Association of mentally-passive and mentally-active sedentary behaviors with device-measured bouts and breaks of sedentary time in adolescents.

Our aim was to analyze the association of self-reported mentally-passive and mentally-active sedentary behaviors with different patterns (bouts and breaks) of device-measured sedentary time in adolescents. This was a cross-sectional study conducted among 375 adolescents (177 boys) aged 1015 years. Total time, bouts and breaks of sedentary time were measured through accelerometers.

Association(s) Between Objectively Measured Sedentary Behavior Patterns and Obesity Among Brazilian Adolescents.

Purpose: To investigate the association between patterns of sedentary behavior and obesity indicators among adolescents.

Methods: This was a cross-sectional study conducted among 389 adolescents (186 boys) aged 10-14 years. Body mass index, body fat (skinfolds), and waist circumference were adopted as outcomes.

Body adiposity from childhood to adolescence in boys: Interaction with somatic maturity.

Objectives: To investigate the longitudinal relationship between adiposity and maturity status throughout the transition between childhood and adolescence in boys, and the moderation effect of maturation on adiposity trajectories.

Methods: This was a longitudinal study conducted with 197 boys who were followed over 3 years (from childhood to adolescence). Body adiposity was estimated through the subcutaneous skinfold method, with measures of triceps and subscapular skinfolds.

Tracking of body adiposity indicators from childhood to adolescence: Mediation by BMI.

Our aim was to verify the tracking of body adiposity indicators from childhood to adolescence and analyze the mediation effects of BMI on the stability of body adiposity. Our sample was composed by 375 children (197 boys). The children were followed-up over 3 years.
