title: Food groups and risk of prostate cancer: a case-control study in Uruguay.
abstract: OBJECTIVE
  The role of foods and beverages has been studied in detail in order to establish probable risk factors for prostate cancer.
  
  
  METHODS
  Data were derived from 326 cases with incident and microscopically confirmed adenocarcinomas of the prostate and 652 controls. Odds ratios and 95 % confidence intervals of prostate cancer were estimated by unconditional multiple logistic regression.
  
  
  RESULTS
  We identified the following food items as risk factors: lamb meat, salted meat, whole milk, total eggs, and maté consumption. The highest OR was associated with total eggs (OR, 2.43; 95 % CI, 1.70-3.48), followed by salted meat (OR, 2.65; 95 % CI, 1.36-3.76), maté consumption (OR, 1.96; 95 % CI, 1.17-3.31), and whole milk (OR, 2.01; 95 % CI, 1.26-2.51).
  
  
  CONCLUSIONS
  The final model, fitted by stepwise forward method, included total eggs, salted meat, whole milk, and maté consumption, whereas fruits were protective.
