Study protocol and rationale of the “Cogni-action project” a cross-sectional and randomized controlled trial about physical activity, brain health, cognition, and educational achievement in schoolchildren

  • Published on July 26, 2019

Background Education and health are crucial topics for public policies as both largely determine the future wellbeing of the society. Currently, several studies recognize that physical activity (PA) benefits brain health in children. However, most of these studies have not been carried out in developing countries or lack the transference ...


Influence of air pollution exposure on adolescents’ objectively-measured physical activity and sedentary behavior

  • Published on July 22, 2019

Abstract Although regular physical activity is recommended for health, highly contaminated air exposure acts to the detriment of the benefits produced in individuals. The purpose of the present study was to compare the accelerometer-measured physical activity and sedentary behavior during the whole day, in-school time, out-of-school time, and school breaks ...



Community, household, and individual correlates of sleep behaviors in Guyanese female youth

  • Published on July 9, 2019

Objectives Chronic sleep loss among youth is a worldwide health problem. Since research on its predictors is often limited to high‐income countries, it is unclear if these findings are generalizable to all populations. To address this gap from an ecological perspective, we evaluated the associations between adolescents' sleep behaviors ...



Effects of the Girls on the Move randomized trial on adiposity and aerobic performance (secondary outcomes) in low‐income adolescent girls

  • Published on July 3, 2019

Background Limited, mixed evidence exists regarding the effectiveness of physical activity interventions on adiposity and aerobic performance in adolescent underrepresented populations. Objective To examine effects of Girls on the Move on body mass index z‐scores (BMI‐z), percent (%) body fat, and aerobic performance in fifth‐ to eighth‐grade underrepresented ...


Is sport enough? Contribution of sport to overall moderate- to vigorous-intensity physical activity among adolescents

  • Published on June 27, 2019

Objectives This study examined the contribution of sports participation to overall moderate-to-vigorous physical activity (MVPA) among adolescents, and explored potential moderators. Design Cross-sectional observational study using survey and accelerometry data drawn from the NEighbourhood Activity in Youth (NEArbY) study. Methods Adolescents (n = 358) were recruited from secondary schools in Melbourne, Australia. ...



Dietary saturated fat and low-grade inflammation modified by accelerometer-measured physical activity in adolescence: results from the GINIplus and LISA birth cohorts

  • Published on June 25, 2019

Background Saturated fatty acids (SFA) have been reported to promote inflammation. Nevertheless, evidence linking dietary SFA and low-grade inflammation in adolescents is scarce and inconsistent. The modulatory role of physical activity (PA) on fat metabolism and inflammation may provide a potential explanation. Thus, we assessed the association of dietary SFA ...


Associations between physical activity and sedentary time profiles transitions and changes in well-being in youth: The UP&DOWN longitudinal study

  • Published on June 25, 2019

Objectives The current study aimed at analyzing the associations between latent transitions based on sedentary time and physical activity levels and changes in Health-Related Quality of Life (HRQoL), positive affect, and negative affect over two years in children and adolescents. Design Longitudinal design. Methods Participants were 1099 children and adolescents (544 girls) ...
