Methods We utilized baseline data from 7,552 subjects who underwent upper endoscopy for health screening in a prospective, multicenter cohort study. The subjects were asked to complete a questionnaire detailing their upper abdominal symptoms and lifestyle. Based on the heartburn and/or acid regurgitation frequency, the EE subjects were stratified into the following three groups: (1) at least one day a week (symptomatic EE [sEE]), (2) less than one day a week (mild symptomatic EE [msEE]), and (3) never (asymptomatic EE [aEE]). Postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS) were defined according to the Rome III criteria. Results Of the 1,262 (16.7%) subjects (male 83.8%, mean age 52.6 years) with EE, the proportions of sEE, msEE and aEE were 15.0%, 37.2% and 47.9%, respectively. The sEE group showed significant associations with overlapping EPS (OR: 58.4, 95% CI: 25.2–160.0), overlapping PDS (OR: 9.96, 95% CI: 3.91–26.8), severe hiatal hernia (OR: 2.43, 95% CI: 1.43–4.05), experiencing high levels of stress (OR: 2.20, 95% CI: 1.43–3.40), atrophic gastritis (OR: 1.57, 95% CI: 1.03–2.36) and Los Angeles (LA) grade B or worse (OR: 1.72, 95% CI: 1.12–2.60) in the multivariate analysis. Conclusions Approximately one-sixth of EE subjects were symptomatic. A multifactorial etiology, including factors unrelated to gastric acid secretion, was associated with the symptom presentation of EE subjects.
