Energy-Adjusted Dietary Costs Associated With Likelihood of Having a DASH-Accordant Diet (n=9,724)

Exposure measure	Model 1	Model 2	Model 3	Model 4
Dietary costs
T1	0.34 (0.30, 0.40)	0.40 (0.35, 0.46)	0.40 (0.35, 0.46)	0.40 (0.35, 0.46)
T2	0.65 (0.58, 0.73)	0.70 (0.62, 0.79)	0.71 (0.63, 0.80)	0.71 (0.63, 0.81)
T3	1	1	1	1

Note: Values are OR (95% CI). Achieving a DASH-accordant diet was defined as a DASH score >28. Coefficients were derived from logistic regression analyses. Boldface indicates statistical significance (p<0.05). T1 is the tertile with lowest dietary costs, while T3 is the tertile with highest dietary costs (reference group). Model 1 is an unadjusted model. In Model 2 associations are adjusted for individual-level covariates (age, sex, educational level, and energy intake). In Model 3, associations are additionally adjusted for income. In Model 4, associations are additionally adjusted for distance to the nearest supermarket.
