Data are β coefficients (95% CI). n = 1,254. Model 1: adjusted for sex, age-group, country, maturity, and SES. Model 2: adjusted for sex, age-group, country, maturity, SES, monitor worn time, and MVPA (minutes per day). Model 3: adjusted for sex, age-group, country, maturity, SES, monitor worn time, and average physical activity (counts per minute). Model 4: adjusted for sex, age-group, country, maturity, SES, monitor worn time, total physical activity (counts per minute), and aerobic fitness (watts per kilogram FFM).

*Additionally adjusted for adolescent height.
