Aims: To identify dietary patterns (DP) and to investigate their association with sociodemographic aspects.
Methodology: A cross-sectional data analysis of a sub-sample from Phase 4 of the Pró-Saúde Longitudinal Study (2012-2013), constituting a total of 520 participants. DP were obtained by principal component analysis from a food frequency questionnaire. Association between DP and sociodemographic aspects was analyzed by adjusted logistic regression.
Results: Four DP were identified: processed and ultraprocessed products; fresh food; meats and alcoholic beverages; and traditional Brazilian foods. There was a greater adherence chance to "processed and ultraprocessed products" pattern among adults ≥ 55 years and lower chance among men. The probability of adherence to "fresh food" pattern was directly associated to men, subjects with a high educational level and inversely associated to adults aged ≥ 60 years. There was a lower chance of "meats and alcoholic beverages" pattern among men and increased chance of adherence to "traditional Brazilian foods" pattern among whites, subjects with ≥ 60 years and low schooling.
Conclusion: Sociodemographic factors were important determinants of DP, especially gender, schooling and age. Presence of a DP composed of processed and ultraprocessed products indicates the need for awareness strategies and supply limitation in this population, since it affects their health.
