ASSOCIATION BETWEEN GASTROESOPHAGEAL REFLUX SYMPTOMS AND PHYSICAL ACTIVITY IN ADOLESCENTS

Abstract

Background: We reported a prevalence of 38% of esophageal GER (E-GER) symptoms at least once per month in adolescents. We are now analyzing the association between E-GER symptoms and various levels of physical activity (PA). Methods: A cross sectional, 2 part survey was given to 14-19 year old students. Part I determined the frequency (none to daily) and severity (slight discomfort to heavy interference with daily activities and inability to sleep) of E-GER symptoms (heartburn, regurgitation, and dysphagia) over the past year. Part II, the Fels PA Questionnaire, determined the level of PA for the last year (summing the unique intensity and frequency of each sport played). The sports scores were divided into 3 groups: LOW 1-2.33, MED 2.34-3.67, and HIGH 3.68-5. Data was analyzed by chi-square. Results: 1478 (89%) surveys analyzed. Mean age 16.3 years (±1.2), 53% female. Predominant ethnicity: Caucasian (43%), Asian (32%) and Hispanic (13%). E-GER symptoms were present at least monthly in 544 (37%). Average activity score was 3.00 (±0.86). Daily prevalence of regurgitation and dysphagia were found to be similar (5.9%) across all three activity levels (P =.78). Conclusions: There is a non-linear relationship between monthly heartburn and physical activity, and a linear relationship between daily heartburn and physical activity. There is a non-linear relationship between the severity of esophageal GER symptoms and physical activity. No relationship exists between the frequency of dysphagia or regurgitation and physical activityTable: Distribution of the frequency of heartburn amongst physical activity levels
