  1. Abbreviations: EDF Energy dense foods, F&V Fruit and vegetables, PA physical activity
  2. aFour studies [73, 74, 78, 82] are omitted from this table as it was not possible to summarise the findings of studies that created composite scores across two or three domains of the HE. Details of these studies can be found in Table 1
  3. bOne study [59] examining caregiver modelling of PA reported different findings by the type of activity modelled: Modelling of commuting to school/work by bike or walking was associated with lower BMI Z-score (r = − 0.062) but modelling of vigorous PA was not associated with BMI z-score or waist circumference
