NOTE: In both models, the four equations were simultaneously estimated, controlling for population density. In model 1 (fast-food opportunities within 1 network mile), deprivation entered as categorical variable; low deprivation is referent group. Model 2 estimates the relationships between deprivation and the number of fast-food opportunities within 3 network miles. In both models, population density entered as continuous variable. Results reported as multivariate-adjusted b (SE). Statistically significant variables are indicated as: *< 0.05 †< 0.01 ‡< 0.001 |
