Sedentary time has a stronger impact on metabolic health than moderate to vigorous physical activity in adolescents with obesity: a cross‐sectional analysis of the Beta‐JUDO study

Summary Background Relationships between movement‐related behaviours and metabolic health remain underexplored in adolescents with obesity. Objectives To compare profiles of sedentary time (more sedentary, SED+ vs. less sedentary, SED−), moderate to vigorous physical activity (MVPA) time (more active, MVPA+ vs. less active, MVPA−) and combinations of behaviours (SED−/MVPA+, SED−/MVPA−, SED+/MVPA+, SED+/MVPA−) in regard to metabolic health. Methods One hundred and thirty‐four subjects (mean age 13.4 ± 2.2 yrs, mean body mass index [BMI] 98.9 ± 0.7 percentile, 48.5% females) underwent 24 h/7 day accelerometry, anthropometric, body composition, blood pressure (BP), lipid profile and insulin resistance (IR) assessments. Results Metabolic health was better in SED− [lower fat mass (FM) percentage (p
