Background/aims: We aimed to establish the prevalence and demographic determinants of gastroesophageal reflux disease in the Turkish general population using the Turkish version of the gastroesophageal reflux disease questionnaire. Material and Methods: A total of 8143 volunteers (mean age: 38.5 (13.3) years; 52.3% males) were included in this cross-sectional questionnaire study conducted via face-to-face administration of the questionnaire forms including items on sociodemographic features, past history of gastric disorders, gastroesophageal reflux disease, the influence of reflux symptoms on patients' lives, physician visits, diagnostic tests, and reflux medications. Results: A past history of gastric symptoms was reported in half of the population. More female participants (p<0.001) had a past history of gastric symptoms that yielded a previous diagnosis of gastroesophageal reflux disease in 19.1% of the population. The likelihood of gastroesophageal reflux disease was low in the majority (75.3%) of the subjects evaluated. Gastroesophageal reflux disease with an inconveniencing or disrupting impact on the patient's life was present in 17.9% and 6.8% of the population. Total gastroesophageal reflux disease-questionnaire scores and reflux prevalence were higher in older age groups (p<0.001). Females were more likely to have gastroesophageal reflux disease prevalence based on reflux symptoms. The impact of gastroesophageal reflux disease on sleep and psychological I emotional well-being was more pronounced in older and female patients, whereas the impact on eating/drinking behaviors and physical-social activities was more marked among females independent of their age (p<0.001). Reflux prevalence was higher in subjects from East Anatolia, Central Anatolia, Mediterranean, and Black Sea regions of Turkey (p<0.001 for each). Conclusions: Prevalence and demographic determinants of gastroesophageal reflux disease are compatible with the profile of the disease in the other Western populations, with a predilection for females and older individuals.
