Epidemiological and laboratory research has shown that dietary components are associated with the risk of developing urinary tract tumors (UTT). Objective: The purpose of this case-control study, conducted between 2004 and 2008 in Cordoba, a Mediterranean city in Argentina, was to describe the role of dietary patterns and to investigate any association with the risk of developing UTT. Methods: 168 patients with histologically confirmed transitional UTT, and 334 controls with acute, non-neoplastic, and non-urinary tract diseases from the same hospitals were studied. All subjects were interviewed about their food habits and their exposure to a number of known or suspected risk factors for UTT. Multiple correspondence analysis was used to explore dietary patterns and data analysis was performed by calculating Odds Ratios and their 95% confidence intervals by using Multiple Logistic Regression. Results: Two main dietary patterns were identified: a “prudent” pattern was linked to controls whereas a “western” pattern was associated with cases. A very frequent intake of vegetable oils, lean meats, grains and fruit, the moderate use of alcohol (mainly red wine) together with potato and sweet consumption, and the habit of taking at least four meals per day, were associated with a reduced risk for UTT. On the other hand, a very frequent consumption of infusions (mainly maté), potatoes, alcohol, sweets and processed meat resulted in a high risk for UTT. Conclusions: The dietary patterns of our population have a role in the development of UTT, thus implying that appropriate nutritional education may decrease this risk.
