  1. For girls: Trajectory 2 = Late Onset Overweight, Trajectory 3 = Early Onset Obese to Overweight, Trajectory 4 = Early Onset Obese to Morbidity Obese
  2. Summary statistics presented as mean (±standard deviation) otherwise stated
  3. *P < 0.05; **P < 0.01; ***P < 0.001
  4. ANOVA and chi square test were conducted to describe the study characteristics differences in BMI trajectories
  5. Percentages may not add up to 100 % due to rounding
