Acc – Physical activity evaluated by raw data accelerometer; MVPA – Moderate-to-Vigorous Physical Activity; BMI – Body Mass Index; WC – waist circumference; SBP – Systolic Blood Pressure; DBP – Diastolic Blood Pressure.
Variables included in the analysis as base confounders: sex, skin color, family income at birth, National Economic Indicator score and smoking.
Variables included in the analysis as post confounder: daily energy intake.
