RESUMO
Introduction: Breast cancer is one of the main types ofcancer in women. Previous studies assessed the relationshipbetween diet and breast cancer risk, however, studies thatevaluate the relationship between diet and mammographicfindings are scarce. Aim: To evaluate the association between dietary patternsand mammographic findings of women monitored by a mas-tology service of the Brazilian Unified Health System. Materials and Methods: Cross-sectional study that eval-uated data from 504 women. Two 24-hour dietary recallswere applied and dietary patterns were identified by principalcomponent factor analysis. The mammography reports wereclassified into normal and altered mammographic findings. Logistic regression models were applied to evaluate the asso-ciation between dietary patterns and mammographic findings.The analyses were performed in the software Stata and R andconsidered significant values of p <0.05. Results: Three dietary patterns was identified: traditionalBrazilian (rice, beans, red meat, breads, oils and fats andcoffees and teas), Western (sugar sweetened beverages, eggs, cakes, pies and cookies, fast-food snacks and, sweetsand desserts) and prudent (whole grains, fruits, vegetables,tubers and their products, dairy and chicken). Women withless adherence (OR 0.54 CI 95% 0.30:0.95) to the traditionalBrazilian dietary pattern had 46% lower odds for having al-tered mammographic findings. No associations were foundbetween Western and prudent dietary patterns with mam-mographic findings.(AU)
