  1. Abbreviations: CI, confidence interval; LSOA, lower super output area; ICC, intra-cluster correlation coefficient.
  2. a Possible range 1–5; higher score indicates more frequent consumption of unhealthy food items (chips, chocolate or sweets, and sugar sweetened beverages.
  3. b Range 1–5, 1 = very inactive, 5 = very active.
