OBJECTIVES: Results from studies examining the association between alcohol consumption and the risk of Barrett%26apos;s esophagus have been inconsistent. We assessed the risk of Barrett%26apos;s esophagus associated with total and beverage-specific alcohol consumption by pooling individual participant data from five case-control studies participating in the international Barrett%26apos;s and Esophageal Adenocarcinoma Consortium. %26lt;br%26gt;METHODS: For analysis, there were 1,282 population-based controls, 1,418 controls with gastroesophageal reflux disease (GERD), and 1,169 patients with Barrett%26apos;s esophagus (cases). We estimated studyspecific odds ratios (ORs) and 95% confidence intervals (95% CI) using multivariable logistic regression models adjusted for age, sex, body mass index (BMI), education, smoking status, and GERD symptoms. Summary risk estimates were obtained by random-effects models. We also examined potential effect modification by sex, BMI, GERD symptoms, and cigarette smoking. %26lt;br%26gt;RESULTS: For comparisons with population-based controls, although there was a borderline statistically significant inverse association between any alcohol consumption and the risk of Barrett%26apos;s esophagus (any vs. none, summary OR = 0.77, 95% CI = 0.60-1.00), risk did not decrease in a dose-response manner (P-trend = 0.72). Among alcohol types, wine was associated with a moderately reduced risk of Barrett%26apos;s esophagus (any vs. none, OR = 0.71, 95% CI = 0.52-0.98); however, there was no consistent dose-response relationship (P-trend = 0.21). We found no association with alcohol consumption when cases were compared with GERD controls. Similar associations were observed across all strata of BMI, GERD symptoms, and cigarette smoking. %26lt;br%26gt;CONCLUSIONS: Consistent with findings for esophageal adenocarcinoma, we found no evidence that alcohol consumption increases the risk of Barrett%26apos;s esophagus.
