1 Covariates labeled with an * indicate that the variable was significantly associated with unadjusted SSB consumption p<0.20 according to an f-test of independence

2 Values represent the average number of 12 oz. servings ± the standard deviation

3 Wald tests on linear regression coefficients were implemented to determine if the observed value was significantly different than the reference value; the first row below each covariate name represents the reference value

4 Measured as a percent of the Federal Poverty Level

a Significantly different than the reference value at p<0.05

b Significantly different than the reference value at p<0.01

c Significantly different than the reference value at p<0.001
