Prevalence and risk factors of gastroesophageal reflux disease symptoms in Mazandaran, North of Iran: A Tabari cohort study
Abstract
Background: Gastro-esophageal reflux disease (GERD) is a very common complaint. It is a major health concern and there is paucity of information about the epidemiology of the disease and its risk factors in Iran, especially Mazandaran province (North of Iran). This study aimed at investigating the prevalence of regurgitation and the factors associated with this condition in Tabari cohort study. Methods: This was a cross-sectional study that analyzed data from Tabari cohort study. Information including the presence and frequency of heartburn and regurgitation, demographic characteristics, socioeconomic status, occupational history, history of chronic illnesses, history of alcohol and cigarette consumption were recorded. Results: The prevalence of GERD symptoms were 27.6% (20.4% in men, and 32.4% in women, p=0.0001). The frequency of typical symptoms was significantly higher in women than that in men. The risk of developing GERD symptoms were 1.7 times higher in women (p=0.0001). The highest prevalence of GERD symptoms was found in urban areas (41.8%, p=0.0001), in people with low educational levels (48%, p=0.0001), and in participants with history of depression symptoms (36.2%, p=0.0001). The prevalence of GERD symptoms was significantly high in individuals with higher BMI (29.5%, p=0.006), greater waist to hip ratio (29.1%, p=0.0001, p=0.0001), and high waist circumference (31.7%, p=0.0001). Conclusion: This study showed gender, region of residence, educational level, and…
