In all models, the dependent variable was SSB consumption (g/d), and the independent variable was sodium intake (390 mg/d). Model 2a was unadjusted. Model 2b was adjusted for age, sex, race-ethnic group, socioeconomic status, and energy derived from sources other than SSBs (kcal/d). Age and sex were not adjusted for in the stratified models. For R2 values, the second value in each cell represents the F test of the overall signficance of the regression model. SSB, sugar-sweetened beverage.
