Objectives: Few studies have investigated the influence of polyunsaturated fatty acid consumption on excessive weight gain during pregnancy. Thus, we analyzed the association between the intake of polyunsaturated fatty acids (ω‐6 and ω‐3) and weight gain in women during pregnancy. Methods: This is a cohort study of 250 pregnant women enrolled in municipal pre‐natal services. Weight, height, and dietary intake of polyunsaturated fatty acids were evaluated at the baseline. The semi‐quantitative food frequency questionnaire was employed to assess the main exposure. Gestational weight was measured in the first, second, and third trimesters. A dietary pattern involving the consumption of fatty acids was identified through factor analysis. A generalized estimating equation was used for the data analysis. Results: The prevalence of excessive weight gain at the end of pregnancy was 35.2%. Consumption patterns 1 (salted meats, offal, vegetable oil, snacks, legumes, and oleaginous foods) and 2 (red meat, sausages, butter, margarine, mayonnaise, acarajé, caruru, vatapá, and refined cereals) revealed a risk for the accumulation of excess weight during pregnancy. Women who adhered to consumption patterns 1 (RR: 2.39; 95% CI: 1.44–3.94) and 2 (RR: 2.39; 95% CI: 1.44–3.94) were more susceptible to excess weight gain during pregnancy. Conclusions: Women who adhered to dietary patterns involving foods that are sources of ω‐6 fatty acids and saturated fatty acids were more susceptible to gaining weight during pregnancy compared to those who adhered less to these patterns.
