Abstract
Epidemiologic data regarding coffee and tea consumption and risk of esophageal inflammation, Barrett's esophagus (BE), and adenocarcinoma are sparse and inconclusive. This study examined the association between consumption of tea or coffee with risk of BE. We conducted a cross-sectional study among US veterans, comparing 310 patients with histologically confirmed BE with 1728 individuals with no endoscopic or histopathologic features of BE (controls). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression models. In univariate models, we found a statistically significant association between risk of BE and consumption of coffee (OR, 1.41; 95% CI, 1.06-1.87) or tea (OR, 1.34; 95% CI, 1.05-1.71). However, in multivariate analysis, in which models were adjusted for confounders including sex and race, we found no association between risk of BE and consumption of coffee (adjusted OR, 1.04; 95% CI, 0.76-1.42) or tea (adjusted OR, 1.11; 95% CI, 0.85-1.44). These data do not support an association between consumption of coffee or tea and the risk of BE. It is unlikely that avoidance of coffee or tea will protect against BE.
