Background: Strategic health interventions must be guided by effective surveillance systems that monitor population trends and patterns, therefore we aimed to provide youth's (6-14 years) national prevalence estimates of physical activity (PA), active outdoor play (AOP), sedentary behaviur (SB), and structured PA (SPA).
Methods: Measures of moderate-to-vigorous PA, SB, AOP, and SPA, were obtained for 719 participants in 2 groups (6-9 and 10-14 years) using diaries and questionnaires. National estimates were calculated, by sex, region, and parental education.
Aim: The aim of our study was to analyze physical activity levels, sitting time, physical fitness, and their relationship with depressive symptoms after home confinement in previously active older adults.
Methods: This cross-sectional study sample comprised 68 older adults (74.24 ± 5.
The objective of this study was to observe the home-confinement effects on physical fitness, physical activity (PA), and body composition in active older adults, and to compare physical fitness and PA according to quality of life (QoL) during confinement. A total of 72 physically active older adults (61.1% females; 74.

METHODS Cross-sectional study with a random sample of 1,130 high school students (47.3% girls; aged 14 to 20 years old) from Porto Alegre, Brazil.

Design: School-based cross-sectional study. The DII was calculated based on dietary information obtained from a single 24h dietary recall.
Article Synopsis
- The study examines how children (specifically boys and girls) allocate their active time across four domains: transport, school, leisure, and home.
- It found that transport was the leading domain for moderate-to-vigorous physical activity (MVPA), particularly for girls, while boys had higher MVPA levels in school and leisure activities.
- The results suggest that interventions to boost children's physical activity should focus on enhancing transport behavior and creating supportive school environments, taking gender differences into account.
Objective: The aim of this study was to investigate the association between self-efficacy, enjoyment, and volitional control with active commuting, as well as to analyze the impact of social support from parents, friends, and teachers with active commuting to school.
Methods: Participants in this cross-sectional study were 625 students (male: 46.3%) aged 10 to 15years from Porto, Portugal (2010/2011).
Background: Parents are likely to be a basic influence on their children's behavior. There is an absence of information about the associations between parents' physical activity and perception of neighborhood environment with children's independent mobility.The purpose of this study is to examine the contribution of parental physical activity and perception of neighborhood safety to children's independent mobility.

Methods: Data were collected from 9 middle-schools in Porto (Portugal) area. A total of 636 children in the 6th grade (340 girls and 296 boys) with a mean age of 11.
Is walking to school associated with improved metabolic health?
Int J Behav Nutr Phys Act
January 2013
Background: Active commuting to/from school is an important source of physical activity that has been declining over the past years. Although it is an affordable and simple way of increasing physical activity levels it is still unclear whether it has enough potential to improve health. Therefore, the aim of this cross sectional study was to examine the relationship between active commuting to/from school and metabolic risk factors in 10 to 12 year old children.
