Association between 3-mile coverage of a good selection of fruits and vegetables and area deprivation or vehicle ownership, using multivariate linear regression model
| Model 1 | Access as number of shopping opportunities within 3 network 3 miles | |||
|---|---|---|---|---|
| Fresh fruits | Overall fruits | Fresh vegetables | Overall vegetables | |
| Deprivation | b (SE) | b (SE) | b (SE) | b (SE) |
| High | 0.98 (0.21)‡ | 1.58 (0.34)‡ | 0.75 (0.18)‡ | 1.21 (0.25)‡ |

NOTE: In models 1 and 2, the four equations were simultaneously estimated, controlling for population density. In model 1, deprivation entered as categorical variable; low deprivation is referent group. In model 2, vehicle ownership entered as categorical variable; high vehicle ownership is referent group. In both models, population density entered as continuous. Results are reported as multivariate-adjusted b (SE). Statistically significant variables are indicated as: *<0.05 †<0.01 ‡<0.001
