To investigate the correlation between certain unhealthy lifestyles and the incidence of gastroesophageal reflux disease (GERD), thus to provide the lifestyle guidelines for GERD patients. Methods: Retrospective study were conducted for 402 GERD and 276 non-GERD out-patients in Department of Gastroenterology, Third Xiangya Hospital, Central South University from August, 2014 to August, 2015 based on questionnaire survey, then the correlation of unhealthy lifestyles with GERD were analyzed. Results: The top 10 common symptoms for GERD were as follows: reflux, acid regurgitation, postprandial fullness, heartburn, swallow obstruction or pain, epigastric burning sensation, paraesthesia pharynges, poststernal pain, chronic laryngopharyngitis, and chronic cough. The top 8 unhealthy habits closely related to GERD were as follows: fast-eating, over-eating, spicy preferred diet, sweets preferred diet, anxious, soup preferred diet, high-fat diet, and hot eating. Single-factor analysis showed that GERD was markedly correlated to gender (male), age (≥60 years), BMI, smoking, alcohol, fast-eating, over-eating, hot-eating, spicy preferred diet, high-fat diet, acid preferred diet, sweets preferred diet, hard food preference, strong tea preference, coffee preference, immediately on bed after meal, difficult defecation, dyscoimesis, anxious, and too tight belt, respectively (P<0.05). Logistic multiple regression analysis indicated that the largest risk factor for GERD was the fast-eating (OR=3.214, 95% CI 2.171 to 4.759, P<0.001) followed by the over-eating (OR=2.936, 95% CI 1.981 to 4.350, P<0.001), elderly population (OR=2.047, 95% CI 1.291 to 3.244, P=0.002), too tight belt (OR=2.003, 95% CI 1.013 to 3.961, P=0.046), and hot-eating (OR=1.570, 95% CI 1.044 to 2.362, P=0.030). Conclusion: The elderly people are at high risk for GERD, and unhealthy habits like fast-eating, over-eating, too tight belt, and hot-eating is closely related to GERD. The lifestyles such as chewing food thoroughly, splitting the meals up, warm and cool diet, keeping patients out of the too tight belt are necessary for GERD patients.
