  1. SSB sugar sweetened beverages
  2. Each model is adjusted for all model-specific variables displayed in the Table plus age and gender
  3. Categorization for SSB consumption in 2002: never SSB; low SSB consumption (less than 200 ml/d); moderate SSB consumption (between 200 and less than 700 ml/d); high SSB consumption (700 ml/d and more)
  4. aPhysical activity level was estimated using the Flemish Physical Activity Questionnaire [9]
