BACKGROUND: Professions distinguished by repeated vocal stress carry a high risk of developing gastroesophageal reflux symptoms (GERS) which may affect vocal performance. AIMS: To investigate the prevalence of self-reported GERS in professional opera soloists. METHODS: A validated questionnaire regarding self-reported GERS (heartburn, regurgitation, chest pain, dysphagia, hoarseness, and cough) and lifestyle habits was administered to 116 professional opera soloists (mean age 34.1 ± 7.3 years, F:M ratio 1:1.1). Age and sex-matched opera choristers and control subjects were used as control. Prevalence rate ratios (PRRs) adjusted for confounding factors were evaluated. RESULTS: Among GERS, belching (33.6%), heartburn (19.8%), and dysphagia (15.5%) were the most commonly reported by soloists. In particular, a higher risk of heartburn (PRR 2.61, 95% CI 1.45-4.69) and dysphagia (PRR 2.58, 95% CI 1.31-5.10) was reported in soloists as compared to choristers. The prevalence of obesity and late dinner was higher in both choristers and soloists in comparison to the population sample (p
