Background: The aim of this study was to identify the changes in the structure of weekly physical activity (PA) and well-being among adolescent boys and girls between habitual education (HE) and distance education (DE) during the pandemic in secondary schools. Methods: The research was carried out in 12 Czech and 18 Polish schools during 2019 to…

Background: Since children are generally not achieving desirable levels of physical activity (PA), schools can provide an opportunity to increase their active time. This study aimed to describe individual- and social-level variables associated with PA at school recess in a culturally diverse primary school. Methods: This observational…

Background: The aim of the study is to analyze the associations between depressive symptoms (DS), well-being and different types of physical activity (PA) in adolescents. Methods: Overall, 368 girls and 228 boys aged 15-19 years were involved in the research. To explore the composition of weekly PA, we used the IPAQ-Long questionnaire, and a…

Background: In this study, we examined moderate-to-vigorous physical activity (MVPA) of children in a school district serving children from low-income and minority households. Methods: This observational study was conducted in 8 rural elementary schools in South Carolina. Children (N = 719, age = 7.7 years, 48.0% girls, 88.0% African American)…

BACKGROUND: The 2020 World Health Organization Guidelines on Physical Activity and Sedentary Behavior are the first to provide evidence-based recommendations for reducing both dimensions of languorous behavior. The relationship between sitting time and exercise remains understudied among diverse adolescent populations worldwide. METHODS: The 2017…

Background: This study aims to quantify associations between one's weight management goal and eating behaviors and physical activity among teenagers. Methods: Weighted logistic regressions were performed predicting healthy behaviors from weight goal separately for boys and girls while controlling for age, body mass index, socioeconomic indicators,…

Background: The purpose of this study was to characterize the temporal, social, and physical contexts for physical activities commonly reported in a diverse cohort of 753 boys and girls from fifth to seventh grade. Methods: Data were obtained from a multilevel longitudinal study, the Transitions and Activity Changes in Kids. The Physical Activity…

Background: Adolescent girls are likely to be less active than adolescent boys. A range of factors including multiple psychosocial aspects are thought to influence their engagement in physical activity (PA). This study aimed to explore adolescent girls' perceptions and experiences of school-based PA to inform a subsequent intervention, the Girls…

Background: Some Canadian schools have modified their daily schedules from the traditional school day (TSD) schedule (two 15-minute breaks and one 60-minute break) to a balanced school day (BSD) schedule (two 40-minute breaks). While this change increases daily planning and instructional time, it also changes the amount of time available for…

Background: The aims were to: (1) examine the levels of physical activity (PA) during different time periods (ie, daily PA, school hour PA, recess PA, physical education classes [PEC] PA) in children and adolescents; and (2) identify the rate of compliance with the specific PA recommendations for these time periods. Methods: The participants were…

Background: School initiatives aimed at increasing physical activity (PA) may improve the health of children in low-income communities. Methods: Assessors completed 5909 observations of students' PA during leisure periods using a validated instrument in 19 schools in low-income Latino communities. We examined relationships between school…

Background: Among adolescents, physical inactivity and unhealthy dietary habits are associated with being obese. We know little about how those are associated with trying to lose weight. Methods: We analyzed the 2013 Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Surveillance data (N = 13,583) to examine how obesity and…

Background: School-based programs, such as Playworks, that guide students in organized activities during recess and make improvements to the recess play yard may lead to significant increases in physical activity--especially for girls. This study builds on past research by investigating the impact of Playworks separately for girls and boys.…

Background: Research suggests that perceived weight poses separate risks from objective weight on adolescents' risks of being bullied. We examined if the prevalence of bullying victimization differed by perceived and objective weight status, and how these associations varied by sex. Methods: Data were analyzed for 6716 8th and 11th graders from…
