Mosli YR 2023 UL http://smj.org.sa/content/44/5/509.abstract AB Objectives: To determine the prevalence of hiatal hernia (HH) and its association with age, gender, and body mass index (BMI).Methods: We retrospectively included patients who underwent esophagogastroduodenoscopy (EGD) at an academic tertiary care hospital. Data were collected on the presence of HH as well as patient demographics including age, gender, and BMI. Univariate and multivariate analysis were done to determine risk factors for HH.Results: A total of 2805 patients were included in this study. The mean age was 48.6 (±18.6) years and males constituted 28.8% of the study population. The mean BMI was 29.7 (±8.6) kg/m². The prevalence of HH was 29.8% among all patients and 48.6% among those who underwent EGD for gastroesophageal reflux disease–related indications. There was no significant association between HH and female gender (OR 1.04, 95%CI: 0.88 -1.26, p=0.53), older age (OR 0.77, 95%CI: 0.72 - 1.06, p=0.19) or BMI (OR 1.07, 95%CI: 0.9 – 1.2, p=0.39).Conclusion: The prevalence of HH was 28.9% based on this large endoscopy-based population. We found no association between HH and gender, age, or BMI.
