    Although the effect of diet on health status is widely recognized, few studies have evaluated the profile of fat consumption by the Brazilian population. The imbalance in the consumption of omega-6:omega-3 (n6:n3) fatty acids is related to inflammatory processes that increase the risk of developing non-communicable chronic diseases. The aim of this study was to analyze the associations between the ratio of n6: n3 fatty acids and sociodemographic, food and health variables. This is a research carried out with secondary data from the ISA-Camp, a population-based cross-sectional study with a sample stratified by clusters and in two stages, conducted between 2008-09, in the city of Campinas, SP, Brazil. Fat intake was estimated using the 24-Hour Recall, and data were entered into the Nutrition Data System for Research software. In the analysis of the data, the means of the n6:n3 ratio were calculated according to the independent variables, using simple and multiple linear regression, with significance level of 5%. The food records of 3,303 individuals, aged 10 years or more, were considered. Lower values of the n6:n3 ratio were observed in the strata of adults and elderly (p <0.001), in those who ate fruits, vegetables and milk daily (p <0.01), and in those who were physically active in leisure time (p < 0.009). These findings show the association between eating habits, sociodemographic indicators and the n6:n3 ratio, and may contribute to the elaboration of strategies aimed at the adoption of changes in lifestyle.
