a Model 0 = uncontrolled. 2118 postcode districts included. Model 1 = controlled for postcode district rural urban classification, population density, and the number of food outlets within their boundary. 2088 postcode districts included.
b Incidence Rate Ratios (IRR) represent expected difference of outcome at each level of deprivation, compared to the reference group.
