Adjusted prevalence of non-cavitated caries (white spots) and cavitated caries (dmf-s index) according to the interaction between child age (≤2 and >2 to 3 years) and daily ultra-processed food consumption (up to three times and four times or more) in children aged 0–3 years old (n 309) (Pelotas/RS, Brazil, 2015). *Adjusted for caregiver educational attainment and duration of breast-feeding; P
interaction effect = 0·012. **Adjusted for caregiver age, duration of breast-feeding and dental service utilisation. P
interaction effect = 0·381. , children aged >2 to 3 years with daily consumption of ultra-processed food four times or more (n 123); , children aged ≤2 years with daily consumption of ultra-processed food four times or more (n 27); , children aged >2 to 3 years with daily consumption of ultra-processed-foods up to three times (n 86); , children aged ≤2 years with daily consumption of ultra-processed-foods up to three times (n 73)
