Abstract:
BACKGROUND: The prevalence of obesity is increasing year after year in Korean; and gastroesophageal reflux disease(GERD) is increasing in this population as well. The aim of this study is to assess the association between age, body mass index(BMI) and GERD in healthy Korean adults. METHODS: Analysis was done on 1,016 subjects who had not had malignancy, uncontrolled metabolic disease, enteric surgery and organic esophageal disease. They completed a questionnaire that included past history and reflux symptoms. Endoscopy was performed by two gastroenterologists who were not given any patient information. Existence of GERD was determined by the esophageal syndrome criteria of the Montreal guidelines. Subjects were categorized by BMI, initially as: underweight, normal(18.5< or =BMI<25), overweight(25< or =BMI<30) and obese by the WHO criteria, and then as: underweight, normal(18.5< or =BMI<23), overweight(23< or =BMI<25) and obese by the Asian-Pacific criteria. RESULTS: The overall[is this correct] prevalence of GERD in our subjects was 15.5%. Age and sex were not correlated factors for GERD. By the WHO and the Asian-Pacific criteria, GERD was present in underweight(10.0%, 12.1%), normal(13.9%, 14.4%), overweight(18.6%, 13.0%) and obese groups(21.0%, 18.8%). No meaningful association was seen between BMI and GERD in either of the classified groups. Erosive GERD was seen in 83 subjects (8.2%) on endoscopy. The obese(BMI> or =25) group(12.1%) showed a meaningful increment in the prevalence of erosive GERD compared to the non-obese(BMI<25) group(6.2%)(p value 0.002). CONCLUSION: The prevalence of GERD in healthy Korean adult subjects was not closely associated with obesity and age[according to BMI]; however, erosive GERD was found to have a strong association with obesity.
