Age-stratified prediction of obesity prevalence (BMI ≥ 30 kg/m2) for the Diogenes centers a.

aAge stratification was used alternatively for adjustment for baseline age in the prediction models (thus only follow-up time was taken as the independent variable).Age group of 40-49 year-old participants not present in the Danish centers. Age group of 60-65 y was not available in Amsterdam-Maastricht.bModel uses two points (baseline and follow-up).cDifference was calculated from subtracting the obesity prevalence for 2015 predicted by the leveling off model from the predicted value for 2015 of the linear model
