Interventions on School Physical Activity Incorporating the Ecological Model in Latam
Meeting the recommendation of 60 minutes of daily physical activity for children and adolescents yields significant health benefits. In Latin-merican and the Caribbean, 39.1% of the population does not meet physical activity guidelines; specifically, 34.3% of males and 43.7% of females fall below the recommended levels. This study aims to identify school-based physical activity interventions aligned with the socioecological model that involve par…
Mental health and sleep quality across different physical activity intensities
BACKGROUND: Anxiety and depression symptoms are closely linked to sleep quality in a bidirectional manner. While physical activity (PA) is known to improve both mental health and sleep outcomes, it remains unclear whether the intensity of PA influences the relationship between sleep quality and symptoms of anxiety and depression. OBJECTIVES: This study aimed to assess the relationship between anxiety/depression symptoms and sleep quality across P…

Alarming low adherence to the 24-Hour Movement Behavior in adolescents — the Cogni-Action Project
Background: Unhealthy movement behaviors are a critical concern, particularly in developing countries and regions like Latin America. Evaluating adherence to the 24-Hour Movement Behavior (24-HMB) through a combination of objective and self-reported measures of moderate-to-vigorous physical activity (MVPA), adequate sleep duration (SD), and limited sedentary time (ST) is essential for understanding the interplay among these behaviors during adole…

Performance of international growth references to assess nutritional status in a sample of adolescents from Northeastern Brazil
This study aimed to assess the obesity diagnostic accuracy based on body fat mass (FM) in a sample of adolescents from northeastern Brazil, and to compare their nutritional status classified by the height and body mass index (BMI) references from the World Health Organization (WHO/2007), Centers for Disease Control And Prevention (CDC/2000), International Obesity Task Force (IOTF/2012), Brazil (2006) and MULT (2023). We selected 256 adolescents (…
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 …

METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…
Study protocol and rationale of “the UP project”
Background: Excessive sedentary time has been negatively associated with several health outcomes, and physical activity alone does not seem to fully counteract these consequences. This panorama emphasizes the essential of sedentary time interruption programs. "The Up Project" seeks to assess the effectiveness of two interventions, one incorporating active breaks led by a professional and the other utilizing a computer application (self-led), of b…
Association of meeting 24-hour movement guidelines with anxiety and depressive symptoms in adults
There is growing evidence on the association between meeting the recommendations of isolated movement behaviors (physical activity, sedentary time, and sleep) with anxiety and depressive symptoms. However, the joint association of meeting the 24 h movement guidelines with anxiety and depressive symptoms is still unknown. The aim of this study was to analyze the association of meeting 24-hour movement guidelines with symptoms of anxiety and of dep…
A comparative study between traditional and sports school uniforms on cardiorespiratory and muscular fitness and waist-height-to-ratio in adolescents

The aim of the present study was to primarily validate the submandibular skinfold as an anthropometric measurement of cardiometabolic risk in children, adolescents, and adults with intellectual disabilities, using a cross-s…
Comparison of Quality of Life in Breast Cancer Survivors with and without Persistent Depressive Symptoms
Although breast cancer treatments reduce mortality, their adverse effects can increase depression which impacts one's quality of life (QoL). Physical activity (PA) seems to improve the QoL of breast cancer survivors (BCS). However, an unanswered question is the influence of PA on the QoL in BCS with depressive symptoms. Thus, we analyzed the influence of PA on the QoL in BCS with persistent depressive symptoms during 12 months of follow-up. The s…

Translation and Validation of the Basic Psychological Need Satisfaction in Active Commuting to and from School (BPNS-ACS) Scale in Young Portuguese Students
Active commuting to and from school (ACS) is a strategy to enhance physical activity levels in youths. To promote ACS, it is important to understand the factors that lead to this behaviour. With this in mind, an adaptation of the Basic Psychological Needs in Exercise Scale for ACS was developed, named the Basic Psychological Need Satisfaction in Active Commuting to and from School (BPNS-ACS) scale. This study aimed to translate and evaluate the p…
