Prevalence of Gastroesophageal Reflux Disease, Its Association With Eating Behavior and Psychological Disturbance, and Its Impact On Quality Of Life, Among Medical Students In The MENA Region, A Multinational Cross-Sectional Study
Gastroesophageal reflux disease (GERD) is a common gastrointestinal disease. It is a chronic condition that is characterized by the regurgitation of stomach contents into the esophagus and is associated with heartburn. The occurrence of these symptoms for at least two weeks increases the likelihood of having GERD. Other GERD symptoms include chest pain, nausea, dysphagia, burping, water brash, and vomiting. All these symptoms negatively affect the patients' quality of life. The pathophysiology of GERD is multifactorial. Several factors have been suggested to cause GERD, including a hypotensive lower esophageal sphincter (LOS) and a defect in the gastric sling/clasp muscle fiber component.
The global prevalence of GERD is about 13.98% with variation among different countries and ethnic groups. In East Asia, it ranges from 2.5% to 7.5%, 8.5 to 25.9% in Europe, 18.1% to 27.8% in South and North America, and about 11.6% in Australia. In the Middle East, it ranges from 8.7% to 33.1%.
Several risk factors have been identified that increase the likelihood of having GERD. Obesity was found to be one of the risk factors that increases GERD. Also, dietary habits such as spicy food, coffee drinks, or administering NSAIDs increase the prevalence of having GERD.
On the other hand, psychological factors also play an important role in GERD severity. Both stress and anxiety are linked to an increase in GERD. A previous study showed that stress can increase heartburn symptoms in patients with heartburn and also increase in anxiety level was associated with an increase in esophageal reflux. Finally, depression was found to be associated with GERD, which can be explained by a change in the eating behavior in depressed patients.
Rationale Medical students suffer from a study burden, which increases their level of anxiety and stress. They also have a higher likelihood of having trouble with eating behavior or having a lot of coffee daily. This increases their likelihood of having GERD. In the Middle East, fewer studies have assessed the effect of GERD. A recent cross-sectional study assessed the prevalence of GERD among medical students in Egypt. They found a prevalence of 17.1%. They found an association between increasing stress levels and increasing GERD severity. Also, smoking was a significant risk factor for GERD symptoms. Another cross-sectional study among medical students in 21 universities in Egypt. They reported a prevalence of 28.4%. Again, they found that an increasing level of stress and anxiety was associated with increasing GERD severity. Finally, Two cross-sectional studies were conducted in Saudi Arabia. They reported a prevalence of 23.8% and 23.1% respectively. To our knowledge, no study has assessed the GERD and its related quality of life among medical students in Middle East and linked their findings with eating behaviour
