The Global Matrix of Physical Activity in Children and Adolescents in Latin America
Objective. To synthesize the grades of physical activity (PA) indicators for children and adolescents (5–17 years) in Latin American countries; explore the social determinants of health (SDoH) for PA indicators; and identify strengths, weaknesses, opportunities, and threats to improve PA levels. Method. Participating Latin American countries graded a set of common PA indicators following the harmonized methodology established by the Global Matrix…
Goldilocks day
These findings concur with current guidelines that more MVPA and less SB are better, but the optimal time youth should spend in each behaviour depends on the health outcome of interest. This indicates that one size does not fit all when making recommendations for multiple cardiometabolic health outcomes
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…

Global Matrix 4.0 Physical Activity Report Card Grades for Children and Adolescents
Background : The Global Matrix 4.0 on physical activity (PA) for children and adolescents was developed to achieve a comprehensive understanding of the global variation in children’s and adolescents’ (5–17 y) PA, related measures, and key sources of influence. The objectives of this article were (1) to summarize the findings from the Global Matrix 4.0 Report Cards, (2) to compare indicators across countries, and (3) to explore trends related to t…
Physical activity-related indicators in children and adolescents in Uruguay
Background: The first Uruguay's Report Card in 2018 based on the Global Matrix initiative showed the lack of information on physical activity in children and adolescents. This study mapped and examined the available evidence on physical activity-related indicators based on Uruguay's 2022 Report Card. Methods: The scoping review was reported using the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews extension for Sc…
Relationship between rs9939609 FTO polymorphism with waist circumference and body fat is moderated by ponderal index at birth in youth
Time trends and inequalities of physical activity domains and sitting time in South America
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, Colombia, Ecuador, Peru, Uruguay, and Venezuela), with data collection time frames ranging from 2005 to …
Association of Cardiovascular Risk Factors between Adolescents and Their Parents Is Mitigated by Parental Physical Activity—A Cross-Sectional Study
The parental physical activity level seems to mitigate the association of CVRF between adolescents and their parents. The promotion of an active lifestyle at the family level can contribute to reduce CVRF among adolescents
Measurement of resting muscle oxygenation and the relationship with countermovement jumps and body composition in soccer players (Medición de la oxigenación muscular en reposo y la relación con los sa…
The measurement of resting muscle oxygenation capacity is under investigation in team sports. The aim of the current study was to observe the changes after a preseason, in muscle oxygen saturation (SmO2) at rest and the relationship with body composition and jump power in soccer players. 17 soccer players (age 21.8 ± 2.2 years) were enrolled. Body composition, somatotype, countermovement jump (CMJ) and single-leg countermovement jump (SLCMJ) were…
Changes in Healthy Behaviors and Meeting 24-h Movement Guidelines in Spanish and Brazilian Preschoolers, Children and Adolescents during the Covid-19 Lockdown
The prevalence of preschoolers, children and adolescents in both the Spain and Brazil samples meeting the 24-h movement guidelines during COVID-19 restrictions was as low as previous studies in other countries. Efforts to protect and support healthy behaviors of young people during a period of pandemic restrictions need to be a priority
Cardiorespiratory Fitness as Mediator of the Relationship of Recreational Screen Time on Mediterranean Diet Score in Schoolchildren
This research supports that cardiorespiratory fitness may reduce the negative association between screen time and Mediterranean dietary patterns
A Multicomponent Intervention Program With Overweight and Obese Adolescents Improves Body Composition and Cardiorespiratory Fitness, but Not Insulin Biomarkers
Objective: To verify the effect of a multicomponent intervention with overweight/obese adolescents on physical fitness, body composition, and insulin biomarkers. Methods: A quasi-experimental study with 37 adolescents, aged 10 to 17 years, of both sexes, overweight and obese, allocated in two groups (Intervention—IG Group, n = 17; Control—GC Group, n = 20). The IGs were submitted to a multicomponent intervention for 6 months (three weekly session…
Meeting the Physical Activity Recommendations and Its Relationship with Obesity-Related Parameters, Physical Fitness, Screen Time, and Mediterranean Diet in Schoolchildren
The up-to-date scientific evidence suggests that adequate levels of physical activity provide essential health benefits for children and adolescents and help to maintain a healthy body weight. In this sense, children and adolescents should at least accumulate 60 min of moderate-to-vigorous physical activity in a daily basis to achieve these benefits and be considered active. Likewise, some lifestyle-related elements may interact with each other i…
Weight Status Is Related to Health-Related Physical Fitness and Physical Activity but Not to Sedentary Behaviour in Children
Purpose: The aim of this research was to describe, examine, and compare the level of physical fitness, physical activity, and sedentary behaviour in pupils aged 6-13 in the Region of Murcia, Spain, in accordance with weight status. Methods: A total of 370 children (166 girls and 204 boys) aged 6-13 (M = 8.7; DT = 1.8) from the Region of Murcia participated in this descriptive and cross-sectional study. Some anthropometric parameters such as body …
Health-Related Factors in Rural and Urban Mexican Adolescents from the State of Jalisco
Mexico shows a high prevalence of obesity in children and adolescents. Geographical location and cultural environment could play a role in the promotion of healthy lifestyles in terms of physical activity (PA), sedentary behavior (SB) and nutrition. The purpose of this study was to assess rural and urban differences in body composition (BC), physical fitness (PF), PA and nutritional status of adolescents from the state of Jalisco (Mexico). The st…

Methods : Work group…
Descriptive Epidemiology of Uruguayan Adults’ Leisure Time Physical Activity
Policymakers rely on information for describing and monitoring levels of physical activity among the population. However, in Uruguay there is no research presenting physical activity practices nationwide. The present study aims to describe the leisure time physical activity levels and their unequal distribution among Uruguayan adults. Data from the 2014 Uruguayan National Health Survey ( n = 3543 adults aged > 15 years) were analysed. Physical ac…
