Introduction: Increasing evidence suggests that the dietary intake of children can be influenced by family income and this condition may be associated with development of obesity. This study aims to evaluate the association between food intake, family income and childhood obesity in children in the municipalities of Oeiras, Seixal and Viana do Castelo. Methodology: Data from MUN-SI project (2010/2011) was analysed regarding food consumption, family income and children´s nutritional status. 1585 children aged 9-11 years old were evaluated. CDC criteria was used to classify nutritional status. Descriptive analysis consisted on obtaining frequencies of the explanatory variables. The binomial logistic regression model was used in order to calculate odds ratio for confidence intervals at 95%. Results: 31,1% of children were overweight and 14.4% were obese. Children whose family income was 501-850€/month had a significantly increased risk of developing obesity (OR = 2.919; 95% CI: 1,428-5,966). Children whose family income was 0-500€/month and 501-850€/month, consumed fast food (9,2%; 4,8%), salty snacks (11,5%; 5,6%), candy (10,9%; 10,6%) and ice cream (9,5%; 8%) more than 3 times per week (p<0,05), and fruit (47,7%; 37,5%) and vegetable soup (34.3%; 27.8%) less than one time per day (p<0,05). Conclusion: Families with low income may represent a risk for developing childhood obesity. This reinforces the need for public health advocates and the continuity of community and family based projects interventions at local level.
