Linear relation between BMI SDS at young adulthood and BMI SDS at earlier age: Model A includes one <i>status score</i> as independent variable (a), model B is model A extended with the preceding BMI SDS^# (b) as independent variable.

*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.
