The study

A total of 54 studies were included (almost all case-control studies); 22 studies had a low risk of bias, 19 had a moderate risk of bias, and 13 had a high risk of bias.

The outcomes assessed were esophageal adenocarcinoma and Barrett’s esophagus, a condition that can develop into esophageal cancer.

The following 5 factors were associated with Barrett’s esophagus:

  • Obesity (23% higher odds)
  • Male sex (36% higher odds)
  • Alcohol consumption (37% higher odds)
  • Tobacco smoking (42% higher odds)
  • Gastric reflux more than once a week (256% higher odds)

The only factor associated with esophageal adenocarcinoma was tobacco smoking (115% higher odds).
