analysis, segmented by gender. Built environment at school (playground and covered spaces for physical activities) and in the neighborhood (sports courts, soccer fields, parks and squares) were the exposures variables. The outcomes, DPA and DS, were obtained by the sum the one-day reports. Mul-tiple negative binomial regression models, controlled for age and Body Mass Index z-score, were estimated prevalence ratios (PR) and 95% confidence intervals (95%CI). DPA was associated with squares among "active players" girls (PR = 1.35; 95%CI: 1.09 - 1.68) and with covered spaces for physical activities among "sedentary/Household chores performers" (PR = 0.86; 95%CI: 075 - 0.97). Among "sedentary in academic tasks" boys, DPA was associated with Soccer fields (PR = 1.20; 95%CI: 1.02 - 1.42) and DS with Play-ground (PR = 1.17; 95%CI: 1.00 - 1.37). DS was also associated with Covered spaces for physical activity among "sedentary on screen" (PR = 1.28; 95%CI: 1.04 - 1.57). DPA and DS of boys and girls with different behavior patterns were associated with several built environment factors

RESUMO O objetivo deste estudo ecológico foi estimar desigualdades nas instalações para atividades físicas e esportes (AF) nas escolas públicas de Educação Básica brasileiras (n=70.276), conforme a proporção de matrículas de estudantes autodeclarados negros. Os resultados mostraram que escolas urbanas e rurais com maior proporção de matrículas de estudantes negros (≥60%) apresentaram menos pátio descoberto, quadra coberta e descoberta, parque infantil, estúdio de dança e materiais para a prática desportiva e recreação. Essas desigualdades são traços do racismo, que é estruturante na sociedade brasileira e é institucionalizado na oferta de condições desfavoráveis ao engajamento em AF nas escolas públicas que atendem um maior número de alunos pretos e pardos.
ABSTRACT The aim of this study was to estimate inequality in physical activity and sports facilities at Brazilian public elementary schools, according to percent of self-reported black students. Our results showed that schools from urban or rural areas with a higher percentage of enrollments of self-reported black students (≥60%) presented fewer outdoor courtyards, sport court indoor and outdoor, playgrounds, dance studios, and materials for sports and recreation. These inequalities are a feature of racism, which is structural in Brazilian society and institutionalized in unfavorable conditions for engaging in physical activity and sports at public elementary schools where there is a higher number of black students.
RESUMEN Este estudio ecológico tuvo como objetivo estimar las desigualdades en las instalaciones para actividades físicas y deportivas (AF) en las escuelas públicas brasileñas de Educación Básica (n=70.276), según la proporción de matrículas de alumnos que se declararon negros. Los resultados mostraron que las escuelas urbanas y rurales con mayor proporción de matrículas de estudiantes negros (≥60%) tenían menos patio al aire libre, canchas interiores y exteriores, parques infantiles, estudios de danza y materiales para deportes y recreación. Esas desigualdades son rasgos del racismo, que es estructural en la sociedad brasileña y está institucionalizado al ofrecer condiciones desfavorables para la práctica de AF en las escuelas públicas que atienden a un mayor número de alumnos negros y pardos.
RESUMO
O estudo descreveu as alterações comportamentais durante a pandemia de COVID-19 e sua asso-ciação com o sobrepeso e obesidade atual de crianças e adolescentes. Participaram do estudo 1.004 crianças e adolescentes de comunidades rurais em áreas de remanescentes de quilombos de Feira de Santana, Bahia (50,3% meninos; Idade: 9,04 ± 1,52 anos). Desfechos: sobrepeso e obesidade, com base nos valores de Índice de Massa Corporal para idade e sexo, avaliados nos pontos de corte da In-ternational Obesity Taskforce. Alterações comportamentais (apetite, sono, psicológicas, sociais) foram avaliadas por meio de questionário preenchido pelos pais. A análise de dados incluiu estatística des-critiva, bivariada e regressão de Poisson múltipla, com estimador robusto de variância, para estimar Razões de Prevalência (RP) e Intervalos de 95% de Confiança (IC95%). A significância estatística foi fixada em valores de p<0,05. Covariáveis: idade, sexo, infecção por COVID-19 e insegurança ali-mentar. Após o período pandêmico, 24% dos participantes estavam com excesso de peso (sobrepeso = 15,5%; obesidade: 8,5%). As principais alterações comportamentais ocorreram no apetite (comer muito mais do que o habitual = 45,6%) e no sono (ir dormir e acordar mais tarde do que o habitual, em 74% e 62,2%, respectivamente). Comer mais que o habitual foi fator associado ao sobrepeso (RP = 1,63; IC95%: 1,14 - 2,32) e à obesidade (RP = 2,00; IC95%:1,22 - 2,25) entre os participantes, após ajuste por sexo, idade, infecção por COVID-19 e insegurança alimentar. As prevalências de sobrepe-so e obesidade subsequentes ao período pandêmico se associaram às alterações comportamentais no apetite ocorridas durante a pandemia entre escolares Quilombolas
The aim of the study was to describe behaviors changes during COVID-19 pandemic and its association with subsequent overweight and obesity among Quilombola schoolchildren. Participants in this study were 1,004 children and adolescents from rural communities in the Quilombo areas of Feira de Santana, Bahia (50.3% boys; Age: 9.04 ± 1.52 years). The outcomes were overweight and obesity prevalence based on age-and-sex Body Mass Index values, evaluated according to the International Obesity Task Force cut-offs. Behavior changes (appetite, sleep, psychological, and social) were measured by a proxy report questionnaire. The analysis included descriptive statistics and multiple Poisson regression models, using robust variance to estimate Prevalence Ratio (PR) and 95% Confidence Intervals (95%CI). Co-variables: age, sex, COV-ID-19 infection, and food insecurity. The results presented 24% of overweight subsequent to the pandemic period (overweight without obesity = 15.5%; obesity = 8.5%). Main behavior changes occurred in diet (eating more than usual = 45.6%) and sleep (time to go to bed/time to wake up later than usual, among 74% and 62.2% of participants, respectively). Eating mor than usual was associated to overweight without obesity (PR = 1.63; 95%CI: 1.14 - 2.32) and obesity (PR = 2.00; 95%CI: 1.22 - 2.25), when adjusted by sex, age, COVID-19 infection, and food insecurity. Being overweight and obese subsequent to the COV-ID-19 pandemic was associated with behavior changes in the appetite during the pandemic period among Quilombola schoolchildren

We analyzed the association between school attendance and the daily frequency of use of different forms of screens (TV, computer, cell phone and video game) among children and adolescents. Lon-gitudinal study with four repeated measures during the 2015 school year. Children and adolescents from a public school participated in the study (n = 463, 53.6% boys; 9.3 ± 1.3 years old). The daily frequency of screen use was the outcome analyzed, which was reported on an online questionnaire for the previous-day recall, illustrated with 32 icons of activities including 4 types of electronic de-vices. The participant answered "What did you do yesterday?" in the morning, afternoon, and night. School attendance was assessed by responding to the item "Did you go to school yesterday?". The analysis was conducted using generalized estimation equations, with adjustment by sex, age, BMI z-scores, and season of the year. The average percentage of absences during the follow-up was 28.7%. The use of screens was 13% higher among students who missed class. Playing a video game was 37% higher among students who missed class. The daily frequency of screen use was 26% higher among adolescents (10-12 years) compared to children (7-9 years), especially in the analysis performed indi-vidually for TV and cell phone. The daily frequency of screen use and watching TV among students who missed classes during the winter was, respectively, 24% (IRR = 1.24; 95%CI = 1.11 - 1.39) and 35% (IRR = 1.35; 95%CI = 1.10 - 1.66) higher compared to those who missed classes during the fall. In conclusion, the use of screens predominated among students who missed class, mainly in winter
Nós analisamos a associação longitudinal entre presença na escola e frequência diária de uso de diferentes tipos de telas (TV, celular, computador e videogame). O follow-up incluiu quatro medidas repetidas durante o ano letivo de 2015. Participaram do estudo crianças e adolescentes de escola pública (n = 463; 53,6% meninos; 9,3 ± 1,3 anos). O uso de telas foi o desfecho analisado, relatado em um questionário online para a recordação do dia anterior, ilustrado com 32 ícones de atividades, incluindo 4 tipos de dispositivos eletrônicos. O participante respondeu "O que você fez ontem?" pela manhã, tarde e noite. A frequência escolar foi avaliada por meio do item "Você veio à escola ontem?". A análise foi conduzida via equações de estimativa generalizada, com ajuste por sexo, idade, estação do ano e escore-z de IMC. O percentual médio de faltas no período foi de 28,7%. De maneira geral, o uso de telas foi 13% mais frequente entre estudantes que faltaram à aula, com destaque para vídeogame, cuja frequência diária foi 37% maior. Adolescentes (10-12 anos) exibiram frequência diária de telas 26% maior quando comparados com as crianças (7-9 anos), especialmente de TV (36%) e celular (32%). A frequência diária de uso de telas e de assistir TV entre os alunos que faltaram às aulas no inverno foi, respectivamente, 24% (IRR = 1,24; IC95% = 1,11 - 1,39) e 35% (IRR = 1,35; IC95% = 1,10 - 1,66) maior em relação aos que faltaram às aulas no outono. Concluímos que o uso de telas predominou entre estudantes que faltaram à aula, sobretudo no período do inverno

Este estudo analisou a variação sazonal das atividades físicas e dos comportamentos sedentários de uma amostra por conveniência de crianças e adolescentes, de uma escola pública no semiárido baiano (n = 462; 52,9% de meninos; 7-12 anos). Trata-se de um estudo longitudinal de um ano de seguimento. Atividades físicas e comportamentos sedentários foram relatados no questionário Consumo Alimentar e Atividade Física de Escolares (Web-CAAFE). As medidas repetidas foram realizadas no outono, inverno e primavera. Os desfechos avaliados foram: quantidade de atividades físicas diária (AFD) e de comportamentos sedentários (CS), frequências de atividades físicas leves (AFL), moderadas (AFM) e vigorosas (AFV ). Análises foram conduzidas via modelagem de equações de estimativa generalizada (GEE) (distribuição Poisson), com ajuste por temperatura ambiente e precipitação pluviométrica. Não houve variação sazonal estatisticamente significativa na AFD. No inverno, houve mais relatos de AFL (Coef² = 1,37; IC95%: 1,14-1,66) e de CS (Coef² = 1,16; IC95%: 1,05-1,29), enquanto AFV foram menos frequentes (Coef² = 0,83; IC95%: 0,71-0,97). AFV foram menos relatadas no outono (Coef² = 0,82; IC95%: 0,69-0,98). Sexo modificou o efeito das estações nas AFV, que entre meninos, ocorreram mais no outono (Coef² = 1,72 IC95%=1,16-2,56) e no inverno (Coef² = 1,84; IC95%: 1,26-2,69). Idade modificou efeito das estações sobre os CS. Durante o seguimento, houve mais CS na faixa etária 10-12 anos, porém, com diferença estatística significativa no outono e no início da primavera. O inverno favoreceu as AFL e os CS, mas restringiu as AFV, sobretudo entre meninas. Estudantes de 10-12 anos apresentaram mais CS, especialmente no outono e início da primavera
This one-year follow-up study analyzed the seasonal variation of physical activities and sedentary behaviors among children and adolescents, from public schools in the semiarid region of Bahia state (convenience sample, n = 462; 52.9% boys; 7-12 years). Physical activities and sedentary behaviors were reported in the Food Intake and Physical Activity of School Children Questionnaire ( WEB-CAAFE). Seasonal measure-ments were performed in fall, winter and spring. The outcomes were: daily amount of physical activities (DPA) and sedentary behaviors (SB), frequencies of light (LPA), moderate (MPA) and vigorous ( VPA) physical activities. The analyses were conducted via modeling of generalized estimation equations (GEE), with adjustment by temperature and rainfall. There was no statistically significant seasonal variation in DPA. During winter, there were more reports of LPA (Coef² = 1.37; 95%CI: 1.14-1.66) and SB (Coef² = 1.16; 95%CI: 1.05-1.29), while VPA was less frequent (Coef² = 0.83; 95%CI: 0.71-0.97). VPA occurred less in the fall (Coef² = 0.82; 95%CI: 0.69-0.98). Sex modified the effect of seasons on VPA: among boys, VPA occurred more frequently in the fall (Coef² = 1.72; 95%CI: 1.16-2.56) and winter (Coef² = 1.84; 95%CI: 1.26-2.69). Age modified the effect of the seasons on the SB: there were more SB in the 10-12 years age group, however, with a statistically significant difference only in the fall and early spring. LPA and SB increased during winter, but VPA decreased, especially among girls. Students aged 10-12 years had more SB in the fall and early spring
