Gastroesophageal reflux disease symptoms in the Greek general population: prevalence and risk factors

BACKGROUND AND AIMS Population-based data regarding the prevalence of gastroesophageal reflux disease (GERD) in Greece are very poor. This study estimated the prevalence of GERD symptoms and their risk factors in the Greek adult population. METHODS A self-administered questionnaire was answered by a randomly selected population of 340 subjects. The question regarding "heartburn, chest pain, indigestion, or stomach acid coming up" as included in the Reflux Symptom Index was used for prevalence assessment. RESULTS The monthly prevalence of GERD symptoms was found to be 52.0% in the Greek general population, with no statistically significant difference between the two sexes (P>0.05). The age group of 65-79 years showed a higher prevalence rate of GERD. Symptom severity was found to be mild (59.3%) or moderate (27.1%). The number of cigarettes smoked daily (but not smoking duration) as well as the number of alcoholic drinks consumed daily (but not the duration of alcohol drinking) were found to be related to GERD symptoms. No reported concomitant disease or medication was found to be related with GERD symptoms. CONCLUSION The prevalence of GERD symptoms in the Greek general population was found to be 52.0%. Tobacco smoking and alcohol drinking but not concomitant disease or medications were found to be related with GERD symptoms.
