The eating habits of children are severely constrained to the purchasing power of parents, which depend on availability, quality and quantity of food consumed, directly influencing the daily consumption of vitamins with antioxidant properties, important for the prevention of chronic diseases and specific nutritional deficiencies. This study aimed to examine the relationship between family income and daily consumption of &#946;-carotene, vitamin C and vitamin E among children in the city of João Pessoa/PB, Brazil. This is a population-based cross-sectional study conducted in the municipality of João Pessoa/PB, involving the five Health Districts defined by the City Hall Health Department. One hundred and eighty-three children aged 2 to <10 years were evaluated, in a sample stratified by income level representative of the population of Joao Pessoa. The research instrument consisted of questionnaires addressing socio-economic, demographic, epidemiological, anthropometric and food consumption variables. The results were analyzed with the R software, using descriptive (mean, median, standard-deviation, simple and relative frequency and percentage) and inferential statistics (correlation and regression). Participants were predominantly male (55.29%) from income classes E (up to U.S. $ 428.64) and C (> U.S. $ 622.31 - U.S. $ 2,682.93) and mothers who have studied nine years or more. As for the intake of vitamins, there was low inadequacy of vitamin C (7.65%) and high inadequacy of vitamin E (59.41%), the latter being more frequent in the age group of 4-8 years (32.94% of children). There was an inverse correlation between income and energy intake (r = -0.1525, p <0.05) and between income and consumption of vitamin E (r = -0.3, p <0.05). The relationship between income and maternal education (p <0.05), between income and consumption of &#946;-Carotene and between income and consumption of vitamin C was significantly positive (r = 0.33 and r = 0.28, respectively, p < 0.05). It was concluded that the consumption of vitamins with antioxidant properties is positively related to family income in relation to vitamin C and &#946;- carotene, and negatively with respect to vitamin E and calories.
