摘要：Background: Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal problems in the west while different reports indicate an increase in the prevalence in Iran. The aim of this study was to estimate the prevalence and clinical spectrum of GERD in staff of a referral hospital and evaluate the risk factors.Methods: This cross-sectional study using a modified Mayo clinic questionnaire was performed on staff of Imam Hospital, Tabriz, Iran on a pilot of 50 subjects, and a randomly selected group consisted of 522 subjects in the year 2005. GERD symptoms were defined as at least weekly heartburn and/or acid regurgitation during the past year.Results: Response rate was 95%. Mean age of responders was 40.02±10.72 yr. The prevalence of recurrent heartburn and/or acid regurgitation experienced at least weekly and monthly was 26.8% and 34.1%, respectively. They were not related to age and gender. The severity of symptoms was mainly reported of a mild to moderate degree. 45% of the cases reported at least one of the atypical symptoms. There was no relation between marriage status and prevalence of GERD. On the other hand, GERD was less common among cases with no family history of upper gastrointestinal disease. The prevalence of frequent GERD was more common among medical staff. Increased BMI (but no recent weight gain or lose) was associated with higher prevalence of GERD symptoms only in women. Interestingly 33% of our population had a history of using antacid or PPIs which was more among cases with frequent GERD symptoms.Conclusion: This study revealed a high prevalence of frequent GERD symptoms in a selected population of Tabriz. Atypical symptoms should be considered in this area.
