Psychological factors, lifestyle habits, and their association with gastroesophageal reflux disease among Egyptian university students: A cross-sectional study.

Gastroesophageal reflux disease (GERD) is a common condition among university students that is associated with various lifestyle and psychological factors. The study aims to evaluate the association of psychological factors, physical activity, and dietary habits with the prevalence of GERD among university students in Egypt. An analytical cross-sectional study was conducted from March 2024 to May 2024, selecting students from different universities in Egypt. A self-administered questionnaire covered sociodemographic characteristics, and GERD assessment using the Gerd Q questionnaire. Generalized Anxiety Disorder-2, Perceived Stress Scale 4, Nordic Physical Activity Questionnaire, and short dietary habits questions were used to assess anxiety, perceived stress, physical activity, and dietary habits, respectively. Statistical analysis included descriptive statistics, correlation analysis, and hierarchical logistic regression, which were employed to identify significant predictors of GERD. Among the 2241 university students, 22.6% had GERD (GerdQ score > 8), 86.3% had high perceived stress, and 62.2% had high anxiety levels. Hierarchical logistic regression analysis identified old age, high weight, short height, frequent consumption of fried/fast food, and high anxiety levels as significant predictors of GERD. The study underscores the importance of considering psychological factors and dietary habits alongside traditional risk factors in understanding and addressing GERD among university students in Egypt. Public health interventions targeting psychological well-being and healthier dietary habits will play a pivotal role in reducing this population's GERD burden.
