| dc.description.abstract | Background. Gastroesophageal Reflux Disease (GERD) is an event where the Lower Esophageal Sphincter (LES) weakens, resulting in reflux of stomach acid fluid into the esophagus which can cause serious interference with the quality of life and daily activities. Factors that increase the risk of gastroesophageal reflux are gender, race, pregnancy, diabetes, history of pregnancy, smoking and body mass index. The higher the body mass index, the higher the risk of GERD. Many studies have proven that there is an increase in GERD symptoms in individuals who have a high body mass index compared to individuals who have a normal body mass index. Body mass index is classified into 5 categories, underweight (<18.5), normal (18.5 – 22.9), overweight (23 - 24.9), type 1 obesity (25 - 29.9), type 2 obesity (≥30). Subject and Method. This study used a case control design and used scales, stature meters, and data collection tools in the form of a questionnaire containing questions about risk factors for GERD, namely age, ethnicity, blood type, physical activity, smoking history, BMI, and GERD-Q. The research sample consisted of medical students from the University of North Sumatra, selected through consecutive sampling, and the research was carried out within the Faculty of Medicine, University of North Sumatra. The data analysis method used is the Chi-square correlation test. Results. With 226 respondents, the results of this study showed that there was a significant correlation between body mass index and the incidence of GERD (P = 0.001). Conclusion. It can be concluded that there is a significant relationship between body mass index and the incidence of GERD. | en_US |
