Abstract

BACKGROUND
The reports that obesity could be associated with upper gastrointestinal disorders such as gastritis, gastric ulcer, duodenal ulcer, reflux esophagitis have not been consistent. Therefore, we studied the association between esophagogastroduodenoscopic (EGD) findings and the related risk factors of obesity.
METHODS
The study subjects include 2,210 adults who visited the Health Promotion Center of one university hospital from January 2006 to December 2006. All subjects had standard physical measurements as well as resting blood pressure, fasting blood glucose, HbA1c, serum lipids, and gastroendoscopic examination. BMI was classified into two groups (BMI > or = 23 kg/m2, normal; BMI < 23 kg/m2, overweight or obese). The study subjects were classified into four groups according to the EGD findings; normal, gastritis, gastric or duodenal ulcer, reflux esophagitis.
RESULTS
Mean BMI of gastritis, gastric or duodenal ulcer, and reflux esophagitis groups were higher than normal group after adjusting age, sex, alcohol and smoking (P < 0.001). Gastritis risk (OR, 2.098; 95% CI, 1.195 to 3.682; P = 0.01), gastric or duodenal ulcer risk (OR, 2.562; 95% CI, 1.282 to 5.117; P = 0.008), and reflux esophagitis risk (OR, 2.856; 95% CI, 1.522 to 5.360; P = 0.001) were significantly higher in overweight and obesity group compare with normal weight group after adjusting age, sex, alcohol and smoking.
CONCLUSION
We suggest that overweight or obesity is the risk factor of gastritis, gastric or duodenal ulcer, and reflux esophagitis.
