Purpose: To identify whether physical fitness (PF) components play a moderating role in the relationship between TV time and adiposity levels.

Design: Cross-sectional study.

Setting: Few studies have examined if different PF levels modify the association between TV time and adiposity in adolescents.

Background: Cardiorespiratory fitness (CRF) is considered a beneficial effect of physical activity (PA). PA and excessive screen time have implications for cardiometabolic risk.

Objective: To verify the association between screen time and CRF grouped by cardiometabolic risk factors.

Physical exercise reduces the biochemical markers of obesity, but the effects of multicomponent interventions on these markers should be explored. The present study aimed to elucidate how overweight/obese adolescents respond to a multicomponent program approach on body composition, physical fitness, and inflammatory markers, using a quasi-experimental study with 33 overweight/obesity adolescents (control group (CG) = 16; intervention group (IG) = 17). The intervention consisted of 24 weeks with physical exercises and nutritional and psychological guidance.

To verify the effect of a multicomponent intervention with overweight/obese adolescents on physical fitness, body composition, and insulin biomarkers. 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, = 17; Control-GC Group, = 20). The IGs were submitted to a multicomponent intervention for 6 months (three weekly sessions) consisting of physical exercises (sports, functional circuit, recreational, and water activities) and nutritional and psychological guidance.

Objective: The prevalence of overweight and obesity is gradually increasing in both developed and developing countries. Obesity, for instance, can present multifactorial causes that interact with each other. Among the important factors, parental obesity plays a prominent role in the onset of obesity during childhood and teenage years through genetics and ambient aspects.

Introduction And Objective: Pediatric hypertension has increased in the last decade, and it is thus crucial to identify the factors associated with the development of high blood pressure (BP) and other cardiovascular disorders. The aim of this study was to determine whether there is an association between high BP and sociodemographic and biochemical factors in schoolchildren.

Methods: This cross-sectional study included 1201 children and adolescents, between seven and 17 years old, of both sexes.

Background: The presence of dyslipidemia and behavioral aspects are determinants of cardiovascular risk, especially in childhood and adolescence.

Objective: To verify possible relationships between dyslipidemia, cultural factors, and cardiorespiratory fitness (CRF) in schoolchildren.

Methods: This cross-sectional study evaluated a sample of 1,254 children and adolescents between the ages of 7 and 17 from the South of Brazil, 686 of whom were female.
