^*Intercepts not reported ^#Interaction effects between BMI SDS at the end and at the start of the periods were not included in models B, because they were all non-significant,

^**F-test for comparing the multiple regression model with the simple regression model is significant (P<0.001),

^&values of β, β₁ and β₂ are adjusted for gender and the age at the measurement of BMI SDS at young adulthood, – Not applicable, Adj R² adjusted variance.
