- *Significantly different from the reference (p < 0.05)
- aChange in outcome in categories of activity status relative to quitting activity as reference. Model 1 adjusted for baseline measurement of outcome. Model 2 adjusted for baseline measurement of outcome, screen time on weekdays, regularity of eating breakfast, age in half years at baseline and days between measurements
- bBoys quitting activity had a mean increase of 1.5 BMI units, 4.1 cm waist circumference, 1.0 FMI units and 0.3 LMI units
- cGirls quitting activity had a mean increase of 1.0 BMI units, 1.4 cm waist circumference, 0.9 FMI units and − 0.1 LMI units
