Age Differences in the Relationship Between Outdoor Physical Activity and School Emotional Well-Being in Pre-Adolescents
Outdoor PA modestly associates with lower stress in older pre-adolescents but may be associated with elevated peer conflicts. This dual effect adds nuance to interventions, highlighting supervision needs. Age-tailored, supervised school interventions could optimize emotional benefits during late pre-adolescence
Prediction of Children’s Subjective Well-Being from Physical Activity and Sports Participation Using Machine Learning Techniques
Background/Objectives : Traditional models like ordinary least squares (OLS) struggle to capture non-linear relationships in children's subjective well-being (SWB), which is associated with physical activity. This study evaluated machine learning (ML) for predicting SWB, focusing on sports participation, and explored theoretical prediction limits using a global dataset. It addresses a gap in understanding complex patterns across diverse cultural …
Gender Differences in School Stress and Academic Satisfaction in Pre-Adolescents
Physical activity modestly protects against school-related boredom and stress in pre-adolescents, with modest gender moderation. Findings support universal school programs promoting daily exercise, with gender-sensitive adaptations, to enhance emotional well-being and academic satisfaction
Association between trust in the incumbent president and Covid-19 preventive behaviors during the pandemic in four Latin American countries
The COVID-19 pandemic revealed disparities in policy responses in Latin America. We examined the association between trust in the president and COVID-19 preventive behaviors in Brazil, Chile, Colombia, and Mexico. We used data from the Collaborative COVID-19 Response Survey by the McDonnell Academy at Washington University in St. Louis (United States), from September 2020 to March 2021. Nonprobabilistic sampling included adult citizens from the f…
Self-perception of mental health, Covid-19 and associated sociodemographic-contextual factors in Latin America
This study aimed to estimate the prevalence of alterations in self-perceived mental health during the COVID-19 pandemic and their associated factors in four Latin American countries. This is a cross-sectional study based on data collected from adults in 2021 through the Collaborative Response COVID-19 Survey by the MacDonnell Academy at Washington University in St. Louis (United States). The sample was composed of 8,125 individuals from Brazil, C…
Consumo de álcool e drogas ilícitas e envolvimento de adolescentes em violência física em Pernambuco, Brasil
O objetivo foi estimar a prevalência e analisar a associação do consumo de álcool e drogas ilícitas com indicadores de violência física em adolescentes. Estudo transversal repetido com estudantes do Ensino Médio em escolas da rede pública em Pernambuco, Brasil (2006, n = 4.207; 2011, n = 6.264). Os dados foram obtidos por questionário. Os indicadores de violência física foram: vitimização por violência física; envolvimento em brigas. As variáveis…
