Abstract

CLARO, Rafael Moreira; LEVY, Renata Bertazzi  and  BANDONI, Daniel Henrique. Influence of income on food expenditures away from home among Brazilian families, 2002-2003. Cad. Saúde Pública [online]. 2009, vol.25, n.11, pp. 2489-2496. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X2009001100018.

This study describes and evaluates the influence of income on the percentage of food expenditures away from home for Brazilian families. Food acquisition data from the National Household Budget Survey conducted from 2002 to 2003 (POF 2002/2003) by the Brazilian Institute of Geography and Statistics (IBGE) or National Census Bureau was used in the analysis. Information on food-and-drink expenditures away from home was analyzed. The influence of income on the share of food purchased away from home in the household budget, adjusted for socio-demographic variables, was analyzed through elasticity coefficients estimated in multiple linear regression. Food purchased away from home accounted for 21% of total food expenditures by Brazilian households. A 10% increase in income increased the share of food purchased away from home by 3%. Income elasticity was high, especially for the lowest income families. The results demonstrate an important influence of income on food expenditures away from home, and higher income is associated with a greater share of food purchased away from home.
