Active commuting to work, sex, age group, education and job characteristics were collected by telephone survey and transportation in the cities of Florianópolis, Curitiba and Porto Alegre, using absolute and relative frequencies with their respective 95% confidence intervals.

Clustering of Physical Activity, Diet and Sedentary Behavior among Youth from Low-, Middle-, and High-Income Countries: A Scoping Review.

Background: The interaction between physical activity (PA), diet, and sedentary behavior (SB) plays an important role on health-related outcomes. This scoping review (Prospero CRD42018094826) aims to identify and appraise clusters of PA, diet, and SB among youth (0-19 years) according to country income.

Methods: Five databases were searched.

Implementation of a school-based physical activity intervention for Brazilian adolescents: a mixed-methods evaluation.

The effectiveness of physical activity interventions can be improved through examining the aspects related to their implementation. However, little such evidence has been collected, particularly in low- and middle-income countries. This study aimed to evaluate the implementation of a school-based physical activity intervention with qualitative and quantitative data from different actors (students, teachers and parents) involved in developing the program.

Clustering of 24-h movement behaviors associated with cardiorespiratory fitness among adolescents: a latent class analysis.

This study aimed to examine the clustering of 24-h movement behaviors (moderate to vigorous physical activity, screen time, and sleep duration) and their association with cardiorespiratory fitness among adolescents. We evaluated 561 adolescents (52.1% girls; mean age, 13.

Clustering of screen time behaviours in adolescents and its association with waist circumference and cardiorespiratory fitness.

Objectives: To identify the association of clusters of screen time (ST) behaviours with waist circumference (WC) and cardiorespiratory fitness (CRF) among adolescents.

Design: Cross-sectional study of 574 adolescents (53% girls, 13 years), conducted in 2017.

Methods: Waist circumference was measured, a shuttle run was performed to assess CRF, and a questionnaire was applied.

Sociodemographic, biological, and psychosocial correlates of light- and moderate-to-vigorous-intensity physical activity during school time, recesses, and physical education classes.

Background: Identifying factors associated with physical activity (PA) is useful in planning interventions and policies. The aim of this study was to identify sociodemographic, biological, and psychosocial factors associated with PA performed in school settings.

Methods: Data collected for the present study included gender, age, socioeconomic status, body fat percentage, aerobic fitness, self-efficacy, attitudes, peer and parental support, and perception of school environment.

Effect of a Multicomponent Intervention on Lifestyle Factors among Brazilian Adolescents from Low Human Development Index Areas: A Cluster-Randomized Controlled Trial.

Promoting healthy lifestyle factors (e.g., physical activity, healthy eating, less screen time) among young people is a relevant and challenging step toward reducing non-communicable diseases.

School-Based Intervention on Cardiorespiratory Fitness in Brazilian Students: A Nonrandomized Controlled Trial.

Background: In response to the worldwide increasing prevalence of low cardiorespiratory fitness (CRF), several interventions have been developed. The aim of this study was to examine the effect of a school-based intervention on CRF in Brazilian students.

Methods: A nonrandomised controlled design tested 432 students (intervention group: = 247) from 6th to 9th grade recruited from two public secondary schools in Florianopolis, in 2015.

Are adolescents really being sedentary or inactive when at school? An analysis of sedentary behaviour and physical activity bouts.

This study analysed physical activity (PA) and sedentary behaviour (SB) performed in bouts during schooltime. Adolescents of two schools answered a questionnaire, had their height and weight measured and wore accelerometers during schooltime. Moderate-to-vigorous intensity PA was estimated in bouts of 2, 5 and 10 min, and SB in bouts of 5, 10, 30 and 60 min.

Dose-response between pedometer assessed physical activity, functional fitness, and fatness in healthy adults aged 50-80 years.

Objectives: This study examined dose-response relationships of walking with multiple aspects of physical function and measures of body fatness in apparently healthy, independent adults aged 50-80 years.

Methods: 201 adults (81 male, 120 female) aged 50-80 years underwent assessment of body mass index (BMI), body fatness, waist circumference (WC) and 6 measures of functional fitness. Sealed pedometery, worn over 7 days, was used to determine physical activity (PA).

Association between cardiorespiratory fitness and body fat in girls.

Objective: To estimate the prevalence of low cardiorespiratory fitness and its association with excess body fat, considering the sexual maturation and economic level in female adolescents.

Methods: Cross-sectional, epidemiological study of 1,223 adolescents (10-17 years) from the public school system of Cascavel, PR, Brazil, in 2006. We analyzed the self-assessed sexual maturation level (prepubertal, pubertal and post-pubertal), the Economic Level (EL) (high and low) through a questionnaire and body fat (normal and high) through triceps and subscapular skinfolds.

School-Based Interventions to Improve Cardiorespiratory Fitness in Adolescents: Systematic Review with Meta-analysis.

Background: School-based intervention can contribute to the promotion of cardiorespiratory fitness (CRF) in adolescents. However, it is neces sary to systematize how intervention strategies and the methodological characteristics of studies influence the effects of CRF interventions.

Objective: A meta-analysis review of school-based intervention studies aimed at increasing CRF in adolescents (10-19 years of age) was conducted.
