The risk factors found were: age (OR:2.57; IC95%, 1.41-4.69, p0.00), antecedent of esophagitis (OR: 14.61; IC95%, 3.96-55.41, p0.00) spend pork meat cooked fried (OR: 8.67, IC95%, 2.28-32.99; p0.00). Female was a protect factor (OR: 0.23;IC95%; 0.05-1.05; p0.06) considered at 10%. CONCLUSIONS.-This study found prevalence 0.30% of BE prevalence and the risk factors were: males up 60 years old, antecedent of esophagitis of gastro esophageal reflux, spend pork meat, preference to cook fried food.
