RESUMO

Objective. Analyze the influence of income and food prices on fruits and vegetables share of household food consumption in São Paulo city. Methods. The data obtained through Family Budget Survey (POF) from Fundacao Instituto de Pesquisas Economicas (FIPE), concerning the population of the city of Sao Paulo during the period of 1998 and 1999, was the base in this study. The household nutritional patterns were described by means of the relative participation of 18 food groups in total calories monthly acquired for home consumption. Income and food prices? influence on fruits and vegetables share was assessed through the use of multiple regression analysis techniques (Log-Log model) in order to estimate income elasticity and price elasticity coefficients. Results. Statistically significant effects of income (positive effect), fruits and vegetables prices (negative effect) and other foods prices (positive effect) were identified. Magnitude comparison among the effects observed, through comparison of elasticity coefficients, indicates a major effect from fruits and vegetables price (1% increase in prices results in a 0.2% reduction in the share of fruits and vegetables), an intermediate effect from other foods prices (1% increase in prices results in a 0.07% increase in the share of fruits and vegetables) and a smaller effect from income (1% raise in household income would achieve a 0.04% increase in the share of fruits and vegetables). The effect of household income and F&V price was similar in different income classes, while the effect of other food prices declined in higher income classes Conclusion. Public policies for reducing fruit and vegetables? prices should be the most recommended line of action in order to obtain an increase in fruit and vegetables? consumption in Sao Paulo city or any other similar urban centers.
