Purpose: In this study, we evaluated the effectiveness of two years of an intervention with physically active lessons on indicators of sedentary behavior and physical activity measured objectively in elementary school children. Methods: A controlled clinical trial with cluster sampling was carried out in 2018 and 2019, with four classes of children...

The study was evaluated the effect of physically active lessons (PAL) on cognitive performance (ED) during two years of follow-up in children. Four classes were divided into two intervention classes (IG: n = 34) and two control classes (CG: n = 27). Five evaluations were performed; before the intervention (M1), after three (M2) and nine (M3) months...
Article
Background: To evaluate the effects of the introduction of physically active lessons on movement behaviors, cognitive, and academic performance in schoolchildren. Methods: This was a cluster-controlled trial. A total of 61 students from the second year of elementary school in a public school in Brazil made up 2 intervention classes (n = 34) with...

We analyzed the associations of screen-based behaviors with obesity, hypertension, and diabetes, and the moderation of different physical activity (PA) domains in these associations. We used data from the 2019 Brazilian National Health Survey, including data from 80,940 adults (mean age of 32.6 years). TV viewing, other screens (PC, tablet, and cel...

Background To identify the prevalence and sociodemographic correlates of different domains of physical activity (PA) and higher sitting time among South American adolescents. Methods Data from national surveys of 11 South American countries were analyzed, and comprised information on 166,901 adolescents. PA (≥ 60 min/day of moderate-vigorous PA),...
Article
Background We aimed to investigate time trends and inequalities of different physical activity (PA) domains and sitting time (ST) in adults from South American countries. Methods We included cross-sectional data of nationally representative surveys on adults (n = 597 843) from nine South American countries (Argentina, Bolivia, Brazil, Chile, Colom...

Our aim was to analyze the joint association of parental characteristics and offspring obesity indicators with metabolic risk in adolescents. A cross-sectional study was carried out with 972 adolescents and their parents. We observed that overweight adolescents who have a normal weight mother show lower metabolic risk in comparison with their count...

Our aim was to characterize the Brazilian studies that evaluated sedentary behavior, describing the main characteristics of the studies and identifying the used instruments. Using the PRISMA methodology, the search occurred on 25 August 2019 and was updated on 17 October 2020 in the following databases: PUBMED, LILACS, and SCIELO. Studies in Englis...
Article
Introduction: The authors’ objective was to identify the minimum number of days required to measure sedentary behavior and physical activity in children during school hours. Methods: Fifty-three children from four classes of the second year of elementary school in a public school in Brazil were selected. Sedentary behavior and physical activity wer...

Abstract: The objective of this study was to describe the profile of bicycle users, their perceived difficulty to cycle, and the most frequent trip origins and destinations in Aracaju, Northeast Brazil. Our cross-sectional study sampled 1001 participants and we collected information through structured interviews. Aged ≥15 years, participants were r...

The present study aimed to verify the contribution of different physical activity domains to “total physical activity” in Brazilian adolescents. This is a cross-sectional study using secondary data from the third edition of the National School Health Survey - PeNSE, 2015. The sample consisted of 100,497 adolescents of both sexes enrolled in the 9th...

The South American Physical Activity and Sedentary Behavior Network (SAPASEN) was designed to provide transnational empirical evidence about physical activity and sedentary behavior in South America, which represents 12% of world's surface and 6% of the global population. This sub-continent presents singular culture and distribution of diseases as well as lifestyle behaviors, especially due to an accelerated urbanization process, recent aging of population and considerable levels of poverty. This initiative aims to form a representative body of researchers and policy makers from all South America countries to establish priorities, targets and actions in short, medium and long-term. Vision Health promotion, disease control and prevention through active lifestyles improving populations wellbeing ​ Mission To bring researchers and policymakers across the South American continent together to conduct, support and stimulate research and to implement and promote evidence based strategies on physical activity and sedentary behavior. ​ Goals Establish and strengthen collaborations between South American researchers and policy- makers on physical activity and sedentary behavior Support and facilitate research on physical activity and sedentary behavior within and between South American countries Establish and strengthen collaborations with other networks. Provide up to date evidence on physical activity and sedentary behavior for the South American continent and in general. Promote continuing education on research in physical activity and sedentary behavior.
