All the models (sitting time as predictor variable) were adjusted for age, sex, BMIz, season and accounted for clustering by school. Model A: Minimally adjusted model; Model B: adjusted for LIPA; Model C: adjusted for Low-LIPA; Model D: adjusted for High-LIPA and Model E: adjusted for MVPA. Values in the table are displayed in bold when the association p-value is < 0.005
Abbreviations BMIz = body mass index z-score; WCz = waist circumference z-score; SBP = Systolic Blood Pressure; DBP = Diastolic Blood Pressure; HDL = High-Density Lipoprotein; LDL = Low-Density Lipoprotein; FPG = fasting plasma glucose; Vitamin D = 25hydroxyvitaminD; LIPA = Light Intensity Physical Activity (Total); low-LIPA = Low Light-Intensity Physical Activity (101 − 3.99 METS); low-LIPA = Low Light-Intensity Physical Activity (101–799 counts per minute); high-LIPA = High Light-Intensity Physical Activity (800 counts per minute– 3.99 METS); MVPA = Moderate- to- Vigorous-intensity Physical Activity (≥ 4 METS)
