Background The presence of multimorbidity increases the risk of mortality, and identifying correlates of multimorbidity can direct interventions by targeting specific modifiable correlates. Here we aimed to investigate the association between two types of screen-based behaviors and multimorbidity. Methods We used data from 87,678 Brazilian adults...

Abstract Aims: This study aimed to compare the sedentary time measured using the ActiGraph GT3X accelerometer with the measurement of sitting and standing time obtained by ActivPAL inclinometers. Methods: This was a cross-sectional study conducted with a sample of 60 schoolchildren (34 males) of one elementary public school in Brazil. The students...

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
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...
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...
Article

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...

Aims: (i) to compare the running performance of non-professional female runners from different Brazilian states; (ii) to estimate the relationship between environmental state-related variables and running performance; and (iii) to analyze the mediation role of training commitment in the relationship between the environment and running performance....

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...

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
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...
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...
Article
Full-text available
Background Our aim was to analyze the association of the presence of public physical activity (PA) facilities and participation in public PA programs with leisure-time PA, with an emphasis on the moderating role of educational level and income. Methods We used data of 88,531 adults (46,869 women), with a mean age of 47.2 ± 17.1y, from the 2019 Bra...
Article
Background : We tested whether stressful workplace characteristics confound or moderate the association between occupational physical activity and depressive symptoms. Method : We used data of 36,442 employed adults (16,992 women), with a mean age of 39.3±12.6y, from the 2013 Brazilian National Health Survey. Depressive symptoms were assessed thro...

Objectives To characterize how physical activity and sedentary behavior have been measured in national health surveys in South American countries. Methods An extensive search was made for national health surveys from all 12 South American countries through health websites, national statistical offices, and contact with researchers and policy-maker...
Article
Full-text available
We aimed to investigate correlates of TV viewing and other types of screen-based behaviors in a nationally representative sample of Brazilian adults. In the 2019 Brazilian National Health Survey (including 88,509 adults), TV viewing time and other types of screen behaviors (computer, tablet, and cellphone use) were self-reported and different geogr...
Article
Background: The authors analyzed time trends and sociodemographic inequalities in different physical activity and sedentary behavior domains between 2003 and 2019. Methods: A secondary analysis of data from 5 cross-sectional Brazilian epidemiological surveys (World Health Survey-2003, National Household Sample Survey-2008/2015, and Brazilian Hea...

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.
