TABLE 4—

Adjusted Income and Price Elasticity Coefficients for the Household Consumption of SSBs: Household Budget Survey–Brazilian Institute of Geography and Statistics, Brazil, 2002–2003

	Household Strata
Variables	All Income Quartiles	First Income Quartile	Second, Third, and Fourth Income Quartiles
Monthly per capita income, R$	0.41	0.43	0.22
Price of SSBs, R$/1000 cal	−0.85	−1.03	−0.63
R2	0.76	0.58	0.59

Note. SSB = sugar-sweetened beverage. All regression coefficients are statistically significant (P < .05). We adjusted coefficients for geographic region and urban or rural status of the household stratum, proportion of members aged ≥ 65 years, and mean price of the set of foods and beverages complementary to SSBs. We obtained price elasticity coefficients in 3 separate log–log linear regression models.
